Description:
test_browser_bookmark.py is failing on multiple tracebacks today on Jenkins servers. When attempting to perform this test on local machines, the test does not timeout on occasion, making it difficult to pull consistent failures. Seems like it may be related to a memory issue on returning to homescreen (bug 1166449), as icons are not drawn on returning and there is a large delay in setting up the homescreen after attempting to add a bookmark. Scrolling down after the test "added" a bookmark revealed that no new bookmark is present.

Repro Steps:
1) Update a Flame to 20150629134017
2) Open the Browser app
3) Open webpage: 	self.test_url = self.marionette.absolute_url('mozilla.html')
4) Add to homescreen and change name
5) Return to homescreen

Actual:
Homescreen is revealed and test times out

Expected:
Bookmark is added to homescreen, renamed and deleted

Issue DOES NOT REPRODUCE manually

Ok, I can see this too and it happens manually for me once too. In that case, the "Edit bookmark" dialog just disappeared while typing in the input.

This is a logcat of when this issue happens.

I guess that makes this a regression from bug 1144132, since an Activity window is involved here (which is lmk-ed) and bug 1178226 is a similar bug which was also caused by bug 1144132.

Gabriele, can  you take a look at this?

	Comment 5 • 9 years ago

I started looking into this but I'm not sure how to reproduce this manually, which URL am I supposed to use for step 3 in comment 0? Not clearing my NI until I can reproduce this myself.

1) You have to use the latest engineering build on the Flame, using 319MB internally.
2) Open the Browser app
3) Open webpage, any webpage will do, e.g. http://google.com (but a more memory intensive site will increase the likelyhood, I think. It happened a lot with me, using http://nu.nl )
4) Add to homescreen and change name

Result:
- While trying to change the name, the "Add to Home" activity will suddenly disappear.

OK, I've managed to understand why this is happening. For some reason the browser app is not being marked as an activity opener, this causes the priority of it to drop far enough that it's getting killed by the LMK. I'm now trying to figure out why the normal mechanism used to mark activities is failing.

Filed bug 1182457 to track the root cause of this issue.

We now have browser pinning and a test for that will be written in bug 1217404.
