876823 - Gallery screen goes blank during BT file transfer

Status: RESOLVED FIXED

Description

[Greg Grisco]

1. from Settings/Bluetooth, pair device with another BT device
2. from Gallery, attempt to transfer photo via bluetooth to device paired in step 1.

At this point, do not accept the BT transfer on the receiving end

3. from Gallery, select another photo and attempt to transfer photo via bluetooth to same paired device.

Results: The screen goes blank on the sending device and remains that way until original transfer is accepted on the receiving side.

Casey, does this one perhaps just need an existing transfer progress bar? Hoping for the easy answer here, but defer to your good experience and judgment.

Hi Greg - Out of about 5 attempts, I had the blank screen once. Typically it just closed the bluetooth dialog and return to the previous view, which is good.

However, there was one thing missing. On the page 12 of the current transfer patterns doc, (https://mozilla.box.com/s/3br18ke7tj0x1s5vj5tv), when the user initiates the transfer, a banner is displayed with an upload icon, the file name and the string, "Upload started". This signals to the user that the transfer has been initiated.

Should this be filed as a separate bug?

Are you saying that correct behavior is to not allow the second transfer due to first one being in-progress?  If that's the case, I think the user needs to have some feedback.

To me it sounds like it should be filed as a separate bug.

I'm terribly sorry, Greg, but I misunderstood the original bug so please disregard comment 3. This is a valid error and needs to be fixed. The expected behaviour is that the second item should be queued until the first file is either accepted or rejected. Once the initial transfer is complete (whether it succeeds or fails), the second transfer prompt is displayed.

Have I answered the question this time? If not, please flag me. And sorry for the confusion!

Receiving the below error state when issuing transfer request. 

I/Gonk    (  108): dbus_func_args_timeout_valist: D-Bus error in GetServiceAttributeValue: org.bluez.Error.Failed (GetServiceAttribute Failed)

Occurs in latest pvt build.  Also tried earlier build from 2013-06-01-07-02-10 and getting same result.

Pulling in Eric Chou and Gina Yeh for assistance.

I can reproduce this easily. 

This is a regression of bug 860166. Currently Gecko Bluetooth would not fire DOM Request onerror event even when the connecting process fails. I'll handle this.

This may also happen in v1.0.1, not sure if we can still uplift, though.

Agree with Eric. This should be a regression of bug 860166 and we need a patch for v1.0.1.

Shall we also check sInShutdown here?
