Previously, we weren't doing a proper left join in
user_groups_in_realm_serialized, resulting in empty user groups being
excluded from the query. We want to leave decisions about excluding
empty user groups to the UI layer, so we include these here.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak. While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.
Fixes#7095.
This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
This fixes a regression in ae5ba7f4fd,
where Zulip would 500 if the newly added system bots didn't exist on
the server.
This also fixes a moderate size performance problem where we'd fetch 5
users from memcached or the database in a loop.
These are new:
new-user-bot
emailgateway
Our cross-realm bots are hard coded to have email addresses
in the `zulip.com` domain, and they're not part of ordinary
realms.
These have always been cross-realm, but new enforcement in the
frontend code of all messages having been sent by a known user means
that it's important to add these properly.
This change affects realm_users and realm_non_active_users.
Note that we still send full avatar urls in realm_user/add
events, so apply_events has to do something mildly hacky to
turn the avatar_url to None in that case.
Fixing the event is probably not worth the trouble, as single
urls are not bandwidth hogs; we only need this optimization
for bulk data.
This change affects these values:
* page_params.avatar_url
* page_params.avatar_url_medium
It requires passing the client_gravatar flag through this
codepath:
* home_real
* do_events_register
* fetch_initial_state_data
* avatar_url
This commit allows clients to register client_gravatar=True, and
then we recognize that flag for message events. If the flag is
True, we will not calculate gravatar URLs and let the clients do
it themselves. (Clients can calculate gravatar URLs based on
emails with just a little bit of code.)
This refactoring doesn't change behavior, but it sets us up
to more easily handle a register setting for `client_gravatar`,
which will allow clients to tell us they're going to compute
their own gravatar URLs.
The `client_gravatar` flag already exists in our code, but it
is only used for Django views (users/messages) but not for
Zulip events.
The main change is to move the call to `set_sender_avatar` into
`finalize_payload`, which adds the boolean `client_gravatar`
parameter to that function. And then we update various callers
to supply that flag.
One small performance benefit of this change is that we now
lazily compute the client message payloads in
`event_queue.process_message_event` now, so this will improve
performance if all interested clients have the same value of
`apply_markdown`. But the change here is really preparing us
for the additional boolean parameter, which will cause us to
have four variations of the payload.
Do you call get_recipient(Recipient.STREAM, stream_id) or
get_recipient(stream_id, Recipient.STREAM)? I could never
remember, and it was not very type safe, since both parameters
are integers.
We mostly introduce these functions (as part of a big
code sweep):
send_stream_message
send_personal_message
send_huddle_message
In two cases, where we want to specifically manipulate
queue ids, we now call check_send_message directly. (The
above three functions deliberately don't support kwargs
to ensure simple code and better type safety.)
In do_send_messages, we only produce one dictionary for
the event queues, instead of different flavors for text
vs. html. This prevents two unnecessary queries to the
database.
It also means we only put one dictionary on the "message"
event queue instead of two, albeit a wider one that has
some values that won't be sent to the actual clients.
This wider dictionary from MessageDict.wide_dict is also
used for the `feedback_messages` queue and service bot
queues. Since the extra fields are possibly useful down
the road, and they'll just be ignored for now, we don't
bother to remove them. Also, those queue processors won't
have access to `content_type`, which they shouldn't need.
Fixes#6947
We make a few things cleaner for populating `realm_users`
in `do_event_register` and `apply_events`:
* We have a `raw_users` intermediate dictionary that
makes event updates O(1) and cleaner to read.
* We extract an `is_me` section for all updates that
apply to the current user.
* For `update` events, we do a more surgical copying
of fields from the event into our dict. This
prevents us from mutating fields in the event,
which was sketchy (at least in test mode). In
particular, this allowed us to remove some ugly
`del` code related to avatars.
* We introduce local vars `was_admin` and `now_admin`.
The cleanup had two test implications:
* We no longer need to normalize `realm_users`, since
`apply_events` now sees `raw_users` instead. Since
`raw_users` is a dict, there is no need to normalize
it, unlike lists with possibly random order.
* We updated the schema for avatar updates to include
the two fields that we used to hackily delete from
an event.
This new test solves the problem that when we
made changes to the page-load codepath in the past,
it's been hard to identify what new code caused
more database queries. Now you can see query
counts broken out by event type.
This requires a small, harmless change to extract
an `always_want` function in `lib/events.py`.
This field would get overwritten with an improper value when
we looped over multiple clients, due to not making full copies
of the message dictionary. This failure would be somewhat
random depending on how clients were ordered in the loop.
The only consumers of this field were the mobile app and the
apply-events-to-unread-counts logic. Both of these will now
use `flags` instead.
The `is_mentioned` flag in message events was buggy. We now
look directly at flags.
We will kill off `is_mentioned` in a subsequent commit.
We also remove some debugging code in the test that was failing
before this fix. The test would only fail when `is_mentioned`
was wrong, which never happened when you ran a single test, and
which would happen randomly when you ran multiple tests.
