Pedro Alves 9ccabccd15 Python unwinder sniffer: PyExc_KeyboardInterrupt -> Quit ... If you happen to press Ctrl-C while GDB is running the Python unwinder machinery, the Ctrl-C is swallowed by the Python unwinder machinery. For example, with: break foo commands > c > end and while (1) foo (); and then let the inferior hit "foo" repeatedly, sometimes Ctrl-C results in: ~~~ 23 usleep (100); Breakpoint 2, foo () at gdb.base/bp-cmds-continue-ctrl-c.c:23 23 usleep (100); ^C Breakpoint 2, Python Exception <class 'KeyboardInterrupt'> <class 'KeyboardInterrupt'>: foo () at gdb.base/bp-cmds-continue-ctrl-c.c:23 23 usleep (100); Breakpoint 2, foo () at gdb.base/bp-cmds-continue-ctrl-c.c:23 23 usleep (100); Breakpoint 2, foo () at gdb.base/bp-cmds-continue-ctrl-c.c:23 23 usleep (100); ~~~ Notice the Python exception above. The interesting thing here is that GDB continues as if nothing happened, doesn't really stop and give back control to the user. Instead, the Ctrl-C aborted the Python unwinder sniffer and GDB moved on to just use another unwinder. Fix this by translating a PyExc_KeyboardInterrupt back into a Quit exception once back in GDB. This was exposed by the new gdb.base/bp-cmds-continue-ctrl-c.exp testcase added later in the series. gdb/ChangeLog: 2017-11-16 Pedro Alves <palves@redhat.com> * python/py-unwind.c (pyuw_sniffer): Translate PyExc_KeyboardInterrupt to a GDB Quit exception.		2017-11-16 18:44:44 +00:00
