Sundar Guntnur 5aefb5e656 webhook: Catch potential JsonableError when parsing widget_content.
The `widget_content` key is expected to contain a string which parses
as JSON; in the event that it does not, log the error and notify the
bot owner, instead of failing silently.

Fixes #16850.

m-e-l-u-h-a-n aea31eb31f api: Add REALM_DEACTIVATED error code.
In `validate_account_and_subdomain` we check
if user's realm is not deactivated. In case
of failure of this check, we raise our standard
JsonableError. While this works well in most
cases but it creates difficulties in handling
of users with deactivated realms for non-browser
clients.

So we register a new REALM_DEACTIVATED error
code so that clients can distinguish if error
is because of deactivated account. Following
these changes `validate_account_and_subdomain`
raises RealmDeactivatedError if user's realm
is deactivated.

This error is also documented in
`/api/rest-error-handling`.

Testing: I have mostly relied on automated
backend tests to test this.

Fixes #17763.

Sumanth V Rao e12f682e2e markdown: Include text & url in `topic_links` parameter of our API.
The linkifier code now includes both the shortened text and the expanded
URL, sorted by the order of the occurrence in a topic. This list is passed
back in the `topic_links` parameter of the /messages and the /events APIs.

topic_links earlier vs now:

earlier: ['https://www.google.com', 'https://github.com/zulip/zulip/32']

now: [{'url': 'https://www.google.com', 'text': 'https://www.google/com},
      {'url': 'https://github.com/zulip/zulip/32', 'text': '#32'}]

Similarly, the topic_links local echo logic in the frontend now returns
back an object.

Fixes: #17109.

Sumanth V Rao 7f6fe128f6 hotspots: Add TUTORIAL_ENABLED setting to toggle INTRO_HOTSPOTS.
We add a TUTORIAL_ENABLED setting for self-hosters who want to

default value (True) is placed in default_settings.py, which
can be overwritten by adding an entry in /etc/zulip/settings.py.

lukem1 105a5a95ee topic_mutes: Filter deactivated streams from get_topic_mutes.
Updated database query to filter out deactivated streams from the
return of the get_topic_mutes method. Added optional
include_deactivated parameter to the method to make the behavior
default but overrideable. Added test case in test_muting for these
changes. Fixes blueslip warnings thrown by muting.js set_muted_topics
when passed deactivated streams via page_params.

Mateusz Mandera f329878376 migrations: Subscription.is_user_active denormalization - step one.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.

To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.

sahil839 5b32dcd2e7 settings: Add moderators-only option in create_stream_policy.
This commit modifies the has_permission function to include
realm moderator role. Thus this adds a new option of moderators
only for create_stream_policy.
Though this automatically adds this option for invite_to_stream_policy
also, but we will keep other code for showing error and for tests
in a separate commit.

Alex Vandiver 134db206a9 outgoing_webhook: Set an X-Smokescreen-Role on requests.

Alex Vandiver cb3e6df8b9 outgoing_webhook: Add a requests session on the webhook.
The session object provides a common place to set headers on all
requests, no matter which implementation.

Because the `headers` attribute of Session is not a true static
attribute, but rather exposed via overriding `__getstate__`, `mock`'s
autospec cannot know about it, and thus throws an error; in tests that
mock the Session, we thus must explicitly set the `session.headers`.

Alex Vandiver a280905a89 outgoing_webhook: Join build_bot_request and send_data_to_server.
The existing organization, of returning an opaque blob from
`build_bot_request`, which was later consumed by
`send_data_to_server`, is not particularly sensible; the steps become
oddly split between the OutgoingWebhookWorker, `do_rest_call`, and the
`OutgoingWebhookServiceInterface`.

Make the `OutgoingWebhookServiceInterface` in charge of building,
making, and returning the request in one method; another method
handles extracting content from a successful response.  `do_rest_call`
is responsible for calling both halves of this, and doing common error
handling.

sahil839 fbf5ff26af tests: Fix stream creation part in comments of stream-policy tests.
The comments in stream-policy tests in test_message_send.py specifies
the restriction of creating streams based on stream_post_policy. But
this restriction was removed in 9aaa61963 and we now allow everyone to
create all type of streams. So this commit fixes the stream creation
parts in comments.

and fixed the documentation for /register and /events after the checking.

m-e-l-u-h-a-n 1b8a5a3344 markdown: Refactor backend logic for handling user mention.
Backend logic for handling user mention was cluttered
because it was handled at two stages first in
get_possible_mentions_info while fetching mention data
based on the messsage and then later in UserMentionPattern
which handles processing of text for mention.

