src: support WeakReference, diagnostics_channel and net in the snapshot #44193

joyeecheung · 2022-08-09T18:07:19Z

The first commit comes from 44192.

The support for net isn't complete, for example there is still work to be done to make the DNS code snapshotable. But it's already alright to snapshot sockets that have never fired DNS requests and are not actively open.

+runTest(fixtures.path('snapshot', 'weak-reference.js'));
+runTest(fixtures.path('snapshot', 'weak-reference-gc.js'));


I am not 100% sure that we should test this, because technically V8 does not guarantee that the object would actually be GC'ed after a gc() call, but we already have an internal test for WeakReference and it has not come up as flaky so far so 🤷.

Marking this as blocked since it depends on #44192. Please feel free to unmark it.

Probably blocked on #44203 too unless we want to skip the weak reference test in the debug build..

Move util::WeakReference to a separate header and implement {de}serialization for it to be snapshotable.
