Since the big tui rewrite (adding dynamic layouts) it is no longer true that there is a tui_win_info object for every window at all times. We now only create a tui_win_info object for a particular window, when the window is part of the current layout. As a result, if we have a tui_win_info pointer, then the window must be visible inside tui_set_focus_command (this function calls tui_enable as its first action, which makes the current layout visible). The gdb.tui/tui-focus.exp test script exercises this area of code, and doesn't trigger the assert, nor do any of our other existing tui tests. --- gdb/tui/tui-win.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/gdb/tui/tui-win.c b/gdb/tui/tui-win.c index 9c088899817..4fc8e7a4503 100644 --- a/gdb/tui/tui-win.c +++ b/gdb/tui/tui-win.c @@ -720,8 +720,11 @@ tui_set_focus_command (const char *arg, int from_tty) if (win_info == NULL) error (_("Unrecognized window name \"%s\""), arg); - if (!win_info->is_visible ()) - error (_("Window \"%s\" is not visible"), arg); + + /* If a window is part of the current layout then it will have a + tui_win_info associated with it and be visible, otherwise, there will + be no tui_win_info and the above error will have been raised. */ + gdb_assert (win_info->is_visible ()); if (!win_info->can_focus ()) error (_("Window \"%s\" cannot be focused"), arg);
