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.
This add the schema checker, openapi schema, and also a test for
realm/deactivated event.
With several block comments by tabbott explaining the logic behind our
behavior here.
Part of #17568.
We discovered recently that some ops for events were just not
implemented in events.py (specifically, realm/deactivated).
Since our goal is for events.py to be complete, we add this bit of
hardening to ensure that it stays that way.
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.
It's always cleaner to work in id space. It probably
would have required a perfect storm to have broken
the existing code, but using ids is obviously more
robust in theory, and just as simple.
We now require keywords, so that there is no
pitfall for mixing up boolean parameters.
Positional parameters are basically evil
when you have a bunch of bools.
I also make user_profile the first argument.
Finally, the code is more diff-friendly.
I eliminate the defaults, since the existing code
was already specificying values for most things.
I move all the booleans to the bottom for both
parameters and arguments.
I require explicit keywords for everything but
user_profile (which is now first).
And, finally, I format the code in a more
diff-friendly manner.
We now require explicit keywords for all arguments
to fetch_initial_state_data except user_profile.
We provide reasonable defaults to keep the test
code concise.
In 1bcb8d8ee8 I made
it so the webapp doesn't include "streams" in its
state from `fetch_initial_state_data`, but I didn't
address all the places in apply_event.
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.
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.
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.
user_profile will be None for web_public_guests here. Hence, for
settings (of which most be inaccessible by web public guest),
which require a user_profile, we either set an empty value for
them or set them to a default value. This will help render
the frontend or extend support to our clients without breaking
a lot of code.
Tweaked by tabbott to add many comments.
Some users setup zulip with trailing / at end, like 'https://meet.jit.si/
leading to extra / on clients while generating video chat link.
This commit removes trailing '/' if it exists to make it consistent. Manual
testing was done by generating jitsi url.
Fixes#16225
`update_message_flags` events used `operation` instead of `op`, the
latter being the standard field used in other events. So add `op`
field to `update_message_flags` and mark `operation` as deprecated,
so that it can be removed later.
JSON keys must be strings, and orjson enforces this. Mypy didn’t
catch the mismatched type of profiles_by_user_id because it doesn’t

There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
Because of other validation on these values, I don't believe any of
these does anything different, but these changes improve readability
and likely make GitHub's code scanners happy.
Two things were broken here:
* we were using name(s) instead of id(s)
* we were always sending lists that only
had one element
Now we just send "stream_id" instead of "subscriptions".
If anything, we should start sending a list of users
instead of a list of streams. For example, see
the code below:
if peer_user_ids:
for new_user_id in new_user_ids:
event = dict(type="subscription", op="peer_add",
stream_id=stream.id,
user_id=new_user_id)
send_event(realm, event, peer_user_ids)
Note that this only affects the webapp, as mobile/ZT
don't use this.
This adds a new client_capability that clients such as the mobile apps
can use to avoid unreasonable network bandwidth consumed sending
avatar URLs in organizations with 10,000s of users.
Clients don't strictly need this data, as they can always use the
/avatar/{user_id} endpoint to fetch the avatar if desired.
This will be more efficient especially for realms with
10,000+ users because the avatar URLs would increase the
payload size significantly and cost us more bandwidth.
Fixes#15287.
This line was effectively hardcoding a specific stream_post_policy,
overriding the value already present in the event, to no purpose.
(I believe it got here via cargo-culting induced by #13787.)
This commit removes is_old_stream property from the stream objects
returned by the API. This property was unnecessary and is essentially
equivalent to 'stream_weekly_traffic != null'.
We compute sub.is_old_stream in stream_data.update_calculated_fields
in frontend code and it is used to check whether we have a non-null
stream_weekly_traffic or not.
Fixes#15181.
This is designed to have no user-facing change unless the client
declares bulk_message_deletion in its client_capabilities.
Clients that do so will receive a single bulk event for bulk deletions
of messages within a single conversation (topic or PM thread).
Backend implementation of #15285.
Fixes#2665.

