Status: RESOLVED INACTIVE

(Core :: General, defect)

Description

And the strange thing is that there are many XUL elements in the collected cycles
http://mozilla.pettay.fi/m.svg (zoom in and move mouse over objects)

Ahaa, I had error console open, and I *think* it is actually it causing lots of garbage when
showing only messages.

Comment 2

[Boris Zbarsky [:bzbarsky]]

Is that SVG file creating lots of error console entries?

Comment 3

[Olli Pettay [:smaug][[e-mail]]]

No. This bug was originally about http://www.mako.co.il creating lots of garbage, 
but is was http://www.mako.co.il causing lots of error console messages, and error
console creates then lots of garbage.

Comment 4

[Boris Zbarsky [:bzbarsky]]

OK.  Isn't that expected?  If the page is creating tons of messages and the console only shows 300 or whatever, then you'd get garbage from older entries....

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

It is perhaps expected, but not needed. We could easily cache some entries.

Comment 7

[Olli Pettay [:smaug][[e-mail]]]

bug 634444 is about js eng.

Comment 8

[Nicholas Nethercote [inactive]]

Yeah, and bug 634444 is only relevant when javascript.options.strict is enabled, and the memory in question is malloc/free memory, not GC heap memory.

Comment 9

[Jens Stutte [:jstutte]]

Do you think this is still relevant? And if so, probably more an enhancement?
