2020-12-05Scripts: Add zstd support to xzgrep.Adam Borowski2-3/+7
Thanks to Adam Borowski.
2020-11-17CMake: Fix compatibility with CMake 3.13.Lasse Collin3-5/+5
The syntax "if(DEFINED CACHE{FOO})" requires CMake 3.14. In some other places the code treats the cache variables like normal variables already (${FOO} or if(FOO) is used, not ${CACHE{FOO}). Thanks to ygrek for reporting the bug on IRC.

2020-11-01xz: Avoid unneeded \f escapes on the man page.Lasse Collin1-9/+22
I don't want to use \c in macro arguments but groff_man(7) suggests that \f has better portability. \f would be needed for the .TP strings for portability reasons anyway. Thanks to Bjarni Ingi Gislason.
2020-11-01xz: Use non-breaking spaces when intentionally using more than one space.Lasse Collin1-1/+1
This silences some style checker warnings. Seems that spaces in the beginning of a line don't need this treatment. Thanks to Bjarni Ingi Gislason.
2020-11-01xz: Protect the ellipsis (...) on the man page with \&.Lasse Collin1-2/+2
This does it only when ... appears outside macro calls. Thanks to Bjarni Ingi Gislason.
2020-11-01xz: Avoid the abbreviation "e.g." on the man page.Lasse Collin1-33/+33
A few are simply omitted, most are converted to "for example" and surrounded with commas. Sounds like that this is better style, for example, man-pages(7) recommends avoiding such abbreviations except in parenthesis. Thanks to Bjarni Ingi Gislason.
2020-07-12xz man page: Change \- (minus) to \(en (en-dash) for a numeric range.Lasse Collin1-8/+8
Docs of ancient troff/nroff mention \(em (em-dash) but not \(en and \- was used for both minus and en-dash. I don't know how portable \(en is nowadays but it can be changed back if someone complains. At least GNU groff and OpenBSD's mandoc support it. Thanks to Bjarni Ingi Gislason for the patch.
2020-07-12Windows: Fix building of resource files when config.h isn't used.Lasse Collin1-1/+3
Now CMake + Visual Studio works for building liblzma.dll. Thanks to Markus Rickert.

2020-02-25Update THANKS.Lasse Collin1-0/+1
2020-02-25Build: Fix bugs in the CMake files.Lasse Collin7-78/+85
Seems that the phrase "add more quotes" from sh/bash scripting applies to CMake as well. E.g. passing an unquoted list ${FOO} to a function that expects one argument results in only the first element of the list being passed as an argument and the rest get ignored. Adding quotes helps ("${FOO}"). list(INSERT ...) is weird. Inserting an empty string to an empty variable results in empty list, but inserting it to a non-empty variable does insert an empty element to the list. Since INSERT requires at least one element, "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt. It might result in an empty element in the list. It seems to not matter as empty elements consistently get ignored in that variable. In fact, calling cmake_check_push_state() and cmake_check_pop_state() will strip the empty elements from CMAKE_REQUIRED_LIBRARIES! In addition to quoting fixes, this fixes checks for the cache variables in tuklib_cpucores.cmake and tuklib_physmem.cmake. Thanks to Martin Matuška for testing and reporting the problems. These fixes aren't tested yet but hopefully they soon will be.
2020-02-25Build: Add very limited experimental CMake support.Lasse Collin7-0/+1151
This does *NOT* replace the Autotools-based build system in the foreseeable future. See the comment in the beginning of CMakeLists.txt. So far this has been tested only on GNU/Linux but I commit it anyway to make it easier for others to test. Since I haven't played much with CMake before, it's likely that there are things that have been done in a silly or wrong way and need to be fixed.
2020-02-24Update m4/.gitignore.Lasse Collin1-0/+1
2020-02-24tuklib: Omit an unneeded <sys/types.h> from a tests.Lasse Collin2-2/+0
tuklib_cpucores.c and tuklib_physmem.c don't include <sys/types.h> even via other files in this package, so clearly that header isn't needed in the tests either (no one has reported build problems due to a missing header in a .c file).
2020-02-24liblzma: Remove unneeded <sys/types.h> from fastpos_tablegen.c.Lasse Collin1-1/+0
This file only generates fastpos_table.c. It isn't built as a part of liblzma.
2020-02-22Use defined(__GNUC__) before __GNUC__ in preprocessor lines.Lasse Collin2-3/+5
This should silence the equivalent of -Wundef in compilers that don't define __GNUC__.
2020-02-21liblzma: Add more uses of lzma_memcmplen() to the normal mode of LZMA.Lasse Collin1-6/+10
This gives a tiny encoder speed improvement. This could have been done in 2014 after the commit 544aaa3d13554e8640f9caf7db717a96360ec0f6 but it was forgotten.
2020-02-21Build: Add visibility.m4 from gnulib.Lasse Collin2-1/+77
Appears that this file used to get included as a side effect of gettext. After the change to gettext version requirements this file no longer got copied to the package and so the build was broken.

