- 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 17:23:35 UTC 2022 - Dirk Müller <dmueller@suse.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  1 09:33:47 UTC 2022 - Jan Engelhardt <jengelh@inai.de>

- Rename xz-static-devel -> xz-devel-static to follow the general
  naming used in openSUSE.

-------------------------------------------------------------------
Fri Nov 18 10:56:35 UTC 2022 - Danilo Spinella <danilo.spinella@suse.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  4 20:36:09 UTC 2022 - Callum Farmer <gmbr3@opensuse.org>

- Move localised man pages to lang subpackage

-------------------------------------------------------------------
Fri Sep 30 21:20:14 UTC 2022 - C J <c.j@tuta.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 20:50:23 UTC 2022 - Dirk Müller <dmueller@suse.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.

-------------------------------------------------------------------
Wed Mar 18 11:11:48 UTC 2020 - Paolo Stivanin <info@paolostivanin.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.

  debug, extra directory) are in public domain licence [bsc#1135709]

-------------------------------------------------------------------
Fri Jun 15 11:11:38 UTC 2018 - astieger@suse.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.

Thu Dec 25 20:23:28 UTC 2014 - andreas.stieger@gmx.de

- xz 5.2.0:
  * liblzma:
    - Added support for multi-threaded compression
    - 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 LZMA_IGNORE_CHECK.
    - A few speed optimizations were made.
    - Added support for symbol versioning. It is enabled by default
      on GNU/Linux, other GNU-based systems, and FreeBSD.
  * xz:
    - Fixed a race condition in the signal handling
    - Multi-threaded decompression can be enabled with the
      --threads (-T) option.
    - New command line options in xz: --single-stream,
      --block-size=SIZE, --block-list=SIZES,
      --flush-timeout=TIMEOUT, and --ignore-check.
    - 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.
  * xzdiff and xzgrep now support .lzo files if lzop is installed.
    The .tzo suffix is also recognized as a shorthand for .tar.lzo.

  * Fix regressions introduced in 5.0.6:
    - Fix building with non-GNU make.
    - Fix invalid Libs.private value in liblzma.pc which broke
      static linking against liblzma if the linker flags were
      taken from pkg-config.

- Update to version 5.0.4
  * 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.

Wed Jun  8 19:25:51 UTC 2011 - coolo@novell.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  7 20:43:05 UTC 2011 - crrodriguez@opensuse.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  4 17:54:21 UTC 2011 - crrodriguez@opensuse.org

- Update to version 5.0.1
*  Fix --force on setuid/setgid/sticky and multi-hardlink files.

- Rename to xz.

-------------------------------------------------------------------
Wed Jul 30 13:53:18 CEST 2008 - schwab@suse.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 22:04:25 CEST 2008 - schwab@suse.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  9 11:51:42 CEST 2008 - schwab@suse.de

  * Several small portability fixes were made.

-------------------------------------------------------------------
Fri Jan  4 07:12:26 CET 2008 - crrodriguez@suse.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  3 14:12:12 CET 2007 - dmueller@suse.de
