            Bug ID: 31368
           Summary: make debuginfod downloads interruptible
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

Like bug #29582 (gdb), we need systemtap to react to ^C's when debuginfod
downloads are in progress.  For example, try something very slow like:


 % stap -L 'module("ac*").function("*")'

and hit ^C.  It may or may not interrupt that download, but then proceeds
to the next one. By hitting ^C enough, systemtap's "Too many interrupts
received, exiting" logic eventually fires, aborting the program.  It would
be better if that first ^C were immediately interpreted as an interrupt
in whatever part of stap/elfutils is busy with the downloads.  This may or
may not require dealing with debuginfod_client level notifier callbacks.
