Lasse Collin eed9953732 Look for full command names instead of substrings
like "un", "cat", and "lz" when determining if
xz is run as unxz, xzcat, lzma, unlzma, or lzcat.

This is to ensure that if xz is renamed (e.g. via
--program-transform-name), it doesn't so easily
work in wrong mode.

Lasse Collin 3bdb53792c Remove --force from xzdec.
It was ignored for compatibility with xz, but now that
--decompress --stdout --force copies unrecognized files
as is to stdout, simply ignoring --force in xzdec would
be wrong. xzdec will not support copying unrecognized
data as is to stdout, so it cannot support --force.
2009-07-08 22:50:16 +03:00
Lasse Collin 5f16ef4abf Use sed instead of $(SED) so that we don't need to
use AC_PROG_SED. We don't do anything fancy with sed,
so this should work OK. libtool 2.2 sets SED but 1.5
doesn't, so $(SED) happened to work when using libtool 2.2.

Lasse Collin 96e4b257e1 Major update to the xzgrep and other scripts based on
the latest versions found from gzip CVS repository.

configure will try to find a POSIX shell to be used by
the scripts. This should ease portability on systems
which have pre-POSIX /bin/sh.

xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files.
xzmore and xzless support only .xz and .lzma files.

The name of the xz executable used in these scripts is
now correct even if --program-transform-name has been used.

Lasse Collin 25cc7a6e8c Use @PACKAGE_HOMEPAGE@ in liblzma.pc.in. 2009-07-05 19:26:53 +03:00
Lasse Collin 18c10c30d2 Make "xz --decompress --stdout --force" copy unrecognized
files as is to standard output.

This feature is needed to be more compatible with gzip's
behavior. This was more complicated to implement than it
sounds, because the way liblzma is able to return errors with
files of only a few bytes in size. xz now has its own file
type detection code and no longer uses lzma_auto_decoder().
2009-07-04 00:40:44 +03:00
Lasse Collin 0a289c01ac Define PACKAGE_HOMEPAGE in configure.ac and use it in
xz and xzdec.

Use also PACKAGE_NAME instead of hardcoding "XZ Utils".

Lasse Collin f42ee98166 Build system fixes
Don't use libtool convenience libraries to avoid recently
discovered long-standing subtle but somewhat severe bugs
in libtool (at least 1.5.22 and 2.2.6 are affected). It
was found when porting XZ Utils to Windows
<http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html>
but the problem is significant also e.g. on GNU/Linux.

Unless --disable-shared is passed to configure, static
library built from a set of convenience libraries will
contain PIC objects. That is, while libtool builds non-PIC
objects too, only PIC objects will be used from the
convenience libraries. On 32-bit x86 (tested on mobile XP2400+),
using PIC instead of non-PIC makes the decompressor 10 % slower
with the default CFLAGS.

So while xz was linked against static liblzma by default,
it got the slower PIC objects unless --disable-shared was
used. I tend develop and benchmark with --disable-shared
due to faster build time, so I hadn't noticed the problem
in benchmarks earlier.

This commit also adds support for building Windows resources
into liblzma and executables.
2009-06-30 17:09:57 +03:00