Ideally UserMentionPattern should depend on
get_possible_mentions_info only for data but there was a
shared logic between these two that made it hard to debug
any possible bugs.

Updates in this commit make both of these functions
coherent in terms of logic and also add appropiate
comments to improve readability of these functions.

There was also a hidden bug that if a user A is
mentioned in with @**name|id** then @**invalid|id**
again mentioned A because of the way we handled mentions
earlier. It is solved as a result of this refactor and
appropiate test has been added for this.

This has been tested manually as well as by adding new
test to address missing case.

Tim Abbott 96c61a1a41 events: Fix broken custom_profile_fields events logic.
I noticed this because the test_events.py tests had the extremely
weird pattern of calling the actual change function, and then testing
the `notify` function's state changes (which should always be noops),
rather than actually testing the state change function.

Fixing the test made it clear that the actual logic in events.py
simply did not handle deleting custom_profile_field_value elements
from user objects when a custom_profile_field object was deleted.

So we fix that bit of logic as well.

It appears this bug was unique -- at least we don't have any other
notify_* functions being used directly in test_events.py, and the
handful of state_change_expected=False entries are all events for data
not present in page_params.

shanukun bc2d58ad4a custom_profile_fields: Remove op field for the event.
* `op` (operation) field, added in f6fb88549f, was never intended for
`custom_profile_fields` event. This commit removes the `op` as it doesn't
have any use in the code.

* As a part of cleanup, this also eliminates the schema check warnings
for `custom_profile_fields` event, mentioned in #17568.

m-e-l-u-h-a-n ffd4abaa4e logging: migrate test_import_export to use assertLogs.
This commit  migrates some of the backend tests in test_import_export
to use assertLogs(), instead of mock.patch() as planned in #15331.

Logs for tests in this file are suppressed and are not asserted as
that made changes to import/export codebase more fragile. As we
already have checks for the actual functionalities, it made less
sense to assert those logs.

m-e-l-u-h-a-n 2699048208 markdown: Extend user mention syntax to support user_id for mentioning.
Extend our markdown system to support mentioning of users
by id also. Following these changes, it would be possible
to mention users with @**|user_id** and silently mention
using @_**|user_id**.

Main intention for extending the mention syntax is to make
it convenient for bots to mention a users using their ids. It
is to be noted that previous syntax are also supported.

Documentation tweaked by tabbott for better readability.

The changes were tested manually in development server, and also
by adding some new backend and frontend tests.

Fixes: #17487.

akshatdalton 9c6d8d9d81 markdown: Add support to shorten GitHub links.
We add support to shorten links and test their shortening in
well-organized, clean manner that makes it trivial to extend the
GitHub approach for GitLab and perhaps other services.

We only shorten basic types of GitHub links (issue, PR, commit) that
fit a set of simple common patterns; the default behaviour of Autolink
is kept for everything else.

Logic added in frontend and backend Markdown Processor is identical.
This makes easy to extend the logic for other services like GitLab.

sahil839 683b6f7d65 tests: Refactor test_can_create_streams and test_can_subscribe_other_users.
We refactor test_can_create_streams and test_can_subscribe_other_users
in test_subs.py. We want to follow a specific order in such tests
which is just set the policy value one by one and then checking
that the role in policy returns true and role just below that returns
false. This approach is explained in detail below.

Following hierarchy of roles is considered for these tests -
1. Realm admin
2. Full members
3. Members
4. Guests.

Then if the policy is set to admins only, we check that the having
role as admin returns true and the role just below that, i.e. full
member returns false. Similarly, if the policy is set to members
only, we check that a member should return true and role below it
which is guest should return false. We basically follow these as
we can assume that if a user with particular role cannot do the
required task, then user with role below in the hierarchy would
be not allowed to do the task too.

