Used devmonkey22/electron-renderer-leak as a base.
The main process registers a protocol app:// so that the SharedWorker
will actually be shared.
Two windows should open and each post a message to the SharedWorker. One window should say "Result: 0" and the other should say "Result: 1"
Click the button in each window to post a message.
If it's working (as it is in Electron 6), a message should appear that says "Result: N", where N is the number of times a message has been posted.
If it's not working, the message will say "No clicks yet."
There is a second button that says "Create Worker with Data URL", which creates a SharedWorker with a data URL.
Clicking this button in Electron 6 creates a functional worker.
Clicking this button in Electron 7 crashes the renderer.
If you edit main.js to disable nodeIntegrationInWorker, the SharedWorker object is created,
but the worker is still non-functional.
Tested with:
- Ubuntu 18.04.2, Windows 10
- Electron 7.0.0-beta.6 (broken)
- Electron 6.0.12 (working)
- nodejs v10.16.0
