+XZ Utils sources for Debian
+---------------------------
+
+This Debian package is developed in a public Git repository (see the Vcs-Git
+field of debian/control) based on XZ Utils’s repository on tukaani.org.
+To build from a git checkout:
+
+	debian/rules get-orig-source
+	mv xz-utils_*.tar.gz ..
+	debian/autogen.sh
+	debuild
+
+To build a released version, no special instructions apply.
+“dpkg-buildpackage” and “apt-get -b xz-utils” should work as usual.

+xz-utils (5.0.0-2.1) stable; urgency=low
+
+  * Fixes from upstream:
+    * liblzma:
+      - lzma_easy_buffer_encode() and lzma_stream_buffer_encode()
+        avoid writing Blocks with empty compressed data that xz and
+        liblzma versions before 5.0.2 cannot read.
+      - The LZMA2 decoder skips Blocks with empty compressed data
+        instead of rejecting them.
+      - Validates encoder arguments better.  It is harder to segfault
+        or create a corrupt XZ file instead of receiving an error
+        when calling these functions:
+        - lzma_stream_buffer_encode() and lzma_block_buffer_encode()
+          reject unsupported integrity checks;
+        - lzma_block_encoder() checks for block == NULL.
+      - bcj: Fix possibility of incorrect LZMA_BUF_ERROR (reported in
+        XZ Embedded as Fedora bug 735408).
+      - Plugs a memory leak in lzma_stream_encoder().
+      - lzma_index_init() returns NULL instead of segfaulting on
+        allocation failure.
+    * docs/examples/xz_pipe_decompress.c checks that the last
+      lzma_code() call returned LZMA_STREAM_END, since otherwise the
+      compressed file ended without a proper footer.
+    * "xz -v -v --list" does not free() filter options unless the
+      filter options array has been initialized.  This prevents
+      reading and free()ing pointers from past the end of an on-stack
+      array when one of the listed files has an unmeaningful Block
+      header size.
+    * xzegrep and xzfgrep perform extended regex and fixed-string
+      matches, respectively.  (The previous behavior was to always
+      use basic regexes.)
+    * The exit status from “xzdiff foo.xz bar.xz” reflects whether
+      files differ.  Thanks to Peter Pallinger.  Closes: #635501.
+    * xzgrep does not fail just because the decompressor has died
+      with SIGPIPE due to some unconsumed output.  This makes the
+      exit status from commands such as "xzgrep -q" more predictable.
+    * The Czech “xz --help” output uses a more correct term for files
+      with holes.  Thanks to Petr Hubený.  Closes: #605762.
+    * The Italian diagnostic for an invalid --format argument lost an
+      extra 'N'.
+  * debian/rules: "chmod +x tests/test_scripts.sh" for new xzdiff
+    tests.
+  * debian/symbols: Bump the minimal versions for LZMA2 encoder
+    functions that reject more bad arguments and skip empty blocks.
+  * liblzma-dev: Install an appropriate library for static linking
+    instead of the decompression-only version used to build xzdec.
+    Thanks to Anton Tolchanov.  Closes: #673001.

+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
+      to read.
+    - Many documentation and build system cleanups.
+  * liblzma: Back out upstream ABI tweaks.
+  * liblzma/README.Debian: Document ABI differences from upstream.

+xz-utils (4.999.9beta+20100927-1) experimental; urgency=low
+
+  * New snapshot, taken from upstream commit cec0ddc.
+    - liblzma: The meaning of --extreme has been tweaked to address
+      cases in which it made the compression ratio worse.  Some files
+      might benefit slightly less from --extreme.
+    - xz: Table columns are not misaligned any more in messages with

+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.

+xz-utils (4.999.9beta+20100810-1) unstable; urgency=low
+
+  * 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.
+    Thanks to Thorsten Glaser for a report.

+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.

