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2013-06-28xz: Remove an outdated NetBSD-specific comment.Lasse Collin1-4/+0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.
2013-06-26Build: Require Automake 1.12 and use serial-tests option.Lasse Collin1-1/+3
It should actually still work with Automake 1.10 if the serial-tests option is removed. Automake 1.13 started using parallel tests by default and the option to get the old behavior isn't supported before 1.12. At least for now, parallel tests don't improve anything in XZ Utils but they hide the progress output from test_compress.sh.
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: 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.

2013-06-26Build: Use -Wvla with GCC if supported.Lasse Collin1-0/+1
Variable-length arrays are mandatory in C99 but optional in C11. The code doesn't currently use any VLAs and it shouldn't in the future either to stay compatible with C11 without requiring any optional C11 features.
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 Collin3-2/+116
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.

2012-05-24Fix 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 Collin3-1/+59
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.

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.

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.

2010-10-21liblzma: Update the comments in the API headers.Lasse Collin14-107/+136
Adding support for LZMA_FINISH for Index encoding and decoding needed tiny additions to the relevant .c files too.
2010-10-19Update INSTALL.generic.Lasse Collin1-18/+81
2010-10-19Clean up a few FIXMEs and TODOs.Lasse Collin6-7/+8
lzma_chunk_size() was commented out because it is currently useless.
2010-10-19Update docs.Lasse Collin4-143/+172
2010-10-12xz: Avoid raise() also on OpenVMS.Lasse Collin1-1/+1
This is similar to DOS/DJGPP that killing the program with a signal will print a backtrace or a similar message.
2010-10-11xz: Avoid SA_RESTART for portability reasons.Lasse Collin3-23/+25
SA_RESTART is not as portable as I had hoped. It's missing at least from OpenVMS, QNX, and DJGPP). Luckily we can do fine without SA_RESTART.
2010-10-10xz: Use "%"PRIu32 instead of "%d" in a format string.Lasse Collin1-1/+1
2010-10-10test_files.sh: Fix the first line.Lasse Collin1-1/+1
For some reason this prevented running the test only on OS/2 and even on that it broke only recently. Thanks to Elbert Pol.
2010-10-10lzmainfo: Use "%"PRIu32 instead of "%u" for uint32_t.Lasse Collin1-1/+1
2010-10-10lzmainfo: Use fileno(stdin) instead of STDIN_FILENO.Lasse Collin1-1/+1
2010-10-09lzmainfo: Use setmode() on DOS-like systems.Lasse Collin1-0/+9
2010-10-09OS/2 and DOS: Be less verbose on signals.Lasse Collin1-0/+7
Calling raise() to kill xz when user has pressed C-c is a bit verbose on OS/2 and DOS/DJGPP. Instead of calling raise(), set only the exit status to 1.
2010-10-09DOS: Update the Makefile, config.h and README.Lasse Collin3-243/+86
This is now simpler and builds only xz.exe.
2010-10-09Windows: Put some license info into README-Windows.txt.Lasse Collin1-4/+4

2010-10-09Windows: Update common_w32res.rc.Lasse Collin1-6/+3
2010-10-09Windows: Make build.bash prefer MinGW-w32 over MinGW.Lasse Collin1-9/+9
This is simply for licensing reasons. The 64-bit version will be built with MinGW-w64 anyway (at least for now), so using it also for 32-bit build allows using the same copyright notice about the MinGW-w64/w32 runtime. Note that using MinGW would require a copyright notice too, because its runtime is not in the public domain either even though MinGW's home page claims that it is public domain. See <http://marc.info/?l=mingw-users&m=126489506214078>.
2010-10-09Windows: Copy COPYING-Windows.txt (if it exists) to the package.Lasse Collin1-2/+12
Also, put README-Windows.txt to the doc directory like the other documentation files.
2010-10-08Windows: Fix build.bash again.Lasse Collin1-3/+4
630a8beda34af0ac153c8051b1bf01230558e422 wasn't good.
2010-10-08Use LZMA_VERSION_STRING instead of PACKAGE_VERSION.Lasse Collin1-1/+1
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.

2010-10-07Windows: Make build.bash work without --enable-dynamic=no.Lasse Collin1-2/+2
2010-10-05Build: Remove the static/dynamic tricks.Lasse Collin6-91/+5
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.
2010-10-05configure.ac: Silence a warning from Autoconf 2.68.Lasse Collin1-1/+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: 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().

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
2010-09-04Adjust 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.
