Did Google REALLY Kill Off All XMPP/Jabber Support In Google+ Hangouts? It Still Seems To Partially Work
Did Google really kill off all of their support for XMPP (Jabber) in Google+ Hangouts? Or is it still there in a reduced form? Will they be bringing back more support? What is really going on here?
In my excitement yesterday about Google Voice now being integrated with Google+ Hangouts, I missed a huge negative side of the new Hangouts change that is being widely reported: the removal of support for the XMPP (Jabber) protocol and interoperability with third-party clients.
But yet a few moments ago I did have a chat from an external XMPP client (Apple's "Messages" app) with Randy Resnick who received the message in a Google+ Hangout. I opened up a Google+ window in my browser and I could see the exchange happening there as well. Here's a side-by-side shot of the exchange in both clients:
So what is going on here?
Reports Of Google Removing XMPP
This issue has been widely reported in many of the tech blogs and sites. Matt Landis covered this issue very well in his post: Hangouts Won’t Hangout With Other Messaging Vendors: Google’s New Unified Messaging Drops Open XMPP/Jabber Interop which then generated long threads on Reddit and Slashdot.
The Verge in their lengthy story about Google+ Hangoutscontains this statement from Google's Nikhyl Singhal:
Talk, for example, was built to help enterprise users communicate better, Singhal says. "The notion of creating something that’s social and that’s always available wasn’t the same charter as we set out with when we created Talk." With Hangouts, Singhal says Google had to make the difficult decision to drop the very "open" XMPP standard that it helped pioneer.
The "Google Talk for Developers" pagealso very clearly states this:
Note: We announced a new communications product, Hangouts, in May 2013. Hangouts will replace Google Talk and does not support XMPP.
A Google+ post by Nikhyl Singhal has generated a large amount of comments (not solely about XMPP) and a post from Google's Ben Eidelson about how Google Messenger will be changed by Hangouts has also received many comments.
There was also a Hacker News thread about the news out of Google AppEngine that apps hosted there would not be able to communicate users of the new Hangouts app via XMPP - and providing a couple of workarounds.
A couple of Google+ threads from Matt Mastracci and Jan Wildeboer are also worth reading as is this note from Daniel Pentecost about how he has lost interop with his clients / customers.
But Is XMPP Support Still There?
I was a bit puzzled, though, by a couple of comments from Google's Ben Eidelson down in one of the G+ threads:
+Thomas Heinen Thanks for your report of the issue. Hangouts supports basic interop with XMPP, so you can-for the time being-continue to use 3rd party clients. It does not work the same way as Talk, and so I believe the issue you're having with the XMPP bridge will not resolve in Hangouts.
+Ben Eidelson So there is still some basic XMPP functionality under the hood? Does this mean that Hangouts will still be able to communicate with federated Jabber servers/clients, at least for now?
+Jason Summerfield Not federated support, but supports interop with XMPP clients. Meaning you can continue to use XMPP clients to log in to Google Talk and those messages will interop with folks on Hangouts.
It was this that prompted me to call up Messages on my Mac, where I am logged in via XMPP to my GMail account, and to initiate a chat with Randy as shown above. We found we could chat perfectly fine. We couldn't initiate a callinto a Google+ Hangout from an external XMPP client - although I'll be honest and say I don't know how well that worked in the past. My own usage of external clients has entirely been for chat.
So What Is The Story?
I don't know. The statement quoted in The Verge's story seems pretty definitive that XMPP has been dropped, as does the message sent to AppEngine developers. It does seem so far that:
- "Server-to-server" XMPP, used for federation with other servers / services, has been dropped.
- "Presence" and status messages have been dropped (because the idea seems to be with Hangouts that you just send a message and people will get it either right then or whenever they are next online).
- Within the Hangouts app, you can only connect to people with Google+ accounts, i.e. contacts on external XMPP servers no longer appear.
- Google hasn't made any clear statements on what exactly is going on.
But is this partial XMPP support only temporary? Will it go away at some point whenever Hangouts fully "replaces" GoogleTalk? Or is this a communication mixup? (As happened recently with Google's announcement of DNSSEC support for their Public DNS Service?)
For me the disappointment in all of this is mostly that Google has been one of the largest advocates for the open XMPP protocol and I enjoyed the fact that I could use multiple different chat clients to interact with my GoogleTalk account. I was also very intrigued by the federation that we were starting to see between GTalk and other systems out there via XMPP.
Whereas before Google+ seemed to be an interesting social/messaging backbone to which I could connect many different apps and systems, now Google+ is looking like simply yet another proprietary walled garden - and we don't need more of those!
Hopefully we'll hear something more out of Google soon.
P.S. Here's another interesting viewpoint: Google Hangouts and XMPP – is cloud harming the Internet?
UPDATE: In a comment over on Google+, Daniel Pentecost states that Randy and I were not actually using Hangouts:
Dan, you weren't actually chatting through Hangouts. You were chatting through Google Talk which itself has a bridge into Hangouts. It only works b/c Randy is a Gmail user and still has access to Google Talk in Gmail.
Perhaps that is the case, which again then begs the question of whether this is only a temporary capability until GoogleTalk is shut down.
