0541c5ea63Initialize align_price_count and match_price_count in lzma_encoder_init.c. While we don't call fill_distances_prices() and fill_align_prices() in lzma_lzma_encoder_init(), we still need to initialize these two variables so that the fill functions get called in lzma_encoder_getoptimum.c in the beginning of a stream.
Lasse Collin
2008-03-10 13:46:48 +0200
596fa1fac7Always initialize lz->temp_size in lz_decoder.c. temp_size did get initialized as a side-effect after allocating a new decoder, but not when the decoder was reused.
Lasse Collin
2008-03-10 13:44:29 +0200
45e43e1695Don't fill allocated memory with 0xFD when debugging is enabled. It hides errors from Valgrind.
Lasse Collin
2008-03-10 13:41:25 +0200
c0e19e0662Remove two redundant validity checks from the LZMA decoder. These are already checked elsewhere, so omitting these gives (very) tiny speed up.
Lasse Collin
2008-02-28 10:24:31 +0200
de74858062Tiny clean up to file-format.txt.
Lasse Collin
2008-02-06 13:25:32 +0200
1a3b218598Don't memzero() the history buffer when initializing LZ decoder. There's no danger of information leak here, so it isn't required. Doing memzero() takes a lot of time with large dictionaries, which could make it easier to construct DoS attack to consume too much CPU time.
Lasse Collin
2008-02-02 14:51:06 +0200
7e796e312bDo uncompressed size validation in raw encoder. This way it gets done for not only raw encoder, but also Block and LZMA_Alone encoders.

Lasse Collin
2008-01-25 23:50:35 +0200
4441e00418Combine lzma_options_block validation needed by both Block encoder and decoder, and put the shared things to block_private.h. Improved the checks a little so that they may detect too big Compressed Size at initialization time if lzma_options_block.total_size or .total_limit is known.
Lasse Collin
2008-01-25 23:12:36 +0200

db9df0a960Fix decoding of empty Metadata Blocks, that don't have even the Metadata Flags field. Earlier the code allowed such files; now they are prohibited as the file format specification requires.
Lasse Collin
2008-01-23 23:43:00 +0200
765f0b05f6Fix a bug related to 99e12af4e2. lzma_metadata.header_metadata_size was not properly set to zero if the Metadata had only the Metadata Flags field.

Lasse Collin
2008-01-23 13:40:45 +0200
99e12af4e2Fix Size of Header Metadata Block handling. Now lzma_metadata.header_metadata_size == LZMA_VLI_VALUE_UNKNOWN is not allowed at all. To indicate missing Header Metadata Block, header_metadata_size must be set to zero. This is what Metadata decoder does after this patch too.
Lasse Collin
2008-01-23 13:36:07 +0200

Lasse Collin
2008-01-23 00:18:32 +0200
cf49f42a6bAdded lzma_easy_* functions. These should make using liblzma as easy as using zlib, because the easy API don't require developers to know any fancy LZMA options.
Lasse Collin
2008-01-22 22:49:24 +0200
0ed6f1adceMade lzma_extra pointers const in lzma_options_stream.

Lasse Collin
2008-01-20 20:12:58 +0200

Lasse Collin
2008-01-19 21:16:33 +0200
23c227a864Revised the Delta filter implementation. The initialization function is still shared between encoder and decoder, but the actual coding is in separate files for encoder and decoder.
Lasse Collin
2008-01-19 15:19:21 +0200
61dc82f3e3Added the debug directory and the first debug tool (sync_flush). These tools are not built unless the user runs "make" in the debug directory.

2008-01-18 20:18:08 +0200
0ae3208db9Added test files to test usage of flush marker in LZMA.
Lasse Collin
2008-01-18 20:13:00 +0200
ab5feaf1fcFix LZMA_SYNC_FLUSH handling in LZ and LZMA encoders. That code is now almost completely in LZ coder, where it can be shared with other LZ77-based algorithms in future.
Lasse Collin
2008-01-18 20:02:52 +0200
079c4f7fc2Don't add -g to CFLAGS when --enable-debug is specified. It's the job of the user to put that in CFLAGS.
Lasse Collin
2008-01-18 17:21:24 +0200
61d1784d8fSet stdin and stdout to binary mode on Windows. This patch is a forward port of b7b22fcb979a16d3a47c8001f058c9f7d4416068 from lzma-utils-legacy.git. I don't know if the new code base builds on Windows, but this is a start.
Lasse Collin
2008-01-18 14:17:37 +0200
c9cba97691Added test_compress.sh and bunch of files needed by it. This new set of tests compress and decompress several test files with many different compression options. This set of tests will be extended later.
Lasse Collin
2008-01-18 00:50:29 +0200
33be3c0e24Subblock 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.
Lasse Collin
2008-01-17 18:56:53 +0200
b254bd97b1Fix 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.

Lasse Collin
2008-01-17 17:27:45 +0200
f88590e001Fix 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
2008-01-15 14:23:35 +0200
e5728142a2Revised the fastpos code. It now uses the slightly faster table-based version from LZMA SDK 4.57. This should be fast on most systems.

Lasse Collin
2008-01-14 13:42:43 +0200
e22b37968dMajor 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.

Lasse Collin
2008-01-14 12:09:52 +0200
3e09e1c058In 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.
