Changelog
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.
