src: do proper error checking in `AsyncWrap::MakeCallback` #21189

addaleax · 2018-06-07T13:28:24Z

At least one method on a native object is added as a getter,
namely MessagePort.prototype.onmessage. When a MessagePort
attempts to call this method from C++ in response to receiving
data, it will first invoke that getter and then call the function.

Since worker.terminate() interrupts execution, this means
that the getter may fail (without being faulty code on its own).
This means that at least one test exercising these methods in
combination has been flaky and could have crashed, because
we did not actually check that the getter returns a value
so far, resulting in dereferencing an empty Local.

The proper fix for this is to use the non-deprecated overload
of Get() and check the result like we should be doing.
Also, as a (related) fix, don’t crash if the method
is not a function but rather something else, like a getter
could provide.

+    // Due to V8’s error handling mechanisms, this will not show up as an error
+    // in the common case, which is that this is outside of any JS frame.
+    // So, the exception here is mostly just there to fulfill the
+    // `MaybeLocal<>` API contract.


Btw, this is something I’d like to fix by adding a verbose TryCatch around the event loop (if I can make it work – not sure about that). But that would be a semver-major change.

addaleax · 2018-06-07T13:53:09Z

@apapirovski Could you take another look? I’ve had to make a few changes because the test wasn’t really testing what it was supposed to test… left out the new error for now, it looks like that would have to be part of the semver-major change I alluded to above.

Excellent description and good find!

@benjamingr The credit for finding this really goes to Anatoli here ;)

Ok, now.
