2008-09-27Some API changes, bug fixes, cleanups etc.Lasse Collin1-1/+1
2008-09-13Renamed constants:Lasse Collin2-12/+11
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin4-27/+27
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 Collin3-85/+34
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.
2008-01-23Fixed a typo.Lasse Collin1-1/+1
2008-01-23Fix a memory leak in the Subblock encoder.Lasse Collin1-0/+1
2008-01-20Fix alignment handling bugs in Subblock encoder.Lasse Collin1-51/+119
This leaves one known alignment bug unfixed: If repeat count doesn't fit into 28-bit integer, the encoder has to split this to multiple Subblocks with Subblock Type `Repeating Data'. The extra Subblocks may have wrong alignment. Correct alignment is restored after the split Repeating Data has been completely written out. Since the encoder doesn't even try to fix the alignment unless the size of Data is at least 4 bytes, to trigger this bug you need at least 4 GiB of repeating data with sequence length of 4 or more bytes. Since the worst thing done by this bug is misaligned data (no data corruption), this bug simply isn't worth fixing, because a proper fix isn't simple.
2008-01-19Implemented LZMA_SYNC_FLUSH support to the Subblock encoder.Lasse Collin1-67/+196
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.
2008-01-17Subblock decoder: Don't exit the main loop in decode_buffer()Lasse Collin1-133/+139
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. To keep the case-labels in roughly the same order as the enumerations in coder->sequence, large chunks of code was moved around. This made the diff big and ugly compared to the amount of the actual changes made.
2008-01-17Fix Subblock docoder: If Subblock filter was used with knownLasse Collin1-0/+6
Uncompressed Size, and the last output byte was from RLE, the code didn't stop decoding as it should have done.
2007-12-11Remove uncompressed size tracking from the filter encoders.Lasse Collin1-32/+6
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.
2007-12-11Fixed wrong type of flags_size in Subblock encoder.Lasse Collin1-1/+1
2007-12-09Take advantage of return_if_error() macro in more places.Lasse Collin2-54/+24
Cleaned Subblock filter's initialization code too.

that were disabled for debugging reasons.
