A quick question: man page suggests that it is possible to share ccache across multiple developers by following a set of rules for permissions, umask and setting up of ccache dirs env vars etc. What it doesn't talk about is what happens if two developers are compiling at the same time and there is a cache miss and ccache needs to write the newly created object to the ccache directory.
What happens to two (or more) write calls arriving at the same time? Is there some sort of locking in place to avoid getting garbage in the resultant object file? What about the case where one gets a hit and wants to read while the other gets a miss and wants to overwrite the object with the new object file? And the case, where cache size management needs to throw away an existing object file to replace with another object file? Another developer's run may be reading it while this run is throwing it away. Thanks for your time! -devsk _______________________________________________ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
