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 ccache 3.0.1 Bug fixes ccache 3.0 General ~~~~~~~ - ccache is now licensed under the GNU General Public License (GPL) version 3 or later. Upgrade notes ~~~~~~~~~~~~~ - The way the hashes are calculated has changed, so you won't get cache hits for compilation results stored by older ccache versions. Because of this, you might as well clear the old cache directory with `ccache --clear` if you want, unless you plan to keep using an older ccache version. New features and improvements ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - ccache now has a ``direct mode'' where it computes a hash of the source code (including all included files) and compiler options without running the preprocessor. By not running the preprocessor, CPU usage is reduced; the speed is somewhere between 1 and 5 times that of ccache running in traditional mode, depending on the circumstances. The speedup will be higher when I/O is fast (e.g., when files are in the disk cache). The direct mode can be disabled by setting +CCACHE_NODIRECT+. - Support has been added for rewriting absolute paths to relative paths when hashing, in order to increase cache hit rate when building the same source code in different directories even when compiling with `-g` and when using absolute include directory paths. This is done by setting the `CCACHE_BASEDIR` environment variable to an absolute path that specifies which paths to rewrite. - Object files are now optionally stored compressed in the cache. The runtime cost is negligible, and more files will fit in the ccache directory and in the disk cache. Set `CCACHE_COMPRESS` to enable object file compression. Note that you can't use compression in combination with the hard link feature. - A `CCACHE_COMPILERCHECK` option has been added. This option tells ccache what compiler-identifying information to hash to ensure that results retrieved from the cache are accurate. Possible values are: none (don't hash anything), mtime (hash the compiler's mtime and size) and content (hash the content of the compiler binary). The default is mtime. - It is now possible to specify extra files whose contents should be included in the hash sum by setting the `CCACHE_EXTRAFILES` option. - Added support for Objective-C and Objective-C\+\+. The statistics counter ``not a C/C++ file'' has been renamed to ``unsupported source language''. - Added support for the `-x` compiler option. - Added support for long command-line options. - A `CACHEDIR.TAG` file is now created in the cache directory. See . - Messages printed to the debug log (specified by `CCACHE_LOGFILE`) have been improved. - You can relax some checks that ccache does in direct mode by setting `CCACHE_SLOPPINESS`. See the manual for more information. - `CCACHE_TEMPDIR` no longer needs to be on the same filesystem as `CCACHE_DIR`. - The default value of `CCACHE_TEMPDIR` has been changed to `$CCACHE_DIR/tmp` to avoid cluttering the top directory. - Temporary files that later will be moved into the cache are now created in the cache directory they will end up in. This makes ccache more friendly to Linux's directory layout. - Improved the test suite and added tests for most of the new functionality. It's now also possible to specify a subset of tests to run. - Standard error output from the compiler is now only stored in the cache if it's non-empty. - If the compiler produces no object file or an empty object file, but gives a zero exit status (could be due to a file system problem, a buggy program specified by `CCACHE_PREFIX`, etc.), ccache copes with it properly. - Added `installcheck` and `distcheck` make targets. - Clarified cache size limit options' and cleanup semantics. - Improved display of cache max size values. - The following options are no longer hashed in the preprocessor mode: `-imacros`, `-imultilib`, `-iprefix`, `-iquote`, `-isysroot`, `-iwithprefix`, `-iwithprefixbefore`, `-nostdinc`, `-nostdinc++` and `-U`.
