Comment 6

[Julian Descottes [:jdescottes]]

Took a look at the current failures, seems like we have three main offenders:

• devtools/client/framework/test/metrics/browser_metrics_debugger.js : 27 failures
• devtools/client/framework/test/browser_toolbox_view_source_02.js : 6 failures
• devtools/client/framework/test/browser_source_map-init.js : 6 failures

All the other tests failed 3, 2 or 1 time only. I really think Bug 1621337 should help, as it means the debugger will wait until it has retrieved serviceworker targets before resolving. But I'm not sure when it can land since it's not fully reviewed.

I propose to land a temporary fix for those three tests and keep the bug as leave open to track the evolution.

I don't have any updates, we've been working on https://bugzilla.mozilla.org/show_bug.cgi?id=1621338 which might fix some of those.

Comment 17

[Julian Descottes [:jdescottes]]

Bug 1621338 didn't seem to help much. Looking at recent failures, I see a lot of them are for browser_toolbox_tool_remote_reopen.js with the following stack:

request@resource://devtools/shared/protocol/Front.js:256:14
generateRequestMethods/</frontProto[name]@resource://devtools/shared/protocol/Front/FrontClassWithSpec.js:47:19
listAllWorkerTargets/listChildWorkers/processWorkers<@resource://devtools/client/fronts/root.js:175:40
Async*listChildWorkers@resource://devtools/client/fronts/root.js:166:19
async*listAllWorkerTargets@resource://devtools/client/fronts/root.js:185:7
listAllServiceWorkers@resource://devtools/client/fronts/root.js:59:20
async*updateWorkers@resource://devtools/client/application/initializer.js:102:65

And while this is worker-related, this is a different codepath from the one touching the debugger (which is the one we have been trying to improve).
We can probably to land a fix dedicated to the application panel.

Comment 19

[Julian Descottes [:jdescottes]]

Actually it seems that all the failures since Bug 1621338 landed are application panel related, so hopefully we did get rid of the debugger issue and just need to fix the application panel now.

I think my last patch should fix the problem, but it hasn't been reviewed yet.

Belén, can you take a look at this patch or should I redirect?
