Changelog for xz-5.4.3-4.166.x86_64.rpm :

* Fri May 05 2023 andreas.stiegerAATTgmx.de- Update to version 5.4.3:
* Build system fixes
* Translation updates: Croatian- update signing key
* Thu Apr 06 2023 fcrozatAATTsuse.com- Update license tag, there is GPL-3.0-or-later code too.
* Mon Mar 20 2023 mpluskalAATTsuse.com- Update to version 5.4.2:
* All fixes from 5.2.11 that were not included in 5.4.1.
* If xz is built with support for the Capsicum sandbox but running in an environment that doesn\'t support Capsicum, xz now runs normally without sandboxing instead of exiting with an error.
* liblzma: - Documentation was updated to improve the style, consistency, and completeness of the liblzma API headers. - The Doxygen-generated HTML documentation for the liblzma API header files is now included in the source release and is installed as part of \"make install\". All JavaScript is removed to simplify license compliance and to reduce the install size. - Fixed a minor bug in lzma_str_from_filters() that produced too many filters in the output string instead of reporting an error if the input array had more than four filters. This bug did not affect xz.
* Build systems: - autogen.sh now invokes the doxygen tool via the new wrapper script doxygen/update-doxygen, unless the command line option - -no-doxygen is used. - Added microlzma_encoder.c and microlzma_decoder.c to the VS project files for Windows and to the CMake build. These should have been included in 5.3.2alpha.
* Tests: - Added a test to the CMake build that was forgotten in the previous release. - Added and refactored a few tests.
* Translations: - Updated the Brazilian Portuguese translation. - Added Brazilian Portuguese man page translation.
* Wed Mar 08 2023 mpluskalAATTsuse.com- Build AVX2 enabled hwcaps library for x86_64-v3
* Sat Jan 21 2023 dmuellerAATTsuse.com- update to 5.4.1:
* liblzma: - Fixed the return value of lzma_microlzma_encoder() if the LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options made the function return LZMA_STREAM_END without encoding anything instead of returning LZMA_OPTIONS_ERROR.
* Tests: - Fixed test script compatibility with ancient /bin/sh versions. Now the five test_compress_
* tests should no longer fail on Solaris 10. - Added and refactored a few tests.
* Translations: - Updated the Catalan and Esperanto translations. - Added Korean and Ukrainian man page translations.
* Fri Dec 30 2022 dmuellerAATTsuse.com- update to 5.4.0: This bumps the minor version of liblzma because new features were added. The API and ABI are still backward compatible with liblzma 5.2.x and 5.0.x. Summary of new features added in the 5.3.x development releases:
* liblzma: - Added threaded .xz decompressor lzma_stream_decoder_mt(). It can use multiple threads with .xz files that have multiple Blocks with size information in Block Headers. The threaded encoder in xz has always created such files. Single-threaded encoder cannot store the size information in Block Headers even if one used LZMA_FULL_FLUSH to create multiple Blocks, so this threaded decoder cannot use multiple threads with such files. If there are multiple Streams (concatenated .xz files), one Stream will be decompressed completely before starting the next Stream. - A new decoder flag LZMA_FAIL_FAST was added. It makes the threaded decompressor report errors soon instead of first flushing all pending data before the error location. - New Filter IDs:
* LZMA_FILTER_ARM64 is for ARM64 binaries.
* LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don\'t necessarily use the end marker. - Added lzma_str_to_filters(), lzma_str_from_filters(), and lzma_str_list_filters() to convert a preset or a filter chain string to a lzma_filter[] and vice versa. These should make it easier to write applications that allow users to specify custom compression options. - Added lzma_filters_free() which can be convenient for freeing the filter options in a filter chain (an array of lzma_filter structures). - lzma_file_info_decoder() to makes it a little easier to get the Index field from .xz files. This helps in getting the uncompressed file size but an easy-to-use random access API is still missing which has existed in XZ for Java for a long time. - Added lzma_microlzma_encoder() and lzma_microlzma_decoder(). It is used by erofs-utils and may be used by others too. The MicroLZMA format is a raw LZMA stream (without end marker) whose first byte (always 0x00) has been replaced with bitwise-negation of the LZMA properties (lc/lp/pb). It was created for use in EROFS but may be used in other contexts as well where it is important to avoid wasting bytes for stream headers or footers. The format is also supported by XZ Embedded (the XZ Embedded version in Linux got MicroLZMA support in Linux 5.16). The MicroLZMA encoder API in liblzma can compress into a fixed-sized output buffer so that as much data is compressed as can be fit into the buffer while still creating a valid MicroLZMA stream. This is needed for EROFS. - Added lzma_lzip_decoder() to decompress the .lz (lzip) file format version 0 and the original unextended version 1 files. Also lzma_auto_decoder() supports .lz files. - lzma_filters_update() can now be used with the multi-threaded encoder (lzma_stream_encoder_mt()) to change the filter chain after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH. - In lzma_options_lzma, allow nice_len = 2 and 3 with the match finders that require at least 3 or 4. Now it is internally rounded up if needed. - CLMUL-based CRC64 on x86-64 and E2K with runtime processor detection. On 32-bit x86 it currently isn\'t available unless - -disable-assembler is used which can make the non-CLMUL CRC64 slower; this might be fixed in the future. - Building with --disable-threads --enable-small is now thread-safe if the compiler supports __attribute__((__constructor__)).
* xz: - Using -T0 (--threads=0) will now use multi-threaded encoder even on a single-core system. This is to ensure that output from the same xz binary is identical on both single-core and multi-core systems. - --threads=+1 or -T+1 is now a way to put xz into multi-threaded mode while using only one worker thread. The + is ignored if the number is not 1. - A default soft memory usage limit is now used for compression when -T0 is used and no explicit limit has been specified. This soft limit is used to restrict the number of threads but if the limit is exceeded with even one thread then xz will continue with one thread using the multi-threaded encoder and this limit is ignored. If the number of threads is specified manually then no default limit will be used; this affects only -T0. This change helps on systems that have very many cores and using all of them for xz makes no sense. Previously xz -T0 could run out of memory on such systems because it attempted to reserve memory for too many threads. This also helps with 32-bit builds which don\'t have a large amount of address space that would be required for many threads. The default soft limit for -T0 is at most 1400 MiB on all 32-bit platforms. - Previously a low value in --memlimit-compress wouldn\'t cause xz to switch from multi-threaded mode to single-threaded mode if the limit cannot otherwise be met; xz failed instead. Now xz can switch to single-threaded mode and then, if needed, scale down the LZMA2 dictionary size too just like it already did when it was started in single-threaded mode. - The option --no-adjust no longer prevents xz from scaling down the number of threads as that doesn\'t affect the compressed output (only performance). Now --no-adjust only prevents adjustments that affect compressed output, that is, with - -no-adjust xz won\'t switch from multi-threaded mode to single-threaded mode and won\'t scale down the LZMA2 dictionary size. - Added a new option --memlimit-mt-decompress=LIMIT. This is used to limit the number of decompressor threads (possibly falling back to single-threaded mode) but it will never make xz refuse to decompress a file. This has a system-specific default value because without any limit xz could end up allocating memory for the whole compressed input file, the whole uncompressed output file, multiple thread-specific decompressor instances and so on. Basically xz could attempt to use an insane amount of memory even with fairly common files. The system-specific default value is currently the same as the one used for compression with -T0. The new option works together with the existing option - -memlimit-decompress=LIMIT. The old option sets a hard limit that must not be exceeded (xz will refuse to decompress) while the new option only restricts the number of threads. If the limit set with --memlimit-mt-decompress is greater than the limit set with --memlimit-compress, then the latter value is used also for --memlimit-mt-decompress. - Added new information to the output of xz --info-memory and new fields to the output of xz --robot --info-memory. - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders now that liblzma handles it. - Don\'t mention endianness for ARM and ARM-Thumb filters in - -long-help. The filters only work for little endian instruction encoding but modern ARM processors using big endian data access still use little endian instruction encoding. So the help text was misleading. In contrast, the PowerPC filter is only for big endian 32/64-bit PowerPC code. Little endian PowerPC would need a separate filter. - Added decompression support for the .lz (lzip) file format version 0 and the original unextended version 1. It is autodetected by default. See also the option --format on the xz man page. - Sandboxing enabled by default:
* Capsicum (FreeBSD)
* pledge(2) (OpenBSD)
* Scripts now support the .lz format using xz.
