Lasse Collin bd137524f2 Initial changes to change the suffix of the new format to .xz. 
This also fixes a bug related to --suffix option. Some issues
with suffixes with --format=raw were not fixed.

 2008-09-27 23:01:15 +03:00
Lasse Collin c6ca26eef7 Updated file format specification. It changes the suffix 
of the new format to .xz and removes the recently added
LZMA filter.

 2008-09-13 12:10:43 +03:00
Lasse Collin 320601b2c7 Improved the Stream Flags handling API. 2008-09-12 22:41:40 +03:00
Lasse Collin ec490da522 Simplified debug/known_sizes.c to match the relaxed 
requirements of Block encoder.
 2008-09-11 23:10:44 +03:00
Lasse Collin 16e8b98f26 Remove a check from Block encoder that should have already 
been removed in 2ba01bfa75.

Lasse Collin 962f2231d4 Fix a compiler error on big endian systems that don't 
support unaligned memory access.
 2008-09-11 10:48:12 +03:00
Lasse Collin fa3ab0df8a Silence a compiler warning. 2008-09-11 10:46:14 +03:00
Lasse Collin 9373e81e18 Bumped version to 4.999.6alpha. 2008-09-10 19:16:32 +03:00
Lasse Collin cb072b7c84 Check for LZMA_FILTER_RESERVED_START in filter_flags_encoder.c. 
Use LZMA_PROG_ERROR instead of LZMA_HEADER_ERROR if the Filter ID
is in the reserved range. This allows Block Header encoder to
detect unallowed Filter IDs, which is good for Stream encoder.

Lasse Collin 123ab0acec Filter handling cleanups 2008-09-10 16:44:32 +03:00
Lasse Collin 9cfcd0c4f2 Comments 2008-09-10 00:33:00 +03:00
Lasse Collin 2ba01bfa75 Cleaned up Block encoder and moved the no longer shared 
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.
 2008-09-10 00:27:02 +03:00
Lasse Collin 07efcb5a6b Changed Filter ID of LZMA to 0x20. 2008-09-07 10:23:13 +03:00
Lasse Collin 32fe5fa541 Comments 2008-09-06 23:42:50 +03:00
Lasse Collin 0a31ed9d5e Some API cleanups 2008-09-06 15:14:30 +03:00
Lasse Collin da98df5440 Added support for raw encoding and decoding to the command 
line tool, and made various cleanups. --lzma was renamed to
--lzma1 to prevent people from accidentally using LZMA when
they want LZMA2.
 2008-09-04 11:53:06 +03:00
Lasse Collin 2496aee8a7 Don't allow LZMA_SYNC_FLUSH with decoders anymore. There's 
simply nothing that would use it. Allow LZMA_FINISH to the
decoders, which will usually ignore it (auto decoder and
Stream decoder being exceptions).
 2008-09-04 10:39:15 +03:00
Lasse Collin bea301c26d Minor updates to the file format specification. 2008-09-03 17:06:25 +03:00
Lasse Collin 9c75b089b4 Command line tool fixes 2008-09-02 19:33:32 +03:00
Lasse Collin bab0590504 Auto decoder cleanup 2008-09-02 19:31:42 +03:00
Lasse Collin 689602336d Updated auto decoder to handle LZMA_CONCATENATED when decoding 
LZMA_Alone files. Decoding of concatenated LZMA_Alone files is
intentionally not supported, so it is better to put this in
auto decoder than LZMA_Alone decoder.

Lasse Collin fc68165745 Some fixes to LZ encoder. 2008-09-02 11:45:39 +03:00
Lasse Collin ede675f9ac Fix wrong pointer calculation in LZMA encoder. 2008-08-31 11:47:01 +03:00
Lasse Collin 3b34851de1 Sort of garbage collection commit. :-| Many things are still 
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.
 2008-08-28 22:53:15 +03:00
Lasse Collin 57b9a145a5 Fix test_filter_flags to match the new restriction of lc+lp. 2008-06-20 17:16:32 +03:00
Lasse Collin eaafc4367c Remove some redundant code from LZMA encoder. 2008-06-20 16:19:54 +03:00
Lasse Collin 0809c46534 Add limit of lc + lp <= 4. Now we can allocate the 
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.

Lasse Collin d25ab1b961 Comments 2008-06-18 21:45:19 +03:00
Lasse Collin 6368a2fa59 Delete old code that was supposed to be already deleted 
from test_block_header.c.
 2008-06-18 19:19:02 +03:00
Lasse Collin 7d17818cec Update the code to mostly match the new simpler file format 
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.
 2008-06-18 18:02:10 +03:00
Lasse Collin bf6348d1a3 Update the file format specification draft. The new one is 
a lot simpler than the previous versions, but it also means
that the existing code will change a lot.
 2008-06-17 15:03:46 +03:00
Lasse Collin 803194ddd2 Fix uninitialized variable in LZMA encoder. This was 
introduced in 369f72fd65.
