Right now, gdb has a commit script on sourcware that looks for bugzilla references like "PR blah/NNNN"; and then it records the commit information in bugzilla (but see bug #30029). It would be nice for gdb to extend this treatment to patches. More than once, we've lost a patch and then, much later, had to dig it out of the mail archives. If the patch had been recorded in bugzilla when sent, it would have been much more convenient. The idea here is to use the same logic from the commit script to scan email to gdb-patches; then put a link to public inbox (presumably using the message-id) into the correct bug in bugzilla. Public inbox is preferred here because I think it does a better job at associating a message-id to a thread than the other mail archive.