* A few new tests were added.
* The liblzma-specific tests are now supported in CMake-based builds too (\"make test\").
* Sat Dec 17 2022 dmuellerAATTsuse.com- update to 5.2.10:
* xz: Don\'t modify argv[] when parsing the --memlimit
* and - -block-list command line options. This fixes confusing arguments in process listing (like \"ps auxf\").
* GNU/Linux only: Use __has_attribute(__symver__) to detect if that attribute is supported. This fixes build on Mandriva where Clang is patched to define __GNUC__ to 11 by default (instead of 4 as used by Clang upstream).
* liblzma: - Fixed an infinite loop in LZMA encoder initialization if dict_size >= 2 GiB. - Fixed two cases of invalid free() that can happen if a tiny allocation fails in encoder re-initialization or in lzma_filters_update(). These bugs had some similarities with the bug fixed in 5.2.7. - Fixed lzma_block_encoder() not allowing the use of LZMA_SYNC_FLUSH with lzma_code() even though it was documented to be supported. The sync-flush code in the Block encoder was already used internally via lzma_stream_encoder(), so this was just a missing flag in the lzma_block_encoder() API function. - GNU/Linux only: Don\'t put symbol versions into static liblzma as it breaks things in some cases (and even if it didn\'t break anything, symbol versions in static libraries are useless anyway). The downside of the fix is that if the configure options --with-pic or --without-pic are used then it\'s not possible to build both shared and static liblzma at the same time on GNU/Linux anymore; with those options --disable-static or --disable-shared must be used too.- drop unused xz-devel-static which is no longer supported when using - -with-pic (which is needed for shared libs)
* Thu Dec 01 2022 jengelhAATTinai.de- Rename xz-static-devel -> xz-devel-static to follow the general naming used in openSUSE.
* Fri Nov 18 2022 danilo.spinellaAATTsuse.com- Update to 5.2.8:
* xz: - If xz cannot remove an input file when it should, this is now treated as a warning (exit status 2) instead of an error (exit status 1). This matches GNU gzip and it is more logical as at that point the output file has already been successfully closed. - Fix handling of .xz files with an unsupported check type. Previously such printed a warning message but then xz behaved as if an error had occurred (didn\'t decompress, exit status 1). Now a warning is printed, decompression is done anyway, and exit status is 2. This used to work slightly before 5.0.0. In practice this bug matters only if xz has been built with some check types disabled. As instructed in PACKAGERS, such builds should be done in special situations only. - Fix \"xz -dc --single-stream tests/files/good-0-empty.xz\" which failed with \"Internal error (bug)\". That is, - -single-stream was broken if the first .xz stream in the input file didn\'t contain any uncompressed data. - Fix displaying file sizes in the progress indicator when working in passthru mode and there are multiple input files. Just like \"gzip -cdf\", \"xz -cdf\" works like \"cat\" when the input file isn\'t a supported compressed file format. In this case the file size counters weren\'t reset between files so with multiple input files the progress indicator displayed an incorrect (too large) value.
* liblzma: - API docs in lzma/container.h:
* Update the list of decoder flags in the decoder function docs.
