2008-01-15Revised the fastpos code. It now uses the slightly fasterLasse Collin9-44/+746
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.
2008-01-15Removed a few unused macros from lzma_common.h.Lasse Collin1-6/+2
2008-01-15Fix a typo in lzma_encoder.c.Lasse Collin1-1/+1
2008-01-15Convert bittree_get_price() and bittree_reverse_get_price()Lasse Collin2-22/+13
from macros to inline functions.
2008-01-14Remove RC_BUFFER_SIZE from lzma_encoder_private.hLasse Collin1-2/+4
and replace it with a sanity check.
2008-01-14Major changes to LZ encoder, LZMA encoder, and range encoder.Lasse Collin1-31/+43
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.
2008-01-14In lzma_read_match_distances(), don't useLasse Collin1-3/+3
coder->lz.stream_end_was_reached. That variable will be removed, and the check isn't required anyway. Rearrange the check so that it doesn't make one to think that there could be an integer overflow.
2008-01-14More fixes to LZMA decoder's flush marker handling.Lasse Collin1-22/+30
2008-01-05Another bug fix for flush marker detection.Lasse Collin1-1/+9
2008-01-04Fix stupid bugs in flush marker detection.Lasse Collin1-3/+4
2008-01-04Added support for flush marker, which will be in filesLasse Collin2-117/+104
that use LZMA_SYNC_FLUSH with encoder (not implemented yet). This is a new feature in the raw LZMA format, which isn't supported by old decoders. This shouldn't be a problem in practice, since lzma_alone_encoder() will not allow LZMA_SYNC_FLUSH, and thus not allow creating files on decodable with old decoders. Made lzma_decoder.c to require tab width of 4 characters if one wants to fit the code in 80 columns. This makes the code easier to read.
2008-01-04Moved range decoder initialization (reading the firstLasse Collin1-36/+6
five input bytes) from LZMA decoder to range decoder header. Did the same for decoding of direct bits.
