I wish we would have the nserror stack here. Maybe bug 1591161 will help with that in the future.

[Henrik Skupin [:whimboo][⌚️UTC+1]]

(In reply to Andreas Tolfsen ❲:ato❳ from comment #1)

I wish we would have the nserror stack here. Maybe bug 1591161 will help with that in the future.

No it won't. That is all what we get for this error. I have seen that already while implementing the test but thought I got it removed. I never was able to see it on my machine. Checking the intermittent failures I can see why... it happens very rarely on MacOS but mostly on Linux and Windows. So I will have to use my older Linux machine to reproduce it.

The underlying problem here is somewhat related to content code this test runs. My speculation is that the test continues even with the await keyword added for checkPromise. And SpecialPowers.spawn or the progress listener, which is still active, somewhat get in trouble returning the Promise. Due to the terrible error details it's far away from being easy to understand. So lets see if I can find out something today.

Comment 4

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Something here is really bogus with SpecialPowers.spawn(). Maybe it is related to the internal async behavior:

/* Any copyright is dedicated to the Public Domain.
 * http://creativecommons.org/publicdomain/zero/1.0/ */

"use strict";
  
const TEST_PAGE = "data:text/html,<div>test</div>";

add_plain_task(async function() {
  const finished = SpecialPowers.spawn(
    gBrowser.selectedBrowser,
    [],
    async () => {
      await new Promise(resolve => content.setTimeout(resolve, 4000));
    }
  );

  const browser = gBrowser.selectedTab.linkedBrowser;
  const loaded = BrowserTestUtils.browserLoaded(browser, false, TEST_PAGE);
  BrowserTestUtils.loadURI(browser, TEST_PAGE);
  await loaded;

  await finished;
  ok(true);
});

With this code snippet for a browser chrome test I can always produce this failure. Note that there is nothing related to the remote agent at all.

Kris, any idea what this could be?

Comment 5

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Sorry, but what I added here is actually not true. I missed the return statement in the inner task, and as such it was working. Once I add it back the same problem is back.

As it looks like the problem is the inner async task, which doesn't seem to be allowed, even a couple of browser chrome tests like browser_test_doc_creation.js make use of it.

When I just return the promise without calling await it seems to work all fine. So I will fix this failure for now, and when Kris agrees that the task cannot be async, we should update a couple of tests.

Comment 6

[Kris Maglione [:kmag]]

The problem is that SpecialPowers.spawn tasks are limited to the lifetime of an inner window, but the test navigates the window the task was spawned in between the time it's launched and the time it completes.

Comment 7

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Hm, so I have to setup a webprogress listener on the docshell to observe the load flags:
https://searchfox.org/mozilla-central/source/remote/test/browser/network/browser_setCacheDisabled.js

To catch all of those I have to register it before I load the page. Is there another way in doing that? Do you know? I tried to have the listener in the parent process but I was not able to get it working. Thanks!

Comment 8

[Henrik Skupin [:whimboo][⌚️UTC+1]]

What I wonder is that this is basically an intermittent failure and not happening that often. Given your explanation I would assume that it is always failing. Maybe it's just that spawning the task via SpecialPowers takes a bit of time, and due to the async nature of checkLoadFlags we already started the page load so that the task is run on the new inner window?

I don't really know. There sure must be some API to load scripts in child process in a way which isn't bound to the inner windows.
But looks like the APIs have changed recently.

The problematic API here is actually SpecialPowers.spawn(). Most of the tests have been converted to use that API instead of ContentTask.spawn(). But not all can be converted right now due to:

(In reply to Kris Maglione [:kmag] from bug 1596918 comment #0)

That said, there are still cases where have ContentTask.spawn calls which can't be converted to SpecialPowers.spawn. The main difference at this point is the lifetime of the task, where ContentTask.spawn is bound to the lifetime of a frameloader, and may persist across same-process navigations, and SpecialPowers.spawn is bound to the lifetime of a window global, and may not. In general, those kinds of tasks should be considered deprecated, and should be rewritten in such a way as to be agnostic to whether a navigation maintains the same docShell/process as the previous document. But that is a nontrivial amount of work.

So to fix this intermittent I will revert back to ContentTask.spawn() for now and figuring out how to convert it to SpecialPowers.spawn() at a later time.