* Explain LZMA_CONCATENATED behavior with .lzma files in lzma_auto_decoder() docs. - OpenBSD: Use HW_NCPUONLINE to detect the number of available hardware threads in lzma_physmem(). - Fix use of wrong macro to detect x86 SSE2 support. __SSE2_MATH__ was used with GCC/Clang but the correct one is __SSE2__. The first one means that SSE2 is used for floating point math which is irrelevant here. The affected SSE2 code isn\'t used on x86-64 so this affects only 32-bit x86 builds that use -msse2 without -mfpmath=sse (there is no runtime detection for SSE2). It improves LZMA compression speed (not decompression). - Fix the build with Intel C compiler 2021 (ICC, not ICX) on Linux. It defines __GNUC__ to 10 but doesn\'t support the __symver__ attribute introduced in GCC 10.
* Scripts: Ignore warnings from xz by using --quiet --no-warn. This is needed if the input .xz files use an unsupported check type.
* Translations: - Updated Croatian and Turkish translations. - One new translations wasn\'t included because it needed technical fixes. It will be in upcoming 5.4.0. No new translations will be added to the 5.2.x branch anymore. - Renamed the French man page translation file from fr_FR.po to fr.po and thus also its install directory (like /usr/share/man/fr_FR -> .../fr). - Man page translations for upcoming 5.4.0 are now handled in the Translation Project.
* Update doc/faq.txt a little so it\'s less out-of-date.
* Tue Oct 04 2022 gmbr3AATTopensuse.org- Move localised man pages to lang subpackage
* Fri Sep 30 2022 c.jAATTtuta.io- update to 5.2.7:
* liblzma: - Add API doc note about the .xz decoder LZMA_MEMLIMIT_ERROR bug. - Add dest and src NULL checks to lzma_index_cat. The documentation states LZMA_PROG_ERROR can be returned from lzma_index_cat. Previously, lzma_index_cat could not return LZMA_PROG_ERROR. Now, the validation is similar to lzma_index_append, which does a NULL check on the index parameter. - Fix copying of check type statistics in lzma_index_cat(). The check type of the last Stream in dest was never copied to dest->checks (the code tried to copy it but it was done too late). This meant that the value returned by lzma_index_checks() would only include the check type of the last Stream when multiple lzma_indexes had been concatenated. In xz --list this meant that the summary would only list the check type of the last Stream, so in this sense this was only a visual bug. However, it\'s possible that some applications use this information for purposes other than merely showing it to the users in an informational message. I\'m not aware of such applications though and it\'s quite possible that such applications don\'t exist. Regular streamed decompression in xz or any other application doesn\'t use lzma_index_cat() and so this bug cannot affect them. - Stream decoder: Fix restarting after LZMA_MEMLIMIT_ERROR. If lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible to use lzma_memlimit_set() to increase the limit and continue decoding. This was supposed to work from the beginning but there was a bug. With other decoders (.lzma or threaded .xz) this already worked correctly. - lzma_filters_copy: Keep dest[] unmodified if an error occurs. lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed this. Before this patch, failing lzma_filters_copy() could result in free(invalid_pointer) or invalid memory reads in stream_encoder.c or stream_encoder_mt.c. To trigger this, allocating memory for a filter options structure has to fail. These are tiny allocations so in practice they very rarely fail. Certain badness in the filter chain array could also make lzma_filters_copy() fail but both stream_encoder.c and stream_encoder_mt.c validate the filter chain before trying to copy it, so the crash cannot occur this way. - lzma_index_append: Add missing integer overflow check. The documentation in src/liblzma/api/lzma/index.h suggests that both the unpadded (compressed) size and the uncompressed size are checked for overflow, but only the unpadded size was checked. The uncompressed check is done first since that is more likely to occur than the unpadded or index field size overflows. - Vaccinate against an ill patch from RHEL/CentOS 7.
* xzgrep: - Fix compatibility with old shells. Turns out that some old shells don\'t like apostrophes (\') inside command substitutions. The problem was introduced by commits 69d1b3fc29677af8ade8dc15dba83f0589cb63d6 (2022-03-29), bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and a648978b20495b7aa4a8b029c5a810b5ad9d08ff (2022-07-19). 5.2.6 is the only stable release that included this problem.
* Translations: Add Turkish translation.
