            Bug ID: 27983
           Summary: debuginfod client should eliminate duplicate outgoing
                    server urls
           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: ---

Gazing at server logs, one sees a minority of clients who appear to have
duplicate query traffic coming in: the same URL, milliseconds apart.  Chanc=
es
are the user accidentally doubled her $DEBUGINFOD_URLS somehow, and the cli=
ent
library is dutifully asking the servers TWICE.  Bug #27863 reduces the pain=
 on
the servers' CPU, but dupe network traffic is still being paid.  We should
reject sending outright duplicate concurrent traffic.
