2014-12-21Bump version and soname for 5.0.8.Lasse Collin2-2/+2
2014-12-17Add support for AmigaOS/AROS to tuklib_physmem().Lasse Collin1-0/+7
Thanks to Fredrik Wikstrom.
2014-12-17xzgrep: Avoid passing both -q and -l to grep.Lasse Collin1-2/+4
The behavior of grep -ql varies: - GNU grep behaves like grep -q. - OpenBSD grep behaves like grep -l. POSIX doesn't make it 100 % clear what behavior is expected. Anyway, using both -q and -l at the same time makes no sense so both options simply should never be used at the same time. Thanks to Christian Weisgerber.

2014-09-20liblzma: Fix invalid Libs.private value in liblzma.pc.Lasse Collin1-1/+1
2014-09-20liblzma: Fix a portability problem in Makefile.am.Lasse Collin1-1/+1
POSIX supports $< only in inference rules (suffix rules). Using it elsewhere is a GNU make extension and doesn't work e.g. with OpenBSD make. Thanks to Christian Weisgerber for the patch.

2014-09-09xzgrep: exit 0 when at least one file matches.Lasse Collin1-2/+13
Mimic the original grep behavior and return exit_success when at least one xz compressed file matches given pattern. Original bugreport: https://bugzilla.redhat.com/show_bug.cgi?id=1108085 Thanks to Pavel Raiskup for the patch.
2014-04-26Build: Fix the combination of --disable-xzdec --enable-lzmadec.Lasse Collin1-1/+9
In this case "make install" could fail if the man page directory didn't already exist at the destination. If it did exist, a dangling symlink was created there. Now the link is omitted instead. This isn't the best fix but it's better than the old behavior.
2014-04-26xz: Rename a variable to avoid a namespace collision on Solaris.Lasse Collin1-5/+7
I don't know the details but I have an impression that there's no problem in practice if using GCC since people have built xz with GCC (without patching xz), but renaming the variable cannot hurt either. Thanks to Mark Ashley.
2014-04-26xz: Fix a comment.Lasse Collin1-2/+2
2014-04-26liblzma: Avoid C99 compound literal arrays.Lasse Collin1-3/+5
MSVC 2013 doesn't like them. Maybe they aren't so good for readability either since many aren't used to them.
2014-04-26liblzma: Remove a useless C99ism from sha256.c.Lasse Collin1-1/+1
Unsurprisingly it makes no difference in compiled output.
2014-04-26xz: Fix use of wrong variable.Lasse Collin1-1/+1
Since the only call to suffix_set() uses optarg as the argument, fixing this bug doesn't change the behavior of the program.

2014-04-26liblzma: Document the need for block->check for lzma_block_header_decode().Lasse Collin1-0/+3
Thanks to Tomer Chachamu.
2014-04-26Build: Create liblzma.pc in a src/liblzma/Makefile.am.Lasse Collin1-0/+20
Previously it was done in configure, but doing that goes against the Autoconf manual. Autoconf requires that it is possible to override e.g. prefix after running configure and that doesn't work correctly if liblzma.pc is created by configure. A potential downside of this change is that now e.g. libdir in liblzma.pc is a standalone string instead of being defined via ${prefix}, so if one overrides prefix when running pkg-config the libdir won't get the new value. I don't know if this matters in practice. Thanks to Vincent Torri.
2013-06-30Man pages: Use similar syntax for synopsis as in xz.larhzu/v5.0.5Lasse Collin3-10/+10
The man pages of lzmainfo, xzmore, and xzdec had similar constructs as the man page of xz had before the commit eb6ca9854b8eb9fbf72497c1cf608d6b19d2d494. Eric S. Raymond didn't mention these man pages in his bug report, but it's nice to be consistent.

