These tools are not meant to be installed. Often one needs to edit the source code a little to make the programs do the wanted things. If you don't know how these programs could help you, it is likely that they really are useless to you. These aren't intended to be used as example programs. They take some shortcuts here and there, which correct programs should not do. Many possible errors (especially I/O errors) are ignored. Don't report bugs or send patches to fix this kind of bugs. xz-5.1.3alpha/debug/Makefile.am0000644000000000000000000000074012232714400013174 00000000000000## ## Author: Lasse Collin ## ## This file has been put into the public domain. ## You can do whatever you want with this file. ## EXTRA_DIST = \ translation.bash noinst_PROGRAMS = \ repeat \ sync_flush \ full_flush \ memusage \ crc32 \ known_sizes \ hex2bin AM_CPPFLAGS = \ -I$(top_srcdir)/src/common \ -I$(top_srcdir)/src/liblzma/api LDADD = $(top_builddir)/src/liblzma/liblzma.la if COND_GNULIB LDADD += $(top_builddir)/lib/libgnu.a endif LDADD += $(LTLIBINTL) xz-5.1.3alpha/debug/Makefile.in0000644000000000000000000005272312232714504013222 00000000000000# Makefile.in generated by automake 1.14 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2013 Free Software Foundation, Inc. # This Makefile.in is free software;

Introduction This directory contains bunch of files to test handling of .xz files in .xz decoder implementations. Many of the files have been created by hand with a hex editor, thus there is no better "source code" than the files themselves. All the test files (*.xz) and this README have been put into the public domain. 1. File Types Good files (good-*.xz) must decode successfully without requiring a lot of CPU time or RAM. Unsupported files (unsupported-*.xz) are good files, but headers indicate features not supported by the current file format specification. Bad files (bad-*.xz) must cause the decoder to give an error. Like with the good files, these files must not require a lot of CPU time or RAM before they get detected to be broken. 2. Descriptions of Individual Files 2.1. Good Files good-0-empty.xz has one Stream with no Blocks. good-0pad-empty.xz has one Stream with no Blocks followed by four-byte Stream Padding. good-0cat-empty.xz has two zero-Block Streams concatenated without Stream Padding. good-0catpad-empty.xz has two zero-Block Streams concatenated with four-byte Stream Padding between the Streams. good-1-check-none.xz has one Stream with one Block with two uncompressed LZMA2 chunks and no integrity check. good-1-check-crc32.xz has one Stream with one Block with two uncompressed LZMA2 chunks and CRC32 check. good-1-check-crc64.xz is like good-1-check-crc32.xz but with CRC64. good-1-check-sha256.xz is like good-1-check-crc32.xz but with SHA256. good-2-lzma2.xz has one Stream with two Blocks with one uncompressed LZMA2 chunk in each Block. good-1-block_header-1.xz has both Compressed Size and Uncompressed Size in the Block Header. This has also four extra bytes of Header Padding. good-1-block_header-2.xz has known Compressed Size. good-1-block_header-3.xz has known Uncompressed Size. good-1-delta-lzma2.tiff.xz is an image file that compresses better with Delta+LZMA2 than with plain LZMA2. good-1-x86-lzma2.xz uses the x86 filter (BCJ) and LZMA2. The uncompressed file is compress_prepared_bcj_x86 found from the tests directory. good-1-sparc-lzma2.xz uses the SPARC filter and LZMA. The uncompressed file is compress_prepared_bcj_sparc found from the tests directory. good-1-lzma2-1.xz has two LZMA2 chunks, of which the second sets new properties. good-1-lzma2-2.xz has two LZMA2 chunks, of which the second resets the state without specifying new properties. good-1-lzma2-3.xz has two LZMA2 chunks, of which the first is uncompressed and the second is LZMA. The first chunk resets dictionary and the second sets new properties. good-1-lzma2-4.xz has three LZMA2 chunks: First is LZMA, second is uncompressed with dictionary reset, and third is LZMA with new properties but without dictionary reset. good-1-lzma2-5.xz has an empty LZMA2 stream with only the end of payload marker. XZ Utils 5.0.1 and older incorrectly see this file as corrupt. good-1-3delta-lzma2.xz has three Delta filters and LZMA2. 2.2. Unsupported Files unsupported-check.xz uses Check ID 0x02 which isn't supported by the current version of the file format. It is implementation-defined how this file handled (it may reject it, or decode it possibly with a warning). unsupported-block_header.xz has a non-null byte in Header Padding, which may indicate presence of a new unsupported field. unsupported-filter_flags-1.xz has unsupported Filter ID 0x7F. unsupported-filter_flags-2.xz specifies only Delta filter in the List of Filter Flags, but Delta isn't allowed as the last filter in the chain. It could be a little more correct to detect this file as corrupt instead of unsupported, but saying it is unsupported is simpler in case of liblzma. unsupported-filter_flags-3.xz specifies two LZMA2 filters in the List of Filter Flags. LZMA2 is allowed only as the last filter in the chain. It could be a little more correct to detect this file as corrupt instead of unsupported, but saying it is unsupported is simpler in case of liblzma. 2.3. Bad Files bad-0pad-empty.xz has one Stream with no Blocks followed by five-byte Stream Padding. Stream Padding must be a multiple of four bytes, thus this file is corrupt. bad-0catpad-empty.xz has two zero-Block Streams concatenated with five-byte Stream Padding between the Streams. bad-0cat-alone.xz is good-0-empty.xz concatenated with an empty LZMA_Alone file. bad-0cat-header_magic.xz is good-0cat-empty.xz but with one byte wrong in the Header Magic Bytes field of the second Stream. liblzma gives LZMA_DATA_ERROR for this. (LZMA_FORMAT_ERROR is used only if the first Stream of a file has invalid Header Magic Bytes.) bad-0-header_magic.xz is good-0-empty.xz but with one byte wrong in the Header Magic Bytes field. liblzma gives LZMA_FORMAT_ERROR for this. bad-0-footer_magic.xz is good-0-empty.xz but with one byte wrong in the Footer Magic Bytes field. liblzma gives LZMA_DATA_ERROR for this. bad-0-empty-truncated.xz is good-0-empty.xz without the last byte of the file. bad-0-nonempty_index.xz has no Blocks but Index claims that there is one Block. bad-0-backward_size.xz has wrong Backward Size in Stream Footer. bad-1-stream_flags-1.xz has different Stream Flags in Stream Header and Stream Footer. bad-1-stream_flags-2.xz has wrong CRC32 in Stream Header. bad-1-stream_flags-3.xz has wrong CRC32 in Stream Footer. bad-1-vli-1.xz has two-byte variable-length integer in the Uncompressed Size field in Block Header while one-byte would be enough for that value. It's important that the file gets rejected due to too big integer encoding instead of due to Uncompressed Size not matching the value stored in the Block Header. That is, the decoder must not try to decode the Compressed Data field. bad-1-vli-2.xz has ten-byte variable-length integer as Uncompressed Size in Block Header. It's important that the file gets rejected due to too big integer encoding instead of due to Uncompressed Size not matching the value stored in the Block Header. That is, the decoder must not try to decode the Compressed Data field. bad-1-block_header-1.xz has Block Header that ends in the middle of the Filter Flags field. bad-1-block_header-2.xz has Block Header that has Compressed Size and Uncompressed Size but no List of Filter Flags field. bad-1-block_header-3.xz has wrong CRC32 in Block Header. bad-1-block_header-4.xz has too big Compressed Size in Block Header (2^63 - 1 bytes while maximum is a little less, because the whole Block must stay smaller than 2^63). It's important that the file gets rejected due to invalid Compressed Size value; the decoder must not try decoding the Compressed Data field. bad-1-block_header-5.xz has zero as Compressed Size in Block Header. bad-1-block_header-6.xz has corrupt Block Header which may crash xz -lvv in XZ Utils 5.0.3 and earlier. It was fixed in the commit c0297445064951807803457dca1611b3c47e7f0f. bad-2-index-1.xz has wrong Unpadded Sizes in Index. bad-2-index-2.xz has wrong Uncompressed Sizes in Index. bad-2-index-3.xz has non-null byte in Index Padding. bad-2-index-4.xz wrong CRC32 in Index. bad-2-index-5.xz has zero as Unpadded Size. It is important that the file gets rejected specifically due to Unpadded Size having an invalid value. bad-2-compressed_data_padding.xz has non-null byte in the padding of the Compressed Data field of the first Block. bad-1-check-crc32.xz has wrong Check (CRC32). bad-1-check-crc64.xz has wrong Check (CRC64). bad-1-check-sha256.xz has wrong Check (SHA-256). bad-1-lzma2-1.xz has LZMA2 stream whose first chunk (uncompressed) doesn't reset the dictionary. bad-1-lzma2-2.xz has two LZMA2 chunks, of which the second chunk indicates dictionary reset, but the LZMA compressed data tries to repeat data from the previous chunk. bad-1-lzma2-3.xz sets new invalid properties (lc=8, lp=0, pb=0) in the middle of Block. bad-1-lzma2-4.xz has two LZMA2 chunks, of which the first is uncompressed and the second is LZMA. The first chunk resets dictionary as it should, but the second chunk tries to reset state without specifying properties for LZMA. bad-1-lzma2-5.xz is like bad-1-lzma2-4.xz but doesn't try to reset anything in the header of the second chunk. bad-1-lzma2-6.xz has reserved LZMA2 control byte value (0x03). bad-1-lzma2-7.xz has EOPM at LZMA level. bad-1-lzma2-8.xz is like good-1-lzma2-4.xz but doesn't set new properties in the third LZMA2 chunk. xz-5.1.3alpha/tests/files/bad-0-backward_size.xz0000644000000000000000000000004012232714400016363 000000000000007zXZi"6D!5YZxz-5.1.3alpha/tests/files/bad-0-empty-truncated.xz0000644000000000000000000000003712232714400016706 000000000000007zXZi"6D!B Yxz-5.1.3alpha/tests/files/bad-0-footer_magic.xz0000644000000000000000000000004012232714400016211 000000000000007zXZi"6D!B YXxz-5.1.3alpha/tests/files/bad-0-header_magic.xz0000644000000000000000000000004012232714400016143 000000000000007zXYi"6D!B YZxz-5.1.3alpha/tests/files/bad-0-nonempty_index.xz0000644000000000000000000000004012232714400016613 000000000000007zXZi"6+ B YZxz-5.1.3alpha/tests/files/bad-0cat-alone.xz0000644000000000000000000000006712232714400015352 000000000000007zXZi"6D!B YZ]xz-5.1.3alpha/tests/files/bad-0cat-header_magic.xz0000644000000000000000000000010012232714400016630 000000000000007zXZi"6D!B YZ7zXYi"6D!B YZxz-5.1.3alpha/tests/files/bad-0catpad-empty.xz0000644000000000000000000000010512232714400016070 000000000000007zXZi"6D!B YZ7zXZi"6D!B YZxz-5.1.3alpha/tests/files/bad-0pad-empty.xz0000644000000000000000000000004512232714400015403 000000000000007zXZi"6D!B YZxz-5.1.3alpha/tests/files/bad-1-block_header-1.xz0000644000000000000000000000010012232714400016311 000000000000007zXZi"6! `bHello World!

The check for device and inode numbers is there, because #. it is possible that the user has put a new file in place #. of the original file, and in that case it obviously #. shouldn't be removed. #: src/xz/file_io.c:236 #, c-format msgid "%s: File seems to have been moved, not removing" msgstr "" #: src/xz/file_io.c:243 src/xz/file_io.c:761 #, c-format msgid "%s: Cannot remove: %s" msgstr "" #: src/xz/file_io.c:268 #, c-format msgid "%s: Cannot set the file owner: %s" msgstr "" #: src/xz/file_io.c:274 #, c-format msgid "%s: Cannot set the file group: %s" msgstr "" #: src/xz/file_io.c:293 #, c-format msgid "%s: Cannot set the file permissions: %s" msgstr "" #: src/xz/file_io.c:399 #, c-format msgid "Error getting the file status flags from standard input: %s" msgstr "" #: src/xz/file_io.c:408 #, c-format msgid "Error setting O_NONBLOCK on standard input: %s" msgstr "" #: src/xz/file_io.c:460 src/xz/file_io.c:522 #, c-format msgid "%s: Is a symbolic link, skipping" msgstr "" #: src/xz/file_io.c:551 #, c-format msgid "%s: Is a directory, skipping" msgstr "" #: src/xz/file_io.c:557 #, c-format msgid "%s: Not a regular file, skipping" msgstr "" #: src/xz/file_io.c:574 #, c-format msgid "%s: File has setuid or setgid bit set, skipping" msgstr "" #: src/xz/file_io.c:581 #, c-format msgid "%s: File has sticky bit set, skipping" msgstr "" #: src/xz/file_io.c:588 #, c-format msgid "%s: Input file has more than one hard link, skipping" msgstr "" #: src/xz/file_io.c:668 #, c-format msgid "Error restoring the status flags to standard input: %s" msgstr "" #: src/xz/file_io.c:714 #, c-format msgid "Error getting the file status flags from standard output: %s" msgstr "" #: src/xz/file_io.c:723 #, c-format msgid "Error setting O_NONBLOCK on standard output: %s" msgstr "" #: src/xz/file_io.c:896 #, c-format msgid "Error restoring the O_APPEND flag to standard output: %s" msgstr "" #: src/xz/file_io.c:908 #, c-format msgid "%s: Closing the file failed: %s" msgstr "" #: src/xz/file_io.c:944 src/xz/file_io.c:1170 #, c-format msgid "%s: Seeking failed when trying to create a sparse file: %s" msgstr "" #: src/xz/file_io.c:1039 #, c-format msgid "%s: Read error: %s" msgstr "" #: src/xz/file_io.c:1059 #, c-format msgid "%s: Error seeking the file: %s" msgstr "" #: src/xz/file_io.c:1069 #, c-format msgid "%s: Unexpected end of file" msgstr "" #: src/xz/file_io.c:1128 #, c-format msgid "%s: Write error: %s" msgstr "" #: src/xz/hardware.c:101 msgid "Disabled" msgstr "" #.

The check for device and inode numbers is there, because #. it is possible that the user has put a new file in place #. of the original file, and in that case it obviously #. shouldn't be removed. #: src/xz/file_io.c:236 #, c-format msgid "%s: File seems to have been moved, not removing" msgstr "%s: sembra che il file sia stato spostato, non viene rimosso" #: src/xz/file_io.c:243 src/xz/file_io.c:761 #, c-format msgid "%s: Cannot remove: %s" msgstr "%s: impossibile rimuovere: %s" #: src/xz/file_io.c:268 #, c-format msgid "%s: Cannot set the file owner: %s" msgstr "%s: impossibile impostare il proprietario del file: %s" #: src/xz/file_io.c:274 #, c-format msgid "%s: Cannot set the file group: %s" msgstr "%s: impossibile impostare il gruppo del file: %s" #: src/xz/file_io.c:293 #, c-format msgid "%s: Cannot set the file permissions: %s" msgstr "%s: impossibile impostare i permessi del file: %s" #: src/xz/file_io.c:399 #, fuzzy, c-format msgid "Error getting the file status flags from standard input: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:408 #, fuzzy, c-format msgid "Error setting O_NONBLOCK on standard input: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:460 src/xz/file_io.c:522 #, c-format msgid "%s: Is a symbolic link, skipping" msgstr "%s: è un collegamento simbolico, viene saltato" #: src/xz/file_io.c:551 #, c-format msgid "%s: Is a directory, skipping" msgstr "%s: è una directory, viene saltata" #: src/xz/file_io.c:557 #, c-format msgid "%s: Not a regular file, skipping" msgstr "%s: non è un file regolare, viene saltato" #: src/xz/file_io.c:574 #, c-format msgid "%s: File has setuid or setgid bit set, skipping" msgstr "%s: il file ha il bit setuid o setgid impostato, viene saltato" #: src/xz/file_io.c:581 #, c-format msgid "%s: File has sticky bit set, skipping" msgstr "%s: il file ha lo sticky bit impostato, viene saltato" #: src/xz/file_io.c:588 #, c-format msgid "%s: Input file has more than one hard link, skipping" msgstr "%s: il file di input ha più di un collegamento fisico, viene saltato" #: src/xz/file_io.c:668 #, fuzzy, c-format msgid "Error restoring the status flags to standard input: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:714 #, fuzzy, c-format msgid "Error getting the file status flags from standard output: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:723 #, fuzzy, c-format msgid "Error setting O_NONBLOCK on standard output: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:896 #, c-format msgid "Error restoring the O_APPEND flag to standard output: %s" msgstr "Errore nel ripristinare la flag O_APPEND sullo standard output: %s" #: src/xz/file_io.c:908 #, c-format msgid "%s: Closing the file failed: %s" msgstr "%s: chiusura del file non riuscita: %s" #: src/xz/file_io.c:944 src/xz/file_io.c:1170 #, c-format msgid "%s: Seeking failed when trying to create a sparse file: %s" msgstr "%s: posizionamento non riuscito nel tentativo di creare un file sparso: %s" #: src/xz/file_io.c:1039 #, c-format msgid "%s: Read error: %s" msgstr "%s: errore di lettura: %s" #: src/xz/file_io.c:1059 #, c-format msgid "%s: Error seeking the file: %s" msgstr "%s: errore nel cercare il file: %s" #: src/xz/file_io.c:1069 #, c-format msgid "%s: Unexpected end of file" msgstr "%s: fine del file inaspettata" #: src/xz/file_io.c:1128 #, c-format msgid "%s: Write error: %s" msgstr "%s: errore di scrittura: %s" #: src/xz/hardware.c:101 msgid "Disabled" msgstr "Disabilitato" #.

The check for device and inode numbers is there, because #. it is possible that the user has put a new file in place #. of the original file, and in that case it obviously #. shouldn't be removed. #: src/xz/file_io.c:236 #, c-format msgid "%s: File seems to have been moved, not removing" msgstr "%s: Vypadá to, že soubor byl přesunut, proto nebude odstraněn" #: src/xz/file_io.c:243 src/xz/file_io.c:761 #, c-format msgid "%s: Cannot remove: %s" msgstr "%s: Nelze odstranit: %s" #: src/xz/file_io.c:268 #, c-format msgid "%s: Cannot set the file owner: %s" msgstr "%s: Nelze nastavit vlastníka souboru: %s" #: src/xz/file_io.c:274 #, c-format msgid "%s: Cannot set the file group: %s" msgstr "%s: Nelze nastavit skupinu souboru: %s" #: src/xz/file_io.c:293 #, c-format msgid "%s: Cannot set the file permissions: %s" msgstr "%s: Nelze nastavit oprávnění souboru: %s" #: src/xz/file_io.c:399 #, fuzzy, c-format msgid "Error getting the file status flags from standard input: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:408 #, fuzzy, c-format msgid "Error setting O_NONBLOCK on standard input: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:460 src/xz/file_io.c:522 #, c-format msgid "%s: Is a symbolic link, skipping" msgstr "%s: Jedná se o symbolický odkaz, vynechává se" #: src/xz/file_io.c:551 #, c-format msgid "%s: Is a directory, skipping" msgstr "%s: Jedná se o složku, vynechává se" #: src/xz/file_io.c:557 #, c-format msgid "%s: Not a regular file, skipping" msgstr "%s: Nejedná se o běžný soubor, vynechává se" #: src/xz/file_io.c:574 #, c-format msgid "%s: File has setuid or setgid bit set, skipping" msgstr "%s: Soubor má nastavený bit setuid nebo setgid, vynechává se" #: src/xz/file_io.c:581 #, c-format msgid "%s: File has sticky bit set, skipping" msgstr "%s: Soubor má nastavený bit sticky, vynechává se" #: src/xz/file_io.c:588 #, c-format msgid "%s: Input file has more than one hard link, skipping" msgstr "%s: Vstupní soubor má více než jeden pevný odkaz, vynechává se" #: src/xz/file_io.c:668 #, fuzzy, c-format msgid "Error restoring the status flags to standard input: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:714 #, fuzzy, c-format msgid "Error getting the file status flags from standard output: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:723 #, fuzzy, c-format msgid "Error setting O_NONBLOCK on standard output: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:896 #, c-format msgid "Error restoring the O_APPEND flag to standard output: %s" msgstr "Chyba při obnovení příznaku O_APPEND na standardní výstup: %s" #: src/xz/file_io.c:908 #, c-format msgid "%s: Closing the file failed: %s" msgstr "%s: Selhalo zavření souboru: %s" #: src/xz/file_io.c:944 src/xz/file_io.c:1170 #, c-format msgid "%s: Seeking failed when trying to create a sparse file: %s" msgstr "%s: Selhalo nastavení pozice při pokusu o vytvoření souboru řídké matice: %s" #: src/xz/file_io.c:1039 #, c-format msgid "%s: Read error: %s" msgstr "%s: Chyba čtení: %s" #: src/xz/file_io.c:1059 #, c-format msgid "%s: Error seeking the file: %s" msgstr "%s: Chyba při posunu v rámci souboru: %s" #: src/xz/file_io.c:1069 #, c-format msgid "%s: Unexpected end of file" msgstr "%s: Neočekávaný konec souboru" #: src/xz/file_io.c:1128 #, c-format msgid "%s: Write error: %s" msgstr "%s: Chyba zápisu: %s" #: src/xz/hardware.c:101 msgid "Disabled" msgstr "Vypnuto" #.

It reads the first 13 bytes from the specified .IR file , decodes the header, and prints it to standard output in human readable format. If no .I files are given or .I file is .BR \- , standard input is read. .PP Usually the most interesting information is the uncompressed size and the dictionary size. Uncompressed size can be shown only if the file is in the non-streamed .B .lzma format variant. The amount of memory required to decompress the file is a few dozen kilobytes plus the dictionary size. .PP .B lzmainfo is included in XZ Utils primarily for backward compatibility with LZMA Utils. .SH "EXIT STATUS" .TP .B 0 All is good. .TP .B 1 An error occurred. .SH BUGS .B lzmainfo uses .B MB while the correct suffix would be .B MiB (2^20 bytes). This is to keep the output compatible with LZMA Utils. .SH "SEE ALSO" .BR xz (1) xz-5.1.3alpha/src/lzmainfo/Makefile.am0000644000000000000000000000146112232714400014515 00000000000000## ## Author: Lasse Collin ## ## This file has been put into the public domain. ## You can do whatever you want with this file. ## bin_PROGRAMS = lzmainfo lzmainfo_SOURCES = \ lzmainfo.c \ $(top_srcdir)/src/common/tuklib_progname.c \ $(top_srcdir)/src/common/tuklib_exit.c if COND_W32 lzmainfo_SOURCES += lzmainfo_w32res.rc endif lzmainfo_CPPFLAGS = \ -DLOCALEDIR=\"$(localedir)\" \ -I$(top_srcdir)/src/common \ -I$(top_srcdir)/src/liblzma/api \ -I$(top_builddir)/lib lzmainfo_LDADD = $(top_builddir)/src/liblzma/liblzma.la if COND_GNULIB lzmainfo_LDADD += $(top_builddir)/lib/libgnu.a endif lzmainfo_LDADD += $(LTLIBINTL) dist_man_MANS = lzmainfo.1 # Windows resource compiler support .rc.o: $(RC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) \ $(lzmainfo_CPPFLAGS) $(CPPFLAGS) $(RCFLAGS) -i $< -o $@ xz-5.1.3alpha/src/lzmainfo/Makefile.in0000644000000000000000000007503112232714504014537 00000000000000# Makefile.in generated by automake 1.14 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2013 Free Software Foundation, Inc. # This Makefile.in is free software;

The native file format is the .B .xz format, but the legacy .B .lzma format used by LZMA Utils and raw compressed streams with no container format headers are also supported. .PP .B xz compresses or decompresses each .I file according to the selected operation mode. If no .I files are given or .I file is .BR \- , .B xz reads from standard input and writes the processed data to standard output. .B xz will refuse (display an error and skip the .IR file ) to write compressed data to standard output if it is a terminal. Similarly, .B xz will refuse to read compressed data from standard input if it is a terminal. .PP Unless .B \-\-stdout is specified, .I files other than .B \- are written to a new file whose name is derived from the source .I file name: .IP \(bu 3 When compressing, the suffix of the target file format .RB ( .xz or .BR .lzma ) is appended to the source filename to get the target filename. .IP \(bu 3 When decompressing, the .B .xz or .B .lzma suffix is removed from the filename to get the target filename. .B xz also recognizes the suffixes .B .txz and .BR .tlz , and replaces them with the .B .tar suffix. .PP If the target file already exists, an error is displayed and the .I file is skipped. .PP Unless writing to standard output, .B xz will display a warning and skip the .I file if any of the following applies: .IP \(bu 3 .I File is not a regular file. Symbolic links are not followed, and thus they are not considered to be regular files. .IP \(bu 3 .I File has more than one hard link. .IP \(bu 3 .I File has setuid, setgid, or sticky bit set. .IP \(bu 3 The operation mode is set to compress and the .I file already has a suffix of the target file format .RB ( .xz or .B .txz when compressing to the .B .xz format, and .B .lzma or .B .tlz when compressing to the .B .lzma format). .IP \(bu 3 The operation mode is set to decompress and the .I file doesn't have a suffix of any of the supported file formats .RB ( .xz , .BR .txz , .BR .lzma , or .BR .tlz ). .PP After successfully compressing or decompressing the .IR file , .B xz copies the owner, group, permissions, access time, and modification time from the source .I file to the target file. If copying the group fails, the permissions are modified so that the target file doesn't become accessible to users who didn't have permission to access the source .IR file . .B xz doesn't support copying other metadata like access control lists or extended attributes yet. .PP Once the target file has been successfully closed, the source .I file is removed unless .B \-\-keep was specified. The source .I file is never removed if the output is written to standard output. .PP Sending .B SIGINFO or .B SIGUSR1 to the .B xz process makes it print progress information to standard error. This has only limited use since when standard error is a terminal, using .B \-\-verbose will display an automatically updating progress indicator. . .SS "Memory usage" The memory usage of .B xz varies from a few hundred kilobytes to several gigabytes depending on the compression settings. The settings used when compressing a file determine the memory requirements of the decompressor. Typically the decompressor needs 5\ % to 20\ % of the amount of memory that the compressor needed when creating the file. For example, decompressing a file created with .B xz \-9 currently requires 65\ MiB of memory. Still, it is possible to have .B .xz files that require several gigabytes of memory to decompress. .PP Especially users of older systems may find the possibility of very large memory usage annoying. To prevent uncomfortable surprises, .B xz has a built-in memory usage limiter, which is disabled by default. While some operating systems provide ways to limit the memory usage of processes, relying on it wasn't deemed to be flexible enough (e.g. using .BR ulimit (1) to limit virtual memory tends to cripple .BR mmap (2)). .PP The memory usage limiter can be enabled with the command line option \fB\-\-memlimit=\fIlimit\fR. Often it is more convenient to enable the limiter by default by setting the environment variable .BR XZ_DEFAULTS , e.g.\& .BR XZ_DEFAULTS=\-\-memlimit=150MiB . It is possible to set the limits separately for compression and decompression by using \fB\-\-memlimit\-compress=\fIlimit\fR and \fB\-\-memlimit\-decompress=\fIlimit\fR. Using these two options outside .B XZ_DEFAULTS is rarely useful because a single run of .B xz cannot do both compression and decompression and .BI \-\-memlimit= limit (or \fB\-M\fR \fIlimit\fR) is shorter to type on the command line. .PP If the specified memory usage limit is exceeded when decompressing, .B xz will display an error and decompressing the file will fail. If the limit is exceeded when compressing, .B xz will try to scale the settings down so that the limit is no longer exceeded (except when using \fB\-\-format=raw\fR or \fB\-\-no\-adjust\fR). This way the operation won't fail unless the limit is very small. The scaling of the settings is done in steps that don't match the compression level presets, e.g. if the limit is only slightly less than the amount required for .BR "xz \-9" , the settings will be scaled down only a little, not all the way down to .BR "xz \-8" . . .SS "Concatenation and padding with .xz files" It is possible to concatenate .B .xz files as is. .B xz will decompress such files as if they were a single .B .xz file. .PP It is possible to insert padding between the concatenated parts or after the last part. The padding must consist of null bytes and the size of the padding must be a multiple of four bytes. This can be useful e.g. if the .B .xz file is stored on a medium that measures file sizes in 512-byte blocks. .PP Concatenation and padding are not allowed with .B .lzma files or raw streams. . .SH OPTIONS . .SS "Integer suffixes and special values" In most places where an integer argument is expected, an optional suffix is supported to easily indicate large integers. There must be no space between the integer and the suffix. .TP .B KiB Multiply the integer by 1,024 (2^10). .BR Ki , .BR k , .BR kB , .BR K , and .B KB are accepted as synonyms for .BR KiB . .TP .B MiB Multiply the integer by 1,048,576 (2^20). .BR Mi , .BR m , .BR M , and .B MB are accepted as synonyms for .BR MiB . .TP .B GiB Multiply the integer by 1,073,741,824 (2^30). .BR Gi , .BR g , .BR G , and .B GB are accepted as synonyms for .BR GiB . .PP The special value .B max can be used to indicate the maximum integer value supported by the option. . .SS "Operation mode" If multiple operation mode options are given, the last one takes effect. .TP .BR \-z ", " \-\-compress Compress.

