-0.9.0
-~~~~~
-First version.
-
-
-0.9.0a
-~~~~~~
-Removed 'ranlib' from Makefile, since most modern Unix-es
-don't need it, or even know about it.
-
-
-0.9.0b
-~~~~~~
-Fixed a problem with error reporting in bzip2.c. This does not effect
-the library in any way. Problem is: versions 0.9.0 and 0.9.0a (of the
-program proper) compress and decompress correctly, but give misleading
-error messages (internal panics) when an I/O error occurs, instead of
-reporting the problem correctly. This shouldn't give any data loss
-(as far as I can see), but is confusing.
-
-Made the inline declarations disappear for non-GCC compilers.
-
-
-0.9.0c
-~~~~~~
-Fixed some problems in the library pertaining to some boundary cases.
-This makes the library behave more correctly in those situations. The
-fixes apply only to features (calls and parameters) not used by
-bzip2.c, so the non-fixedness of them in previous versions has no
-effect on reliability of bzip2.c.
-
-In bzlib.c:
- * made zero-length BZ_FLUSH work correctly in bzCompress().
- * fixed bzWrite/bzRead to ignore zero-length requests.
- * fixed bzread to correctly handle read requests after EOF.
- * wrong parameter order in call to bzDecompressInit in
- bzBuffToBuffDecompress. Fixed.
-
-In compress.c:
- * changed setting of nGroups in sendMTFValues() so as to
- do a bit better on small files. This _does_ effect
- bzip2.c.
-
-
-0.9.5a
-~~~~~~
-Major change: add a fallback sorting algorithm (blocksort.c)
-to give reasonable behaviour even for very repetitive inputs.
-Nuked --repetitive-best and --repetitive-fast since they are
-no longer useful.
-
-Minor changes: mostly a whole bunch of small changes/
-bugfixes in the driver (bzip2.c). Changes pertaining to the
-user interface are:
-
- allow decompression of symlink'd files to stdout
- decompress/test files even without .bz2 extension
- give more accurate error messages for I/O errors
- when compressing/decompressing to stdout, don't catch control-C
- read flags from BZIP2 and BZIP environment variables
- decline to break hard links to a file unless forced with -f
- allow -c flag even with no filenames
- preserve file ownerships as far as possible
- make -s -1 give the expected block size (100k)
- add a flag -q --quiet to suppress nonessential warnings
- stop decoding flags after --, so files beginning in - can be handled
- resolved inconsistent naming: bzcat or bz2cat ?
- bzip2 --help now returns 0
-
-Programming-level changes are:
-
- fixed syntax error in GET_LL4 for Borland C++ 5.02
- let bzBuffToBuffDecompress return BZ_DATA_ERROR{_MAGIC}
- fix overshoot of mode-string end in bzopen_or_bzdopen
- wrapped bzlib.h in #ifdef __cplusplus ... extern "C" { ... }
- close file handles under all error conditions
- added minor mods so it compiles with DJGPP out of the box
- fixed Makefile so it doesn't give problems with BSD make
- fix uninitialised memory reads in dlltest.c
-
-0.9.5b
-~~~~~~
-Open stdin/stdout in binary mode for DJGPP.
-
-0.9.5c
-~~~~~~
-Changed BZ_N_OVERSHOOT to be ... + 2 instead of ... + 1. The + 1
-version could cause the sorted order to be wrong in some extremely
-obscure cases. Also changed setting of quadrant in blocksort.c.
-
-0.9.5d
-~~~~~~
-The only functional change is to make bzlibVersion() in the library
-return the correct string. This has no effect whatsoever on the
-functioning of the bzip2 program or library. Added a couple of casts
-so the library compiles without warnings at level 3 in MS Visual
-Studio 6.0. Included a Y2K statement in the file Y2K_INFO. All other
-changes are minor documentation changes.