2020-02-20tuklib_exit: Add missing header.Lasse Collin1-0/+1
strerror() needs <string.h> which happened to be included via tuklib_common.h -> tuklib_config.h -> sysdefs.h if HAVE_CONFIG_H was defined. This wasn't tested without config.h before so it had worked fine.
2020-02-18Revert the previous commit and add a comment.Lasse Collin1-7/+10
The previous commit broke crc32_tablegen.c. If the whole package is built without config.h (with defines set on the compiler command line) this should still work fine as long as these headers conform to C99 well enough.
2020-02-17Do not check for HAVE_CONFIG_H in tuklib_config.h.Lasse Collin1-8/+7
In XZ Utils sysdefs.h takes care of it and the required headers.
2020-02-16sysdefs.h: Omit the conditionals around string.h and limits.h.Lasse Collin1-6/+2
string.h is used unconditionally elsewhere in the project and configure has always stopped if limits.h is missing, so these headers must have been always available even on the weirdest systems.
2020-02-15Build: Bump Autoconf and Libtool version requirements.Lasse Collin1-2/+2
There is no specific reason for this other than blocking the most ancient versions. These are still old: Autoconf 2.69 (2012) Automake 1.12 (2012) gettext 0.19.6 (2015) Libtool 2.4 (2010)
2020-02-15Build: Use AM_GNU_GETTEXT_REQUIRE_VERSION and require 0.19.6.Lasse Collin1-1/+5
This bumps the version requirement from 0.19 (from 2014) to 0.19.6 (2015). Using only the old AM_GNU_GETTEXT_VERSION results in old gettext infrastructure being placed in the package. By using both macros we get the latest gettext files while the other programs in the Autotools family can still see the old macro.
2020-02-14Translations: Add German translation of the man pages.Lasse Collin2-1/+5533
Thanks to Mario Blättermann.
2020-02-07Build: Add support for translated man pages using po4a.Lasse Collin8-45/+197
The dependency on po4a is optional. It's never required to install the translated man pages when xz is built from a release tarball. If po4a is missing when building from xz.git, the translated man pages won't be generated but otherwise the build will work normally. The translations are only updated automatically by autogen.sh and by "make mydist". This makes it easy to keep po4a as an optional dependency and ensures that I won't forget to put updated translations to a release tarball. The translated man pages aren't installed if --disable-nls is used. The installation of translated man pages abuses Automake internals by calling "install-man" with redefined dist_man_MANS and man_MANS. This makes the hairy script code slightly less hairy. If it breaks some day, this code needs to be fixed; don't blame Automake developers. Also, this adds more quotes to the existing shell script code in the Makefile.am "-hook"s.

