Lasse Collin 98a4856a6e Remove references to Subblock filter in debug/sync_flush.c. 2010-05-26 10:28:54 +03:00
Lasse Collin 703d2c33c0 Better #error message. 2010-05-26 10:16:57 +03:00
Lasse Collin d8a55c48b3 Remove the Subblock filter code for now.
The spec isn't finished and the code didn't compile anymore.
It won't be included in XZ Utils 5.0.0. It's easy to get it
back once the spec is done.

Lasse Collin b6377fc990 Split message_filters().
message_filters_to_str() converts the filter chain to
a string. message_filters_show() replaces the original
message_filters().

uint32_to_optstr() was also added to show the dictionary
size in nicer format when possible.

Lasse Collin d9986db782 Omit lzma_restrict from the API headers.
It isn't really useful so omitting it makes things
shorter and slightly more readable.

Lasse Collin 6548e30465 Updates to tuklib_physmem and tuklib_cpucores.
Don't use #error to generate compile error, because some
compilers actually don't take it as an error. This fixes
tuklib_physmem on IRIX.

Fix incorrect error check for sysconf() return values.

Add AIX, HP-UX, and Tru64 specific code to detect the
amount RAM.

Add HP-UX specific code to detect the number of CPU cores.

Thanks a lot to Peter O'Gorman for initial patches,
testing, and debugging these fixes.

Lasse Collin a290cfee3e Show both elapsed time and estimated remaining time in xz -v.
The extra space for showing both has been taken from the
sizes field. If the sizes grow big, bigger units than MiB
will be used. It makes it slightly difficult to see that
progress is still happening with huge files, but it should
be OK in practice.

Thanks to Trent W. Buck for <http://bugs.debian.org/574583>
and Jonathan Nieder for suggestions how to fix it.

Thanks to someone who reported the bug on IRC.

Lasse Collin cf38da00a1 Treat all integer multiplier suffixes as base-2.
Originally both base-2 and base-10 were supported, but since
there seems to be little need for base-10 in XZ Utils, treat
everything as base-2 and also be more relaxed about the case
of the first letter of the suffix. Now xz will accept e.g.
KiB, Ki, k, K, kB, and KB, and interpret them all as 1024. The
recommended spelling of the suffixes are still KiB, MiB, and GiB.

Lasse Collin 00fc1211ae Consistently round up the memory usage limit in messages.
It still feels a bit wrong to round 1 byte to 1 MiB but
at least it is now done consistently so that the same
byte value is always rounded the same way to MiB.

Lasse Collin 9886d436ff Change the default of --enable-assume-ram from 32 to 128 MiB.
This is to allow files created with "xz -9" to be decompressed
if the amount of RAM cannot be determined.
2010-03-07 13:34:34 +02:00
Lasse Collin 2672bcc9f8 Increase the default memory usage limit on "low-memory" systems.
Previously the default limit was always 40 % of RAM. The
new limit is a little bit more complex:

  - If 40 % of RAM is at least 80 MiB, 40 % of RAM is used
    as the limit.

  - If 80 % of RAM is over 80 MiB, 80 MiB is used as the limit.

  - Otherwise 80 % of RAM is used as the limit.

This should make it possible to decompress files created with
"xz -9" on more systems. Swapping is generally more expected
on systems with less RAM, so higher default limit on them
shouldn't cause too bad surprises in terms of heavy swapping.
Instead, the higher default limit should reduce the number of
bad surprises when it used to prevent decompression of files
created with "xz -9". The DoS prevention system shouldn't be
a DoS itself.

Note that even with the new default limit, a system with 64 MiB
RAM cannot decompress files created with "xz -9" without user
overriding the limit. This should be OK, because if xz is going
to need more memory than the system has RAM, it will run very
very slowly and thus it's good that user has to override the limit
in that case.

Lasse Collin d0d1c51aea Fix missing initialization in lzma_strm_init().
With bad luck, lzma_code() could return LZMA_BUF_ERROR
when it shouldn't.

This has been here since the early days of liblzma.
It got triggered by the modifications made to the xz
tool in commit 18c10c30d2
but only when decompressing .lzma files. Somehow I managed
to miss testing that with Valgrind earlier.

This fixes <http://bugs.gentoo.org/show_bug.cgi?id=305591>.
Thanks to Rafał Mużyło for helping to debug it on IRC.

Lasse Collin 6b50c9429b Use __APPLE__ instead of __MACH__ in ASM files.
This allows the files to work on HURD.

Thanks to Jonathan Nieder.

Lasse Collin 6503fde658 Subtle change to liblzma Block handling API.
lzma_block.version has to be initialized even for
lzma_block_header_decode(). This way a future version
of liblzma won't allocate memory in a way that an old
application doesn't know how to free it.

The subtlety of this change is that all current apps
using lzma_block_header_decode() will keep working for
now, because the only possible version value is zero,
and lzma_block_header_decode() unconditionally sets the
version to zero even now. Unless fixed, these apps will
break in the future if a new version of the Block options
is ever needed.

xz --force accepted symlinks, but didn't remove
them after successful compression. Instead, an error
message was displayed.

Lasse Collin 2901a8e7e8 Updated INSTALL. 2010-01-31 23:31:14 +02:00
Lasse Collin 8884e16864 Revise the Windows build files.
The old Makefile + config.h was deleted, because it
becomes outdated too easily and building with the
Autotools based build system works fine even on Windows.

windows/build.sh hasn't got much testing, but it should
work to build 32-bit x86 and x86-64 versions of XZ Utils
using MSYS, MinGW or MinGW-w32, and MinGW-w64.

windows/INSTALL-Windows.txt describes what packages are
needed and how to install them.

windows/README-Windows.txt is a readme file for the binary
package that build.sh hopefully builds.

There are no instructions about using Autotools for now,
so those using a git snapshot may want to run
"autoreconf -fi && ./configure && make mydist" on a UN*X
box and then copy the resulting .tar.gz to a Windows.

Lasse Collin 34eb5e201d Select the default integrity check type at runtime.
Previously it was set statically to CRC64 or CRC32
depending on options passed to the configure script.

Lasse Collin 96a4f840e3 Improve displaying of the memory usage limit. 2010-01-31 18:17:50 +02:00
Lasse Collin b3cc4d8edd Don't use uninitialized sigset_t.
If signal handlers haven't been established, then it's
useless to try to block them, especially since the sigset_t
used for blocking hasn't been initialized yet.
2010-01-31 12:53:56 +02:00
Lasse Collin 231c3c7098 Delay opening the destionation file and other fixes.
The opening of the destination file is now delayed a little.
The coder is initialized, and if decompressing, the memory
usage of the first Block compared against the memory
usage limit before the destination file is opened. This
means that if --force was used, the old "target" file won't
be deleted so easily when something goes wrong very early.
Thanks to Mark K for the bug report.

The above fix required some changes to progress message
handling. Now there is a separate function for setting and
printing the filename. It is used also in list.c.

list_file() now handles stdin correctly (gives an error).

A useless check for user_abort was removed from file_io.c.
2010-01-31 12:01:54 +02:00
Lasse Collin 0dbd0641db Add list.h to src/xz/Makefile.am.

Lasse Collin 0bc9eab243 Add initial version of xz --list.
This is a bit rough but should be useful for basic things.
Ideas (with detailed examples) about the output format are
welcome.

The output of --robot --list is not necessarily stable yet,
although I don't currently have any plans about changing it.

The man page hasn't been updated yet.

It will be used by --list.