-
-1.0
-~~~
-Several minor bugfixes and enhancements:
-
-* Large file support. The library uses 64-bit counters to
- count the volume of data passing through it. bzip2.c
- is now compiled with -D_FILE_OFFSET_BITS=64 to get large
- file support from the C library. -v correctly prints out
- file sizes greater than 4 gigabytes. All these changes have
- been made without assuming a 64-bit platform or a C compiler
- which supports 64-bit ints, so, except for the C library
- aspect, they are fully portable.
-
-* Decompression robustness. The library/program should be
- robust to any corruption of compressed data, detecting and
- handling _all_ corruption, instead of merely relying on
- the CRCs. What this means is that the program should
- never crash, given corrupted data, and the library should
- always return BZ_DATA_ERROR.
-
-* Fixed an obscure race-condition bug only ever observed on
- Solaris, in which, if you were very unlucky and issued
- control-C at exactly the wrong time, both input and output
- files would be deleted.
-
-* Don't run out of file handles on test/decompression when
- large numbers of files have invalid magic numbers.
-
-* Avoid library namespace pollution. Prefix all exported
- symbols with BZ2_.
-
-* Minor sorting enhancements from my DCC2000 paper.
-
-* Advance the version number to 1.0, so as to counteract the
- (false-in-this-case) impression some people have that programs
- with version numbers less than 1.0 are in some way, experimental,
- pre-release versions.
-
-* Create an initial Makefile-libbz2_so to build a shared library.
- Yes, I know I should really use libtool et al ...
-
-* Make the program exit with 2 instead of 0 when decompression
- fails due to a bad magic number (ie, an invalid bzip2 header).
- Also exit with 1 (as the manual claims :-) whenever a diagnostic
- message would have been printed AND the corresponding operation
- is aborted, for example
- bzip2: Output file xx already exists.
- When a diagnostic message is printed but the operation is not
- aborted, for example
- bzip2: Can't guess original name for wurble -- using wurble.out
- then the exit value 0 is returned, unless some other problem is
- also detected.
-
- I think it corresponds more closely to what the manual claims now.
-
-
-1.0.1
-~~~~~
-* Modified dlltest.c so it uses the new BZ2_ naming scheme.
-* Modified makefile-msc to fix minor build probs on Win2k.
-* Updated README.COMPILATION.PROBLEMS.
-
-There are no functionality changes or bug fixes relative to version
-1.0.0. This is just a documentation update + a fix for minor Win32
-build problems. For almost everyone, upgrading from 1.0.0 to 1.0.1 is
-utterly pointless. Don't bother.
-
-
-1.0.2
-~~~~~
-A bug fix release, addressing various minor issues which have appeared
-in the 18 or so months since 1.0.1 was released. Most of the fixes
-are to do with file-handling or documentation bugs. To the best of my
-knowledge, there have been no data-loss-causing bugs reported in the
-compression/decompression engine of 1.0.0 or 1.0.1.
-
-Note that this release does not improve the rather crude build system
-for Unix platforms. The general plan here is to autoconfiscate/
-libtoolise 1.0.2 soon after release, and release the result as 1.1.0
-or perhaps 1.2.0. That, however, is still just a plan at this point.
-
-Here are the changes in 1.0.2. Bug-reporters and/or patch-senders in
-parentheses.
-
-* Fix an infinite segfault loop in 1.0.1 when a directory is
- encountered in -f (force) mode.
- (Trond Eivind Glomsrod, Nicholas Nethercote, Volker Schmidt)
-
-* Avoid double fclose() of output file on certain I/O error paths.
- (Solar Designer)
-
-* Don't fail with internal error 1007 when fed a long stream (> 48MB)
- of byte 251. Also print useful message suggesting that 1007s may be
- caused by bad memory.
- (noticed by Juan Pedro Vallejo, fixed by me)
-
-* Fix uninitialised variable silly bug in demo prog dlltest.c.