2013-06-28xz: Fix return value type in io_write_buf().Lasse Collin1-1/+1
It didn't affect the behavior of the code since -1 becomes true anyway.
2013-06-28xz: Remove an outdated NetBSD-specific comment.Lasse Collin1-4/+0
Nowadays errno == EFTYPE is documented in open(2).
2013-06-28xz: Fix error detection of fcntl(fd, F_SETFL, flags) calls.Lasse Collin1-4/+4
POSIX says that fcntl(fd, F_SETFL, flags) returns -1 on error and "other than -1" on success. This is how it is documented e.g. on OpenBSD too. On Linux, success with F_SETFL is always 0 (at least accorinding to fcntl(2) from man-pages 3.51).
2013-06-28xz: Fix use of wrong variable in a fcntl() call.Lasse Collin1-11/+13
Due to a wrong variable name, when writing a sparse file to standard output, *all* file status flags were cleared (to the extent the operating system allowed it) instead of only clearing the O_APPEND flag. In practice this worked fine in the common situations on GNU/Linux, but I didn't check how it behaved elsewhere. The original flags were still restored correctly. I still changed the code to use a separate boolean variable to indicate when the flags should be restored instead of relying on a special value in stdout_flags.
2013-06-26xz: Check the value of lzma_stream_flags.version in --list.Lasse Collin1-0/+14
It is a no-op for now, but if an old xz version is used together with a newer liblzma that supports something new, then this check becomes important and will stop the old xz from trying to parse files that it won't understand.
2013-06-26xz: Validate Uncompressed Size from Block Header in list.c.Lasse Collin1-1/+13
This affects only "xz -lvv". Normal decompression with xz already detected if Block Header and Index had mismatched Uncompressed Size fields. So this just makes "xz -lvv" show such files as corrupt instead of showing the Uncompressed Size from Index.
2013-06-26xz: Make the man page more friendly to doclifter.Lasse Collin1-3/+4
Thanks to Eric S. Raymond.
2013-06-26xz: A couple of man page fixes.Lasse Collin1-12/+23
Now the interaction of presets and custom filter chains is described correctly. Earlier it contradicted itself. Thanks to DevHC who reported these issues on IRC to me on 2012-12-14.
2013-06-26xz: Fix interaction between preset and custom filter chains.Lasse Collin1-14/+21
There was somewhat illogical behavior when --extreme was specified and mixed with custom filter chains. Before this commit, "xz -9 --lzma2 -e" was equivalent to "xz --lzma2". After it is equivalent to "xz -6e" (all earlier preset options get forgotten when a custom filter chain is specified and the default preset is 6 to which -e is applied). I find this less illogical. This also affects the meaning of "xz -9e --lzma2 -7". Earlier it was equivalent to "xz -7e" (the -e specified before a custom filter chain wasn't forgotten). Now it is "xz -7". Note that "xz -7e" still is the same as "xz -e7". Hopefully very few cared about this in the first place, so pretty much no one should even notice this change. Thanks to Conley Moorhous.
2013-06-26xz: Change size_t to uint32_t in a few places.Lasse Collin2-4/+4
2013-06-26xzdec: Improve the --help message.Lasse Collin1-5/+5
The options are now ordered in the same order as in xz's help message. Descriptions were added to the options that are ignored. I left them in parenthesis even if it looks a bit weird because I find it easier to spot the ignored vs. non-ignored options from the list that way.
2013-04-05xzgrep: make the '-h' option to be --no-filename equivalentJeff Bastian1-1/+1
* src/scripts/xzgrep.in: Accept the '-h' option in argument parsing.
2013-04-05liblzma: Be less picky in lzma_alone_decoder().Lasse Collin3-11/+18
To avoid false positives when detecting .lzma files, rare values in dictionary size and uncompressed size fields were rejected. They will still be rejected if .lzma files are decoded with lzma_auto_decoder(), but when using lzma_alone_decoder() directly, such files will now be accepted. Hopefully this is an OK compromise. This doesn't affect xz because xz still has its own file format detection code. This does affect lzmadec though. So after this commit lzmadec will accept files that xz or xz-emulating-lzma doesn't. NOTE: lzma_alone_decoder() still won't decode all .lzma files because liblzma's LZMA decoder doesn't support lc + lp > 4. Reported here: http://sourceforge.net/projects/lzmautils/forums/forum/708858/topic/7068827 Conflicts: src/liblzma/common/alone_decoder.c src/liblzma/common/alone_decoder.h
2013-04-05Avoid unneeded use of awk in xzless.Lasse Collin1-2/+1
Use "read" instead of "awk" in xzless to get the version number of "less". The need for awk was introduced in the commit db5c1817fabf7cbb9e4087b1576eb26f0747338e. Thanks to Ariel P for the patch.
2012-12-15xzless: Make "less -V" parsing more robustJonathan Nieder1-1/+2
In v4.999.9beta~30 (xzless: Support compressed standard input, 2009-08-09), xzless learned to parse ‘less -V’ output to figure out whether less is new enough to handle $LESSOPEN settings starting with “|-”. That worked well for a while, but the version string from ‘less’ versions 448 (June, 2012) is misparsed, producing a warning: $ xzless /tmp/test.xz; echo $? /usr/bin/xzless: line 49: test: 456 (GNU regular expressions): \ integer expression expected 0 More precisely, modern ‘less’ lists the regexp implementation along with its version number, and xzless passes the entire version number with attached parenthetical phrase as a number to "test $a -gt $b", producing the above confusing message. $ less-444 -V | head -1 less 444 $ less -V | head -1 less 456 (no regular expressions) So relax the pattern matched --- instead of expecting "less <number>", look for a line of the form "less <number>[ (extra parenthetical)]". While at it, improve the behavior when no matching line is found --- instead of producing a cryptic message, we can fall back on a LESSPIPE setting that is supported by all versions of ‘less’. The implementation uses "awk" for simplicity. Hopefully that’s portable enough. Reported-by: Jörg-Volker Peetz <jvpeetz@web.de> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