Lasse Collin da0af22e4b Updated comments to match renamed files. 2009-06-26 21:00:35 +03:00
Lasse Collin 65014fd211 Rename process.[hc] to coder.[hc] and io.[hc] to file_io.[hc]
to avoid problems on systems with system headers with those
names.
2009-06-26 20:49:54 +03:00
Lasse Collin 5e1257466d Rename process_file() to coder_run(). 2009-06-26 20:43:36 +03:00
Lasse Collin cad62551c5 Ugly hack to make it possible to use the thousand separator
format character with snprintf() on POSIX systems but not
on non-POSIX systems and still keep xgettext working.
2009-06-26 20:36:45 +03:00
Lasse Collin 390a640856 Basic support for building with Cygwin and MinGW using
the Autotools based build system. It's not good yet, more
fixes will follow.
2009-06-26 15:37:53 +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.
2009-06-26 14:47:31 +03:00
Lasse Collin b317b218e2 Support HW_PHYSMEM64 2009-06-24 20:14:10 +03:00
Lasse Collin ae82dde5d9 Cast a char argument to isspace() to unsigned char. 2009-06-24 13:01:59 +03:00
Lasse Collin 8ed156ce89 Added xzdec man page. 2009-06-04 23:42:12 +03:00
Lasse Collin f6df39afaa Harmonized xzdec --memory with xz --memory and made
minor cleanups.
2009-06-04 23:26:47 +03:00
Lasse Collin 1774f27c61 Fix purporse -> purpose. Thanks to Andrew Dudman.
Released .xz spec 1.0.2 due to this fix too.
2009-06-04 22:59:55 +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 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 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
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).
2009-04-15 14:13:38 +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.
2009-04-10 11:17:02 +03:00
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 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.
2009-02-22 18:52:49 +02:00
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.
2009-02-14 00:45:29 +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.
2009-02-13 18:00:03 +02:00
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.
2009-02-13 17:29:02 +02:00
Lasse Collin a3bbbe05d3 Let the user specify custom CFLAGS on the make command
line. Previously custom CFLAGS worked only when they were
passed to configure.
2009-02-09 14:54:31 +02:00
Lasse Collin 53f7598998 Fix aliasing issue in physmem.h. 2009-02-08 21:35:11 +02:00
Lasse Collin 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.
2009-02-08 18:24:50 +02:00
Lasse Collin ae1ad9af54 Make "xz --force" to write to terminal as the error
message suggests.
2009-02-08 18:17:05 +02:00
Lasse Collin 79e25eded4 Support both slash and backslash as path component
separator on Windows when parsing argv[0].
2009-02-08 10:37:50 +02:00
Lasse Collin 880c330938 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 21:17:07 +02:00
Lasse Collin bd7ca1dad5 Assume 32 MiB of RAM on unsupported operating systems like
the comment in hardware.c already said.
2009-02-07 17:07:52 +02:00
Lasse Collin bfd91198e4 Support LZMA_API_STATIC in assembler files to
avoid __declspec(dllexport) equivalent.
2009-02-07 15:55:47 +02:00
Lasse Collin 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.
2009-02-07 11:11:50 +02:00
Lasse Collin 75905a9afc Various code cleanups the the xz command line tool.
It now builds with MinGW.
2009-02-05 09:12:57 +02:00
Lasse Collin d0c0b9e94e Another utime() fix. 2009-02-03 12:15:17 +02:00
Lasse Collin ccf92a29e8 Fix wrong filename argument for utime() and utimes().
This doesn't affect most systems, since most systems
have better functions available.
2009-02-03 10:41:11 +02:00
Lasse Collin 99c1c2abfa 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
Lasse Collin 22a0c6dd94 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.
2009-02-02 20:14:03 +02:00
Lasse Collin 8dd7b6052e Fix a bug in lzma_block_buffer_decode(), although this
function should be rewritten anyway.
2009-02-01 22:40:35 +02:00
Lasse Collin 55fd41431e Added initial version of raw buffer-to-buffer coding
functions, and cleaned up filter.h API header a little.
May be very buggy, not tested yet.
2009-02-01 22:39:07 +02:00
Lasse Collin 3e54ecee5c Fix missing newlines in xzdec.c. 2009-02-01 00:11:20 +02:00
Lasse Collin d64ca34f1b Use __cdecl also for function pointers in liblzma API when
on Windows.
2009-02-01 00:10:07 +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.
2009-01-31 11:01:48 +02:00
Lasse Collin d9993fcb4d Use _WIN32 instead of WIN32 in xzdec.c to test if compiling on Windows. 2009-01-31 10:13:09 +02:00

