Dojo leaks in frames in IE

[sol@…]

Hey. It seem Dojo leaks in frames. When a page with Dojo is shown in a frame it seems dojo doesn't unload at all(?) or leaks for whatever other reason.

Simple case of just loading dojo.js with an empty page (with no other script) in a frame shows the memory leak. The leak is small (but still present) for referencing dojo in repository (not baked, when dojo.js is small), but is really a problem for built dojo (baked, dojo.js.uncompressed.js).

For release I get about 0.8MB leak for each frame on refresh. I suspect any widgets present on the page add to the leak. Perhaps unload procedure isn't run properly in the frame?

To reproduce - unpack attachment to the root of the dojo source repository (together with dojo.js file). Load test_frames.html. The problem isn't as noticeable with fresh (not built dojo) as it is with baked dojo.

I used Drip (http://outofhanwell.com/ieleak/index.php?title=Main_Page) to monitor memory usage.

Test file to reproduce the problem.

Could this be a case of http://novemberborn.net/javascript/edgvl ?

Actually, I think it could. Thanks. The test case I provided forces IE to jump in memory consumption, but it seems to stabilize after a while. I guess the problem got fixed.

Test file that uses baked dojo.

The problem is still there, especially with baked dojo (which most of the people will use). Download and unpack test2-frames to the trunk check-out folder. It assumes that built dojo is in release/dojo.

could you confirm whether this issue is still the case with trunk?

[ornus]

Yep. It's still an issue. Baked dojo leaks much more than non-baked, but the leak is still there.

why was this moved?

[ornus]

just to let you know this is still an issue.

Pushing to 0.5 since we ran out of time on 0.4.1.

Is it related to ticket #3242?
