911345 - [Browser] Content loads in zoomed out state

Status: RESOLVED WORKSFORME

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

Description

[Tony Chung [:tchung]]

Attachment: b2g_browserShrinkContent.png

Certain conditions will cause the website to load its mobile content into a zoomed out version of the site.    See screenshot.   This is reproducible if you are mixing in cache clearing, force killing app, and launching site for the first time.

BTW, this example is amazon.com, which is loading mobile content, not desktop.

Ben, if this is a gfx/layout bug, please kick it over to them.

Screenshot attached.

Repro:
1) install 1.2 nightly build on Buri
** BuildID 201308300040204
2) launch browser app > settings
3) clear browsing history, and clear cookies/cache
4) force kill Browser app process for clean start
5) relaunch Browser App, and visit URL (ie. www.amazon.com)
6) If this doesnt work, try another trick:

6a) launch 2nd tab, and go to cnn.com.  let page load
6b) switch tabs back to 1st tab.   

7) Verify you hit the shrinked content page

Expected:
- mobile site loads full size

I can reproduce this with the above STR, but only sporadically (perhaps 1 out of every 5 tries). It would be nice to have a more reliable way to reproduce this.

i agree, my reproduction was like 20-40% of my tries.  will continue to work on STRs, but it was annoying enough that i believe this regressed and needs attention for 1.2.   in your 20% reproduction, is there enough data that you can work with?

also, if i can provide any useful logging let me know how.  when i repro'd it, i didnt see anything in logcat that would have been beneficial.

I no longer see this with my patch for bug 904533. Of course, given the low repro rate, it's hard to tell whether the problem is really gone or it just didn't happen for me.

[Botond Ballo [:botond]]

Actually, I can still see this occasionally, so I guess bug 904533 didn't fix it :(

One thing I found that reproduces this a bit more often, is at step 6a of the STR to Google "cnn" instead of going to cnn.com. When I do that, the Google search page sometimes loads zoomed out.

need more reliable STR for this to remain a blocker

Note - I was able to see this when I was testing loading up bugzilla.mozilla.org. Try navigating around bugzilla.mozilla.org on your phone - you should see this bug happen.

I was able to reproduce this issue 4/5 times based on the description of the bug (steps 1-5) I was able to see the shrinked content page of the following pages
1. www.target.com
2. www.firefox.com
3. www.Amazon.com

While investing this issue, I was also able to see that the issue stopped occuring after the 30th build. 
It does not reprodece on today's build.
