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.

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.

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.

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.

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.

a6f43e6412 Use a GCC-specific #pragma instead of GCC-specific
-Wno-uninitialized to silence a bogus warning.

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.

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.

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).

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.

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

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.

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.
