Bug 208399 – ResourceLoadStatistics: Enable cookie blocking and the Storage Access API in ephemeral sessions

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[John Wilander]

Since full third-party cookie blocking is stateless, it can now be enabled in ephemeral sessions. User interaction as a gate for calling the Storage Access API can be captured in an ephemeral fashion as well to allow authenticated embeds. We should enabled these features.

I think you might have left a backtrace by accident, but otherwise looks great! R=me

Did you mean to leave this in?

Nope. And I had removed removed it but not saved the file before uploading.

Thanks for the review! I'll wait for green light on the ios-wk2 bot before putting it on the queue.

We got one curious layout test crash with this trace:

Looks like something is not happy when suspending. While that might be unrelated, I'll have to look at suspend() and resume() for ephemeral sessions before landing.

Then there's an API test that failed at least once on the api-ios bot: WKWebView.InitializingWebViewWithEphemeralStorageDoesNotLog

It does not fail on my Mac so I may have to reproduce in a simulator or on a device to see what's logging.

I just realized that the logging is most probably that stray WTFReportBacktrace() call.

The test case editing/async-clipboard/clipboard-change-data-while-getting-type.html does not fail on my Mac.

[John Wilander]

I had a conversation with Chris Dumez this morning on how to handle suspend/resume. Easy to do. Will add it to the patch I land.

Why are we reusing this bug for a small follow-up fix? This bug used to track a major change and now it looks like a one-liner.

webkit-patch upload automatically obsoletes previous attachments, which I undid making it clear that this is a followup fix to a big change.
