2010-09-27Major man page updates.Lasse Collin7-641/+1435
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.
2010-09-26Fix the preset -3e.Lasse Collin1-0/+1
depth=0 was missing.
2010-09-23Add translations.bash and translation notes to README.Lasse Collin2-4/+192
translations.bash prints some messages from xz, which hopefully makes it a bit easier to test translations.

2010-09-10xz: Add a comment to translators about "literal context bits".Lasse Collin1-0/+4
2010-09-10xz: Multiple fixes.Lasse Collin12-187/+424
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.

2010-09-07Fix use of N_() and ngettext().Lasse Collin2-4/+4
I had somehow thought that N_() is usually used as shorthand for ngettext(). This also fixes a missing \n from a call to ngettext().

2010-09-04xz: Fix grammar.Lasse Collin1-2/+1
2010-09-04xz: Use lzma_lzma_preset() to initialize the options structure.Lasse Collin1-12/+2
2010-09-04Don't set lc=4 with --extreme.Lasse Collin1-1/+0
This should reduce the cases where --extreme makes compression worse. On the other hand, some other files may now benefit slightly less from --extreme.
2010-09-04xz: Minor improvements to --help and --long-help.Lasse Collin1-12/+12
2010-09-04Adjust memory limits in test_compress.shJonathan Nieder1-1/+1
Testing compression at level -4 now requires 48 MiB of free store at compression time and 5 MiB at decompression time. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>
2010-09-03xz: Make -vv show also decompressor memory usage.Lasse Collin1-0/+7
2010-09-03Tweak the compression presets -0 .. -5.Lasse Collin1-10/+19
"Extreme" mode might need some further tweaking still. Docs were not updated yet.
2010-09-03liblzma: Adjust default depth calculation for HC3 and HC4.Lasse Collin1-3/+4
It was 8 + nice_len / 4, now it is 4 + nice_len / 4. This allows faster settings at lower nice_len values, even though it seems that I won't use automatic depth calcuation with HC3 and HC4 in the presets.
2010-09-03xz: Make --help two lines shorter.Lasse Collin1-2/+5
At least for now, the --help option doesn't list any options that take arguments, so "Mandatory arguments to..." can be omitted.
2010-09-02xz: Make setting a preset override a custom filter chain.Lasse Collin1-0/+9
This is more logical behavior than ignoring preset level options once a custom filter chain has been specified.
2010-09-02xz: Always warn if adjusting dictionary size due to memlimit.Lasse Collin1-19/+9
2010-08-10Fix test_compress.sh.Lasse Collin1-3/+3
It broke when --memory option was removed from xzdec. Thanks to Jonathan Nieder.
2010-08-07Disable the memory usage limiter by default.Lasse Collin10-448/+373
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.
2010-08-06Add missing const to a global constant in xz.Lasse Collin2-2/+2

2010-07-13Add two simple example programs.Lasse Collin2-0/+242
Hopefully these help a bit when learning the basics of liblzma API. I plan to write detailed examples about both basic and advanced features with lots of comments, but these two examples are good have right now. The examples were written by Daniel Mealha Cabrita. Thanks.

2010-06-02Fix compiling with -Werror.Lasse Collin1-2/+2
2010-06-02Silence a bogus Valgrind warning.Lasse Collin1-1/+5
When using -O2 with GCC, it liked to swap two comparisons in one "if" statement. It's otherwise fine except that the latter part, which is seemingly never executed, got executed (nothing wrong with that) and then triggered warning in Valgrind about conditional jump depending on uninitialized variable. A few people find this annoying so do things a bit differently to avoid the warning.
2010-06-02Fix a Windows-specific FIXME in signal handling code.Lasse Collin3-13/+48
2010-06-02Adjust SA_RESTART workaround.Lasse Collin1-7/+7

2010-05-27Take Cygwin into account in some #if lines.Lasse Collin2-3/+3
This change is no-op, but good to have just in case for the future.
2010-05-27Remove references to the Subblock filter in xz and tests.Lasse Collin2-32/+0
Thanks to Jonathan Nieder.
2010-05-27Remove unused chunk_size.c.Lasse Collin1-67/+0
Thanks to Jonathan Nieder for the reminder.
2010-05-27Use my_min() instead of MIN() in src/xz/list.cJonathan Nieder1-1/+1
This should have been done in 920a69a8d8e4203c5edddd829d932130eac188ea.
2010-05-26Rename MIN() and MAX() to my_min() and my_max().Lasse Collin16-31/+31
This should avoid some minor portability issues.

