2009-01-17Beta was supposed to be API stable but I had forgot to renameLasse Collin1-2/+2
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.
2008-12-31Bumped version to 4.999.8beta right after the releaseLasse Collin1-1/+1
of 4.999.7beta.
2008-12-31Prepare for 4.999.7beta release.Lasse Collin1-1/+1
2008-12-31Cleaned up some comments in the API headers.Lasse Collin3-14/+15
2008-12-31Renamed lzma_options_simple to lzma_options_bcj in the API.Lasse Collin1-11/+11
The internal implementation is still using the name "simple". It may need some cleanups, so I look at it later.
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin1-85/+0
Half of developers were already forgetting to use these functions, which could have caused total breakage in some future liblzma version or even now if --enable-small was used. Now liblzma uses pthread_once() to do the initializations unless it has been built with --disable-threads which make these initializations thread-unsafe. When --enable-small isn't used, liblzma currently gets needlessly linked against libpthread (on systems that have it). While it is stupid for now, liblzma will need threads in future anyway, so this stupidity will be temporary only. When --enable-small is used, different code CRC32 and CRC64 is now used than without --enable-small. This made the resulting binary slightly smaller, but the main reason was to clean it up and to handle the lack of lzma_init_check(). The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not sure if it works correctly and portably for static linking (Libs.private includes -pthread or other operating system specific flags). Hopefully someone complains if it is bad. lzma_rc_prices[] is now included as a precomputed array even with --enable-small. It's just 128 bytes now that it uses uint8_t instead of uint32_t. Smaller array seemed to be at least as fast as the more bloated uint32_t array on x86; hopefully it's not bad on other architectures.
2008-12-27Bunch of liblzma tweaks, including some API changes.Lasse Collin3-57/+123
The API and ABI should now be very close to stable, although the code behind it isn't yet.
2008-12-17Remove the alignment functions for now. Maybe they willLasse Collin1-60/+0
be added back in some form later, but the current version wasn't modular, so it would need fixing anyway.
2008-12-15Bunch of liblzma API cleanups and fixes.Lasse Collin14-299/+518
2008-11-25Remove the nowadays unneeded memory limitting malloc() wrapper.Lasse Collin1-207/+0
2008-11-19Oh well, big messy commit again. Some highlights:Lasse Collin4-24/+55
- Updated to the latest, probably final file format version. - Command line tool reworked to not use threads anymore. Threading will probably go into liblzma anyway. - Memory usage limit is now about 30 % for uncompression and about 90 % for compression. - Progress indicator with --verbose - Simplified --help and full --long-help - Upgraded to the last LGPLv2.1+ getopt_long from gnulib. - Some bug fixes
2008-10-07Made the preset numbering more logical in liblzma API.Lasse Collin2-11/+11
2008-09-27Some API changes, bug fixes, cleanups etc.Lasse Collin2-89/+149
2008-09-17Miscellaneous LZ and LZMA encoder cleanupsLasse Collin1-14/+0
2008-09-13Renamed constants:Lasse Collin10-59/+59
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR
2008-09-12Improved the Stream Flags handling API.Lasse Collin1-4/+80
2008-09-10Bumped version to 4.999.6alpha.Lasse Collin1-1/+1
2008-09-10Filter handling cleanupsLasse Collin1-31/+102
2008-09-10Cleaned up Block encoder and moved the no longer sharedLasse Collin1-3/+0
code from block_private.h to block_decoder.c. Now the Block encoder doesn't need compressed_size and uncompressed_size from lzma_block structure to be initialized.
2008-09-07Changed Filter ID of LZMA to 0x20.Lasse Collin1-1/+1
2008-09-06CommentsLasse Collin2-30/+57
2008-09-06Some API cleanupsLasse Collin3-127/+237
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin21-628/+655
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
2008-06-19Add limit of lc + lp <= 4. Now we can allocate theLasse Collin1-1/+9
literal coder as part of the main LZMA encoder or decoder structure. Make the LZMA decoder to rely on the current internal API to free the allocated memory in case an error occurs.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin19-1188/+522
specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.
2008-05-06Bunch of grammar fixes from meyering.Lasse Collin1-3/+3
2008-05-06Typo fixLasse Collin1-1/+1
2008-04-28Fixed wrong spelling "limitter" to "limiter". This affectsLasse Collin3-9/+9
liblzma's API.
2008-04-25Bumped version number to 4.999.3alpha. It will become 5.0.0Lasse Collin1-12/+10
once we have a stable release (won't be very soon). The version number is no longer related to version of LZMA SDK. Made some small Automake-related changes to toplevel Makefile.am and configure.ac.
2008-03-14Fix a comment API header.Lasse Collin1-1/+1
2008-03-12Make lzma_stream.next_in const. Let's see if anyone complains.Lasse Collin1-1/+1
2008-01-26Added api/lzma/easy.h. I had forgot to add this to theLasse Collin1-0/+174
git repo. Thanks to Stephan Kulow.
2008-01-26Return LZMA_HEADER_ERROR if LZMA_SYNC_FLUSH is used with anyLasse Collin1-0/+9
of the so called simple filters. If there is demand, limited support for LZMA_SYNC_FLUSH may be added in future. After this commit, using LZMA_SYNC_FLUSH shouldn't cause undefined behavior in any situation.
2008-01-25Improved the memory limitter:Lasse Collin1-0/+35
- Added lzma_memlimit_max() and lzma_memlimit_reached() API functions. - Added simple estimation of malloc()'s memory usage overhead. - Fixed integer overflow detection in lzma_memlimit_alloc(). - Made some white space cleanups and added more comments. The description of lzma_memlimit_max() in memlimit.h is bad and should be improved.
2008-01-22Made lzma_extra pointers const in lzma_options_stream.Lasse Collin1-2/+2
2008-01-19Implemented LZMA_SYNC_FLUSH support to the Subblock encoder.Lasse Collin1-11/+18
The API for handing Subfilters was changed to make it consistent with LZMA_SYNC_FLUSH. A few sanity checks were added for Subfilter handling. Some small bugs were fixed. More comments were added.
2008-01-16Added lzma_memlimit_count().Lasse Collin1-0/+10
