From 92256134f3e5557dcc321c63c48e8175ea90ca27 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 24 Apr 2017 20:59:37 -0600 Subject: [PATCH] Allow C-c to work in backtrace in more cases PR cli/17716 notes that it is difficult to C-c (or "q" at a pagination prompt) while backtracing using a frame filter. One reason for this is that many places in py-framefilter.c use RETURN_MASK_ALL in a try/catch. This patch changes these spots to use RETURN_MASK_ERROR instead. This is safe to do because this entire file is exception safe now. gdb/ChangeLog 2018-03-26 Tom Tromey PR cli/17716: * python/py-framefilter.c (py_print_type, py_print_value) (enumerate_args, py_print_args, gdbpy_apply_frame_filter): Use RETURN_MASK_ERROR. --- gdb/ChangeLog | 7 +++++++ gdb/python/py-framefilter.c | 22 +++++++++++----------- 2 files changed, 18 insertions(+), 11 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5cc8d9ef9c5..9b29e6e9ff7 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2018-03-26 Tom Tromey + + PR cli/17716: + * python/py-framefilter.c (py_print_type, py_print_value) + (enumerate_args, py_print_args, gdbpy_apply_frame_filter): Use + RETURN_MASK_ERROR. + 2018-03-26 Tom Tromey * python/py-framefilter.c (enumerate_args): Use diff --git a/gdb/python/py-framefilter.c b/gdb/python/py-framefilter.c index dcac42df8ec..28d5c37b25b 100644 --- a/gdb/python/py-framefilter.c +++ b/gdb/python/py-framefilter.c @@ -215,7 +215,7 @@ py_print_type (struct ui_out *out, struct value *val) type_print (value_type (val), "", &stb, -1); out->field_stream ("type", stb); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -255,7 +255,7 @@ py_print_value (struct ui_out *out, struct value *val, { type = check_typedef (value_type (val)); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -282,7 +282,7 @@ py_print_value (struct ui_out *out, struct value *val, common_val_print (val, &stb, indent, opts, language); out->field_stream ("value", stb); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -497,7 +497,7 @@ enumerate_args (PyObject *iter, { annotate_frame_args (); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -553,7 +553,7 @@ enumerate_args (PyObject *iter, { read_frame_arg (sym, frame, &arg, &entryarg); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -586,7 +586,7 @@ enumerate_args (PyObject *iter, out->text (", "); out->wrap_hint (" "); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -622,7 +622,7 @@ enumerate_args (PyObject *iter, { out->text (", "); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -636,7 +636,7 @@ enumerate_args (PyObject *iter, { annotate_arg_end (); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -867,7 +867,7 @@ py_print_args (PyObject *filter, if (! out->is_mi_like_p ()) out->text (" ("); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -884,7 +884,7 @@ py_print_args (PyObject *filter, if (! out->is_mi_like_p ()) out->text (")"); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { gdbpy_convert_exception (except); return EXT_LANG_BT_ERROR; @@ -1336,7 +1336,7 @@ gdbpy_apply_frame_filter (const struct extension_language_defn *extlang, { gdbarch = get_frame_arch (frame); } - CATCH (except, RETURN_MASK_ALL) + CATCH (except, RETURN_MASK_ERROR) { /* Let gdb try to print the stack trace. */ return EXT_LANG_BT_NO_FILTERS; -- 2.30.2