Note from tabbott: In a few cases, this converts technical debt in the

This was previously hardcoded with agreement between the Zulip backend
and frontend as 86400 seconds (1 day). Now, it's still hardcoded in
the backend, but arranged in a way where we could add a setting
without any changes to the mobile and terminal apps to update logic.
Fixes#15278.
This reimplements our Zoom video call integration to use an OAuth
application. In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

This commit changes the person dict in event sent by do_change_user_role
to send role instead of is_admin or is_guest.
This makes things much more straightforward for our upcoming primary
owners feature.
The `email` field for identifying the user being modified in these
events was not used by either the webapp or other official Zulip
clients. Instead, it was legacy data from before we switched years
ago to sending user_id fields as the correct way to uniquely identify
a user.
We remove the `owner` field from `page_params/realm_bots`
and bot-related events.
In the recent commit 155f6da8ba
we added `owner_id`, which we now use everywhere we need
bot owners for.
We also bump the `API_FEATURE_LEVEL` to 5 here. We
had already documented this in the prior commit to
add `owner_id`.
Note that we don't have to worry about mobile/ZT clients
here--we only deal with bot data in the webapp.
For the below payloads we want `owner_id` instead
of `owner`, which we should deprecate. (The
`owner` field is actually an email, which is
not a stable key.)
page_params.realm_bots
realm_bot/add
realm_bot/update
IMPORTANT NOTE: Some of the data served in
these payloads is cached with the key
`bot_dicts_in_realm_cache_key`.
For page_params, we get the new field
via `get_owned_bot_dicts`.
For realm_bot/add, we modified
`created_bot_event`.
For realm_bot/update, we modified
`do_change_bot_owner`.
On the JS side, we no longer
look up the bot's owner directly in
`server_events_dispatch` when we get
a realm_bot/update event. Instead, we
delegate that job to `bot_data.js`.
I modified the tests accordingly.
It's a preliminary step to enable message_retention_setting in org settings
UI, which is a non-limited plan only feature. So we require a page_param
property that tells us the limited-plan state of the Zulip realm.
This commit removes can_create_streams and can_subscribe_other_users
to use has_permission as a generic function in UserProfile model for
these settings policies.
Relevant changes are made to events.py to avoid duplication at some
places.
The purpose is to provide a way for (non-webapp) clients,
like the mobile and terminal apps, to tell whether the
server it's talking to is new enough to support a given
API feature -- in particular a way that
* is finer-grained than release numbers, so that for
features developed after e.g. 2.1.0 we can use them
immediately on servers deployed from master (like
chat.zulip.org and zulipchat.com) without waiting the
months until a 2.2 release;
* is reliable, unlike e.g. looking at the number of
commits since a release;
* doesn't lead to a growing bag of named feature flags
which the server has to go on sending forever.
Tweaked by tabbott to extend the documentation.
Closes#14618.
The previous starred_messages race handling did not correctly consider
the possibility that an event queue might have been registered without
starred_messages.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.
At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.
While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.
Fixes#14111.
We calculate `max_message_id` for the mobile client.
Our query now no longer joins to the Message table
and just grabs one value instead of fat objects.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
This flag affects page_params and the
payload you get back from POSTs to this
url:
users/me/presence
The flag does not yet affect the
presence events that get sent to a
client.
This moves get_cross_realm_dicts (from zerver.lib.actions),
get_raw_user_data and get_custom_profile_field_values (from
zerver.lib.events) to zerver.lib.users.
This extracts the user_data inner function from get_raw_user_data as a
reusable function. We intend to reuse it for cross-realm user dicts.
A few changes were made while extracting it:
* Renaming the UserProfile argument to acting_user, so we can do loops
over a local user_profile variable.
* Moved it to zerver.lib.users, as that's a more appropriate home for
this function formatting data on users.
* Simplified the calling convention for passing custom profile fields
to reflect the fact that this function processes a single user (and
is expected to be called in a loop).
This change should prevent test flakes, plus
it's more deterministic behavior for clients,
who will generally comma-join the ids into
a key for their internal data structures.
I was able to verify test coverage on this
by making the sort reversed, which would
cause test_huddle_send_message_events to
fail.
This should be about 4 times faster, saving something like half a
millisecond on each stream of 10000 subscribers.