When a custom filter chain is specified, preset options (\fB\-0\fR ... \fB\-9\fR and \fB\-\-extreme\fR) earlier on the command line are forgotten. If a preset option is specified after one or more custom filter chain options, the new preset takes effect and the custom filter chain options specified earlier are forgotten. .PP A filter chain is comparable to piping on the command line. When compressing, the uncompressed input goes to the first filter, whose output goes to the next filter (if any). The output of the last filter gets written to the compressed file. The maximum number of filters in the chain is four, but typically a filter chain has only one or two filters. .PP Many filters have limitations on where they can be in the filter chain: some filters can work only as the last filter in the chain, some only as a non-last filter, and some work in any position in the chain. Depending on the filter, this limitation is either inherent to the filter design or exists to prevent security issues. .PP A custom filter chain is specified by using one or more filter options in the order they are wanted in the filter chain. That is, the order of filter options is significant! When decoding raw streams .RB ( \-\-format=raw ), the filter chain is specified in the same order as it was specified when compressing. .PP Filters take filter-specific .I options as a comma-separated list. Extra commas in .I options are ignored. Every option has a default value, so you need to specify only those you want to change. .PP To see the whole filter chain and .IR options , use .B "xz \-vv" (that is, use .B \-\-verbose twice). This works also for viewing the filter chain options used by presets. .TP \fB\-\-lzma1\fR[\fB=\fIoptions\fR] .PD 0 .TP \fB\-\-lzma2\fR[\fB=\fIoptions\fR] .PD Add LZMA1 or LZMA2 filter to the filter chain. These filters can be used only as the last filter in the chain. .IP "" LZMA1 is a legacy filter, which is supported almost solely due to the legacy .B .lzma file format, which supports only LZMA1. LZMA2 is an updated version of LZMA1 to fix some practical issues of LZMA1. The .B .xz format uses LZMA2 and doesn't support LZMA1 at all. Compression speed and ratios of LZMA1 and LZMA2 are practically the same. .IP "" LZMA1 and LZMA2 share the same set of .IR options : .RS .TP .BI preset= preset Reset all LZMA1 or LZMA2 .I options to .IR preset . .I Preset consist of an integer, which may be followed by single-letter preset modifiers. The integer can be from .B 0 to .BR 9 , matching the command line options \fB\-0\fR ... \fB\-9\fR. The only supported modifier is currently .BR e , which matches .BR \-\-extreme . If no .B preset is specified, the default values of LZMA1 or LZMA2 .I options are taken from the preset .BR 6 . .TP .BI dict= size Dictionary (history buffer) .I size indicates how many bytes of the recently processed uncompressed data is kept in memory. The algorithm tries to find repeating byte sequences (matches) in the uncompressed data, and replace them with references to the data currently in the dictionary. The bigger the dictionary, the higher is the chance to find a match. Thus, increasing dictionary .I size usually improves compression ratio, but a dictionary bigger than the uncompressed file is waste of memory. .IP "" Typical dictionary .I size is from 64\ KiB to 64\ MiB. The minimum is 4\ KiB. The maximum for compression is currently 1.5\ GiB (1536\ MiB). The decompressor already supports dictionaries up to one byte less than 4\ GiB, which is the maximum for the LZMA1 and LZMA2 stream formats. .IP "" Dictionary .I size and match finder .RI ( mf ) together determine the memory usage of the LZMA1 or LZMA2 encoder. The same (or bigger) dictionary .I size is required for decompressing that was used when compressing, thus the memory usage of the decoder is determined by the dictionary size used when compressing. The .B .xz headers store the dictionary .I size either as .RI "2^" n or .RI "2^" n " + 2^(" n "\-1)," so these .I sizes are somewhat preferred for compression. Other .I sizes will get rounded up when stored in the .B .xz headers. .TP .BI lc= lc Specify the number of literal context bits. The minimum is 0 and the maximum is 4; the default is 3. In addition, the sum of .I lc and .I lp must not exceed 4. .IP "" All bytes that cannot be encoded as matches are encoded as literals. That is, literals are simply 8-bit bytes that are encoded one at a time. .IP "" The literal coding makes an assumption that the highest .I lc bits of the previous uncompressed byte correlate with the next byte. E.g. in typical English text, an upper-case letter is often followed by a lower-case letter, and a lower-case letter is usually followed by another lower-case letter. In the US-ASCII character set, the highest three bits are 010 for upper-case letters and 011 for lower-case letters. When .I lc is at least 3, the literal coding can take advantage of this property in the uncompressed data. .IP "" The default value (3) is usually good. If you want maximum compression, test .BR lc=4 . Sometimes it helps a little, and sometimes it makes compression worse. If it makes it worse, test e.g.\& .B lc=2 too. .TP .BI lp= lp Specify the number of literal position bits. The minimum is 0 and the maximum is 4; the default is 0. .IP "" .I Lp affects what kind of alignment in the uncompressed data is assumed when encoding literals. See .I pb below for more information about alignment. .TP .BI pb= pb Specify the number of position bits. The minimum is 0 and the maximum is 4; the default is 2. .IP "" .I Pb affects what kind of alignment in the uncompressed data is assumed in general. The default means four-byte alignment .RI (2^ pb =2^2=4), which is often a good choice when there's no better guess. .IP "" When the aligment is known, setting .I pb accordingly may reduce the file size a little. E.g. with text files having one-byte alignment (US-ASCII, ISO-8859-*, UTF-8), setting .B pb=0 can improve compression slightly. For UTF-16 text, .B pb=1 is a good choice. If the alignment is an odd number like 3 bytes, .B pb=0 might be the best choice. .IP "" Even though the assumed alignment can be adjusted with .I pb and .IR lp , LZMA1 and LZMA2 still slightly favor 16-byte alignment. It might be worth taking into account when designing file formats that are likely to be often compressed with LZMA1 or LZMA2. .TP .BI mf= mf Match finder has a major effect on encoder speed, memory usage, and compression ratio.

Level;xz;LZMA Utils \-0;256 KiB;N/A \-1;1 MiB;64 KiB \-2;2 MiB;1 MiB \-3;4 MiB;512 KiB \-4;4 MiB;1 MiB \-5;8 MiB;2 MiB \-6;8 MiB;4 MiB \-7;16 MiB;8 MiB \-8;32 MiB;16 MiB \-9;64 MiB;32 MiB .TE .RE .PP The dictionary size differences affect the compressor memory usage too, but there are some other differences between LZMA Utils and XZ Utils, which make the difference even bigger: .RS .PP .TS tab(;); c c c c n n. Level;xz;LZMA Utils 4.32.x \-0;3 MiB;N/A \-1;9 MiB;2 MiB \-2;17 MiB;12 MiB \-3;32 MiB;12 MiB \-4;48 MiB;16 MiB \-5;94 MiB;26 MiB \-6;94 MiB;45 MiB \-7;186 MiB;83 MiB \-8;370 MiB;159 MiB \-9;674 MiB;311 MiB .TE .RE .PP The default preset level in LZMA Utils is .B \-7 while in XZ Utils it is .BR \-6 , so both use an 8 MiB dictionary by default. . .SS "Streamed vs. non-streamed .lzma files" The uncompressed size of the file can be stored in the .B .lzma header. LZMA Utils does that when compressing regular files. The alternative is to mark that uncompressed size is unknown and use end-of-payload marker to indicate where the decompressor should stop. LZMA Utils uses this method when uncompressed size isn't known, which is the case for example in pipes. .PP .B xz supports decompressing .B .lzma files with or without end-of-payload marker, but all .B .lzma files created by .B xz will use end-of-payload marker and have uncompressed size marked as unknown in the .B .lzma header. This may be a problem in some uncommon situations. For example, a .B .lzma decompressor in an embedded device might work only with files that have known uncompressed size. If you hit this problem, you need to use LZMA Utils or LZMA SDK to create .B .lzma files with known uncompressed size. . .SS "Unsupported .lzma files" The .B .lzma format allows .I lc values up to 8, and .I lp values up to 4. LZMA Utils can decompress files with any .I lc and .IR lp , but always creates files with .B lc=3 and .BR lp=0 . Creating files with other .I lc and .I lp is possible with .B xz and with LZMA SDK. .PP The implementation of the LZMA1 filter in liblzma requires that the sum of .I lc and .I lp must not exceed 4. Thus, .B .lzma files, which exceed this limitation, cannot be decompressed with .BR xz . .PP LZMA Utils creates only .B .lzma files which have a dictionary size of .RI "2^" n (a power of 2) but accepts files with any dictionary size. liblzma accepts only .B .lzma files which have a dictionary size of .RI "2^" n or .RI "2^" n " + 2^(" n "\-1)." This is to decrease false positives when detecting .B .lzma files. .PP These limitations shouldn't be a problem in practice, since practically all .B .lzma files have been compressed with settings that liblzma will accept. . .SS "Trailing garbage" When decompressing, LZMA Utils silently ignore everything after the first .B .lzma stream. In most situations, this is a bug. This also means that LZMA Utils don't support decompressing concatenated .B .lzma files. .PP If there is data left after the first .B .lzma stream, .B xz considers the file to be corrupt unless .B \-\-single\-stream was used. This may break obscure scripts which have assumed that trailing garbage is ignored. . .SH NOTES . .SS "Compressed output may vary" The exact compressed output produced from the same uncompressed input file may vary between XZ Utils versions even if compression options are identical. This is because the encoder can be improved (faster or better compression) without affecting the file format. The output can vary even between different builds of the same XZ Utils version, if different build options are used. .PP The above means that once .B \-\-rsyncable has been implemented, the resulting files won't necessarily be rsyncable unless both old and new files have been compressed with the same xz version. This problem can be fixed if a part of the encoder implementation is frozen to keep rsyncable output stable across xz versions. . .SS "Embedded .xz decompressors" Embedded .B .xz decompressor implementations like XZ Embedded don't necessarily support files created with integrity .I check types other than .B none and .BR crc32 . Since the default is .BR \-\-check=crc64 , you must use .B \-\-check=none or .B \-\-check=crc32 when creating files for embedded systems. .PP Outside embedded systems, all .B .xz format decompressors support all the .I check types, or at least are able to decompress the file without verifying the integrity check if the particular .I check is not supported. .PP XZ Embedded supports BCJ filters, but only with the default start offset. . .SH EXAMPLES . .SS Basics Compress the file .I foo into .I foo.xz using the default compression level .RB ( \-6 ), and remove .I foo if compression is successful: .RS .PP .nf .ft CW xz foo .ft R .fi .RE .PP Decompress .I bar.xz into .I bar and don't remove .I bar.xz even if decompression is successful: .RS .PP .nf .ft CW xz \-dk bar.xz .ft R .fi .RE .PP Create .I baz.tar.xz with the preset .B \-4e .RB ( "\-4 \-\-extreme" ), which is slower than e.g. the default .BR \-6 , but needs less memory for compression and decompression (48\ MiB and 5\ MiB, respectively): .RS .PP .nf .ft CW tar cf \- baz | xz \-4e > baz.tar.xz .ft R .fi .RE .PP A mix of compressed and uncompressed files can be decompressed to standard output with a single command: .RS .PP .nf .ft CW xz \-dcf a.txt b.txt.xz c.txt d.txt.lzma > abcd.txt .ft R .fi .RE . .SS "Parallel compression of many files" On GNU and *BSD, .BR find (1) and .BR xargs (1) can be used to parallelize compression of many files: .RS .PP .nf .ft CW find . \-type f \e! \-name '*.xz' \-print0 \e | xargs \-0r \-P4 \-n16 xz \-T1 .ft R .fi .RE .PP The .B \-P option to .BR xargs (1) sets the number of parallel .B xz processes. The best value for the .B \-n option depends on how many files there are to be compressed. If there are only a couple of files, the value should probably be 1; with tens of thousands of files, 100 or even more may be appropriate to reduce the number of .B xz processes that .BR xargs (1) will eventually create. .PP The option .B \-T1 for .B xz is there to force it to single-threaded mode, because .BR xargs (1) is used to control the amount of parallelization. . .SS "Robot mode" Calculate how many bytes have been saved in total after compressing multiple files: .RS .PP .nf .ft CW xz \-\-robot \-\-list *.xz | awk '/^totals/{print $5\-$4}' .ft R .fi .RE .PP A script may want to know that it is using new enough .BR xz . The following .BR sh (1) script checks that the version number of the .B xz tool is at least 5.0.0. This method is compatible with old beta versions, which didn't support the .B \-\-robot option: .RS .PP .nf .ft CW if ! eval "$(xz \-\-robot \-\-version 2> /dev/null)" || [ "$XZ_VERSION" \-lt 50000002 ]; then echo "Your xz is too old." fi unset XZ_VERSION LIBLZMA_VERSION .ft R .fi .RE .PP Set a memory usage limit for decompression using .BR XZ_OPT , but if a limit has already been set, don't increase it: .RS .PP .nf .ft CW NEWLIM=$((123 << 20)) # 123 MiB OLDLIM=$(xz \-\-robot \-\-info\-memory | cut \-f3) if [ $OLDLIM \-eq 0 \-o $OLDLIM \-gt $NEWLIM ]; then XZ_OPT="$XZ_OPT \-\-memlimit\-decompress=$NEWLIM" export XZ_OPT fi .ft R .fi .RE . .SS "Custom compressor filter chains" The simplest use for custom filter chains is customizing a LZMA2 preset. This can be useful, because the presets cover only a subset of the potentially useful combinations of compression settings. .PP The CompCPU columns of the tables from the descriptions of the options .BR "\-0" " ... " "\-9" and .B \-\-extreme are useful when customizing LZMA2 presets. Here are the relevant parts collected from those two tables: .RS .PP .TS tab(;); c c n n. Preset;CompCPU \-0;0 \-1;1 \-2;2 \-3;3 \-4;4 \-5;5 \-6;6 \-5e;7 \-6e;8 .TE .RE .PP If you know that a file requires somewhat big dictionary (e.g. 32 MiB) to compress well, but you want to compress it quicker than .B "xz \-8" would do, a preset with a low CompCPU value (e.g. 1) can be modified to use a bigger dictionary: .RS .PP .nf .ft CW xz \-\-lzma2=preset=1,dict=32MiB foo.tar .ft R .fi .RE .PP With certain files, the above command may be faster than .B "xz \-6" while compressing significantly better. However, it must be emphasized that only some files benefit from a big dictionary while keeping the CompCPU value low. The most obvious situation, where a big dictionary can help a lot, is an archive containing very similar files of at least a few megabytes each. The dictionary size has to be significantly bigger than any individual file to allow LZMA2 to take full advantage of the similarities between consecutive files. .PP If very high compressor and decompressor memory usage is fine, and the file being compressed is at least several hundred megabytes, it may be useful to use an even bigger dictionary than the 64 MiB that .B "xz \-9" would use: .RS .PP .nf .ft CW xz \-vv \-\-lzma2=dict=192MiB big_foo.tar .ft R .fi .RE .PP Using .B \-vv .RB ( "\-\-verbose \-\-verbose" ) like in the above example can be useful to see the memory requirements of the compressor and decompressor. Remember that using a dictionary bigger than the size of the uncompressed file is waste of memory, so the above command isn't useful for small files. .PP Sometimes the compression time doesn't matter, but the decompressor memory usage has to be kept low e.g. to make it possible to decompress the file on an embedded system. The following command uses .B \-6e .RB ( "\-6 \-\-extreme" ) as a base and sets the dictionary to only 64\ KiB. The resulting file can be decompressed with XZ Embedded (that's why there is .BR \-\-check=crc32 ) using about 100\ KiB of memory. .RS .PP .nf .ft CW xz \-\-check=crc32 \-\-lzma2=preset=6e,dict=64KiB foo .ft R .fi .RE .PP If you want to squeeze out as many bytes as possible, adjusting the number of literal context bits .RI ( lc ) and number of position bits .RI ( pb ) can sometimes help. Adjusting the number of literal position bits .RI ( lp ) might help too, but usually .I lc and .I pb are more important. E.g. a source code archive contains mostly US-ASCII text, so something like the following might give slightly (like 0.1\ %) smaller file than .B "xz \-6e" (try also without .BR lc=4 ): .RS .PP .nf .ft CW xz \-\-lzma2=preset=6e,pb=0,lc=4 source_code.tar .ft R .fi .RE .PP Using another filter together with LZMA2 can improve compression with certain file types. E.g. to compress a x86-32 or x86-64 shared library using the x86 BCJ filter: .RS .PP .nf .ft CW xz \-\-x86 \-\-lzma2 libfoo.so .ft R .fi .RE .PP Note that the order of the filter options is significant. If .B \-\-x86 is specified after .BR \-\-lzma2 , .B xz will give an error, because there cannot be any filter after LZMA2, and also because the x86 BCJ filter cannot be used as the last filter in the chain. .PP The Delta filter together with LZMA2 can give good results with bitmap images. It should usually beat PNG, which has a few more advanced filters than simple delta but uses Deflate for the actual compression. .PP The image has to be saved in uncompressed format, e.g. as uncompressed TIFF. The distance parameter of the Delta filter is set to match the number of bytes per pixel in the image. E.g. 24-bit RGB bitmap needs .BR dist=3 , and it is also good to pass .B pb=0 to LZMA2 to accommodate the three-byte alignment: .RS .PP .nf .ft CW xz \-\-delta=dist=3 \-\-lzma2=pb=0 foo.tiff .ft R .fi .RE .PP If multiple images have been put into a single archive (e.g.\& .BR .tar ), the Delta filter will work on that too as long as all images have the same number of bytes per pixel. . .SH "SEE ALSO" .BR xzdec (1), .BR xzdiff (1), .BR xzgrep (1), .BR xzless (1), .BR xzmore (1), .BR gzip (1), .BR bzip2 (1), .BR 7z (1) .PP XZ Utils: .br XZ Embedded: .br LZMA SDK: xz-5.1.3alpha/src/xz/Makefile.am0000644000000000000000000000437112232714400013342 00000000000000## ## Author: Lasse Collin ## ## This file has been put into the public domain. ## You can do whatever you want with this file. ## bin_PROGRAMS = xz xz_SOURCES = \ args.c \ args.h \ coder.c \ coder.h \ file_io.c \ file_io.h \ hardware.c \ hardware.h \ list.c \ list.h \ main.c \ main.h \ message.c \ message.h \ mytime.c \ mytime.h \ options.c \ options.h \ private.h \ signals.c \ signals.h \ suffix.c \ suffix.h \ util.c \ util.h \ $(top_srcdir)/src/common/tuklib_open_stdxxx.c \ $(top_srcdir)/src/common/tuklib_progname.c \ $(top_srcdir)/src/common/tuklib_exit.c \ $(top_srcdir)/src/common/tuklib_cpucores.c \ $(top_srcdir)/src/common/tuklib_mbstr_width.c \ $(top_srcdir)/src/common/tuklib_mbstr_fw.c if COND_W32 xz_SOURCES += xz_w32res.rc endif xz_CPPFLAGS = \ -DLOCALEDIR=\"$(localedir)\" \ -I$(top_srcdir)/src/common \ -I$(top_srcdir)/src/liblzma/api \ -I$(top_builddir)/lib xz_LDADD = $(top_builddir)/src/liblzma/liblzma.la if COND_GNULIB xz_LDADD += $(top_builddir)/lib/libgnu.a endif # libgnu.a may need these libs, so this must be after libgnu.a. xz_LDADD += $(LTLIBINTL) # Windows resource compiler support .rc.o: $(RC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) \ $(xz_CPPFLAGS) $(CPPFLAGS) $(RCFLAGS) -i $< -o $@ dist_man_MANS = xz.1 ## Create symlinks for unxz and xzcat for convenience.

Specify this twice to suppress errors. .TP .BR \-Q ", " \-\-no-warn Ignored for .BR xz (1) compatibility. .B xzdec never uses the exit status 2. .TP .BR \-h ", " \-\-help Display a help message and exit successfully. .TP .BR \-V ", " \-\-version Display the version number of .B xzdec and liblzma. .SH "EXIT STATUS" .TP .B 0 All was good. .TP .B 1 An error occurred. .PP .B xzdec doesn't have any warning messages like .BR xz (1) has, thus the exit status 2 is not used by .BR xzdec . .SH NOTES Use .BR xz (1) instead of .B xzdec or .B lzmadec for normal everyday use. .B xzdec or .B lzmadec are meant only for situations where it is important to have a smaller decompressor than the full-featured .BR xz (1). .PP .B xzdec and .B lzmadec are not really that small. The size can be reduced further by dropping features from liblzma at compile time, but that shouldn't usually be done for executables distributed in typical non-embedded operating system distributions. If you need a truly small .B .xz decompressor, consider using XZ Embedded. .SH "SEE ALSO" .BR xz (1) .PP XZ Embedded: xz-5.1.3alpha/src/xzdec/Makefile.am0000644000000000000000000000305012232714400014007 00000000000000## ## Author: Lasse Collin ## ## This file has been put into the public domain. ## You can do whatever you want with this file. ## # Windows resource compiler support.

The native file format is .xz, but also the old .lzma * format and raw (no headers) streams are supported. Multiple compression * algorithms (filters) are supported. Currently LZMA2 is the primary filter. * * liblzma is part of XZ Utils . XZ Utils includes * a gzip-like command line tool named xz and some other tools. XZ Utils * is developed and maintained by Lasse Collin. * * Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK * . * * The SHA-256 implementation is based on the public domain code found from * 7-Zip , which has a modified version of the public * domain SHA-256 code found from Crypto++ . * The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai. */ /* * Author: Lasse Collin * * This file has been put into the public domain. * You can do whatever you want with this file. */ #ifndef LZMA_H #define LZMA_H /***************************** * Required standard headers * *****************************/ /* * liblzma API headers need some standard types and macros. To allow * including lzma.h without requiring the application to include other * headers first, lzma.h includes the required standard headers unless * they already seem to be included already or if LZMA_MANUAL_HEADERS * has been defined. * * Here's what types and macros are needed and from which headers: * - stddef.h: size_t, NULL * - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n), * UINT32_MAX, UINT64_MAX * * However, inttypes.h is a little more portable than stdint.h, although * inttypes.h declares some unneeded things compared to plain stdint.h. * * The hacks below aren't perfect, specifically they assume that inttypes.h * exists and that it typedefs at least uint8_t, uint32_t, and uint64_t, * and that, in case of incomplete inttypes.h, unsigned int is 32-bit. * If the application already takes care of setting up all the types and * macros properly (for example by using gnulib's stdint.h or inttypes.h), * we try to detect that the macros are already defined and don't include * inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to * force this file to never include any system headers. * * Some could argue that liblzma API should provide all the required types, * for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was * seen as an unnecessary mess, since most systems already provide all the * necessary types and macros in the standard headers. * * Note that liblzma API still has lzma_bool, because using stdbool.h would * break C89 and C++ programs on many systems. sizeof(bool) in C99 isn't * necessarily the same as sizeof(bool) in C++. */ #ifndef LZMA_MANUAL_HEADERS /* * I suppose this works portably also in C++.

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns -1. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call. If LONG_ONLY is nonzero, '-' as well as '--' can introduce long-named options. If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT environment variable were set. */ int _getopt_internal_r (int argc, char **argv, const char *optstring, const struct option *longopts, int *longind, int long_only, int posixly_correct, struct _getopt_data *d) { int print_errors = d->opterr; if (optstring[0] == ':') print_errors = 0; if (argc < 1) return -1; d->optarg = NULL; if (d->optind == 0 || !d->__initialized) { if (d->optind == 0) d->optind = 1; /* Don't scan ARGV[0], the program name. */ optstring = _getopt_initialize (argc, argv, optstring, posixly_correct, d); d->__initialized = 1; } /* Test whether ARGV[optind] points to a non-option argument.

