Historically, we've had a bunch of complicated machinery to delay the call to CleanUp() for modal dialogs, since we needed to harvest the return value after the window closed. But in the current world we don't actually null out mReturnValue in CleanUp() at all, which presumably happened sometime around the time mReturnValue became cycle-collected. So this stuff can just go away. \o/ That simplification is righteous in itself. But it also fixes the bug here as- filed. When the user quits while a modal dialog is currently being displayed, a failure code ends up bubbling up through windowWatcher to the OpenInternal call in nsGlobalWindow::ShowModalDialog, which means that we're unable to do our delayed CleanUp() call for the outer modal window. At first it seemed like a hard problem to solve, but with the above it becomes trivial. |
