            Bug ID: 26810
           Summary: handle duplicate buildid data sources, with some stale
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: debuginfod
          Assignee: unassigned at sourceware dot org
          Reporter: fche at redhat dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

On a large debuginfod test server, we observed that it's possible to have t=
he
same rpm/buildid identified with multiple locations, if the same content is
accessible along several paths.  That part's fine, but if some of the paths
change - get removed - and before the next grooming pass, debuginfod gets
confused.  That's because multiple matches are tried in series (a sqlite sc=
an
loop), but an exception ("file not found") from one iteration can
unintentionally cancel the scan.

So we just need to put a try/catch around the handle_buildid_* function, to
assure that other locations of the same content are attempted, regardless of
exceptions.
