Sometimes the browsingContext.contextCreated event isn't getting sent out for the target URL but for about:blank:

The question here is why the frame isn't getting loaded. Maybe it's related to bug 1760291 and wptserve fails to send the data here again? Nevertheless the timeout that we have here for this debug build is probably too short as well and as such we abort waiting for an initial navigation.

See also a discussion about the removal of the URL field:
https://github.com/w3c/webdriver-bidi/issues/220

Severity: -- → S3
Priority: -- → P3

Live events (when a new browsing context is actually created) should actually always be sent out immediately. That means that no navigation has actually be taken place and as such the URL should always be about:blank.

Putting bug back for triage so that we might at least have it as P2.

Severity: S3 → --
Priority: P3 → --
Summary: "browsingContext.contextCreated" events for frames are sometimes send out for "about:blank" → Live "browsingContext.contextCreated" events have to be sent out with an URL of "about:blank"

This is blocked on the wdspec test updates which will be synced via bug 1777173.

Bug 1775141 - [webdriver-bidi] Send live "browsingContext.contextCreated" events with "about:blank" as URL.

ESR Uplift Approval Request

  • If this is not a sec:{high,crit} bug, please state case for ESR consideration: The WebDriver BiDi specification has been updated and this patch fixes an intermittent failure as well that we would also like to see fixed on 102ESR which will still exist for quite some time.

With uplifting this also needs the patch on bug 1777173 uplifted before.

  • User impact if declined: The browsingContext.contextCreated event will be delayed and most of the times emits the target URL of the newly opened tab within the payload but not about:blank. As such intermittent unexpected behavior can occur.
  • Fix Landed on Version: 104
  • Risk to taking this patch: Low
  • Why is the change risky/not risky? (and alternatives if risky): There is a low risk because the code that awaits the new tab to be finished with the initial navigation has only been removed.

This doesn't graft cleanly to ESR102. Please rebase and re-request when you get a chance.

Attachment #9284599 - Flags: approval-mozilla-esr102?

I rebased the patches and pushed to try:
https://treeherder.mozilla.org/jobs?repo=try&revision=b26b8360449cb4eae9f3e9cddea07e44a84a4664

Please note that for the 102 branch I had to slightly modify the manifest file for bug 1777173 because our script.evaluate implementation isn't available there yet and as such both tests that open a new browsing context via window.open will still pass.

Julian, can you please check if the updated patches look fine to you? Thanks.

Flags: needinfo?(jdescottes)

Thanks Henrik, the rebased patches all look correct to me.
