setInterval sniffer

This no longer works

If you relly want to see this extension, consider sponsoring my projects.

Install

From Chrome App Store or from the repository:

• chrome://extensions/
• Turn on "Developer mode" checkbox
• Click "Load unpacked extension..." button
• Select setInterval-sniffer/chrome folder

How does it work

The sniffer monkey patch (extend without altering the original source code) setInterval method:

var originalSetInterval = window.setInterval;
window.setInterval = function(fn, time) {
	var id = originalSetInterval(fn, time);
	post({
		functionName: 'setInterval',
		fn: fn.toString(),
		id: id,
		time: time
	});
	return id;
};

Roadmap

• Don't stop sniffing on page reload
• Button to kill an interval in Timers panel
• Add stacktrace data using the technic from captureCalls.js
• Display setTimeout too, visually separate them from setInterval
• Make it prettier
