Lasse Collin 33be3c0e24 Subblock decoder: Don't exit the main loop in decode_buffer() 
too early if we hit End of Input while decoding a Subblock of
type Repeating Data. To keep the loop termination condition
elegant, the order of enumerations in coder->sequence were
changed.

To keep the case-labels in roughly the same order as the
enumerations in coder->sequence, large chunks of code was
moved around. This made the diff big and ugly compared to
the amount of the actual changes made.

Lasse Collin b254bd97b1 Fix wrong too small size of argument unfiltered_max 
in ia64_coder_init(). It triggered assert() in
simple_coder.c, and could have caused a buffer overflow.

This error was probably a copypaste mistake, since most
of the simple filters use unfiltered_max = 4.

Lasse Collin 8f5794c8f1 Added --delta to the output of "lzma --help". 2008-01-17 17:27:45 +02:00
Lasse Collin f88590e001 Fix Subblock docoder: If Subblock filter was used with known 
Uncompressed Size, and the last output byte was from RLE,
the code didn't stop decoding as it should have done.

Lasse Collin 9bc33a54cb Make Uncompresed Size validation more strict 
in alone_decoder.c.
 2008-01-16 13:27:03 +02:00
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.
 2008-01-15 14:02:22 +02:00
Lasse Collin 10437b5b56 Added bsr.h. 2008-01-15 13:32:13 +02:00

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

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