Preface 1. Package naming 2. Package description 3. License 4. configure options 5. Additional documentation 6. Extra files 7. Installing XZ Utils and LZMA Utils in parallel 8. Example 0. Preface ---------- This document is meant for people who create and maintain XZ Utils packages for operating system distributions. The focus is on GNU/Linux systems, but most things apply to other systems too. While the standard "configure && make DESTDIR=$PKG install" should give a pretty good package, there are some details which packagers may want to tweak. Packagers should also read the INSTALL file. 1. Package naming ----------------- The preferred name for the XZ Utils package is "xz", because that's the name of the upstream tarball. Naturally you may have good reasons to use some other name; I won't get angry about it. ;-) It's just nice to be able to point people to the correct package name without asking what distro they have. If your distro policy is to split things into small pieces, here is one suggestion: xz xz, xzdec, scripts (xzdiff, xzgrep, etc.), docs xz-lzma lzma, unlzma, lzcat, lzgrep etc. symlinks and lzmadec binary for compatibility with LZMA Utils liblzma liblzma.so.* liblzma-devel liblzma.so, liblzma.a, API headers 2. Package description ---------------------- Here is a suggestion which you may use as the package description. If you can use only one-line description, pick only the first line. Naturally, feel free to use some other description if you find it better, and maybe send it to me too. Library and command line tools for XZ and LZMA compressed files XZ Utils provide a general purpose data compression library and command line tools. The native file format is the .xz format, but also the legacy .lzma format is supported. The .xz format supports multiple compression algorithms, of which LZMA2 is currently the primary algorithm. With typical files, XZ Utils create about 30 % smaller files than gzip. If you are splitting XZ Utils into multiple packages, here are some suggestions for package descriptions: xz: Command line tools for XZ and LZMA compressed files This package includes the xz compression tool and other command line tools from XZ Utils. xz has command line syntax similar to that of gzip. The native file format is the .xz format, but also the legacy .lzma format is supported. The .xz format supports multiple compression algorithms, of which LZMA2 is currently the primary algorithm. With typical files, XZ Utils create about 30 % smaller files than gzip. Note that this package doesn't include the files needed for LZMA Utils 4.32.x compatibility. Install also the xz-lzma package to make XZ Utils emulate LZMA Utils 4.32.x. xz-lzma: LZMA Utils emulation with XZ Utils This package includes executables and symlinks to make XZ Utils emulate lzma, unlzma, lzcat, and other command line tools found from the legacy LZMA Utils 4.32.x package. liblzma: Library for XZ and LZMA compressed files liblzma is a general purpose data compression library with an API similar to that of zlib. liblzma supports multiple algorithms, of which LZMA2 is currently the primary algorithm. The native file format is .xz, but also the legacy .lzma format and raw streams (no headers at all) are supported. This package includes the shared library. liblzma-devel: Library for XZ and LZMA compressed files This package includes the API headers, static library, and other development files related to liblzma. 3. License ---------- If the package manager supports a license field, you probably should put GPLv2+ there (GNU GPL v2 or later). The interesting parts of XZ Utils are in the public domain, but some less important files ending up into the binary package are under GPLv2+. So it is simplest to just say GPLv2+ if you cannot specify "public domain and GPLv2+". If you split XZ Utils into multiple packages as described earlier in this file, liblzma and liblzma-dev packages will contain only public domain code (from XZ Utils at least; compiler or linker may add some third-party code, which may be copyrighted). 4. configure options -------------------- Unless you are building a package for a distribution that is meant only for embedded systems, don't use the following configure options: --enable-debug --enable-encoders (*) --enable-decoders --enable-match-finders --enable-checks --enable-small (*) --disable-threads (*) (*) These are OK when building xzdec and lzmadec as described in INSTALL. xzdec and lzmadec don't provide any functionality that isn't already available in the xz tool. Shipping xzdec and lzmadec without size optimization and statically-linked liblzma isn't very useful. Doing that would give users the xzdec man page, which may make it easier for people to find out that such tools exists, but the executables wouldn't have any advantage over the full-featured xz. 5. Additional documentation --------------------------- "make install" copies some additional documentation to $docdir (--docdir in configure). There is a copy of the GNU GPL v2, which can be replaced with a symlink if your distro ships with shared copies of the common license texts. liblzma API is currently only documented using Doxygen tags in the API headers. It hasn't been tested much how good results Doxygen is able to make from the tags (e.g. Doxyfile might need tweaking, the tagging may need to be improved etc.), so it might be simpler to just let people read docs directly from the .h files for now, and also save quite a bit in package size at the same time. 6. Extra files -------------- The "extra" directory contains some small extra tools or other files. The exact set of extra files can vary between XZ Utils releases. The extra files have only limited use or they are too dangerous to be put directly to $bindir (7z2lzma.sh is a good example, since it can silently create corrupt output if certain conditions are not met). If you feel like it, you may copy the extra directory under the doc directory (e.g. /usr/share/doc/xz/extra). Maybe some people will find them useful. However, most people needing these tools probably are able to find them from the source package too. The "debug" directory contains some tools that are useful only when hacking on XZ Utils. Don't package these tools. 7. Installing XZ Utils and LZMA Utils in parallel ------------------------------------------------- XZ Utils and LZMA Utils 4.32.x can be installed in parallel by omitting the compatibility symlinks (lzma, unlzma, lzcat, lzgrep etc.) from the XZ Utils package. It's probably a good idea to still package the symlinks into a separate package so that users may choose if they want to use XZ Utils or LZMA Utils for handling .lzma files. 8. Example ---------- Here is an example for i686 GNU/Linux that - links xz and lzmainfo against shared liblzma; - links size-optimized xzdec and lzmadec against static liblzma while avoiding libpthread dependency; - includes only shared liblzma in the final package; and - copies also the "extra" directory to the package.

This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. xz-5.1.3alpha/COPYING.LGPLv2.10000644000000000000000000006364212232714400012263 00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! xz-5.1.3alpha/COPYING.GPLv30000644000000000000000000010451312232714400012002 00000000000000 GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.

The final binary package will be standalone in sense that it will depend only on DLLs that are included in all Windows installations. These instructions don't apply to Cygwin. XZ Utils can be built under Cygwin in the same way as many other packages. These instructions don't apply to MinGW and MSYS developers either, who may want to package XZ Utils for MinGW or MSYS distributions. You know who you are, and will probably use quite different configure options etc. than what is described here. Installing the toolchain(s) --------------------------- Some of the following is needed: - MSYS is always needed to use the GNU Autotools based build system. - MinGW builds 32-bit x86 binaries. - MingW-w32 builds 32-bit x86 executables too. - MinGW-w64 builds 64-bit x86-64 binaries. So you need to pick between MinGW and MinGW-w32 when building 32-bit version. You don't need both. You might find 7-Zip handy when extracting some files (especially the .tar.lzma files). The ready-made build script will also use 7-Zip to create the distributable .zip and .7z files. I used the following directory structure but you can use whatever you want. Just note that I will use these in my examples. Each of these should have a subdirectory "bin": C:\devel\tools\msys C:\devel\tools\mingw C:\devel\tools\mingw-w32 C:\devel\tools\mingw-w64 Installing MSYS You can download MSYS from MinGW's Sourceforge page: http://sourceforge.net/projects/mingw/files/ It's under "MSYS Base System". I recommend using MSYS 1.0.11 (MSYS-1.0.11.exe or msysCORE-1.0.11-bin.tar.gz) because that package includes all the required tools. At least some of the later versions include only a subset and thus you would need to download the rest separately. The old version will work fine for building XZ Utils. You can use either the .exe or .tar.gz package. I prefer .tar.gz, because it can be extracted into any directory and later removed without worrying about uninstallers. Installing MinGW You can download the required packages from MinGW's Sourceforge page: http://sourceforge.net/projects/mingw/files/ These version numbers were the latest when I wrote this document, but you probably should pick the latest versions: MinGW Runtime -> mingwrt-3.17-mingw32-dev.tar.gz MinGW API for MS-Windows -> w32api-3.14-mingw32-dev.tar.gz GNU Binutils -> binutils-2.20-1-bin.tar.gz GCC Version 4 -> gcc-full-4.4.0-mingw32-bin-2.tar.lzma The full GCC package is quite big, but if you want a smaller download, you will need to download more than one file, so I'm using the full package in this document for simplicity. Extract the packages in the above order, possibly overwriting files from packages that were extracted earlier. Installing MinGW-w32 or MinGW-w64 You can find the latest MinGW-w32 and MinGW-w64 builds here: http://sourceforge.net/projects/mingw-w64/files/ Locate the appropriate files: Toolchains targeting Win32 -> mingw-w32-*-mingw*.zip Toolchains targeting Win64 -> mingw-w64-*-mingw*.zip I don't know what is the most recommended one. I used sezero's versions from "Personal Builds", since they seemed to have a stable GCC (judging from the GCC version number only). If you will install both MinGW-w32 and MinGW-w64, remember to extract them into different directories. Building XZ Utils ----------------- Start MSYS by going to the directory C:\devel\tools\msys and running msys.bat there (double-click or use command prompt). It will start at "home" directory, which is C:\devel\tools\msys\home\YourUserName. If you have xz-5.x.x.tar.gz in C:\devel, you should be able to build it now with the following commands: cd /c/devel tar xzf xz-5.x.x.tar.gz cd xz-5.x.x bash windows/build.bash If you used some other directory than C:\devel\tools for the build tools, edit the variables near the beginning of build.bash first. If you want to build manually, read the buildit() function in build.bash. Look especially at the latter configure invocation. Be patient. Running configure and other scripts used by the build system is (very) slow under Windows. Using a snapshot from the Git repository To use a snapshot, the build system files need to be generated with autogen.sh or "autoreconf -fi" before trying to build using the above build instructions. You can install the relevant extra packages from MinGW or use Cygwin or use e.g. a GNU/Linux system to create a source package with the required build system files. xz-5.1.3alpha/windows/README-Windows.txt0000644000000000000000000001072112232714400014672 00000000000000 XZ Utils for Windows ==================== Introduction ------------ This package includes command line tools (xz.exe and a few others) and the liblzma compression library from XZ Utils. You can find the latest version and full source code from . The parts of the XZ Utils source code, that are relevant to this binary package, are in the public domain. XZ Utils have been built for this package with MinGW-w64 and linked statically against its runtime libraries. See COPYING-Windows.txt for the copyright and license information that applies to the MinGW-w64 runtime. You must include it when redistributing these XZ Utils binaries. Package contents ---------------- All executables and libraries in this package require msvcrt.dll. It's included in all recent Windows versions. On Windows 95 it might be missing, but once you get it somewhere, XZ Utils should run even on Windows 95. There are two different versions of the executable and library files. There is one directory for each type of binaries: bin_i486 32-bit x86 (i486 and up), Windows 95 and later bin_x86-64 64-bit x86-64, Windows Vista and later Each of the above directories have the following files: *.exe Command line tools. (It's useless to double-click these; use the command prompt instead.) These have been linked statically against liblzma, so they don't require liblzma.dll. Thus, you can copy e.g. xz.exe to a directory that is in PATH without copying any other files from this package. liblzma.dll Shared version of the liblzma compression library. This file is mostly useful to developers, although some non-developers might use it to upgrade their copy of liblzma. liblzma.a Static version of the liblzma compression library. This file is useful only for developers. The rest of the directories contain architecture-independent files: doc Documentation in the plain text (TXT) format. The manuals of the command line tools are provided also in the PDF format. liblzma.def is in this directory too. include C header files for liblzma. These should be compatible with most C and C++ compilers. If you have problems, try to fix it and send your fixes upstream, or at least report a bug, thanks. Linking against liblzma ----------------------- MinGW If you use MinGW, linking against liblzma.dll or liblzma.a should be straightforward. You don't need an import library to link against liblzma.dll, and for static linking, you don't need to worry about the LZMA_API_STATIC macro. Note that the MinGW distribution includes liblzma. If you are building packages that will be part of the MinGW distribution, you probably should use the version of liblzma shipped in MinGW instead of this package. Microsoft Visual C++ To link against liblzma.dll, you need to create an import library first. You need the "lib" command from MSVC and liblzma.def from the "doc" directory of this package. Here is the command that works on 32-bit x86: lib /def:liblzma.def /out:liblzma.lib /machine:ix86 On x86-64, the /machine argument has to naturally be changed: lib /def:liblzma.def /out:liblzma.lib /machine:x64 Linking against static liblzma might work too, but usually you should use liblzma.dll if possible. (Or, if having a decompressor is enough, consider using XZ Embedded or LZMA SDK which can be compiled with MSVC.) To try linking against static liblzma, rename liblzma.a to e.g. liblzma_static.lib and tell MSVC to link against it. You also need to tell lzma.h to not use __declspec(dllimport) by defining the macro LZMA_API_STATIC. You can do it either in the C/C++ code #define LZMA_API_STATIC #include or by adding it to compiler options. Other compilers If you are using some other compiler, see its documentation how to create an import library (if it is needed). If it is simple, I might consider including the instructions here.

The resulting binaries should run at least on various DOS versions and under Windows 95/98/98SE/ME, although the Windows version of XZ Utils is recommended under Windows 95 and later. This is currently experimental and has got very little testing. Note: Makefile and config.h are updated only now and then. This means that especially if you checked out a development version, building for DOS probably won't work without updating Makefile and config.h first. Getting and Installing DJGPP You may use to help deciding what to download, but as of writing (2010-10-09) that may not be the most convenient way taking into account what components are actually required to build XZ Utils. However, using the zip-picker can still be worth doing to get nice short summary of installation instructions (they can be found from readme.1st too). For a more manual method, first select a mirror from . You need the following files: unzip32.exe (if you don't already have a LFN-capable unzipper) beta/v2/djdev204.zip v2gnu/bnu219b.zip v2gnu/gcc444b.zip v2gnu/mak3791b.zip v2misc/csdpmi7b.zip If newer versions are available, probably you should try them first. Note that djdev203.zip is too old to build XZ Utils; you need at least djdev204.zip. Also note that you want csdpmi7b.zip even if you run under Windows or DOSEMU, because the XZ Utils Makefile will embed cwsdstub.exe to the resulting binaries. See the instructions in readme.1st found from djdev204.zip. Here's a short summary, but you should still read readme.1st. C:\> mkdir DJGPP C:\> cd DJGPP C:\DJGPP> c:\download\unzip32 c:\download\djdev204.zip C:\DJGPP> c:\download\unzip32 c:\download\bnu219b.zip C:\DJGPP> c:\download\unzip32 c:\download\gcc444b.zip C:\DJGPP> c:\download\unzip32 c:\download\mak3791b.zip C:\DJGPP> c:\download\unzip32 c:\download\csdpmi7b.zip C:\DJGPP> set PATH=C:\DJGPP\BIN;%PATH% C:\DJGPP> set DJGPP=C:\DJGPP\DJGPP.ENV You may want to add the last two lines into AUTOEXEC.BAT or have, for example, DJGPP.BAT which you can run before using DJGPP. Make sure you use completely upper case path in the DJGPP environment variable. This is not required by DJGPP, but the XZ Utils Makefile is a bit stupid and expects that everything in DJGPP environment variable is uppercase. Building You need to have an environment that supports long filenames (LFN). Once you have built XZ Utils, the resulting binaries can be run without long filename support. Run "make" in this directory (the directory containing this README). You should get xz.exe (and a bunch of temporary files). Other tools are not built.

It can be disabled by setting an environment variable: set lfn=n When xz is in LFN mode, it behaves pretty much the same as it does on other operating systems. Examples: xz foo.tar -> foo.tar.xz xz -d foo.tar.xz -> foo.tar xz -F lzma foo.tar -> foo.tar.lzma xz -d foo.tar.lzma -> foo.tar When LFN support isn't available or it is disabled with LFN=n environment setting, xz works in short filename (SFN) mode. This affects filename suffix handling when compressing. When compressing to the .xz format in SFN mode: - Files without an extension get .xz just like on LFN systems. - *.tar files become *.txz (shorthand for *.tar.xz). *.txz is recognized by xz on all supported operating systems. (Try to avoid confusing this with gzipped .txt files.) - Files with 1-3 character extension have their extension modified so that the last character is a dash ("-"). If the extension is already three characters, the last character is lost. The resulting *.?- or *.??- filename is recognized in LFN mode, but it isn't recognized by xz on other operating systems. Examples: xz foo -> foo.xz | xz -d foo.xz -> foo xz foo.tar -> foo.txz | xz -d foo.txz -> foo.tar xz foo.c -> foo.c- | xz -d foo.c- -> foo.c xz read.me -> read.me- | xz -d read.me- -> read.me xz foo.txt -> foo.tx- | xz -d foo.tx- -> foo.tx ! Note that in the last example above, the third character of the filename extension is lost. When compressing to the legacy .lzma format in SFN mode: - *.tar files become *.tlz (shorthand for *.tar.lzma). *.tlz is recognized by xz on all supported operating systems. - Other files become *.lzm. The original filename extension is lost. *.lzm is recognized also in LFN mode, but it is not recognized by xz on other operating systems. Examples: xz -F lzma foo -> foo.lzm | xz -d foo.lzm -> foo xz -F lzma foo.tar -> foo.tlz | xz -d foo.tlz -> foo.tar xz -F lzma foo.c -> foo.lzm | xz -d foo.lzm -> foo ! xz -F lzma read.me -> read.lzm | xz -d read.lzm -> read ! xz -F lzma foo.txt -> foo.lzm | xz -d foo.lzm -> foo ! When compressing with a custom suffix (-S .SUF, --suffix=.SUF) to any file format: - If the suffix begins with a dot, the filename extension is replaced with the new suffix. The original extension is lost. - If the suffix doesn't begin with a dot and the filename has no extension and the filename given on the command line doesn't have a dot at the end, the custom suffix is appended just like on LFN systems. - If the suffix doesn't begin with a dot and the filename has an extension (or an extension-less filename is given with a dot at the end), the last 1-3 characters of the filename extension may get overwritten to fit the given custom suffix. Examples: xz -S x foo -> foox | xz -dS x foox -> foo xz -S x foo. -> foo.x | xz -dS x foo.x -> foo xz -S .x foo -> foo.x | xz -dS .x foo.x -> foo xz -S .x foo. -> foo.x | xz -dS .x foo.x -> foo xz -S x.y foo -> foox.y | xz -dS x.y foox.y -> foo xz -S .a foo.c -> foo.a | xz -dS .a foo.a -> foo ! xz -S a foo.c -> foo.ca | xz -dS a foo.ca -> foo.c xz -S ab foo.c -> foo.cab | xz -dS ab foo.cab -> foo.c xz -S ab read.me -> read.mab | xz -dS ab read.mab -> read.m ! xz -S ab foo.txt -> foo.tab | xz -dS ab foo.tab -> foo.t ! xz -S abc foo.txt -> foo.abc | xz -dS abc foo.abc -> foo ! When decompressing, the suffix handling in SFN mode is the same as in LFN mode. The DOS-specific filenames *.lzm, *.?-, and *.??- are recognized also in LFN mode. xz handles certain uncommon situations safely: - If the generated output filename refers to the same file as the input file, xz detects this and refuses to compress or decompress the input file even if --force is used. This can happen when giving an overlong filename in SFN mode. E.g. "xz -S x foo.texinfo" would try to write to foo.tex which on SFN system is the same file as foo.texinfo. - If the generated output filename is a special file like "con" or "prn", xz detects this and refuses to compress or decompress the input file even if --force is used. Bugs xz doesn't necessarily work in Dosbox. It should work in DOSEMU. Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file when running under Windows XP Command Prompt (something goes wrong with SIGINT handling). It works correctly under Windows 95/98/98SE/ME. xz-5.1.3alpha/dos/config.h0000644000000000000000000000670212232714400012261 00000000000000/* How many MiB of RAM to assume if the real amount cannot be determined. */ #define ASSUME_RAM 32 /* Define to 1 if crc32 integrity check is enabled. */ #define HAVE_CHECK_CRC32 1 /* Define to 1 if crc64 integrity check is enabled. */ #define HAVE_CHECK_CRC64 1 /* Define to 1 if sha256 integrity check is enabled. */ #define HAVE_CHECK_SHA256 1 /* Define to 1 if arm decoder is enabled. */ #define HAVE_DECODER_ARM 1 /* Define to 1 if armthumb decoder is enabled. */ #define HAVE_DECODER_ARMTHUMB 1 /* Define to 1 if delta decoder is enabled. */ #define HAVE_DECODER_DELTA 1 /* Define to 1 if ia64 decoder is enabled. */ #define HAVE_DECODER_IA64 1 /* Define to 1 if lzma1 decoder is enabled. */ #define HAVE_DECODER_LZMA1 1 /* Define to 1 if lzma2 decoder is enabled. */ #define HAVE_DECODER_LZMA2 1 /* Define to 1 if powerpc decoder is enabled. */ #define HAVE_DECODER_POWERPC 1 /* Define to 1 if sparc decoder is enabled. */ #define HAVE_DECODER_SPARC 1 /* Define to 1 if x86 decoder is enabled. */ #define HAVE_DECODER_X86 1 /* Define to 1 if arm encoder is enabled. */ #define HAVE_ENCODER_ARM 1 /* Define to 1 if armthumb encoder is enabled. */ #define HAVE_ENCODER_ARMTHUMB 1 /* Define to 1 if delta encoder is enabled. */ #define HAVE_ENCODER_DELTA 1 /* Define to 1 if ia64 encoder is enabled. */ #define HAVE_ENCODER_IA64 1 /* Define to 1 if lzma1 encoder is enabled. */ #define HAVE_ENCODER_LZMA1 1 /* Define to 1 if lzma2 encoder is enabled. */ #define HAVE_ENCODER_LZMA2 1 /* Define to 1 if powerpc encoder is enabled. */ #define HAVE_ENCODER_POWERPC 1 /* Define to 1 if sparc encoder is enabled. */ #define HAVE_ENCODER_SPARC 1 /* Define to 1 if x86 encoder is enabled. */ #define HAVE_ENCODER_X86 1 /* Define to 1 if you have the header file. */ #define HAVE_INTTYPES_H 1 /* Define to 1 if you have the header file. */ #define HAVE_LIMITS_H 1 /* Define to 1 to enable bt2 match finder. */ #define HAVE_MF_BT2 1 /* Define to 1 to enable bt3 match finder. */ #define HAVE_MF_BT3 1 /* Define to 1 to enable bt4 match finder. */ #define HAVE_MF_BT4 1 /* Define to 1 to enable hc3 match finder. */ #define HAVE_MF_HC3 1 /* Define to 1 to enable hc4 match finder. */ #define HAVE_MF_HC4 1 /* Define to 1 if stdbool.h conforms to C99. */ #define HAVE_STDBOOL_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STDINT_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STDLIB_H 1 /* Define to 1 if you have the header file. */ #define HAVE_STRING_H 1 /* Define to 1 if you have the header file. */ #define HAVE_SYS_TIME_H 1 /* Define to 1 if you have the `utimes' function. */ #define HAVE_UTIMES 1 /* Define to 1 or 0, depending whether the compiler supports simple visibility declarations. */ #define HAVE_VISIBILITY 0 /* Define to 1 if the system has the type `_Bool'. */ #define HAVE__BOOL 1 /* Define to 1 to disable debugging code. */ #define NDEBUG 1 /* Define to the address where bug reports for this package should be sent. */ #define PACKAGE_BUGREPORT "lasse.collin@tukaani.org" /* Define to the full name of this package. */ #define PACKAGE_NAME "XZ Utils" /* Define to the home page for this package. */ #define PACKAGE_URL "http://tukaani.org/xz/" /* The size of `size_t', as computed by sizeof. */ #define SIZEOF_SIZE_T 4 /* Define to 1 if the system supports fast unaligned access to 16-bit and 32-bit integers. */ #define TUKLIB_FAST_UNALIGNED_ACCESS 1 xz-5.1.3alpha/extra/0000755000000000000000000000000012232714400011254 500000000000000xz-5.1.3alpha/extra/7z2lzma/0000755000000000000000000000000012232714400012562 500000000000000xz-5.1.3alpha/extra/7z2lzma/7z2lzma.bash0000755000000000000000000000635712232714400014665 00000000000000#!/bin/bash # ############################################################################# # # 7z2lzma.bash is very primitive .7z to .lzma converter.

