Cannot change --max-old-space-size

[richard-keller-olivia]

Hello,

I am trying to adjust the node heap limit of my app running on bytenode, but I couldn't.

Steps to reproduce:

Create a test.js file:
console.log(`node heap limit = ${ require('v8').getHeapStatistics().heap_size_limit / (1024 * 1024) } Mb`)

Execution using node:
node test.js
Output
node heap limit = 2096 Mb

Execution using node with --max-old-space-size:
node --max-old-space-size=7500 test.js
Output
node heap limit = 7548 Mb

Execution using bytenode:
node --max-old-space-size=7500 node_modules/bytenode/lib/cli.js ./test.jsc
Output
node heap limit = 2096 Mb

Execution using bytenode sending --max-old-space-size:
node node_modules/bytenode/lib/cli.js ./test.jsc --max-old-space-size=7500
Output
node heap limit = 2096 Mb

So my next attempt was to fork a process sending --max-old-space-size on execArgv:

console.log(`node heap limit = ${ require('v8').getHeapStatistics().heap_size_limit / (1024 * 1024) } Mb`)

const cluster = require('cluster');
if (cluster.isMaster) {
  cluster.setupMaster({
    execArgv: ['--max-old-space-size=7500'],
  });
  cluster.fork();
}

node test.js
Output:

node heap limit = 2096 Mb
node heap limit = 7548 Mb

If I execute the same code using bytenode:

node heap limit = 2096 Mb
test.jsc:1

This should work:

node --max-old-space-size=7500 -r bytenode test.jsc

Given that bytenode is installed locally.

This bug should be fixed in cli.js. Thank you for reporting.