This commit refactors the above mentioned two tests to have above
explained workflow.

sahil839 bc72d2dbc4 tests: Remove unnecessary use of do_change_user_role in test_subs.
This commit removes the unnecessary do_change_user_role function
in test_can_subcribe_other_users. This was added in 1aebf3cab
which replaced the multiple functions like do_change_is_admin
and do_change_is_guest with do_change_user_role.

Previously two functions do_change_is_admin and do_change_is_guest
were used because there were two flags is_realm_admin and is_guest
which were used to determine the role of a user. But then we added
a single field role to UserProfile and removed the multiple flags
and thus also replaced the different functions with a single
do_change_user_role. With addition of a new field role, two
different do_change_* functions were not needed as we only have
a role field instead of different flags, but this was missed in
1aebf3cab and this commit fixes it.

m-e-l-u-h-a-n 830c4acedc markdown: Fix invalid mention bug for stream and stream topic mention.
Modifies `StreamPattern` and `StreamTopicPattern` to inherit
from InlineProcessor instead of Pattern. This change is done
because Pattern stopped checking for matching patterns as soon
as it found a match which was not a valid stream. Due to this
all the subsequent mention failed, even if they were valid.
This bug was only present in backend renderring due to
markdown.inlinepatterns.Pattern.

Due to above changes verbose_compile is no longer used for
precompiling STREAM_LINK_REGEX, STREAM_TOPIC_LINK_REGEX as
adds ^(.*?) and (.*?)$ which cause extra overhead of matching
pattern which is not required. With new InlineProcessor these
extra patterns at beggining and end are not required.
So, StreamPattern and StreamTopicPattern now define their own
__init__ method for precompiling the regex.

Fixes #17535.

Aman Agrawal e587c029f6 display_settings: Allow user to set default_view.
TextField is used to allow users to set long stream + topic narrow
names in the urls.

We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.

This commit achieves 3 things:
* Removes recent topics as the default view which loads when
  hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
  other present UI elements.

NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view.  Ideally, we'd just display
the default view without a hash, but that involves extra complexity.

One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,

Cyril Pletinckx ba7da6d5c0 import/export: Fix deprecated authentication method for Slack.
The query string parameter authentication method is now deprecated for
newly created Slack applications since the 24th of February[1].  This
causes Slack imports to fail, claiming that the token has none of the
required scopes.

Two methods can be used to solve this problem: either include the
authentication token in the header of an HTTP GET request, or include
it in the body of an HTTP POST request. The former is preferred, as
the code was already written to use HTTP GET requests.

Change the way the parameters are passed to the "requests.get" method
calls, to pass the token via the `Authorization` header.

test_signup: This test was wrong, because the inviter UserProfile was
from a different realm. Such a PreregistrationUser shouldn't be
considered valid.

test_tutorial: The direct call to internal_send_private_message was
using sender's realm as the realm argument which is not valid. It
doesn't lead to any error because the codepath seems to mostly not care
about the realm arg if the sender is a cross-realm bot. From my reading
of the code I think that wrong realm arg here would break user mentions,
because it makes its way to check_message() and then to
build_message_send_dict - but overall the message gets sent without
errors. Either way, this was a bug in the test and should be fixed.

According to tests we should not allow bot without owners to

But the code does not handle this and the related test passes
and raises error for case of bots without owner because the bot
is itself a new member.

is no bot owner and then raise error if there is no owner.

Shanu 7f196967ad event_queue: Remove internal fields being leaked to the API.
A few internal fields used for tracking which types of notifications
have already been sent for a given message, like `hander_id` and the
`push_notified` bundle of fields were being incorrectly included in
message events delivered to clients clients.

One could argue these fields might be useful hints to clients, but
because notifications can be triggered later on via
`missedmessage_hook`, they have no useful purpose in the API.

This commit move these extended event field on a `internal_data`
object within the event object, and delete this field in `contents()`
for call points that would serve data to clients.

Tweaked by tabbott to provide a cleaner interface.

