Description

[Barry Marshall]

Attachment: Software Update window created is blank

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150122030202

Steps to reproduce:

1)  Download Minefield
2)  Enable e10s
3)  Wait for Nightly Update to happen in background and create window
4)  Examine window contents


Actual results:

A blank window with an "Update Now" button is created


Expected results:

Chrome should have loaded Update Available window contents along with other graphics

[Jim Mathies [:jimm]]

Barry, is there any chance your machine went to sleep while you were waiting? I'm thinking this might be bug 691193.

Comment 3

[Barry Marshall]

While I do use Windows Sleep a lot, this wasn't the case for this screenshot.

When I run Nightly, my usage pattern means that I can often end up in the case where I'll have 2 updates available to me.  The laptop was put to sleep through the weekend without accepting the first update offer, but then after wakeup I accept the (now stale) offer, which completes successfully and the code restarts.  The screenshot was from the second offer that happened in the background soon afterwards.

If I do a manual "About Nightly" check, the window that gets created with focus renders the normal window contents correctly that I expect.

The example shown in bug 691193 also shows a totally blank window interior, whereas this example still provides the "Restart Nightly" pushbutton in the corner.

It might not be e10s causing this, but that's the only change that I've had recently to this system setup.

[Brad Lassey [:blassey] (use needinfo?)]

Juan, need some solid STR here

Comment 5

[juan becerra [:juanb]]

Barry, could you copy paste the app.update.* preferences in your profile? Go to about:config and look for app.update and take a screenshot.

After toggling a few settings I was able to get the Software Update dialog to come up, but I have not been able to get it to come up blank yet.

Could you also attach the information that shows up when you go to about:support?

Attachment: about:config screenshot

Comment 7

[Barry Marshall]

Screenshot attached for about:config.

The problem seemed to happen with builds before 20150122030202.  The latest background update offer I had did give me a proper dialog box filled in with content, but I don't think it was present through a Sleep cycle?

Does the Offer Dialog box pull the contents from an Internet site or is it cached by Update Services?  Maybe the resources were changed and/or taken down and the info got stale and wasn't available?

about:support for the currently installed 20150129030202 CSet: 6bfc0e1c4b29 code is:

Comment 8

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

Attachment: Reproduced without e10s

I can reproduce this without e10s enabled.

Comment 9

[Barry Marshall]

Oh well.  So much for my e10s theory.  :-)

So do you get it a Sleep-based issue, a content issue, or something else?

Comment 10

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

So I should point out that I was able to get this with e10s disabled, that I get it _far more frequently_ with e10s enabled. Like, I'm almost guaranteed to get this with e10s enabled.

I just got it again this morning.

Re-nomming.

Comment 11

[Jim Mathies [:jimm]]

Barry, do you still see this in Nightly?

Comment 12

[Barry Marshall]

(In reply to Jim Mathies [:jimm] from comment #11)
> Barry, do you still see this in Nightly?

The update I've got today appeared correctly, e10s is enabled.  I've got an additional pending update and some Suspend actions I know I've got coming up, so let me see how we get on today.

Comment 13

[Barry Marshall]

Still haven't recreated lately...  keeping an eye out...

Comment 14

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

My STR (running Windows 7 64-bit).

1) Download Nightly, and start it up. Make sure updates can be applied automatically.
2) Make sure Windows is set to go to the lock screen after a timeout.
3) Focus some other application, like Thunderbird.
4) Wait for your machine to enter the lock screen (or just do it yourself, that's probably fine too).
5) Wait for an update to be applied in the background. This usually happens when I'm at home, since my Windows machine is in the office.
6) After you're sure an update has been applied (perhaps wait until around 10AM ET the next day?), unlock your machine
7) Nightly should have opened the popup to alert you that Nightly needs restarting to update - but it's not focused. Click on the Nightly icon in the dock and choose the popup window to bring to focus.

ER:

The popup should have been painted with buttons and text.

AR:

The popup is mostly blank.

Comment 15

[Barry Marshall]

Confirmed still appearing as per Mike's test case.  I just got it this morning again, probably in the method as he describes.  The machine had been manually pushed into a Locked state by me and put into Suspend mode.

Comment 16

[Mike Conley (:mconley) (:⚙️) (PTO June 8 - 12)]

I have a second, easier method for reproducing this, which reproduces reliably on release with e10s disabled - so I'm now reversing my stance from comment 10. I'm reasonably certain this is not e10s related.

STR:

1) Open the Browser Console (Ctrl-Shift / Cmd-Shift J), and put this in:

setTimeout(() => {Services.ww.openWindow(null, "chrome://mozapps/content/update/updates.xul", "", "chrome,centerscreen,dialog=no,resizable=no,titlebar,toolbar=no", null)}, 10000)

And press enter.

2) Within 10 seconds, lock the desktop by going to the Start button, and choosing Lock (for me, I need to click into the menu to the right of the Shut Down button to find Lock. I suspect it will be different depending on the user settings / permissions).

3) Once the desktop is locked, wait until 10 seconds has elapsed.

4) Unlock the desktop

ER:

The update dialog should be displayed and painted.

AR:

The update dialog is opened, but not painted. It is fully blank as per the screenshot.

Comment 17

[Gabriel]

Yes, can be reproduced with the method from comment 16.

Comment 20

[Gabriel]

This bug is still present in Firefox 45.0b2

Comment 21

[Gabriel]

Tested on Firefox Quantum 65.0b5 (beta channel), on Win7 x64 and Win10 x64, and can't reproduce because of some changes or error.

When pasting in console:
> Services.ww.openWindow(null, "chrome://mozapps/content/update/updates.xul", "","chrome,centerscreen,dialog=no,resizable=no,titlebar,toolbar=no", null)
the following error is prompted:

So, because "Services" is changed/removed, can't test it.

I have managed to test it, Firefox Quantum 65.0b5 (beta channel), on Win7 x64 and Win10 x64.
On Win7, the windows is blank (white), in Win10 the window is drawn (progress bar, "Applying update..." text and "Hide" button).

I have tested it from an "about:about" window (very important), opened the console and run:
> setTimeout(() => {window.open("chrome://mozapps/content/update/updates.xul","","chrome,centerscreen,dialog=no,resizable=no,titlebar,toolbar=no")}, 10000)

After more than 10 seconds, the window was present, in Win10 was drawn with elements but in Win7 was blank (white).