This simple change switches us to take advantage of the
server-maintained data for the pm_conversations system we implemented
originally for mobile use.
This should make it a lot more convenient to find historical private
message conversations, since one can effectively scroll infinitely
into the history.
We'll need to do some profiling of the backend after this is deployed
in production; it's possible we'll need to add some database indexes,
denormalization, or other optimizations to avoid making loading the
Zulip app significantly slower.
Fixes#12502.
This fixes two regressions in 1946692f9a.
The first bug was actually introduced much earlier, namely that we
were not sending a `bot_owner_id` field at all for bot users without
an owner. The correct behavior would have been send `None` for the
owner field.
The second bug was simply that we needed to update the webapp to look
for the `bot_owner_id` field, rather than an old email-address format
`bot_owner` field.
Thanks to Vinit Singh for reporting this bug.
Previously, we were using user_profile.email rather than
user_profile.delivery_email in all calculations involving Gravatar
URLs, which meant that all organizations with the new
EMAIL_ADDRESS_VISIBILITY_ADMINS setting enabled had useless gravatars
not based on the `user15@host.domain` type fake email addresses we
generate for the API to refer to users.
The fix is to convert these calculations to use the user's
delivery_email. Some refactoring is required to ensure the data is
passed through to the parts of the codebase that do the check;
fortunately, our automated tests of schemas are effective in verifying
that the new `sender_delivery_email` field isn't visible to the API.
Fixes#13369.
This patches an issue in f37535044 where we mistakenly tried to send
the function as part of the page_params. Instead, we should just try
to send the list of configuration options (in their user displayable
form).
Send the config_options for each supported incoming webhook bot along
with the initial state (not present in apply_events since this is
mostly just static data).
This feature is intended to cover all of our ways of exporting a
realm, not just the initial "public export" feature, so we should name
things appropriately for that goal.
Additionally, we don't want to include data exports in page_params;
the original implementation was actually buggy and would have.
Add new custom profile field type, External account.
External account field links user's social media
profile with account. e.g. GitHub, Twitter, etc.
Fixes part of #12302
Namely, here we add the "plan_includes_wide_organization_logo" and
"upgrade_text_for_wide_organization_logo" to the page_params (which
is set in zerver/lib/events.py).
"plan_includes_wide_organization_logo" is True if the plan is not of
the Realm.LIMITED type. We need to add this extra boolean parameter
instead of just using "realm_plan_type" to make things a lot easier
to work with on the frontend side, especially considering that
handlebars won't allow checking for equality in its {{#if}} blocks.
When a realm's plan type is updated using "do_change_plan_type" we
notify active users of the realm. This way certain plan features
could be enabled instantaneously for active users.
Modifies the dict with the user info to include the key `bot_owner_id`
so it can be displayed in the user info popover.
Tests concerned with changing bot owner have been modified to have
number of events=2 because while updating the bot info, two events
are fired -- updating the `realm_bot` and `realm_user` since the
key `bot_owner_id` is a part of realm user info.
Clients won't have access to user email addresses, and thus won't be
able to compute gravatars.
The tests for this are a bit messy, in large part because our tests
for get_events call subsections of it, rather than the main function.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.
Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.
The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side. We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.
This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.
This commit replaces the `create_stream_by_admins_only` setting with a
new `create_stream_policy` setting, which mirroring the structure of
the existing `invite_to_stream_policy`.
This is important preparation for migrating the waiting period feature
to be its own independent setting.
Fixes#12236.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
An endpoint was created in zerver/views. Basic rate-limiting was
implemented using RealmAuditLog. The idea here is to simply log each
export event as a realm_exported event. The number of events
occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.
The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.
Upon completion of the export the realm admin(s) are notified.
This is important because upcoming features will include slightly more
complex logic in post_process_state that we'd ideally like to be
included in what this suite tests.
This requires a few related changes:
* A small change to post_process_state to sort the realm_users objects
by user_id to ensure those data structures are stable.
* Improvements to the logic for checking if the initial state has
changed to use match_states for better output.
This adds experimental support in /register for sending key
statistical data on the last 1000 private messages that the user is a
participant in. Because it's experimental, we require developers to
request it explicitly in production (we don't use these data yet in
the webapp, and it likely carries some perf cost).
We expect this to be extremely helpful in initializing the mobile app
user experience for showing recent private message conversations.
See the code comments, but this has been heavily optimized to be very
efficient and do all the filtering work at the database layer so that
we minimize network transit with the database.
Fixes#11944.
This field is primarily intended to support avoiding displaying the
"more topics" feature in new organizations and streams, where we might
know that all messages in the stream are already available in the

