If one is watching new_objfile events in python, it helps to know when the list of objfiles is cleared. This patch adds a new clear_objfiles event to support this. This patch is all just cut-n-paste-n-tweak derived from the new_objfiles event. gdb/ChangeLog: * NEWS: Mention new event gdb.clear_objfiles. * python/py-event.h (emit_clear_objfiles_event): Clear * python/py-events.h (events_object): New member clear_objfiles. * python/py-evts.c (gdbpy_initialize_py_events): Add clear_objfiles event. * python/py-inferior.c (python_new_objfile): If objfile is NULL, emit clear_objfiles event. * python/py-newobjfileevent.c (create_clear_objfiles_event_object): New function. (emit_clear_objfiles_event): New function. (clear_objfiles): New event. * python/python-internal.h (gdbpy_initialize_clear_objfiles_event): Declare. * python/python.c (_initialize_python): Call gdbpy_initialize_clear_objfiles_event. gdb/doc/ChangeLog: * python.texi (Events In Python): Document clear_objfiles event. gdb/testsuite/ChangeLog: * gdb.python/py-events.exp: Update expected output for clear_objfiles event. * gdb.python/py-events.py: Add clear_objfiles event.

/* This macro creates the following functions:

gdbpy_initialize_{NAME}_event

Used to add the newly created event type to the gdb module.

and the python type data structure for the event:

|
|
|
struct PyTypeObject {NAME}_event_object_type
|
|
|
|
NAME is the name of the event.
|
|
PY_PATH is a string representing the module and python name of

|
the event.
|
|
PY_NAME a string representing what the event should be called in
|
|
python.
|
|
DOC Python documentation for the new event type
|
|
BASE the base event for this event usually just event_object_type.
|
|
QUAL qualification for the create event usually 'static'
