| Name: lbzip2 | Distribution: SUSE Linux Enterprise 15 SP4 |
| Version: 2.5 | Vendor: openSUSE |
| Release: bp154.2.20 | Build date: Mon May 9 18:55:46 2022 |
| Group: Productivity/Archiving/Compression | Build host: s390zl28 |
| Size: 221223 | Source RPM: lbzip2-2.5-bp154.2.20.src.rpm |
| Packager: https://bugs.opensuse.org | |
| Url: https://github.com/kjn/lbzip2 | |
| Summary: Parallel bzip2/bunzip2 Filter | |
Lbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to GNU tar with the --use-compress-program option. It isn't restricted to regular files on input, nor output. Successful splitting for decompression isn't guaranteed, just very likely (failure is detected). Splitting in both modes and compression itself occur with an approximate 900k block size. On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2 when compressing, and 45% faster when decompressing (based on wall clock time). Lbzip2 strives to be portable by requiring UNIX 98 APIs only, besides an unmodified libbz2.

* Wed Apr 28 2021 psychonaut@nothingisreal.com
- Update project URL in spec file; the previously official domain
lbzip2.org has seemingly lapsed and been taken over by an impostor
* Sat Jun 15 2019 psychonaut@nothingisreal.com
- Replace source tarball with one using the latest version of gnulib;
this works around the build failure caused by incompatible updates
to glibc 2.28. For further details see
<https://github.com/kjn/lbzip2/issues/22> and
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=915171>. Note
that it was not possible to (cleanly) provide a patchfile due to the
peculiar way in which the lbzip2 source distribution is
bootstrapped; the bootstrap script pulls in the gnulib source, runs
some code generation scripts, and then calls the Autotools toolchain
on the result. Since the Autotools input and output files end up
getting modified by the patch, the build process fails because it
thinks the generated versions are out of date.

- Modernise spec file with spec-cleaner
* Sun Apr 12 2015 mpluskal@suse.com
- Cleanup spec file with spec-cleaner
- Cleanup dependencies
* Thu Apr 10 2014 idonmez@suse.com
- Update to version 2.5
* Performance improvements.
* Fixed a decompression bug in bz2 header parsing code.
* Fixed an assertion failure bug that could cause core dumps when
compressing some kind of data.
* Fixed a bug which prevented symbolic links to be opened in some
situations.
* Fixed a bug that caused SIGXFSZ to be handled incorrectly on 32-bit
systems.
* Mon Aug 20 2012 pascal.bleser@opensuse.org
- update to 2.2:
* decompressor was made more bzip2-compatible: all valid bzip2 files should
now be properly decompressed by lbzip2
* memory allocation was reduced significantly: previous versions could
allocate large amounts of memory during decompression and testing of highly
compressed files
* fixes a bug that caused some legitimate bz2 files to be rejected during
decompression with a CRC error message
* compression performance is increased significantly by inclusion of new
block-sorting code using divsufsort algorithm
* file write errors caused by broken pipes or exceeded file size limits are
no longer reported to standard error
* Thu Nov 24 2011 pascal.bleser@opensuse.org
- license changes from GPL v2+ to GPL v3.0
- update to 2.1:
* fixes a use-after-free security vulnerability in decompressor code
responsible for displaying progress information
- changes from 2.0:
* now lbzip2 creates one compressed stream per bzip2 file instead of multiple
concatenated streams
* lbzip2 now doesn't decompress streams embedded within trailing garbage
after initial sequence of streams
* now lbzip2 detects and rejects more kinds of invalid bzip2 files (files
with invalid stream CRCs, files with blocks larger than stated in stream
headers and some others)
* both compression and decompression speed is increased significantly
* when invoked with `-v' or `--verbose' options lbzip2 now displays
information about progress of compression or decompression, provided that
stderr is connected to a terminal
* when invoked with `-v' or `--verbose' options lbzip2 now displays
compression ratio and space savings for each compressed or decompressed
file
* lbzip2 now supports `--exponential' option with the same semantics as
bzip2's one
* now lbzip2 displays more detailed messages on decompression failure
* help and version information is now printed to standard output instead of
standard error stream
* abandoned support for tracing memory allocation by setting the
environmental variable `LBZIP2_TRACE_ALLOC', was dropped
* Wed Mar 03 2010 pascal.bleser@opensuse.org
- update to 0.23:
* if lbzip2 intends to exit with status 1 due to any fatal error,
but any SIGPIPE or SIGXFSZ with an inherited SIG_DFL action was
generated for lbzip2 previously, then lbzip2 terminates by way
of one of the said signals, after cleaning up any interrupted
output file; this should improve compatibility with GNU tar
when it spawns lbzip2 as a filter and closes the pipe between
them early, before it receives an EOF from lbzip2
* Thu Feb 18 2010 pascal.bleser@opensuse.org
- update to 0.21:
* fixes a race condition
* Mon Dec 28 2009 pascal.bleser@opensuse.org
- update to 0.20:
* portability fixes
