770441 - Thunderbird should not try to save the draft when the user is offline

Status: RESOLVED DUPLICATE of bug 391732

(Thunderbird :: Message Compose Window, defect)

Description

[Mounir Lamouri (:mounir)]

Thunderbird should be able to detect when the user is offline using NetworkManager (this is a Gecko feature). AFAIK, Thunderbird is aware of that because it is trying to get new messages as soon as I'm going online and stop doing so when I'm offline (it might just be an impression though).

This feature should also be used for drafts. It's highly frustrating to write an email offline and be asked every X minutes that saving the draft failed.

Which platform are you using? Mac and Windows already detect online/offline state:

Linux doesn't as there were various issues with detection being inconsistent.

Alternately, if NetworkManager isn't hooking into nsIIOService to tell gecko about online/offline state, then I think that's a bug in NetworkManager.

nsNetworkManagerListener::NotifyNetworkStatusObservers notify observers of NS_NETWORK_LINK_TOPIC. Shouldn't that be enough?

Yes, so this then comes down to the platform you're using. Given that's dbus code, then iirc that's Linux which is disabled due to the previously mentioned detection being inconsistent. AFAIK that's not changed for Firefox, but if Firefox enables it, then I suspect we would.

Hence, I think this is a duplicate of bug 391732.