MINIX 3.2.0 and later use a different libc and aren't affected by the above bug. XZ Utils doesn't have code to detect the amount of physical RAM and number of CPU cores on MINIX 3. See section 4.4 in this file about symbol visibility warnings (you may want to pass gl_cv_cc_visibility=no to configure). 1.2.4. OpenVMS XZ Utils can be built for OpenVMS, but the build system files are not included in the XZ Utils source package. The required OpenVMS-specific files are maintained by Jouk Jansen and can be downloaded here: http://nchrem.tnw.tudelft.nl/openvms/software2.html#xzutils 1.2.5. Solaris, OpenSolaris, and derivatives The following linker error has been reported on some x86 systems: ld: fatal: relocation error: R_386_GOTOFF: ... This can be worked around by passing gl_cv_cc_visibility=no as an argument to the configure script. 1.2.6. Tru64 If you try to use the native C compiler on Tru64 (passing CC=cc to configure), you may need the workaround mention in section 4.1 in this file (pass also ac_cv_prog_cc_c99= to configure). 1.2.7. Windows Building XZ Utils on Windows is supported under MinGW + MSYS, MinGW-w64 + MSYS, and Cygwin. There is windows/build.bash to ease packaging XZ Utils with MinGW(-w64) + MSYS into a redistributable .zip or .7z file. See windows/INSTALL-Windows.txt for more information. It might be possible to build liblzma with a non-GNU toolchain too, but that will probably require writing a separate makefile. Building the command line tools with non-GNU toolchains will be harder than building only liblzma. Even if liblzma is built with MinGW, the resulting DLL or static library can be used by other compilers and linkers, including MSVC. Thus, it shouldn't be a problem to use MinGW to build liblzma even if you cannot use MinGW to build the rest of your project. See windows/README-Windows.txt for details. 1.2.8. DOS There is an experimental Makefile in the "dos" directory to build XZ Utils on DOS using DJGPP. Support for long file names (LFN) is needed. See dos/README for more information. GNU Autotools based build hasn't been tried on DOS. If you try, I would like to hear if it worked. 1.3. Adding support for new platforms If you have written patches to make XZ Utils to work on previously unsupported platform, please send the patches to me! I will consider including them to the official version. It's nice to minimize the need of third-party patching. One exception: Don't request or send patches to change the whole source package to C89. I find C99 substantially nicer to write and maintain. However, the public library headers must be in C89 to avoid frustrating those who maintain programs, which are strictly in C89 or C++. 2. configure options -------------------- In most cases, the defaults are what you want. Many of the options below are useful only when building a size-optimized version of liblzma or command line tools. --enable-encoders=LIST --disable-encoders Specify a comma-separated LIST of filter encoders to build. See "./configure --help" for exact list of available filter encoders. The default is to build all supported encoders. If LIST is empty or --disable-encoders is used, no filter encoders will be built and also the code shared between encoders will be omitted. Disabling encoders will remove some symbols from the liblzma ABI, so this option should be used only when it is known to not cause problems. --enable-decoders=LIST --disable-decoders This is like --enable-encoders but for decoders. The default is to build all supported decoders. --enable-match-finders=LIST liblzma includes two categories of match finders: hash chains and binary trees. Hash chains (hc3 and hc4) are quite fast but they don't provide the best compression ratio. Binary trees (bt2, bt3 and bt4) give excellent compression ratio, but they are slower and need more memory than hash chains. You need to enable at least one match finder to build the LZMA1 or LZMA2 filter encoders. Usually hash chains are used only in the fast mode, while binary trees are used to when the best compression ratio is wanted. The default is to build all the match finders if LZMA1 or LZMA2 filter encoders are being built. --enable-checks=LIST liblzma support multiple integrity checks. CRC32 is mandatory, and cannot be omitted. See "./configure --help" for exact list of available integrity check types. liblzma and the command line tools can decompress files which use unsupported integrity check type, but naturally the file integrity cannot be verified in that case. Disabling integrity checks may remove some symbols from the liblzma ABI, so this option should be used only when it is known to not cause problems. --disable-xz --disable-xzdec --disable-lzmadec --disable-lzmainfo Don't build and install the command line tool mentioned in the option name. NOTE: Disabling xz will skip some tests in "make check". NOTE: If xzdec is disabled and lzmadec is left enabled, a dangling man page symlink lzmadec.1 -> xzdec.1 is created. --disable-lzma-links Don't create symlinks for LZMA Utils compatibility. This includes lzma, unlzma, and lzcat. If scripts are installed, also lzdiff, lzcmp, lzgrep, lzegrep, lzfgrep, lzmore, and lzless will be omitted if this option is used. --disable-scripts Don't install the scripts xzdiff, xzgrep, xzmore, xzless, and their symlinks. --disable-assembler liblzma includes some assembler optimizations. Currently there is only assembler code for CRC32 and CRC64 for 32-bit x86. All the assembler code in liblzma is position-independent code, which is suitable for use in shared libraries and position-independent executables. So far only i386 instructions are used, but the code is optimized for i686 class CPUs. If you are compiling liblzma exclusively for pre-i686 systems, you may want to disable the assembler code. --enable-unaligned-access Allow liblzma to use unaligned memory access for 16-bit and 32-bit loads and stores. This should be enabled only when the hardware supports this, i.e. when unaligned access is fast. Some operating system kernels emulate unaligned access, which is extremely slow. This option shouldn't be used on systems that rely on such emulation. Unaligned access is enabled by default on x86, x86-64, and big endian PowerPC. --enable-small Reduce the size of liblzma by selecting smaller but semantically equivalent version of some functions, and omit precomputed lookup tables. This option tends to make liblzma slightly slower. Note that while omitting the precomputed tables makes liblzma smaller on disk, the tables are still needed at run time, and need to be computed at startup. This also means that the RAM holding the tables won't be shared between applications linked against shared liblzma. This option doesn't modify CFLAGS to tell the compiler to optimize for size. You need to add -Os or equivalent flag(s) to CFLAGS manually. --enable-assume-ram=SIZE On the most common operating systems, XZ Utils is able to detect the amount of physical memory on the system. This information is used by the options --memlimit-compress, --memlimit-decompress, and --memlimit when setting the limit to a percentage of total RAM. On some systems, there is no code to detect the amount of RAM though. Using --enable-assume-ram one can set how much memory to assume on these systems. SIZE is given as MiB. The default is 128 MiB. Feel free to send patches to add support for detecting the amount of RAM on the operating system you use. See src/common/tuklib_physmem.c for details. --enable-threads=METHOD Threading support is enabled by default so normally there is no need to specify this option. Supported values for METHOD: yes Autodetect the threading method. If none is found, configure will give an error. posix Use POSIX pthreads. This is the default except on Windows outside Cygwin. win95 Use Windows 95 compatible threads. This is compatible with Windows XP and later too. This is the default for 32-bit x86 Windows builds. The `win95' threading is incompatible with --enable-small. vista Use Windows Vista compatible threads. The resulting binaries won't run on Windows XP or older. This is the default for Windows excluding 32-bit x86 builds (that is, on x86-64 the default is `vista'). no Disable threading support. This is the same as using --disable-threads. NOTE: If combined with --enable-small, the resulting liblzma won't be thread safe, that is, if a multi-threaded application calls any liblzma functions from more than one thread, something bad may happen. --enable-symbol-versions Use symbol versioning for liblzma. This is enabled by default on GNU/Linux, other GNU-based systems, and FreeBSD. --enable-debug This enables the assert() macro and possibly some other run-time consistency checks. It makes the code slower, so you normally don't want to have this enabled. --enable-werror If building with GCC, make all compiler warnings an error, that abort the compilation. This may help catching bugs, and should work on most systems. This has no effect on the resulting binaries. 2.1. Static vs. dynamic linking of liblzma On 32-bit x86, linking against static liblzma can give a minor speed improvement. Static libraries on x86 are usually compiled as position-dependent code (non-PIC) and shared libraries are built as position-independent code (PIC). PIC wastes one register, which can make the code slightly slower compared to a non-PIC version. (Note that this doesn't apply to x86-64.) If you want to link xz against static liblzma, the simplest way is to pass --disable-shared to configure. If you want also shared liblzma, run configure again and run "make install" only for src/liblzma. 2.2. Optimizing xzdec and lzmadec xzdec and lzmadec are intended to be relatively small instead of optimizing for the best speed. Thus, it is a good idea to build xzdec and lzmadec separately: - To link the tools against static liblzma, pass --disable-shared to configure. - To select somewhat size-optimized variant of some things in liblzma, pass --enable-small to configure. - Tell the compiler to optimize for size instead of speed. E.g. with GCC, put -Os into CFLAGS. - xzdec and lzmadec will never use multithreading capabilities of liblzma. You can avoid dependency on libpthread by passing --disable-threads to configure. - There are and will be no translated messages for xzdec and lzmadec, so it is fine to pass also --disable-nls to configure. - Only decoder code is needed, so you can speed up the build slightly by passing --disable-encoders to configure. This shouldn't affect the final size of the executables though, because the linker is able to omit the encoder code anyway. If you have no use for xzdec or lzmadec, you can disable them with --disable-xzdec and --disable-lzmadec. 3. xzgrep and other scripts --------------------------- 3.1. Dependencies POSIX shell (sh) and bunch of other standard POSIX tools are required to run the scripts. The configure script tries to find a POSIX compliant sh, but if it fails, you can force the shell by passing gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure script. Some of the scripts require also mktemp. The original mktemp can be found from . On GNU, most will use the mktemp program from GNU coreutils instead of the original implementation. Both mktemp versions are fine for XZ Utils (and practically for everything else too). 3.2. PATH The scripts assume that the required tools (standard POSIX utilities, mktemp, and xz) are in PATH; the scripts don't set the PATH themselves. Some people like this while some think this is a bug. Those in the latter group can easily patch the scripts before running the configure script by taking advantage of a placeholder line in the scripts. For example, to make the scripts prefix /usr/bin:/bin to PATH: perl -pi -e 's|^#SET_PATH.*$|PATH=/usr/bin:/bin:\$PATH|' \ src/scripts/xz*.in 4. Troubleshooting ------------------ 4.1. "No C99 compiler was found." You need a C99 compiler to build XZ Utils. If the configure script cannot find a C99 compiler and you think you have such a compiler installed, set the compiler command by passing CC=/path/to/c99 as an argument to the configure script. If you get this error even when you think your compiler supports C99, you can override the test by passing ac_cv_prog_cc_c99= as an argument to the configure script. The test for C99 compiler is not perfect (and it is not as easy to make it perfect as it sounds), so sometimes this may be needed. You will get a compile error if your compiler doesn't support enough C99. 4.2. "No POSIX conforming shell (sh) was found." xzgrep and other scripts need a shell that (roughly) conforms to POSIX. The configure script tries to find such a shell. If it fails, you can force the shell to be used by passing gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure script. 4.3. configure works but build fails at crc32_x86.S The easy fix is to pass --disable-assembler to the configure script. The configure script determines if assembler code can be used by looking at the configure triplet; there is currently no check if the assembler code can actually actually be built. The x86 assembler code should work on x86 GNU/Linux, *BSDs, Solaris, Darwin, MinGW, Cygwin, and DJGPP. On other x86 systems, there may be problems and the assembler code may need to be disabled with the configure option. If you get this error when building for x86-64, you have specified or the configure script has misguessed your architecture. Pass the correct configure triplet using the --build=CPU-COMPANY-SYSTEM option (see INSTALL.generic). 4.4. Lots of warnings about symbol visibility On some systems where symbol visibility isn't supported, GCC may still accept the visibility options and attributes, which will make configure think that visibility is supported. This will result in many compiler warnings. You can avoid the warnings by forcing the visibility support off by passing gl_cv_cc_visibility=no as an argument to the configure script. This has no effect on the resulting binaries, but fewer warnings looks nicer and may allow using --enable-werror. xz-5.1.3alpha/ChangeLog0000644000000000000000000000036712232714400011631 00000000000000See the commit log in the git repository: git clone http://git.tukaani.org/xz.git Note that "make dist" doesn't put this tiny file into the package.

The Free Translation Project is a way to get maintainers of free software, translators, and users all together, so that free software will gradually become able to speak many languages. A few packages already provide translations for their messages. If you found this `ABOUT-NLS' file inside a distribution, you may assume that the distributed package does use GNU `gettext' internally, itself available at your nearest GNU archive site. But you do _not_ need to install GNU `gettext' prior to configuring, installing or using this package with messages translated. Installers will find here some useful hints. These notes also explain how users should proceed for getting the programs to use the available translations. They tell how people wanting to contribute and work on translations can contact the appropriate team. When reporting bugs in the `intl/' directory or bugs which may be related to internationalization, you should tell about the version of `gettext' which is used. The information can be found in the `intl/VERSION' file, in internationalized packages. 1.1 Quick configuration advice ============================== If you want to exploit the full power of internationalization, you should configure it using ./configure --with-included-gettext to force usage of internationalizing routines provided within this package, despite the existence of internationalizing capabilities in the operating system where this package is being installed. So far, only the `gettext' implementation in the GNU C library version 2 provides as many features (such as locale alias, message inheritance, automatic charset conversion or plural form handling) as the implementation here. It is also not possible to offer this additional functionality on top of a `catgets' implementation. Future versions of GNU `gettext' will very likely convey even more functionality. So it might be a good idea to change to GNU `gettext' as soon as possible. So you need _not_ provide this option if you are using GNU libc 2 or you have installed a recent copy of the GNU gettext package with the included `libintl'. 1.2 INSTALL Matters =================== Some packages are "localizable" when properly installed; the programs they contain can be made to speak your own native language. Most such packages use GNU `gettext'. Other packages have their own ways to internationalization, predating GNU `gettext'. By default, this package will be installed to allow translation of messages. It will automatically detect whether the system already provides the GNU `gettext' functions. If not, the included GNU `gettext' library will be used. This library is wholly contained within this package, usually in the `intl/' subdirectory, so prior installation of the GNU `gettext' package is _not_ required. Installers may use special options at configuration time for changing the default behaviour. The commands: ./configure --with-included-gettext ./configure --disable-nls will, respectively, bypass any pre-existing `gettext' to use the internationalizing routines provided within this package, or else, _totally_ disable translation of messages. When you already have GNU `gettext' installed on your system and run configure without an option for your new package, `configure' will probably detect the previously built and installed `libintl.a' file and will decide to use this. This might not be desirable. You should use the more recent version of the GNU `gettext' library. I.e. if the file `intl/VERSION' shows that the library which comes with this package is more recent, you should use ./configure --with-included-gettext to prevent auto-detection. The configuration process will not test for the `catgets' function and therefore it will not be used. The reason is that even an emulation of `gettext' on top of `catgets' could not provide all the extensions of the GNU `gettext' library. Internationalized packages usually have many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. Unless translations have been forbidden at `configure' time by using the `--disable-nls' switch, all available translations are installed together with the package. However, the environment variable `LINGUAS' may be set, prior to configuration, to limit the installed set. `LINGUAS' should then contain a space separated list of two-letter codes, stating which languages are allowed. 1.3 Using This Package ====================== As a user, if your language has been installed for this package, you only have to set the `LANG' environment variable to the appropriate `LL_CC' combination. If you happen to have the `LC_ALL' or some other `LC_xxx' environment variables set, you should unset them before setting `LANG', otherwise the setting of `LANG' will not have the desired effect. Here `LL' is an ISO 639 two-letter language code, and `CC' is an ISO 3166 two-letter country code. For example, let's suppose that you speak German and live in Germany. At the shell prompt, merely execute `setenv LANG de_DE' (in `csh'), `export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). This can be done from your `.login' or `.profile' file, once and for all. You might think that the country code specification is redundant. But in fact, some languages have dialects in different countries. For example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The country code serves to distinguish the dialects. The locale naming convention of `LL_CC', with `LL' denoting the language and `CC' denoting the country, is the one use on systems based on GNU libc. On other systems, some variations of this scheme are used, such as `LL' or `LL_CC.ENCODING'. You can get the list of locales supported by your system for your language by running the command `locale -a | grep '^LL''. Not all programs have translations for all languages. By default, an English message is shown in place of a nonexistent translation. If you understand other languages, you can set up a priority list of languages. This is done through a different environment variable, called `LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' for the purpose of message handling, but you still need to have `LANG' set to the primary language; this is required by other parts of the system libraries. For example, some Swedish users who would rather read translations in German than English for when Swedish is not available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. Special advice for Norwegian users: The language code for Norwegian bokma*l changed from `no' to `nb' recently (in 2003). During the transition period, while some message catalogs for this language are installed under `nb' and some older ones under `no', it's recommended for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and older translations are used. In the `LANGUAGE' environment variable, but not in the `LANG' environment variable, `LL_CC' combinations can be abbreviated as `LL' to denote the language's main dialect. For example, `de' is equivalent to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' (Portuguese as spoken in Portugal) in this context. 1.4 Translating Teams ===================== For the Free Translation Project to be a success, we need interested people who like their own language and write it well, and who are also able to synergize with other translators speaking the same language. Each translation team has its own mailing list. The up-to-date list of teams can be found at the Free Translation Project's homepage, `http://translationproject.org/', in the "Teams" area. If you'd like to volunteer to _work_ at translating messages, you should become a member of the translating team for your own language. The subscribing address is _not_ the same as the list itself, it has `-request' appended. For example, speakers of Swedish can send a message to `sv-request@li.org', having this message body: subscribe Keep in mind that team members are expected to participate _actively_ in translations, or at solving translational difficulties, rather than merely lurking around. If your team does not exist yet and you want to start one, or if you are unsure about what to do or how to get started, please write to `coordinator@translationproject.org' to reach the coordinator for all translator teams. The English team is special. It works at improving and uniformizing the terminology in use. Proven linguistic skills are praised more than programming skills, here. 1.5 Available Packages ====================== Languages are not equally supported in all packages. The following matrix shows the current state of internationalization, as of May 2010. The matrix shows, in regard of each package, for which languages PO files have been submitted to translation coordination, with a translation percentage of at least 50%.

matrix are higher than the number of visible blocks let us expect. This is because a few extra PO files are used for implementing regional variants of languages, or language dialects. For a PO file in the matrix above to be effective, the package to which it applies should also have been internationalized and distributed as such by its maintainer. There might be an observable lag between the mere existence a PO file and its wide availability in a distribution. If May 2010 seems to be old, you may fetch a more recent copy of this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date matrix with full percentage details can be found at `http://translationproject.org/extra/matrix.html'. 1.6 Using `gettext' in new packages =================================== If you are writing a freely available program and want to internationalize it you are welcome to use GNU `gettext' in your package. Of course you have to respect the GNU Library General Public License which covers the use of the GNU `gettext' library. This means in particular that even non-free programs can use `libintl' as a shared library, whereas only free software can use `libintl' as a static library or use modified versions of `libintl'. Once the sources are changed appropriately and the setup can handle the use of `gettext' the only thing missing are the translations. The Free Translation Project is also available for packages which are not developed inside the GNU project. Therefore the information given above applies also for every other Free Software Project. Contact `coordinator@translationproject.org' to make the `.pot' files available to the translation teams. xz-5.1.3alpha/TODO0000644000000000000000000000541412232714400010545 00000000000000 XZ Utils To-Do List =================== Known bugs ---------- The test suite is too incomplete. If the memory usage limit is less than about 13 MiB, xz is unable to automatically scale down the compression settings enough even though it would be possible by switching from BT2/BT3/BT4 match finder to HC3/HC4. XZ Utils compress some files significantly worse than LZMA Utils. This is due to faster compression presets used by XZ Utils, and can often be worked around by using "xz --extreme". With some files --extreme isn't enough though: it's most likely with files that compress extremely well, so going from compression ratio of 0.003 to 0.004 means big relative increase in the compressed file size. xz doesn't quote unprintable characters when it displays file names given on the command line. tuklib_exit() doesn't block signals => EINTR is possible. SIGTSTP is not handled. If xz is stopped, the estimated remaining time and calculated (de)compression speed won't make sense in the progress indicator (xz --verbose). If liblzma has created threads and fork() gets called, liblzma code will break in the child process unless it calls exec() and doesn't touch liblzma. Missing features ---------------- Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and other streams that don't have an end of payload marker. Adjust dictionary size when the input file size is known. Maybe do this only if an option is given. xz doesn't support copying extended attributes, access control lists etc. from source to target file. Multithreaded compression: - Reduce memory usage of the current method. - Implement threaded match finders. - Implement pigz-style threading in LZMA2. Multithreaded decompression Buffer-to-buffer coding could use less RAM (especially when decompressing LZMA1 or LZMA2). I/O library is not implemented (similar to gzopen() in zlib). It will be a separate library that supports uncompressed, .gz, .bz2, .lzma, and .xz files. Support changing lzma_options_lzma.mode with lzma_filters_update(). Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at Block and Stream boundaries. lzma_strerror() to convert lzma_ret to human readable form? This is tricky, because the same error codes are used with slightly different meanings, and this cannot be fixed anymore. Documentation ------------- Some tutorial is needed for liblzma. I have planned to write some extremely well commented example programs, which would work as a tutorial. I suppose the Doxygen tags are quite OK as a quick reference once one is familiar with the liblzma API. Document the LZMA1 and LZMA2 algorithms. xz-5.1.3alpha/THANKS0000644000000000000000000000376612232714400011000 00000000000000 Thanks ====== Some people have helped more, some less, but nevertheless everyone's help has been important. :-) In alphabetical order: - Mark Adler - H.

Other implementations of the .xz format 6. Contact information 0. Overview ----------- XZ Utils provide a general-purpose data-compression library plus command-line tools. The native file format is the .xz format, but also the legacy .lzma format is supported. The .xz format supports multiple compression algorithms, which are called "filters" in the context of XZ Utils. The primary filter is currently LZMA2. With typical files, XZ Utils create about 30 % smaller files than gzip. To ease adapting support for the .xz format into existing applications and scripts, the API of liblzma is somewhat similar to the API of the popular zlib library. For the same reason, the command-line tool xz has a command-line syntax similar to that of gzip. When aiming for the highest compression ratio, the LZMA2 encoder uses a lot of CPU time and may use, depending on the settings, even hundreds of megabytes of RAM. However, in fast modes, the LZMA2 encoder competes with bzip2 in compression speed, RAM usage, and compression ratio. LZMA2 is reasonably fast to decompress. It is a little slower than gzip, but a lot faster than bzip2. Being fast to decompress means that the .xz format is especially nice when the same file will be decompressed very many times (usually on different computers), which is the case e.g. when distributing software packages. In such situations, it's not too bad if the compression takes some time, since that needs to be done only once to benefit many people. With some file types, combining (or "chaining") LZMA2 with an additional filter can improve the compression ratio. A filter chain may contain up to four filters, although usually only one or two are used. For example, putting a BCJ (Branch/Call/Jump) filter before LZMA2 in the filter chain can improve compression ratio of executable files. Since the .xz format allows adding new filter IDs, it is possible that some day there will be a filter that is, for example, much faster to compress than LZMA2 (but probably with worse compression ratio). Similarly, it is possible that some day there is a filter that will compress better than LZMA2. XZ Utils doesn't support multithreaded compression or decompression yet. It has been planned though and taken into account when designing the .xz file format. 1. Documentation ---------------- 1.1. Overall documentation README This file INSTALL.generic Generic install instructions for those not familiar with packages using GNU Autotools INSTALL Installation instructions specific to XZ Utils PACKAGERS Information to packagers of XZ Utils COPYING XZ Utils copyright and license information COPYING.GPLv2 GNU General Public License version 2 COPYING.GPLv3 GNU General Public License version 3 COPYING.LGPLv2.1 GNU Lesser General Public License version 2.1 AUTHORS The main authors of XZ Utils THANKS Incomplete list of people who have helped making this software NEWS User-visible changes between XZ Utils releases ChangeLog Detailed list of changes (commit log) TODO Known bugs and some sort of to-do list Note that only some of the above files are included in binary packages. 1.2. Documentation for command-line tools The command-line tools are documented as man pages. In source code releases (and possibly also in some binary packages), the man pages are also provided in plain text (ASCII only) and PDF formats in the directory "doc/man" to make the man pages more accessible to those whose operating system doesn't provide an easy way to view man pages. 1.3. Documentation for liblzma The liblzma API headers include short docs about each function and data type as Doxygen tags. These docs should be quite OK as a quick reference. I have planned to write a bunch of very well documented example programs, which (due to comments) should work as a tutorial to various features of liblzma. No such example programs have been written yet. For now, if you have never used liblzma, libbzip2, or zlib, I recommend learning the *basics* of the zlib API. Once you know that, it should be easier to learn liblzma. http://zlib.net/manual.html http://zlib.net/zlib_how.html 2. Version numbering -------------------- The version number format of XZ Utils is X.Y.ZS: - X is the major version. When this is incremented, the library API and ABI break. - Y is the minor version. It is incremented when new features are added without breaking the existing API or ABI. An even Y indicates a stable release and an odd Y indicates unstable (alpha or beta version). - Z is the revision. This has a different meaning for stable and unstable releases: * Stable: Z is incremented when bugs get fixed without adding any new features. This is intended to be convenient for downstream distributors that want bug fixes but don't want any new features to minimize the risk of introducing new bugs. * Unstable: Z is just a counter. API or ABI of features added in earlier unstable releases having the same X.Y may break. - S indicates stability of the release. It is missing from the stable releases, where Y is an even number. When Y is odd, S is either "alpha" or "beta" to make it very clear that such versions are not stable releases. The same X.Y.Z combination is not used for more than one stability level, i.e. after X.Y.Zalpha, the next version can be X.Y.(Z+1)beta but not X.Y.Zbeta. 3. Reporting bugs ----------------- Naturally it is easiest for me if you already know what causes the unexpected behavior. Even better if you have a patch to propose. However, quite often the reason for unexpected behavior is unknown, so here are a few things to do before sending a bug report: 1. Try to create a small example how to reproduce the issue. 2. Compile XZ Utils with debugging code using configure switches --enable-debug and, if possible, --disable-shared. If you are using GCC, use CFLAGS='-O0 -ggdb3'. Don't strip the resulting binaries. 3. Turn on core dumps. The exact command depends on your shell; for example in GNU bash it is done with "ulimit -c unlimited", and in tcsh with "limit coredumpsize unlimited". 4. Try to reproduce the suspected bug. If you get "assertion failed" message, be sure to include the complete message in your bug report. If the application leaves a coredump, get a backtrace using gdb: $ gdb /path/to/app-binary # Load the app to the debugger. (gdb) core core # Open the coredump. (gdb) bt # Print the backtrace. Copy & paste to bug report. (gdb) quit # Quit gdb. Report your bug via email or IRC (see Contact information below). Don't send core dump files or any executables. If you have a small example file(s) (total size less than 256 KiB), please include it/them as an attachment. If you have bigger test files, put them online somewhere and include a URL to the file(s) in the bug report. Always include the exact version number of XZ Utils in the bug report. If you are using a snapshot from the git repository, use "git describe" to get the exact snapshot version. If you are using XZ Utils shipped in an operating system distribution, mention the distribution name, distribution version, and exact xz package version; if you cannot repeat the bug with the code compiled from unpatched source code, you probably need to report a bug to your distribution's bug tracking system. 4. Translating the xz tool -------------------------- The messages from the xz tool have been translated into a few languages. Before starting to translate into a new language, ask the author whether someone else hasn't already started working on it. Test your translation. Testing includes comparing the translated output to the original English version by running the same commands in both your target locale and with LC_ALL=C. Ask someone to proof-read and test the translation. Testing can be done e.g. by installing xz into a temporary directory: ./configure --disable-shared --prefix=/tmp/xz-test # make -C po update-po make install bash debug/translation.bash | less bash debug/translation.bash | less -S # For --list outputs Repeat the above as needed (no need to re-run configure though). Note especially the following: - The output of --help and --long-help must look nice on an 80-column terminal. It's OK to add extra lines if needed. - In contrast, don't add extra lines to error messages and such. They are often preceded with e.g. a filename on the same line, so you have no way to predict where to put a \n. Let the terminal do the wrapping even if it looks ugly. Adding new lines will be even uglier in the generic case even if it looks nice in a few limited examples. - Be careful with column alignment in tables and table-like output (--list, --list --verbose --verbose, --info-memory, --help, and --long-help): * All descriptions of options in --help should start in the same column (but it doesn't need to be the same column as in the English messages; just be consistent if you change it). Check that both --help and --long-help look OK, since they share several strings. * --list --verbose and --info-memory print lines that have the format "Description: %s". If you need a longer description, you can put extra space between the colon and %s. Then you may need to add extra space to other strings too so that the result as a whole looks good (all values start at the same column). * The columns of the actual tables in --list --verbose --verbose should be aligned properly. Abbreviate if necessary. It might be good to keep at least 2 or 3 spaces between column headings and avoid spaces in the headings so that the columns stand out better, but this is a matter of opinion. Do what you think looks best. - Be careful to put a period at the end of a sentence when the original version has it, and don't put it when the original doesn't have it. Similarly, be careful with \n characters at the beginning and end of the strings. - Read the TRANSLATORS comments that have been extracted from the source code and included in xz.pot. If they suggest testing the translation with some type of command, do it. If testing needs input files, use e.g. tests/files/good-*.xz. - When updating the translation, read the fuzzy (modified) strings carefully, and don't mark them as updated before you actually have updated them. Reading through the unchanged messages can be good too; sometimes you may find a better wording for them. - If you find language problems in the original English strings, feel free to suggest improvements. Ask if something is unclear. - The translated messages should be understandable (sometimes this may be a problem with the original English messages too). Don't make a direct word-by-word translation from English especially if the result doesn't sound good in your language. In short, take your time and pay attention to the details. Making a good translation is not a quick and trivial thing to do. The translated xz should look as polished as the English version. 5. Other implementations of the .xz format ------------------------------------------ 7-Zip and the p7zip port of 7-Zip support the .xz format starting from the version 9.00alpha. http://7-zip.org/ http://p7zip.sourceforge.net/ XZ Embedded is a limited implementation written for use in the Linux kernel, but it is also suitable for other embedded use. http://tukaani.org/xz/embedded.html 6. Contact information ---------------------- If you have questions, bug reports, patches etc. related to XZ Utils, contact Lasse Collin (in Finnish or English). I'm sometimes slow at replying. If you haven't got a reply within two weeks, assume that your email has got lost and resend it or use IRC. You can find me also from #tukaani on Freenode; my nick is Larhzu. The channel tends to be pretty quiet, so just ask your question and someone may wake up. xz-5.1.3alpha/NEWS0000644000000000000000000003151412232714400010554 00000000000000 XZ Utils Release Notes ====================== 5.1.3alpha (2013-10-26) * All fixes from 5.0.5 * liblzma: - Fixed a deadlock in the threaded encoder. - Made the uses of lzma_allocator const correct. - Added lzma_block_uncomp_encode() to create uncompressed .xz Blocks using LZMA2 uncompressed chunks. - Added support for native threads on Windows and the ability to detect the number of CPU cores. * xz: - Fixed a race condition in the signal handling. It was possible that e.g. the first SIGINT didn't make xz exit if reading or writing blocked and one had bad luck. The fix is non-trivial, so as of writing it is unknown if it will be backported to the v5.0 branch. - Made the progress indicator work correctly in threaded mode. - Threaded encoder now works together with --block-list=SIZES. - Added preliminary support for --flush-timeout=TIMEOUT. It can be useful for (somewhat) real-time streaming. For now the decompression side has to be done with something else than the xz tool due to how xz does buffering, but this should be fixed. 5.1.2alpha (2012-07-04) * All fixes from 5.0.3 and 5.0.4 * liblzma: - Fixed a deadlock and an invalid free() in the threaded encoder. - Added support for symbol versioning. It is enabled by default on GNU/Linux, other GNU-based systems, and FreeBSD. - Use SHA-256 implementation from the operating system if one is available in libc, libmd, or libutil. liblzma won't use e.g. OpenSSL or libgcrypt to avoid introducing new dependencies. - Fixed liblzma.pc for static linking. - Fixed a few portability bugs. * xz --decompress --single-stream now fixes the input position after successful decompression. Now the following works: echo foo | xz > foo.xz echo bar | xz >> foo.xz ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz Note that it doesn't work if the input is not seekable or if there is Stream Padding between the concatenated .xz Streams. * xz -lvv now shows the minimum xz version that is required to decompress the file. Currently it is 5.0.0 for all supported .xz files except files with empty LZMA2 streams require 5.0.2. * Added an *incomplete* implementation of --block-list=SIZES to xz. It only works correctly in single-threaded mode and when --block-size isn't used at the same time. --block-list allows specifying the sizes of Blocks which can be useful e.g. when creating files for random-access reading. 5.1.1alpha (2011-04-12) * All fixes from 5.0.2 * liblzma fixes that will also be included in 5.0.3: - A memory leak was fixed. - lzma_stream_buffer_encode() no longer creates an empty .xz Block if encoding an empty buffer. Such an empty Block with LZMA2 data would trigger a bug in 5.0.1 and older (see the first bullet point in 5.0.2 notes). When releasing 5.0.2, I thought that no encoder creates this kind of files but I was wrong. - Validate function arguments better in a few functions. Most importantly, specifying an unsupported integrity check to lzma_stream_buffer_encode() no longer creates a corrupt .xz file. Probably no application tries to do that, so this shouldn't be a big problem in practice. - Document that lzma_block_buffer_encode(), lzma_easy_buffer_encode(), lzma_stream_encoder(), and lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. - The return values of the _memusage() functions are now documented better. * Support for multithreaded compression was added using the simplest method, which splits the input data into blocks and compresses them independently. Other methods will be added in the future. The current method has room for improvement, e.g. it is possible to reduce the memory usage. * Added the options --single-stream and --block-size=SIZE to xz. * xzdiff and xzgrep now support .lzo files if lzop is installed. The .tzo suffix is also recognized as a shorthand for .tar.lzo. * Support for short 8.3 filenames under DOS was added to xz. It is experimental and may change before it gets into a stable release. 5.0.5 (2013-06-30) * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing .lzma files that have less common settings in the headers (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed size greater than 256 GiB). The limitations existed to avoid false positives when detecting .lzma files. The lc + lp <= 4 limitation still remains since liblzma's LZMA decoder has that limitation. NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT affected by this change. They still consider uncommon .lzma headers as not being in the .lzma format. Changing this would give way too many false positives. * xz: - Interaction of preset and custom filter chain options was made less illogical. This affects only certain less typical uses cases so few people are expected to notice this change. Now when a custom filter chain option (e.g. --lzma2) is specified, all preset options (-0 ... -9, -e) earlier are on the command line are completely forgotten. Similarly, when a preset option is specified, all custom filter chain options earlier on the command line are completely forgotten. Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e" which is equivalent to "xz -6e". Earlier -e didn't put xz back into preset mode and thus the example command was equivalent to "xz --lzma2=preset=5". Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to "xz -7". Earlier a custom filter chain option didn't make xz forget the -e option so the example was equivalent to "xz -7e". - Fixes and improvements to error handling. - Various fixes to the man page. * xzless: Fixed to work with "less" versions 448 and later. * xzgrep: Made -h an alias for --no-filename. * Include the previously missing debug/translation.bash which can be useful for translators. * Include a build script for Mac OS X. This has been in the Git repository since 2010 but due to a mistake in Makefile.am the script hasn't been included in a release tarball before. 5.0.4 (2012-06-22) * liblzma: - Fix lzma_index_init(). It could crash if memory allocation failed. - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ filter is used and the application only provides exactly as much output space as is the uncompressed size of the file. - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't check if the last call to lzma_code() really returned LZMA_STREAM_END, which made the program think that truncated files are valid. - New example programs in doc/examples (old programs are now in doc/examples_old). These have more comments and more detailed error handling. * Fix "xz -lvv foo.xz". It could crash on some corrupted files. * Fix output of "xz --robot -lv" and "xz --robot -lvv" which incorrectly printed the filename also in the "foo (x/x)" format. * Fix exit status of "xzdiff foo.xz bar.xz". * Fix exit status of "xzgrep foo binary_file". * Fix portability to EBCDIC systems. * Fix a configure issue on AIX with the XL C compiler. See INSTALL for details. * Update French, German, Italian, and Polish translations. 5.0.3 (2011-05-21) * liblzma fixes: - A memory leak was fixed. - lzma_stream_buffer_encode() no longer creates an empty .xz Block if encoding an empty buffer. Such an empty Block with LZMA2 data would trigger a bug in 5.0.1 and older (see the first bullet point in 5.0.2 notes). When releasing 5.0.2, I thought that no encoder creates this kind of files but I was wrong. - Validate function arguments better in a few functions. Most importantly, specifying an unsupported integrity check to lzma_stream_buffer_encode() no longer creates a corrupt .xz file. Probably no application tries to do that, so this shouldn't be a big problem in practice. - Document that lzma_block_buffer_encode(), lzma_easy_buffer_encode(), lzma_stream_encoder(), and lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. - The return values of the _memusage() functions are now documented better. * Fix command name detection in xzgrep. xzegrep and xzfgrep now correctly use egrep and fgrep instead of grep. * French translation was added. 5.0.2 (2011-04-01) * LZMA2 decompressor now correctly accepts LZMA2 streams with no uncompressed data. Previously it considered them corrupt. The bug can affect applications that use raw LZMA2 streams. It is very unlikely to affect .xz files because no compressor creates .xz files with empty LZMA2 streams. (Empty .xz files are a different thing than empty LZMA2 streams.) * "xz --suffix=.foo filename.foo" now refuses to compress the file due to it already having the suffix .foo. It was already documented on the man page, but the code lacked the test. * "xzgrep -l foo bar.xz" works now. * Polish translation was added. 5.0.1 (2011-01-29) * xz --force now (de)compresses files that have setuid, setgid, or sticky bit set and files that have multiple hard links. The man page had it documented this way already, but the code had a bug. * gzip and bzip2 support in xzdiff was fixed. * Portability fixes * Minor fix to Czech translation 5.0.0 (2010-10-23) Only the most important changes compared to 4.999.9beta are listed here. One change is especially important: * The memory usage limit is now disabled by default. Some scripts written before this change may have used --memory=max on xz command line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED NOW, because they interfere with user's ability to set the memory usage limit himself. If user-specified limit causes problems to your script, blame the user. Other significant changes: * Added support for XZ_DEFAULTS environment variable. This variable allows users to set default options for xz, e.g. default memory usage limit or default compression level. Scripts that use xz must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT instead if they need a way to pass options to xz via an environment variable. * The compression settings associated with the preset levels -0 ... -9 have been changed. --extreme was changed a little too. It is now less likely to make compression worse, but with some files the new --extreme may compress slightly worse than the old --extreme. * If a preset level (-0 ... -9) is specified after a custom filter chain options have been used (e.g. --lzma2), the custom filter chain will be forgotten. Earlier the preset options were completely ignored after custom filter chain options had been seen. * xz will create sparse files when decompressing if the uncompressed data contains long sequences of binary zeros. This is done even when writing to standard output that is connected to a regular file and certain additional conditions are met to make it safe. * Support for "xz --list" was added. Combine with --verbose or --verbose --verbose (-vv) for detailed output. * I had hoped that liblzma API would have been stable after 4.999.9beta, but there have been a couple of changes in the advanced features, which don't affect most applications: - Index handling code was revised. If you were using the old API, you will get a compiler error (so it's easy to notice). - A subtle but important change was made to the Block handling API. lzma_block.version has to be initialized even for lzma_block_header_decode(). Code that doesn't do it will work for now, but might break in the future, which makes this API change easy to miss. * The major soname has been bumped to 5.0.0. liblzma API and ABI are now stable, so the need to recompile programs linking against liblzma shouldn't arise soon. xz-5.1.3alpha/COPYING.GPLv20000644000000000000000000004325412232714400012005 00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