2012-05-29liblzma: Fix possibility of incorrect LZMA_BUF_ERROR.Lasse Collin1-1/+1
lzma_code() could incorrectly return LZMA_BUF_ERROR if all of the following was true: - The caller knows how many bytes of output to expect and only provides that much output space. - When the last output bytes are decoded, the caller-provided input buffer ends right before the LZMA2 end of payload marker. So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return LZMA_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. Another situation where the bug can be triggered happens if the uncompressed size is zero bytes and no output space is provided. In this case the decompression can fail even if the whole input file is given to lzma_code(). A similar bug was fixed in XZ Embedded on 2011-09-19.
2012-05-29xz: Don't show a huge number in -vv when memory limit is disabled.Lasse Collin1-1/+11
2012-05-29xz: Document the "summary" lines of --robot -lvv.Lasse Collin1-0/+19
This documents only the columns that are in v5.0. The new columns added in the master branch aren't necessarily stable yet.
2012-05-29xz: Fix output of verbose --robot --list modes.Lasse Collin1-1/+1
It printed the filename in "filename (x/y)" format which it obviously shouldn't do in robot mode.
2012-05-24liblzma: Remove outdated comments.Lasse Collin2-5/+1
2012-05-24Fix exit status of xzgrep when grepping binary files.Lasse Collin1-1/+2
When grepping binary files, grep may exit before it has read all the input. In this case, gzip -q returns 2 (eating SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status (e.g. 141). This causes wrong exit status when grepping xz- or bzip2-compressed binary files. The fix checks for the special exit status that indicates SIGPIPE. It uses kill -l which should be supported everywhere since it is in both SUSv2 (1997) and POSIX.1-2008. Thanks to James Buren for the bug report.

2011-09-05Fix exit status of "xzdiff foo.xz bar.xz".Lasse Collin1-0/+2
xzdiff was clobbering the exit status from diff in a case statement used to analyze the exit statuses from "xz" when its operands were two compressed files. Save and restore diff's exit status to fix this. The bug is inherited from zdiff in GNU gzip and was fixed there on 2009-10-09. Thanks to Jonathan Nieder for the patch and to Peter Pallinger for reporting the bug.

2011-05-28xz: Fix error handling in xz -lvv.Lasse Collin1-15/+6
It could do an invalid free() and read past the end of the uninitialized filters array.

It didn't mention the return value that is used if an error occurs.
2011-04-11liblzma: Don't create an empty Block in lzma_stream_buffer_encode().Lasse Collin1-7/+13
Empty Block was created if the input buffer was empty. Empty Block wastes a few bytes of space, but more importantly it triggers a bug in XZ Utils 5.0.1 and older when trying to decompress such a file. 5.0.1 and older consider such files to be corrupt. I thought that no encoder creates empty Blocks when releasing 5.0.2 but I was wrong.
2011-04-11liblzma: Fix API docs to mention LZMA_UNSUPPORTED_CHECK.Lasse Collin2-0/+4
This return value was missing from the API comments of four functions.
2011-04-11liblzma: Validate encoder arguments better.Lasse Collin3-6/+20
The biggest problem was that the integrity check type wasn't validated, and e.g. lzma_easy_buffer_encode() would create a corrupt .xz Stream if given an unsupported Check ID. Luckily applications don't usually try to use an unsupport Check ID, so this bug is unlikely to cause many real-world problems.
2011-04-09liblzma: Add missing #ifdefs to filter_common.c.Lasse Collin1-3/+3
Passing --disable-decoders to configure broke a few encoders due to missing #ifdefs in filter_common.c. Thanks to Jason Gorski for the patch.
2011-04-05liblzma: Fix a memory leak in stream_encoder.c.Lasse Collin1-1/+1
It leaks old filter options structures (hundred bytes or so) every time the lzma_stream is reinitialized. With the xz tool, this happens when compressing multiple files.
2011-04-01Bumped version and liblzma soname to 5.0.2.larhzu/v5.0.2Lasse Collin2-2/+2
2011-03-31liblzma: Fix decoding of LZMA2 streams having no uncompressed data.Lasse Collin1-4/+4
The decoder considered empty LZMA2 streams to be corrupt. This shouldn't matter much with .xz files, because no encoder creates empty LZMA2 streams in .xz. This bug is more likely to cause problems in applications that use raw LZMA2 streams.
2011-03-24Scripts: Better fix for xzgrep.Lasse Collin1-2/+6
Now it uses "grep -q". Thanks to Gregory Margo.
2011-03-24Scripts: Fix xzgrep -l.Lasse Collin1-2/+2
It didn't work at all. It tried to use the -q option for grep, but it appended it after "--". This works around it by redirecting to /dev/null. The downside is that this can be slower with big files compared to proper use of "grep -q". Thanks to Gregory Margo.
2011-02-04xz: Clean up suffix.c.Lasse Collin1-24/+20
struct suffix_pair isn't needed in compresed_name() so get rid of it there.
2011-02-04xz: Check if the file already has custom suffix when compressing.Lasse Collin1-0/+9
Now "xz -S .test foo.test" refuses to compress the file because it already has the suffix .test. The man page had it documented this way already.

