From 5d63b30afa2d1e24a3d1e6fe97507473e0545a02 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 19 Aug 2019 13:41:34 -0600 Subject: Do not expose stub types to Python dwarf2read.c will create stub types for Ada "Taft Amendment" types. These stub types can currently be exposed to Python code, where they show up as TYPE_CODE_VOID types (but that, mysteriously, can sometimes be used in other ways). While it's possible to work with such types by using strip_typedefs, this seemed unpleasant to me. This patch takes another approach instead, which is to try not to expose stub types to Python users. gdb/ChangeLog 2019-09-26 Tom Tromey * python/py-type.c (type_to_type_object): Call check_typedef for stub types. gdb/testsuite/ChangeLog 2019-09-26 Tom Tromey * gdb.ada/py_taft.exp: New file. * gdb.ada/py_taft/main.adb: New file. * gdb.ada/py_taft/pkg.adb: New file. * gdb.ada/py_taft/pkg.ads: New file. --- gdb/python/py-type.c | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'gdb/python') diff --git a/gdb/python/py-type.c b/gdb/python/py-type.c index e8af6f6..134f76d 100644 --- a/gdb/python/py-type.c +++ b/gdb/python/py-type.c @@ -1334,6 +1334,17 @@ type_to_type_object (struct type *type) { type_object *type_obj; + try + { + /* Try not to let stub types leak out to Python. */ + if (TYPE_STUB (type)) + type = check_typedef (type); + } + catch (...) + { + /* Just ignore failures in check_typedef. */ + } + type_obj = PyObject_New (type_object, &type_object_type); if (type_obj) set_type (type_obj, type); -- cgit v1.1
