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 1754b7e03e Portability improvement to version.sh. 2009-07-08 23:05:29 +03:00
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.

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().

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.

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.
