We now add `realm_non_active_users` to the result of
`do_events_register` (and thus `page_params`). It has
the same structure as `realm_users`, but it's for
non-active users. Clients need data on non-active users
when they process old messages that were sent by those
users when they were active. Clients can currently get
most of the data they need in the message events, but it
makes for ugly client code.
Fixes#4322
This is a prepatory commit that adds non-active users to
the realm user cache. It mostly involves name changes and
removing an `is_active` filter from the relevant DB query.
The only consumer of this cache is `get_raw_user_data`, which
now filters on `is_active` in a dictionary comprehension (but
this will get moved around a bit in a subsequent commit).
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.
If an organization doesn't have the EmailAuthBackend (which allows
password auth) enabled, then our password reset form doesn't do
anything, so we should hide it in the UI.
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`.
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.
We now return user_ids for subscribers to streams in add-stream
events. This allows us to eliminate the UserLite class for
both bulk adds and bulk removes. It also simplifies some JS
code that already wanted to use user_ids, not emails.
Fixes#6898
The logic to apply events to page_params['unread_msgs'] was
complicated due to the aggregated data structures that we pass
down to the client.
Now we defer the aggregation logic until after we apply the
events. This leads to some simplifications in that codepath,
as well as some performance enhancements.
The intermediate data structure has sets and dictionaries that
generally are keyed by message_id, so most message-related
updates are O(1) in nature.
Also, by waiting to compute the counts until the end, it's a
bit less messy to try to keep track of increments/decrements.
Instead, we just update the dictionaries and sets during the
event-apply phase.
This change also fixes some corner cases:
* We now respect mutes when updating counts.
* For message updates, instead of bluntly updating
the whole topic bucket, we update individual
message ids.
Unfortunately, this change doesn't seem to address the pesky
test that fails sporadically on Travis, related to mention
updates. It will change the symptom, slightly, though.
We don't need full Realm objects to find DefaultStream
objects for a realm. So now a few functions related to
adding/removing default streams use realm_id for lookups.
Similarly, we don't need a full Stream object to find
out if a stream exists in DefaultStream, so we do id
lookups there as well.
This sets us up to use thinner objects in callers.
This is mostly pure code extraction.
It also removes some dead code in update_muted_topic, where
were updating muted_topics spuriously before calling
do_update_muted_topic.
This field is convenient for bankruptcy checks. Clients could
calculate it from page_params.unread_msgs before this change, but
it would kind of a painful calculation.
To add count, we had to simplify the mypy annotations, which weren't
really accurate before.
We are adding a new list of unread message ids grouped by
conversation to the queue registration result. This will allow
clients to show accurate unread badges without needing to load an
unbound number of historic messages.
Jason started this commit, and then Steve Howell finished it.
We only identify conversations using stream_id/user_id info;
we may need a subsequent version that includes things like
stream names and user emails/names for API clients that don't
have data structures to map ids -> attributes.
This system hasn't been in active use for several years, and had some
problems with it's design. So it makes sense to just remove it to declutter
the codebase.
Fixes#5655.
This makes it possible for Zulip administrators to delete messages.
This is primarily intended for use in deleting early test messages,
but it can solve other problems as well.
Later we'll want to play with the permissions model for this, but for
now, the goal is just to integrate the feature.
Note that it saves the deleted messages for some time using the same
approach as Zulip's message retention policy feature.
Fixes#135.
This is probably not the right long-term solution to the cross-realm
bots problem (that solution is probably to eliminate cross-realm bots
and replace them with per-realm bots). But in the short term, this
will at least make it possible for mobile apps to interact with these
cross-realm bots using the `realm_user` data set.
Due to the refactoring of the avatar URL codepath that added realm IDs
to the URLs, we ended up calling `get_user_profile_by_email` inside
`get_avatar_url`, which in turns was called in a loop over all users
in a realm.
Needless to say, this resulted in a significant performance problem.
We fix this issue by passing in the data needed to compute the avatar
URL, rather than looking it up by email address.
Move the user_profile data section down into fetch_initial_state_data
so it entirely pulls from register_ret for #3853.
This field requires some changes to the events race handling.
This moves the avatar_ fields in page_params to come from
register_ret. Unlike many fields, changing this had a bit of
complexity, because the avatar update events didn't actually contain
some of the details required for moving these into register_ret to
work correctly without races.
We fix that as part of this change.
