Comment 36

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

This fails very frequently. Alexandre, any recommendations on the next step here?

Comment 37

[Alexandre Poirot [:ochameau] [PTO back August 21]]

This may relate to bug 1603190.
A few bugs got fixed in bug 1633703, but that may not have been enough.

Julian, could you confirm if that relates to windowless service worker?

I'm wondering if bug 1603190 is really worth all the time spent. We aren't only sparing DevTools engineer's time here, but also sherrifs's one.
If that's the case, we should report all the time spent trying to debug this known to be bad feature.
And possibly revisit the decision to enable this.

Comment 38

[Julian Descottes [:jdescottes]]

It's very likely related to the same issue. We could disable dom.ipc.processPrelaunch.enabled in more tests I guess.
Will look more tomorrow.

Comment 43

[Julian Descottes [:jdescottes]]

I'll try to see how many tests are opening the debugger without setting dom.ipc.processPrelaunch.enabled to false. Looking at the duplicates here, not all failures seem to be in devtools/client/framework/test/ so we can't simply flip the preference for the framework/test/browser.ini suite.

Each debugger test without the pref should fail in https://treeherder.mozilla.org/#/jobs?repo=try&revision=eb5917ec43bdfab987fc8e83a0c722a99f609a99, after that we can see if we flip the pref individually on each test or do something different.

Keeping the ni.

Comment 50

[Julian Descottes [:jdescottes]]

It still seems to fail pretty frequently.

The situation might improve with Bug 1621337 for some tests.
For instance I could see that browser_metrics_debugger.js was fixed with my patches from Bug 1621337, because the debugger now properly waits for service workers when initializing.
