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. - diff --git a/externals/bzip2/CMakeLists.txt b/externals/bzip2/CMakeLists.txt new file mode 100644 index 00000000000..3de5475610a --- /dev/null +++ b/externals/bzip2/CMakeLists.txt @@ -0,0 +1,22 @@ +# Copyright (C) 2008-2010 Trinity <http://www.trinitycore.org/> +# +# This file is free software; as a special exception the author gives +# unlimited permission to copy and/or distribute it, with or without +# modifications, as long as this notice is preserved. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY, to the extent permitted by law; without even the +# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. + +file(GLOB sources *.c) + +set(bzip2_STAT_SRCS + ${sources} +) + +include_directories( + ${CMAKE_SOURCE_DIR}/externals/zlib + ${CMAKE_CURRENT_SOURCE_DIR} +) + +add_library(bzip2 STATIC ${bzip2_STAT_SRCS}) diff --git a/externals/bzip2/LICENSE b/externals/bzip2/LICENSE deleted file mode 100644 index f420cffb67d..00000000000 --- a/externals/bzip2/LICENSE +++ /dev/null @@ -1,42 +0,0 @@ - --------------------------------------------------------------------------- - -This program, "bzip2", the associated library "libbzip2", and all -documentation, are copyright (C) 1996-2007 Julian R Seward.
