Child process not receiving messages when created with an --eval argument to child_process.fork #8944
Description
- Electron version: 1.6.3
- Operating system: macOS 10.12.3
In this example repository, I'm creating two child processes via child_process.fork, one using --eval and the other via a module path to a file containing essentially the same source as I'm evaling in the first case. The code is as follows:
const sourceToEval = `
console.log('starting child process 1')
process.on('message', m => console.log('child 1 got message', m))
console.log('waiting for messages in child process 1...')
`
const {fork} = require('child_process')
console.log('forking child process 1 (using --eval)')
const child1 = fork('--eval', [sourceToEval])
console.log('done forking child 1, sending message')
child1.send('hello from your parent')
console.log('forking child process 1 (using module path)')
const child2 = fork('./child')
console.log('done forking child r, sending message')
child2.send('hello from your parent')Expected behavior
I would expect to see output from both child processes on stdout of the parent when they receive messages.
Actual behavior
I only see output from the process forked with a module path.
