2009-04-28Fixed a crash in liblzma.Lasse Collin1-1/+1
liblzma tries to avoid useless free()/malloc() pairs in initialization when multiple files are handled using the same lzma_stream. This didn't work with filter chains due to comparison of wrong pointers in lzma_next_coder_init(), making liblzma think that no memory reallocation is needed even when it actually is. Easy way to trigger this bug is to decompress two files with a single xz command. The first file should have e.g. x86+LZMA2 as the filter chain, and the second file just LZMA2.
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-10/+3
Some minor documentation cleanups were made at the same time.
2009-02-02Modify LZMA_API macro so that it works on Windows withLasse Collin1-1/+1
other compilers than MinGW. This may hurt readability of the API headers slightly, but I don't know any better way to do this.
2009-01-25Fix a dumb bug in Block decoder, which made it returnLasse Collin1-3/+3
LZMA_DATA_ERROR with valid data. The bug was added in e114502b2bc371e4a45449832cb69be036360722.
2008-12-27Bunch of liblzma tweaks, including some API changes.Lasse Collin1-27/+27
The API and ABI should now be very close to stable, although the code behind it isn't yet.
2008-11-19Oh well, big messy commit again. Some highlights:Lasse Collin1-30/+29
- 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
2008-09-13Renamed constants:Lasse Collin1-6/+6
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR
2008-09-10Cleaned up Block encoder and moved the no longer sharedLasse Collin1-1/+22
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.
2008-09-04Don't allow LZMA_SYNC_FLUSH with decoders anymore. There'sLasse Collin1-1/+1
simply nothing that would use it. Allow LZMA_FINISH to the decoders, which will usually ignore it (auto decoder and Stream decoder being exceptions).
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-29/+38
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.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin1-222/+76
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.
2008-01-25Combine lzma_options_block validation needed by both BlockLasse Collin1-22/+15
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. Allow encoding and decoding Blocks with combinations of fields that are not allowed by the file format specification. Doing this requires that the application passes such a combination in lzma_options_lzma; liblzma doesn't do that, but it's not impossible that someone could find them useful in some custom file format.

Cleaned Subblock filter's initialization code too.
