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
|
||||
|
||||
1.0.7 (27 Jun 19)
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
* Fix undefined behavior in the macros SET_BH, CLEAR_BH, & ISSET_BH
|
||||
|
||||
* bzip2: Fix return value when combining --test,-t and -q.
|
||||
|
||||
* bzip2recover: Fix buffer overflow for large argv[0]
|
||||
|
||||
* bzip2recover: Fix use after free issue with outFile (CVE-2016-3189)
|
||||
|
||||
* Make sure nSelectors is not out of range (CVE-2019-12900)
|
||||
|
||||
1.0.8 (13 Jul 19)
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
* Accept as many selectors as the file format allows.
|
||||
This relaxes the fix for CVE-2019-12900 from 1.0.7
|
||||
so that bzip2 allows decompression of bz2 files that
|
||||
use (too) many selectors again.
|
||||
|
||||
* Fix handling of large (> 4GB) files on Windows.
|
||||
|
||||
* Cleanup of bzdiff and bzgrep scripts so they don't use
|
||||
any bash extensions and handle multiple archives correctly.
|
||||
|
||||
* There is now a bz2-files testsuite at
|
||||
https://sourceware.org/git/bzip2-tests.git

looping. However, this count-scaling step is only needed if

one of the generated Huffman code words is longer than

maxLen, which up to and including version 1.0.2 was 20 bits,

changed to 17 bits, which has minimal effect on compression

ratio, but does mean this scaling step is used from time to

time, enough to verify that it works.
|

|

This means that bzip2-1.0.3 and later will only produce
|

Huffman codes with a maximum length of 17 bits. However, in

order to preserve backwards compatibility with bitstreams

produced by versions pre-1.0.3, the decompressor must still

XZ Utils Licensing
|
||||
==================
|
||||
|
||||
Different licenses apply to different files in this package. Here
|
||||
is a rough summary of which licenses apply to which parts of this
|
||||
package (but check the individual files to be sure!):
|
||||
|
||||
- liblzma is in the public domain.
|
||||
|
||||
- xz, xzdec, and lzmadec command line tools are in the public
|
||||
domain unless GNU getopt_long had to be compiled and linked
|
||||
in from the lib directory. The getopt_long code is under
|
||||
GNU LGPLv2.1+.
|
||||
|
||||
- The scripts to grep, diff, and view compressed files have been
|
||||
adapted from gzip. These scripts and their documentation are
|
||||
under GNU GPLv2+.
|
||||
|
||||
- All the documentation in the doc directory and most of the
|
||||
XZ Utils specific documentation files in other directories
|
||||
are in the public domain.
|
||||
|
||||
- Translated messages are in the public domain.
|
||||
|
||||
- The build system contains public domain files, and files that
|
||||
are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
|
||||
in the binaries being built.
|
||||
|
||||
- Test files and test code in the tests directory, and debugging
|
||||
utilities in the debug directory are in the public domain.
|
||||
|
||||
- The extra directory may contain public domain files, and files
|
||||
that are under various free software licenses.
|
||||
|
||||
You can do whatever you want with the files that have been put into
|
||||
the public domain. If you find public domain legally problematic,
|
||||
take the previous sentence as a license grant. If you still find
|
||||
the lack of copyright legally problematic, you have too many
|
||||
lawyers.
|
||||
|
||||
As usual, this software is provided "as is", without any warranty.
|
||||
|
||||
If you copy significant amounts of public domain code from XZ Utils
|
||||
into your project, acknowledging this somewhere in your software is
|
||||
polite (especially if it is proprietary, non-free software), but
|
||||
naturally it is not legally required. Here is an example of a good
|
||||
notice to put into "about box" or into documentation:
|
||||
|
||||
This software includes code from XZ Utils <https://tukaani.org/xz/>.
|
||||
|
||||
The following license texts are included in the following files:
|
||||
- COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
|
||||
- COPYING.GPLv2: GNU General Public License version 2
|
||||
- COPYING.GPLv3: GNU General Public License version 3
|
||||
|
||||
Note that the toolchain (compiler, linker etc.) may add some code
|
||||
pieces that are copyrighted. Thus, it is possible that e.g. liblzma
|
||||
binary wouldn't actually be in the public domain in its entirety
|
||||
even though it contains no copyrighted code from the XZ Utils source
|
||||
package.
|
||||
|
||||
If you have questions, don't hesitate to ask the author(s) for more
|
||||
information.

