[bitbake-devel] [PATCH 13/13] lib/bb/parse: properly handle OSError when updating mtime cache

[Paul Eggleton]

If a file no longer exists, drop it from the cache silently instead of
generating a traceback. This was visible in some cases when a recipe was
deleted when bitbake was resident in memory.
