LJ's Jabber Service loses messages sent to an off-line subscriber

Jul 15, 2008 14:14

I've always suspected that, but yesterday it made me sick completely and I decided to check it with testing: my friend was sending me messages while I was logged out. All of them were lost as it turned out when I logged in.

LiveJournal does not have its Jabber server configured to retain messages sent to offline users. However, you should get an error message back saying that the message could not be delivered rather than the message just being silently dropped. Are you not recieving the error?

LJ Talk runs on DJabberd, which does have a plugin that implements retention of messages sent to users while they're offline. The module is called DJabberd::Delivery::OfflineStorage, but obviously it's up to the LiveJournal folks to enable this if they want to support it.

Yeah, that's the problem. It's being silently dropped.

Client issue.

I just tested it using LJ Talk, and a personal machine running djabberd, running Adium 1.3.1 on OS X. Sending to an offline user gives me a message that the subscriber is offline, and offers me the option to have the client cache it until they come on next, or to send anyway.

Hm, what would be if you had used Adium connected directly to LJ's jabber service, not own djabberd?

As I said -- tried it with both LJ talk and my own, same result.

Well, it was ambiguous, actually.

> same result.

I see. Thanks.

Wow, you're argumentative, if it's not useful info, either clarify what you need or let the conversation end at that point. If you want someone to be helpful, be nice, and stop discouraging people from giving information freely by being snarly.

> if it's not useful info poige September 17 2008, 14:06:00 UTC

Who said that? It was quite useful, so I said "thanks".

I think you've messed up something.
