f42ee98166 Build system fixes 
Don't use libtool convenience libraries to avoid recently
discovered long-standing subtle but somewhat severe bugs
in libtool (at least 1.5.22 and 2.2.6 are affected). It
was found when porting XZ Utils to Windows
<http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html>
but the problem is significant also e.g. on GNU/Linux.

Unless --disable-shared is passed to configure, static
library built from a set of convenience libraries will
contain PIC objects. That is, while libtool builds non-PIC
objects too, only PIC objects will be used from the
convenience libraries. On 32-bit x86 (tested on mobile XP2400+),
using PIC instead of non-PIC makes the decompressor 10 % slower
with the default CFLAGS.

So while xz was linked against static liblzma by default,
it got the slower PIC objects unless --disable-shared was
used. I tend develop and benchmark with --disable-shared
due to faster build time, so I hadn't noticed the problem
in benchmarks earlier.

This commit also adds support for building Windows resources
into liblzma and executables.

to prepare for building them with Autotools.

b2b1f86753 Hopefully improved portability of the assembler code in 
Autotools based builds on Windows.

390a640856 Basic support for building with Cygwin and MinGW using 
the Autotools based build system. It's not good yet, more
fixes will follow.

1c9360b7d1 Fix @variables@ to $(variables) in Makefile.am files. 
Fix the ordering of libgnu.a and LTLIBINTL on the linker
command line and added missing LTLIBINTL to tests/Makefile.am.

1774f27c61 Fix purporse -> purpose. Thanks to Andrew Dudman. 
Released .xz spec 1.0.2 due to this fix too.

083c23c680 Make the raw value of the Check field available to applications 
via lzma_block structure.

This changes ABI but not doesn't break API.

a6f43e6412 Use a GCC-specific #pragma instead of GCC-specific 
-Wno-uninitialized to silence a bogus warning.

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).

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

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

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

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.

96c46df7de Improve support for DOS-like systems. 
Here DOS-like means DOS, Windows, and OS/2.

a3bbbe05d3 Let the user specify custom CFLAGS on the make command 
line. Previously custom CFLAGS worked only when they were
passed to configure.

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.

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.

99c1c2abfa Updated the x86 assembler code: 
- Use call/ret pair to get instruction pointer for PIC.
  - Use PIC only if PIC or __PIC__ is #defined.
  - The code should work on MinGW and Darwin in addition
    to GNU/Linux and Solaris.
 2009-02-02 21:19:01 +02:00

22a0c6dd94 Modify LZMA_API macro so that it works on Windows with 
other compilers than MinGW. This may hurt readability
of the API headers slightly, but I don't know any
better way to do this.

8dd7b6052e Fix a bug in lzma_block_buffer_decode(), although this 
function should be rewritten anyway.

55fd41431e Added initial version of raw buffer-to-buffer coding 
functions, and cleaned up filter.h API header a little.
May be very buggy, not tested yet.

d64ca34f1b Use __cdecl also for function pointers in liblzma API when 
on Windows.
 2009-02-01 00:10:07 +02:00
Lasse Collin
6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least 
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.

beginning of the line.

4ab7601091 Add support for using liblzma headers in MSVC, which has no 
stdint.h or inttypes.h.

3241317093 Fix uninitialized variables in alone_decoder.c. This bug was 
triggered by the previous commit, since these variables were
not used by anything before support for a preset dictionary.
 2009-01-28 08:43:26 +02:00
Lasse Collin
f76e39cf93 Added initial support for preset dictionary for raw LZMA1 
and LZMA2. It is not supported by the .xz format or the xz
command line tool yet.

2c5fe958e4 Fix a dumb bug in Block decoder, which made it return 
LZMA_DATA_ERROR with valid data. The bug was added in

128586213f Beta was supposed to be API stable but I had forgot to rename 
lzma_memlimit_encoder and lzma_memlimit_decoder to
lzma_raw_encoder_memlimit and lzma_raw_decoder_memlimit. :-(
Now it is fixed. Hopefully it doesn't cause too much trouble
to those who already thought API is stable.
