Regression(r253224) No longer able to prevent a tab from closing via the beforeunload prompt
https://bugs.webkit.org/show_bug.cgi?id=206366
<rdar://problem/58537467>
Reviewed by Geoffrey Garen.
Source/WebKit:
Change is covered by new API test.
* UIProcess/API/Cocoa/WKWebView.mm:
(-[WKWebView _tryClose]):
(-[WKWebView _isClosed]):
* UIProcess/API/Cocoa/WKWebViewPrivate.h:
Add new _tryClose / _isClosed SPI on WKWebView in order to write an API test to cover
the change.
* UIProcess/WebPageProxy.cpp:
(WebKit::WebPageProxy::runBeforeUnloadConfirmPanel):
In WebPageProxy::tryClose(), we start a timer before sending the TryClose async IPC to the
WebProcess. We would then stop the timer when receiving the response to the TryClose IPC.
If the timer fires, we would forcefully close the page. The issue was that before answering
the TryClose IPC, the WebContent process would send a sync RunBeforeUnloadConfirmPanel IPC
to the UIProcess to show the confirmation prompt, and this would fail to stop the timer.
WebPageProxy::runBeforeUnloadConfirmPanel() would spin a nested run loop to show the prompt
and we would time out while showing the prompt.
Tools:
tryClose_timeout_fix
* TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* TestWebKitAPI/Tests/WebKit/beforeunload.html: Added.
* TestWebKitAPI/Tests/WebKitCocoa/ModalAlerts.mm:
