PR python/19293 notes that when a Python unwinder is disabled, the frame cache is not invalidated. This means that disabling an unwinder doesn't have any immediate effect -- but in my experience it's often the case that I want to enable or disable an unwinder in order to see what happens. This patch adds a new gdb.invalidate_cached_frames function and arranges for the relevant bits of library code to call it. I've only partially documented this function, considering a warning sufficient without going into all the reasons ordinary code should not call it. The name of the new function was taken from a comment in frame.h next to reinit_frame_cache. No new test as I think the updates to the existing test are sufficient to show that the code is working as intended. Built and regtested on x86-64 Fedora 23. 2016-07-12 Tom Tromey <tom@tromey.com> PR python/19293: * python/lib/gdb/command/unwinders.py (do_enable_unwinder): Call gdb.invalidate_cached_frames. * python/lib/gdb/unwinder.py (register_unwinder): Call gdb.invalidate_cached_frames. * python/python.c (gdbpy_invalidate_cached_frames): New function.
