xz: update to 5.6.0.

5.6.0 (2024-02-24)

    This bumps the minor version of liblzma because new features were
    added. The API and ABI are still backward compatible with liblzma
    5.4.x and 5.2.x and 5.0.x.

    NOTE: As described in the NEWS for 5.5.2beta, the core components
    are now under the BSD Zero Clause License (0BSD).

    Since 5.5.2beta:

    * liblzma:

        - Disabled the branchless C variant in the LZMA decoder based
          on the benchmark results from the community.

        - Disabled x86-64 inline assembly on x32 to fix the build.

    * Sandboxing support in xz:

        - Landlock is now used even when xz needs to create files.
          In this case the sandbox is has to be more permissive than
          when no files need to be created. A similar thing was
          already in use with pledge(2) since 5.3.4alpha.

        - Landlock and pledge(2) are now stricter when reading from
          more than one input file and only writing to standard output.

        - Added support for Landlock ABI version 4.

    * CMake:

        - Default to -O2 instead of -O3 with CMAKE_BUILD_TYPE=Release.
          -O3 is not useful for speed and makes the code larger.

        - Now builds lzmainfo and lzmadec.

        - xzdiff, xzgrep, xzless, xzmore, and their symlinks are now
          installed. The scripts are also tested during "make test".

        - Added translation support for xz, lzmainfo, and the
          man pages.

        - Applied the symbol versioning workaround for MicroBlaze that
          is used in the Autotools build.

        - The general XZ Utils and liblzma API documentation is now
          installed.

        - The CMake component names were changed a little and several
          were added. liblzma_Runtime and liblzma_Development are
          unchanged.

        - Minimum required CMake version is now 3.14. However,
          translation support is disabled with CMake versions
          older than 3.20.

        - The CMake-based build is now close to feature parity with the
          Autotools-based build. Most importantly a few tests aren't
          run yet. Testing the CMake-based build on different operating
          systems would be welcome now. See the comment at the top of
          CMakeLists.txt.

    * Fixed a bug in the Autotools feature test for ARM64 CRC32
      instruction support for old versions of Clang. This did not
      affect the CMake build.

    * Windows:

        - The build instructions in INSTALL and windows/INSTALL*.txt
          were revised completely.

        - windows/build-with-cmake.bat along with the instructions
          in windows/INSTALL-MinGW-w64_with_CMake.txt should make
          it very easy to build liblzma.dll and xz.exe on Windows
          using CMake and MinGW-w64 with either GCC or Clang/LLVM.

        - windows/build.bash was updated. It now works on MSYS2 and
          on GNU/Linux (cross-compiling) to create a .zip and .7z
          package for 32-bit and 64-bit x86 using GCC + MinGW-w64.

    * The TODO file is no longer installed as part of the
      documentation. The file is out of date and does not reflect
      the actual tasks that will be completed in the future.

    * Translations:

        - Translated lzmainfo man pages are now installed. These
          had been forgotten in earlier versions.

        - Updated Croatian, Esperanto, German, Hungarian, Korean,
          Polish, Romanian, Spanish, Swedish, Vietnamese, and Ukrainian
          translations.

        - Updated German, Korean, Romanian, and Ukrainian man page
          translations.

    * Added a few tests.

    Summary of new features added in the 5.5.x development releases:

    * liblzma:

        - LZMA decoder: Speed optimizations to the C code and
          added GCC & Clang compatible inline assembly for x86-64.

        - Added lzma_mt_block_size() to recommend a Block size for
          multithreaded encoding.

        - Added CLMUL-based CRC32 on x86-64 and E2K with runtime
          processor detection. Similar to CRC64, on 32-bit x86 it
          isn't available unless --disable-assembler is used.

        - Optimized the CRC32 calculation on ARM64 platforms using the
          CRC32 instructions. Runtime detection for the instruction is
          used on GNU/Linux, FreeBSD, Windows, and macOS. If the
          compiler flags indicate unconditional CRC32 instruction
          support (+crc) then the generic version is not built.

        - Added definitions of mask values like
          LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.

    * xz:

        - Multithreaded mode is now the default. This improves
          compression speed and creates .xz files that can be
          decompressed in multithreaded mode. The downsides are
          increased memory usage and slightly worse compression ratio.

