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.
2008-06-01Fix a buffer overflow in the LZMA encoder. It was due to myLasse Collin1-108/+5
misunderstanding of the code. There's no tiny fix for this problem, so I also cleaned up the code in general. This reduces the speed of the encoder 2-5 % in the fastest compression mode ("lzma -1"). High compression modes should have no noticeable performance difference. This commit breaks things (especially LZMA_SYNC_FLUSH) but I will fix them once the new format and LZMA2 has been roughly implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all and won't be supported in the new .lzma format. This may change still but this is what it looks like now. Support for known uncompressed size (that is, LZMA or LZMA2 without EOPM) is likely to go away. This means there will be API changes.

size. The "fix" breaks LZMA_SYNC_FLUSH at end of stream with known uncompressed size, but since it currently seems likely that support for encoding with known uncompressed size will go away anyway, I'm not fixing this problem now.

2008-01-18Fix LZMA_SYNC_FLUSH handling in LZ and LZMA encoders.Lasse Collin1-8/+26
That code is now almost completely in LZ coder, where it can be shared with other LZ77-based algorithms in future.
2008-01-14Major changes to LZ encoder, LZMA encoder, and range encoder.Lasse Collin1-20/+118
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.