* Fri Aug 12 2022 dmuellerAATTsuse.com- update to 5.2.6 (CVE-2022-1271, bsc#1198062):
* xz: - The --keep option now accepts symlinks, hardlinks, and setuid, setgid, and sticky files. - When copying metadata from the source file to the destination file, don\'t try to set the group (GID) if it is already set correctly. This avoids a failure on OpenBSD (and possibly on a few other OSes) where files may get created so that their group doesn\'t belong to the user, and fchown(2) can fail even if it needs to do nothing. - Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on MIPS32 because on MIPS32 userspace processes are limited to 2 GiB of address space.
* liblzma: - Fixed a missing error-check in the threaded encoder. If a small memory allocation fails, a .xz file with an invalid Index field would be created. Decompressing such a file would produce the correct output but result in an error at the end. Thus this is a \"mild\" data corruption bug. Note that while a failed memory allocation can trigger the bug, it cannot cause invalid memory access. - The decoder for .lzma files now supports files that have uncompressed size stored in the header and still use the end of payload marker (end of stream marker) at the end of the LZMA stream. Such files are rare but, according to the documentation in LZMA SDK, they are valid. doc/lzma-file-format.txt was updated too. - Improved 32-bit x86 assembly files:
* Support Intel Control-flow Enforcement Technology (CET)
* Use non-executable stack on FreeBSD.
* xzgrep: - Fixed arbitrary command injection via a malicious filename (CVE-2022-1271, ZDI-CAN-16587). A standalone patch for this was released to the public on 2022-04-07. A slight robustness improvement has been made since then and, if using GNU or
*BSD grep, a new faster method is now used that doesn\'t use the old sed-based construct at all. This also fixes bad output with GNU grep >= 3.5 (2020-09-27) when xzgrepping binary files. - Fixed detection of corrupt .bz2 files. - Improved error handling to fix exit status in some situations and to fix handling of signals: in some situations a signal didn\'t make xzgrep exit when it clearly should have. It\'s possible that the signal handling still isn\'t quite perfect but hopefully it\'s good enough. - Documented exit statuses on the man page. - xzegrep and xzfgrep now use \"grep -E\" and \"grep -F\" instead of the deprecated egrep and fgrep commands. - Fixed parsing of the options -E, -F, -G, -P, and -X. The problem occurred when multiple options were specied in a single argument, for example, echo foo | xzgrep -Fe foo treated foo as a filename because -Fe wasn\'t correctly split into -F -e. - Added zstd support.
* xzdiff/xzcmp: - Fixed wrong exit status. Exit status could be 2 when the correct value is 1. - Documented on the man page that exit status of 2 is used for decompression errors. - Added zstd support.
* xzless: - Fix less(1) version detection. It failed if the version number from \"less -V\" contained a dot.
* Tue Apr 12 2022 meissnerAATTsuse.com- use https urls.
* Mon Jun 07 2021 jengelhAATTinai.de- Upgrade old rpm constructs.
* Wed Mar 18 2020 infoAATTpaolostivanin.com- Update to 5.2.5:
* liblzma: - Fixed several C99/C11 conformance bugs. Now the code is clean under gcc/clang -fsanitize=undefined. Some of these changes might have a negative effect on performance with old GCC versions or compilers other than GCC and Clang. The configure option --enable-unsafe-type-punning can be used to (mostly) restore the old behavior but it shouldn\'t normally be used. - Improved API documentation of lzma_properties_decode(). - Added a very minor encoder speed optimization.
* xz: - Fixed a crash in \"xz -dcfv not_an_xz_file\". All four options were required to trigger it. The crash occurred in the progress indicator code when xz was in passthru mode where xz works like \"cat\". - Fixed an integer overflow with 32-bit off_t. It could happen when decompressing a file that has a long run of zero bytes which xz would try to write as a sparse file. Since the build system enables large file support by default, off_t is normally 64-bit even on 32-bit systems. - Fixes for --flush-timeout:
* Fix semi-busy-waiting.
