(SUBDIR_PYTHON_OBS): Add py-newobjfileevent.o. Add build rule for this file. * python/py-event.h (emit_new_objfile_event): New prototype. (newobjfile): New Python event emitter. * python/py-evts.c (gdbpy_initialize_py_events): Add new_objfile to Python event registry. * python/py-inferior.c: Include objfiles.h (python_new_objfile): New function. (gdbpy_initialize_inferior): Add python_new_objfile to the new objfile observers. * python/py-newobjfileevent.c: New file. * python-internal.h (gdbpy_initialize_new_objfile_event): New prototype. * python/python.c (_initialize_python): Add gdbpy_initialize_new_objfile_event call. * NEWS: Add item for new Python event "gdb.newobjfile" 2011-10-06 Kevin Pouget Allow Python notification of new object-file loadings. * gdb.texinfo (Events In Python): Document `gdb.NewObjFileEvent' event type. 2011-10-06 Kevin Pouget Allow Python notification of new object-file loadings. * gdb.python/py-events.exp: Test newobjfile event. * gdb.python/py-events.py: Register newobjfile callback. * gdb.python/py-events.c: Add call to shared library * gdb.python/py-events-shlib.c: New file. --- gdb/python/py-inferior.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'gdb/python/py-inferior.c') diff --git a/gdb/python/py-inferior.c b/gdb/python/py-inferior.c index 275caea..afc3eb0 100644 --- a/gdb/python/py-inferior.c +++ b/gdb/python/py-inferior.c @@ -22,6 +22,7 @@ #include "gdbcore.h" #include "gdbthread.h" #include "inferior.h" +#include "objfiles.h" #include "observer.h" #include "python-internal.h" #include "arch-utils.h" @@ -125,6 +126,25 @@ python_inferior_exit (struct inferior *inf) do_cleanups (cleanup); } +/* Callback used to notify Python listeners about new objfiles loaded in the + inferior. */ + +static void +python_new_objfile (struct objfile *objfile) +{ + struct cleanup *cleanup; + + if (objfile == NULL) + return; + + cleanup = ensure_python_env (get_objfile_arch (objfile), current_language); + + if (emit_new_objfile_event (objfile) < 0) + gdbpy_print_stack (); + + do_cleanups (cleanup); +} + /* Return a reference to the Python object of type Inferior representing INFERIOR.