+Format-Specification: http://svn.debian.org/wsvn/dep/web/deps/dep5.mdwn?rev=135
+Name: XZ Utils
+Maintainer: Lasse Collin <lasse.collin@tukaani.org>
+Source: http://tukaani.org/xz
+ http://git.tukaani.org/xz.git
+X-Authors:
+ XZ Utils is developed and maintained upstream by Lasse Collin.  Major
+ portions are based on code by other authors; see AUTHORS for details.
+ Most of the source has been put into the public domain, but some files
+ have not (details below).
+X-Overview:
+ Different licenses apply to different files in this package. Here
+ is a rough summary of which licenses apply to which parts of this
+ package (but check the individual files to be sure!):
+ .
+   - liblzma is in the public domain.
+ .
+   - xz, xzdec, and lzmadec command line tools are in the public
+     domain unless GNU getopt_long had to be compiled and linked
+     in from the lib directory. The getopt_long code is under
+     GNU LGPLv2.1+.
+ .
+   - The scripts to grep, diff, and view compressed files have been
+     adapted from gzip. These scripts and their documentation are
+     under GNU GPLv2+.
+ .
+   - All the documentation in the doc directory and most of the
+     XZ Utils specific documentation files in other directories
+     are in the public domain.
+ .
+   - Translated messages are in the public domain.
+ .
+   - The build system contains public domain files, and files that
+     are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
+     in the binaries being built.
+ .
+   - Test files and test code in the tests directory, and debugging
+     utilities in the debug directory are in the public domain.
+ .
+   - The extra directory may contain public domain files, and files
+     that are under various free software licenses.
+ .
+ You can do whatever you want with the files that have been put into
+ the public domain. If you find public domain legally problematic,
+ take the previous sentence as a license grant. If you still find
+ the lack of copyright legally problematic, you have too many
+ lawyers.
+ .
+ As usual, this software is provided "as is", without any warranty.
+ .
+ If you copy significant amounts of public domain code from XZ Utils
+ into your project, acknowledging this somewhere in your software is
+ polite (especially if it is proprietary, non-free software), but
+ naturally it is not legally required. Here is an example of a good
+ notice to put into "about box" or into documentation:
+ .
+     This software includes code from XZ Utils <http://tukaani.org/xz/>.
+ .
+ The following license texts are included in the following files:
+   - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
+   - COPYING.GPLv2: GNU General Public License version 2
+   - COPYING.GPLv3: GNU General Public License version 3
+ .
+ Note that the toolchain (compiler, linker etc.) may add some code
+ pieces that are copyrighted. Thus, it is possible that e.g. liblzma
+ binary wouldn't actually be in the public domain in its entirety
+ even though it contains no copyrighted code from the XZ Utils source
+ package.
+ .
+ If you have questions, don't hesitate to ask the author(s) for more
+ information.
+X-Note:
+ The rest of this file only describes the source package.  The binary
+ packages contain some files derived from other works: for example,
+ all images in the API documentation come from Doxygen.

+ COPYING says that most docs are in the public domain. Maybe that's not
+ clear enough, but on the other hand it looks a bit stupid to put
+ copyright information in tiny and relatively small docs like README.
+ .
+ I don't dare to say that _all_ XZ Utils specific docs are in the public
+ domain unless otherwise mentioned in the file. I'm including PDF files
+ generated by groff + ps2pdf, and some day I might include Doxygen-
+ generated HTML docs too. Those don't include any copyright notices, but
+ it seems likely that groff + ps2pdf or at least Doxygen put some
+ copyrighted content into the generated files.

+liblzma for Debian
+------------------
+
+liblzma2 in Debian is not ABI-compatible with upstream's library and
+is not likely to be ABI-compatible with liblzma from other
+distributions:
+
+ * The lzma_stream, lzma_stream_flags, and lzma_options_lzma
+   structures are not layout-compatible with upstream.  The versions
+   in Debian have fewer fields reserved for future expansion.
+
+ * The lzma_chunk_size() function is present but useless in Debian.
+   It has been removed upstream.
+
+ * The library soname is liblzma.so.2 in Debian, liblzma.so.5
+   upstream.
+
+To use binaries pre-built for other distributions, you can install a
+copy of liblzma.so.5:
+
+ apt-get build-dep xz-utils
+ apt-get source --download-only xz-utils
+ tar -xf xz-utils_*.orig.tar.gz
+ cd xz-5*
+ autoreconf -fis
+ ./configure --prefix=/usr/local --disable-xz --disable-xzdec \
+	--disable-lzmadec --disable-lzmainfo --disable-lzma-links \
+	--disable-scripts
+ make install

+Subject: Set liblzma version-info to 2:0:0
+
+This change is Debian-specific.
+
+The upstream version-info is 5:0:0, but Debian has been
+using version 2 for a while and it is simplest to avoid
+breaking ABI.
+
+With commit 418d64a (Fix a design error in liblzma API,
+2009-11-14) the lzma_options_lzma data structure was changed.
+Programs that read or write its fields will have no hope of
+working with older liblzma versions.
+
+With commit 1a7ec87 (Revised the Index handling code.,
+2009-12-31) various functions were removed.  Programs that
+used them will not work with the current library, so that
+required bumping the soname for a second time.

+Subject: liblzma: Fix possibility of incorrect LZMA_BUF_ERROR.
+
+lzma_code() could incorrectly return LZMA_BUF_ERROR if
+all of the following was true:
+
+  - The caller knows how many bytes of output to expect
+    and only provides that much output space.
+
+  - When the last output bytes are decoded, the
+    caller-provided input buffer ends right before
+    the LZMA2 end of payload marker. So LZMA2 won't
+    provide more output anymore, but it won't know it
+    yet and thus won't return LZMA_STREAM_END yet.
+
+  - A BCJ filter is in use and it hasn't left any
+    unfiltered bytes in the temp buffer. This can happen
+    with any BCJ filter, but in practice it's more likely
+    with filters other than the x86 BCJ.
+
+Another situation where the bug can be triggered happens
+if the uncompressed size is zero bytes and no output space
+is provided. In this case the decompression can fail even
+if the whole input file is given to lzma_code().
+
+A similar bug was fixed in XZ Embedded on 2011-09-19.

