Lasse Collin 1a7ec87c8e Revised the Index handling code.
This breaks API and ABI but most apps are not affected
since most apps don't use this part of the API. You will
get a compile error if you are using anything that got
broken.

Summary of changes:

  - Ability to store Stream Flags, which are needed
    for random-access reading in multi-Stream files.

  - Separate function to set size of Stream Padding.

  - Iterator structure makes it possible to read the same
    lzma_index from multiple threads at the same time.

  - A lot faster code to locate Blocks.

  - Removed lzma_index_equal() without adding anything
    to replace it. I don't know what it should do exactly
    with the new features and what actually needs this
    function in the first place other than test_index.c,
    which now has its own code to compare lzma_indexes.

Lasse Collin 8767b41534 Fix a memory leak in test_index.c.
This was introduced in
bd13b04e20.

Thanks to Jim Meyering for noticing it.

Lasse Collin bd13b04e20 Fix bugs in lzma_index_read() and lzma_index_cat().
lzma_index_read() didn't skip over Stream Padding
if it was the first record in the Index.

lzma_index_cat() didn't combine small Indexes correctly.

The test suite was updated to check for these bugs.

These bugs didn't affect the xz command line tool or
most users of liblzma in any way.

Lasse Collin ebfb2c5e1f Use a tuklib module for integer handling.
This replaces bswap.h and integer.h.

The tuklib module uses <byteswap.h> on GNU,
<sys/endian.h> on *BSDs and <sys/byteorder.h>
on Solaris, which may contain optimized code
like inline assembly.

Lasse Collin 18a4233a53 Fix a couple of warnings. 2009-09-11 09:25:09 +03:00
Lasse Collin 7653d1cf48 Use static liblzma by default also for tests. 2009-06-30 17:14:39 +03:00
Lasse Collin 1c9360b7d1 Fix @variables@ to $(variables) in Makefile.am files.
Fix the ordering of libgnu.a and LTLIBINTL on the linker
command line and added missing LTLIBINTL to tests/Makefile.am.

Lasse Collin 31decdce04 Minor fixes to test files' README. 2009-04-14 11:48:46 +03:00
Lasse Collin 02ddf09bc3 Put the interesting parts of XZ Utils into the public domain.
Some minor documentation cleanups were made at the same time.

Lasse Collin 975d8fd72a Recreated the BCJ test files for x86 and SPARC. The old files
were linked with crt*.o, which are copyrighted, and thus the
old test files were not in the public domain as a whole. They
are freely distributable though, but it is better to be careful
and avoid including any copyrighted pieces in the test files.
The new files are just compiled and assembled object files,
and thus don't contain any copyrighted code.
2009-02-06 09:13:15 +02:00
Lasse Collin 6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.

Jim Meyering 850f740042 remove trailing blanks from all but .xz files 2009-01-26 20:01:51 +02:00
Lasse Collin 9ec80355a7 Add some single-call buffer-to-buffer coding functions. 2009-01-20 16:37:27 +02:00
Lasse Collin 061748f593 Disable Subblock filter from test_compress.sh since it is
disabled by default in configure.ac.
2008-12-31 18:59:02 +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 5cda29b566 Use 28 MiB as memory usage limit for encoding in test_compress.sh. 2008-12-27 19:40:31 +02:00
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 1880a3927b Renamed lzma to xz and lzmadec to xzdec. We create symlinks
lzma, unlzma, and lzcat in "make install" for backwards
compatibility with LZMA Utils 4.32.x; I'm not sure if this
should be the default though.
2008-11-19 23:52:24 +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

2008-10-09 11:12:29 +03:00
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.
2008-10-02 22:51:46 +03:00

  - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN
  - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR

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 57b9a145a5 Fix test_filter_flags to match the new restriction of lc+lp. 2008-06-20 17:16:32 +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.

liblzma's API.
