+
+
+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

+PDF (manual.pdf) or html (manual.html). A plain-text version of the
+manual page is available as bzip2.txt.
+
+
+HOW TO BUILD -- UNIX
+
+Type 'make'. This builds the library libbz2.a and then the programs
+bzip2 and bzip2recover. Six self-tests are run. If the self-tests
+complete ok, carry on to installation:
+
+To install in /usr/local/bin, /usr/local/lib, /usr/local/man and
+/usr/local/include, type
+
+ make install
+
+To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type
+
+ make install PREFIX=/xxx/yyy
+
+If you are (justifiably) paranoid and want to see what 'make install'
+is going to do, you can first do
+
+ make -n install or
+ make -n install PREFIX=/xxx/yyy respectively.
+
+The -n instructs make to show the commands it would execute, but not
+actually execute them.
+
+
+HOW TO BUILD -- UNIX, shared library libbz2.so.
+
+Do 'make -f Makefile-libbz2_so'. This Makefile seems to work for
+Linux-ELF (RedHat 7.2 on an x86 box), with gcc. I make no claims
+that it works for any other platform, though I suspect it probably
+will work for most platforms employing both ELF and gcc.
+
+bzip2-shared, a client of the shared library, is also built, but not
+self-tested. So I suggest you also build using the normal Makefile,
+since that conducts a self-test. A second reason to prefer the
+version statically linked to the library is that, on x86 platforms,
+building shared objects makes a valuable register (%ebx) unavailable
+to gcc, resulting in a slowdown of 10%-20%, at least for bzip2.
+
+Important note for people upgrading .so's from 0.9.0/0.9.5 to version
+1.0.X. All the functions in the library have been renamed, from (eg)
+bzCompress to BZ2_bzCompress, to avoid namespace pollution.
+Unfortunately this means that the libbz2.so created by
+Makefile-libbz2_so will not work with any program which used an older
+version of the library. I do encourage library clients to make the
+effort to upgrade to use version 1.0, since it is both faster and more
+robust than previous versions.
+
+
+HOW TO BUILD -- Windows 95, NT, DOS, Mac, etc.
+
+It's difficult for me to support compilation on all these platforms.
+My approach is to collect binaries for these platforms, and put them
+on the master web site (http://www.bzip.org). Look there. However
+(FWIW), bzip2-1.0.X is very standard ANSI C and should compile
+unmodified with MS Visual C. If you have difficulties building, you
+might want to read README.COMPILATION.PROBLEMS.
+
+At least using MS Visual C++ 6, you can build from the unmodified
+sources by issuing, in a command shell:
+
+ nmake -f makefile.msc
+
+(you may need to first run the MSVC-provided script VCVARS32.BAT
+ so as to set up paths to the MSVC tools correctly).
+
+
+VALIDATION
+
+Correct operation, in the sense that a compressed file can always be
+decompressed to reproduce the original, is obviously of paramount
+importance. To validate bzip2, I used a modified version of Mark
+Nelson's churn program. Churn is an automated test driver which
+recursively traverses a directory structure, using bzip2 to compress
+and then decompress each file it encounters, and checking that the
+decompressed data is the same as the original.
+
+
+
+Please read and be aware of the following:
+
+WARNING:
+
+ This program and library (attempts to) compress data by
+ performing several non-trivial transformations on it.
+ Unless you are 100% familiar with *all* the algorithms
+ contained herein, and with the consequences of modifying them,
+ you should NOT meddle with the compression or decompression
+ machinery. Incorrect changes can and very likely *will*
+ lead to disastrous loss of data.
+
+
+DISCLAIMER:
+
+ I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
+ USE OF THIS PROGRAM/LIBRARY, HOWSOEVER CAUSED.
+
+ Every compression of a file implies an assumption that the
+ compressed file can be decompressed to reproduce the original.
+ Great efforts in design, coding and testing have been made to
+ ensure that this program works correctly. However, the complexity
+ of the algorithms, and, in particular, the presence of various
+ special cases in the code which occur with very low but non-zero
+ probability make it impossible to rule out the possibility of bugs
+ remaining in the program. DO NOT COMPRESS ANY DATA WITH THIS
+ PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE POSSIBILITY, HOWEVER
+ SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
+
+ That is not to say this program is inherently unreliable.
+ Indeed, I very much hope the opposite is true. bzip2/libbzip2
+ has been carefully constructed and extensively tested.
+
+
+PATENTS:
+
+ To the best of my knowledge, bzip2/libbzip2 does not use any
+ patented algorithms. However, I do not have the resources
+ to carry out a patent search. Therefore I cannot give any
+ guarantee of the above statement.
+
+
+
+WHAT'S NEW IN 0.9.0 (as compared to 0.1pl2) ?
+
+ * Approx 10% faster compression, 30% faster decompression
+ * -t (test mode) is a lot quicker
+ * Can decompress concatenated compressed files
+ * Programming interface, so programs can directly read/write .bz2 files
+ * Less restrictive (BSD-style) licensing
+ * Flag handling more compatible with GNU gzip
+ * Much more documentation, i.e., a proper user manual
+ * Hopefully, improved portability (at least of the library)
+
+WHAT'S NEW IN 0.9.5 ?
+
+ * Compression speed is much less sensitive to the input
+ data than in previous versions. Specifically, the very
+ slow performance caused by repetitive data is fixed.
+ * Many small improvements in file and flag handling.
+ * A Y2K statement.
+

+ See the CHANGES file.

+
+bzip2-1.0.6 should compile without problems on the vast majority of
+platforms. Using the supplied Makefile, I've built and tested it
+myself for x86-linux and amd64-linux. With makefile.msc, Visual C++
+6.0 and nmake, you can build a native Win32 version too. Large file
+support seems to work correctly on at least on amd64-linux.
+
+When I say "large file" I mean a file of size 2,147,483,648 (2^31)
+bytes or above. Many older OSs can't handle files above this size,
+but many newer ones can. Large files are pretty huge -- most files
+you'll encounter are not Large Files.
+
+Early versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety
+of platforms without difficulty, and I hope this version will continue
+in that tradition. However, in order to support large files, I've had
+to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This
+can cause problems.
+
+The technique of adding -D_FILE_OFFSET_BITS=64 to get large file
+support is, as far as I know, the Recommended Way to get correct large
+file support. For more details, see the Large File Support
+Specification, published by the Large File Summit, at
+
+ http://ftp.sas.com/standards/large.file
+
+As a general comment, if you get compilation errors which you think
+are related to large file support, try removing the above define from
+the Makefile, ie, delete the line
+
+ BIGFILES=-D_FILE_OFFSET_BITS=64
+
+from the Makefile, and do 'make clean ; make'. This will give you a
+version of bzip2 without large file support, which, for most
+applications, is probably not a problem.
+
+Alternatively, try some of the platform-specific hints listed below.
+
+You can use the spewG.c program to generate huge files to test bzip2's
+large file support, if you are feeling paranoid. Be aware though that
+any compilation problems which affect bzip2 will also affect spewG.c,
+alas.
+
+AIX: I have reports that for large file support, you need to specify
+-D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested
+this myself.
