Later, we can fork off a separate process to do that task, but for
now, we can just rely on the fact that unless the server was just
rebooted, the relevant messages will already be in that cache, and
even if it was, getting the needed messages once each is not a
particularly expensive query.

It can easily cost an entire line, and the information is available by
clicking on the sender's name. Plus on a phone, you can't hover
anyways.
Annoyingly, this tends to put the popover partly off the window, but
there must be a way to fix that separately.

It's possible for selected_message_id to not exist in zhome. For
instance, when you open the page to a narrowed URL, there is a race
between loading the narrowed messages and loading all your
messages. If the narrowed message request completes first, it will
update selected_message_id to your initial_pointer if the latter
happens to be among the narrowed messages. Even if it is not, you can
select a message by clicking on it before the zhome request finishes.
Then the old code would never add that selected_message_id to the
zhome table, so it wouldn't show up in the Home view or if you
re-narrowed.
I'm pretty sure there are still cases where the selected_message_id
might be outside the range of messages in zhome, in which case adding
to zhome might put old messages at the bottom. I observed this twice
on staging but was unable to reproduce it consistently.

The schema change made this no longer a guarantee, and creating duplicate
PUs is not harmful.

This involved splitting off into a separate function the second step of

This allows us to handle the return_messages_immediately part of
get_updates requests without having to talk to the database.

This commit has the effect of eliminating all of the non-UserActivity
database queries from the Tornado process -- at least in the uncached
case.
This is safe to do, if a bit fragile, since our Tornado code only
accesses these objects (as opposed to their IDs) in a few places that
are all fine with old data, and I don't expect us to add any new ones
soon:
* UserActivity logging, which I plan to move out of Tornado entirely
* Checking whether we're authenticated in our decorators (which could
be simplified -- the actual security check is just whether the
Django session object has a particular field)
* Checking the user realm for whether we should sync to the client
notices about their Zephyr mirror being up to date, which is quite
static and I think we can move out of this code path.
But implementation constraints around mapping the user_ids to
user_profile_ids mean that it makes sense to get the actual objects
for now.
This code is not what I want to do long-term. I expect we'll be able
to clean up the dual User/UserProfile nonsense once we integrate the
upcoming Django 1.5 release, with its support for pluggable User
models, and after that I change, I expect it'll be fairly easy to make
the Tornado code only work with the user ID, not the actual objects.

We suspect that these seem to be causing a regression where scrolling
in narrowed views gets really sluggish, but we haven't totally been
able to figure out why since it's challenging to reproduce locally.
(It currently manifests itself on staging but not prod.)
So for now we'll back them out. Here's the full set of things:
Revert "Cause update_floating_recipient_bar to get called less frequently."
This reverts commit a6c1518c4001a2dde44d7b512236795da3ccd351.
Revert "Remove double-scroll in un-narrowing code."
This reverts commit 3dde6c27ffa1e8afa1a084b1b2baee3bc0512962.
Revert "Reset our scroll position if we change our hash to "#"."
This reverts commit 925b44d770c96dafaabebc9e0114f9a3b8f53c4d.
Revert "Properly update floating subject bar when you are at top of page."
This reverts commit 6633cc8a81aedcbb31b30d7c1f27816f8808c700.

Note that on local dev servers, this will print out every half second, as
Tornado polls for file changes for autoreloading. In production it will only
print out when network events occur.

This should remove a database query invoked from Tornado by our
decorators in the common case.
We use hashlib.sha1() on the key because memcached doesn't support
keys with whitespace in them.

Previously it wouldn't work due to using the wrong port numbers.
This commit also has the side effect of fixing the fact that our
frontend tests would send real emails and log events to the real
message log.

This should save a database query when we later need to access fields
such as the user's realm name in format_updates_response.

This code is from a previous protocol where the users array was posted
as a comma-separate list, rather than encoded via json.

This is for consistency with the rest of our code dealing with message
delivery, which always uses the user_profile_id.

Putting update_floating_recipient_bar in the old location caused it to
be called on every single keypress, which is unnecessarily
expensive. Instead, just call it once when we think we might actually
need it: after initiating a narrow.
