Revision 4e5f09f89e6f1976dd49a57ba46cd447c7e19a1e authored by Alex Moshchuk on 13 April 2018, 15:22:14 UTC, committed by Chromium WPT Sync on 13 April 2018, 15:22:14 UTC
Changes from original attempt at https://crrev.com/c/999182: - fix flakiness in two additional ChromeOS login tests - fix CSP WPT tests to not depend on ordering between iframe's onload and postMessage - see https://crbug.com/832319. Previously, we sent the IPC to forward a cross-process postMessage immediately. This caused a behavioral difference from the same-process case where the postMessage is always scheduled. Namely, in a scenario like this: frame.postMessage(...); doSomethingThatSendsIPCsToFrame(frame); the IPCs from JS following the postMessage would've been ordered incorrectly, causing |frame| to see their side effects after the postMessage dispatch in the cross-process case, whereas they would be seen before the postMessage dispatch in the same-process case. One example of this is frame.focus(), and another is a frame element onload event (dispatched via FrameHostMsg_DispatchLoad) arriving after a postMessage dispatched from an inline script while the frame was still loading. To resolve these ordering concerns, this CL changes cross-process postMessage to do a PostTask on the sender side before sending the message to the browser process. This improves the current state of the world, but does not yet achieve a perfect match for the IPC ordering in the same-process case - see discussion on the bug.