Here is a rough summary of which licenses apply to which parts of this package (but check the individual files to be sure!): - liblzma is in the public domain. - xz, xzdec, and lzmadec command line tools are in the public domain unless GNU getopt_long had to be compiled and linked in from the lib directory. The getopt_long code is under GNU LGPLv2.1+. - The scripts to grep, diff, and view compressed files have been adapted from gzip. These scripts and their documentation are under GNU GPLv2+. - All the documentation in the doc directory and most of the XZ Utils specific documentation files in other directories are in the public domain. - Translated messages are in the public domain. - The build system contains public domain files, and files that are under GNU GPLv2+ or GNU GPLv3+. None of these files end up in the binaries being built. - Test files and test code in the tests directory, and debugging utilities in the debug directory are in the public domain. - The extra directory may contain public domain files, and files that are under various free software licenses. You can do whatever you want with the files that have been put into the public domain. If you find public domain legally problematic, take the previous sentence as a license grant. If you still find the lack of copyright legally problematic, you have too many lawyers. As usual, this software is provided "as is", without any warranty. If you copy significant amounts of public domain code from XZ Utils into your project, acknowledging this somewhere in your software is polite (especially if it is proprietary, non-free software), but naturally it is not legally required. Here is an example of a good notice to put into "about box" or into documentation: This software includes code from XZ Utils . The following license texts are included in the following files: - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1 - COPYING.GPLv2: GNU General Public License version 2 - COPYING.GPLv3: GNU General Public License version 3 Note that the toolchain (compiler, linker etc.) may add some code pieces that are copyrighted. Thus, it is possible that e.g. liblzma binary wouldn't actually be in the public domain in its entirety even though it contains no copyrighted code from the XZ Utils source package. If you have questions, don't hesitate to ask the author(s) for more information. xz-5.1.3alpha/AUTHORS0000644000000000000000000000202312232714400011116 00000000000000 Authors of XZ Utils =================== XZ Utils is developed and maintained by Lasse Collin . Major parts of liblzma are based on code written by Igor Pavlov, specifically the LZMA SDK . Without this code, XZ Utils wouldn't exist. The SHA-256 implementation in liblzma is based on the code found from 7-Zip , which has a modified version of the SHA-256 code found from Crypto++ . The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai. Some scripts have been adapted from gzip. The original versions were written by Jean-loup Gailly, Charles Levert, and Paul Eggert. Andrew Dudman helped adapting the scripts and their man pages for XZ Utils. The GNU Autotools-based build system contains files from many authors, which I'm not trying to list here. Several people have contributed fixes or reported bugs. Most of them are mentioned in the file THANKS. xz-5.1.3alpha/Doxyfile.in0000644000000000000000000014245012232714400012172 00000000000000# Doxyfile 1.4.7 # Copyright (C) 1997-2007 by Dimitri van Heesch # License: GNU GPLv2+ # This file describes the settings to be used by the documentation system # doxygen (www.doxygen.org) for a project # # All text after a hash (#) is considered a comment and will be ignored # The format is: # TAG = value [value, ...] # For lists items can also be appended using: # TAG += value [value, ...] # Values that contain spaces should be placed between quotes (" ") #--------------------------------------------------------------------------- # Project related configuration options #--------------------------------------------------------------------------- # The PROJECT_NAME tag is a single word (or a sequence of words surrounded # by quotes) that should identify the project.

Available integrity checks: crc32 crc64 sha256 --disable-assembler Do not use assembler optimizations even if such exist for the architecture. --enable-small Make liblzma smaller and a little slower. This is disabled by default to optimize for speed. --enable-threads=METHOD Supported METHODS are `yes', `no', `posix', `win95', and `vista'. The default is `yes'. Using `no' together with --enable-small makes liblzma thread unsafe. --enable-assume-ram=SIZE If and only if the real amount of RAM cannot be determined, assume SIZE MiB. The default is 128 MiB.

The dnl default (if it is not specified or empty) is 'no-libtool'. dnl INTLSYMBOL should be 'external' for packages with no intl directory, dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. dnl If INTLSYMBOL is 'use-libtool', then a libtool library dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, dnl depending on --{enable,disable}-{shared,static} and on the presence of dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library dnl $(top_builddir)/intl/libintl.a will be created. dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext dnl implementations (in libc or libintl) without the ngettext() function dnl will be ignored. If NEEDSYMBOL is specified and is dnl 'need-formatstring-macros', then GNU gettext implementations that don't dnl support the ISO C 99 formatstring macros will be ignored. dnl INTLDIR is used to find the intl libraries. If empty, dnl the value `$(top_builddir)/intl/' is used. dnl dnl The result of the configuration is one of three cases: dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled dnl and used. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 2) GNU gettext has been found in the system's C library. dnl Catalog format: GNU --> install in $(datadir) dnl Catalog extension: .mo after installation, .gmo in source tree dnl 3) No internationalization, always use English msgid. dnl Catalog format: none dnl Catalog extension: none dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. dnl The use of .gmo is historical (it was needed to avoid overwriting the dnl GNU format catalogs when building on a platform with an X/Open gettext), dnl but we keep it in order not to force irrelevant filename changes on the dnl maintainers. dnl AC_DEFUN([AM_GNU_GETTEXT], [ dnl Argument checking. ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT ])])])])]) ifelse(ifelse([$1], [], [old])[]ifelse([$1], [no-libtool], [old]), [old], [AC_DIAGNOSE([obsolete], [Use of AM_GNU_GETTEXT without [external] argument is deprecated.])]) ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT ])])])]) define([gt_included_intl], ifelse([$1], [external], ifdef([AM_GNU_GETTEXT_][INTL_SUBDIR], [yes], [no]), [yes])) define([gt_libtool_suffix_prefix], ifelse([$1], [use-libtool], [l], [])) gt_NEEDS_INIT AM_GNU_GETTEXT_NEED([$2]) AC_REQUIRE([AM_PO_SUBDIRS])dnl ifelse(gt_included_intl, yes, [ AC_REQUIRE([AM_INTL_SUBDIR])dnl ]) dnl Prerequisites of AC_LIB_LINKFLAGS_BODY.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

To use a pager other than the default more, set environment variable PAGER to the name of the desired program. The name lzmore is provided for backward compatibility with LZMA Utils. e or q When the prompt --More--(Next file: file) is printed, this com- mand causes xzmore to exit. s When the prompt --More--(Next file: file) is printed, this com- mand causes xzmore to skip the next file and continue.

It works on files compressed with xz(1) or lzma(1). If no files are given, xzless reads from standard input. xzless uses less(1) to present its output. Unlike xzmore, its choice of pager cannot be altered by setting an environment variable. Com- mands are based on both more(1) and vi(1) and allow back and forth movement and searching. See the less(1) manual for more information. The command named lzless is provided for backward compatibility with LZMA Utils. ENVIRONMENT LESSMETACHARS A list of characters special to the shell.

If no file is specified, then standard input is decompressed if neces- sary and fed to grep(1). When reading from standard input, gzip(1), bzip2(1), and lzop(1) compressed files are not supported. If xzgrep is invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1). The same applies to names lzgrep, lzegrep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

All options specified are passed directly to cmp(1) or diff(1). If only one file is speci- fied, then the files compared are file1 (which must have a suffix of a supported compression format) and file1 from which the compression for- mat suffix has been stripped. If two files are specified, then they are uncompressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1) or diff(1) is preserved.

It reads the first 13 bytes from the specified file, decodes the header, and prints it to standard output in human readable format. If no files are given or file is -, standard input is read. Usually the most interesting information is the uncompressed size and the dictionary size. Uncompressed size can be shown only if the file is in the non-streamed .lzma format variant. The amount of memory required to decompress the file is a few dozen kilobytes plus the dic- tionary size. lzmainfo is included in XZ Utils primarily for backward compatibility with LZMA Utils. EXIT STATUS 0 All is good. 1 An error occurred. BUGS lzmainfo uses MB while the correct suffix would be MiB (2^20 bytes). This is to keep the output compatible with LZMA Utils.

To reduce the size of the executable, xzdec doesn't support multi- threading or localization, and doesn't read options from XZ_DEFAULTS and XZ_OPT environment variables. xzdec doesn't support displaying intermediate progress information: sending SIGINFO to xzdec does noth- ing, but sending SIGUSR1 terminates the process instead of displaying progress information. OPTIONS -d, --decompress, --uncompress Ignored for xz(1) compatibility. xzdec supports only decompres- sion. -k, --keep Ignored for xz(1) compatibility. xzdec never creates or removes any files. -c, --stdout, --to-stdout Ignored for xz(1) compatibility. xzdec always writes the decom- pressed data to standard output. -q, --quiet Specifying this once does nothing since xzdec never displays any warnings or notices. Specify this twice to suppress errors. -Q, --no-warn Ignored for xz(1) compatibility. xzdec never uses the exit sta- tus 2. -h, --help Display a help message and exit successfully. -V, --version Display the version number of xzdec and liblzma. EXIT STATUS 0 All was good. 1 An error occurred. xzdec doesn't have any warning messages like xz(1) has, thus the exit status 2 is not used by xzdec. NOTES Use xz(1) instead of xzdec or lzmadec for normal everyday use. xzdec or lzmadec are meant only for situations where it is important to have a smaller decompressor than the full-featured xz(1). xzdec and lzmadec are not really that small. The size can be reduced further by dropping features from liblzma at compile time, but that shouldn't usually be done for executables distributed in typical non- embedded operating system distributions. If you need a truly small .xz decompressor, consider using XZ Embedded.

