|

|

bzip2/libbzip2 version 1.0.6 of 6 September 2010
|
||||
Copyright (C) 1996-2010 Julian Seward <jseward@bzip.org>
|
||||

||||

|

------------------------------------------------------------------
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
1.0.6 (2010-09-23)
|
||||
------------------
|
||||
|
||||
* Stripped down by g10 Code GmbH. Tarball renamed to bzip2-1.0.6-g10.tar.gz
|
||||
|
||||
|
||||
1.0.6 (2012-01-13)
|
||||
------------------
|
||||
|
||||
* New Makefile and included into the GnuPG 1.4 source.

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.
|
||||

I hope you find bzip2 useful. Feel free to contact me at
|
||||
jseward@bzip.org
|
||||
if you have any suggestions or queries. Many people mailed me with
|
||||
comments, suggestions and patches after the releases of bzip-0.15,
|
||||
bzip-0.21, and bzip2 versions 0.1pl2, 0.9.0, 0.9.5, 1.0.0, 1.0.1,
|
||||
1.0.2 and 1.0.3, and the changes in bzip2 are largely a result of this
|
||||
feedback. I thank you for your comments.

This is a stripped down version of bzip2 - version 1.0.6.
|
||||
|
||||
It does not include any drivers but merely builds the libbz2.a
|
||||
library. The source has been taken from www.bzip.org on 2010-09-23
|
||||
and stripped down by g10 Code GmbH for use with Gpg4win and to be
|
||||
included into the GnupG 1.4.12 source.
|
||||
|
||||
The only changed files are Makefile and bzlib.h (disabled Windows
|
||||
specific code).

The source is distributed as a BZIP2 or GZIP compressed tar archive.
|
||||
See the instructions in file README on how to check the integrity of
|
||||
that file. Wir a properly setup build environment, you unpack the
|
||||
that file. With a properly setup build environment, you unpack the
|
||||
tarball change to the created directory and run
|
||||
|
||||
$ ./autogen.sh --build-w32
|
||||
$ make
|
||||
$ cp g10/gpg*.exe /some_windows_drive/
|
||||
|
||||
Building a version with the installer is a bit more complex and
|
||||
basically works by creating a top directory, unpacking in that top
|
||||
directory, switching to the gnupg-1.x.y directory, running
|
||||
"./autogen.sh --build-w32" and "make", switching back to the top
|
||||
directory, running a "mkdir dist-w32; mkdir iconv", copying the
|
||||
required iconv files (iconv.dll, README.iconv, COPYING.LIB) into the
|
||||
iconv directory, running gnupg-1.x.y/scripts/mk-w32-dist and voila,
|
||||
the installer package will be available in the dist-w32 directory.
|
||||
Building a version with the installer requires an install NSIS tool
|
||||
and a directory with the iconv files. The script mk-w32-dist does the
|
||||
entire build from the tarball and checks most prerequisites; example:
|
||||
|
||||
$ scripts/mk-w32-dist $(pwd)/gnupg-1.4.3.tar.gz
|
||||
|
||||
If you installed the iconv files in a non-standard place you may use
|
||||
|
||||
$ scripts/mk-w32-dist --iconv-dir /foo/bar/ $(pwd)/gnupg-1.4.3.tar.gz
|
||||
|
||||
If you need to patch the standard tarball, you can supply a patch file:
|
||||
|
||||
$ scripts/mk-w32-dist $(pwd)/gnupg-1.4.3.tar.gz mypatches
|
||||
|
||||
That patch file will then be part of the installer.
