lib: do not crash using workers with disabled shared array buffers #41023

BridgeAR · 2021-11-29T21:01:08Z

This allows the repl to function normally while using the
--no-harmony-sharedarraybuffer V8 flag.

It would be great if you could add a comment to these explaining why it's necessary since I don't think it's going to be obvious to someone reading the code. Especially the first occurrence that does not reference SAB directly.

I missed the prior work by @codebytere #39718. I might also have found the issue that blocked the PR from being merged. I'll try that later on.

I unblocked this again to move it forward. @jasnell @tniessen are you fine landing this instead of waiting for #39718?

This allows the repl to function normally while using the `--no-harmony-sharedarraybuffer` V8 flag. It also fixes using workers while using the `--no-harmony-atomics` V8 flag.

@BridgeAR is this still something you want to move forward? We still float the patch so it's definitely still useful to Electron!

BridgeAR · 2023-02-17T18:57:12Z

@codebytere I just rebased the branch and started the CI to land this :)