When writing scripts that need to decompress files, it is recommended to always use the name xz with appropriate arguments (xz -d or xz -dc) instead of the names unxz and xzcat. DESCRIPTION xz is a general-purpose data compression tool with command line syntax similar to gzip(1) and bzip2(1). The native file format is the .xz format, but the legacy .lzma format used by LZMA Utils and raw com- pressed streams with no container format headers are also supported. xz compresses or decompresses each file according to the selected oper- ation mode. If no files are given or file is -, xz reads from standard input and writes the processed data to standard output. xz will refuse (display an error and skip the file) to write compressed data to stan- dard output if it is a terminal. Similarly, xz will refuse to read compressed data from standard input if it is a terminal. Unless --stdout is specified, files other than - are written to a new file whose name is derived from the source file name: o When compressing, the suffix of the target file format (.xz or .lzma) is appended to the source filename to get the target file- name. o When decompressing, the .xz or .lzma suffix is removed from the filename to get the target filename. xz also recognizes the suf- fixes .txz and .tlz, and replaces them with the .tar suffix. If the target file already exists, an error is displayed and the file is skipped. Unless writing to standard output, xz will display a warning and skip the file if any of the following applies: o File is not a regular file. Symbolic links are not followed, and thus they are not considered to be regular files. o File has more than one hard link. o File has setuid, setgid, or sticky bit set. o The operation mode is set to compress and the file already has a suffix of the target file format (.xz or .txz when compressing to the .xz format, and .lzma or .tlz when compressing to the .lzma for- mat). o The operation mode is set to decompress and the file doesn't have a suffix of any of the supported file formats (.xz, .txz, .lzma, or .tlz). After successfully compressing or decompressing the file, xz copies the owner, group, permissions, access time, and modification time from the source file to the target file. If copying the group fails, the per- missions are modified so that the target file doesn't become accessible to users who didn't have permission to access the source file. xz doesn't support copying other metadata like access control lists or extended attributes yet. Once the target file has been successfully closed, the source file is removed unless --keep was specified. The source file is never removed if the output is written to standard output. Sending SIGINFO or SIGUSR1 to the xz process makes it print progress information to standard error. This has only limited use since when standard error is a terminal, using --verbose will display an automati- cally updating progress indicator. Memory usage The memory usage of xz varies from a few hundred kilobytes to several gigabytes depending on the compression settings. The settings used when compressing a file determine the memory requirements of the decom- pressor. Typically the decompressor needs 5 % to 20 % of the amount of memory that the compressor needed when creating the file. For example, decompressing a file created with xz -9 currently requires 65 MiB of memory. Still, it is possible to have .xz files that require several gigabytes of memory to decompress. Especially users of older systems may find the possibility of very large memory usage annoying. To prevent uncomfortable surprises, xz has a built-in memory usage limiter, which is disabled by default. While some operating systems provide ways to limit the memory usage of processes, relying on it wasn't deemed to be flexible enough (e.g. using ulimit(1) to limit virtual memory tends to cripple mmap(2)). The memory usage limiter can be enabled with the command line option --memlimit=limit. Often it is more convenient to enable the limiter by default by setting the environment variable XZ_DEFAULTS, e.g. XZ_DEFAULTS=--memlimit=150MiB. It is possible to set the limits sepa- rately for compression and decompression by using --memlimit-com- press=limit and --memlimit-decompress=limit. Using these two options outside XZ_DEFAULTS is rarely useful because a single run of xz cannot do both compression and decompression and --memlimit=limit (or -M limit) is shorter to type on the command line. If the specified memory usage limit is exceeded when decompressing, xz will display an error and decompressing the file will fail. If the limit is exceeded when compressing, xz will try to scale the settings down so that the limit is no longer exceeded (except when using --for- mat=raw or --no-adjust). This way the operation won't fail unless the limit is very small. The scaling of the settings is done in steps that don't match the compression level presets, e.g. if the limit is only slightly less than the amount required for xz -9, the settings will be scaled down only a little, not all the way down to xz -8. Concatenation and padding with .xz files It is possible to concatenate .xz files as is. xz will decompress such files as if they were a single .xz file. It is possible to insert padding between the concatenated parts or after the last part. The padding must consist of null bytes and the size of the padding must be a multiple of four bytes. This can be use- ful e.g. if the .xz file is stored on a medium that measures file sizes in 512-byte blocks. Concatenation and padding are not allowed with .lzma files or raw streams. OPTIONS Integer suffixes and special values In most places where an integer argument is expected, an optional suf- fix is supported to easily indicate large integers. There must be no space between the integer and the suffix. KiB Multiply the integer by 1,024 (2^10). Ki, k, kB, K, and KB are accepted as synonyms for KiB. MiB Multiply the integer by 1,048,576 (2^20). Mi, m, M, and MB are accepted as synonyms for MiB. GiB Multiply the integer by 1,073,741,824 (2^30). Gi, g, G, and GB are accepted as synonyms for GiB. The special value max can be used to indicate the maximum integer value supported by the option. Operation mode If multiple operation mode options are given, the last one takes effect. -z, --compress Compress. This is the default operation mode when no operation mode option is specified and no other operation mode is implied from the command name (for example, unxz implies --decompress). -d, --decompress, --uncompress Decompress. -t, --test Test the integrity of compressed files. This option is equiva- lent to --decompress --stdout except that the decompressed data is discarded instead of being written to standard output. No files are created or removed. -l, --list Print information about compressed files. No uncompressed out- put is produced, and no files are created or removed. In list mode, the program cannot read the compressed data from standard input or from other unseekable sources. The default listing shows basic information about files, one file per line. To get more detailed information, use also the --verbose option. For even more information, use --verbose twice, but note that this may be slow, because getting all the extra information requires many seeks. The width of verbose output exceeds 80 characters, so piping the output to e.g. less -S may be convenient if the terminal isn't wide enough. The exact output may vary between xz versions and different locales. For machine-readable output, --robot --list should be used. Operation modifiers -k, --keep Don't delete the input files. -f, --force This option has several effects: o If the target file already exists, delete it before compress- ing or decompressing. o Compress or decompress even if the input is a symbolic link to a regular file, has more than one hard link, or has the setuid, setgid, or sticky bit set. The setuid, setgid, and sticky bits are not copied to the target file. o When used with --decompress --stdout and xz cannot recognize the type of the source file, copy the source file as is to standard output. This allows xzcat --force to be used like cat(1) for files that have not been compressed with xz. Note that in future, xz might support new compressed file formats, which may make xz decompress more types of files instead of copying them as is to standard output. --format=format can be used to restrict xz to decompress only a single file for- mat. -c, --stdout, --to-stdout Write the compressed or decompressed data to standard output instead of a file. This implies --keep. --single-stream Decompress only the first .xz stream, and silently ignore possi- ble remaining input data following the stream. Normally such trailing garbage makes xz display an error. xz never decompresses more than one stream from .lzma files or raw streams, but this option still makes xz ignore the possible trailing data after the .lzma file or raw stream. This option has no effect if the operation mode is not --decom- press or --test. --no-sparse Disable creation of sparse files. By default, if decompressing into a regular file, xz tries to make the file sparse if the decompressed data contains long sequences of binary zeros. It also works when writing to standard output as long as standard output is connected to a regular file and certain additional conditions are met to make it safe. Creating sparse files may save disk space and speed up the decompression by reducing the amount of disk I/O. -S .suf, --suffix=.suf When compressing, use .suf as the suffix for the target file instead of .xz or .lzma. If not writing to standard output and the source file already has the suffix .suf, a warning is dis- played and the file is skipped. When decompressing, recognize files with the suffix .suf in addition to files with the .xz, .txz, .lzma, or .tlz suffix. If the source file has the suffix .suf, the suffix is removed to get the target filename. When compressing or decompressing raw streams (--format=raw), the suffix must always be specified unless writing to standard output, because there is no default suffix for raw streams. --files[=file] Read the filenames to process from file; if file is omitted, filenames are read from standard input. Filenames must be ter- minated with the newline character. A dash (-) is taken as a regular filename; it doesn't mean standard input. If filenames are given also as command line arguments, they are processed before the filenames read from file. --files0[=file] This is identical to --files[=file] except that each filename must be terminated with the null character. Basic file format and compression options -F format, --format=format Specify the file format to compress or decompress: auto This is the default. When compressing, auto is equiva- lent to xz. When decompressing, the format of the input file is automatically detected. Note that raw streams (created with --format=raw) cannot be auto-detected. xz Compress to the .xz file format, or accept only .xz files when decompressing. lzma, alone Compress to the legacy .lzma file format, or accept only .lzma files when decompressing. The alternative name alone is provided for backwards compatibility with LZMA Utils. raw Compress or uncompress a raw stream (no headers). This is meant for advanced users only. To decode raw streams, you need use --format=raw and explicitly specify the fil- ter chain, which normally would have been stored in the container headers. -C check, --check=check Specify the type of the integrity check. The check is calcu- lated from the uncompressed data and stored in the .xz file. This option has an effect only when compressing into the .xz format; the .lzma format doesn't support integrity checks. The integrity check (if any) is verified when the .xz file is decom- pressed. Supported check types: none Don't calculate an integrity check at all. This is usu- ally a bad idea. This can be useful when integrity of the data is verified by other means anyway. crc32 Calculate CRC32 using the polynomial from IEEE-802.3 (Ethernet). crc64 Calculate CRC64 using the polynomial from ECMA-182. This is the default, since it is slightly better than CRC32 at detecting damaged files and the speed difference is neg- ligible. sha256 Calculate SHA-256. This is somewhat slower than CRC32 and CRC64. Integrity of the .xz headers is always verified with CRC32. It is not possible to change or disable it. -0 ... -9 Select a compression preset level. The default is -6. If mul- tiple preset levels are specified, the last one takes effect. If a custom filter chain was already specified, setting a com- pression preset level clears the custom filter chain. The differences between the presets are more significant than with gzip(1) and bzip2(1). The selected compression settings determine the memory requirements of the decompressor, thus using a too high preset level might make it painful to decom- press the file on an old system with little RAM. Specifically, it's not a good idea to blindly use -9 for everything like it often is with gzip(1) and bzip2(1). -0 ... -3 These are somewhat fast presets. -0 is sometimes faster than gzip -9 while compressing much better. The higher ones often have speed comparable to bzip2(1) with compa- rable or better compression ratio, although the results depend a lot on the type of data being compressed. -4 ... -6 Good to very good compression while keeping decompressor memory usage reasonable even for old systems. -6 is the default, which is usually a good choice e.g. for dis- tributing files that need to be decompressible even on systems with only 16 MiB RAM. (-5e or -6e may be worth considering too. See --extreme.) -7 ... -9 These are like -6 but with higher compressor and decom- pressor memory requirements. These are useful only when compressing files bigger than 8 MiB, 16 MiB, and 32 MiB, respectively. On the same hardware, the decompression speed is approximately a constant number of bytes of compressed data per second. In other words, the better the compression, the faster the decom- pression will usually be. This also means that the amount of uncompressed output produced per second can vary a lot. The following table summarises the features of the presets: Preset DictSize CompCPU CompMem DecMem -0 256 KiB 0 3 MiB 1 MiB -1 1 MiB 1 9 MiB 2 MiB -2 2 MiB 2 17 MiB 3 MiB -3 4 MiB 3 32 MiB 5 MiB -4 4 MiB 4 48 MiB 5 MiB -5 8 MiB 5 94 MiB 9 MiB -6 8 MiB 6 94 MiB 9 MiB -7 16 MiB 6 186 MiB 17 MiB -8 32 MiB 6 370 MiB 33 MiB -9 64 MiB 6 674 MiB 65 MiB Column descriptions: o DictSize is the LZMA2 dictionary size. It is waste of memory to use a dictionary bigger than the size of the uncompressed file. This is why it is good to avoid using the presets -7 ... -9 when there's no real need for them. At -6 and lower, the amount of memory wasted is usually low enough to not mat- ter. o CompCPU is a simplified representation of the LZMA2 settings that affect compression speed. The dictionary size affects speed too, so while CompCPU is the same for levels -6 ... -9, higher levels still tend to be a little slower. To get even slower and thus possibly better compression, see --extreme. o CompMem contains the compressor memory requirements in the single-threaded mode. It may vary slightly between xz ver- sions. Memory requirements of some of the future multi- threaded modes may be dramatically higher than that of the single-threaded mode. o DecMem contains the decompressor memory requirements. That is, the compression settings determine the memory require- ments of the decompressor. The exact decompressor memory usage is slightly more than the LZMA2 dictionary size, but the values in the table have been rounded up to the next full MiB. -e, --extreme Use a slower variant of the selected compression preset level (-0 ... -9) to hopefully get a little bit better compression ratio, but with bad luck this can also make it worse. Decom- pressor memory usage is not affected, but compressor memory usage increases a little at preset levels -0 ... -3. Since there are two presets with dictionary sizes 4 MiB and 8 MiB, the presets -3e and -5e use slightly faster settings (lower CompCPU) than -4e and -6e, respectively. That way no two presets are identical. Preset DictSize CompCPU CompMem DecMem -0e 256 KiB 8 4 MiB 1 MiB -1e 1 MiB 8 13 MiB 2 MiB -2e 2 MiB 8 25 MiB 3 MiB -3e 4 MiB 7 48 MiB 5 MiB -4e 4 MiB 8 48 MiB 5 MiB -5e 8 MiB 7 94 MiB 9 MiB -6e 8 MiB 8 94 MiB 9 MiB -7e 16 MiB 8 186 MiB 17 MiB -8e 32 MiB 8 370 MiB 33 MiB -9e 64 MiB 8 674 MiB 65 MiB For example, there are a total of four presets that use 8 MiB dictionary, whose order from the fastest to the slowest is -5, -6, -5e, and -6e. --fast --best These are somewhat misleading aliases for -0 and -9, respec- tively. These are provided only for backwards compatibility with LZMA Utils. Avoid using these options. --block-size=size When compressing to the .xz format, split the input data into blocks of size bytes. The blocks are compressed independently from each other. --block-list=sizes When compressing to the .xz format, start a new block after the given intervals of uncompressed data. The uncompressed sizes of the blocks are specified as a comma- separated list. Omitting a size (two or more consecutive com- mas) is a shorthand to use the size of the previous block. If the input file is bigger than the sum of sizes, the last value in sizes is repeated until the end of the file. A special value of 0 may be used as the last value to indicate that the rest of the file should be encoded as a single block. If this option is used in threaded mode and one specifies sizes that exceed the encoder's block size (either the default value or the value specified with --block-size=size), the encoder will create additional blocks while keeping the boundaries specified in sizes. For example, if one specifies --threads=2 --block-size=10MiB --block-list=5MiB,10MiB,8MiB,12MiB,24MiB and the input file is 80 MiB, one will get 11 blocks: 5, 10, 8, 10, 2, 10, 10, 4, 10, 10, and 1 MiB. In single-threaded mode --block-size is ignored if --block-list is also specified. This might change before 5.2.0 is released. --flush-timeout=timeout When compressing, if more than timeout milliseconds (a positive integer) has passed since the previous flush and reading more input would block, all the pending input data is flushed from the encoder and made available in the output stream. This can be useful if xz is used to compress data that is streamed over a network. Small timeout values make the data available at the receiving end with a small delay, but large timeout values give better compression ratio. This feature is disabled by default. If this option is speci- fied more than once, the last one takes effect. The special timeout value of 0 can be used to explicitly disable this fea- ture. This feature is not available on non-POSIX systems. This feature is still experimental. Currently xz is unsuitable for decompressing the stream in real time due to how xz does buffering. --memlimit-compress=limit Set a memory usage limit for compression. If this option is specified multiple times, the last one takes effect. If the compression settings exceed the limit, xz will adjust the settings downwards so that the limit is no longer exceeded and display a notice that automatic adjustment was done. Such adjustments are not made when compressing with --format=raw or if --no-adjust has been specified. In those cases, an error is displayed and xz will exit with exit status 1. The limit can be specified in multiple ways: o The limit can be an absolute value in bytes. Using an inte- ger suffix like MiB can be useful. Example: --memlimit-com- press=80MiB o The limit can be specified as a percentage of total physical memory (RAM). This can be useful especially when setting the XZ_DEFAULTS environment variable in a shell initialization script that is shared between different computers. That way the limit is automatically bigger on systems with more mem- ory. Example: --memlimit-compress=70% o The limit can be reset back to its default value by setting it to 0. This is currently equivalent to setting the limit to max (no memory usage limit). Once multithreading support has been implemented, there may be a difference between 0 and max for the multithreaded case, so it is recommended to use 0 instead of max until the details have been decided. See also the section Memory usage. --memlimit-decompress=limit Set a memory usage limit for decompression. This also affects the --list mode. If the operation is not possible without exceeding the limit, xz will display an error and decompressing the file will fail. See --memlimit-compress=limit for possible ways to specify the limit. -M limit, --memlimit=limit, --memory=limit This is equivalent to specifying --memlimit-compress=limit --memlimit-decompress=limit. --no-adjust Display an error and exit if the compression settings exceed the memory usage limit. The default is to adjust the settings down- wards so that the memory usage limit is not exceeded. Automatic adjusting is always disabled when creating raw streams (--for- mat=raw). -T threads, --threads=threads Specify the number of worker threads to use. Setting threads to a special value 0 makes xz use as many threads as there are CPU cores on the system. The actual number of threads can be less than threads if the input file is not big enough for threading with the given settings or if using more threads would exceed the memory usage limit. Currently the only threading method is to split the input into blocks and compress them independently from each other. The default block size depends on the compression level and can be overriden with the --block-size=size option. It is possible that the details of this option change before the next stable XZ Utils release. This may include the meaning of the special value 0. Custom compressor filter chains A custom filter chain allows specifying the compression settings in detail instead of relying on the settings associated to the presets. When a custom filter chain is specified, preset options (-0 ... -9 and --extreme) earlier on the command line are forgotten. If a preset option is specified after one or more custom filter chain options, the new preset takes effect and the custom filter chain options specified earlier are forgotten. A filter chain is comparable to piping on the command line. When com- pressing, the uncompressed input goes to the first filter, whose output goes to the next filter (if any). The output of the last filter gets written to the compressed file. The maximum number of filters in the chain is four, but typically a filter chain has only one or two fil- ters. Many filters have limitations on where they can be in the filter chain: some filters can work only as the last filter in the chain, some only as a non-last filter, and some work in any position in the chain. Depending on the filter, this limitation is either inherent to the fil- ter design or exists to prevent security issues. A custom filter chain is specified by using one or more filter options in the order they are wanted in the filter chain. That is, the order of filter options is significant! When decoding raw streams (--for- mat=raw), the filter chain is specified in the same order as it was specified when compressing. Filters take filter-specific options as a comma-separated list. Extra commas in options are ignored. Every option has a default value, so you need to specify only those you want to change. To see the whole filter chain and options, use xz -vv (that is, use --verbose twice). This works also for viewing the filter chain options used by presets. --lzma1[=options] --lzma2[=options] Add LZMA1 or LZMA2 filter to the filter chain. These filters can be used only as the last filter in the chain. LZMA1 is a legacy filter, which is supported almost solely due to the legacy .lzma file format, which supports only LZMA1. LZMA2 is an updated version of LZMA1 to fix some practical issues of LZMA1. The .xz format uses LZMA2 and doesn't support LZMA1 at all. Compression speed and ratios of LZMA1 and LZMA2 are practically the same. LZMA1 and LZMA2 share the same set of options: preset=preset Reset all LZMA1 or LZMA2 options to preset. Preset con- sist of an integer, which may be followed by single-let- ter preset modifiers. The integer can be from 0 to 9, matching the command line options -0 ... -9. The only supported modifier is currently e, which matches --extreme. If no preset is specified, the default values of LZMA1 or LZMA2 options are taken from the preset 6. dict=size Dictionary (history buffer) size indicates how many bytes of the recently processed uncompressed data is kept in memory. The algorithm tries to find repeating byte sequences (matches) in the uncompressed data, and replace them with references to the data currently in the dictio- nary. The bigger the dictionary, the higher is the chance to find a match. Thus, increasing dictionary size usually improves compression ratio, but a dictionary big- ger than the uncompressed file is waste of memory. Typical dictionary size is from 64 KiB to 64 MiB. The minimum is 4 KiB. The maximum for compression is cur- rently 1.5 GiB (1536 MiB). The decompressor already sup- ports dictionaries up to one byte less than 4 GiB, which is the maximum for the LZMA1 and LZMA2 stream formats. Dictionary size and match finder (mf) together determine the memory usage of the LZMA1 or LZMA2 encoder. The same (or bigger) dictionary size is required for decompressing that was used when compressing, thus the memory usage of the decoder is determined by the dictionary size used when compressing. The .xz headers store the dictionary size either as 2^n or 2^n + 2^(n-1), so these sizes are somewhat preferred for compression. Other sizes will get rounded up when stored in the .xz headers. lc=lc Specify the number of literal context bits. The minimum is 0 and the maximum is 4; the default is 3. In addi- tion, the sum of lc and lp must not exceed 4. All bytes that cannot be encoded as matches are encoded as literals. That is, literals are simply 8-bit bytes that are encoded one at a time. The literal coding makes an assumption that the highest lc bits of the previous uncompressed byte correlate with the next byte. E.g. in typical English text, an upper- case letter is often followed by a lower-case letter, and a lower-case letter is usually followed by another lower- case letter. In the US-ASCII character set, the highest three bits are 010 for upper-case letters and 011 for lower-case letters. When lc is at least 3, the literal coding can take advantage of this property in the uncom- pressed data. The default value (3) is usually good. If you want maxi- mum compression, test lc=4. Sometimes it helps a little, and sometimes it makes compression worse. If it makes it worse, test e.g. lc=2 too. lp=lp Specify the number of literal position bits. The minimum is 0 and the maximum is 4; the default is 0. Lp affects what kind of alignment in the uncompressed data is assumed when encoding literals. See pb below for more information about alignment. pb=pb Specify the number of position bits. The minimum is 0 and the maximum is 4; the default is 2. Pb affects what kind of alignment in the uncompressed data is assumed in general. The default means four-byte alignment (2^pb=2^2=4), which is often a good choice when there's no better guess. When the aligment is known, setting pb accordingly may reduce the file size a little. E.g. with text files hav- ing one-byte alignment (US-ASCII, ISO-8859-*, UTF-8), setting pb=0 can improve compression slightly. For UTF-16 text, pb=1 is a good choice. If the alignment is an odd number like 3 bytes, pb=0 might be the best choice. Even though the assumed alignment can be adjusted with pb and lp, LZMA1 and LZMA2 still slightly favor 16-byte alignment. It might be worth taking into account when designing file formats that are likely to be often com- pressed with LZMA1 or LZMA2. mf=mf Match finder has a major effect on encoder speed, memory usage, and compression ratio. Usually Hash Chain match finders are faster than Binary Tree match finders. The default depends on the preset: 0 uses hc3, 1-3 use hc4, and the rest use bt4. The following match finders are supported. The memory usage formulas below are rough approximations, which are closest to the reality when dict is a power of two. hc3 Hash Chain with 2- and 3-byte hashing Minimum value for nice: 3 Memory usage: dict * 7.5 (if dict <= 16 MiB); dict * 5.5 + 64 MiB (if dict > 16 MiB) hc4 Hash Chain with 2-, 3-, and 4-byte hashing Minimum value for nice: 4 Memory usage: dict * 7.5 (if dict <= 32 MiB); dict * 6.5 (if dict > 32 MiB) bt2 Binary Tree with 2-byte hashing Minimum value for nice: 2 Memory usage: dict * 9.5 bt3 Binary Tree with 2- and 3-byte hashing Minimum value for nice: 3 Memory usage: dict * 11.5 (if dict <= 16 MiB); dict * 9.5 + 64 MiB (if dict > 16 MiB) bt4 Binary Tree with 2-, 3-, and 4-byte hashing Minimum value for nice: 4 Memory usage: dict * 11.5 (if dict <= 32 MiB); dict * 10.5 (if dict > 32 MiB) mode=mode Compression mode specifies the method to analyze the data produced by the match finder. Supported modes are fast and normal. The default is fast for presets 0-3 and nor- mal for presets 4-9. Usually fast is used with Hash Chain match finders and normal with Binary Tree match finders. This is also what the presets do. nice=nice Specify what is considered to be a nice length for a match. Once a match of at least nice bytes is found, the algorithm stops looking for possibly better matches. Nice can be 2-273 bytes. Higher values tend to give bet- ter compression ratio at the expense of speed. The default depends on the preset. depth=depth Specify the maximum search depth in the match finder. The default is the special value of 0, which makes the compressor determine a reasonable depth from mf and nice. Reasonable depth for Hash Chains is 4-100 and 16-1000 for Binary Trees. Using very high values for depth can make the encoder extremely slow with some files. Avoid set- ting the depth over 1000 unless you are prepared to interrupt the compression in case it is taking far too long. When decoding raw streams (--format=raw), LZMA2 needs only the dictionary size. LZMA1 needs also lc, lp, and pb. --x86[=options] --powerpc[=options] --ia64[=options] --arm[=options] --armthumb[=options] --sparc[=options] Add a branch/call/jump (BCJ) filter to the filter chain. These filters can be used only as a non-last filter in the filter chain. A BCJ filter converts relative addresses in the machine code to their absolute counterparts. This doesn't change the size of the data, but it increases redundancy, which can help LZMA2 to produce 0-15 % smaller .xz file. The BCJ filters are always reversible, so using a BCJ filter for wrong type of data doesn't cause any data loss, although it may make the compression ratio slightly worse. It is fine to apply a BCJ filter on a whole executable; there's no need to apply it only on the executable section. Applying a BCJ filter on an archive that contains both executable and non- executable files may or may not give good results, so it gener- ally isn't good to blindly apply a BCJ filter when compressing binary packages for distribution. These BCJ filters are very fast and use insignificant amount of memory. If a BCJ filter improves compression ratio of a file, it can improve decompression speed at the same time. This is because, on the same hardware, the decompression speed of LZMA2 is roughly a fixed number of bytes of compressed data per sec- ond. These BCJ filters have known problems related to the compression ratio: o Some types of files containing executable code (e.g. object files, static libraries, and Linux kernel modules) have the addresses in the instructions filled with filler values. These BCJ filters will still do the address conversion, which will make the compression worse with these files. o Applying a BCJ filter on an archive containing multiple simi- lar executables can make the compression ratio worse than not using a BCJ filter. This is because the BCJ filter doesn't detect the boundaries of the executable files, and doesn't reset the address conversion counter for each executable. Both of the above problems will be fixed in the future in a new filter. The old BCJ filters will still be useful in embedded systems, because the decoder of the new filter will be bigger and use more memory. Different instruction sets have have different alignment: Filter Alignment Notes x86 1 32-bit or 64-bit x86 PowerPC 4 Big endian only ARM 4 Little endian only ARM-Thumb 2 Little endian only IA-64 16 Big or little endian SPARC 4 Big or little endian Since the BCJ-filtered data is usually compressed with LZMA2, the compression ratio may be improved slightly if the LZMA2 options are set to match the alignment of the selected BCJ fil- ter. For example, with the IA-64 filter, it's good to set pb=4 with LZMA2 (2^4=16). The x86 filter is an exception; it's usu- ally good to stick to LZMA2's default four-byte alignment when compressing x86 executables. All BCJ filters support the same options: start=offset Specify the start offset that is used when converting between relative and absolute addresses. The offset must be a multiple of the alignment of the filter (see the ta- ble above). The default is zero. In practice, the default is good; specifying a custom offset is almost never useful. --delta[=options] Add the Delta filter to the filter chain. The Delta filter can be only used as a non-last filter in the filter chain. Currently only simple byte-wise delta calculation is supported. It can be useful when compressing e.g. uncompressed bitmap images or uncompressed PCM audio. However, special purpose algorithms may give significantly better results than Delta + LZMA2. This is true especially with audio, which compresses faster and better e.g. with flac(1). Supported options: dist=distance Specify the distance of the delta calculation in bytes. distance must be 1-256. The default is 1. For example, with dist=2 and eight-byte input A1 B1 A2 B3 A3 B5 A4 B7, the output will be A1 B1 01 02 01 02 01 02. Other options -q, --quiet Suppress warnings and notices. Specify this twice to suppress errors too. This option has no effect on the exit status. That is, even if a warning was suppressed, the exit status to indi- cate a warning is still used. -v, --verbose Be verbose. If standard error is connected to a terminal, xz will display a progress indicator. Specifying --verbose twice will give even more verbose output. The progress indicator shows the following information: o Completion percentage is shown if the size of the input file is known. That is, the percentage cannot be shown in pipes. o Amount of compressed data produced (compressing) or consumed (decompressing). o Amount of uncompressed data consumed (compressing) or pro- duced (decompressing). o Compression ratio, which is calculated by dividing the amount of compressed data processed so far by the amount of uncom- pressed data processed so far. o Compression or decompression speed. This is measured as the amount of uncompressed data consumed (compression) or pro- duced (decompression) per second. It is shown after a few seconds have passed since xz started processing the file. o Elapsed time in the format M:SS or H:MM:SS. o Estimated remaining time is shown only when the size of the input file is known and a couple of seconds have already passed since xz started processing the file. The time is shown in a less precise format which never has any colons, e.g. 2 min 30 s. When standard error is not a terminal, --verbose will make xz print the filename, compressed size, uncompressed size, compres- sion ratio, and possibly also the speed and elapsed time on a single line to standard error after compressing or decompressing the file. The speed and elapsed time are included only when the operation took at least a few seconds. If the operation didn't finish, e.g. due to user interruption, also the completion per- centage is printed if the size of the input file is known. -Q, --no-warn Don't set the exit status to 2 even if a condition worth a warn- ing was detected. This option doesn't affect the verbosity level, thus both --quiet and --no-warn have to be used to not display warnings and to not alter the exit status. --robot Print messages in a machine-parsable format. This is intended to ease writing frontends that want to use xz instead of liblzma, which may be the case with various scripts. The output with this option enabled is meant to be stable across xz releases. See the section ROBOT MODE for details. --info-memory Display, in human-readable format, how much physical memory (RAM) xz thinks the system has and the memory usage limits for compression and decompression, and exit successfully. -h, --help Display a help message describing the most commonly used options, and exit successfully. -H, --long-help Display a help message describing all features of xz, and exit successfully -V, --version Display the version number of xz and liblzma in human readable format. To get machine-parsable output, specify --robot before --version. ROBOT MODE The robot mode is activated with the --robot option. It makes the out- put of xz easier to parse by other programs. Currently --robot is sup- ported only together with --version, --info-memory, and --list. It will be supported for compression and decompression in the future. Version xz --robot --version will print the version number of xz and liblzma in the following format: XZ_VERSION=XYYYZZZS LIBLZMA_VERSION=XYYYZZZS X Major version. YYY Minor version. Even numbers are stable. Odd numbers are alpha or beta versions. ZZZ Patch level for stable releases or just a counter for develop- ment releases. S Stability. 0 is alpha, 1 is beta, and 2 is stable. S should be always 2 when YYY is even. XYYYZZZS are the same on both lines if xz and liblzma are from the same XZ Utils release. Examples: 4.999.9beta is 49990091 and 5.0.0 is 50000002. Memory limit information xz --robot --info-memory prints a single line with three tab-separated columns: 1. Total amount of physical memory (RAM) in bytes 2. Memory usage limit for compression in bytes. A special value of zero indicates the default setting, which for single-threaded mode is the same as no limit. 3. Memory usage limit for decompression in bytes. A special value of zero indicates the default setting, which for single-threaded mode is the same as no limit. In the future, the output of xz --robot --info-memory may have more columns, but never more than a single line. List mode xz --robot --list uses tab-separated output. The first column of every line has a string that indicates the type of the information found on that line: name This is always the first line when starting to list a file. The second column on the line is the filename. file This line contains overall information about the .xz file. This line is always printed after the name line. stream This line type is used only when --verbose was specified. There are as many stream lines as there are streams in the .xz file. block This line type is used only when --verbose was specified. There are as many block lines as there are blocks in the .xz file. The block lines are shown after all the stream lines; different line types are not interleaved. summary This line type is used only when --verbose was specified twice. This line is printed after all block lines. Like the file line, the summary line contains overall information about the .xz file. totals This line is always the very last line of the list output. It shows the total counts and sizes. The columns of the file lines: 2. Number of streams in the file 3. Total number of blocks in the stream(s) 4. Compressed size of the file 5. Uncompressed size of the file 6. Compression ratio, for example 0.123. If ratio is over 9.999, three dashes (---) are displayed instead of the ratio. 7. Comma-separated list of integrity check names. The follow- ing strings are used for the known check types: None, CRC32, CRC64, and SHA-256. For unknown check types, Unknown-N is used, where N is the Check ID as a decimal number (one or two digits). 8. Total size of stream padding in the file The columns of the stream lines: 2. Stream number (the first stream is 1) 3. Number of blocks in the stream 4. Compressed start offset 5. Uncompressed start offset 6. Compressed size (does not include stream padding) 7. Uncompressed size 8. Compression ratio 9. Name of the integrity check 10. Size of stream padding The columns of the block lines: 2. Number of the stream containing this block 3. Block number relative to the beginning of the stream (the first block is 1) 4. Block number relative to the beginning of the file 5. Compressed start offset relative to the beginning of the file 6. Uncompressed start offset relative to the beginning of the file 7. Total compressed size of the block (includes headers) 8. Uncompressed size 9. Compression ratio 10. Name of the integrity check If --verbose was specified twice, additional columns are included on the block lines. These are not displayed with a single --verbose, because getting this information requires many seeks and can thus be slow: 11. Value of the integrity check in hexadecimal 12. Block header size 13. Block flags: c indicates that compressed size is present, and u indicates that uncompressed size is present. If the flag is not set, a dash (-) is shown instead to keep the string length fixed. New flags may be added to the end of the string in the future. 14. Size of the actual compressed data in the block (this excludes the block header, block padding, and check fields) 15. Amount of memory (in bytes) required to decompress this block with this xz version 16. Filter chain. Note that most of the options used at com- pression time cannot be known, because only the options that are needed for decompression are stored in the .xz headers. The columns of the summary lines: 2. Amount of memory (in bytes) required to decompress this file with this xz version 3. yes or no indicating if all block headers have both com- pressed size and uncompressed size stored in them Since xz 5.1.2alpha: 4. Minimum xz version required to decompress the file The columns of the totals line: 2. Number of streams 3. Number of blocks 4. Compressed size 5. Uncompressed size 6. Average compression ratio 7. Comma-separated list of integrity check names that were present in the files 8. Stream padding size 9. Number of files. This is here to keep the order of the ear- lier columns the same as on file lines. If --verbose was specified twice, additional columns are included on the totals line: 10. Maximum amount of memory (in bytes) required to decompress the files with this xz version 11. yes or no indicating if all block headers have both com- pressed size and uncompressed size stored in them Since xz 5.1.2alpha: 12. Minimum xz version required to decompress the file Future versions may add new line types and new columns can be added to the existing line types, but the existing columns won't be changed. EXIT STATUS 0 All is good. 1 An error occurred. 2 Something worth a warning occurred, but no actual errors occurred. Notices (not warnings or errors) printed on standard error don't affect the exit status. ENVIRONMENT xz parses space-separated lists of options from the environment vari- ables XZ_DEFAULTS and XZ_OPT, in this order, before parsing the options from the command line. Note that only options are parsed from the environment variables; all non-options are silently ignored. Parsing is done with getopt_long(3) which is used also for the command line arguments. XZ_DEFAULTS User-specific or system-wide default options. Typically this is set in a shell initialization script to enable xz's memory usage limiter by default. Excluding shell initialization scripts and similar special cases, scripts must never set or unset XZ_DEFAULTS. XZ_OPT This is for passing options to xz when it is not possible to set the options directly on the xz command line. This is the case e.g. when xz is run by a script or tool, e.g. GNU tar(1): XZ_OPT=-2v tar caf foo.tar.xz foo Scripts may use XZ_OPT e.g. to set script-specific default com- pression options. It is still recommended to allow users to override XZ_OPT if that is reasonable, e.g. in sh(1) scripts one may use something like this: XZ_OPT=${XZ_OPT-"-7e"} export XZ_OPT LZMA UTILS COMPATIBILITY The command line syntax of xz is practically a superset of lzma, unlzma, and lzcat as found from LZMA Utils 4.32.x. In most cases, it is possible to replace LZMA Utils with XZ Utils without breaking exist- ing scripts. There are some incompatibilities though, which may some- times cause problems. Compression preset levels The numbering of the compression level presets is not identical in xz and LZMA Utils. The most important difference is how dictionary sizes are mapped to different presets. Dictionary size is roughly equal to the decompressor memory usage. Level xz LZMA Utils -0 256 KiB N/A -1 1 MiB 64 KiB -2 2 MiB 1 MiB -3 4 MiB 512 KiB -4 4 MiB 1 MiB -5 8 MiB 2 MiB -6 8 MiB 4 MiB -7 16 MiB 8 MiB -8 32 MiB 16 MiB -9 64 MiB 32 MiB The dictionary size differences affect the compressor memory usage too, but there are some other differences between LZMA Utils and XZ Utils, which make the difference even bigger: Level xz LZMA Utils 4.32.x -0 3 MiB N/A -1 9 MiB 2 MiB -2 17 MiB 12 MiB -3 32 MiB 12 MiB -4 48 MiB 16 MiB -5 94 MiB 26 MiB -6 94 MiB 45 MiB -7 186 MiB 83 MiB -8 370 MiB 159 MiB -9 674 MiB 311 MiB The default preset level in LZMA Utils is -7 while in XZ Utils it is -6, so both use an 8 MiB dictionary by default. Streamed vs. non-streamed .lzma files The uncompressed size of the file can be stored in the .lzma header. LZMA Utils does that when compressing regular files. The alternative is to mark that uncompressed size is unknown and use end-of-payload marker to indicate where the decompressor should stop. LZMA Utils uses this method when uncompressed size isn't known, which is the case for example in pipes. xz supports decompressing .lzma files with or without end-of-payload marker, but all .lzma files created by xz will use end-of-payload marker and have uncompressed size marked as unknown in the .lzma header. This may be a problem in some uncommon situations. For exam- ple, a .lzma decompressor in an embedded device might work only with files that have known uncompressed size. If you hit this problem, you need to use LZMA Utils or LZMA SDK to create .lzma files with known uncompressed size. Unsupported .lzma files The .lzma format allows lc values up to 8, and lp values up to 4. LZMA Utils can decompress files with any lc and lp, but always creates files with lc=3 and lp=0. Creating files with other lc and lp is possible with xz and with LZMA SDK. The implementation of the LZMA1 filter in liblzma requires that the sum of lc and lp must not exceed 4. Thus, .lzma files, which exceed this limitation, cannot be decompressed with xz. LZMA Utils creates only .lzma files which have a dictionary size of 2^n (a power of 2) but accepts files with any dictionary size. liblzma accepts only .lzma files which have a dictionary size of 2^n or 2^n + 2^(n-1). This is to decrease false positives when detecting .lzma files. These limitations shouldn't be a problem in practice, since practically all .lzma files have been compressed with settings that liblzma will accept. Trailing garbage When decompressing, LZMA Utils silently ignore everything after the first .lzma stream. In most situations, this is a bug. This also means that LZMA Utils don't support decompressing concatenated .lzma files. If there is data left after the first .lzma stream, xz considers the file to be corrupt unless --single-stream was used. This may break obscure scripts which have assumed that trailing garbage is ignored. NOTES Compressed output may vary The exact compressed output produced from the same uncompressed input file may vary between XZ Utils versions even if compression options are identical. This is because the encoder can be improved (faster or bet- ter compression) without affecting the file format. The output can vary even between different builds of the same XZ Utils version, if different build options are used. The above means that once --rsyncable has been implemented, the result- ing files won't necessarily be rsyncable unless both old and new files have been compressed with the same xz version. This problem can be fixed if a part of the encoder implementation is frozen to keep rsynca- ble output stable across xz versions. Embedded .xz decompressors Embedded .xz decompressor implementations like XZ Embedded don't neces- sarily support files created with integrity check types other than none and crc32. Since the default is --check=crc64, you must use --check=none or --check=crc32 when creating files for embedded systems. Outside embedded systems, all .xz format decompressors support all the check types, or at least are able to decompress the file without veri- fying the integrity check if the particular check is not supported. XZ Embedded supports BCJ filters, but only with the default start off- set. EXAMPLES Basics Compress the file foo into foo.xz using the default compression level (-6), and remove foo if compression is successful: xz foo Decompress bar.xz into bar and don't remove bar.xz even if decompres- sion is successful: xz -dk bar.xz Create baz.tar.xz with the preset -4e (-4 --extreme), which is slower than e.g. the default -6, but needs less memory for compression and decompression (48 MiB and 5 MiB, respectively): tar cf - baz | xz -4e > baz.tar.xz A mix of compressed and uncompressed files can be decompressed to stan- dard output with a single command: xz -dcf a.txt b.txt.xz c.txt d.txt.lzma > abcd.txt Parallel compression of many files On GNU and *BSD, find(1) and xargs(1) can be used to parallelize com- pression of many files: find . -type f \! -name '*.xz' -print0 \ | xargs -0r -P4 -n16 xz -T1 The -P option to xargs(1) sets the number of parallel xz processes. The best value for the -n option depends on how many files there are to be compressed. If there are only a couple of files, the value should probably be 1; with tens of thousands of files, 100 or even more may be appropriate to reduce the number of xz processes that xargs(1) will eventually create. The option -T1 for xz is there to force it to single-threaded mode, because xargs(1) is used to control the amount of parallelization. Robot mode Calculate how many bytes have been saved in total after compressing multiple files: xz --robot --list *.xz | awk '/^totals/{print $5-$4}' A script may want to know that it is using new enough xz. The follow- ing sh(1) script checks that the version number of the xz tool is at least 5.0.0. This method is compatible with old beta versions, which didn't support the --robot option: if ! eval "$(xz --robot --version 2> /dev/null)" || [ "$XZ_VERSION" -lt 50000002 ]; then echo "Your xz is too old." fi unset XZ_VERSION LIBLZMA_VERSION Set a memory usage limit for decompression using XZ_OPT, but if a limit has already been set, don't increase it: NEWLIM=$((123 << 20)) # 123 MiB OLDLIM=$(xz --robot --info-memory | cut -f3) if [ $OLDLIM -eq 0 -o $OLDLIM -gt $NEWLIM ]; then XZ_OPT="$XZ_OPT --memlimit-decompress=$NEWLIM" export XZ_OPT fi Custom compressor filter chains The simplest use for custom filter chains is customizing a LZMA2 pre- set. This can be useful, because the presets cover only a subset of the potentially useful combinations of compression settings. The CompCPU columns of the tables from the descriptions of the options -0 ... -9 and --extreme are useful when customizing LZMA2 presets. Here are the relevant parts collected from those two tables: Preset CompCPU -0 0 -1 1 -2 2 -3 3 -4 4 -5 5 -6 6 -5e 7 -6e 8 If you know that a file requires somewhat big dictionary (e.g. 32 MiB) to compress well, but you want to compress it quicker than xz -8 would do, a preset with a low CompCPU value (e.g. 1) can be modified to use a bigger dictionary: xz --lzma2=preset=1,dict=32MiB foo.tar With certain files, the above command may be faster than xz -6 while compressing significantly better. However, it must be emphasized that only some files benefit from a big dictionary while keeping the CompCPU value low. The most obvious situation, where a big dictionary can help a lot, is an archive containing very similar files of at least a few megabytes each. The dictionary size has to be significantly bigger than any individual file to allow LZMA2 to take full advantage of the similarities between consecutive files. If very high compressor and decompressor memory usage is fine, and the file being compressed is at least several hundred megabytes, it may be useful to use an even bigger dictionary than the 64 MiB that xz -9 would use: xz -vv --lzma2=dict=192MiB big_foo.tar Using -vv (--verbose --verbose) like in the above example can be useful to see the memory requirements of the compressor and decompressor. Remember that using a dictionary bigger than the size of the uncom- pressed file is waste of memory, so the above command isn't useful for small files. Sometimes the compression time doesn't matter, but the decompressor memory usage has to be kept low e.g. to make it possible to decompress the file on an embedded system. The following command uses -6e (-6 --extreme) as a base and sets the dictionary to only 64 KiB. The resulting file can be decompressed with XZ Embedded (that's why there is --check=crc32) using about 100 KiB of memory. xz --check=crc32 --lzma2=preset=6e,dict=64KiB foo If you want to squeeze out as many bytes as possible, adjusting the number of literal context bits (lc) and number of position bits (pb) can sometimes help. Adjusting the number of literal position bits (lp) might help too, but usually lc and pb are more important. E.g. a source code archive contains mostly US-ASCII text, so something like the following might give slightly (like 0.1 %) smaller file than xz -6e (try also without lc=4): xz --lzma2=preset=6e,pb=0,lc=4 source_code.tar Using another filter together with LZMA2 can improve compression with certain file types. E.g. to compress a x86-32 or x86-64 shared library using the x86 BCJ filter: xz --x86 --lzma2 libfoo.so Note that the order of the filter options is significant. If --x86 is specified after --lzma2, xz will give an error, because there cannot be any filter after LZMA2, and also because the x86 BCJ filter cannot be used as the last filter in the chain. The Delta filter together with LZMA2 can give good results with bitmap images. It should usually beat PNG, which has a few more advanced fil- ters than simple delta but uses Deflate for the actual compression. The image has to be saved in uncompressed format, e.g. as uncompressed TIFF. The distance parameter of the Delta filter is set to match the number of bytes per pixel in the image. E.g. 24-bit RGB bitmap needs dist=3, and it is also good to pass pb=0 to LZMA2 to accommodate the three-byte alignment: xz --delta=dist=3 --lzma2=pb=0 foo.tiff If multiple images have been put into a single archive (e.g. .tar), the Delta filter will work on that too as long as all images have the same number of bytes per pixel.

