  [ Helmut Grohne ]
  * Non-maintainer upload.

  [ Colin Watson ]
  * Remove build-dependency on perl; we use no non-trivial Perl modules so
    the Essential perl-base is perfectly adequate, and an unadorned
    build-dependency on perl is problematic for cross-building.

xz-utils (5.1.1alpha+20120614-2) unstable; urgency=low

  * Apply fixes from 5.1.2alpha.  Closes: #685220.
    - liblzma: report a LZMA_DATA_ERROR when range encoded data starts
      with a nonzero byte.  This is a sanity check to catch malformed
      files that no known encoders produce.
    - xz -v -v --list: Support for decompressing blocks with
      zero-length uncompressed data was added in xz 5.0.2, not 5.0.3.
    - xz.1: "xz --robot -v -v --list" gained a "minimum xz version to
      decompress" field.
  * xz-utils/README.Debian: Document differences from upstream.
    Closes: #685217.

xz-utils (5.1.1alpha+20120614-1) unstable; urgency=low

  * New snapshot, taken from upstream commit f1675f76.
    - liblzma: BCJ filters would return a spurious LZMA_BUF_ERROR
      result in certain circumstances.  As a result, the xz tool
      could produce inappropriate "Compressed data is corrupt" or
      "Unexpected end of input" failures (reported in XZ Embedded as
      Fedora bug 735408).
    - "xz -v -v --list" prints the minimal XZ Utils version needed
      to decompress a stream.
    - "xz --robot -v --list" formats filenames more plainly.
    - xzgrep does not fail unconditionally when the decompressor
      dies with SIGPIPE due to unconsumed output any more.  This
      makes the exit status from commands such as "xzgrep -q" and
      "xzgrep -l" more predictable and convenient for scripts.
    - examples/xz_pipe_decomp.c did not check correctly for
      truncated input.
    - There is a new set of sample programs.  The old ones have
      been renamed to examples_old but are still maintained.
  * liblzma:
    - If dlopen() indicates that liblzma.so.2 is loaded, check fewer
      reserved fields in the stream argument to the lzma_code()
      function.  This prevents out-of-bounds reads when liblzma5
      functions are called by code built against liblzma2 (see
      <http://sourceware.org/PR12977>).
    - Remove the lzma_code@Base compatibility symbol.
      Closes: #649522.  Thanks to Eduard Bloch.
    - Install run-time library to /lib so it can be used before /usr
      is mounted.  Closes: #672120.
    - Configure with --disable-threads for now to avoid needlessly
      linking to libpthread and librt.
  * liblzma-dev:
    - Install an appropriate library for static linking instead of
      the decompression-only version used to build xzdec.
      Closes: #673001.  Thanks to Anton Tolchanov.
    - Use the liblzma2-compatible version of lzma_code() in the
      static library.
    - Multi-Arch: same.  Thanks to Riku Voipio.
    - Install new examples and revised old examples to
      /usr/share/doc/liblzma-dev.
  * xz-utils:
    - Use update-alternatives to provide lzma, unlzma, lzcat, and
      the rest of the lz* scripts without conflicting with the lzma
      package.
    - Conflicts: lzma versions before before 9.22-1, when it started
      providing lzma, unlzma, and lzcat through the alternatives
      system.
    - Conflicts: and Replaces: xz-lzma.
    - README.Debian: Update instructions on configuring the package
      to provide lzma compatibility commands.
  * Remove xz-lzma package.
  * Use dpkg-buildflags to retrieve compiler flags, including
    hardening options.  Build-Depends: dpkg-dev (>= 1.16.1).
    Closes: #653739.
  * debian/rules:
    - build-arch: Simplify by using a double-colon rule instead of a
      dependency on a dummy noop target.
    - build-indep: Assume doxygen is available, instead of trying to
      get by by assuming the caller meant to invoke build-arch when
      it is missing.  Build-Depends: dpkg-dev (>= 1.16.2).
    - Rearrange for clarity.
  * debian/symbols: Bump the minimal version for lzma_code(),
    lzma_raw_buffer_decode(), and lzma_raw_buffer_encode().
  * Use machine-readable copyright-format 1.0.
  * Update copyright file.
  * Standards-Version: 3.9.3 (checked).
  * debian/changelog.upstream.sh: Use ‘git rev-list | git diff-tree’
    instead of ‘git log’ to avoid depending on the build system’s
    configuration.

xz-utils (5.1.1alpha+20110809-3) unstable; urgency=low

  * liblzma: Match upstream ABI.
    - Remove the lzma_chunk_size() function.
    - A few ABI tweaks to reserved space in structures.
    - Enable ELF symbol versioning.
    - Bump soname to 5.
    - Continue to leave out threading support, since the relevant
      interfaces in liblzma are not yet stable.
  * xz-utils/README.Debian: Remove note on ABI differences.
  * Remove liblzma/README.Debian.
  * liblzma: Introduce a lzma_code@Base compatibility symbol to ensure
    programs linked against unversioned symbols from liblzma2 can
    share a process image with liblzma5 without breaking.
  * debian/symbols: XZ_5.0 symbols come from liblzma5.  Build-Depends:
    dpkg-dev (>= 1.15.6); thanks to Jakub Wilk for a reminder.
  * debian/symbols: The lzma_code@Base symbol is not guaranteed to
    continue to exist in the future, so tell dpkg-shlibdeps to produce
    an error if some package manages to use it.