2020-02-05Build: Workaround a POSIX shell detection problem on Solaris.Lasse Collin1-0/+10
I don't know if the problem is in gnulib's gl_POSIX_SHELL macro or if xzgrep does something that isn't in POSIX. The workaround adds a special case for Solaris: if /usr/xpg4/bin/sh exists and gl_cv_posix_shell wasn't overriden on the configure command line, use that shell for xzgrep and other scripts. That shell is known to work and exists on most Solaris systems.
2020-02-03Build: Update m4/ax_pthread.m4 from Autoconf Archive.Lasse Collin1-119/+279
2020-02-01xz: Limit --memlimit-compress to at most 4020 MiB for 32-bit xz.Lasse Collin2-2/+51
See the code comment for reasoning. It's far from perfect but hopefully good enough for certain cases while hopefully doing nothing bad in other situations. At presets -5 ... -9, 4020 MiB vs. 4096 MiB makes no difference on how xz scales down the number of threads. The limit has to be a few MiB below 4096 MiB because otherwise things like "xz --lzma2=dict=500MiB" won't scale down the dict size enough and xz cannot allocate enough memory. With "ulimit -v $((4096 * 1024))" on x86-64, the limit in xz had to be no more than 4085 MiB. Some safety margin is good though. This is hack but it should be useful when running 32-bit xz on a 64-bit kernel that gives full 4 GiB address space to xz. Hopefully this is enough to solve this: https://bugzilla.redhat.com/show_bug.cgi?id=1196786 FreeBSD has a patch that limits the result in tuklib_physmem() to SIZE_MAX on 32-bit systems. While I think it's not the way to do it, the results on --memlimit-compress have been good. This commit should achieve practically identical results for compression while leaving decompression and tuklib_physmem() and thus lzma_physmem() unaffected.
2020-01-26xz: Set the --flush-timeout deadline when the first input byte arrives.Lasse Collin3-7/+6
xz --flush-timeout=2000, old version: 1. xz is started. The next flush will happen after two seconds. 2. No input for one second. 3. A burst of a few kilobytes of input. 4. No input for one second. 5. Two seconds have passed and flushing starts. The first second counted towards the flush-timeout even though there was no pending data. This can cause flushing to occur more often than needed. xz --flush-timeout=2000, after this commit: 1. xz is started. 2. No input for one second. 3. A burst of a few kilobytes of input. The next flush will happen after two seconds counted from the time when the first bytes of the burst were read. 4. No input for one second. 5. No input for another second. 6. Two seconds have passed and flushing starts.
2020-01-26xz: Move flush_needed from mytime.h to file_pair struct in file_io.h.Lasse Collin5-9/+7
2020-01-26xz: coder.c: Make writing output a separate function.Lasse Collin1-13/+17
The same code sequence repeats so it's nicer as a separate function. Note that in one case there was no test for opt_mode != MODE_TEST, but that was only because that condition would always be true, so this commit doesn't change the behavior there.
2020-01-26xz: Fix semi-busy-waiting in xz --flush-timeout.Lasse Collin3-4/+19
When input blocked, xz --flush-timeout=1 would wake up every millisecond and initiate flushing which would have nothing to flush and thus would just waste CPU time. The fix disables the timeout when no input has been seen since the previous flush.

2019-12-31Rename read32ne to aligned_read32ne, and similarly for the others.Lasse Collin3-32/+32
Using the aligned methods requires more care to ensure that the address really is aligned, so it's nicer if the aligned methods are prefixed. The next commit will remove the unaligned_ prefix from the unaligned methods which in liblzma are used in more places than the aligned ones.
2019-12-31Revise tuklib_integer.h and .m4.Lasse Collin2-218/+316
Add a configure option --enable-unsafe-type-punning to get the old non-conforming memory access methods. It can be useful with old compilers or in some other less typical situations but shouldn't normally be used. Omit the packed struct trick for unaligned access. While it's best in some cases, this is simpler. If the memcpy trick doesn't work, one can request unsafe type punning from configure. Because CRC32/CRC64 code needs fast aligned reads, if no very safe way to do it is found, type punning is used as a fallback. This sucks but since it currently works in practice, it seems to be the least bad option. It's never needed with GCC >= 4.7 or Clang >= 3.6 since these support __builtin_assume_aligned and thus fast aligned access can be done with the memcpy trick. Other things: - Support GCC/Clang __builtin_bswapXX - Cleaner bswap fallback macros - Minor cleanups

2019-09-24Scripts: Put /usr/xpg4/bin to the beginning of PATH on Solaris.Lasse Collin6-8/+65
This adds a configure option --enable-path-for-scripts=PREFIX which defaults to empty except on Solaris it is /usr/xpg4/bin to make POSIX grep and others available. The Solaris case had been documented in INSTALL with a manual fix but it's better to do this automatically since it is needed on most Solaris systems anyway. Thanks to Daniel Richard G.

