1052720 - Homescreen doesn't come up and not able to start any apps

Status: RESOLVED WORKSFORME

(Core :: DOM: Content Processes, defect)

Description

[Anshul]

Attachment: homescreen not starting

[Blocking Requested - why for this release]:

With the recent build I am noticing that the homescreen app doesn't start at all. On clicking the home button once after the boot, the homescreen app starts. However unable to open any apps. Clicking on an app icon shows the black ground with the app icon in the center and the screen stays like that.

In the logs I see an error Content JS ERROR at app://verticalhome.gaiamobile.org/gaia_build_defer_index.js:400 in GridItem.prototype.doRenderIcon/<: Error fetching icon [Exception... "File error: Not found"  nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)"  location: "JS frame :: app://verticalhome.gaiamobile.org/gaia_build_defer_index.js :: fetchBlob/< :: line 381"  data: no] 

Not sure if this related but thought I will mention.

This is 100% reproducible and on current trunk?
Kevin, any ideas?

This bug could not be reproduced on the latest Central Flame, B2g-inbound flame, or Mozilla-inbound flame builds.

According to comment 3 it does not reproduce. I'm going to try to test this again.

Comment 5

[Anshul]

I am still seeing the issue with the latest code from Moz central. Please try on the KK based flame devices.

QA wanted for No-jun to try.  he has a mozilla-central build running on KK flame.   No-jun, please report your investigation here.  thanks.

Comment 7

[No-Jun Park [:njpark]]

I could not reproduce this on both 289mb and 319mb flame-kk setup on master (2.1) branch.  The phone starts up to the lockscreen, and when lockscreen is unlocked, homescreen shows up.  When lockscreen is disabled, it starts to the homescreen directly.

I ran ./config.sh flame-kk and did build for gecko and gaia.

Mike, could you try to reproduce it? Thx.

Verify with Flame-KK + v2.1 and cannot reproduce this issue

This might be a dupe of bug 1051633.

Does seem like it. Let me try the patch in the bug 1051633 and see if that solves the problem for us.

Comment 12

[Anshul]

The patch in bug 1051633 doesn't seem to fix the issue for me.

Comment 13

[Inder]

:bajaj -- can Moz please fix this with priority. We are not able to start anything on 2.1 without this fixed.

I'll ask some one from Homescreen team to look at it and inspect the shared logs, but given we are unable to reproduce it on Flame we will need more help here.

Can you guys give Flame+2.1 a shot and see if you hit this?

Comment 15

[Kyle Huey (Exited; not receiving bugmail, old account, do not use)]

I still think this is related to bug 1051633.

Comment 16

[Inder]

:bajaj -- this is reproducible, see comment 10.

Comment 17

[bhavana bajaj [:bajaj]]

:gwagner, apparently this happens for every launch CAF is trying to make, unlike our discussion which was, this may happen in ~2days after continuously seeing the device.

Comment 18

[Inder]

Anshul -- can you please try this patch and see if it helps: https://bugzilla.mozilla.org/show_bug.cgi?id=1051633#c21

Comment 19

[Kyle Huey (Exited; not receiving bugmail, old account, do not use)]

FWIW I suspect this is triggered by using DMD.  If you turn that off it will probably go away.

The debug patch listed above doesn't fix the issue.

Comment 21

[Kevin Grandon :kgrandon]

Inder, Anshul - Please see comment 19. Can you confirm if these devices running DMD? If they are can we try disabling it and reproducing the issue?

Comment 22

[Michael Vines [:m1] [:evilmachines]]

Yes, we had DMD enabled and have disabled it for now to get unstuck.  Thanks for the hint.

Comment 23

[Gregor Wagner [:gwagner]]

Assigning to Cervantes since the work in 1051633 should fix this.

Comment 24

[Tapas[:tkundu on #b2g/gaia/memshrink/gfx] (always NI me)]

We are not seeing this issue after re-enabling DMD on my local build without applying any fix from bug 1051633 with following gaia/gecko:

https://git.quicinc.com/?p=b2g/mozilla/gecko.git;a=tag;h=refs/tags/AU_LINUX_GECKO_B2G_KK_2.0.01.04.00.114.085

https://git.quicinc.com/?p=b2g/mozilla/gaia.git;a=tag;h=refs/tags/AU_LINUX_GECKO_B2G_KK_2.0.01.04.00.114.085

It may be some other fix which has landed and solve this issue for us !. 

This bug can be closed if Cervantes is OK with this ! Thanks
