Patrick Palka 1e04046d0b Avoid race condition when handling a SIGWINCH signal ... The control variable win_resized must be cleared before responding to it. Otherwise there is a small window where another SIGWINCH might occur in between the handling of an earlier SIGWINCH and the clearing of win_resized, at which point win_resized would be set (again) by the signal handler. Shortly thereafter we would clear win_resized even though we only handled the earlier SIGWINCH but not the latest one. This chain of events is all avoided if we clear win_resized first. gdb/ChangeLog: * tui/tui-win.c (tui_async_resize_screen): Clear win_resized first before resizing the window. * tui.c (tui_enable): Likewise.		2015-05-13 11:53:28 -04:00