2010-10-23liblzma: Make lzma_code() check the reserved members in lzma_stream.Lasse Collin1-0/+14
If any of the reserved members in lzma_stream are non-zero or non-NULL, LZMA_OPTIONS_ERROR is returned. It is possible that a new feature in the future is indicated by just setting a reserved member to some other value, so the old liblzma version need to catch it as an unsupported feature.
2010-10-23Windows: Use MinGW's stdio functions.Lasse Collin1-0/+5
The non-standard ones from msvcrt.dll appear to work most of the time with XZ Utils, but there are some corner cases where things may go very wrong. So it's good to use the better replacements provided by MinGW(-w64) runtime.

Those are the same thing, and the former makes it a bit easier to build the code with other build systems, because one doesn't need to update the version number into custom config.h. This change affects only lzmainfo. Other tools were already using LZMA_VERSION_STRING.
2010-10-08Build: Add options to disable individual command line tools.Lasse Collin4-40/+55
2010-10-05Build: Remove the static/dynamic tricks.Lasse Collin3-9/+3
Most distros want xz linked against shared liblzma, so it doesn't help much to require --enable-dynamic for that. Those who want to avoid PIC on x86-32 to get better performance, can still do it e.g. by using --disable-shared to compile xz and then another pass to compile shared liblzma. Part of these static/dynamic tricks were needed for Windows in the past. Nowadays we rely on GCC and binutils to do the right thing with auto-import. If the Autotooled build system needs to support some other toolchain on Windows in the future, this may need some rethinking.

2010-09-10xz: Multiple fixes.Lasse Collin10-187/+393
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.

I had somehow thought that N_() is usually used as shorthand for ngettext(). This also fixes a missing \n from a call to ngettext().
2010-09-06xz: Improve a comment.Lasse Collin1-3/+4
2010-09-05xz: Update the comment about NetBSD in file_io.c.Lasse Collin1-4/+4
Thanks to Joerg Sonnenberger.
2010-09-05xz: Use an array instead of pointer for stdin_filename.Lasse Collin2-2/+2
Thanks Joerg Sonnenberger.
2010-09-05xz: Hopefully ease translating the messages in list.c.Lasse Collin1-10/+23
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
2010-09-03xz: 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
2010-08-07Disable 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
2010-07-28Language fixes for man pages.Lasse Collin2-5/+5
Thanks to A. Costa and Jonathan Nieder.

Thanks to Denis Excoffier for the bug report.
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
I want to get a bug report if something else than DJGPP lacks SA_RESTART.
2010-06-01xz man page updates.Lasse Collin1-19/+366
- Concatenating .xz files and padding - List mode - Robot mode - A few examples (but many more are needed)
2010-06-01Major update to xz --list.Lasse Collin1-181/+471
2010-06-01Rename message_filters_get() to message_filters_to_str().Lasse Collin2-3/+3

2010-05-27Fix lzma_block_compressed_size().Lasse Collin1-3/+3
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 Collin1-9/+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 Collin14-29/+29
This should avoid some minor portability issues.
2010-05-26Better #error message.Lasse Collin1-2/+2
2010-05-26Remove the Subblock filter code for now.Lasse Collin18-2102/+1
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.
2010-05-10Updates to tuklib_physmem and tuklib_cpucores.Lasse Collin2-3/+44
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 Collin1-48/+38
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.
2010-03-07Fix 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.
2010-03-07Increase 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.
2010-03-06Fix 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.

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.

2010-02-01Fix compression of symlinks with --force.Lasse Collin1-1/+13
xz --force accepted symlinks, but didn't remove them after successful compression. Instead, an error message was displayed.
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.

This should have been already in 0bc9eab243dee3be764b3530433a7fcdc3f7c6a1.

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.
2010-01-24Some improvements to printing sizes in xz.Lasse Collin5-90/+166

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 Collin2-0/+25
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 Collin8-724/+1466
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.

2009-12-09Always 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.

2009-11-25Fix bugs in lzma_index_read() and lzma_index_cat().Lasse Collin1-11/+19
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.
