Lasse Collin 5b5b13c7bb Added lzma_memlimit_count(). 2008-01-16 14:46:50 +02:00
Lasse Collin 9bc33a54cb Make Uncompresed Size validation more strict 
in alone_decoder.c.
 2008-01-16 13:27:03 +02:00
Lasse Collin f10fc6a69d Use fastpos.h when encoding LZMA dictionary size in 
Filter Flags encoder.

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 10437b5b56 Added bsr.h. 2008-01-15 13:32:13 +02:00
Lasse Collin 78e85cb1a7 Fix CRC code in case --enable-small is used. 2008-01-15 07:44:59 +02:00
Lasse Collin d13d693155 Added precomputed range coder probability price table. 2008-01-15 07:40:21 +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 379fbbe84d Take advantage of return_if_error() in block_decoder.c. 2008-01-08 23:11:59 +02:00
Lasse Collin 7054c5f588 Fix decoding of Blocks that have only Block Header. 2008-01-08 22:58:42 +02:00
Lasse Collin a751126dbb Fixed encoding of empty files. Arguments to is_size_valid() 
were in wrong order in block_encoder.c.

Lasse Collin 918bcb0e07 Removed uncompressed size tracking from Delta encoder too. 2007-12-11 17:08:04 +02:00
Lasse Collin 3e16d51dd6 Remove uncompressed size tracking from the filter encoders. 
It's not strictly needed there, and just complicates the
code. LZ encoder never even had this feature.

The primary reason to have uncompressed size tracking in
filter encoders was validating that the application
doesn't give different amount of input that it had
promised. A side effect was to validate internal workings
of liblzma.

Uncompressed size tracking is still present in the Block
encoder. Maybe it should be added to LZMA_Alone and raw
encoders too. It's simpler to have one coder just to
validate the uncompressed size instead of having it
in every filter.

Lasse Collin 2ab8adb516 Added LZMA_SYNC_FLUSH support to the Copy filter. 2007-12-09 21:43:15 +02:00
Lasse Collin 07ac881779 Take advantage of return_if_error() macro in more places. 
Cleaned Subblock filter's initialization code too.
