714817 - No unresponsive dialog with mootools class and firebug

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Trev]

Attachment: infinite_recursion.html - This will lock up the browser

User Agent: Mozilla/5.0 (Ubuntu; X11; Linux x86_64; rv:12.0a1) Gecko/20120103 Firefox/12.0a1
Build ID: 20120103035128

Steps to reproduce:

I have a webpage that just loops through all the items that are added to the boolean object by mootools.  It runs for a long time, freezes the browser, eats up a lot of memory, and never shows the "unresponsive dialog".  If I don't use a mootools class (so the functions are just global functions), I get the "unresponsive dialog".

You also need Firebug enabled with the script debugging turned on.

I'm attaching both the scripts.  Just click "Kill Me" to run it.

Chances are, this confuses the "which script is running" state so we think that it's not just one script that's running forever.

Is this Bug still relevant or can it be closed by now?

I don't know; I didn't file this bug... That said, try running the testcases with devtools enabled and see what happens?
