Ugly hack to make it possible to use the thousand separator

Fix the ordering of libgnu.a and LTLIBINTL on the linker

8836139b63
If xz is run as lzma, unlzma, or lzcat, simply imply
...
--format=lzma. This means that xz emulating lzma
doesn't decompress .xz files, while before this
commit it did. The new way is slightly simpler in
code and especially in upcoming documentation.
2009-05-22 12:27:43 +03:00
b0063023f8
Make the default memory usage limit 40 % of RAM for both
...
compressing and decompressing. This should be OK now that
xz automatically scales down the compression settings if
they would exceed the memory usage limit (earlier, the limit
for compression was increased to 90 % because low limit broke
scripts that used "xz -9" on systems with low RAM).
Support spcifying the memory usage limit as a percentage
of RAM (e.g. --memory=50%).
Support --threads=0 to reset the thread limit to the default
value (number of available CPU cores). Use UINT32_MAX instead
of SIZE_MAX as the maximum in args.c. hardware.c was already
expecting uint32_t value.
Cleaned up the output of --help and --long-help.
2009-05-22 11:29:50 +03:00
071b825b23
Support special value "max" where xz and xzdec accept an integer.
...
Don't round the memory usage limit in xzdec --help to avoid
an integer overflow and to not give wrong impression that
the limit is high enough when it may not actually be.
2009-05-21 17:22:01 +03:00
03ca67fd37
Install lzdiff, lzgrep, and lzmore as symlinks
...
This adds lzdiff, lzgrep, and lzmore to the list of symlinks to install.
It also installs symlinks for the manual pages and removes the new
symlinks on uninstall.
2009-05-21 16:25:36 +03:00

21c6b94373
Fixed a crash in liblzma.
...
liblzma tries to avoid useless free()/malloc() pairs in
initialization when multiple files are handled using the
same lzma_stream. This didn't work with filter chains
due to comparison of wrong pointers in lzma_next_coder_init(),
making liblzma think that no memory reallocation is needed
even when it actually is.
Easy way to trigger this bug is to decompress two files with
a single xz command. The first file should have e.g. x86+LZMA2
as the filter chain, and the second file just LZMA2.
2009-04-28 23:08:32 +03:00

Fix uint32_t -> size_t in ARM and ARM-Thumb filters.

68bf7ac298
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.

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.

Add a separate internal function to initialize the CRC32

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

Updated the x86 assembler code:

- Use call/ret pair to get instruction pointer for PIC.
- Use PIC only if PIC or __PIC__ is #defined.

to GNU/Linux and Solaris.
2009-02-02 21:19:01 +02:00

Modify LZMA_API macro so that it works on Windows with

2009-01-28 08:43:26 +02:00
f76e39cf93
Added initial support for preset dictionary for raw LZMA1

lzma_memlimit_encoder and lzma_memlimit_decoder to

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

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

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.

369f72fd65
Fix a buffer overflow in the LZMA encoder. It was due to my
...
misunderstanding of the code. There's no tiny fix for this
problem, so I also cleaned up the code in general.
This reduces the speed of the encoder 2-5 % in the fastest
compression mode ("lzma -1"). High compression modes should
have no noticeable performance difference.
This commit breaks things (especially LZMA_SYNC_FLUSH) but I
will fix them once the new format and LZMA2 has been roughly
implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all
and won't be supported in the new .lzma format. This may
change still but this is what it looks like now.
Support for known uncompressed size (that is, LZMA or LZMA2
without EOPM) is likely to go away. This means there will
be API changes.
