I'm happy to announce ccache version 3.1, which contains new features and some bug fixes.
Details may be read in the release notes: http://ccache.samba.org/releasenotes.html Source archives are available here: http://samba.org/ftp/ccache/ccache-3.1.tar.bz2 http://samba.org/ftp/ccache/ccache-3.1.tar.gz http://samba.org/ftp/ccache/ccache-3.1.tar.xz The source archives have been signed with my OpenPGP key (BB845E97): http://samba.org/ftp/ccache/ccache-3.1.tar.bz2.asc http://samba.org/ftp/ccache/ccache-3.1.tar.gz.asc http://samba.org/ftp/ccache/ccache-3.1.tar.xz.asc You can run "gpg --verify ccache-3.1.tar.*.asc" to check the source archive integrity after download. Changes since version 3.0.1: New features and improvements: - Added support for hashing the output of a custom command (e.g. "$compiler --version") to identify the compiler instead of stat-ing or hashing the compiler binary. This can improve robustness when the compiler (as seen by ccache) actually isn't the real compiler but another compiler wrapper. - Added support for caching compilations that use precompiled headers. (See the manual for important instructions regarding this.) - Locking of the files containing statistics counters is now done using symlinks instead of POSIX locks. This should make ccache behave a lot better on file systems where POSIX locks are slow or broken (e.g. NFS on some systems). - Manifest files are now updated without the need of taking locks. - Updates of statistics counters are now always done in one of the sub-level statistics files. This reduces lock contention, which especially improves performance on slow NFS mounts. - Reading and writing of statistics counters has been made forward-compatible (unknown counters are retained). - Files are now read without using mmap(). This has two benefits: it's more robust against file changes during reading and it improves performance on poor systems where mmap() doesn't use the disk cache. - Added ".cp" and ".CP" as known C++ suffixes. - Improved logging. - Added "-install_name" as an option known to take an argument. (This improves statistics when using the Darwin linker.) Bug fixes: - Non-fatal error messages are now never printed to stderr but logged instead. - Fixed a bug affecting failing commands when "--ccache-skip" is used. - Made "--ccache-skip" work for all options. - EINTR is now handled correctly. Other: - Work on porting ccache to win32 (native), mostly done by Ramiro Polla. The port is not yet finished, but will hopefully be complete in some subsequent release. - Added a "--nostats" flag to the performance benchmark program. - Made the performance benchmark program more accurate when measuring cache hits. - Added a new test framework for unit tests written in C. - Got rid of "configure-dev"; dev mode is now given by "dev.mk.in" presence. - Improved documentation on how to combine ccache with other compiler wrappers (like "distcc"). - New "LICENSE.txt" file with licensing and copyright details about bundled source code. - New "AUTHORS.txt" file with a list of ccache contributors. - New "HACKING.txt" file with some notes about ccache code conventions. -- Joel _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