* \file api/lzma.h
|
||||
* \brief The public API of liblzma data compression library
|
||||
*
|
||||
* liblzma is a public domain general-purpose data compression library with
|
||||
* a zlib-like API. The native file format is .xz, but also the old .lzma
|
||||
* format and raw (no headers) streams are supported. Multiple compression
|
||||
* algorithms (filters) are supported. Currently LZMA2 is the primary filter.
|
||||
*
|
||||
* liblzma is part of XZ Utils <http://tukaani.org/xz/>. XZ Utils includes
|
||||
* a gzip-like command line tool named xz and some other tools. XZ Utils
|
||||
* is developed and maintained by Lasse Collin.
|
||||
*
|
||||
* Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK
|
||||
* <http://7-zip.org/sdk.html>.
|
||||
*
|
||||
* The SHA-256 implementation is based on the public domain code found from
|
||||
* 7-Zip <http://7-zip.org/>, which has a modified version of the public
|
||||
* domain SHA-256 code found from Crypto++ <http://www.cryptopp.com/>.
|
||||
* The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

/*****************************
|

* Required standard headers *
|
||||
*****************************/
|
||||
|
||||
/*
|
||||
* liblzma API headers need some standard types and macros. To allow
|
||||
* including lzma.h without requiring the application to include other
|
||||
* headers first, lzma.h includes the required standard headers unless
|
||||
* they already seem to be included already or if LZMA_MANUAL_HEADERS
|
||||
* has been defined.
|
||||
*
|
||||
* Here's what types and macros are needed and from which headers:
|
||||
* - stddef.h: size_t, NULL
|
||||
* - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n),
|
||||
* UINT32_MAX, UINT64_MAX
|
||||
*
|
||||
* However, inttypes.h is a little more portable than stdint.h, although
|
||||
* inttypes.h declares some unneeded things compared to plain stdint.h.
|
||||
*
|
||||
* The hacks below aren't perfect, specifically they assume that inttypes.h
|
||||
* exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
|
||||
* and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
|
||||
* If the application already takes care of setting up all the types and
|
||||
* macros properly (for example by using gnulib's stdint.h or inttypes.h),
|
||||
* we try to detect that the macros are already defined and don't include
|
||||
* inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
|
||||
* force this file to never include any system headers.
|
||||
*
|
||||
* Some could argue that liblzma API should provide all the required types,
|
||||
* for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
|
||||
* seen as an unnecessary mess, since most systems already provide all the
|
||||
* necessary types and macros in the standard headers.
|
||||
*
|
||||
* Note that liblzma API still has lzma_bool, because using stdbool.h would
|
||||
* break C89 and C++ programs on many systems. sizeof(bool) in C99 isn't
|
||||
* necessarily the same as sizeof(bool) in C++.
|

* thus they cannot be used to compile liblzma. Using an
|
||||
* existing liblzma.dll with old MSVC can work though(*),
|
||||
* but we need to define the required standard integer
|
||||
* types here in a MSVC-specific way.
|
||||
*
|
||||
* (*) If you do this, the existing liblzma.dll probably uses
|
||||
* a different runtime library than your MSVC-built
|
||||
* application. Mixing runtimes is generally bad, but
|
||||
* in this case it should work as long as you avoid
|

* the few rarely-needed liblzma functions that allocate

* memory and expect the caller to free it using free().
