From 880d1e40c771e4a389d0b29bf196b50f1b696ea9 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Thu, 21 May 2015 00:45:26 +0200 Subject: gdb: Don't call tui_enable too early. Calling tui_enable too early in tui_layout_command can leave the tui in an enabled state if the user has entered an invalid layout name. Instead postpone the call to tui_enable until later in tui_set_layout_for_display_command just before the layout is changed. gdb/ChangeLog: * tui/tui-layout.c (tui_layout_command): Move call to tui_enable into ... (tui_set_layout_for_display_command): ...here, before calling tui_set_layout. Only set the layout if gdb has not already entered the TUI_FAILURE state. --- gdb/tui/tui-layout.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) (limited to 'gdb/tui') diff --git a/gdb/tui/tui-layout.c b/gdb/tui/tui-layout.c index e3993ab..abd9810 100644 --- a/gdb/tui/tui-layout.c +++ b/gdb/tui/tui-layout.c @@ -443,7 +443,12 @@ tui_set_layout_by_name (const char *layout_name) else status = TUI_FAILURE; - tui_set_layout (new_layout); + if (status == TUI_SUCCESS) + { + /* Make sure the curses mode is enabled. */ + tui_enable (); + tui_set_layout (new_layout); + } } xfree (buf_ptr); } @@ -492,9 +497,6 @@ extract_display_start_addr (struct gdbarch **gdbarch_p, CORE_ADDR *addr_p) static void tui_layout_command (char *arg, int from_tty) { - /* Make sure the curses mode is enabled. */ - tui_enable (); - /* Switch to the selected layout. */ if (tui_set_layout_by_name (arg) != TUI_SUCCESS) warning (_("Invalid layout specified.\n%s"), LAYOUT_USAGE); -- cgit v1.1
