Put the interesting parts of XZ Utils into the public domain.
...
Some minor documentation cleanups were made at the same time.

Fix off-by-one in LZ decoder.

Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.

Fixes to progress message handling in xz:
...
- Don't use Windows-specific code on Windows. The old code
required at least Windows 2000. Now it should work on
Windows 98 and later, and maybe on Windows 95 too.
- Use less precision when showing estimated remaining time.
- Fix some small design issues.

Added lzma_easy_buffer_encode(). Splitted easy.c into small

2009-02-14 20:44:52 +02:00
3084d662d2
Cleanups to the code that detects the amount of RAM and
...
the number of CPU cores. Added support for using sysinfo()
on Linux systems whose libc lacks appropriate sysconf()
support (at least dietlibc). The Autoconf macros were
split into separate files, and CPU core count detection
was moved from hardware.c to cpucores.h. The core count
isn't used for anything real for now, so a problematic
part in process.c was commented out.
2009-02-14 00:45:29 +02:00
fdbc0cfa71
Changed how the version number is specified in various places.
...
Now configure.ac will get the version number directly from
src/liblzma/api/lzma/version.h. The intent is to reduce the
number of places where the version number is duplicated. In
future, support for displaying Git commit ID may be added too.

Fix aliasing issue in physmem.h.

0e27028d74
Add a separate internal function to initialize the CRC32
...
table, which is used also by LZ encoder. This was needed
because calling lzma_crc32() and ignoring the result is
a no-op due to lzma_attr_pure.

Make it easy to choose if command line tools should be
...
linked statically or dynamically against liblzma. The
default is still to use static liblzma, but it can now
be changed by passing --enable-dynamic to configure.
Thanks to Mike Frysinger for the original patch.
Fixed a few minor bugs in configure.ac.

2009-02-07 15:55:47 +02:00
3306cf3883
Introduced LZMA_API_STATIC macro, which the applications
...
need to #define when linking against static liblzma on
platforms like Windows. Most developers don't need to
care about LZMA_API_STATIC at all.

Updated the x86 assembler code:
...
- Use call/ret pair to get instruction pointer for PIC.
- Use PIC only if PIC or __PIC__ is #defined.
- The code should work on MinGW and Darwin in addition
to GNU/Linux and Solaris.
2009-02-02 21:19:01 +02:00

Modify LZMA_API macro so that it works on Windows with

other compilers than MinGW. This may hurt readability
of the API headers slightly, but I don't know any
better way to do this.

6a2eb54092
Add LZMA_API to liblzma API headers. It's useful at least

not used by anything before support for a preset dictionary.
2009-01-28 08:43:26 +02:00
f76e39cf93
Added initial support for preset dictionary for raw LZMA1

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.

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.
2008-12-31 16:29:39 +02:00
28e75f7086
Updated src/liblzma/Makefile.am to use liblzma.pc.in, which

should have been in the previous commit.
2008-12-31 00:48:23 +02:00
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.

Revert a change made in 3b34851de1

that was related to LZMA_MODE_FAST. The original code is slightly
faster although it compresses slightly worse. But since it is fast
mode, it is better to select the faster version.

Renamed lzma to xz and lzmadec to xzdec. We create symlinks

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.