xz-utils (5.1.1alpha+20110809-1) unstable; urgency=low

  * New snapshot, taken from upstream commit 5c5b225.
    - liblzma:
      - lzma_stream_encoder() leaked memory.
      - The LZMA2 decoder rejected streams that decompress to a
        zero-length string.
      - lzma_easy_buffer_encode() and lzma_stream_buffer_encode()
        used to write such streams when asked to compress a 0-length
        buffer.
      - lzma_index_init() would segfault on allocation failure.
      - liblzma: Various functions check their arguments (especially
        choice of integrity check) better, making it harder to create
        a corrupt .xz file instead of receiving an error.
    - xz and scripts:
      - "xz -v -v --list" would read and try to free() uninitialized
        memory, continuing past the end of an on-stack array, when
        asked to describe certain corrupted XZ files.
      - xz -S.suf now refuses to compress a file whose name already
        ends with the suffix “.suf”.
      - xz --force can be used to compress setuid, setgid, sticky,
        and multiply linked files.
      - xz uses posix_fadvise() to speed up sequential input.
      - xz --block-size forces a full flush periodically during
        compression, for better random-access reading support and to
        make simple parallelism possible in the future.
      - unxz: The new --single-stream option discards trailing
        garbage after the end of the first stream.
      - xzdiff can read gzip- and bzip2-compressed files.
      - xzdiff and xzgrep can read lzop-compressed files.
      - xzegrep and xzfgrep perform extended regex and fixed-string
        matches, respectively.  (The previous behavior was to always
        use basic regexes.)
      - xzgrep -l (= --files-with-match) works.
      - The Czech “xz --help” output uses a more correct term for
        files with holes.  Thanks to Petr Hubený.  Closes: #605762.
      - xz: New Polish and French translations.
    - The Doxygen-generated documentation uses short, relative paths
      to name source files.  Closes: #572273.
  * Update copyright file.
  * Remove example programs from debian/examples.  They are included
    in the upstream source package now.
  * Move liblzma to an architecture-specific directory, so the
    native library and foreign-architecture versions can be installed
    simultaneously.
    - liblzma2: Pre-Depends: multiarch-support.
    - Use debhelper compatibility level 9.  This requires passing
      the dh sequence name before other options when invoking dh in
      debian/rules.  Build-Depends: debhelper (>= 8.1.3).
    - liblzma2, liblzma-dev: Install files under /usr/lib/<triplet>
      instead of /usr/lib.
    - Thanks to Steve Langasek for explaining the process on the
      Debian wiki.
  * Standards-Version: 3.9.2 (checked).
  * debian/control: liblzma2 is Multi-Arch: same, while xz-utils
    and xzdec are Multi-Arch: foreign.  Closes: #637883.  Thanks to
    Riku Voipio.
  * debian/symbols: Bump the minimal version for LZMA2 encoder
    functions that reject more bad arguments and skip empty blocks.
  * debian/rules: ./configure --disable-symbol-versions for now.
  * debian/rules: Provide build-arch and build-indep targets that
    only build the code and the API documentation, respectively.
    Thanks to Roger Leigh for suggesting it through lintian.
    Build-Depends: debhelper (>= 8.9.0).
  * debian/rules: Treat DEB_BUILD_OPTIONS=nocheck as a request not to
    run build-time tests.  Thanks to Thorsten Glaser for a reminder.
    Closes: #627209.

xz-utils (5.0.0-1) experimental; urgency=low

  * Upload to experimental.
  * New stable upstream release.  Closes: #592298.
    - xz avoids SA_RESTART.  This should not have a visible effect
      because xz already blocked signals during operations that
      would be difficult to resume after interruption.
    - liblzma: The coders returned by lzma_index_encoder() and
      lzma_index_decoder() support an LZMA_FINISH action, with
      identical semantics to LZMA_RUN.
    - The printable (PDF and PS) versions of the manual are easier

xz-utils (4.999.9beta+20100903-1) experimental; urgency=low

  * New snapshot, taken from upstream commit 373ee26.
    - liblzma: The settings for compression levels 0 through 5
      (used by xz -0/.../-5) have been tweaked.  This affects the
      speed, compression ratio, and memory usage at compression and
      decompression time.
    - Does not search so hard for a match when a low "nice match
      length" setting is specified without a depth.
    - xz: The -1/.../-9 preset options override any previously
      specified filters, rather than vice versa.  To mix presets
      with filter options, use the --lzma2=preset=n option.
    - xz: Warns about --memlimit-compress settings that result in
      compression settings changing even if no explicit -1/.../-9,
      --lzma1, or --lzma2 option was used.
    - "xz -v -v --compress" now prints an estimate of the memory
      required to decompress a file.
  * debian/copyright: Update upstream Git URL.
  * debian/changelog.upstream.sh: Permit terser changelog lines.
  * Standards-Version: 3.9.1 (checked).

