There have been 93 total failures in the last 7 days (recent failure log).
Affected platforms are:

• linux1804-64 opt & debug, linux1804-64-asan, linux1804-64-ccov, linux1804-64-shippable, linux1804-64-tsan
• macosx1014-64-qr opt & debug
• windows10-64 debug & asan, windows10-64-qr debug & opt

Most of the failures seem to happen on linux at the moment.
Dave, could you please redirect this to someone who can take a look?

Comment 29

[Florian Quèze [:florian]]

Here's a profile of the passing test on my local Mac build: https://share.firefox.dev/3mhEoiy

I see that there are 2 TestUtils.waitForCondition calls that resolve immediately, and they are before the calls to SpecialPower.Spawn. The failure rate of this bug seems to have increased around the time of when I landed bug 1596165. Before that the waitForCondition calls never resolved in less than 100ms. There's likely a timing issue there.

[Dave Townsend [:mossop]]

Gijs, looks like you wrote this test, can you take a look or suggest someone else who can?

Comment 45

[:Gijs (he/him)]

This pattern of code which recurs several times in the test:

https://searchfox.org/mozilla-central/rev/2819d981824ad8a707885346d7ddb3bd3e077c9c/browser/modules/test/browser/browser_preloading_tab_moving.js#108-122

  let browser = newWin.gBrowser.preloadedBrowser;
  let tab = BrowserTestUtils.addTab(
    newWin.gBrowser,
    newWin.BROWSER_NEW_TAB_URL
  );
  is(
    tab.linkedBrowser,
    browser,
    "Preloaded browser is usable when opening a new tab."
  );
  await SpecialPowers.spawn(browser, [], function() {
    return ContentTaskUtils.waitForCondition(() => {
      return content.document.readyState == "complete";
    });
  });

is trying to wait for a loaded or loading browser document from a preloaded tab to be swapped into a newly created tab. The test is trying to verify that (a) this happens, and (b) that the new tab ends up with a loaded document. It can't use events for this directly because the browser's content might be loaded prior to being swapped, or it may load afterwards. It looks like the changes in bug 1596918 switched us from ContentTask to SpecialPowers, which already ran into issues which is why 1 spawn call has a blanket Cu.reportError catch - but the others do not. We could obviously add catch clauses to the 2 other spawns, but that's just wallpapering the problem.

Kris/Andrew: Why is the spawned task being destroyed, and how can we reasonably wait for this event if this kind of thing doesn't work? I'm assuming it's something like "the spawn call initially runs against about:blank and then we load the actual requested URI which swaps out content windows and aborts the spawn call" -- but then, why did that start happening 9 months ago, on non-fission tasks, and what is the "right" way to do this?

Sorry, I messaged Gijs (while he is away) on matrix, but didn't give a status update here. I've quickly looked into it and tried a few things but couldn't fix it. I'm busy with higher priority Fission work right now, but can probably look again when I have some time.

Sorry, I am probably not looking in the right rooms but I can't find your message on matrix (but it's been 2 weeks...). If there's a specific question I can help clarify or if you know the answers to some of the questions at the tail end of comment #45 then perhaps we can find a way of moving forward here :-)

Comment 58

[Kris Maglione [:kmag]]

The actor that handles the spawn task is tied to a specific inner window. It needs to finish executing before that window is destroyed. But the test doesn't wait for the correct inner window to be created before calling spawn, so it will sometimes wind up executing in the initial about:blank document, which will never have readyState == "complete"

How should it do that, ie how can you wait for an inner window being created in the child process from the parent, in a test? Are there other tests that do this "right"?

Usually with BrowserTestUtils.browserLoaded or openNewForegroundTab with waitForLoad: true (which is the default). You can also use a WebProgressListener, but that's more work.

This assumes that a load event will always follow; As I said in comment #45, I don't think that's the case, as we're testing that a preloaded browser is getting swapped in, and that browser may already be loaded, so browserLoaded would never resolve. It would race "the other way".

Can we wait for the inner window creation directly?

I don't see how that would make a difference from waiting for the load. If you get an inner window creation event, you'll get a load event.

You could always check the current URI of the WindowGlobalParent and use a WebProgressListener if it isn't what you want.

Attachment: Bug 1659101 - fix intermittent failure in browser_preoloading_tab_moving.js, r?jaws

See discussion in the last few comments on the bug. If we don't wait for the correct URL
to load in the browser, the SpecialPowers.spawn task can get aborted, which causes the
test to fail.