2019-06-24Add LZMA_RET_INTERNAL1..8 to lzma_ret and use one for LZMA_TIMED_OUT.Lasse Collin4-7/+25
LZMA_TIMED_OUT is *internally* used as a value for lzma_ret enumeration. Previously it was #defined to 32 and cast to lzma_ret. That way it wasn't visible in the public API, but this was hackish. Now the public API has eight LZMA_RET_INTERNALx members and LZMA_TIMED_OUT is #defined to LZMA_RET_INTERNAL1. This way the code is cleaner overall although the public API has a few extra mysterious enum members.

2019-06-01tuklib_integer: Improve unaligned memory access.Lasse Collin1-12/+168
Now memcpy() or GNU C packed structs for unaligned access instead of type punning. See the comment in this commit for details. Avoiding type punning with unaligned access is needed to silence gcc -fsanitize=undefined. New functions: unaliged_readXXne and unaligned_writeXXne where XX is 16, 32, or 64.
2019-05-13liblzma: Avoid memcpy(NULL, foo, 0) because it is undefined behavior.Lasse Collin3-5/+23
I should have always known this but I didn't. Here is an example as a reminder to myself: int mycopy(void *dest, void *src, size_t n) { memcpy(dest, src, n); return dest == NULL; } In the example, a compiler may assume that dest != NULL because passing NULL to memcpy() would be undefined behavior. Testing with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1. With -O2 the return value is 0 because the compiler infers that dest cannot be NULL because it was already used with memcpy() and thus the test for NULL gets optimized out. In liblzma, if a null-pointer was passed to memcpy(), there were no checks for NULL *after* the memcpy() call, so I cautiously suspect that it shouldn't have caused bad behavior in practice, but it's hard to be sure, and the problematic cases had to be fixed anyway. Thanks to Jeffrey Walton.

2019-01-13Windows/VS2017: Omit WindowsTargetPlatformVersion from project files.Lasse Collin3-2/+4
I understood that if a WTPV is specified, it's often wrong because different VS installations have different SDK version installed. Omitting the WTPV tag makes VS2017 default to Windows SDK 8.1 which often is also missing, so in any case people may need to specify the WTPV before building. But some day in the future a missing WTPV tag will start to default to the latest installed SDK which sounds reasonable: https://developercommunity.visualstudio.com/content/problem/140294/windowstargetplatformversion-makes-it-impossible-t.html Thanks to "dom".

2018-12-20xz: Fix a crash in progress indicator when in passthru mode.Lasse Collin3-7/+25
"xz -dcfv not_an_xz_file" crashed (all four options are required to trigger it). It caused xz to call lzma_get_progress(&strm, ...) when no coder was initialized in strm. In this situation strm.internal is NULL which leads to a crash in lzma_get_progress(). The bug was introduced when xz started using lzma_get_progress() to get progress info for multi-threaded compression, so the bug is present in versions 5.1.3alpha and higher. Thanks to Filip Palian <Filip.Palian@pjwstk.edu.pl> for the bug report.

FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma is being built for fuzz testing. Most fuzzed inputs would normally get rejected because of incorrect CRC32 and the actual header decoding code wouldn't get fuzzed. Disabling CRC32 checks avoids this problem. The fuzzer program must still use LZMA_IGNORE_CHECK flag to disable verification of integrity checks of uncompressed data.

2017-03-30liblzma: Fix lzma_memlimit_set(strm, 0).Lasse Collin3-3/+13
The 0 got treated specially in a buggy way and as a result the function did nothing. The API doc said that 0 was supposed to return LZMA_PROG_ERROR but it didn't. Now 0 is treated as if 1 had been specified. This is done because 0 is already used to indicate an error from lzma_memlimit_get() and lzma_memusage(). In addition, lzma_memlimit_set() no longer checks that the new limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive for the Index decoder and was actually needed only by the auto decoder. Auto decoder has now been modified to check for LZMA_MEMUSAGE_BASE.
2017-03-30liblzma: Similar memlimit fix for stream_, alone_, and auto_decoder.Lasse Collin4-16/+20
2017-03-30liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().Lasse Collin2-9/+13
It returned LZMA_PROG_ERROR, which was done to avoid zero as the limit (because it's a special value elsewhere), but using LZMA_PROG_ERROR is simply inconvenient and can cause bugs. The fix/workaround is to treat 0 as if it were 1 byte. It's effectively the same thing. The only weird consequence is that then lzma_memlimit_get() will return 1 even when 0 was specified as the limit. This fixes a very rare corner case in xz --list where a specific memory usage limit and a multi-stream file could print the error message "Internal error (bug)" instead of saying that the memory usage limit is too low.

