Subject: [RFA v3 06/13] Allow C-c to work in backtrace in more cases
Date: Fri, 23 Mar 2018 20:55:00 -0000 [thread overview]
Message-ID: <20180323205512.14434-7-tom@tromey.com> (raw)
In-Reply-To: <20180323205512.14434-1-tom@tromey.com>
PR cli/17716 notes that it is difficult to C-c (or "q" at a pagination
prompt) while backtracing using a frame filter. One reason for this
is that many places in py-framefilter.c use RETURN_MASK_ALL in a
try/catch.
This patch changes these spots to use RETURN_MASK_ERROR instead. This
is safe to do because this entire file is exception safe now.

PR cli/17716:
* python/py-framefilter.c (py_print_type, py_print_value)
(enumerate_args, py_print_args, gdbpy_apply_frame_filter): Use
RETURN_MASK_ERROR.
