Empirically, we only get these for malformed emails where the charset
specified in a message part header does not match the true encoding of
the part. I checked what the resulting Zulip looked like for the
original offender, and it looked find with ignoring errors.

We now bulk-fetch subscription information once from the database
and use it throughout bulk_add_subscriptions in order to avoid
hitting the db O(streams) times.
On my machine this shaved the accounts_register API call from making
66 queries to making 37 queries.

We have a handy bulk_add_subscriptions function to make cases
like this fast, so lets use it.
On my machine this reduces the number of db queries during account_register
from 112 to 66.

It shows domains and how many active users they have. A
user is consider active if they have done something at least
as active as updating their pointer in the last day. Domains
with no meaningful activity in the last two weeks are excluded
from the report.

A small functional change here was to eliminate an enormous "Usage"
headline that was already implicit from the tabs. It would have
complicated the refactoring to try to preserve it, and I don't think
anyone will miss it.
Extracting this template will give us a little more flexibility
to customize future tabs in the /activity page.

We are still showing the same data points, but the logic to drill
down on details for a particular realm is now all server side,
not client side, and we are smarter about omitting fields. In
summary mode, we don't show empty Name or Email columns. In
detailed mode, we show the realm as a headline instead of a column.
In this version you do lose the ability to see all system users in
the same view, but Waseem is ok with this.

Before, it was trying to use connection.queries, but Django

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.

When you load the activity report, it will just show summary
counts for realms, but if you click on a realm, you will see
details about users in the realms. You can also click "Show all"
to see an interleaved view of realms and users.

The overall message charset may be null or not match the part's
charset. Even though it's unclear from the documentation,
experimentally using the charset for a message part seems to give you
the charset even for non-multipart emails.

For a 4-person stream, we were hitting the DB 8 times, and 4 of
those queries were to lazily get user.email for the 4 recipients
due to upstream code using only(). I added user_profile__email
to the only() call.
I believe this regression started 9/18, and after pushing this
to prod, we would should look at this graph:

Use stream.num_subscribers() in check_if_a_bot_is_sending_a_message_to_an_empty_stream().

Warn inside these functions when you get data on streams that you
are not subscribed to:
add_subscriber
remove_subscriber
user_is_subscribed
The back end should be smart enough not to spam us with subscriber
info that we don't care about.

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 )
The join's still complicated, but the list of fields is one instead of 40+.
(imported from commit 48de1f888193a4d23fcea52d0b633d134e4a3ff7)
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
...
>>> timeit(f)
0.045198917388916016
>>> timeit(g)
0.002752065658569336

LinkPattern returned a string which contained a placeholder if the URL was

m.group(0) is always incorrect because python-markdown modifies your regex