        - Added a new command line option --filters to set the filter
          chain using the liblzma filter string syntax.

        - Added new command line options --filters1 ... --filters9 to
          set additional filter chains using the liblzma filter string
          syntax. The --block-list option now allows specifying filter
          chains that were set using these new options.

        - Ported the command line tools to Windows MSVC.
          Visual Studio 2015 or later is required.

    * Added lz4 support to xzdiff/xzcmp and xzgrep.


5.5.2beta (2024-02-14)

    * Licensing change: The core components are now under the
      BSD Zero Clause License (0BSD). In XZ Utils 5.4.6 and older
      and 5.5.1alpha these components are in the public domain and
      obviously remain so; the change affects the new releases only.

      0BSD is an extremely permissive license which doesn't require
      retaining or reproducing copyright or license notices when
      distributing the code, thus in practice there is extremely
      little difference to public domain.

    * liblzma

        - Significant speed optimizations to the LZMA decoder were
          made. There are now three variants that can be chosen at
          build time:

            * Basic C version: This is a few percent faster than
              5.4.x due to some new optimizations.

            * Branchless C: This is currently the default on platforms
              for which there is no assembly code. This should be a few
              percent faster than the basic C version.

            * x86-64 inline assembly. This works with GCC and Clang.

          The default choice can currently be overridden by setting
          LZMA_RANGE_DECODER_CONFIG in CPPFLAGS: 0 means the basic
          version and 3 means that branchless C version.

        - Optimized the CRC32 calculation on ARM64 platforms using the
          CRC32 instructions. The instructions are optional in ARMv8.0
          and are required in ARMv8.1 and later. Runtime detection for
          the instruction is used on GNU/Linux, FreeBSD, Windows, and
          macOS. If the compiler flags indicate unconditional CRC32
          instruction support (+crc) then the generic version is not
          built.

    * Added lz4 support to xzdiff/xzcmp and xzgrep.

    * Man pages of xzdiff/xzcmp, xzgrep, and xzmore were rewritten
      to simplify licensing of the man page translations.

    * Translations:

        - Updated Chinese (simplified), German, Korean, Polish,
          Romanian, Spanish, Swedish, and Ukrainian translations.

        - Updated German, Korean, Romanian, and Ukrainian man page
          translations.

    * Small improvements to the tests.

    * Added doc/examples/11_file_info.c. It was added to the Git
      repository in 2017 but forgotten to be added into distribution
      tarballs.

    * Removed doc/examples_old. These were from 2012.

    * Removed the macos/build.sh script. It had not been updated
      since 2013.


5.5.1alpha (2024-01-26)

    * Added a new filter for RISC-V binaries. The filter can be used
      for 32-bit and 64-bit binaries with either little or big
      endianness. In liblzma, the Filter ID is LZMA_FILTER_RISCV (0x0B)
      and the xz option is --riscv. liblzma filter string syntax
      recognizes this filter as "riscv".

    * liblzma:

        - Added lzma_mt_block_size() to recommend a Block size for
          multithreaded encoding

        - Added CLMUL-based CRC32 on x86-64 and E2K with runtime
          processor detection. Similar to CRC64, on 32-bit x86 it
          isn't available unless --disable-assembler is used.

        - Implemented GNU indirect function (IFUNC) as a runtime
          function dispatching method for CRC32 and CRC64 fast
          implementations on x86. Only GNU/Linux (glibc) and FreeBSD
          builds will use IFUNC, unless --enable-ifunc is specified to
          configure.

        - Added definitions of mask values like
          LZMA_INDEX_CHECK_MASK_CRC32 to <lzma/index.h>.

        - The XZ logo is now included in the Doxygen generated
          documentation. It is licensed under Creative Commons
          Attribution-ShareAlike 4.0.

    * xz:

        - Multithreaded mode is now the default. This improves
          compression speed and creates .xz files that can be
          decompressed multithreaded at the cost of increased memory
          usage and slightly worse compression ratio.

        - Added new command line option --filters to set the filter
          chain using liblzma filter string syntax.

