Lasse Collin 1774f27c61 Fix purporse -> purpose. Thanks to Andrew Dudman.
Released .xz spec 1.0.2 due to this fix too.

Lasse Collin cb61345564 The .xz file format version 1.0.1 2009-06-01 14:53:57 +03:00
Lasse Collin 083c23c680 Make the raw value of the Check field available to applications
via lzma_block structure.

This changes ABI but not doesn't break API.
2009-05-26 14:48:48 +03:00
Lasse Collin b4f5c81409 Remove undocumented alternative option names --bcj, --ppc,
and --itanium.
2009-05-23 16:57:21 +03:00
Lasse Collin b1edee2cdc Add support for specifying the BCJ filter start offset
in the xz command line tool.
2009-05-23 15:12:23 +03:00
Lasse Collin 72aa0e9c5f Updated THANKS. 2009-05-23 14:51:09 +03:00
Lasse Collin dcedb6998c Added support for --quiet and --no-warn to xzdec.
Cleaned up the --help message a little.
2009-05-22 16:40:50 +03:00
Lasse Collin 5f735dae80 Use the 40 % of RAM memory usage limit in xzdec too.
Update the memory usage info text in --help to match
the text in xz --long-help.
2009-05-22 15:11:52 +03:00
Lasse Collin b60376249e Add --no-warn. 2009-05-22 14:43:00 +03:00
Lasse Collin b4f92f522d Fix a comment. 2009-05-22 14:27:40 +03:00
Lasse Collin 4dd21d23f2 Remove the --info option, which was an alias for --list. 2009-05-22 14:21:20 +03:00
Lasse Collin 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
Lasse Collin 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
Lasse Collin 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
ABCD 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
Lasse Collin a6f43e6412 Use a GCC-specific #pragma instead of GCC-specific
-Wno-uninitialized to silence a bogus warning.
2009-05-02 16:16:28 +03:00
Lasse Collin f6ce63ebdb Removed --disable-encoder and --disable-decoder. Use the values
given to --enable-encoders and --enable-decoders to determine
if any encoder or decoder support is wanted.
2009-05-02 14:46:50 +03:00
Lasse Collin be06858d5c Remove docs that are too outdated to be updated
(rewrite will be better).
2009-05-01 11:28:52 +03:00
Lasse Collin 0255401e57 Added documentation about the legacy .lzma file format. 2009-05-01 11:21:46 +03:00
Lasse Collin 1496ff437c Renamed the file format specification to xz-file-format.txt
which is the filename used on the WWW.

Lasse Collin 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.

Lasse Collin e518d167aa Fix uint32_t -> size_t in ARM and ARM-Thumb filters.
On 64-bit system it would have gone into infinite
loop if a single input buffer was over 4 GiB (unlikely).

Lasse Collin 31decdce04 Minor fixes to test files' README. 2009-04-14 11:48:46 +03:00
Lasse Collin 4787d65443 Updated history.txt. 2009-04-13 16:36:41 +03:00
Lasse Collin 2f0bc9cd40 Quick & dirty update to support xz in diff/grep/more scripts. 2009-04-13 14:49:48 +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.
2009-04-13 11:27:40 +03:00
Lasse Collin e79c42d854 Fix off-by-one in LZ decoder.
Fortunately, this bug had no security risk other than accepting
some corrupt files as valid.

Pavel Roskin 94eb9ad46f Fix minor typos in README 2009-03-31 21:54:06 +03:00
Lasse Collin 9bab5336eb Add a note and work-around instructions to README about
problems detecting a C99 compiler when some standard
headers are missing.

Lasse Collin a0497ff7a0 Updated THANKS. 2009-03-18 16:54:38 +02:00
Lasse Collin 390e69887f Fix wrong macro names in lc_cpucores.m4 and cpucores.h.
Thanks to Bert Wesarg.
2009-03-18 16:51:41 +02:00
Lasse Collin 0df9299e24 Test for Linux-specific sysinfo() only on Linux systems.
Some other systems have sysinfo() with different semantics.
2009-03-01 09:03:08 +02:00
Lasse Collin cf751edfde Added AC_CONFIG_MACRO_DIR to configure.ac. 2009-03-01 09:00:06 +02:00
Lasse Collin 63df14c57d Fix the Autoconf test for getopt_long replacement.
It was broken by e114502b2b.
2009-03-01 08:58:41 +02:00
Lasse Collin fd6a380f4e Add a rough explanation of --extreme to output of --help. 2009-02-22 19:07:54 +02:00
Lasse Collin 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.

Lasse Collin 47c2e21f82 Added files missing from the previous commit. 2009-02-18 13:00:10 +02:00
Lasse Collin 489a3dbaa0 Added lzma_easy_buffer_encode(). Splitted easy.c into small
pieces to avoid unneeded dependencies making statically
linked applications bigger than needed.
2009-02-17 10:43:00 +02:00
Lasse Collin 7494816ab0 Make physmem.h work on old Windows versions.
Thanks to Hongbo Ni for the original patch.
2009-02-15 15:48:45 +02:00
Lasse Collin 11ae4ae35f Fix microsecond vs. nanosecond confusion in my_time(). 2009-02-14 20:44:52 +02:00
Lasse Collin 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.

Lasse Collin 9c62371eab Initial port to DOS using DJGPP. 2009-02-13 18:23:50 +02:00
Lasse Collin 0dae8b7751 Windows port: Take advantage of the version number macros.
Now the version number is not duplicated in the
Windows-specific files anymore.
2009-02-13 18:02:05 +02:00
Lasse Collin 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.

Lasse Collin 1d924e584b Fix handling of integrity check type in the xz command line tool. 2009-02-13 17:30:30 +02:00
Lasse Collin 96c46df7de Improve support for DOS-like systems.
Here DOS-like means DOS, Windows, and OS/2.

Lasse Collin b6a30ee8c2 Remove dead directories from .gitignore. 2009-02-11 20:02:32 +02:00
Jim Meyering 1ec5b00279 .gitignore vs. Makefiles
How about this for those of us who do srcdir builds?
2009-02-11 20:01:10 +02:00
Lasse Collin 154f5aec2d Removed Makefile from .gitignore since not all Makefiles
in the repository are generated by Autotools. People
should do test builds in a separate build directory anyway.
2009-02-10 21:48:35 +02:00
Lasse Collin e605c26636 Added resource files for the Windows build. 2009-02-10 21:48:05 +02:00