We're not bumping API_FEATURE_LEVEL because these fields have always
been documented as being present only due to a bug, so no clients
should be expecting or relying on them.

m-e-l-u-h-a-n 0e6343c071 users: Clarify readability issues related to access_user_by_id.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.

In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
   to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
   changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
   format.

Changes were tested using ./tools/test-backend.

Steve Howell 1498b2ef69 apply_event: Fix broken deepcopy attempt for subs.
When we were getting an apply_event call for
a subscription/add event, we were trying not to
mutate the event itself, but this clumsy code
was still mutating the actual event:

    # Avoid letting 'subscribers' entries end up in the list
    for i, sub in enumerate(event['subscriptions']):
        event['subscriptions'][i] = \
            copy.deepcopy(event['subscriptions'][i])
        del event['subscriptions'][i]['subscribers']

This is only a theoretical bug.

The only person who receives a subscription/add
event is the current user.

And it wouldn't have affected the current user,
since the apply_event was correctly updating the
state, and we wouldn't actually deliver the event
to the client (because the whole point of apply_event
is to prevent us from having to piggyback the
super-recent events on to our payload or put
them into the event queue and possibly race).

The new code just cleanly makes a copy of each
sub, if necessary, as we add them to state["subscriptions"].

And I updated the event schemas to reflect that
subscribers is always present in subscription/add
event.

Long term we should probably avoid sending subscribers
on this event when the clients don't set something
like include_subscribers.  That's a fairly complicated
fix that involves passing in flags to ClientDescriptor.
Alternatively, we could just say that our policy is
that we never send subscribers there, but we instead
use peer_add events.  See issue #17089 for more
details.

Steve Howell d9740045a5 refactor: Eliminate checks in build_stream_dict_for_sub.
We eliminate some redundant checks.

We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers.  We therefore bump
the API version and tweak the docs.  (See further
down for a detailed justification of the change.)

Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.

So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.

Anyway, it makes more sense to do these checks explicitly
in the validate function.

The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info.  The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.

Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.

The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):

    if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
        sub.subscribers = new LazySet([]);
    }

The webapp calculates access based on booleans, anyway:

    sub.can_access_subscribers =
        page_params.is_admin || sub.subscribed ||
        (!page_params.is_guest && !sub.invite_only);

And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:

    def get_other_subscribers_in_stream(<snip>):
        assert stream_id is not None or stream_name is not None

        if stream_id:
            assert self.is_user_subscribed_to_stream(stream_id)

            return [sub
                    for sub in self.stream_dict[stream_id]['subscribers']
                    if sub != self.user_id]
        else:
            return [sub
                    for _, stream in self.stream_dict.items()
                    for sub in stream['subscribers']
                    if stream['name'] == stream_name
                    if sub != self.user_id]

You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:

    result: Dict[int, List[int]] =
        {stream["id"]: [] for stream in stream_dicts}

If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).

Checking for `validate_email_not_already_in_realm` again (after the

this can even trigger a 500 error from PostgreSQL.

Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`.  The latter is

Siddharth Asthana 6c888977a6 change_subdomain: Create a deactivated realm on updating subdomain.
When changing the subdomain of a realm, create a deactivated realm with
the old subdomain of the realm, and set its deactivated_redirect to the
new subdomain.
Doing this will help us to do the following:
- When a user visits the old subdomain of a realm, we can tell the user
that the realm has been moved.
- During the registration process, we can assure that the old subdomain
of the realm is not used to create a new realm.

If the subdomain is changed multiple times, the deactivated_redirect
fields of all the deactivated realms are updated to point to the new
uri.

Steve Howell c5dc9d386f refactor: Use sets of stream_ids for email digests.
I now use sets for stream_ids in more of the digest
code.

As part of this I replaced exclude_subscription_modified_streams
with streams_recently_modified_for_user.

It's easier for the caller to just ask for ids
to delete from its callee than it is to pass
in a set/list to mutate.

The simpler boundary between the functions makes
the tests easier to write--you can see the
`filtered_streams` logic goes away in this diff.

I also make the tests a bit more thorough by using
combinations of Cordelia/Othello and Verona/Denmark
to try to find multiple possible flaws.

And I make the time intervals longer than 1s to
avoid false negatives from slow CI boxes.