- (Jorj Bauer)
-
-* Remove 512-MB limitation on recovered file size for bzip2recover
- on selected platforms which support 64-bit ints. At the moment
- all GCC supported platforms, and Win32.
- (me, Alson van der Meulen)
-
-* Hard-code header byte values, to give correct operation on platforms
- using EBCDIC as their native character set (IBM's OS/390).
- (Leland Lucius)
-
-* Copy file access times correctly.
- (Marty Leisner)
-
-* Add distclean and check targets to Makefile.
- (Michael Carmack)
-
-* Parameterise use of ar and ranlib in Makefile. Also add $(LDFLAGS).
- (Rich Ireland, Bo Thorsen)
-
-* Pass -p (create parent dirs as needed) to mkdir during make install.
- (Jeremy Fusco)
-
-* Dereference symlinks when copying file permissions in -f mode.
- (Volker Schmidt)
-
-* Majorly simplify implementation of uInt64_qrm10.
- (Bo Lindbergh)
-
-* Check the input file still exists before deleting the output one,
- when aborting in cleanUpAndFail().
- (Joerg Prante, Robert Linden, Matthias Krings)
-
-Also a bunch of patches courtesy of Philippe Troin, the Debian maintainer
-of bzip2:
-
-* Wrapper scripts (with manpages): bzdiff, bzgrep, bzmore.
-
-* Spelling changes and minor enhancements in bzip2.1.
-
-* Avoid race condition between creating the output file and setting its
- interim permissions safely, by using fopen_output_safely().
- No changes to bzip2recover since there is no issue with file
- permissions there.
-
-* do not print senseless report with -v when compressing an empty
- file.
-
-* bzcat -f works on non-bzip2 files.
-
-* do not try to escape shell meta-characters on unix (the shell takes
- care of these).
-
-* added --fast and --best aliases for -1 -9 for gzip compatibility.
-
-
-1.0.3 (15 Feb 05)
-~~~~~~~~~~~~~~~~~
-Fixes some minor bugs since the last version, 1.0.2.
-
-* Further robustification against corrupted compressed data.
- There are currently no known bitstreams which can cause the
- decompressor to crash, loop or access memory which does not
- belong to it. If you are using bzip2 or the library to
- decompress bitstreams from untrusted sources, an upgrade
- to 1.0.3 is recommended. This fixes CAN-2005-1260.
-
-* The documentation has been converted to XML, from which html
- and pdf can be derived.
-
-* Various minor bugs in the documentation have been fixed.
-
-* Fixes for various compilation warnings with newer versions of
- gcc, and on 64-bit platforms.
-
-* The BZ_NO_STDIO cpp symbol was not properly observed in 1.0.2.
- This has been fixed.
-
-
-1.0.4 (20 Dec 06)
-~~~~~~~~~~~~~~~~~
-Fixes some minor bugs since the last version, 1.0.3.
-
-* Fix file permissions race problem (CAN-2005-0953).
-
-* Avoid possible segfault in BZ2_bzclose. From Coverity's NetBSD
- scan.
-
-* 'const'/prototype cleanups in the C code.
-
-* Change default install location to /usr/local, and handle multiple
- 'make install's without error.
-
-* Sanitise file names more carefully in bzgrep. Fixes CAN-2005-0758
- to the extent that applies to bzgrep.
-
-* Use 'mktemp' rather than 'tempfile' in bzdiff.
-
-* Tighten up a couple of assertions in blocksort.c following automated
- analysis.
-
-* Fix minor doc/comment bugs.
-
-
-1.0.5 (10 Dec 07)
-~~~~~~~~~~~~~~~~~
-Security fix only. Fixes CERT-FI 20469 as it applies to bzip2.
-
-
-1.0.6 (6 Sept 10)
-~~~~~~~~~~~~~~~~~
-
-* Security fix for CVE-2010-0405. This was reported by Mikolaj
- Izdebski.
-
-* Make the documentation build on Ubuntu 10.04
