This can improve robustness when the compiler (as seen by ccache) actually isn't the real compiler but another compiler wrapper. + - Added support for compilations using 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 (e.g. NFS) where broken POSIX locks are slow or broken. + - Locks are no longer taken when updating manifest files. (A race between two writing processes will only result in one lost entry, which is not a big deal, and it's also very unlikely.) + - 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 is now 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.