Steve Howell 88a57ed4ac bulk digest: Get stream subscriptions in bulk.
If we have multiple users, this reduces the amount
of queries we need to do, because we get all
subscriptions for all users in a single query
to Subscription.

For the single-user case, we are introducing an
extra query hop, but the database is doing
roughly the same work, because we are just breaking
up this complex query into two hops:

    messages =
        select ...  from message
        where recipient__type_id in (
            select stream_id from subscription
            where ...
        )

Now it's more like:

    stream_ids =
        select stream_id from subscription
        where ...

    messages =
        select ... from message
        where recipient__type_id in stream_ids

Steve Howell c1f134a3a4 performance: Use ORM to fetch sender in render_markdown.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.

It's better to just let the ORM fetch this.  The
message object should already have sender.

The diff makes it look like we are saving round trips
to the database, which is true in some cases.  For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache.  The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).

Steve Howell 637f596751 tests: Fix queries_captured to clear cache up front.
Before this change we were clearing the cache on
every SQL usage.

The code to do this was added in February 2017
in 6db4879f9c.

Now we clear the cache just one time, but before
the action/request under test.

Tests that want to count queries with a warm
cache now specify keep_cache_warm=True.  Those
tests were particularly flawed before this change.

In general, the old code both over-counted and
under-counted queries.

It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL.  Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.

The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away.  And that's essentially
what the prior code simulated.

Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database.  There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.

Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.

This commit removes mock.patch with assertLogs().

* Adds return value to do_rest_call() in outgoing_webhook.py, to
  support asserting log output in test_outgoing_webhook_system.py.

* Logs are not asserted in test_realm.py because it would require to users
  to be queried using users=User.objects.filter(realm=realm) and the order
  of resulting queryset varies for each run.

* In test_decorators.py, replacement of mock.patch is not done because
  I'm not sure if it's worth the effort to replace it as it's a return
  value of a function.

Harsh Srivastava 9b31df009b openapi: Fix excessively large test_events failure output.
Because of the very large `oneOf` clause of the formats of events
possible in Zulip's `GET /events` system, we had issues with
`test-backend` failures for missing documentation for a new event
format being like 1000 lines of output, which was very much unhelpful.

Fix this by limiting the output use only the oneOf variants that are
broadly similar to the actual payload received.

Fixes #16023.

Mateusz Mandera 48f80fcb0a auth: Expect name in request params in Apple auth.
The name used to be included in the id_token, but this seems to have
been changed by Apple and now it's sent in the `user` request param.

https://github.com/python-social-auth/social-core/pull/483 is the
upstream PR for this - but upstream is currently unmaintained, so we
have to monkey patch.

We also alter the tests to reflect this situation. Tests no longer put
the name in the id_token, but rather in the `user` request param in the
browser flow, just like it happens in reality.

An adaptation has to be made in the native flow - since the name won't
be included by Apple in the id_token anymore, the app, when POSTing
to the /complete/apple/ endpoint,
can (and should for better user experience)
add the `user` param formatted as json of
{"email": "hamlet@zulip.com", "name": {"firstName": "Full", "lastName": "Name"}}
dict. This is also reflected by the change in the
native flow tests.

Steve Howell 7ff3859136 subscriber events: Change schema for peer_add/peer_remove.
We now can send an implied matrix of user/stream tuples
for peer_add and peer_remove events.

The client code basically does this:

    for stream_id in event['stream_ids']:
        for user_id in event['user_ids']:
            update_sub(stream_id, user_id)

We used to send individual events, which gets real
expensive when you are creating new streams. For
the case of copy-to-stream case, we should see
events go from U to 1, where U is the number of users
added.

Note that we don't yet fully optimize the potential
of this schema.  For adding a new user with lots
of default streams, we still send S peer_add events.

And if you subscribe a bunch of users to a bunch of
private streams, we only go from U * S to S; we can't
optimize it down to one event easily.

Steve Howell 85ed6f332a performance: Avoid Recipient lookup for stream messages.
All the fields of a stream's recipient object can
be inferred from the Stream, so we just make a local
object.  Django will create a Message object without
checking that the child Recipient object has been
saved.  If that behavior changes in some upgrade,
we should see some pretty obvious symptom, including
query counts changing.