+The decoder considered empty LZMA2 streams to be corrupt.
+This shouldn't matter much with .xz files, because no encoder
+creates empty LZMA2 streams in .xz. This bug is more likely
+to cause problems in applications that use raw LZMA2 streams.

+
+The biggest problem was that the integrity check type
+wasn't validated, and e.g. lzma_easy_buffer_encode()
+would create a corrupt .xz Stream if given an unsupported
+Check ID. Luckily applications don't usually try to use
+an unsupport Check ID, so this bug is unlikely to cause
+many real-world problems.

+Empty Block wastes a few bytes of space, but more importantly
+it triggers a bug in XZ Utils 5.0.1 and older when trying
+to decompress such a file. 5.0.1 and older consider such
+files to be corrupt. I thought that no encoder creates empty
+Blocks when releasing 5.0.2 but I was wrong.

+Subject: Fix exit status of "xzdiff foo.xz bar.xz".
+
+xzdiff was clobbering the exit status from diff in a case
+statement used to analyze the exit statuses from "xz" when
+its operands were two compressed files. Save and restore
+diff's exit status to fix this.
+
+The bug is inherited from zdiff in GNU gzip and was fixed
+there on 2009-10-09.
+
+Thanks to Jonathan Nieder for the patch and
+to Peter Pallinger for reporting the bug.

+Subject: Fix exit status of xzgrep when grepping binary files.
+
+When grepping binary files, grep may exit before it has
+read all the input. In this case, gzip -q returns 2 (eating
+SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status
+(e.g. 141). This causes wrong exit status when grepping
+xz- or bzip2-compressed binary files.
+
+The fix checks for the special exit status that indicates SIGPIPE.
+It uses kill -l which should be supported everywhere since it
+is in both SUSv2 (1997) and POSIX.1-2008.
+
+Thanks to James Buren for the bug report.

+  The tiny xzdec and lzmadec decompressors have been moved to the new

+xz-utils (4.999.9beta+20100117-1) unstable; urgency=low
+
+  From this version on, xz produces sparse files by default when
+  decompressing.  This saves disk space when reproducing files with long
+  runs of zero bytes, such as file system images.  Implementing this
+  feature requires seeking forward beyond the end of a file so that the
+  operating system knows where to put in a hole.
+
+  If you use xz --decompress to write to end of a file that is appended
+  to at the same time by another process, this could cause concurrent
+  output from the other command to be overwritten.  This is a rare and
+  quite weird thing to do.  If you really want to do it, note that xz’s
+  buffering strategy is not part of its documented interface; to safely
+  interleave concurrent output from xz and another command, a
+  construction such as
+
+  	xz --decompress input.xz | dd ibs=1k obs=1k >> log
+
+  would be needed to avoid unpredictable results.

+XZ Utils for Debian
+===================
+
+Contents:
+ 1. Differences from standard XZ Utils
+ 2. History
+ 3. LZMA Utils compatibility
+ 4. Configuration
+
+Differences from standard XZ Utils
+----------------------------------
+
+ * The soname of standard liblzma was bumped to 5.0.0, while Debian
+   liblzma remains at 2.0.0.
+
+ * Some corners of the liblzma API (like layout of reserved fields)
+   have therefore been maintained at an older version in Debian
+   liblzma.  Pre-compiled applications built against liblzma on
+   other distributions are likely not to work on this version of
+   Debian if an additional compatibility library is not installed.
+
+See /usr/share/doc/liblzma2/README.Debian for details.
+
+History
+-------
+
+XZ Utils should have been called LZMA Utils 4.42, but it came too late.
+The old .lzma file format has some problems, worst of which is the lack
+of magic number, but it gets enough use to still need to be supported.
+See /usr/share/doc/xz-utils/history.txt.gz for the full story.
+
+LZMA Utils compatibility
+------------------------
+
+To support old scripts and muscle memory, XZ Utils can emulate the
+legacy LZMA Utils interface.  To use this feature, you can install some
+subset of the following list of symbolic links to your $PATH.
+
+	lzma, unlzma, lzcat -> /usr/bin/xz
+	lzgrep, lzegrep, lzfgrep -> /usr/bin/xzgrep
+	lzless -> /usr/bin/xzless
+	lzmore -> /usr/bin/xzmore
+	lzdiff, lzcmp -> /usr/bin/xzdiff
+
+To allow administrators to keep the old lzma package, the xz-utils
+package does not provide those links itself.  If you would like XZ Utils
+to provide these commands by default for all users, install the
+xz-lzma package.
+
+Configuration
+-------------
+
+The memory usage of xz can vary from a few hundred kilobytes to several
+gigabytes depending on the compression settings.  If you would like xz
+to automatically scale down its settings while compressing to decrease
+memory usage, you can declare so by adding an option like the
+following to your environment (e.g., in ~/.profile):
+
+	XZ_DEFAULTS=--memlimit-compress=256MiB
+	export XZ_DEFAULTS
+
+See the "Memory usage" section of the xz(1) manual page for details.
