When a source string is removed from the VCS, we mark corresponding Entity object as obsolete in the DB.

When a source file is removed from the VCS, we delete the corresponding Resource object from the DB.

That's inconsistent.

We should unify the behaviour by marking corresponding Resource objects as obsolete when source files are removed. One of the consequences will be more accurate contributor stats.

When the Resource is made obsolete, we should set the value of the date_obsoleted field (see bug #1473749).