2010-05-26Remove references to Subblock filter in debug/sync_flush.c.Lasse Collin1-13/+0
2010-05-26Better #error message.Lasse Collin1-2/+2
2010-05-26Remove the Subblock filter code for now.Lasse Collin19-2105/+4
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.
2010-05-16Split message_filters().Lasse Collin3-69/+134
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.
2010-05-14Omit lzma_restrict from the API headers.Lasse Collin3-21/+7
It isn't really useful so omitting it makes things shorter and slightly more readable.
2010-05-10Updated INSTALL.Lasse Collin1-5/+0
2010-05-10Updated THANKS.Lasse Collin1-0/+1
2010-05-10Updates to tuklib_physmem and tuklib_cpucores.Lasse Collin4-11/+141
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.
2010-04-12Show both elapsed time and estimated remaining time in xz -v.Lasse Collin2-48/+39
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.
2010-03-31Add a simple tip to faq.txt about tar and xz.Lasse Collin2-0/+7

2010-03-22Updated THANKS.Lasse Collin1-0/+1
2010-03-07Fix xzgrep to not break if filenames have spaces or quotes.Lasse Collin1-1/+1
Thanks to someone who reported the bug on IRC.
2010-03-07Treat all integer multiplier suffixes as base-2.Lasse Collin3-76/+67
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.
2010-03-07Consistently round up the memory usage limit in messages.Lasse Collin2-4/+8
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.
2010-03-07Change the default of --enable-assume-ram from 32 to 128 MiB.Lasse Collin2-8/+8
This is to allow files created with "xz -9" to be decompressed if the amount of RAM cannot be determined.
2010-03-07Increase the default memory usage limit on "low-memory" systems.Lasse Collin4-34/+80
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.
2010-03-06Updated THANKS.Lasse Collin1-0/+1
2010-03-06Fix missing initialization in lzma_strm_init().Lasse Collin1-0/+1
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 18c10c30d2833f394cd7bce0e6a821044b15832f 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.

2010-02-12Use __APPLE__ instead of __MACH__ in ASM files.Lasse Collin2-8/+8
This allows the files to work on HURD. Thanks to Jonathan Nieder.
2010-02-07Subtle change to liblzma Block handling API.Lasse Collin2-22/+20
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.
2010-02-02Fix wrong assertion.Lasse Collin1-2/+3
This was added in 455e68c030fde8a8c2f5e254c3b3ab9489bf3735.

2010-01-31Updated INSTALL.Lasse Collin1-26/+26
2010-01-31Revise the Windows build files.Lasse Collin6-645/+435
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.
2010-01-31Select the default integrity check type at runtime.Lasse Collin1-5/+14
Previously it was set statically to CRC64 or CRC32 depending on options passed to the configure script.
2010-01-31Improve displaying of the memory usage limit.Lasse Collin4-13/+45
2010-01-31Don't use uninitialized sigset_t.Lasse Collin1-10/+24
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.
2010-01-31Delay opening the destionation file and other fixes.Lasse Collin6-125/+157
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.
2010-01-29Add list.h to src/xz/Makefile.am.Lasse Collin1-0/+1
This should have been already in 0bc9eab243dee3be764b3530433a7fcdc3f7c6a1.

2010-01-26Minor comment fix.Lasse Collin1-2/+2
2010-01-24Add initial version of xz --list.Lasse Collin5-359/+668
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.
2010-01-24Add io_pread().Lasse Collin2-0/+42
It will be used by --list.
2010-01-24Set LC_NUMERIC=C when --robot is used.Lasse Collin1-0/+4
It is to ensure that floating point numbers will always have a dot as the decimal separator.

2010-01-17Updated windows/Makefile.Lasse Collin2-13/+27
Thanks to Dan Shechter for the patch. It is likely that windows/Makefile will be removed completely, because Autotols based build nowadays works well with both 32-bit and 64-bit MinGW (I just need to update the docs).
2010-01-15Update the xz man page to match the previous two commits.Lasse Collin1-6/+3
2010-01-13Don't read compressed data from a terminal or write itLasse Collin2-15/+13
to a terminal even if --force is specified. It just seems more reasonable this way. The new behavior matches bzip2. The old one matched gzip.
2010-01-13Don't compress or decompress special files unless writingLasse Collin1-5/+10
to stdout even if --force is used. --force will still enable compression of symlinks, but only in case they point to a regular file. The new way simply seems more reasonable. It matches gzip's behavior while the old one matched bzip2's behavior.

