2010-09-10	xz: Multiple fixes.	Lasse Collin	1	-3/+7
	The code assumed that printing numbers with thousand separators and decimal points would always produce only US-ASCII characters. This was used for buffer sizes (with snprintf(), no overflows) and aligning columns of the progress indicator and --list. That assumption was wrong (e.g. LC_ALL=fi_FI.UTF-8 with glibc), so multibyte character support was added in this commit. The old way is used if the operating system doesn't have enough multibyte support (e.g. lacks wcwidth()). The sizes of buffers were increased to accomodate multibyte characters. I don't know how big they should be exactly, but they aren't used for anything critical, so it's not too bad. If they still aren't big enough, I hopefully get a bug report. snprintf() takes care of avoiding buffer overflows. Some static buffers were replaced with buffers allocated on stack. double_to_str() was removed. uint64_to_str() and uint64_to_nicestr() now share the static buffer and test for thousand separator support. Integrity check names "None" and "Unknown-N" (2 <= N <= 15) were marked to be translated. I had forgot these, plus they wouldn't have worked correctly anyway before this commit, because printing tables with multibyte strings didn't work. Thanks to Marek Černocký for reporting the bug about misaligned table columns in --list output.
2010-08-07	Disable the memory usage limiter by default.	Lasse Collin	1	-4/+0
	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.
2010-06-01	Rename message_filters_get() to message_filters_to_str().	Lasse Collin	1	-1/+1

2010-05-16	Split message_filters().	Lasse Collin	1	-1/+13
	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.
2010-02-12	Collection of language fixes to comments and docs.	Lasse Collin	1	-1/+1
	Thanks to Jonathan Nieder.
2010-01-31	Delay opening the destionation file and other fixes.	Lasse Collin	1	-9/+20
	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.
2010-01-24	Some improvements to printing sizes in xz.	Lasse Collin	1	-0/+4

2009-11-16	Add support for --info-memory and --robot to xz.	Lasse Collin	1	-0/+4
	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.
2009-09-19	Various changes.	Lasse Collin	1	-4/+4
	Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	1	-10/+3
	Some minor documentation cleanups were made at the same time.
2009-02-22	Fixes to progress message handling in xz:	Lasse Collin	1	-10/+18
	- 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.
2009-02-05	Various code cleanups the the xz command line tool.	Lasse Collin	1	-6/+0
	It now builds with MinGW.
2008-12-17	xz message handling improvements	Lasse Collin	1	-1/+6

2008-11-19	Renamed lzma to xz and lzmadec to xzdec. We create symlinks	Lasse Collin	1	-0/+132
	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.
