2015-03-30Bump version to 5.3.0alpha and soname to 5.3.99.Lasse Collin1-1/+1
The idea of 99 is that it looks a bit weird in this context. For new features there's no API/ABI stability in devel versions.
2015-02-26Bump version and soname for 5.2.1.larhzu/v5.2.1Lasse Collin1-1/+1
2014-12-21Bump version and soname for 5.2.0.Lasse Collin1-1/+1
I know that soname != app version, but I skip AGE=1 in -version-info to make the soname match the liblzma version anyway. It doesn't hurt anything as long as it doesn't conflict with library versioning rules.
2014-10-29Build: Prepare to support Automake's subdir-objects.Lasse Collin1-2/+2
Due to a bug in Automake, subdir-objects won't be enabled for now. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17354 Thanks to Daniel Richard G. for the original patches.
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.
2014-06-18liblzma: Add lzma_cputhreads().Lasse Collin1-1/+7
2013-09-09Build: 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.
2012-07-05Build: Include validate_map.sh in the distribution.Lasse Collin1-1/+1
It's required by "make mydist". Fix also the location of EXTRA_DIST+= so that those files get distributed also if symbol versioning isn't enabled.
2011-05-28liblzma: Use symbol versioning.Lasse Collin1-0/+6
Symbol versioning is enabled by default on GNU/Linux, other GNU-based systems, and FreeBSD. I'm not sure how stable this is, so it may need backward-incompatible changes before the next release. The idea is that alpha and beta symbols are considered unstable and require recompiling the applications that use those symbols. Once a symbol is stable, it may get extended with new features in ways that don't break compatibility with older ABI & API. The mydist target runs validate_map.sh which should catch some probable problems in liblzma.map. Otherwise I would forget to update the map file for new releases.
2011-04-12Bump the version number to 5.1.1alpha and liblzma soname to 5.0.99.larhzu/v5.1.1alphaLasse Collin1-1/+1
2010-10-23Bump version to 5.0.0 and liblzma version-info to 5:0:0.Lasse Collin1-1/+1
2010-05-26Remove the Subblock filter code for now.Lasse Collin1-5/+0
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.
2009-11-15Add lzma_physmem().Lasse Collin1-2/+3
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.
2009-07-06Use sed instead of $(SED) so that we don't need toLasse Collin1-1/+1
use AC_PROG_SED. We don't do anything fancy with sed, so this should work OK. libtool 2.2 sets SED but 1.5 doesn't, so $(SED) happened to work when using libtool 2.2.
2009-06-30Build system fixesLasse Collin1-17/+62
Don't use libtool convenience libraries to avoid recently discovered long-standing subtle but somewhat severe bugs in libtool (at least 1.5.22 and 2.2.6 are affected). It was found when porting XZ Utils to Windows <http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html> but the problem is significant also e.g. on GNU/Linux. Unless --disable-shared is passed to configure, static library built from a set of convenience libraries will contain PIC objects. That is, while libtool builds non-PIC objects too, only PIC objects will be used from the convenience libraries. On 32-bit x86 (tested on mobile XP2400+), using PIC instead of non-PIC makes the decompressor 10 % slower with the default CFLAGS. So while xz was linked against static liblzma by default, it got the slower PIC objects unless --disable-shared was used. I tend develop and benchmark with --disable-shared due to faster build time, so I hadn't noticed the problem in benchmarks earlier. This commit also adds support for building Windows resources into liblzma and executables.
2009-06-28Add -no-undefined to get shared liblzma on Windows.Lasse Collin1-1/+1
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-10/+3
Some minor documentation cleanups were made at the same time.
2008-12-31Updated src/liblzma/Makefile.am to use liblzma.pc.in, whichLasse Collin1-2/+2
should have been in the previous commit.
2008-09-27Some API changes, bug fixes, cleanups etc.Lasse Collin1-1/+1
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-4/+13
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
