I don't see any major problems, but here are some things to consider: The destination cache shouldn't be used while copying files into it. To get the statistics counters correct, you would also have to merge the counters in $CCACHE_DIR/{*/,}stats. That should be easy since they are just text files containing space-separated integers. (Two of the values are actually the cache size configuration settings, which probably shouldn't be summed.) The manifest files introduced in ccache 3.0 are harder to merge. It's certainly possible to write some code to do it, though. If a manifest file with the same name exists in both of the merged caches, nothing will break if you just select one of them, but some cached results are of course lost (more specifically: direct mode entries for compilations where header files have changed but not the source code file or compiler arguments). > Would there be any issues if different versions of ccache are in use? Not that I can think of. -- Joel _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
