From 6b95f5ad9684530960eb828c76755a7b27a44e43 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Wed, 5 May 2021 15:26:28 +0100 Subject: gdb/python: allow for catchpoint type breakpoints in python This commit adds initial support for catchpoints to the python breakpoint API. This commit adds a BP_CATCHPOINT constant which corresponds to GDB's internal bp_catchpoint. The new constant is documented in the manual. The user can't create breakpoints with type BP_CATCHPOINT after this commit, but breakpoints that already exist, obtained with the `gdb.breakpoints` function, can now have this type. Additionally, when a stop event is reported for hitting a catchpoint, GDB will now report a BreakpointEvent with the attached breakpoint being of type BP_CATCHPOINT - previously GDB would report a generic StopEvent in this situation. gdb/ChangeLog: * NEWS: Mention Python BP_CATCHPOINT feature. * python/py-breakpoint.c (pybp_codes): Add bp_catchpoint support. (bppy_init): Likewise. (gdbpy_breakpoint_created): Likewise. gdb/doc/ChangeLog: * python.texinfo (Breakpoints In Python): Add BP_CATCHPOINT description. gdb/testsuite/ChangeLog: * gdb.python/py-breakpoint.c (do_throw): New function. (main): Call do_throw. * gdb.python/py-breakpoint.exp (test_catchpoints): New proc. --- gdb/python/py-breakpoint.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'gdb/python') diff --git a/gdb/python/py-breakpoint.c b/gdb/python/py-breakpoint.c index a2ce4cd..edff032 100644 --- a/gdb/python/py-breakpoint.c +++ b/gdb/python/py-breakpoint.c @@ -86,6 +86,7 @@ static struct pybp_code pybp_codes[] = { "BP_HARDWARE_WATCHPOINT", bp_hardware_watchpoint}, { "BP_READ_WATCHPOINT", bp_read_watchpoint}, { "BP_ACCESS_WATCHPOINT", bp_access_watchpoint}, + { "BP_CATCHPOINT", bp_catchpoint}, {NULL} /* Sentinel. */ }; @@ -883,6 +884,8 @@ bppy_init (PyObject *self, PyObject *args, PyObject *kwargs) error(_("Cannot understand watchpoint access type.")); break; } + case bp_catchpoint: + error (_("BP_CATCHPOINT not supported")); default: error(_("Do not understand breakpoint type to set.")); } @@ -1038,7 +1041,8 @@ gdbpy_breakpoint_created (struct breakpoint *bp) && bp->type != bp_watchpoint && bp->type != bp_hardware_watchpoint && bp->type != bp_read_watchpoint - && bp->type != bp_access_watchpoint) + && bp->type != bp_access_watchpoint + && bp->type != bp_catchpoint) { pybp_debug_printf ("is not a breakpoint or watchpoint"); return; -- cgit v1.1
