1000723 - Keep track of stdout/stderr in sccache

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Mike Hommey [:glandium]]

Currently, sccache doesn't store anything else than the object files in cache, so when there is a cache hit, we don't get anything that would normally be output without the cache, like warnings.

Allow to store more than one object file in CacheData, and add stderr

Can you add some top-level documentation to CacheData? My understanding from the code is that each cache object is now a zip file that contains three "files", named "obj", "stdout", and "stderr", but it's not so obvious without looking at server.py.

Also some detail about when it is necessary to update CacheData.VERSION and when it's not would be helpful.
