Subsequent calls to mozSetMessageHandler will not get properly triggered when the app isn't launched


(Firefox OS Graveyard :: General, defect)

Gonk (Firefox OS)
Not set

When receiving MT SMS, if the SMS app was not previously launched, the SMS is never notified to the user (no notification on top and pull down menu does not show anything either). However, launching the SMS app, a new SMS message is there. Once the SMS app has been launched, any subsequent SMS will be notified.

This seems to only be a 1.3 issue as I can't reproduce on 1.2.

Steps to reproduce:
1) Reboot device
2) Send an SMS to a 1.3 device
3) Verify from logs that the message has been received by the 1.3 device
4) Now launch SMS app and see that there's a new SMS message

Hey Carol,

could you please explain what a "MT SMS" is ? ;-)

Mobile terminated SMS :) Referring to when a device is receiving an SMS (as opposed to a Mobile Originated SMS where the device is issuing the SMS).

> Thanks!

Oki, so this is a normal usual SMS. Thanks!

This looks wrong ;)
Might be related to bug 930604, in that case it would be a gecko problem with not launching an app when we have a system message.

Same regression window than in bug 930604
Summary: MT SMS not notified → SMS received are not notified
Depends on: 932723
We investigated this with Julien and apparently only the first call to mozSetMessageHandler works properly (subsequent handlers will get triggered only if the app is already launched).

This is why:
- the new incoming call works on the dialer even when the app isn't launched
- but not the dial activity

- the new sms reception doesn't works when the sms app isn't open
- but the sms activity does

The dialer calls mozSetMessageHandler for the "telephony-new-call" first, then for the activity, the sms calls mozSetMessageHandler for the activity first, then for the new sms.

Hope this helps, moving to General since this looks system messages related.

Fabrice, are you the good person to continue from here?

That may be a regression from bug 927363. If you can test with this one backed out, great. If not I'll do it but not before next Monday.
We're not supposed to work this Friday so I think next Monday is perfect :)

But that's right that this added line "this.removeMessageListeners(;" could be a good culprit ;)

Just tested that. Indeed, it's a regression of bug 927363. I'm backing out that patch. Please stay tuned.
Close this one as WORKSFORME since bug 927363 which causes regression has been backed out.