* Avoid unneeded flushes when no new input has arrived since the previous flush was completed. - Added a special case for 32-bit xz: If --memlimit-compress is used to specify a limit that exceeds 4020 MiB, the limit will be set to 4020 MiB. The values \"0\" and \"max\" aren\'t affected by this and neither is decompression. This hack can be helpful when a 32-bit xz has access to 4 GiB address space but the specified memlimit exceeds 4 GiB. This can happen e.g. with some scripts. - Capsicum sandbox is now enabled by default where available (FreeBSD >= 10). The sandbox debug messages (xz -vv) were removed since they seemed to be more annoying than useful.
* Thu Sep 19 2019 lnusselAATTsuse.de- Do not recommend lang package. The lang package already has a supplements.
* Fri Aug 02 2019 mliskaAATTsuse.cz- Use FAT LTO objects in order to provide proper static library.
* Tue May 21 2019 kstreitovaAATTsuse.com- add SUSE-Public-Domain licence as some parts of xz utils (liblzma, xz, xzdec, lzmadec, documentation, translated messages, tests, debug, extra directory) are in public domain licence [bsc#1135709]
* Fri Jun 15 2018 astiegerAATTsuse.com- xz 5.2.4:
* liblzma: - Allow 0 as memory usage limit instead of returning LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified, which effectively is the same as 0. - Use \"noexcept\" keyword instead of \"throw()\" in the public headers when a C++11 (or newer standard) compiler is used. - Added a portability fix for recent Intel C Compilers.
* xz: - Fix \"xz --list --robot missing_or_bad_file.xz\" which would try to print an unitialized string and thus produce garbage output. Since the exit status is non-zero, most uses of such a command won\'t try to interpret the garbage output. - \"xz --list foo.xz\" could print \"Internal error (bug)\" in a corner case where a specific memory usage limit had been set.
* Mon Mar 19 2018 kukukAATTsuse.de- Use %license instead of %doc [bsc#1082318]

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
* Sun Jul 29 2012 jengelhAATTinai.de- Disable profiling on SPARC due to compiler bug [gcc #54121]
* Fri Jul 06 2012 sweet_f_aAATTgmx.de- correct license \"LGPL-2.1+ and GPL-2.0+\" (bnc#770195)
* Sun Feb 12 2012 crrodriguezAATTopensuse.org- Put libraries back in %{_libdir}, /usr merge project.

* Fri Sep 30 2011 crrodriguezAATTopensuse.org- Fix build in armv5el doesnt like profiling
* Tue Sep 27 2011 sweet_f_aAATTgmx.de- minor fixes of last portability changes:

* don\'t define do_factory, just use lang_package instead
* simplify files section
* do_profiling for some more systems
* Mon Sep 26 2011 cooloAATTsuse.com- build on SLE_10
* Sat Sep 17 2011 cooloAATTsuse.com- remove _service, too fragile
* Fri Sep 16 2011 jengelhAATTmedozas.de- Add xz-devel to baselibs- Remove redundant sections
* Tue Jun 14 2011 dmuellerAATTsuse.de- add recommends xz-lang
* Wed Jun 08 2011 cooloAATTnovell.com- Update to version 5.0.3
* 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.
* Thu Apr 07 2011 crrodriguezAATTopensuse.org- Update to version 5.0.2
* 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.
* Fri Mar 04 2011 crrodriguezAATTopensuse.org- Update to version 5.0.1
* Fix --force on setuid/setgid/sticky and multi-hardlink files.
* Add alloc_size and malloc attributes to a few functions.

* The memory usage limit is now disabled by default
* Added support for XZ_DEFAULTS environment variable
* The compression settings associated with the preset levels have been changed,they are now less likely to make compression worse.
* Support for \"xz --list\" was added
* Sat Apr 24 2010 cooloAATTnovell.com- buildrequire pkg-config to fix provides

* fix data corruption in LZ/LZMA2 encoder.
* major documentation update
* install lzdiff, lzgrep, and lzmore as symlinks
* make the default memory usage limit 40 % of RAM for both compressing and decompressing.
