1496ff437c Renamed the file format specification to xz-file-format.txt 
which is the filename used on the WWW.

21c6b94373 Fixed a crash in liblzma. 
liblzma tries to avoid useless free()/malloc() pairs in
initialization when multiple files are handled using the
same lzma_stream. This didn't work with filter chains
due to comparison of wrong pointers in lzma_next_coder_init(),
making liblzma think that no memory reallocation is needed
even when it actually is.

Easy way to trigger this bug is to decompress two files with
a single xz command. The first file should have e.g. x86+LZMA2
as the filter chain, and the second file just LZMA2.

e518d167aa Fix uint32_t -> size_t in ARM and ARM-Thumb filters. 
On 64-bit system it would have gone into infinite
loop if a single input buffer was over 4 GiB (unlikely).

e79c42d854 Fix off-by-one in LZ decoder. 
Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.

0df9299e24 Test for Linux-specific sysinfo() only on Linux systems. 
Some other systems have sysinfo() with different semantics.

68bf7ac298 Fixes to progress message handling in xz: 
- Don't use Windows-specific code on Windows. The old code
    required at least Windows 2000. Now it should work on
    Windows 98 and later, and maybe on Windows 95 too.

  - Use less precision when showing estimated remaining time.

  - Fix some small design issues.

489a3dbaa0 Added lzma_easy_buffer_encode(). Splitted easy.c into small 
pieces to avoid unneeded dependencies making statically
linked applications bigger than needed.

3084d662d2 Cleanups to the code that detects the amount of RAM and 
the number of CPU cores. Added support for using sysinfo()
on Linux systems whose libc lacks appropriate sysconf()
support (at least dietlibc). The Autoconf macros were
split into separate files, and CPU core count detection
was moved from hardware.c to cpucores.h. The core count
isn't used for anything real for now, so a problematic
part in process.c was commented out.

0dae8b7751 Windows port: Take advantage of the version number macros. 
Now the version number is not duplicated in the
Windows-specific files anymore.
 2009-02-13 18:02:05 +02:00
Lasse Collin
fdbc0cfa71 Changed how the version number is specified in various places. 
Now configure.ac will get the version number directly from
src/liblzma/api/lzma/version.h. The intent is to reduce the
number of places where the version number is duplicated. In
future, support for displaying Git commit ID may be added too.

154f5aec2d Removed Makefile from .gitignore since not all Makefiles 
in the repository are generated by Autotools. People
should do test builds in a separate build directory anyway.

0e27028d74 Add a separate internal function to initialize the CRC32 
table, which is used also by LZ encoder. This was needed
because calling lzma_crc32() and ignoring the result is
a no-op due to lzma_attr_pure.

880c330938 Make it easy to choose if command line tools should be 
linked statically or dynamically against liblzma. The
default is still to use static liblzma, but it can now
be changed by passing --enable-dynamic to configure.
Thanks to Mike Frysinger for the original patch.

Fixed a few minor bugs in configure.ac.

static and dynamic versions of the command line tools.

avoid __declspec(dllexport) equivalent.
 2009-02-07 15:55:47 +02:00
Lasse Collin
3306cf3883 Introduced LZMA_API_STATIC macro, which the applications 
need to #define when linking against static liblzma on
platforms like Windows. Most developers don't need to
care about LZMA_API_STATIC at all.

975d8fd72a Recreated the BCJ test files for x86 and SPARC. The old files 
were linked with crt*.o, which are copyrighted, and thus the
old test files were not in the public domain as a whole. They
are freely distributable though, but it is better to be careful
and avoid including any copyrighted pieces in the test files.
The new files are just compiled and assembled object files,
and thus don't contain any copyrighted code.
