Lasse Collin 667481f1aa Add lzma_block_buffer_decode(). 2009-01-26 14:34:10 +02:00
Lasse Collin c81f13ff29 Added lzma_stream_buffer_decode() and made minor cleanups. 2009-01-23 22:27:50 +02:00
Lasse Collin 9ec80355a7 Add some single-call buffer-to-buffer coding functions. 2009-01-20 16:37:27 +02:00
Lasse Collin 128586213f Beta was supposed to be API stable but I had forgot to rename
lzma_memlimit_encoder and lzma_memlimit_decoder to
lzma_raw_encoder_memlimit and lzma_raw_decoder_memlimit. :-(
Now it is fixed. Hopefully it doesn't cause too much trouble
to those who already thought API is stable.

Lasse Collin 4fd43cb3a9 Bumped version to 4.999.8beta right after the release
of 4.999.7beta.

Lasse Collin d1d17a40d3 Prepare for 4.999.7beta release. 2008-12-31 17:41:46 +02:00
Lasse Collin 88d3e6b0b1 Cleaned up some comments in the API headers. 2008-12-31 17:15:03 +02:00
Lasse Collin 322ecf93c9 Renamed lzma_options_simple to lzma_options_bcj in the API.
The internal implementation is still using the name "simple".
It may need some cleanups, so I look at it later.

Lasse Collin 7ed9d943b3 Remove lzma_init() and other init functions from liblzma API.
Half of developers were already forgetting to use these
functions, which could have caused total breakage in some future
liblzma version or even now if --enable-small was used. Now
liblzma uses pthread_once() to do the initializations unless
it has been built with --disable-threads which make these
initializations thread-unsafe.

When --enable-small isn't used, liblzma currently gets needlessly
linked against libpthread (on systems that have it). While it is
stupid for now, liblzma will need threads in future anyway, so
this stupidity will be temporary only.

When --enable-small is used, different code CRC32 and CRC64 is
now used than without --enable-small. This made the resulting
binary slightly smaller, but the main reason was to clean it up
and to handle the lack of lzma_init_check().

The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not
sure if it works correctly and portably for static linking
(Libs.private includes -pthread or other operating system
specific flags). Hopefully someone complains if it is bad.

lzma_rc_prices[] is now included as a precomputed array even
with --enable-small. It's just 128 bytes now that it uses uint8_t
instead of uint32_t. Smaller array seemed to be at least as fast
as the more bloated uint32_t array on x86; hopefully it's not bad
on other architectures.

Lasse Collin e33194e79d Bunch of liblzma tweaks, including some API changes.
The API and ABI should now be very close to stable,
although the code behind it isn't yet.
2008-12-27 19:27:49 +02:00
Lasse Collin 634636fa56 Remove the alignment functions for now. Maybe they will
be added back in some form later, but the current version
wasn't modular, so it would need fixing anyway.

Lasse Collin 671a5adf1e Bunch of liblzma API cleanups and fixes. 2008-12-15 19:39:13 +02:00
Lasse Collin a8368b75cd Remove the nowadays unneeded memory limitting malloc() wrapper. 2008-11-25 02:37:47 +02:00
Lasse Collin e114502b2b Oh well, big messy commit again. Some highlights:
- 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

Lasse Collin f147666a5c Miscellaneous LZ and LZMA encoder cleanups 2008-09-17 22:11:39 +03:00
Lasse Collin 13a74b78e3 Renamed constants:
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX
  - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN
  - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR

Lasse Collin 320601b2c7 Improved the Stream Flags handling API. 2008-09-12 22:41:40 +03:00
Lasse Collin 9373e81e18 Bumped version to 4.999.6alpha. 2008-09-10 19:16:32 +03:00
Lasse Collin 123ab0acec Filter handling cleanups 2008-09-10 16:44:32 +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 0a31ed9d5e Some API cleanups 2008-09-06 15:14:30 +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 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.
2008-06-19 16:35:08 +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.

Lasse Collin 11de5d5267 Bunch of grammar fixes from meyering. 2008-05-06 15:15:07 +03:00
Lasse Collin dc192b6343 Typo fix 2008-05-06 13:41:05 +03:00
Lasse Collin 3be21fb12f Fixed wrong spelling "limitter" to "limiter". This affects
liblzma's API.
2008-04-28 17:06:34 +03:00
Lasse Collin 8f804c29aa Bumped version number to 4.999.3alpha. It will become 5.0.0
once we have a stable release (won't be very soon). The
version number is no longer related to version of LZMA SDK.

Made some small Automake-related changes to toplevel
Makefile.am and configure.ac.
2008-04-25 13:32:35 +03:00
Lasse Collin 7d516f5129 Fix a comment API header. 2008-03-14 21:32:37 +02:00
Lasse Collin 748d6e4274 Make lzma_stream.next_in const. Let's see if anyone complains. 2008-03-12 23:14:50 +02:00
Lasse Collin 4c7ad179c7 Added api/lzma/easy.h. I had forgot to add this to the
git repo. Thanks to Stephan Kulow.
2008-01-26 19:12:50 +02:00
Lasse Collin f9842f7127 Return LZMA_HEADER_ERROR if LZMA_SYNC_FLUSH is used with any
of the so called simple filters. If there is demand, limited
support for LZMA_SYNC_FLUSH may be added in future.

After this commit, using LZMA_SYNC_FLUSH shouldn't cause
undefined behavior in any situation.
2008-01-26 00:25:34 +02:00
Lasse Collin 7b8fc7e6b5 Improved the memory limitter:
- Added lzma_memlimit_max() and lzma_memlimit_reached()
    API functions.
  - Added simple estimation of malloc()'s memory usage
    overhead.
  - Fixed integer overflow detection in lzma_memlimit_alloc().
  - Made some white space cleanups and added more comments.

The description of lzma_memlimit_max() in memlimit.h is bad
and should be improved.
2008-01-25 19:20:28 +02:00
Lasse Collin cf49f42a6b Added lzma_easy_* functions. These should make using
liblzma as easy as using zlib, because the easy API
don't require developers to know any fancy LZMA options.

Note that Multi-Block Stream encoding is currently broken.
The easy API should be OK, the bug(s) are elsewhere.
2008-01-22 22:49:24 +02:00
Lasse Collin 0ed6f1adce Made lzma_extra pointers const in lzma_options_stream. 2008-01-22 00:15:11 +02:00
Lasse Collin e141fe1895 Implemented LZMA_SYNC_FLUSH support to the Subblock encoder.
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.
2008-01-19 21:16:33 +02:00
Lasse Collin 5b5b13c7bb Added lzma_memlimit_count(). 2008-01-16 14:46:50 +02:00
Lasse Collin 4e7e54c4c5 Introduced compatibility with systems that have pre-C99
or no inttypes.h. This is useful when the compiler has
good enough support for C99, but libc headers don't.

Changed liblzma API so that sys/types.h and inttypes.h
have to be #included before #including lzma.h. On systems
that don't have C99 inttypes.h, it's the problem of the
applications to provide the required types and macros
before #including lzma.h.

If lzma.h defined the missing types and macros, it could
conflict with third-party applications whose configure
has detected that the types are missing and defined them
in config.h already. An alternative would have been
introducing lzma_uint32 and similar types, but that would
just be an extra pain on modern systems.
