opened (e.g. read-only) (bug #717852)
- Implemented --ignore-trailing-garbage feature (bug #594868)
- Fixed hang on decompress of some truncated archives (bug #590225)
- Pulled an error check out of normal logic block for clarity
- Debug print added after BZ2_bzDecompress to track it's return code.
- A debug print fixed in queue::remove
- Increased max memory usage limit from 1GB to 2GB
- If no -m switch given on command line, default max memory limit
will now automatically increase from 100 MB to minimum amount
of memory required to support the number of CPUs requested
- Improved performance when output buffer is full
- Fixed bug which caused hang while decompressing prematurely
truncated bzip2 stream
- Consumer_decompress throttling modified to prevent potential
deadlock/infinite loop in certain situations (Thanks to Laszlo
Ersek for finding and helping track down the cause of this bug)
- Fixed deadlock bug and performance issue when consumer working
with long bzip2 sequences (Thanks to Tanguy Fautre for finding)
- Fixed error message for block size range (max size was wrong)
- Moved #include <pthread.h> from pbzip2.cpp to pbzip2.h to fix
OS/2 compiler issue
Changes in 1.1.1 (Apr 17, 2010)
- Modified decompression to use low-level libbz2 API to improve
performance of long bzip2 streams of large single-stream bzip2
blocks
- This release should now decompress files created with bzip2
at least as fast as bzip2 or slightly faster
- Handle decompression of long bzip2 streams incrementally
instead of loading whole stream in memory at once
- Fixed issue in safe_cond_timed_wait which caused segmentation
fault when compiled in DEBUG mode
- Fixed issue with Sun Studio compiler - required explicit
declaration of static const members in .cpp
Changes in 1.1.0 (Mar 13, 2010)
- Added support for multi-threaded decompression using STDIN/pipes
- Added code to support throttling compression to prevent memory
exhaustion with slow output pipe
- Added -m switch to specify max memory usage amount before
throttling starts (default 100MB)
- Fixed bug that did not allow command line parameters to be used
when compressing data from STDIN
- Added long options to man page and -h output
- Added --loadavg, --read long options
- Added support for CPU detection on Win32
- Major improvements to protection of shared variables, error and
signal handling, program termination
- Added -S switch for thread stack size customization
(needs USE_STACKSIZE_CUSTOMIZATION defined when compiling)
- Fixed command line parsing bug for -b, -p, -m switches
- Fixed infinite loop when fileWriter fails to create output
file at start
- Fixed bug that deleted input filename (with .bz2 extension for
compression and without .bz2 extension for decompression) when
a user interrupts process with CTRL-C while outputting to STDOUT
- Fixed bug where 0 byte files were not processed properly when
data input from STDIN
- Ignores fwrite return and passes chown errors in writeFileMetaData
if effective uid root
- OutputBuffer usage redesigned as fixed-size circular buffer
- Lots of minor bugs fixed (see AUTHORS or pbzip2.cpp for full details)
- Special thanks to Yavor Nikolov for providing the majority of
contributions to this release and a significant amount of testing
Changes in 0.9.4 (Aug 30, 2005)

created with a BWT block size other than default 900k (oops!)
- Fixed some bugs in the command line parser
- Code cleanup
- Updated RPM spec to match Fedora Extras policy
Changes in 0.9.3 (Aug 22, 2005)
- Added sanity check to ensure integers are the size we expect
- Ported code to compile under MinGW in Windows
- Small code cleanup
- Added ChangeLog
- Added man page
- Added AUTHORS file
- Renamed LICENCE.txt to COPYING
- Renamed README.txt to README
- Updated RPM spec file in preparation for inclusion into Fedora Extras
- Moved ChangeLog info from pbzip2.cpp into this file
- Removed extra spaces/tabs in pbzip2.cpp
The pbzip2 program is a parallel version of bzip2 for use on shared
memory machines. It provides near-linear speedup when used on true
multi-processor machines and 5-10% speedup on Hyperthreaded machines.
The output is fully compatible with the regular bzip2 data so any
files created with pbzip2 can be uncompressed by bzip2 and vice-versa.
