As discussed at the Madrid work week, the RTC wakeup is the only way to detect that the connection is alive when the phone is in sleep mode. This patch adds application level ping pong (empty JSON object) with the alarms patch from bug 862322 and PushService-is-a-module from 863598. Wakeup interval is about 5 minutes.

We have a ping message which is "PING" instead of "{}". I like this approach, so we will change our PING message to {}.
But you are not expecting any response from the server, right? (we are sending a "PONG")

@willyaranda: Expecting 'any data', but ideally you'd send '{}' as its half the size and valid JSON :)
of course, if you want to be smart on the server (I don't believe it to be necessary), then if you have messages to be delivered anyway, then you could just not write the pong, but send those messages instead. Basically the client code just wants to receive some data from the server to know that the connection is alive and working.

agree. To optimize the BW and network resources, we should reuse the PING-PONG to send pending messages.
@willyaranda: This is the same I drafted 4 months ago (Issue #122 & PR #137). I'll retake it ;)

I don't think we should do this, for two reasons.
1. We can't do SSL over UDP, so there's no way to authenticate the data we'd receive. We insist that the websocket be over SSL, and I think there's a good reason for that.
2. If we sent data over UDP, we'd have to fit it into a single packet. Spec'ing a minimum network MTU seems pretty undesirable to me; it would place constraints on what network operators could do inside their private networks.

UDP isn't being used. Ping-Pong is only done over Websocket, and only when UDP is not in use.

Probably some misunderstanding :)
Over UDP NO DATA is sent, it's only used to wakeup the device. Here we're talking about Websocket connection where the client network hasn't a WakeUp server so a permanent Websocket connection should be maintained open.
To reach this, we need to PING-PONG (keepalive) every X minutes to avoid intermediate servers closes the connection.

Same as before, UDP is not used to sent ANYTHING. probably a misunderstanding ;)

Now that I understand what you mean, this sounds great.
If I'm understanding the patch correctly, we have to wake up and turn on the radio every five minutes to send a ping? Is that what prior art does? At the very least, we need to do tests to see how this affects battery life. But I think you should get mvines's sign-off as well.

5 minutes is crazy, other PUSH solutions ping each 28 minutes (GCM for example). Adaptative protocol is the best way to find the longest Timeout without lost the connection like APNS.

I think this is a bad API. It means we have to wake up every observer just so

Maybe "reconnectAfterBackoff" would be a better name for this; I was confused

Ah, I see that we used to ping once every minute, but now we ping every 5m.
That's an improvement!
I'd still like to get mvine's opinion on this, though.

shutdownWS calls stopAlarm.
This code is fine, but it sounds like 5m is the wrong thing to do. If you want
to address that in a follow-up, that's fine with me, since this code makes
things better than they were.

Michael,
I'd really appreciate some feedback on a good interval. GCM has a 28min ping interval (i.e. it sends a keep alive packet every 28min), and reconnects if the server doesn't reply.

Comment 16•12 years ago

The less frequent the interval the better, clearly. Drain caused by a quick ~100ms wakeup every 30min-ish seems likely to go unnoticed by the user

Comment 17•12 years ago

This patch is fundamentally flawed for longer push intervals. What it does is set a timer and wait around for a few failed pings. With a long ping interval, this will wait around for multiples of that to pronounce failure.
Working up a new patch with two timers. One timer is the ~30 minute timer that controls 'let's send a ping now'. That should start another timer after sending a ping, a shorter one ~15-20 sec that checks if the server responded within that time, otherwise tries to reconnect.
Patch coming up.

Call me weak, but three is apparently more timers than I can follow. We have
- Retry timer
Delay: Between retryBaseInterval (5s) and maxRetryInterval (20m)
Started in: reconnectAfterBackoff, which is called in onPongTimeout and
_wsOnStop.
When fired: _beginWSSetup
- pingIntervalAlarm
Delay: pingInterval (30m)
Started in: _onPongTimeout if no pong is pending, and after finishing the WS
handshake.
When fired: Send the server an empty message, and wait for a reply (using
setPongTimeoutAlarm).
- pongTimeoutAlarm
Delay: requestTimeout (10s)
Started: After pinging server in _onPingIntervalTimeout.
When fired: Either set ping interval alarm, if we got a pong in time, or
shut down the WS and reconnect after a backoff.
This is confusing to me because all three timers trigger each other, after
varying delays and under various circumstances, and the control flow is
scattered across the code, so you have to have global knowledge to see how
anything works.
Can we try to untangle this spaghetti?
At any given time, we need only one alarm pending, I think. And we should be
in one of a few states:
* connected, waiting to send ping
* connected, waiting for pong
* disconnected, waiting to try reconnecting
* disconnected, currently handshaking
There's no need to send a ping if we've heard from the server in the past 30m,
I think. So every time we receive a message we can reset our alarm to 30m in
the future. That's good for battery life.
Somehow it seems like the maximum reconnect backoff (the 20m) should equal the
ping delay (30m). I don't have a good reason for this, though; it just seems
elegant. So feel free to ignore this. :)
Do you think you could try making this patch more straightforward with all this
in mind?

So this morning we hit a problem where a merge between two changesets that were green produced a changeset where most debug tests leaked. In particular, this merge changeset:
https://hg.mozilla.org/integration/mozilla-inbound/rev/aa2ce091b9fe
I bisected one side of that merge (merging against the tip of the other side), and the guilty changeset ended up being:

Thus I backed it out in:

It is very likely that Bug 863599 combined with this to cause the leaks. AlarmService leaks in the current m-c, which doesn't show up on desktop because AlarmService isn't used. But this bug uses it in PushService which is loaded in deskto pby 863599. There is currently a patch for AlarmService leaks in Bug 867868. If that fixes all the leaks I'll file a new bug and land the fix, after which this bug can be landed again. Bug 863599 can wait a bit.
863599 has been backed out for other reasons.

This is not tef, it should not land on 1.0.1, only on 1.1. At most it would be leo+, but I don't think it's exactly blocking either. So we should just ask for approval-mozilla-b2g18 on the patch.
The rationale for asking for approval/uplift is that push as it's currently on 1.1 it's kinda useless (since once the screen shuts down it stops sending keepalives and thus you lose the 'push' service).
Can you do that, Nikhil?

Patch does not apply correctly on b2g18, this is the patch for b2g18. (I need to test it but I don't have a Wireshark until tomorrow morning)

I figured out how to test it on my home, and remember this:
https://uapush-nv.srv.openwebdevice.com/about
It keeps the "1" opened connection correctly (5 and 10 minutes test, and it does not reproduce bug 869922).
Will update tomorrow with more tests

Oops!
This is a extremely low risk change which affects only Push. It uses an alternative wakeup timer system, there hasn't been any change in the push logic or API. There really aren't any alternatives as bug description states.