beginning of the line.
2009-01-31 10:02:52 +02:00
Lasse Collin 4ab7601091 Add support for using liblzma headers in MSVC, which has no
stdint.h or inttypes.h.
2009-01-31 09:55:05 +02:00
Lasse Collin b2172cf823 Fix # -> ## in a macro in lzma.h. 2009-01-31 08:49:54 +02:00
Lasse Collin f54bcf6f80 Remove dangling crc64_init.c. 2009-01-30 00:29:58 +02:00
Lasse Collin 3241317093 Fix uninitialized variables in alone_decoder.c. This bug was
triggered by the previous commit, since these variables were
not used by anything before support for a preset dictionary.
2009-01-28 08:43:26 +02:00
Lasse Collin f76e39cf93 Added initial support for preset dictionary for raw LZMA1
and LZMA2. It is not supported by the .xz format or the xz
command line tool yet.
2009-01-27 18:36:05 +02:00
Lasse Collin 449b8c832b Regenerate the CRC tables without trailing blanks. 2009-01-26 20:09:17 +02:00

Lasse Collin 2c5fe958e4 Fix a dumb bug in Block decoder, which made it return
LZMA_DATA_ERROR with valid data. The bug was added in
e114502b2b.
2009-01-25 01:35:56 +02:00
Lasse Collin c81f13ff29 Added lzma_stream_buffer_decode() and made minor cleanups. 2009-01-23 22:27:50 +02:00
Lasse Collin 0b3318661c Fix a comment. 2009-01-22 12:53:33 +02:00

Lasse Collin 4810b6bc25 Move some LZMA2 constants to lzma2_encoder.h so that they
can be used outside lzma2_encoder.c.
2009-01-19 14:00:33 +02:00
Lasse Collin 00be5d2e09 Remove dead code. 2009-01-19 13:52:36 +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.
2009-01-17 14:24:25 +02:00
Lasse Collin 8286a60b8f Use pthread_sigmask() instead of sigprocmask() when pthreads
are enabled.
2009-01-07 18:41:15 +02:00
Lasse Collin 4fd43cb3a9 Bumped version to 4.999.8beta right after the release
of 4.999.7beta.
2008-12-31 20:01:00 +02:00
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.
2008-12-31 16:29:39 +02:00
Lasse Collin 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
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 050eb14d29 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.

Lasse Collin 4820f10d0f Some xz command line tool improvements. 2008-12-27 19:30:19 +02:00
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.

Lasse Collin 4d00652e75 Updated Makefile.am that was missing from the previous commit. 2008-12-18 13:42:52 +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 1ea9e7f15a Added preset=NUM to --lzma1 and --lzma2. This makes it easy
to take a preset as a template and modify it a little.
2008-12-10 01:23:58 +02:00
Lasse Collin 6efa2d80d4 Make the memusage functions of LZMA1 and LZMA2 encoders
to validate the filter options. Add missing validation
to LZMA2 encoder when options are changed in the middle
of encoding.
2008-12-09 17:41:49 +02:00
Lasse Collin ef7890d564 In command line tool, take advantage of memusage calculation's
ability to also validate the filter chain and options (not
implemented yet for all filters).

part of 656ec87882.
2008-12-01 22:55:18 +02:00
Lasse Collin cd70801520 LZMA2 decoder cleanups. Make it require new LZMA properties
also in the first LZMA chunk after a dictionary reset in
uncompressed chunk.
2008-12-01 22:50:28 +02:00
Lasse Collin 656ec87882 Added lzma_delta_coder_memusage() which also validates
the options.
2008-12-01 16:30:11 +02:00
Lasse Collin c7007ddf06 Tested using COLUMNS environment variable to avoid broken
progress indicator but since COLUMNS isn't usually available,
the code was left commented out.

files and lzmadec only .lzma files.
2008-11-20 18:05:52 +02:00
Lasse Collin 86a0ed8f01 Minor cleanups to xzdec. 2008-11-20 11:01:29 +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