2010-01-12Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.Lasse Collin4-3/+55
This is untested but it will get tested soon and, if needed, fixed before 5.0.0. Thanks to Stuart Shelton.
2010-01-01Fix _memconfig() functions.Lasse Collin4-19/+20
This affects lzma_memusage() and lzma_memlimit_get().
2009-12-31Revised the Index handling code.Lasse Collin9-858/+1703
This breaks API and ABI but most apps are not affected since most apps don't use this part of the API. You will get a compile error if you are using anything that got broken. Summary of changes: - Ability to store Stream Flags, which are needed for random-access reading in multi-Stream files. - Separate function to set size of Stream Padding. - Iterator structure makes it possible to read the same lzma_index from multiple threads at the same time. - A lot faster code to locate Blocks. - Removed lzma_index_equal() without adding anything to replace it. I don't know what it should do exactly with the new features and what actually needs this function in the first place other than test_index.c, which now has its own code to compare lzma_indexes.
2009-12-31Remove c-format tag in cs.po.Lasse Collin1-1/+0
It was fixed in the C code earlier.

2009-12-09Remove redefinition of _(msgid) macro from lzmainfo.c.Lasse Collin1-7/+0
2009-12-09update po/.gitignoreJonathan Nieder1-6/+22
Since the *.gmo files are deleted by the maintainer-clean target, I assume they are not meant to be tracked. Also add the other files listed in the Makefile’s clean targets (stamp-poT, xz.po, xz.[12].po, *.new.po, xz.mo) to make sure they are not accidentally tracked. Most of these are intermediate files that would not appear unless a build is interrupted or fails. Split the list of untracked files by origin to make it easier to tell if files are missing in the future. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>
2009-12-09Always rely on GCC's auto-import on Windows.Lasse Collin1-7/+9
I understood that this is nicer, because then people don't need to worry about the LZMA_API_STATIC macro. Thanks to Charles Wilson and Keith Marshall.
2009-12-07Fix file_io.c on DOS-like systems.Lasse Collin1-0/+4
The problem was introduced when adding sparse file support in 465d1b0d6518c5d980f2db4c2d769f9905bdd902. Thanks to Charles Wilson.

2009-11-25Add missing error check to coder.c.Lasse Collin1-9/+11
With bad luck this could cause a segfault due to reading (but not writing) past the end of the buffer.
2009-11-25Fix bugs in lzma_index_read() and lzma_index_cat().Lasse Collin2-14/+44
lzma_index_read() didn't skip over Stream Padding if it was the first record in the Index. lzma_index_cat() didn't combine small Indexes correctly. The test suite was updated to check for these bugs. These bugs didn't affect the xz command line tool or most users of liblzma in any way.
2009-11-25Index decoder fixes.Lasse Collin2-17/+32
The Index decoder code didn't perfectly match the API docs, which said that *i will be set to point to the decoded Index only after decoding has succeeded. The docs were a bit unclear too. Now the decoder will initially set *i to NULL. *i will be set to point to the decoded Index once decoding has succeeded. This simplifies applications too, since it avoids dangling pointers.
2009-11-25Create sparse files by default when decompressing intoLasse Collin6-56/+272
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.

2009-11-22Add missing consts to pointer casts.Lasse Collin2-4/+5
2009-11-22Enable assembler code only if it is known to workLasse Collin1-14/+12
on that operating system. I'm too lazy to think how to make a good Autoconf test for this and it's not that important anyway. No longer define HAVE_ASM_X86 or HAVE_ASM_X86_64. Inline assembler (if any) is used if a macro like __i386__ or __x86_64__ is defined.
2009-11-22Make fastpos.h use tuklib_integer.h instead of bsr.hLasse Collin3-65/+1
when --enable-small has been specified.
2009-11-22Update tuklib_integer.h with bit scan functions.Lasse Collin1-8/+181
Thanks to Joachim Henke for the original patch.
2009-11-20Update tuklib_cpucores.m4 and tuklib_physmem.m4 from tuklib,Lasse Collin3-36/+61
which now use AC_CACHE_CHECK. Using the cache variable, configure now warns if there is no method to detect the amount of RAM and recommends using --enable-assume-ram.
2009-11-16Add support for --info-memory and --robot to xz.Lasse Collin6-55/+133
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.
2009-11-15Fix wrong indentation caused by incorrect settingsLasse Collin3-13/+13
in the text editor.
2009-11-15Add lzma_physmem().Lasse Collin10-11/+88
I had hoped to keep liblzma as purely a compression library as possible (e.g. file I/O will go into a different library), but it seems that applications linking agaisnt liblzma need some way to determine the memory usage limit, and knowing the amount of RAM is one reasonable way to help making such decisions. Thanks to Jonathan Nieder for the original patch.

