Thanks to Jonathan Nieder.
2010-09-28Fix accomodate -> accommodate on the xz man page.Lasse Collin1-1/+1
2010-09-27Major man page updates.Lasse Collin1-598/+1366
Lots of content was updated on the xz man page. Technical improvements: - Start a new sentence on a new line. - Use fairly short lines. - Use constant-width font for examples (where supported). - Some minor cleanups. Thanks to Jonathan Nieder for some language fixes.
2010-08-07Disable the memory usage limiter by default.Lasse Collin1-126/+215
For several people, the limiter causes bigger problems that it solves, so it is better to have it disabled by default. Those who want to have a limiter by default need to enable it via the environment variable XZ_DEFAULTS. Support for environment variable XZ_DEFAULTS was added. It is parsed before XZ_OPT and technically identical with it. The intended uses differ quite a bit though; see the man page. The memory usage limit can now be set separately for compression and decompression using --memlimit-compress and --memlimit-decompress. To set both at once, -M or --memlimit can be used. --memory was retained as a legacy alias for --memlimit for backwards compatibility. The semantics of --info-memory were changed in backwards incompatible way. Compatibility wasn't meaningful due to changes in the memory usage limiter functionality. The memory usage limiter info is no longer shown at the bottom of xz --long -help. The memory usage limiter support for removed completely from xzdec. xz's man page was updated to match the above changes. Various unrelated fixes were also made to the man page.

- Concatenating .xz files and padding - List mode - Robot mode - A few examples (but many more are needed)
2010-03-07Treat all integer multiplier suffixes as base-2.Lasse Collin1-20/+28
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.
2010-03-07Increase the default memory usage limit on "low-memory" systems.Lasse Collin1-6/+15
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.
2010-02-12Collection of language fixes to comments and docs.Lasse Collin1-8/+8
Thanks to Jonathan Nieder.
2010-01-15Update the xz man page to match the previous two commits.Lasse Collin1-6/+3
2009-11-25Create sparse files by default when decompressing intoLasse Collin1-0/+11
a regular file. Sparse file creation can be disabled with --no-sparse. I don't promise yet that the name of this option won't change before 5.0.0. It's possible that the code, that checks when it is safe to use sparse output on stdout, is not good enough, and a more flexible command line option is needed to configure sparse file handling.
2009-11-16Add support for --info-memory and --robot to xz.Lasse Collin1-4/+36
Currently --robot works only with --info-memory and --version. --help and --long-help work too, but --robot has no effect on them. Thanks to Jonathan Nieder for the original patches.
