835829 - Membuster testcase causes the browser to have two setVisible(true)'ed tabs

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: Gaia::Browser, defect)

Description

[Justin Lebar (not reading bugmail)]

STR:
 * Reboot the phone
 * Open the browser app
 * Visit http://people.mozilla.com/~cjones/membuster.html
 * Wait 20s or so for all of the pages to load.
 * $ adb shell b2g-ps --oom

Actual results:

I see something like

> APPLICATION       OOM_ADJ 
> b2g                  0     
> Cost Control         1     
> Browser              1     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              6     
> Browser              1     

Note that two browser processes have OOM_ADJ == 1.  That means they're both in the foreground.

Expected results:

Only one Browser process should be in the foreground.

FWIW, I'm seeing this with a patched Gecko/Gaia build.  I don't believe my patches are causing this problem, but we need to test with a clean build.  Sorry I don't have time to context switch back to a clean build to verify this right now.

I don't think this actually blocks anything; I can handle two foreground tabs.  10, not so much (bug 836647).

I think this was fixed by bug 834059, Justin please reopen if you think otherwise.
