67223 - JS profiler: need better data on anonymous content

Status: VERIFIED INVALID

(Core :: XPConnect, defect)

Description

[(not reading, please use [e-mail] instead)]

when I used the js profile (which has been very useful) I am losing data due to
anonymous content.

(at least, I think it is anonymous content)

Here's an example from the output

[1,9] anonymous() {306-317} {min 41, max 96 avg 70}

(http://www.mozilla.org/performance/jsprofiler.html for what those numbers
mean.)

any thing we can do to get better data?

That's not anonymous content, it's an unnamed function expression (lambda
expression).  The best we can do is give the line number extent of the function
expression -- is that what the numbers in braces tell?

In many cases, they are methods of a JS object (e.g., nsContextMenu.js).

[And by the way, I was doing some runs with this profiler and it's great!!]

yes, that's what the {a-b} tells you.

thanks for the tip, brendan.