2016-10-24tuklib_cpucores: Add support for sched_getaffinity().Lasse Collin2-1/+38
It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity() gives the number of cores available to the process instead of the total number of cores online. As a side effect, this commit fixes a bug on GNU/kFreeBSD where configure would detect the FreeBSD-specific cpuset_getaffinity() but it wouldn't actually work because on GNU/kFreeBSD it requires using -lfreebsd-glue when linking. Now the glibc-specific function will be used instead. Thanks to Sebastian Andrzej Siewior for the original patch and testing.

2016-03-13liblzma: Disable external SHA-256 by default.Lasse Collin3-49/+79
This is the sane thing to do. The conflict with OpenSSL on some OSes and especially that the OS-provided versions can be significantly slower makes it clear that it was a mistake to have the external SHA-256 support enabled by default. Those who want it can now pass --enable-external-sha256 to configure. INSTALL was updated with notes about OSes where this can be a bad idea. The SHA-256 detection code in configure.ac had some bugs that could lead to a build failure in some situations. These were fixed, although it doesn't matter that much now that the external SHA-256 is disabled by default. MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init in libc instead of libutil. Support for the libutil version was removed.
2016-03-10Update THANKS.Lasse Collin1-0/+1
2016-03-10Build: Avoid SHA256_Init on FreeBSD and MINIX 3.Lasse Collin1-6/+21
On FreeBSD 10 and older, SHA256_Init from libmd conflicts with libcrypto from OpenSSL. The OpenSSL version has different sizeof(SHA256_CTX) and it can cause weird problems if wrong SHA256_Init gets used. Looking at the source, MINIX 3 seems to have a similar issue but I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too. NetBSD has SHA256_Init in libc and they had a similar problem, but they already fixed it in 2009. Thanks to Jim Wilcoxson for the bug report that helped in finding the problem.

The patch is quite long but it's mostly about adding new #ifdefs to omit code when encoders or decoders have been disabled. This adds two new #defines to config.h: HAVE_ENCODERS and HAVE_DECODERS.
2015-11-03Build: Build LZMA1/2 presets also when only decoder is wanted.Lasse Collin2-2/+7
People shouldn't rely on the presets when decoding raw streams, but xz uses the presets as the starting point for raw decoder options anyway. lzma_encocder_presets.c was renamed to lzma_presets.c to make it clear it's not used solely by the encoder code.
2015-11-03Build: Fix configure to handle LZMA1 dependency with LZMA2.Lasse Collin1-5/+0

lzma_index_dup() calls index_dup_stream() which, in case of an error, calls index_stream_end() to free memory allocated by index_stream_init(). However, it illogically didn't actually free the memory. To make it logical, the tree handling code was modified a bit in addition to changing index_stream_end(). Thanks to Evan Nemerson for the bug report.

Provide an update of the German translation. * A lot of compound words were previously written with spaces, while German orthography is relatively clear in that the components should not be separated. * When referring to the actual process of (de)compression rather than the concept, replace “(De-)Kompression” with “(De-)Komprimierung”. Previously, both forms were used in this context and are now used in a manner consistent with “Komprimierung” being more likely to refer to a process. * Consistently translate “standard input”/“output” * Use “Zeichen” instead of false friend “Charakter” for “character” * Insert commas around relative clauses (as required in German) * Some other minor corrections * Capitalize “ß” as “ẞ” * Consistently start option descriptions in --help with capital letters Acked-By: Andre Noll <maan@tuebingen.mpg.de> * Update after msgmerge
