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.

Add -no-undefined to get shared liblzma on Windows.

Moved the Windows resource files outside the windows directory
...
to prepare for building them with Autotools.
2009-06-27 17:28:01 +03:00

Hopefully improved portability of the assembler code in
...
Autotools based builds on Windows.
2009-06-27 00:43:06 +03:00
390a640856
Basic support for building with Cygwin and MinGW using
...
the Autotools based build system. It's not good yet, more
fixes will follow.

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.
2009-06-26 14:47:31 +03:00
1774f27c61
Fix purporse -> purpose. Thanks to Andrew Dudman.
...
Released .xz spec 1.0.2 due to this fix too.
2009-06-04 22:59:55 +03:00
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.
2009-05-26 14:48:48 +03:00
a6f43e6412
Use a GCC-specific #pragma instead of GCC-specific
...
-Wno-uninitialized to silence a bogus warning.

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.

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).
2009-04-15 14:13:38 +03:00
02ddf09bc3
Put the interesting parts of XZ Utils into the public domain.
...
Some minor documentation cleanups were made at the same time.
2009-04-13 11:27:40 +03:00
e79c42d854
Fix off-by-one in LZ decoder.
...
Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.

47c2e21f82
Added files missing from the previous commit.
2009-02-18 13:00:10 +02:00
489a3dbaa0
Added lzma_easy_buffer_encode(). Splitted easy.c into small
...
pieces to avoid unneeded dependencies making statically
linked applications bigger than needed.
2009-02-17 10:43:00 +02:00
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.
2009-02-13 18:00:03 +02:00

Improve support for DOS-like systems.
...
Here DOS-like means DOS, Windows, and OS/2.
2009-02-13 17:29:02 +02:00

Let the user specify custom CFLAGS on the make command
...
line. Previously custom CFLAGS worked only when they were
passed to configure.
2009-02-09 14:54:31 +02:00
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
bfd91198e4
Support LZMA_API_STATIC in assembler files to
...
avoid __declspec(dllexport) equivalent.
2009-02-07 15:55:47 +02:00
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.
2009-02-07 11:11:50 +02:00
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.
2009-02-02 20:14:03 +02:00
8dd7b6052e
Fix a bug in lzma_block_buffer_decode(), although this
...
function should be rewritten anyway.
2009-02-01 22:40:35 +02:00
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.
2009-02-01 22:39:07 +02:00
d64ca34f1b
Use __cdecl also for function pointers in liblzma API when
...
on Windows.
2009-02-01 00:10:07 +02:00
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.
2009-01-31 11:01:48 +02:00
2dbdc5befb
Fix two lines in lzma.h on which the # wasn't at the
...
beginning of the line.
2009-01-31 10:02:52 +02:00
4ab7601091
Add support for using liblzma headers in MSVC, which has no
...
stdint.h or inttypes.h.
2009-01-31 09:55:05 +02:00
b2172cf823
Fix # -> ## in a macro in lzma.h.
2009-01-31 08:49:54 +02:00
f54bcf6f80
Remove dangling crc64_init.c.
2009-01-30 00:29:58 +02:00
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
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.
2009-01-27 18:36:05 +02:00

Add more sanity checks to lzma_stream_buffer_decode().

Avoid hardcoded constant in easy.c.
2009-01-26 14:33:13 +02:00

Tiny bit better sanity check in block_util.c
2009-01-26 13:06:49 +02:00
2c5fe958e4
Fix a dumb bug in Block decoder, which made it return
...
LZMA_DATA_ERROR with valid data. The bug was added in
e114502b2b
2009-01-25 01:35:56 +02:00
c81f13ff29
Added lzma_stream_buffer_decode() and made minor cleanups.

Fix a comment.
2009-01-22 12:53:33 +02:00

Add some single-call buffer-to-buffer coding functions.

Block encoder cleanups
2009-01-20 13:45:41 +02:00

Use LZMA_PROG_ERROR in lzma_code() as documented in base.h.
2009-01-20 10:35:15 +02:00

Fix handling of non-fatal errors in lzma_code().
2009-01-19 22:53:18 +02:00
4810b6bc25
Move some LZMA2 constants to lzma2_encoder.h so that they
...
can be used outside lzma2_encoder.c.
2009-01-19 14:00:33 +02:00

Remove dead code.

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.