        - Added new command line options --filters1 ... --filters9 to
          set additional filter chains using liblzma filter string
          syntax. The --block-list option now allows specifying filter
          chains that were set using these new options.

        - Added support for Linux Landlock as a sandboxing method.

        - xzdec now supports pledge(2), Capsicum, and Linux Landlock as
          sandboxing methods.

        - Progress indicator time stats remain accurate after pausing
          xz with SIGTSTP.

        - Ported xz and xzdec to Windows MSVC. Visual Studio 2015 or
          later is required.

    * CMake Build:

        - Supports pledge(2), Capsicum, and Linux Landlock sandboxing
          methods.

        - Replacement functions for getopt_long() are used on platforms
          that do not have it.

    * Enabled unaligned access by default on PowerPC64LE and on RISC-V
      targets that define __riscv_misaligned_fast.

    * Tests:

        - Added two new fuzz targets to OSS-Fuzz.

        - Implemented Continuous Integration (CI) testing using
          GitHub Actions.

    * Changed quoting style from `...' to '...' in all messages,
      scripts, and documentation.

    * Added basic Codespell support to help catch typo errors.

xz: updated to 5.4.6

5.4.6 (2024-01-26)

* Fixed a bug involving internal function pointers in liblzma not
  being initialized to NULL. The bug can only be triggered if
  lzma_filters_update() is called on a LZMA1 encoder, so it does
  not affect xz or any application known to us that uses liblzma.

* xz:

    - Fixed a regression introduced in 5.4.2 that caused encoding
      in the raw format to unnecessarily fail if --suffix was not
      used. For instance, the following command no longer reports
      that --suffix must be used:

          echo foo | xz --format=raw --lzma2 | wc -c

    - Fixed an issue on MinGW-w64 builds that prevented reading
      from or writing to non-terminal character devices like NUL.

* Added a new test.

xz: updated to 5.4.5

5.4.5

* liblzma:

    - Use __attribute__((__no_sanitize_address__)) to avoid address
      sanitization with CRC64 CLMUL. It uses 16-byte-aligned reads
      which can extend past the bounds of the input buffer and
      inherently trigger address sanitization errors. This isn't
      a bug.

    - Fixed an assertion failure that could be triggered by a large
      unpadded_size argument. It was verified that there was no
      other bug than the assertion failure.

    - Fixed a bug that prevented building with Windows Vista
      threading when __attribute__((__constructor__)) is not
      supported.

* xz now properly handles special files such as "con" or "nul" on
  Windows. Before this fix, the following wrote "foo" to the
  console and deleted the input file "con_xz":

      echo foo | xz > con_xz
      xz --suffix=_xz --decompress con_xz

* Build systems:

    - Allow builds with Windows win95 threading and small mode when
      __attribute__((__constructor__)) is supported.

    - Added a new line to liblzma.pc for MSYS2 (Windows):

          Cflags.private: -DLZMA_API_STATIC

      When compiling code that will link against static liblzma,
      the LZMA_API_STATIC macro needs to be defined on Windows.

    - CMake specific changes:

        * Fixed a bug that allowed CLOCK_MONOTONIC to be used even
          if the check for it failed.

        * Fixed a bug where configuring CMake multiple times
          resulted in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC
          not being set.

        * Fixed the build with MinGW-w64-based Clang/LLVM 17.
          llvm-windres now has more accurate GNU windres emulation
          so the GNU windres workaround from 5.4.1 is needed with
          llvm-windres version 17 too.

        * The import library on Windows is now properly named
          "liblzma.dll.a" instead of "libliblzma.dll.a"

        * Fixed a bug causing the Ninja Generator to fail on
          UNIX-like systems. This bug was introduced in 5.4.0.

        * Added a new option to disable CLMUL CRC64.

        * A module-definition (.def) file is now created when
          building liblzma.dll with MinGW-w64.

        * The pkg-config liblzma.pc file is now installed on all
          builds except when using MSVC on Windows.

        * Added large file support by default for platforms that
          need it to handle files larger than 2 GiB. This includes
          MinGW-w64, even 64-bit builds.

* Small fixes and improvements to the tests.

