STR: - Create a new add-on with the following main.js (and nothing else): require("widget"); - cfx xpi - Install xpi in a fresh profile - Disable add-on again - Go about:memory?verbose - Minimize memory usage - Wait a couple of minutes, just to be sure - Minimize memory usage -> Observe that all the jetpack compartments are still present Tested and affected SDK versions: 1.3, 1.4.2 Tested with the latest Win64 Nightly

Just to make sure that it is not just a broken Nightly: Same issue can be observed under Firefox 10 Win32/Oneric x86_64 (The compartments are unnamed, except for the bootstrap.js compartment, due to lack of auto sandboxName support)

Actually, it now seems more likely that the culprit might be in addon-kit/windows. addon-kit/windows and addon-kit/tabs leak as well, but addon-kit/widget and addon-kit/tabs require addon-kit/windows.

I've tested that against reddit-panel example, and it doesn't leak anymore. More comments in the pull request.

Irakli, I pushed a new changeset, with a simplier fix.

Commit pushed to master at https://github.com/mozilla/addon-sdk https://github.com/mozilla/addon-sdk/commit/6a867fb0dab42b165d133095f4133688db5b08fd Merge pull request #344 from ochameau/fix-widget-leaks fix Bug 724404 - require("widget") creates zombie compartments r=@gozala

Looks good. Can't reproduce this issue anymore with the referenced fix included. All compartments for widget modules are gone.

What version of the SDK should I build against to avoid this bug? Thanks!