2009-11-14Fix a design error in liblzma API.Lasse Collin20-118/+273
Originally the idea was that using LZMA_FULL_FLUSH with Stream encoder would read the filter chain from the same array that was used to intialize the Stream encoder. Since most apps wouldn't use LZMA_FULL_FLUSH, most apps wouldn't need to keep the filter chain available after initializing the Stream encoder. However, due to my mistake, it actually required keeping the array always available. Since setting the new filter chain via the array used at initialization time is not a nice way to do it for a couple of reasons, this commit ditches it and introduces lzma_filters_update(). This new function replaces also the "persistent" flag used by LZMA2 (and to-be-designed Subblock filter), which was also an ugly thing to do. Thanks to Alexey Tourbin for reminding me about the problem that Stream encoder used to require keeping the filter chain allocated.
2009-10-17Fix wrong function name in the previous commit.Lasse Collin2-2/+2
It was meant to be lzma_filters_copy(), not lzma_filters_dup().
2009-10-17Add lzma_filters_copy().Lasse Collin2-0/+113
This will be needed internally by liblzma once I fix a design mistake in the encoder API. This function may be useful to applications too so it's good to export it.
2009-10-16Escape dashes in xzmore.1Jonathan Nieder1-2/+2
A minus sign is larger, easier to see in a printout, and more likely to use the same glyph as ASCII hyphen-minus in a terminal than a hyphen. Since broken manual pagers do not find hyphens when the user searches for a hyphen-minus, minus signs are also easier to search for. So use minus signs instead of hyphens to render sample terminal output.
2009-10-16Mention --check=none in --long-help. It was already inLasse Collin1-1/+1
the man page though. Thanks to Jim Meyering for noticing this.
2009-10-04Use a tuklib module for integer handling.Lasse Collin28-333/+467
This replaces bswap.h and integer.h. The tuklib module uses <byteswap.h> on GNU, <sys/endian.h> on *BSDs and <sys/byteorder.h> on Solaris, which may contain optimized code like inline assembly.
2009-10-02Add support for --enable-assume-ram=SIZE.Lasse Collin4-6/+46
2009-10-02Use unaligned access (if possible) on both endiannessesLasse Collin1-2/+2
in lz_encoder_hash.h.
2009-10-02Make liblzma produce the same output on both endiannesses.Lasse Collin6-14/+128
Seems that it is a problem in some cases if the same version of XZ Utils produces different output on different endiannesses, so this commit fixes that problem. The output will still vary between different XZ Utils versions, but I cannot avoid that for now. This commit bloatens the code on big endian systems by 1 KiB, which should be OK since liblzma is bloated already. ;-)

2009-09-19Various changes.Lasse Collin37-434/+768
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.

the function call succeeded. NetBSD 4.0 returns positive values on success, but NetBSD Current and FreeBSD return zero. OpenBSD's man page doesn't tell what sysctl() returns on success. All these BSDs return -1 on error. Thanks to Robert Elz and Thomas Klausner.

2009-08-29Use even more hackish way to support thousand separators.Lasse Collin1-11/+25
Seems that in addition on Windows and DOS, also OpenBSD lacks support for %'d style printf() format strings. So far that is the only modern POSIX-like system I know with this problem, but after this hack, the thousand separator shouldn't be a problem on any system. Maybe testing if a format string like %'d produces reasonable output is invoking undefined behavior on some systems, but so far all the problematic systems I've tried just print the raw format string (e.g. %'d prints 'd). Maybe Autoconf test would have been better, but this hack works also for cross-compilation, and avoids recompilation in case the system libc starts to support the thousand separator.
