Lasse Collin 01d71d60b7 Free the allocated memory in lzmadec if debugging is 
enabled. This should make it possible to detect possible
memory leaks with Valgrind.
 2008-01-15 17:46:59 +02:00
Lasse Collin 8235e6e5b2 Fix memory leaks from test_block_header.c. 2008-01-15 16:25:38 +02:00
Lasse Collin f10fc6a69d Use fastpos.h when encoding LZMA dictionary size in 
Filter Flags encoder.
 2008-01-15 14:23:35 +02:00
Lasse Collin e5728142a2 Revised the fastpos code. It now uses the slightly faster 
table-based version from LZMA SDK 4.57. This should be
fast on most systems.

A simpler and smaller alternative version is also provided.
On some CPUs this can be even a little faster than the
default table-based version (see comments in fastpos.h),
but on most systems the table-based code is faster.

Lasse Collin 949d4346e2 Fix typo in test_index.c. 2008-01-15 07:41:39 +02:00
Lasse Collin d13d693155 Added precomputed range coder probability price table. 2008-01-15 07:40:21 +02:00
Lasse Collin 362dc3843b Remove RC_BUFFER_SIZE from lzma_encoder_private.h 
and replace it with a sanity check.
 2008-01-14 13:42:43 +02:00
Lasse Collin e22b37968d Major changes to LZ encoder, LZMA encoder, and range encoder. 
These changes implement support for LZMA_SYNC_FLUSH in LZMA
encoder, and move the temporary buffer needed by range encoder
from lzma_range_encoder structure to lzma_lz_encoder.
 2008-01-14 13:39:54 +02:00
Lasse Collin b59ef39737 Added one assert() to process.c of the command line tool. 2008-01-14 13:34:29 +02:00
Lasse Collin 9547e734a0 Don't use coder->lz.stream_end_was_reached in assertions 
in match_c.h.
 2008-01-14 12:09:52 +02:00
Lasse Collin 3e09e1c058 In lzma_read_match_distances(), don't use 
coder->lz.stream_end_was_reached. That variable
will be removed, and the check isn't required anyway.
Rearrange the check so that it doesn't make one to
think that there could be an integer overflow.
 2008-01-14 12:08:02 +02:00
Lasse Collin a670fec802 Small LZMA_SYNC_FLUSH fixes to Block and Single-Stream encoders. 2008-01-14 11:56:41 +02:00
Lasse Collin 3599dba957 More fixes to LZMA decoder's flush marker handling. 2008-01-14 11:54:56 +02:00
Lasse Collin f73c2ab607 Eliminate lzma_lz_encoder.must_move_pos. It's needed 
only in one place which isn't performance criticial.
 2008-01-10 17:13:42 +02:00
Lasse Collin 382808514a Define HAVE_ASM_X86 when x86 assembler optimizations are 
used. This #define will be useful for inline assembly.
 2008-01-09 20:05:57 +02:00
Lasse Collin 0e70fbe403 Added good-single-none-empty_3.lzma and 
bad-single-none-empty.lzma.
 2008-01-09 12:06:46 +02:00

Lasse Collin 97d5fa8207 Updated tests/files/README. 2008-01-08 23:10:57 +02:00

Lasse Collin 753e4d95cd Added good-single-subblock_implicit.lzma. 2008-01-08 22:27:46 +02:00
Lasse Collin faeac7b7ac Disable CRC32 from Block Headers when --check=none 
has been specified.
 2008-01-08 18:50:30 +02:00
Lasse Collin a751126dbb Fixed encoding of empty files. Arguments to is_size_valid() 
were in wrong order in block_encoder.c.
 2008-01-08 13:36:29 +02:00
Lasse Collin 9080267603 Added a few test files. 2008-01-08 13:35:36 +02:00
Lasse Collin b4943ccf73 Avoid using ! in test_files.sh, because that doesn't work 
with some ancient /bin/sh versions.
 2008-01-08 12:29:58 +02:00
Lasse Collin e2417b2b91 More pre-C99 inttypes.h compatibility fixes. Now the code 
should work even if the system has no inttypes.h.
 2008-01-08 00:48:30 +02:00
Lasse Collin 5d227e51c2 Updated fi.po although it's currently pretty much crap. 2008-01-07 23:25:32 +02:00
Lasse Collin c7189d981a Test for $GCC = yes instead of if it is non-empty. This 
way it is possible to use ac_cv_c_compiler_gnu=no to
force configure to think it is using non-GNU C compiler.
 2008-01-07 23:14:25 +02:00
Lasse Collin 3dbbea82b7 Added test_files.sh to tests/Makefile.am so it gets 
included in the tarball with "make dist".
 2008-01-07 21:49:41 +02:00
Lasse Collin 2fd2d18154 Cosmetic edit to test_files.sh. 2008-01-07 18:22:24 +02:00
Lasse Collin 9a71d57310 Added tests/files/README. 2008-01-07 18:09:44 +02:00
Lasse Collin 47f48fe993 Tell in COPYING that everything in tests/files is 
public domain.
 2008-01-07 14:20:57 +02:00
Lasse Collin 3502b3e1d0 Cleaned up the tests/files directory. 2008-01-07 14:19:05 +02:00
Lasse Collin 908b2ac604 Added test_files.sh to test decoding of the files in 
the tests/files directory. It doesn't test the malicious
files yet.
 2008-01-07 13:49:19 +02:00
Lasse Collin ecb2a6548f Updated README regarding the assembler optimizations. 2008-01-07 11:23:13 +02:00
Lasse Collin eacb805043 Updated THANKS. 2008-01-07 10:58:00 +02:00
Lasse Collin 1239649f96 Cosmetic changes to configure.ac. 2008-01-06 21:47:17 +02:00
Lasse Collin 88ee301ec2 Automatically disable assembler code on Darwin x86. 
Darwin has different ABI than GNU+Linux and Solaris,
thus the assembler code doesn't assemble on Darwin.
 2008-01-06 19:46:38 +02:00
Lasse Collin c15a7abf66 With printf(), use PRIu64 with a cast to uint64_t instead 
of %zu, because some pre-C99 libc versions don't support %zu.
 2008-01-06 19:45:27 +02:00
Lasse Collin 4e7e54c4c5 Introduced compatibility with systems that have pre-C99 
or no inttypes.h. This is useful when the compiler has
good enough support for C99, but libc headers don't.

Changed liblzma API so that sys/types.h and inttypes.h
have to be #included before #including lzma.h. On systems
that don't have C99 inttypes.h, it's the problem of the
applications to provide the required types and macros
before #including lzma.h.

If lzma.h defined the missing types and macros, it could
conflict with third-party applications whose configure
has detected that the types are missing and defined them
in config.h already. An alternative would have been
introducing lzma_uint32 and similar types, but that would
just be an extra pain on modern systems.

Lasse Collin a71864f77d Fix typo in comment (INT64_MAX -> UINT64_MAX). 2008-01-05 19:57:00 +02:00
Lasse Collin 072927905a Rearranged testing of GCC-specific flags. 2008-01-05 19:42:04 +02:00