  * New upstream snapshot, taken from upstream commit d5653ba8a.
    - xz: The memory usage limiter is now disabled by default.
    - xz: Support for an XZ_DEFAULTS environment variable was added.
      It contains user-specific default settings, such as memory usage
      limits, and can be overridden by the command line and XZ_OPT.
    - xz: The new --memlimit-compress and --memlimit-decompress
      options allow the memory usage limit to be set separately for
      compression and decompression.  A new --memlimit alias has been
      added for the existing --memory option.
    - xz: The --info-memory option (with or without --robot) now prints
      how much RAM is installed in addition to the compression and
      decompression memory limits.
  * liblzma-doc: Simplify package description.
  * debian/control: Build-Depends: autopoint | gettext (<< 0.18-1),
    autopoint | cvs instead of autopoint, to help with backporting.

  * xz-utils: NEWS.Debian.gz: Clarify how interleaved output can
    go wrong.
  * debian/rules: Simplify:
     - remove support for comma as a delimiter for $(DEB_BUILD_OPTIONS).
     - rely on dh --parallel instead of tricky logic of our own to
       handle parallel builds.  Build-Depends: debhelper (>= 7.4.10).

xz-utils (4.999.9beta+20100117-1) unstable; urgency=low

  * New upstream snapshot, taken from upstream commit 07a11dad.
     + Fix some logic errors in the internal memory usage configuration
       API.
     + xz will no longer compress or decompress special files in place,
       even with --force.
       --force still enables compression of the target of a symlink.
     + xz will no longer read compressed data from a terminal or write
       it to a terminal, even with --force.
     + liblzma: many Index handling API improvements:
        - An lzma_index includes more useful metadata that is not
          actually from the Index.  This is particularly helpful for
          describing multiple-stream files.
           * lzma_index_cat() does not take a stream padding argument
             any more; use lzma_index_stream_padding() instead.
           * lzma_index_memusage() takes two arguments now.
             The new lzma_index_memused() convenience function
             calculates the total memory usage of an lzma_index.
           * lzma_index_count() has been replaced with
             lzma_index_block_count() and lzma_index_stream_count().
           * The new lzma_index_stream_flags() allows storing Stream
             Flags (e.g., checksum types) with the Index information.
           * The new lzma_index_checks() function indicates the list of
             checksum types in use.
           * lzma_index_equal() has been removed.  Its semantics were
             unclear, and something approximately equivalent can be
             implemented by iterating over Blocks in application code.
        - An lzma_index no longer represents a position within an Index.
          The new lzma_index_iter type can be used for that purpose.
           * Certain functions generate an iterator on demand now rather
             than clobbering their lzma_index arguments.  Using a single
             lzma_index for multiple concurrent invocations is safe now:
              lzma_index_buffer_encode(), lzma_index_encoder()
           * Functions that used to specify a Record by modifying an
             lzma_index argument have been renamed and taught to write
             an lzma_index_iter instead:
              lzma_index_locate() -> lzma_index_iter_locate()
              lzma_index_rewind() -> lzma_index_iter_rewind()
              lzma_index_read() -> lzma_index_iter_next()
           * The lzma_index_record type used by lzma_index_read() for
             complex seeks is no more.  lzma_index_iter_next() instead
             takes a parameter of the new lzma_index_iter_mode type.
           * New function: lzma_index_iter_init()
           * lzma_index_init() cannot reuse memory from an existing
             lzma_index any more.  The signature changed accordingly.
     + xz: support for decompressing to a sparse file
        - Try to write a sparse file if the decompressed stream contains
          long runs of null bytes.
        - The new --no-sparse option disables this behavior.
     + xz: add Czech translation.
     + liblzma-dev: lzma_filters_copy() and lzma_filters_update() are
       declared not to throw exceptions.
  * liblzma: bump soname.
  * xz-utils: Add NEWS.Debian describing the sparse file support.
  * debian/rules: Stop explicitly disabling assembler optimizations on
    the Hurd.  The configure script will check if a platform is
    supported.

  * debian/rules: Update clean target to handle comments and wildcards
    in .gitignore.
  * Build-Depends: perl.

  * debian/rules: Speed up build by using autoreconf --symlink.
  * Remove debian/dirs lists.
  * Update copyright file and fix a small typo.

xz-utils (4.999.9beta+20091116-1) unstable; urgency=low

  * New upstream snapshot, taken from upstream commit d315ca4.
     + liblzma: add some new functions:
        - lzma_filters_copy() to copy a filter chain;
        - lzma_filters_update() to change compression options mid-stream;
        - lzma_physmem() to retrieve the total quantity of installed RAM.
     + Fix a design error in liblzma API.
        - Stop requiring caller to maintain filter chain during
          compression.  The library used to read it for new compression
          options.  Callers that need to change options mid-stream should
          use lzma_filters_update() instead.
        - Remove 'persistent' member from struct lzma_options_lzma.
     + xz: add --robot --info-memory options, for front-ends to use to
       read the memory usage limit.
  * liblzma: bump soname; add README.Debian explaining why soname
    differs from upstream.
  * Use source format 3.0 (quilt).
  * Update and clarify copyright file.
