lbzip2 is an independent, multi-threaded implementation of bzip2 which
can process standard bz2 files in parallel. It uses POSIX threading
model (pthreads), which allows it to take full advantage of the symmetric
multiprocessing (SMP) systems. It has been proven to scale linearly, even
to over one hundred processor cores, and commonly considered the fastest
SMP (and uniprocessor) bzip2 compressor and decompressor.
lbzip2 is fully compatible with bzip2 -- both at file format and command
line level. Files created by lbzip2 can be decompressed by all versions
of bzip2 and other software supporting bz2 format. This makes lbzip2 a
drop-in replacement for bzip2.
===> The following configuration options are available for lbzip2-2.5:
DOCS=on: Build and/or install documentation
===> Use 'make config' to modify these settings
archivers/lbzip2: update MASTER_SITES, WWW, and the port description
The project's original domain has been hijacked and it is maintained
on GitHub now. Slightly polish the port description text while here
(particularly, remove needless repetitions), adjust the LICENSE knob
(GPLv3 or later), and drop no longer useful GNU_CONFIGURE_MANPREFIX.

Override GNU_CONFIGURE_MANPREFIX in my GNU autotools-based ports
This is a temporary measure to facilitate entering the new world
order where manual pages are installed under ${PREFIX}/share/man.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
(Only the first 15 lines of the commit message are shown above )
Provide fall-back distfile location while official mastersite is not
accessible, and assume maintainership. This port can be very useful
as PKG_DEPENDS alternative to default packaging method because it is
about twice as fast compared to `archivers/pbzip2', another parallel
BZIP2 compressor we have in the ports.
- Update `archivers/lbzip2' to version 2.5, switch
to the `.tar.bz2' distfile (USES=tar:bzip2)
- Update MASTER_SITES and add LICENSE (GPLv3)
- The build system is GNU autotools-based since 2.x
- Install more complete set of documentation files
- Drop no longer needed WRKSRC, the patch file, and
`do-install' target
- Get rid of the .for loop when installing files on
the PORTDOCS list
When there is a do-install target, do not use a post-install target, do
everything at once. Sometime, rename post-install into a options helper
target.
I did not fix ports that were such a mess that I could not figure out
what they really wanted to do. I also did not change ports that had
some version of an auto-plist code in post-install, for the same reason.

I am here.
- Update 0.23
Version: lbzip2-0.23
Focus: Minor feature enhancements
Date: 03-Mar-2010
Changes: In this release, if lbzip2 intends to exit with status 1 due to any
fatal error, but any SIGPIPE or SIGXFSZ with inherited SIG_DFL action
was generated for lbzip2 previously, then lbzip2 terminates by way of
one of 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.
- Update to 0.22
Version: lbzip2-0.22
Focus: Minor bugfixes
Date: 18-Feb-2010
Changes: Building lbzip2 on Debian unstable discovered that the "lfs.sh" build
script, due to a typo, did not invoke the "getconf" utility in a
SUSv2-conformant way. This bug has been corrected.
Version: lbzip2-0.21
Focus: Minor bugfixes
Date: 17-Feb-2010
Changes: Code examination revealed that lbzip2-0.18 introduced a race between
the following two code paths: (1) the muxer thread displays an error
message when it encounters a write error, (2) the main thread, in
preparation to terminate the process, frees the output file name after
an INT or TERM signal is delivered to it. This bug had negligible
chance to occur, but it was fixed nonetheless.
Feature safe: yes
- Update to 0.19
Version: lbzip2-0.19
Focus: Minor bugfixes
Date: 01-Dec-2009
Changes: This release works around a GNU/kFreeBSD standards-compliance problem.
GNU/kFreeBSD does not define some STREAMS-related errno macros
mandated by SUSv2. Consequently, lbzip2-0.18 cannot be built on
GNU/kFreeBSD. This version checks if those (and some other) macros are
defined before relying them.
Version: lbzip2-0.18
Focus: Major feature enhancements
Date: 29-Nov-2009
Changes: After adding sanity checks to both decompressors, the following
features were implemented: removal of input FILE operands; options
--keep and --force; copying of owner, group, permission bits, access
time, modification time to regular output files. Logging was cleaned
up and internally categorized into INFO, WARNING and FATAL levels; a
separate exit status was introduced for the case when a warning
message was printed. The decompressor robustness tests were
re-executed. The author has finally replaced bzip2 with lbzip2 on his
system.
A multi-threaded bzip2/bunzip2 filter that doesn't depend on the lseek()
system call and so isn't restricted to regular files.
