This might be connected to bug 1618546 ? I assume that in this pointer cascade is hiding a null pointer in some cases. Should we do less asserts and more if here?

This seems to be a regression from here added by bug 1618546.

And I see several places where we already check mScope before we use it, like here.

But here we have only an assert in place, I would assume (without deeper insight in the lifecycle) that we should check mScope before any usage rather than just asserting in debug.

Reading it all over again, I agree - it does seem like it's possible that data->mScope is null for freezing and thawing the worker...

Attached file Bug 1632036 - check for null global when freezing/thawing WorkerPrivate r?#dom-workers-and-storage-reviewers — Details

Apply pointer guidelines to ClientSource getter.
When freezing/thawing WorkerPrivate, check if the client/global is null. It seems possible that the client is null because the WorkerPrivate can remain registered to the RuntimeService even if it failed to create its global, and freezing/thawing is done through the RuntimeService. The other two callsites to get the client won't execute unless CompileScriptRunnable successfully creates the client.

Is there a user impact to this bug which would make us want to consider uplifting to ESR78 or is this unlikely to hit in the real world?

I am not sure if it is likely to hit this in the real world in a situation where the content process isn't defunct anyway. However, I am not that familiar with the Service Workers code, so maybe Andrew could make the final call on this?

This should be uplifted to ESR78. I'll fill the form.

Bug 1632036 - check for null global when freezing/thawing WorkerPrivate r?#dom-workers-and-storage-reviewers

ESR Uplift Approval Request

If this is not a sec:{high,crit} bug, please state case for ESR consideration: This bug corrects an edge case crash where a Worker is spawned very late into the shutdown process. Besides eliminating the crash, as we do expect to continue to uplift Worker and Service Worker fixes over the life of ESR78, it's appropriate to attempt to maintain related code consistency. (In particular, this patch introduces MutableClientSourceRef which is certain to be a dependency of future uplifts.)
User impact if declined: Rare crashes at shutdown.
Fix Landed on Version: 80
Risk to taking this patch: Low
Why is the change risky/not risky? (and alternatives if risky): Additional safety checks and a thorough review.
String or UUID changes made by this patch: none
