Update bzip from 1.0.4 to 1.0.6.
- Only adds 2 security fixes. - Add the CHANGES file. - Add local changes: + setmode to _setmode + fileno to _fileno + fdopen to _fdopen - sudonim1 removed all trailing whitespaces in svn2897 so I ran: find . -type f -name '*.c' -o -name '*.h' | xargs sed -i 's/[[:space:]]\+$//' This makes the delta of changes smaller.

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
