Description
Version
v17.7.1
Platform
Linux 5.13.0-30-generic #33~20.04.1-Ubuntu SMP Mon Feb 7 14:25:10 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Subsystem
worker_threads
What steps will reproduce the bug?
const { MessageChannel } = require('worker_threads');
const ch = new MessageChannel()
ch.port1.onmessage = () => console.log('hey');
ch.port2.close();
ch.port2.postMessage('asdf');
How often does it reproduce? Is there a required condition?
Consistently in v17.7.1, v16.14.0 and v14.19.0.
What is the expected behavior?
The program should not log anything, since port2
is closed right before the call to postMessage
.
What do you see instead?
The program does log hey
.
Additional information
For whatever is worth, both in Chrome (Chromium 98.0.4758.102, V8 9.8.177.11) and Firefox (97.0.2), the message never arrives.