* Updated translations: Chinese (simplified) and Esperanto.

xz: updated to 5.4.4

5.4.4 (2023-08-02)

* liblzma and xzdec can now build against WASI SDK when threading
  support is disabled. xz and tests don't build yet.

* CMake:

    - Fixed a bug preventing other projects from including liblzma
      multiple times using find_package().

    - Don't create broken symlinks in Cygwin and MSYS2 unless
      supported by the environment. This prevented building for the
      default MSYS2 environment. The problem was introduced in
      xz 5.4.0.

* Documentation:

    - Small improvements to man pages.

    - Small improvements and typo fixes for liblzma API
      documentation.

* Tests:

    - Added a new section to INSTALL to describe basic test usage
      and address recent questions about building the tests when
      cross compiling.

    - Small fixes and improvements to the tests.

* Translations:

    - Fixed a mistake that caused one of the error messages to not
      be translated. This only affected versions 5.4.2 and 5.4.3.

    - Updated the Chinese (simplified), Croatian, Esperanto, German,
      Korean, Polish, Romanian, Spanish, Swedish, Ukrainian, and
      Vietnamese translations.

    - Updated the German, Korean, Romanian, and Ukrainian man page
      translations.

xz: updated to 5.4.2

5.4.2 (2023-03-18)

* 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.

xz: updated to 5.4.1

5.4.1 (2023-01-11)

    * 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.

        - Windows / Visual Studio: Workaround a possible compiler bug
          when targeting 32-bit x86 and compiling the CLMUL version of
          the CRC64 code. The CLMUL code isn't enabled by the Windows
          project files but it is in the CMake-based builds.

    * Build systems:

        - Windows-specific CMake changes:

            * Don't try to enable CLMUL CRC64 code if _mm_set_epi64x()
              isn't available. This fixes CMake-based build with Visual
              Studio 2013.

            * Created a workaround for a build failure with windres
              from GNU binutils. It is used only when the C compiler
              is GCC (not Clang). The workaround is incompatible
              with llvm-windres, resulting in "XZx20Utils" instead
              of "XZ Utils" in the resource file, but without the
              workaround llvm-windres works correctly. See the
              comment in CMakeLists.txt for details.

            * Included the resource files in the xz and xzdec build
              rules. Building the command line tools is still
              experimental but possible with MinGW-w64.

        - Visual Studio: Added stream_decoder_mt.c to the project
          files. Now the threaded decompressor lzma_stream_decoder_mt()
          gets built. CMake-based build wasn't affected.

        - Updated windows/INSTALL-MSVC.txt to mention that CMake-based
          build is now the preferred method with Visual Studio. The
          project files will probably be removed after 5.4.x releases.

        - Changes to #defines in config.h:

            * HAVE_DECL_CLOCK_MONOTONIC was replaced by
              HAVE_CLOCK_MONOTONIC. The old macro was always defined
              in configure-generated config.h to either 0 or 1. The
              new macro is defined (to 1) only if the declaration of
              CLOCK_MONOTONIC is available. This matches the way most
              other config.h macros work and makes things simpler with
              other build systems.

            * HAVE_DECL_PROGRAM_INVOCATION_NAME was replaced by
              HAVE_PROGRAM_INVOCATION_NAME for the same reason.

    * 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:

xz: updated to 5.4.0

5.4.0 (2022-12-13)

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.

Since 5.3.5beta:

* All fixes from 5.2.10.

* The ARM64 filter is now stable. The xz option is now --arm64.
  Decompression requires XZ Utils 5.4.0. In the future the ARM64
  filter will be supported by XZ for Java, XZ Embedded (including
  the version in Linux), LZMA SDK, and 7-Zip.

* Translations:

    - Updated Catalan, Croatian, German, Romanian, and Turkish
      translations.

    - Updated German man page translations.

    - Added Romanian man page translations.

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").

xz: updated to 5.2.9

5.2.9 (2022-11-30)

* liblzma:

- Fixed an infinite loop in LZMA encoder initialization
  if dict_size >= 2 GiB. (The encoder only supports up
  to 1536 MiB.)

