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.

Fixes: #15947.

Mateusz Mandera 90636d5e81 events: Fix bug in get_recent_conversations_recipient_id.
user_profile.id was confused for user_profile.recipient_id. These bugs
are particularly sneaky as they can go undetected by tests due to ids of
objects accidentally coinciding. We add a mitigation for this class of
mistakes by shifting the Recipient.id sequence in test db.

This was introduced in dda3ff41e1.
On the rare occasion where user_profile.id would coincide with
recipient_id passed to the function, we would return the wrong value.
That is, instead of correctly returning recipient_id, we would return
sender.recipient_id - recipient id of the sender of the message, thus
possibly returning user_profile.recipient_id (if user_profile is the
sender) - exactly the situation the function wanted to avoid
with the `if recipient_id == my_recipient_id:` if. Ultimately resulting
in incorrect/malformed data in
state['raw_recent_private_conversations'].

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.

Fixes #17111.

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 c6acde9c63 apply_event: Use stream_ids, not names, for add/remove.

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).

Note that as part of this we eliminated
a failure mode for the obscure population
of users from whom both `user.is_guest` and
`user.can_access_public_streams()` returns
False.  We know this would have only affected
Zephyr users (by looking at the code), and
we know we don't actually process Zephyr
users for email digests (or else we would
have raised exceptions in the old code).

Mateusz Mandera 3623681d30 message_edit: Don't rely on .recipient_id change not affecting recipient.
The codepath for moving a topic changes the message.recipient_id to the
id of the new recipient, but later, in update_messages_for_topic_edit,
it uses message.recipient when querying for messages with the matching
topic in the *old* stream (because those are the other messages that
need to be moved). This is a bug which happens to work fine, because in
Django 2, if message.recipient gets fetched first and then
message.recipient_id is mutated, message.recipient will not be altered
and thus will retain the outdated, previously fetched value.

In Django 3 changing .recipient_id causes .recipient to be updated to
the new Recipient objects, which is the Recipient of the *new* stream.
That will cause the bug to manifest.

This is a bugfix preparing for the upgrade to Django 3.

Tushar912 c60f48c889 registration: Move "already in realm" check outside of validation.
Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check.  In the case of emails containing nulls,
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
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Fixes #17015.

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.

sahil839 2fa33be683 actions: Refactor check_message to change return dataclass instead of Dict.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.

SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.

We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.

sahil839 37c8505435 message: Raise exception when trying to mirror an already sent message.
Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.

This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.

This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.
2020-12-18 16:40:11 -08:00
sahil839 4e99ec34a9 widget: Use different variable names for message and submessage content.
This commit renames the content variable in do_widget_post_save_actions
to message_content and is a prep commit for changing the return type of
check_message from Dict to dataclass.

This change is required because content variable is used two times in
this function - one for message content and other for submessage
content, so when we change the return type of check_message to
dataclass, the type of content variable is considered as str and then
when dict is assigned to content in the submessage case, mypy raises
'Incompatible types in assignment' error.

This issue is not faced before the dataclass migration because there is
no type checking for the values of dict returned by check_message as the
return type of check_message is 'Dict[str, Any]'.

Puneeth Chaganti 358f1f9ba7 webhooks/sentry: Support integration configured as webhook.
Sentry allows adding simple webhooks without going through the process
of creating an Internal Integration in Sentry's Integration
Platform[1] (which our docs recommend).

The payload from sent from such a (simple) webhook integration is
slightly different from the payload sent by an Internal Integration
webhook. This commit tries to wrangle this payload into a form that is
usable by our webhook handler to send a notification message.

akshatdalton 806c1a0b8b markdown: Fix flickering of embedded link inside Italic.

was adjacent to the others that needed it in the file.

Fix this, and add tests to verify that things are still being escaped

Steve Howell e8b6c56322 refactor: Simplify get_hot_topics().
The code we deleted here was no longer
doing anything.

Maybe the code was always dead, or maybe it
was written during a time when topics_by_diversity
and topics_by_length actually had different keys.

But now it's clearly cruft.

If we have 4 or more topics, then the code above
it would already have populated the list with 4
elements, and the `if num_convos < 4` condition
would evaluate to False.

And if we had 3 or fewer topics, then we would
have already put all possible topics into our
result, and the `topics_by_diversity[num_convos:4]`
slice would be empty.

It's possible that we should just have a simple
heuristic for topic hotness like `10*num_senders
+ messages`, so we don't have to maintain this
fiddly function, and we can just do something like
`topics_by_score[:4]`.

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

This prep step is mostly for diff hygiene; the next

The original code here had the nice property that
most (but not all) of the DB work happened up
front in `handle_digest_email`, and none of the
DB work was delegated to the callers.  But I
prefer the tradeoff of making the helpers a bit
more cohesive--let them get the data they need.
And we have query-count coverage in our tests,
so there's no real danger of having helpers
down in the stack insidiously doing a bunch of
extra DB hops.

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).
2020-11-05 09:35:15 -08:00
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.

Tim Abbott 6d7cd351a3 events: Optimize creating streams for new users.
During the new user creation code path, there can be no existing
active clients for the user being created, so we can skip the code to
send events to that user's clients.

queries that would have been spent computing data for these..

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 0b91526f28 events: Remove "occupied" semantics for "streams".
When apps like mobile register for "streams", we
will now just use active streams as our baseline,
rather than "occupied" streams.

This means we will send a stream that is active,
even if it happens to have zero occupants.  It's
actually pretty rare that a stream has zero occupants,
and it's not exactly clear that we want to exclude
a non-occupied but otherwise active stream from
our list of streams.

It also happens to be fairly expensive to compute
whether a stream is occupied.

This change only affects API clients (including
possibly our mobile app).  The main webapp never
used the data from this codepath.

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.
