192198 - Browser hangs on this page apparently due to endless loop

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

[Brian 'netdragon' Bober]

I have no idea what makes it freeze. Just something to do with changes I made to
the divs with id "handleon" and "handleoff". Maybe someone can reduce the
testcase I'm about to attach.

Attachment: Let's see if I can figure out what causes this.

Attaching this in case I can't make a better testcase.

Attachment: Final testcase

Notice that if I changed the loop with while(1) {} it gave me a warning.But
this didn't:
	while (1)

	{

		var part1 = "";

		var part2 = "";

		val = part1 + " " + part2;

	}

I thought the bug for endless loops in javascript was fixed.

Firefox PR came out of the hang in 25 seconds with a warning and an option to
stop the script.  No data was lossed and pages that were loading continued to
load after the ordeal.

Interesting. I can't figure out if this should be considered fixed or not. Is 25
seconds too long? :-/

In the latest build (2005062105) it gave me a warning after about 3 seconds on a
3GHz P4 machine.
maybe it should be marked as fixed?

Message comes up after ~10 secs in FF 2.0 on WinXP Home
It seems fixed enough.

Slow script dialog comes up after ~10 seconds.