- 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.

xz: updated to 5.2.8

5.2.8 (2022-11-13)

* 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.

xz: updated to 5.2.7

5.2.7 (2022-09-30)

* liblzma:

    - Made lzma_filters_copy() to never modify the destination
      array if an error occurs. lzma_stream_encoder() and
      lzma_stream_encoder_mt() already assumed this. Before this
      change, if a tiny memory allocation in lzma_filters_copy()
      failed it would lead to a crash (invalid free() or invalid
      memory reads) in the cleanup paths of these two encoder
      initialization functions.

    - Added missing integer overflow check to lzma_index_append().
      This affects xz --list and other applications that decode
      the Index field from .xz files using lzma_index_decoder().
      Normal decompression of .xz files doesn't call this code
      and thus most applications using liblzma aren't affected
      by this bug.

    - Single-threaded .xz decoder (lzma_stream_decoder()): 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 decoder) this already worked correctly.

    - Fixed accumulation of integrity check type statistics in
      lzma_index_cat(). This bug made lzma_index_checks() return
      only the type of the integrity check of the last Stream
      when multiple lzma_indexes were concatenated. Most
      applications don't use these APIs but in xz it made
      xz --list not list all check types from concatenated .xz
      files. In xz --list --verbose only the per-file "Check:"
      lines were affected and in xz --robot --list only the "file"
      line was affected.

    - Added ABI compatibility with executables that were linked
      against liblzma in RHEL/CentOS 7 or other liblzma builds
      that had copied the problematic patch from RHEL/CentOS 7
      (xz-5.2.2-compat-libs.patch). For the details, see the
      comment at the top of src/liblzma/validate_map.sh.

      WARNING: This uses __symver__ attribute with GCC >= 10.
      In other cases the traditional __asm__(".symver ...")
      is used. Using link-time optimization (LTO, -flto) with
      GCC versions older than 10 can silently result in
      broken liblzma.so.5 (incorrect symbol versions)! If you
      want to use -flto with GCC, you must use GCC >= 10.
      LTO with Clang seems to work even with the traditional
      __asm__(".symver ...") method.

* xzgrep: Fixed compatibility with old shells that break if
  comments inside command substitutions have apostrophes (').
  This problem was introduced in 5.2.6.

* Build systems:

    - New #define in config.h: HAVE_SYMBOL_VERSIONS_LINUX

    - Windows: Fixed liblzma.dll build with Visual Studio project
      files. It broke in 5.2.6 due to a change that was made to
      improve CMake support.

    - Windows: Building liblzma with UNICODE defined should now
      work.

    - CMake files are now actually included in the release tarball.
      They should have been in 5.2.5 already.

    - Minor CMake fixes and improvements.

* Added a new translation: Turkish

xz: updated to 5.2.6

5.2.6 (2022-08-12)

* xz:

    - The --keep option now accepts symlinks, hardlinks, and
      setuid, setgid, and sticky files. Previously this required
      using --force.

    - 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.

    - Visual Studio: Use non-standard _MSVC_LANG to detect C++
      standard version in the lzma.h API header. It's used to
      detect when "noexcept" can be used.

* 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.

      This vulnerability was discovered by:
      cleemy desu wayo working with Trend Micro Zero Day Initiative

    - 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.

* Translations:

    - Added new translations: Catalan, Croatian, Esperanto,
      Korean, Portuguese, Romanian, Serbian, Spanish, Swedish,
      and Ukrainian

    - Updated the Brazilian Portuguese translation.

    - Added French man page translation. This and the existing
      German translation aren't complete anymore because the
      English man pages got a few updates and the translators
      weren't reached so that they could update their work.

* Build systems:

    - Windows: Fix building of resource files when config.h isn't
      used. CMake + Visual Studio can now build liblzma.dll.

    - Various fixes to the CMake support. Building static or shared
      liblzma should work fine in most cases. In contrast, building
      the command line tools with CMake is still clearly incomplete
      and experimental and should be used for testing only.

      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.

    - DOS build now requires DJGPP 2.05 instead of 2.04beta.
      A workaround for a locale problem with DJGPP 2.05 was added.

* xzgrep and other scripts:

    - Added a configure option --enable-path-for-scripts=PREFIX.
      It is disabled by default except on Solaris where the default
      is /usr/xpg4/bin. See INSTALL for details.

