We also now separate out the times for the socket overhead, the

(imported from commit e1683f7f28b968b86ebb701b0ac29b00ac6d67c3)
One quirk here is that the Request object is built in the
message_sender worker, not Tornado. This means that the request time
only counts time taken for the actual sending and does not account
for socket overhead. For this reason, I've left the fake logging in
for now so we can compare the two times.

Clients can only have one connection at a time, anyway, so we can
just keep track of a client id, instead. This makes reconnections
easier.
It's a little funny to use queue ids for the client id, but we know
they should exist by the time the client is connecting and they are
guaranteed to already be unique and authenticatable. We will also
eventually be integrating the event system and the socket code closer
anyway.

The register_json_consumer() function now expects its callback
function to accept a single argument, which is the payload, as
none of the callbacks cared about channel, method, and properties.
This change breaks down as follows:
* A couple test stubs and subclasses were simplified.
* All the consume() and consume_wrapper() functions in
queue_processors.py were simplified.
* Two callbacks via runtornado.py were simplified. One
of the callbacks was socket.respond_send_message, which
had an additional caller, i.e. not register_json_consumer()
calling back to it, and the caller was simplified not
to pass None for the three removed arguments.

Here we introduce a new Django app, zilencer. The intent is to not have
this app enabled on LOCALSERVER instances, and for it to grow to include
all the functionality we want to have in our central server that isn't
relevant for local deployments.
Currently we have to modify functions in zerver/* to match; in the
future, it would be cool to have the relevant shared code broken out
into a separate library.
This commit inclues both the migration to create the models as well as a
data migration that (for non-LOCALSERVER) creates a single default
Deployment for zulip.com.
To apply this migration to your system, run:

This is implemented by bouncing uploaded file links through a view
that checks authentication and redirects to an expiring S3 URL.
This makes file uploads return a domain-relative URI. The client converts
this to an absolute URI when it's in the composebox, then back to relative
when it's submitted to the server.
We need the relative URI because the same message may be viewed across
{staging,www,zephyr}.zulip.com, which have different cookies.

The gather_subscriptions_helper() does a separate query to
get emails from user_ids, and it returns an email_dict to its
caller.
This may seem like a step backward, since gather_subscriptions()
now needs to do an additional query, but there is some benefit
in passing fewer redundant emails over the wire from the DB.
The real payoff, though, will come in subsequent commits, where
we will reduce the amount of data going over the wire to the browser,
which will benefit users with slow connections.

Steve Howell: In both trials, we set it up so that only 382 of 9382 rows need to be updated. The first trial runs about 63x as fast. The second trial, if my theory is correct, is doing 24x as many writes as it needs. Both trials are reading all 9382 rows.
Steve Howell: The expense of the update statement seems to be proportional to the number of rows you "update", not the number of rows that you actually change.

When we send a message, we send some presence information to Tornado
to help it figure out how to generate emails for idle recipients of
a message. This change limits the presence info to being the
intersection of present users and recipients of the message. It is
just an internal optimization to avoid queueing up unneeded data.
The history behind this feature is that I implemented it a while
back, but I think I made a rebase mistake that sent all the presence
data over the wire, despite having code to filter on recipients.
It was mostly harmless, just leading to some inefficiency which is
now fixed.

If you expand subscribers on your settings page, you will now see
a query like this in your postgres logs:
SELECT "zerver_userprofile"."email"
FROM "zerver_subscription" INNER JOIN "zerver_recipient" ON ("zerver_subscription"."recipient_id" = "zerver_recipient"."id") INNER JOIN "zerver_userprofile" ON ("zerver_subscription"."user_profile_id" = "zerver_userprofile"."id") WHERE ("zerver_recipient"."type" = 2 AND "zerver_subscription"."active" = true AND "zerver_recipient"."type_id" = 40 AND "zerver_userprofile"."is_active" = true )

get_subscribers_backend() now calls the new get_subscriber_emails()
function, which just queries the email field:
"zerver_userprofile"."email"
...instead of querying about 40 fields that it never uses.
I was able to verify the query slimming by watching my postgres server log.
Also, you can verify that the ORM does roughly 16x less work using values():
>>> def f(): return [sub.user_profile.email for sub in list(Subscription.objects.all().select_related())]
...
>>> def g(): return [row['user_profile__email'] for row in list(Subscription.objects.all().values('user_profile__email'))]

>>> def timeit(func): t = time.time(); func(); return time.time() - t

These engagement data will be useful both for making pretty graphs of
how addicted our users are as well as for allowing us to check whether
a new deployment is actually using the product or not.
This measures "number of minutes during which each user had checked
the app within the previous 15 minutes". It should correctly not
count server-initiated reloads.
It's possible that we should use something less aggressive than
mousemove; I'm a little torn on that because you really can check the
app for new messages without doing anything active.
This is somewhat tested but there are a few outstanding issues:
* Mobile apps don't report these data. It should be as easy as having
them send in update_active_status queries with new_user_input=true.
* The semantics of this should be better documented (e.g. the
management script should print out the spec above)x.