Tweaked by tabbott to add a longer explanatory comment, and delete a
useless old comment.

We already trust ids that are put on our queue

We now pass stream_recipient_id when we queue
up work for do_mark_stream_messages_as_read.

This generally saves about 3 queries per
user when we unsubscribe them from a stream.

      and recipient data being returned in the
      query.

    * We avoid Django making extra hops to the
      database to get user info.
2020-10-16 12:58:11 -07:00
Steve Howell b4346d0276 performance: Extract subscribers/peers in bulk.
We replace get_peer_user_ids_for_stream_change
with two bulk functions to get peers and/or
subscribers.

Note that we have three codepaths that care about
peers:

    subscribing existing users:
        we need to tell peers about new subscribers
        we need to tell subscribed user about old subscribers

    unsubscribing existing users:
        we only need to tell peers who unsubscribed

    subscribing new user:
        we only need to tell peers about the new user
        (right now we generate send_event
        calls to tell the new user about existing
        subscribers, but this is a waste
        of effort that we will fix soon)

The two bulk functions are this:

    bulk_get_subscriber_peer_info
    bulk_get_peers

They have some overlap in the implementation,
but there are some nuanced differences that are
described in the comments.

Looking up peers/subscribers in bulk leads to some
nice optimizations.

We will save some memchached traffic if you are
subscribing to multiple public streams.

We will save a query in the remove-subscriber
case if you are only dealing with private streams.

Steve Howell a9356508ca events: Stop sending occupy/vacate events.
We used to send occupy/vacate events when
either the first person entered a stream
or the last person exited.

It appears that our two main apps have never
looked at these events.  Instead, it's
generally the case that clients handle
events related to stream creation/deactivation
and subscribe/unsubscribe.

Note that we removed the apply_events code
related to these events.  This doesn't affect
the webapp, because the webapp doesn't care
about the "streams" field in do_events_register.

There is a theoretical situation where a
third party client could be the victim of
a race where the "streams" data includes
a stream where the last subscriber has left.
I suspect in most of those situations it
will be harmless, or possibly even helpful
to the extent that they'll learn about
streams that are in a "quasi" state where
they're activated but not occupied.

We could try to patch apply_event to
detect when subscriptions get added
or removed. Or we could just make the
"streams" piece of do_events_register
not care about occupy/vacate semantics.
I favor the latter, since it might
actually be what users what, and it will
also simplify the code and improve
performance.

Steve Howell 1bcb8d8ee8 performance: Avoid computing page_params.streams in webapp.
The query to get "occupied" streams has been expensive
in the past.  I'm not sure how much any recent attempts
to optimize that query have mitigated the issue, but
since we clearly aren't sending this data, there is no
reason to compute it.

Aman Agrawal fbf7cb82a7 web_public_guest: Rename to web_public_visitor for clarity.
Using web_public_guest for anonymous users is confusing since
'guest' is actually a logged-in user compared to

read access to messages. So, we rename it to
web_public_visitor.

Steve Howell e7a8c7ac48 test: Improve tests for bulk-adding subscribers.
This is a more thorough test of adding multiple
streams for multiple users, including streams
that users have already subscribed to.

The extra queries here are due to the fact
that we call `principal_to_user_profile` in
a loop in the view.  So that's an example
of O(N) overhead.  We may be able to bulk-fetch
these users eventually.

Steve Howell c29ba75135 refactor: Extract send_messages_for_new_subscribers.
This is a pure extraction, except that I remove a
redundant check that `len(principals) > 0`.  Whenever
that value is false, then `new_subscriptions` will
only have one possible entry, which is the current
user, and we skip that in the loop.

Steve Howell 3b338ec32e performance: Optimize filter_stream_authorization.
We no longer do O(N) queries to get existing streams.

This is a somewhat contrived use case--generally, we
are not trying to re-subscribe a user to several
streams.  Still, we want to avoid this.

This commit also makes `test_bulk_subscribe_many`
do more work, and the change to the test helped
me discover this bug.

This may be overkill--I would also be happy if we