    - Added a workaround for a POSIX shell detection problem on
      Solaris.

* Build systems:

    - Added preliminary build instructions for z/OS. See INSTALL
      section 1.2.9.

    - Experimental CMake support was added. It should work to build
      static liblzma on a few operating systems. It may or may not
      work to build shared liblzma. On some platforms it can build
      xz and xzdec too but those are only for testing. See the
      comment in the beginning of CMakeLists.txt for details.

    - Visual Studio project files were updated.
      WindowsTargetPlatformVersion was removed from VS2017 files
      and set to "10.0" in the added VS2019 files. In the future
      the VS project files will be removed when CMake support is
      good enough.

    - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED,
      HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING.

    - autogen.sh has a new optional dependency on po4a and a new
      option --no-po4a to skip that step. This matters only if one
      wants to remake the build files. po4a is used to update the
      translated man pages but as long as the man pages haven't
      been modified, there's nothing to update and one can use
      --no-po4a to avoid the dependency on po4a.

* Translations:

    - XZ Utils translations are now handled by the Translation
      Project: https://translationproject.org/domain/xz.html

    - All man pages are now included in German too.

    - New xz translations: Brazilian Portuguese, Finnish,
      Hungarian, Chinese (simplified), Chinese (traditional),
      and Danish (partial translation)

    - Updated xz translations: French, German, Italian, and Polish

    - Unfortunately a few new xz translations weren't included due
      to technical problems like too long lines in --help output or
      misaligned column headings in tables. In the future, many of
      these strings will be split and e.g. the table column
      alignment will be handled in software. This should make the
      strings easier to translate.

xz: updated to 5.2.4

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.

    - Microsoft Visual Studio build files have been moved under
      windows/vs2013 and windows/vs2017.

* 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.

Updated archivers/xz to 5.2.3
-----------------------------
5.2.3 (2016-12-30)
    * xz:
        - Always close a file before trying to delete it to avoid
          problems on some operating system and file system combinations.

        - Fixed copying of file timestamps on Windows.

        - Added experimental (disabled by default) sandbox support using
          Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.

    * C99/C11 conformance fixes to liblzma. The issues affected at least
      some builds using link-time optimizations.

    * Fixed bugs in the rarely-used function lzma_index_dup().

    * Use of external SHA-256 code is now disabled by default.
      It can still be enabled by passing --enable-external-sha256
      to configure. The reasons to disable it by default (see INSTALL
      for more details):

        - Some OS-specific SHA-256 implementations conflict with
          OpenSSL and cause problems in programs that link against both
          liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
          are affected.

        - The internal SHA-256 is faster than the SHA-256 code in
          some operating systems.

    * Changed CPU core count detection to use sched_getaffinity() on
      GNU/Linux and GNU/kFreeBSD.

    * Fixes to the build-system and xz to make xz buildable even when
      encoders, decoders, or threading have been disabled from libilzma
      using configure options. These fixes added two new #defines to
      config.h: HAVE_ENCODERS and HAVE_DECODERS.

Changes 5.2.0:
* liblzma:
        - Added support for multi-threaded compression. See the
          lzma_mt structure, lzma_stream_encoder_mt(), and
          lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
          lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
          in <lzma/hardware.h> for details.
        - 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.
        - liblzma (not the whole XZ Utils) should now be buildable
          with MSVC 2013 update 2 or later using windows/config.h.
* 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.
        - 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.

Changes since 1.9: +4 -4 lines

Changes 5.0.5:

* 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.

Changes 5.0.4:

  - 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.

Changes 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.

Changes 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.

Changes 5.0.0:
* The memory usage limit is now disabled by default.
* Added support for XZ_DEFAULTS environment variable.
* The compression settings associated with the preset levels
  -0 ... -9 have been changed. --extreme was changed a little too.
* 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.
* 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 Utils 4.999.9beta was released on 2009-08-27. Among many less
important changes, this release fixes a data corruption in the
compression code.  (The bug was specific to XZ Utils and was not
present in 7-Zip or LZMA SDK.) Everyone using an older version of
XZ Utils should upgrade.

This is the last beta release before XZ Utils 5.0.0. No big changes
are planned before the first stable release.
