New features and improvements: * Added support for the -Xclang compiler option. * Improved handling of exit code of internally executed processes. * Zero length object files in the cache are now rejected as invalid. * Bail out on option -gsplit-dwarf (since it produces multiple output files). * Compiler option -fdebug-prefix-map is now ignored (not part of the hash). (The -fdebug-prefix-map option may be used in combination with CCACHE_BASEDIR to reuse results across different directories.) * Added note in documentation that --ccache-skip currently does not mean “don’t hash the following option”. * To enable support for precompiled headers (PCH), CCACHE_SLOPPINESS now also needs to include the new pch_defines sloppiness. This is because ccache can’t detect changes in the source code when only defined macros have been changed. * Stale files in the internal temporary directory (<ccache_dir>/tmp) are now cleaned up if they are older than one hour. Bug fixes: * Fixed path canonicalization in make_relative_path() when path doesn’t exist. * Fixed bug in common_dir_prefix_length(). This corrects the CCACHE_BASEDIR behavior. * ccache no longer tries to create the cache directory when CCACHE_DISABLE is set. * Fixed bug when reading manifests with a very large number of file info entries. * Fixed problem with logging of current working directory. |
