It seems cleaner to me for functions like create_thread_event_object, which pass object ownership to their callers, to directly return a gdb_ref<>. This way the ownership transfer is part of the API. This patch makes this change. ChangeLog 2017-09-11 Tom Tromey <tom@tromey.com> * python/py-threadevent.c (create_thread_event_object): Return gdbpy_ref. * python/py-stopevent.h (create_stop_event_object) (create_breakpoint_event_object, create_signal_event_object): Update. * python/py-stopevent.c (create_stop_event_object): Return gdbpy_ref. (emit_stop_event): Update. * python/py-signalevent.c (create_signal_event_object): Return gdbpy_ref. * python/py-infevents.c (create_inferior_call_event_object): Update. * python/py-event.h (create_event_object) (create_thread_event_object): Update. * python/py-event.c (create_event_object): Return gdbpy_ref. * python/py-continueevent.c: Return gdbpy_ref. * python/py-bpevent.c (create_breakpoint_event_object): Return gdbpy_ref.
