Comment 1

[Sandor Molnar[:smolnar]]

@whimbo, could you take a look at these failures
started to fail after bug 1736323 landed.

Comment 2

[Julian Descottes [:jdescottes]]

Will take a look today

Comment 3

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Please also check if bug 1739066 and bug 1739074 It's uncommon to see new Marionette failures which have been observed several times for a day.

Comment 4

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Yes, those seem to be also related.

Comment 5

[BugBot [:suhaib / :marco/ :calixte]]

Set release status flags based on info from the regressing bug 1736323

Comment 6

[Julian Descottes [:jdescottes]]

Started adding some logs, as expected we timeout before waitForNavigationCompleted in newSession. Meaning we get a webprogresslistener with isLoading set to true, but we never actually get the navigation events.

Comment 7

[Julian Descottes [:jdescottes]]

It's not that surprising because the pattern we use is racy by nature.

     if (browsingContext.webProgress.isLoadingDocument) {
        await navigate.waitForNavigationCompleted(this, () => {}, {
          loadEventExpected: true,
          unknownState: true,
        });
      }

In the parent process we detect that we have a load, but then we will communicate to the content process in order to add load listeners. So before the listeners can be added, the navigation might complete and we might never receive any load event.

Either we need to fully monitor the load from the parent process, or we need to be a bit more careful in navigate.js in case we pass unknownState to true. I think we should check the state of the document (or of the webprogresslistener?) in the content process before expecting a load event.

Comment 14

[Henrik Skupin [:whimboo][⌚️UTC+2]]

I discussed the topic with Julian yesterday and he will try out some options. If we cannot find the right solution until afternoon today I will go ahead and request a backout of bug 1736323 given that this new hang in WebDriver:NewSession is way more severe.

Comment 21

[Julian Descottes [:jdescottes]]

Renewing my need-info: will have to uplift this and Bug 1736323 to beta. Uplifting patches from both bugs will allow to reuse the same patches as the ones used against central. Let's wait to see if the current patch sticks.

Bug 1739008 - [marionette] Monitor navigation using the webprogresslistener for NewSession

Beta/Release Uplift Approval Request

• User impact if declined: Users of marionette/geckodriver (eg selenium webdriver users) are exposed to a race condition that can lead to sessions created too early, and therefore making their scripts fail. Hitting this race condition became much more frequent after Bug 1735500 landed in Firefox 95.

We fixed it over Bug 1736323 and Bug 1739008 (this bug), which only landed in 96. We should uplift both patches to 95 to avoid issues due to Bug 1735500.

• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: Bug 1736323
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Low risk as it only affects marionette users and is changing the logic to create new sessions in order to wait for a load in case we are creating a session when a document is not loaded.
  The new session logic is extensively tested and relied upon in many tests and test suites.
• String changes made/needed:

Comment 27

[Ryan VanderMeulen [:RyanVM]]

Can we get a rebased patch for ESR now that the regressing patch was uplifted there?

Comment 28

[Henrik Skupin [:whimboo][⌚️UTC+2]]

I'm not sure if we need an uplift here. It regressed because of a feature (bug 1735500) that landed for Firefox 95. My try build hasn't shown any failing tests for MacOS on esr91.

Comment 29

[Ryan VanderMeulen [:RyanVM]]

Attachment: bug_1739008_esr91_backport.patch

[Approval Request Comment]
If this is not a sec:{high,crit} bug, please state case for ESR consideration: This fixes a regression from Bug 1736323 which was just uplifted to ESR91
User impact if declined: user impact should be relatively low, this issue mostly leads to intermittent failures and pollutes our CI
Fix Landed on Version: 95 (landed in 96 but was uplifted)
Risk to taking this patch (and alternatives if risky): Low, same comment as for the beta uplift: Only affects marionette users and is changing the logic to create new sessions in order to wait for a load in case we are creating a session when a document is not loaded. The new session logic is extensively tested and relied upon in many tests and test suites.

See https://wiki.mozilla.org/Release_Management/ESR_Landing_Process for more info.

Note that you triggered the wdspec jobs for MacOS only. But the two failures that we got are from Linux. So you may want to extend to maybe all desktop platforms.
