Lasse Collin 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.

Lasse Collin 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).

Lasse Collin 02ddf09bc3 Put the interesting parts of XZ Utils into the public domain.
Some minor documentation cleanups were made at the same time.

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

Thanks to Bert Wesarg.

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

Lasse Collin cf751edfde Added AC_CONFIG_MACRO_DIR to configure.ac. 2009-03-01 09:00:06 +02:00
Lasse Collin 63df14c57d Fix the Autoconf test for getopt_long replacement.
It was broken by e114502b2b.

Lasse Collin fd6a380f4e Add a rough explanation of --extreme to output of --help. 2009-02-22 19:07:54 +02:00
Lasse Collin 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.

Lasse Collin 47c2e21f82 Added files missing from the previous commit. 2009-02-18 13:00:10 +02:00
Lasse Collin 489a3dbaa0 Added lzma_easy_buffer_encode(). Splitted easy.c into small
pieces to avoid unneeded dependencies making statically
linked applications bigger than needed.

Lasse Collin 7494816ab0 Make physmem.h work on old Windows versions.
Thanks to Hongbo Ni for the original patch.

Lasse Collin 11ae4ae35f Fix microsecond vs. nanosecond confusion in my_time(). 2009-02-14 20:44:52 +02:00
Lasse Collin 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.

Lasse Collin 9c62371eab Initial port to DOS using DJGPP. 2009-02-13 18:23:50 +02:00
Lasse Collin 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.

Lasse Collin 1d924e584b Fix handling of integrity check type in the xz command line tool. 2009-02-13 17:30:30 +02:00
Lasse Collin 96c46df7de Improve support for DOS-like systems.
Here DOS-like means DOS, Windows, and OS/2.

Lasse Collin b6a30ee8c2 Remove dead directories from .gitignore. 2009-02-11 20:02:32 +02:00
Jim Meyering 1ec5b00279 .gitignore vs. Makefiles
How about this for those of us who do srcdir builds?
2009-02-11 20:01:10 +02:00
Lasse Collin 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.

Lasse Collin e605c26636 Added resource files for the Windows build. 2009-02-10 21:48:05 +02:00
Lasse Collin a3bbbe05d3 Let the user specify custom CFLAGS on the make command
line. Previously custom CFLAGS worked only when they were
passed to configure.

Lasse Collin 53f7598998 Fix aliasing issue in physmem.h. 2009-02-08 21:35:11 +02:00
Lasse Collin 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.
2009-02-08 18:24:50 +02:00
Lasse Collin ae1ad9af54 Make "xz --force" to write to terminal as the error
message suggests.

separator on Windows when parsing argv[0].

Lasse Collin bc7c7109cc Omit the wrong and (even if corrected) nowadays useless rm
from autogen.sh.

Lasse Collin edfc2031e5 Updated THANKS. 2009-02-07 21:41:52 +02:00
Lasse Collin 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.

Lasse Collin d0ab8c1c73 MinGW support: Don't build fastpos_tablegen.c as part of

static and dynamic versions of the command line tools.

Lasse Collin bfd91198e4 Support LZMA_API_STATIC in assembler files to
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.

install.exe, so don't rely on it.

Lasse Collin 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.
