msys bzip2 =============================================================================== bzip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression. Release: bzip2-1.0.6-1-msys-1.0.17 Files: bzip2-1.0.6-1-msys-1.0.17-src.tar.lzma (full source code) bzip2-1.0.6-1-msys-1.0.17-bin.tar.lzma (utilities) bzip2-1.0.6-1-msys-1.0.17-doc.tar.lzma (FAQ, readmes, manpages) bzip2-1.0.6-1-msys-1.0.17-lic.tar.lzma (licensing terms) libbz2-1.0.6-1-msys-1.0.17-dev.tar.lzma (libraries and headers) libbz2-1.0.6-1-msys-1.0.17-dll-1.tar.lzma (redistributable DLL) Notes: This is a binary release of the bzip2 compression/decompression library, compiled for use with MSYS applications. The source code is modified from that distributed by bzip.org, to fix various security holes, correct build errors, and add new features. In addition, the original build system has been completely replaced by an autoconf-based one (see README.CYGMING for more information). The "src" tarball delivers the full unmodified source code from bzip.org, along with the relevant patches and (external) build driver (.mgwport) script. The "doc", "lic" and "man" tarballs provide the documentation components, as identified above, abstracted from the source tarball, and repackaged into a file hierarchy structure which is suitable for installation into the user's installed MSYS directory hierarchy; for a standard installation, they should be unpacked into the C:\MinGW\msys\1.0 directory. The "bin" tarball provides the bzip2.exe compression utility, along with several other utilities and scripts. This package should be unpacked into the C:\MinGW\msys\1.0 directory. Developers of MSYS applications, who wish to link to the bzip2 libraries, will require at least the "dev" tarball; this provides the libbz2.a static version of the library, libbz2.dll.a import library, for linking to a DLL version of the library, and the set of C language headers common to both. The DLL version of the library, msys-bz2-1.dll, is provided separately, by the "dll-1" tarball. As in the case of the installable documentation, each of these tarballs should be unpacked into the C:\MinGW\msys\1.0 directory. Please note that the msys-bz2-1.dll delivered by this package depends on the MSYS runtime msys-1.0.dll. Developers need to install and use the msys-system-builder (aka msys-dvlpr) toolkit to compile clients of this library; it may NOT be used in conjunction with the MinGW compiler (which generates native win32 binaries, rather than MSYS-dependent ones).

No history is maintained here. All currently enabled tests have passed. =============================================================================== Port Notes: 1) This msys build of bzip2 DOES NOT support 64 bit file access (large files), because the msys runtime does not support 64bit off_t. 2) This build is based on the cygwin source patches, NOT any MinGW ones. It is only "lightly" ported -- that is, the sources have not been modified to recognize #define __MSYS__. Therefore, when compiling against this library, you should explicitly define the __CYGWIN__ macro, by adding -D__CYGWIN__ to your CFLAGS (msys-gcc-3.4.4-3 does this automatically). 3) (internal:) the original, and rather dated and inflexible, build system has been completely replaced by a new autoconf-based one, contributed by Keith Marshall. This allows for (a) out-of-tree builds, (b) cross- compiler builds, and (c) better handling for win32/cygwin builds. However, this original contribution required some additional tweaks, to support MSYS. 4) (internal:) The build and packaging is driven by an external .msysport script, to handle the specifics of package creation and naming suitable for use with the mingw-get installation program. =============================================================================== ---------- bzip2-1.0.6-1 -- 2011 Sep 01 ----------- * Updated to most recent upstream release - fixes CVE-2010-0405 * Add --show-progress option to bzip2 * Update documentation, correct various errors and omissions * Incorporate and adapt Keith's autoconf-based internal build system patches. * Update external build driver system to use mgwport ---------- bzip2-1.0.5-2 -- 2010 Jan 28 ----------- * Rebuild against msys-1.0.13, using (msys)gcc-3.4.4 and (msys)binutils-2.19.51. * Use -O3 -fno-unit-at-a-time to avoid optimization bug in latest msys-gcc. Also, don't use -mms-bitfields when compiling msys binaries. ---------- bzip2-1.0.5-1 -- 2009 Jul 26 ----------- * First release of bzip2 for msys using new packaging standard. * Uses patches derived from cygwin's bzip2-1.0.5-10 package.