Preface This document describes the .lzma file format, which is sometimes also called LZMA_Alone format. It is a legacy file format, which is being or has been replaced by the .xz format. The MIME type of the .lzma format is `application/x-lzma'. The most commonly used software to handle .lzma files are LZMA SDK, LZMA Utils, 7-Zip, and XZ Utils. This document describes some of the differences between these implementations and gives hints what subset of the .lzma format is the most portable. 0.1. Notices and Acknowledgements This file format was designed by Igor Pavlov for use in LZMA SDK. This document was written by Lasse Collin using the documentation found from the LZMA SDK. This document has been put into the public domain. 0.2. Changes Last modified: 2011-04-12 11:55+0300 1. File Format +-+-+-+-+-+-+-+-+-+-+-+-+-+==========================+ | Header | LZMA Compressed Data | +-+-+-+-+-+-+-+-+-+-+-+-+-+==========================+ The .lzma format file consist of 13-byte Header followed by the LZMA Compressed Data. Unlike the .gz, .bz2, and .xz formats, it is not possible to concatenate multiple .lzma files as is and expect the decompression tool to decode the resulting file as if it were a single .lzma file. For example, the command line tools from LZMA Utils and LZMA SDK silently ignore all the data after the first .lzma stream. In contrast, the command line tool from XZ Utils considers the .lzma file to be corrupt if there is data after the first .lzma stream. 1.1. Header +------------+----+----+----+----+--+--+--+--+--+--+--+--+ | Properties | Dictionary Size | Uncompressed Size | +------------+----+----+----+----+--+--+--+--+--+--+--+--+ 1.1.1. Properties The Properties field contains three properties. An abbreviation is given in parentheses, followed by the value range of the property. The field consists of 1) the number of literal context bits (lc, [0, 8]); 2) the number of literal position bits (lp, [0, 4]); and 3) the number of position bits (pb, [0, 4]). The properties are encoded using the following formula: Properties = (pb * 5 + lp) * 9 + lc The following C code illustrates a straightforward way to decode the Properties field: uint8_t lc, lp, pb; uint8_t prop = get_lzma_properties(); if (prop > (4 * 5 + 4) * 9 + 8) return LZMA_PROPERTIES_ERROR; pb = prop / (9 * 5); prop -= pb * 9 * 5; lp = prop / 9; lc = prop - lp * 9; XZ Utils has an additional requirement: lc + lp <= 4. Files which don't follow this requirement cannot be decompressed with XZ Utils. Usually this isn't a problem since the most common lc/lp/pb values are 3/0/2. It is the only lc/lp/pb combination that the files created by LZMA Utils can have, but LZMA Utils can decompress files with any lc/lp/pb. 1.1.2. Dictionary Size Dictionary Size is stored as an unsigned 32-bit little endian integer. Any 32-bit value is possible, but for maximum portability, only sizes of 2^n and 2^n + 2^(n-1) should be used. LZMA Utils creates only files with dictionary size 2^n, 16 <= n <= 25. LZMA Utils can decompress files with any dictionary size. XZ Utils creates and decompresses .lzma files only with dictionary sizes 2^n and 2^n + 2^(n-1). If some other dictionary size is specified when compressing, the value stored in the Dictionary Size field is a rounded up, but the specified value is still used in the actual compression code. 1.1.3. Uncompressed Size Uncompressed Size is stored as unsigned 64-bit little endian integer. A special value of 0xFFFF_FFFF_FFFF_FFFF indicates that Uncompressed Size is unknown. End of Payload Marker (*) is used if and only if Uncompressed Size is unknown. XZ Utils rejects files whose Uncompressed Size field specifies a known size that is 256 GiB or more. This is to reject false positives when trying to guess if the input file is in the .lzma format. When Uncompressed Size is unknown, there is no limit for the uncompressed size of the file. (*) Some tools use the term End of Stream (EOS) marker instead of End of Payload Marker. 1.2. LZMA Compressed Data Detailed description of the format of this field is out of scope of this document. 2.

Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC-2119]. Indicating a warning means displaying a message, returning appropriate exit status, or doing something else to let the user know that something worth warning occurred. The operation SHOULD still finish if a warning is indicated. Indicating an error means displaying a message, returning appropriate exit status, or doing something else to let the user know that something prevented successfully finishing the operation. The operation MUST be aborted once an error has been indicated. 1.1. Byte and Its Representation In this document, byte is always 8 bits. A "null byte" has all bits unset. That is, the value of a null byte is 0x00. To represent byte blocks, this document uses notation that is similar to the notation used in [RFC-1952]: +-------+ | Foo | One byte. +-------+ +---+---+ | Foo | Two bytes; that is, some of the vertical bars +---+---+ can be missing. +=======+ | Foo | Zero or more bytes. +=======+ In this document, a boxed byte or a byte sequence declared using this notation is called "a field". The example field above would be called "the Foo field" or plain "Foo". If there are many fields, they may be split to multiple lines. This is indicated with an arrow ("--->"): +=====+ | Foo | +=====+ +=====+ ---> | Bar | +=====+ The above is equivalent to this: +=====+=====+ | Foo | Bar | +=====+=====+ 1.2. Multibyte Integers Multibyte integers of static length, such as CRC values, are stored in little endian byte order (least significant byte first). When smaller values are more likely than bigger values (for example file sizes), multibyte integers are encoded in a variable-length representation: - Numbers in the range [0, 127] are copied as is, and take one byte of space. - Bigger numbers will occupy two or more bytes. All but the last byte of the multibyte representation have the highest (eighth) bit set. For now, the value of the variable-length integers is limited to 63 bits, which limits the encoded size of the integer to nine bytes. These limits may be increased in the future if needed. The following C code illustrates encoding and decoding of variable-length integers. The functions return the number of bytes occupied by the integer (1-9), or zero on error. #include #include size_t encode(uint8_t buf[static 9], uint64_t num) { if (num > UINT64_MAX / 2) return 0; size_t i = 0; while (num >= 0x80) { buf[i++] = (uint8_t)(num) | 0x80; num >>= 7; } buf[i++] = (uint8_t)(num); return i; } size_t decode(const uint8_t buf[], size_t size_max, uint64_t *num) { if (size_max == 0) return 0; if (size_max > 9) size_max = 9; *num = buf[0] & 0x7F; size_t i = 0; while (buf[i++] & 0x80) { if (i >= size_max || buf[i] == 0x00) return 0; *num |= (uint64_t)(buf[i] & 0x7F) << (i * 7); } return i; } 2. Overall Structure of .xz File A standalone .xz files consist of one or more Streams which may have Stream Padding between or after them: +========+================+========+================+ | Stream | Stream Padding | Stream | Stream Padding | ... +========+================+========+================+ The sizes of Stream and Stream Padding are always multiples of four bytes, thus the size of every valid .xz file MUST be a multiple of four bytes. While a typical file contains only one Stream and no Stream Padding, a decoder handling standalone .xz files SHOULD support files that have more than one Stream or Stream Padding. In contrast to standalone .xz files, when the .xz file format is used as an internal part of some other file format or communication protocol, it usually is expected that the decoder stops after the first Stream, and doesn't look for Stream Padding or possibly other Streams. 2.1. Stream +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+ +=======+ | Stream Header | Block | Block | ... | Block | +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+ +=======+ +=======+-+-+-+-+-+-+-+-+-+-+-+-+ ---> | Index | Stream Footer | +=======+-+-+-+-+-+-+-+-+-+-+-+-+ All the above fields have a size that is a multiple of four. If Stream is used as an internal part of another file format, it is RECOMMENDED to make the Stream start at an offset that is a multiple of four bytes. Stream Header, Index, and Stream Footer are always present in a Stream. The maximum size of the Index field is 16 GiB (2^34). There are zero or more Blocks. The maximum number of Blocks is limited only by the maximum size of the Index field. Total size of a Stream MUST be less than 8 EiB (2^63 bytes). The same limit applies to the total amount of uncompressed data stored in a Stream. If an implementation supports handling .xz files with multiple concatenated Streams, it MAY apply the above limits to the file as a whole instead of limiting per Stream basis. 2.1.1. Stream Header +---+---+---+---+---+---+-------+------+--+--+--+--+ | Header Magic Bytes | Stream Flags | CRC32 | +---+---+---+---+---+---+-------+------+--+--+--+--+ 2.1.1.1. Header Magic Bytes The first six (6) bytes of the Stream are so called Header Magic Bytes. They can be used to identify the file type. Using a C array and ASCII: const uint8_t HEADER_MAGIC[6] = { 0xFD, '7', 'z', 'X', 'Z', 0x00 }; In plain hexadecimal: FD 37 7A 58 5A 00 Notes: - The first byte (0xFD) was chosen so that the files cannot be erroneously detected as being in .lzma format, in which the first byte is in the range [0x00, 0xE0]. - The sixth byte (0x00) was chosen to prevent applications from misdetecting the file as a text file. If the Header Magic Bytes don't match, the decoder MUST indicate an error. 2.1.1.2. Stream Flags The first byte of Stream Flags is always a null byte. In the future, this byte may be used to indicate a new Stream version or other Stream properties. The second byte of Stream Flags is a bit field: Bit(s) Mask Description 0-3 0x0F Type of Check (see Section 3.4): ID Size Check name 0x00 0 bytes None 0x01 4 bytes CRC32 0x02 4 bytes (Reserved) 0x03 4 bytes (Reserved) 0x04 8 bytes CRC64 0x05 8 bytes (Reserved) 0x06 8 bytes (Reserved) 0x07 16 bytes (Reserved) 0x08 16 bytes (Reserved) 0x09 16 bytes (Reserved) 0x0A 32 bytes SHA-256 0x0B 32 bytes (Reserved) 0x0C 32 bytes (Reserved) 0x0D 64 bytes (Reserved) 0x0E 64 bytes (Reserved) 0x0F 64 bytes (Reserved) 4-7 0xF0 Reserved for future use; MUST be zero for now. Implementations SHOULD support at least the Check IDs 0x00 (None) and 0x01 (CRC32). Supporting other Check IDs is OPTIONAL. If an unsupported Check is used, the decoder SHOULD indicate a warning or error. If any reserved bit is set, the decoder MUST indicate an error. It is possible that there is a new field present which the decoder is not aware of, and can thus parse the Stream Header incorrectly. 2.1.1.3. CRC32 The CRC32 is calculated from the Stream Flags field. It is stored as an unsigned 32-bit little endian integer. If the calculated value does not match the stored one, the decoder MUST indicate an error. The idea is that Stream Flags would always be two bytes, even if new features are needed. This way old decoders will be able to verify the CRC32 calculated from Stream Flags, and thus distinguish between corrupt files (CRC32 doesn't match) and files that the decoder doesn't support (CRC32 matches but Stream Flags has reserved bits set). 2.1.2. Stream Footer +-+-+-+-+---+---+---+---+-------+------+----------+---------+ | CRC32 | Backward Size | Stream Flags | Footer Magic Bytes | +-+-+-+-+---+---+---+---+-------+------+----------+---------+ 2.1.2.1. CRC32 The CRC32 is calculated from the Backward Size and Stream Flags fields. It is stored as an unsigned 32-bit little endian integer. If the calculated value does not match the stored one, the decoder MUST indicate an error. The reason to have the CRC32 field before the Backward Size and Stream Flags fields is to keep the four-byte fields aligned to a multiple of four bytes. 2.1.2.2. Backward Size Backward Size is stored as a 32-bit little endian integer, which indicates the size of the Index field as multiple of four bytes, minimum value being four bytes: real_backward_size = (stored_backward_size + 1) * 4; If the stored value does not match the real size of the Index field, the decoder MUST indicate an error. Using a fixed-size integer to store Backward Size makes it slightly simpler to parse the Stream Footer when the application needs to parse the Stream backwards. 2.1.2.3. Stream Flags This is a copy of the Stream Flags field from the Stream Header. The information stored to Stream Flags is needed when parsing the Stream backwards. The decoder MUST compare the Stream Flags fields in both Stream Header and Stream Footer, and indicate an error if they are not identical. 2.1.2.4. Footer Magic Bytes As the last step of the decoding process, the decoder MUST verify the existence of Footer Magic Bytes. If they don't match, an error MUST be indicated. Using a C array and ASCII: const uint8_t FOOTER_MAGIC[2] = { 'Y', 'Z' }; In hexadecimal: 59 5A The primary reason to have Footer Magic Bytes is to make it easier to detect incomplete files quickly, without uncompressing. If the file does not end with Footer Magic Bytes (excluding Stream Padding described in Section 2.2), it cannot be undamaged, unless someone has intentionally appended garbage after the end of the Stream. 2.2. Stream Padding Only the decoders that support decoding of concatenated Streams MUST support Stream Padding. Stream Padding MUST contain only null bytes. To preserve the four-byte alignment of consecutive Streams, the size of Stream Padding MUST be a multiple of four bytes. Empty Stream Padding is allowed. If these requirements are not met, the decoder MUST indicate an error. Note that non-empty Stream Padding is allowed at the end of the file; there doesn't need to be a new Stream after non-empty Stream Padding. This can be convenient in certain situations [GNU-tar]. The possibility of Stream Padding MUST be taken into account when designing an application that parses Streams backwards, and the application supports concatenated Streams. 3. Block +==============+=================+===============+=======+ | Block Header | Compressed Data | Block Padding | Check | +==============+=================+===============+=======+ 3.1. Block Header +-------------------+-------------+=================+ | Block Header Size | Block Flags | Compressed Size | +-------------------+-------------+=================+ +===================+======================+ ---> | Uncompressed Size | List of Filter Flags | +===================+======================+ +================+--+--+--+--+ ---> | Header Padding | CRC32 | +================+--+--+--+--+ 3.1.1. Block Header Size This field overlaps with the Index Indicator field (see Section 4.1). This field contains the size of the Block Header field, including the Block Header Size field itself. Valid values are in the range [0x01, 0xFF], which indicate the size of the Block Header as multiples of four bytes, minimum size being eight bytes: real_header_size = (encoded_header_size + 1) * 4; If a Block Header bigger than 1024 bytes is needed in the future, a new field can be added between the Block Header and Compressed Data fields. The presence of this new field would be indicated in the Block Header field. 3.1.2. Block Flags The Block Flags field is a bit field: Bit(s) Mask Description 0-1 0x03 Number of filters (1-4) 2-5 0x3C Reserved for future use; MUST be zero for now. 6 0x40 The Compressed Size field is present. 7 0x80 The Uncompressed Size field is present. If any reserved bit is set, the decoder MUST indicate an error. It is possible that there is a new field present which the decoder is not aware of, and can thus parse the Block Header incorrectly. 3.1.3. Compressed Size This field is present only if the appropriate bit is set in the Block Flags field (see Section 3.1.2). The Compressed Size field contains the size of the Compressed Data field, which MUST be non-zero. Compressed Size is stored using the encoding described in Section 1.2. If the Compressed Size doesn't match the size of the Compressed Data field, the decoder MUST indicate an error. 3.1.4. Uncompressed Size This field is present only if the appropriate bit is set in the Block Flags field (see Section 3.1.2). The Uncompressed Size field contains the size of the Block after uncompressing. Uncompressed Size is stored using the encoding described in Section 1.2. If the Uncompressed Size does not match the real uncompressed size, the decoder MUST indicate an error. Storing the Compressed Size and Uncompressed Size fields serves several purposes: - The decoder knows how much memory it needs to allocate for a temporary buffer in multithreaded mode. - Simple error detection: wrong size indicates a broken file. - Seeking forwards to a specific location in streamed mode. It should be noted that the only reliable way to determine the real uncompressed size is to uncompress the Block, because the Block Header and Index fields may contain (intentionally or unintentionally) invalid information. 3.1.5. List of Filter Flags +================+================+ +================+ | Filter 0 Flags | Filter 1 Flags | ... | Filter n Flags | +================+================+ +================+ The number of Filter Flags fields is stored in the Block Flags field (see Section 3.1.2). The format of each Filter Flags field is as follows: +===========+====================+===================+ | Filter ID | Size of Properties | Filter Properties | +===========+====================+===================+ Both Filter ID and Size of Properties are stored using the encoding described in Section 1.2. Size of Properties indicates the size of the Filter Properties field as bytes. The list of officially defined Filter IDs and the formats of their Filter Properties are described in Section 5.3. Filter IDs greater than or equal to 0x4000_0000_0000_0000 (2^62) are reserved for implementation-specific internal use. These Filter IDs MUST never be used in List of Filter Flags. 3.1.6. Header Padding This field contains as many null byte as it is needed to make the Block Header have the size specified in Block Header Size. If any of the bytes are not null bytes, the decoder MUST indicate an error. It is possible that there is a new field present which the decoder is not aware of, and can thus parse the Block Header incorrectly. 3.1.7. CRC32 The CRC32 is calculated over everything in the Block Header field except the CRC32 field itself. It is stored as an unsigned 32-bit little endian integer. If the calculated value does not match the stored one, the decoder MUST indicate an error. By verifying the CRC32 of the Block Header before parsing the actual contents allows the decoder to distinguish between corrupt and unsupported files. 3.2. Compressed Data The format of Compressed Data depends on Block Flags and List of Filter Flags. Excluding the descriptions of the simplest filters in Section 5.3, the format of the filter-specific encoded data is out of scope of this document. 3.3. Block Padding Block Padding MUST contain 0-3 null bytes to make the size of the Block a multiple of four bytes. This can be needed when the size of Compressed Data is not a multiple of four. If any of the bytes in Block Padding are not null bytes, the decoder MUST indicate an error. 3.4. Check The type and size of the Check field depends on which bits are set in the Stream Flags field (see Section 2.1.1.2). The Check, when used, is calculated from the original uncompressed data. If the calculated Check does not match the stored one, the decoder MUST indicate an error. If the selected type of Check is not supported by the decoder, it SHOULD indicate a warning or error. 4. Index +-----------------+===================+ | Index Indicator | Number of Records | +-----------------+===================+ +=================+===============+-+-+-+-+ ---> | List of Records | Index Padding | CRC32 | +=================+===============+-+-+-+-+ Index serves several purposes. Using it, one can - verify that all Blocks in a Stream have been processed; - find out the uncompressed size of a Stream; and - quickly access the beginning of any Block (random access). 4.1. Index Indicator This field overlaps with the Block Header Size field (see Section 3.1.1). The value of Index Indicator is always 0x00. 4.2. Number of Records This field indicates how many Records there are in the List of Records field, and thus how many Blocks there are in the Stream. The value is stored using the encoding described in Section 1.2. If the decoder has decoded all the Blocks of the Stream, and then notices that the Number of Records doesn't match the real number of Blocks, the decoder MUST indicate an error. 4.3. List of Records List of Records consists of as many Records as indicated by the Number of Records field: +========+========+ | Record | Record | ... +========+========+ Each Record contains information about one Block: +===============+===================+ | Unpadded Size | Uncompressed Size | +===============+===================+ If the decoder has decoded all the Blocks of the Stream, it MUST verify that the contents of the Records match the real Unpadded Size and Uncompressed Size of the respective Blocks. Implementation hint: It is possible to verify the Index with constant memory usage by calculating for example SHA-256 of both the real size values and the List of Records, then comparing the hash values. Implementing this using non-cryptographic hash like CRC32 SHOULD be avoided unless small code size is important. If the decoder supports random-access reading, it MUST verify that Unpadded Size and Uncompressed Size of every completely decoded Block match the sizes stored in the Index. If only partial Block is decoded, the decoder MUST verify that the processed sizes don't exceed the sizes stored in the Index. 4.3.1. Unpadded Size This field indicates the size of the Block excluding the Block Padding field. That is, Unpadded Size is the size of the Block Header, Compressed Data, and Check fields. Unpadded Size is stored using the encoding described in Section 1.2. The value MUST never be zero; with the current structure of Blocks, the actual minimum value for Unpadded Size is five. Implementation note: Because the size of the Block Padding field is not included in Unpadded Size, calculating the total size of a Stream or doing random-access reading requires calculating the actual size of the Blocks by rounding Unpadded Sizes up to the next multiple of four. The reason to exclude Block Padding from Unpadded Size is to ease making a raw copy of Compressed Data without Block Padding. This can be useful, for example, if someone wants to convert Streams to some other file format quickly. 4.3.2. Uncompressed Size This field indicates the Uncompressed Size of the respective Block as bytes. The value is stored using the encoding described in Section 1.2. 4.4. Index Padding This field MUST contain 0-3 null bytes to pad the Index to a multiple of four bytes. If any of the bytes are not null bytes, the decoder MUST indicate an error. 4.5. CRC32 The CRC32 is calculated over everything in the Index field except the CRC32 field itself. The CRC32 is stored as an unsigned 32-bit little endian integer. If the calculated value does not match the stored one, the decoder MUST indicate an error. 5. Filter Chains The Block Flags field defines how many filters are used. When more than one filter is used, the filters are chained; that is, the output of one filter is the input of another filter. The following figure illustrates the direction of data flow. v Uncompressed Data ^ | Filter 0 | Encoder | Filter 1 | Decoder | Filter n | v Compressed Data ^ 5.1. Alignment Alignment of uncompressed input data is usually the job of the application producing the data. For example, to get the best results, an archiver tool should make sure that all PowerPC executable files in the archive stream start at offsets that are multiples of four bytes. Some filters, for example LZMA2, can be configured to take advantage of specified alignment of input data. Note that taking advantage of aligned input can be beneficial also when a filter is not the first filter in the chain. For example, if you compress PowerPC executables, you may want to use the PowerPC filter and chain that with the LZMA2 filter. Because not only the input but also the output alignment of the PowerPC filter is four bytes, it is now beneficial to set LZMA2 settings so that the LZMA2 encoder can take advantage of its four-byte-aligned input data. The output of the last filter in the chain is stored to the Compressed Data field, which is is guaranteed to be aligned to a multiple of four bytes relative to the beginning of the Stream. This can increase - speed, if the filtered data is handled multiple bytes at a time by the filter-specific encoder and decoder, because accessing aligned data in computer memory is usually faster; and - compression ratio, if the output data is later compressed with an external compression tool. 5.2. Security If filters would be allowed to be chained freely, it would be possible to create malicious files, that would be very slow to decode. Such files could be used to create denial of service attacks. Slow files could occur when multiple filters are chained: v Compressed input data | Filter 1 decoder (last filter) | Filter 0 decoder (non-last filter) v Uncompressed output data The decoder of the last filter in the chain produces a lot of output from little input. Another filter in the chain takes the output of the last filter, and produces very little output while consuming a lot of input. As a result, a lot of data is moved inside the filter chain, but the filter chain as a whole gets very little work done. To prevent this kind of slow files, there are restrictions on how the filters can be chained. These restrictions MUST be taken into account when designing new filters. The maximum number of filters in the chain has been limited to four, thus there can be at maximum of three non-last filters. Of these three non-last filters, only two are allowed to change the size of the data. The non-last filters, that change the size of the data, MUST have a limit how much the decoder can compress the data: the decoder SHOULD produce at least n bytes of output when the filter is given 2n bytes of input. This limit is not absolute, but significant deviations MUST be avoided. The above limitations guarantee that if the last filter in the chain produces 4n bytes of output, the chain as a whole will produce at least n bytes of output. 5.3. Filters 5.3.1. LZMA2 LZMA (Lempel-Ziv-Markov chain-Algorithm) is a general-purpose compression algorithm with high compression ratio and fast decompression. LZMA is based on LZ77 and range coding algorithms. LZMA2 is an extension on top of the original LZMA. LZMA2 uses LZMA internally, but adds support for flushing the encoder, uncompressed chunks, eases stateful decoder implementations, and improves support for multithreading. Thus, the plain LZMA will not be supported in this file format. Filter ID: 0x21 Size of Filter Properties: 1 byte Changes size of data: Yes Allow as a non-last filter: No Allow as the last filter: Yes Preferred alignment: Input data: Adjustable to 1/2/4/8/16 byte(s) Output data: 1 byte The format of the one-byte Filter Properties field is as follows: Bits Mask Description 0-5 0x3F Dictionary Size 6-7 0xC0 Reserved for future use; MUST be zero for now. Dictionary Size is encoded with one-bit mantissa and five-bit exponent. The smallest dictionary size is 4 KiB and the biggest is 4 GiB. Raw value Mantissa Exponent Dictionary size 0 2 11 4 KiB 1 3 11 6 KiB 2 2 12 8 KiB 3 3 12 12 KiB 4 2 13 16 KiB 5 3 13 24 KiB 6 2 14 32 KiB ... ... ... ... 35 3 27 768 MiB 36 2 28 1024 MiB 37 3 29 1536 MiB 38 2 30 2048 MiB 39 3 30 3072 MiB 40 2 31 4096 MiB - 1 B Instead of having a table in the decoder, the dictionary size can be decoded using the following C code: const uint8_t bits = get_dictionary_flags() & 0x3F; if (bits > 40) return DICTIONARY_TOO_BIG; // Bigger than 4 GiB uint32_t dictionary_size; if (bits == 40) { dictionary_size = UINT32_MAX; } else { dictionary_size = 2 | (bits & 1); dictionary_size <<= bits / 2 + 11; } 5.3.2. Branch/Call/Jump Filters for Executables These filters convert relative branch, call, and jump instructions to their absolute counterparts in executable files. This conversion increases redundancy and thus compression ratio. Size of Filter Properties: 0 or 4 bytes Changes size of data: No Allow as a non-last filter: Yes Allow as the last filter: No Below is the list of filters in this category. The alignment is the same for both input and output data. Filter ID Alignment Description 0x04 1 byte x86 filter (BCJ) 0x05 4 bytes PowerPC (big endian) filter 0x06 16 bytes IA64 filter 0x07 4 bytes ARM (little endian) filter 0x08 2 bytes ARM Thumb (little endian) filter 0x09 4 bytes SPARC filter If the size of Filter Properties is four bytes, the Filter Properties field contains the start offset used for address conversions. It is stored as an unsigned 32-bit little endian integer. The start offset MUST be a multiple of the alignment of the filter as listed in the table above; if it isn't, the decoder MUST indicate an error. If the size of Filter Properties is zero, the start offset is zero. Setting the start offset may be useful if an executable has multiple sections, and there are many cross-section calls. Taking advantage of this feature usually requires usage of the Subblock filter, whose design is not complete yet. 5.3.3. Delta The Delta filter may increase compression ratio when the value of the next byte correlates with the value of an earlier byte at specified distance. Filter ID: 0x03 Size of Filter Properties: 1 byte Changes size of data: No Allow as a non-last filter: Yes Allow as the last filter: No Preferred alignment: Input data: 1 byte Output data: Same as the original input data The Properties byte indicates the delta distance, which can be 1-256 bytes backwards from the current byte: 0x00 indicates distance of 1 byte and 0xFF distance of 256 bytes. 5.3.3.1. Format of the Encoded Output The code below illustrates both encoding and decoding with the Delta filter. // Distance is in the range [1, 256]. const unsigned int distance = get_properties_byte() + 1; uint8_t pos = 0; uint8_t delta[256]; memset(delta, 0, sizeof(delta)); while (1) { const int byte = read_byte(); if (byte == EOF) break; uint8_t tmp = delta[(uint8_t)(distance + pos)]; if (is_encoder) { tmp = (uint8_t)(byte) - tmp; delta[pos] = (uint8_t)(byte); } else { tmp = (uint8_t)(byte) + tmp; delta[pos] = tmp; } write_byte(tmp); --pos; } 5.4. Custom Filter IDs If a developer wants to use custom Filter IDs, he has two choices. The first choice is to contact Lasse Collin and ask him to allocate a range of IDs for the developer. The second choice is to generate a 40-bit random integer, which the developer can use as his personal Developer ID. To minimize the risk of collisions, Developer ID has to be a randomly generated integer, not manually selected "hex word". The following command, which works on many free operating systems, can be used to generate Developer ID: dd if=/dev/urandom bs=5 count=1 | hexdump The developer can then use his Developer ID to create unique (well, hopefully unique) Filter IDs. Bits Mask Description 0-15 0x0000_0000_0000_FFFF Filter ID 16-55 0x00FF_FFFF_FFFF_0000 Developer ID 56-62 0x3F00_0000_0000_0000 Static prefix: 0x3F The resulting 63-bit integer will use 9 bytes of space when stored using the encoding described in Section 1.2. To get a shorter ID, see the beginning of this Section how to request a custom ID range. 5.4.1. Reserved Custom Filter ID Ranges Range Description 0x0000_0300 - 0x0000_04FF Reserved to ease .7z compatibility 0x0002_0000 - 0x0007_FFFF Reserved to ease .7z compatibility 0x0200_0000 - 0x07FF_FFFF Reserved to ease .7z compatibility 6. Cyclic Redundancy Checks There are several incompatible variations to calculate CRC32 and CRC64. For simplicity and clarity, complete examples are provided to calculate the checks as they are used in this file format. Implementations MAY use different code as long as it gives identical results. The program below reads data from standard input, calculates the CRC32 and CRC64 values, and prints the calculated values as big endian hexadecimal strings to standard output. #include #include #include uint32_t crc32_table[256]; uint64_t crc64_table[256]; void init(void) { static const uint32_t poly32 = UINT32_C(0xEDB88320); static const uint64_t poly64 = UINT64_C(0xC96C5795D7870F42); for (size_t i = 0; i < 256; ++i) { uint32_t crc32 = i; uint64_t crc64 = i; for (size_t j = 0; j < 8; ++j) { if (crc32 & 1) crc32 = (crc32 >> 1) ^ poly32; else crc32 >>= 1; if (crc64 & 1) crc64 = (crc64 >> 1) ^ poly64; else crc64 >>= 1; } crc32_table[i] = crc32; crc64_table[i] = crc64; } } uint32_t crc32(const uint8_t *buf, size_t size, uint32_t crc) { crc = ~crc; for (size_t i = 0; i < size; ++i) crc = crc32_table[buf[i] ^ (crc & 0xFF)] ^ (crc >> 8); return ~crc; } uint64_t crc64(const uint8_t *buf, size_t size, uint64_t crc) { crc = ~crc; for (size_t i = 0; i < size; ++i) crc = crc64_table[buf[i] ^ (crc & 0xFF)] ^ (crc >> 8); return ~crc; } int main() { init(); uint32_t value32 = 0; uint64_t value64 = 0; uint64_t total_size = 0; uint8_t buf[8192]; while (1) { const size_t buf_size = fread(buf, 1, sizeof(buf), stdin); if (buf_size == 0) break; total_size += buf_size; value32 = crc32(buf, buf_size, value32); value64 = crc64(buf, buf_size, value64); } printf("Bytes: %" PRIu64 "\n", total_size); printf("CRC-32: 0x%08" PRIX32 "\n", value32); printf("CRC-64: 0x%016" PRIX64 "\n", value64); return 0; } 7.

One of the project's goals was to fit the distro on a single 700 MiB ISO-9660 image. Using LZMA instead of gzip helped a lot. Roughly speaking, one could fit data that took 1000 MiB in gzipped form into 700 MiB with LZMA. Naturally, the compression ratio varied across packages, but this was what we got on average. Slackware packages have traditionally had .tgz as the filename suffix, which is an abbreviation of .tar.gz. A logical naming for LZMA compressed packages was .tlz, being an abbreviation of .tar.lzma. At the end of the year 2007, there was no distribution under the Tukaani project anymore, but development of LZMA Utils was kept going. Still, there were .tlz packages around, because at least Vector Linux (a Slackware based distribution) used LZMA for its packages. First versions of the modified pkgtools used the LZMA_Alone tool from Igor Pavlov's LZMA SDK as is. It was fine, because users wouldn't need to interact with LZMA_Alone directly. But people soon wanted to use LZMA for other files too, and the interface of LZMA_Alone wasn't comfortable for those used to gzip and bzip2. First steps of LZMA Utils The first version of LZMA Utils (4.22.0) included a shell script called lzmash. It was a wrapper that had a gzip-like command-line interface. It used the LZMA_Alone tool from LZMA SDK to do all the real work. zgrep, zdiff, and related scripts from gzip were adapted to work with LZMA and were part of the first LZMA Utils release too. LZMA Utils 4.22.0 included also lzmadec, which was a small (less than 10 KiB) decoder-only command-line tool. It was written on top of the decoder-only C code found from the LZMA SDK. lzmadec was convenient in situations where LZMA_Alone (a few hundred KiB) would be too big. lzmash and lzmadec were written by Lasse Collin. Second generation The lzmash script was an ugly and not very secure hack. The last version of LZMA Utils to use lzmash was 4.27.1. LZMA Utils 4.32.0beta1 introduced a new lzma command-line tool written by Ville Koskinen. It was written in C++, and used the encoder and decoder from C++ LZMA SDK with some little modifications. This tool replaced both the lzmash script and the LZMA_Alone command-line tool in LZMA Utils. Introducing this new tool caused some temporary incompatibilities, because the LZMA_Alone executable was simply named lzma like the new command-line tool, but they had a completely different command-line interface. The file format was still the same. Lasse wrote liblzmadec, which was a small decoder-only library based on the C code found from LZMA SDK. liblzmadec had an API similar to zlib, although there were some significant differences, which made it non-trivial to use it in some applications designed for zlib and libbzip2. The lzmadec command-line tool was converted to use liblzmadec. Alexandre Sauvé helped converting the build system to use GNU Autotools. This made it easier to test for certain less portable features needed by the new command-line tool. Since the new command-line tool never got completely finished (for example, it didn't support the LZMA_OPT environment variable), the intent was to not call 4.32.x stable. Similarly, liblzmadec wasn't polished, but appeared to work well enough, so some people started using it too. Because the development of the third generation of LZMA Utils was delayed considerably (3-4 years), the 4.32.x branch had to be kept maintained. It got some bug fixes now and then, and finally it was decided to call it stable, although most of the missing features were never added. File format problems The file format used by LZMA_Alone was primitive. It was designed with embedded systems in mind, and thus provided only a minimal set of features. The two biggest problems for non-embedded use were the lack of magic bytes and an integrity check. Igor and Lasse started developing a new file format with some help from Ville Koskinen. Also Mark Adler, Mikko Pouru, H. Peter Anvin, and Lars Wirzenius helped with some minor things at some point of the development. Designing the new format took quite a long time (actually, too long a time would be a more appropriate expression). It was mostly because Lasse was quite slow at getting things done due to personal reasons. Originally the new format was supposed to use the same .lzma suffix that was already used by the old file format. Switching to the new format wouldn't have caused much trouble when the old format wasn't used by many people. But since the development of the new format took such a long time, the old format got quite popular, and it was decided that the new file format must use a different suffix. It was decided to use .xz as the suffix of the new file format. The first stable .xz file format specification was finally released in December 2008. In addition to fixing the most obvious problems of the old .lzma format, the .xz format added some new features like support for multiple filters (compression algorithms), filter chaining (like piping on the command line), and limited random-access reading. Currently the primary compression algorithm used in .xz is LZMA2. It is an extension on top of the original LZMA to fix some practical problems: LZMA2 adds support for flushing the encoder, uncompressed chunks, eases stateful decoder implementations, and improves support for multithreading. Since LZMA2 is better than the original LZMA, the original LZMA is not supported in .xz. Transition to XZ Utils The early versions of XZ Utils were called LZMA Utils. The first releases were 4.42.0alphas. They dropped the rest of the C++ LZMA SDK. The code was still directly based on LZMA SDK but ported to C and converted from a callback API to a stateful API. Later, Igor Pavlov made a C version of the LZMA encoder too; these ports from C++ to C were independent in LZMA SDK and LZMA Utils. The core of the new LZMA Utils was liblzma, a compression library with a zlib-like API. liblzma supported both the old and new file format. The gzip-like lzma command-line tool was rewritten to use liblzma. The new LZMA Utils code base was renamed to XZ Utils when the name of the new file format had been decided. The liblzma compression library retained its name though, because changing it would have caused unnecessary breakage in applications already using the early liblzma snapshots. The xz command-line tool can emulate the gzip-like lzma tool by creating appropriate symlinks (e.g. lzma -> xz). Thus, practically all scripts using the lzma tool from LZMA Utils will work as is with XZ Utils (and will keep using the old .lzma format). Still, the .lzma format is more or less deprecated. XZ Utils will keep supporting it, but new applications should use the .xz format, and migrating old applications to .xz is often a good idea too. xz-5.1.3alpha/doc/faq.txt0000644000000000000000000002230112232714400012124 00000000000000 XZ Utils FAQ ============ Q: What do the letters XZ mean? A: Nothing. They are just two letters, which come from the file format suffix .xz. The .xz suffix was selected, because it seemed to be pretty much unused. It has no deeper meaning. Q: What are LZMA and LZMA2? A: LZMA stands for Lempel-Ziv-Markov chain-Algorithm. It is the name of the compression algorithm designed by Igor Pavlov for 7-Zip. LZMA is based on LZ77 and range encoding. LZMA2 is an updated version of the original LZMA to fix a couple of practical issues. In context of XZ Utils, LZMA is called LZMA1 to emphasize that LZMA is not the same thing as LZMA2. LZMA2 is the primary compression algorithm in the .xz file format. Q: There are many LZMA related projects. How does XZ Utils relate to them? A: 7-Zip and LZMA SDK are the original projects. LZMA SDK is roughly a subset of the 7-Zip source tree. p7zip is 7-Zip's command-line tools ported to POSIX-like systems. LZMA Utils provide a gzip-like lzma tool for POSIX-like systems. LZMA Utils are based on LZMA SDK. XZ Utils are the successor to LZMA Utils. There are several other projects using LZMA. Most are more or less based on LZMA SDK. See . Q: Why is liblzma named liblzma if its primary file format is .xz? Shouldn't it be e.g. libxz? A: When the designing of the .xz format began, the idea was to replace the .lzma format and use the same .lzma suffix. It would have been quite OK to reuse the suffix when there were very few .lzma files around. However, the old .lzma format became popular before the new format was finished. The new format was renamed to .xz but the name of liblzma wasn't changed. Q: Do XZ Utils support the .7z format? A: No. Use 7-Zip (Windows) or p7zip (POSIX-like systems) to handle .7z files. Q: I have many .tar.7z files. Can I convert them to .tar.xz without spending hours recompressing the data? A: In the "extra" directory, there is a script named 7z2lzma.bash which is able to convert some .7z files to the .lzma format (not .xz). It needs the 7za (or 7z) command from p7zip. The script may silently produce corrupt output if certain assumptions are not met, so decompress the resulting .lzma file and compare it against the original before deleting the original file! Q: I have many .lzma files. Can I quickly convert them to the .xz format? A: For now, no. Since XZ Utils supports the .lzma format, it's usually not too bad to keep the old files in the old format. If you want to do the conversion anyway, you need to decompress the .lzma files and then recompress to the .xz format. Technically, there is a way to make the conversion relatively fast (roughly twice the time that normal decompression takes). Writing such a tool would take quite a bit of time though, and would probably be useful to only a few people. If you really want such a conversion tool, contact Lasse Collin and offer some money. Q: I have installed xz, but my tar doesn't recognize .tar.xz files. How can I extract .tar.xz files? A: xz -dc foo.tar.xz | tar xf - Q: Can I recover parts of a broken .xz file (e.g. a corrupted CD-R)? A: It may be possible if the file consists of multiple blocks, which typically is not the case if the file was created in single-threaded mode. There is no recovery program yet. Q: Is (some part of) XZ Utils patented? A: Lasse Collin is not aware of any patents that could affect XZ Utils. However, due to the nature of software patents, it's not possible to guarantee that XZ Utils isn't affected by any third party patent(s). Q: Where can I find documentation about the file format and algorithms? A: The .xz format is documented in xz-file-format.txt. It is a container format only, and doesn't include descriptions of any non-trivial filters. Documenting LZMA and LZMA2 is planned, but for now, there is no other documentation than the source code. Before you begin, you should know the basics of LZ77 and range-coding algorithms. LZMA is based on LZ77, but LZMA is a lot more complex. Range coding is used to compress the final bitstream like Huffman coding is used in Deflate. Q: I cannot find BCJ and BCJ2 filters. Don't they exist in liblzma? A: BCJ filter is called "x86" in liblzma. BCJ2 is not included, because it requires using more than one encoded output stream. A streamable version of BCJ2-style filtering is planned. Q: I need to use a script that runs "xz -9". On a system with 256 MiB of RAM, xz says that it cannot allocate memory. Can I make the script work without modifying it? A: Set a default memory usage limit for compression. You can do it e.g. in a shell initialization script such as ~/.bashrc or /etc/profile: XZ_DEFAULTS=--memlimit-compress=150MiB export XZ_DEFAULTS xz will then scale the compression settings down so that the given memory usage limit is not reached. This way xz shouldn't run out of memory. Check also that memory-related resource limits are high enough. On most systems, "ulimit -a" will show the current resource limits. Q: How do I create files that can be decompressed with XZ Embedded? A: See the documentation in XZ Embedded. In short, something like this is a good start: xz --check=crc32 --lzma2=preset=6e,dict=64KiB Or if a BCJ filter is needed too, e.g. if compressing a kernel image for PowerPC: xz --check=crc32 --powerpc --lzma2=preset=6e,dict=64KiB Adjust the dictionary size to get a good compromise between compression ratio and decompressor memory usage. Note that in single-call decompression mode of XZ Embedded, a big dictionary doesn't increase memory usage. Q: Will xz support threaded compression? A: It is planned and has been taken into account when designing the .xz file format. Eventually there will probably be three types of threading, each method having its own advantages and disadvantages. The simplest method is splitting the uncompressed data into blocks and compressing them in parallel independent from each other. Since the blocks are compressed independently, they can also be decompressed independently. Together with the index feature in .xz, this allows using threads to create .xz files for random-access reading. This also makes threaded decompression possible, although it is not clear if threaded decompression will ever be implemented. The independent blocks method has a couple of disadvantages too. It will compress worse than a single-block method. Often the difference is not too big (maybe 1-2 %) but sometimes it can be too big. Also, the memory usage of the compressor increases linearly when adding threads. Match finder parallelization is another threading method. It has been in 7-Zip for ages. It doesn't affect compression ratio or memory usage significantly. Among the three threading methods, only this is useful when compressing small files (files that are not significantly bigger than the dictionary). Unfortunately this method scales only to about two CPU cores. The third method is pigz-style threading (I use that name, because pigz uses that method). It doesn't affect compression ratio significantly and scales to many cores. The memory usage scales linearly when threads are added. This isn't significant with pigz, because Deflate uses only a 32 KiB dictionary, but with LZMA2 the memory usage will increase dramatically just like with the independent-blocks method. There is also a constant computational overhead, which may make pigz-method a bit dull on dual-core compared to the parallel match finder method, but with more cores the overhead is not a big deal anymore. Combining the threading methods will be possible and also useful. E.g. combining match finder parallelization with pigz-style threading can cut the memory usage by 50 %. It is possible that the single-threaded method will be modified to create files identical to the pigz-style method. We'll see once pigz-style threading has been implemented in liblzma. Q: How do I build a program that needs liblzmadec (lzmadec.h)? A: liblzmadec is part of LZMA Utils. XZ Utils has liblzma, but no liblzmadec. The code using liblzmadec should be ported to use liblzma instead. If you cannot or don't want to do that, download LZMA Utils from . Q: The default build of liblzma is too big. How can I make it smaller? A: Give --enable-small to the configure script. Use also appropriate --enable or --disable options to include only those filter encoders and decoders and integrity checks that you actually need. Use CFLAGS=-Os (with GCC) or equivalent to tell your compiler to optimize for size. See INSTALL for information about configure options. If the result is still too big, take a look at XZ Embedded. It is a separate project, which provides a limited but significantly smaller XZ decoder implementation than XZ Utils.

On POSIX systems, the examples should build by just typing "make". The examples that use stdin or stdout don't set stdin and stdout to binary mode. On systems where it matters (e.g. Windows) it is possible that the examples won't work without modification.