* fixed a crash in liblzma See git://ctrl.tukaani.org/xz.git for more
* Sun Jun 07 2009 crrodriguezAATTsuse.de- remove static libraries, see bnc#509945 for details
* Sun Feb 22 2009 roAATTsuse.de- added baselibs.conf (for rpm-32bit)
* Mon Feb 16 2009 cooloAATTsuse.de- use bzip payload, so users are able to install new rpm on old systems

* Fri Feb 06 2009 schwabAATTsuse.de- Update to xz-4.999.8beta. See git://ctrl.tukaani.org/lzma-utils.git.
* Wed Jan 07 2009 schwabAATTsuse.de- Update to xz-4.999.7beta. See git://ctrl.tukaani.org/lzma-utils.git.- Rename to xz.
* Wed Jul 30 2008 schwabAATTsuse.de- Update to lzma-4.32.7.
* If \"lzma -t\" is run on a corrupt file or interrupted by a signal, don\'t unlink /dev/null.
* Partial fix to race conditions where a signal could make lzma to unlink both the source and destination files. Now it cannot lose data anymore, but with bad luck an incomplete file may be left on the disk.
* Wed May 14 2008 schwabAATTsuse.de- Update to lzma-4.32.6.
* Always use 32-bit integer to hold probability variables. Earlier, these were 64-bit on 64-bit architectures, which hurt cache efficiency in the CPU, and thus performance of LZMA. 32-bit architectures are not affected by this change.
* Fix a theoretical data corruption bug in the LZMA encoder. It is about overflowing a 32-bit integer, whose typical value stays below five. I don\'t know if it is actually possible to construct to a file that could make it overflow. Even if it were possible, it would \"only\" make the output file corrupt so that it is 4 GiB too small; there are no other security risks. Now the integer is 64-bit to be sure it won\'t overflow.
* Add support for copying timestamps on operating systems that support setting timestamps only by filename, not by file descriptor.
* Several portability fixes were made.
* Fri May 09 2008 schwabAATTsuse.de- Revert last changes.
* Tue May 06 2008 bkAATTsuse.de- ci removed #neededforbuild while mbuild converts to BuildRequires- bzip2 source to save space (not lzma, so it can be built in <11.0)
* Tue May 06 2008 bkAATTsuse.de- run the package-provided self-test by adding a call to \'make check\'- use %configure instead of equivalent configure call with options- improved to allow building in SLES and non-SUSE repositories, eg: - replace obsolete nostatic patch with check for static objects - use more generic wildcards in the file list for manual pages
* Mon Feb 04 2008 schwabAATTsuse.de- Fix installation.
* Mon Feb 04 2008 schwabAATTsuse.de- Update to lzma-4.32.5.
* The percentage shown when --verbose is used, works again. Also some typos were fixed from the messages printed by --verbose.
* Several small portability fixes were made.
* Fri Jan 04 2008 crrodriguezAATTsuse.de- Version 4.32.4
* Ignore command line switch --format=alone. This way current scripts can be written so that they will produce LZMA_Alone format files even with the new command line tool once it is finishes along with liblzma.
* The command line tool now tells if the user tries to decode files in the new .lzma format. The message recommends upgrading to newer LZMA Utils.
* Added some internal consistency checks to liblzmadec, so that it doesn\'t crash if given lzmadec_stream whose initialization failed. Some applications using zlib and libbzip2 don\'t check if initialization was successful, and expect that error gets caught safely later.- disable static libraries- remove liblzmadec.la that has empty dependency_libs- do not link utils statically
* Mon Dec 03 2007 dmuellerAATTsuse.de- update to 4.32.3:
* rare file content loss bugs fixed (did not check for error upon close())
* permissions copying fixed- testsuited switched partially to GPLv3- fix library package name
* Thu Oct 11 2007 schwabAATTsuse.de- Fix missing include.
* Wed Oct 10 2007 schwabAATTsuse.de- Initial version 4.32.0beta5.