tabbott.
The second migration involved here could be expensive on Zulip Cloud,
but is unlikely to be an issue on other servers.
The night logo synchronization on the settings page was perfect, but
the actual display logic had a few problems:
* We were including the realm_logo in context_processors, even though
it is only used in home.py.
* We used different variable names for the templating in navbar.html
than anywhere else the codebase.
* The behavior that the night logo would default to the day logo if
only one was uploaded was not correctly implemented for the navbar
position, either in the synchronization for updates code or the
logic in the navbar.html templates.
Guest users will just get an empty list of default streams; we also
hide the "Default streams" organization view from the guest users UI.
This is for consistency with not providing guest users the full list
of streams in an organization.
Fixing this involves fixing the backend to handle unchanged field
submissions of the Zoom credentials without trying to re-validate the
credentials (for performance) as well as to fetch the already-sent
secret.
Add all the stop words to page_params, reading from the
`zulip_english.stop` database, with caching to avoid loading the file
on every page load.
Part of #10592.
This commit does the following three things:
1. Update stream model to accomodate rendered description.
2. Render and save the stream rendered description on update.
3. Render and save stream descriptions on creation.
Further, the stream's rendered description is also sent whenever the
stream's description is being sent.
This is preparatory work for eliminating the use of the
non-authoritative marked.js markdown parser for stream descriptions.
You can now pass in an info field with a value
like "out to lunch" to the /users/me/status,
and the server will include that in its outbound
events.
The semantics here are that both "away" and
"status_text" have to have defined values in order
to cause changes. You can omit the keys or
pass in None when values don't change.
The way you clear info is to pass the empty
string.
We also change page_params to have a dictionary
called "user_status" instead of a set of user
ids. This requires a few small changes on the
frontend. (We will add "status_text" support in
subsequent commits; the changes here just keep
the "away" feature working correctly.)
This makes it possible it include our standard markdown formatting in
one's custom profile fields, allowing for links, emphasis, emoji, etc.
Fixes#10131.
While we're at it, we remove the JSON parsing that was part of the
user field code path, since this function isn't responsible for
rendering user fields.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.
Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
notifications settings are requested.

This commit add FIELD_TYPE_CHOICES_DICT to page_params and replace
FIELD_TYPE_CHOICES.
FIELD_TYPE_CHOICES_DICT includes all field types with keyword, id

field-type'a name or id in frontend.
This commit also modifies functions in js where this page_params

I don't understand why this didn't cause test failures in CI; this

Users in the waiting period category cannot subscribe other users to
a stream. When a user tries to mention another unsubscribed user, a
warning message appears with a subscribe button on it to subscribe
the other user.

* No need to delete the invite list in frontend, current logic
handles the case when the invite data is changed properly.
* Extracted the common logic for sending an event into
`notify_invites_changed`.
Custom profile field value are stored in different structure compare to
other profile fields in events, so generic way to update fields wasn't
updating custom profile fields in `apply_event` function.
Fix this by adding check for custom fields in `apply_event`.
This also adds the appropriate test_events test to verify this code path.
Fixes part of #9875.
