With screen locked, notifications sometimes don't show up, only sound

[Omer Akram]

There might be other scenarios to reproduce this issue but one that I found is out of a few times, when the screen is locked, gmail notifications don't show up at all, only the blip sound happens on polld refresh.

1. Make sure notifications are being received
2. Lock the screen and create an incoming gmail notify

Out of the few attempts the notifications will stop showing unless the ubuntu-push-client is restarted.

note, I do not see the new gmail messages in the indicator either, so not only did the phone not turn on but the messages were not added to the indicator. However something caused the phone to beep and blink

[Jonas G. Drange (jonas-drange)]

Proposed reproduce:
1) clear the indicators
2) send some messages to your gmail account
3) the phone properly wakes up and displays the messages on screen and in indcator
4) put phone back to sleep and send more messages to gmail
5) now the phone will just beep but not turn on the screen or add messages to indicator

I can reproduce reliably in this way:
 1) clear the indicators
2) send some messages to your gmail account
3) the phone properly wakes up and displays the messages on screen and in indcator
4) put phone back to sleep and send more messages to gmail
5) now the phone will just beep but not turn on the screen or add messages to indicator

it stays broken until you clear the indicators

=== UX Comment ===

As per the design specification for the new notification system: (http://bit.ly/1P70Dkb)

- In general, applications can fire only one notification at a time, but multiple applications can fire their notification simultaneously. All notifications should be treated as if they are in a queue and will be handled sequentially according to their fire time (in a FIFO manner).

- Grouping notifications from the same app in the notification centre and lock screen:

*If a notification of a certain type is already pending in the queue (not fired yet) when an app tries to send a new notification, they will be combined into a summary notification for that app.
*When the phone is locked, if a summary notification is already displayed on the lock screen and when a new notification from the same app arrives, the number displayed on the secondary icon will change to the correct count (detail text will change accordingly).
*Therefore, the notification bubble should be discarded from the queue and never displayed as a single bubble in normal usage. Same behaviour applies to the notification centre.

======

@jonas-drange, you mentioned that when you get 4 gmail notifications without clearing any, the 3rd and 4th notification will only emit a beep. So I understand that this bug is not only related with the screen being locked but also with the number of notifications that are in the queue?

My suggestion is that the grouping of notifications should not be dependant on the number of them but rather on the conditions listed above, otherwise, each notification should be displayed individually.

I'm happy to discuss this further.

  * Force parsing of email address even if it violates RFC 5322. Encode
    icon file paths since unity-notifications require it. Summarize
    notification bubbles when > 10 in a batch, but never summarize in
    the indicator. (LP: #1429276)
