            Bug ID: 31434
           Summary: [gdb/dap, testsuite] Test race of cancellation with
                    end of request
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: dap
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

The test-case pause.exp is the only dap test-case that tests cancellation.

There are three requests cancelled:
- a continue
- a loop in gdb
- a loop in python

For all three, I think the race between cancellation and start of request is
excercised.

For the first one, the cancellation is caught by _on_stop, so the end of
request is only reached via normal return.

For the last two, since both of them hang, the end of request is only reach=
ed
through cancellation.

Consequently, the race between cancellation and end of request is currently
untested.
