The tool needs to run this function, since it uses django's send_email
directly instead of going through our zerver.lib.send_email.send_email
codepath.
The message ID is encoded in the URL, not the PATCH parameters, so
this argument was ignored. I verified that it appears to have always
matched the value present in the URL.
The new logic better matches reasonable user expectations, that if you
move all the messages, that's a whole-topic move, regardless of which
propagation mode you selected.
When moving only part of a topic, it's useful to display that
information to users in these notifications so that it's clear what's
happening.
The most important consequence is actually just increasing confidence
that when you see that the whole topic was moved, that's accurate.
Substantially modified by tabbott.
Fixes#20575.
To avoid an uncaught IntegrityError causing a 500 HTTP response in a
race between two processes trying to mute a topic, we catch the
integrity error and raise the error exception with status 400 we'd
have gotten if the second request had been a bit later.
Fixes#21011.
The S3 backend implementation of upload_emoji_image was accessing
emoji_file.name - which is redundant because emoji_file_name already

Fixes#20132.
EMAIL_HOST_USER without EMAIL_HOST_PASSWORD is not going to be a valid
configuration, and may result from making mistake in correctly setting
it in the secrets file and end up being a non-obvious cause of failure
to send email. Logging an error will be useful for detecting it. Further
conditions can be added to the function in the future.
Calling `get_apns_context` opens (and caches) an open connection to
the APNs servers. Since `apns_enabled` is called from Django
codepaths, this means that the Django processes hold unnecessary
connections open to the APNs servers.
Switch `apns_enabled` to checking what `get_apns_context` checks when
we're just returning True/False.

The new release adds the commit:
20ac22b96d
Which allows us to get rid of the entire ugly override that was needed
to do this commit's job in our code. What we do here in this commit:
* Use django-scim2 0.17.1
* Revert the relevant parts of f5a65846a8
* Adjust the expected error message in test_exception_details_not_revealed_to_client
since the message thrown by django-scim2 in this release is slightly
different.
We do not have to add anything to set EXPOSE_SCIM_EXCEPTIONS, since
django-scim2 uses False as the default, which is what we want - and we
have the aforementioned test verifying that indeed information doesn't
get revealed to the SCIM client.

Adds request as a parameter to json_success as a refactor towards
making `ignored_parameters_unsupported` functionality available
for all API endpoints.
Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.
As a preparatory step to refactoring json_success to accept
request as a parameter, change `do_report_error`, which is
called from the events queue for "error_reports", to return
None instead of json_success.
Adds an assertion error to `ErrorReporter` queue processor
and removes `JsonableError` from `do_report_error`.
It is likely that `do_error_report` was moved from a view in a
previous refactor, but was not updated to no longer return an
HttpReponse.
As a preparatory step to refactoring json_success to accept
request as a parameter, update helper function `compose_views`
in `views.streams.py` to return the response data and call
json_success from view functions that utilize `compose_views`.
Also, updates related test in `zerver.tests.test_subs.py`.
As a preparatory step to refactoring json_success to accept
request as a parameter, change interface of helper functions:
`handle_deferred_message` in `views.message_send.py` and
`mute_topic` and `unmute_topic` in `views.muting.py`, so
that they return None or data for json_success.
Instead call json_sucess in the caller function, which already
has the HttpRequest as a parameter.
Adds a check for `additionalProperties: true` when there are no
properties listed in the schema.
This currently only happens in one place, but will be helpful for
deduplicating text between the `register-queue` and `get-events`
endpoints.
Wordle has recently become a thing and it uses green, yellow and white (or
black in dark mode) large square unicode characters to let people share their
gameplay. Zulip converts the white and black large square unicode characters to
emojis, but not the green and yellow ones. This causes the Wordle grid to be
misaligned when shared on Zulip.
This commit adds green and yellow large square emojis to our emoji list to fix
the problem.
Previously, we only checked mandatory_topics setting before
sending message in frontend and there was no restriction in
backend. This commit adds the check in backend also making
sure messages without topic cannot be sent through API as
well if mandatory_topics setting is set to True.
Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.
We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.
Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.

There are three user settings that are integer enums:
`color_scheme`, `demote_inactive_streams` and
`desktop_icon_count_displays`.
Unlike the other user settings, these were using the `content`
keyword instead of the `schema` keyword in their definitions,
which caused them not to be rendered correctly in the api
documentation.
Changes the keyword to `schema` and fixes the indentation
for these three user settings in the two endpoints using
them.
Removes various instances of quotation marks that are not needed,
specifically looking at instances of arrays, e.g. `- "`, in the
OpenAPI documentation.
The target realm was not being passed to create_attachment in
upload_message_file implementations. This was a bug in the edge-case of
cross-realm messages - in particular, causing a bug in the email
gateway:
When an email with an attachment is sent, the message is mirrored to
Zulip with Email Gateway Bot as the message sender and uploader of the
attachment. Due to the realm not being passed to create_attachment, the
Attachment would get created with .realm being the system bot realm,
making the attachment inaccessible under some conditions due to failing
the following condition check (that's expected to pass, provided that
the .realm is set correctly):
```
if (
attachment.is_realm_public
and attachment.realm == user_profile.realm
and user_profile.can_access_public_streams()
):
# Any user in the realm can access realm-public files
return True
```
Fixes the rendering of enums to show strings with quotation marks,
while integers will continue to be rendered without quotation marks.
This allows for an empty string to be passed as an enum value and be
rendered as such in the documentation. Null will be rendered without
quotation marks, like integer values.
Makes `edit_timestamp` and `user_id` required fields for all
`update_message` events.
Adds `rendering_only` as another required field to signal if
events are only updating the rendered content of the message,
which is currently the case for adding inline url previews.
Updates `test_event.py` so that `do_update_message` and
`do_update_embedded_data` refer to the same testing schema
for `update_message` events, and therefore reflect the same
required fields for the `update_message` event.
The OpenAPI definition for `update_message` events is also
updated to reflect the required field and descriptions of
various properties are updated for the addition of the
`rendering_only` property.
Moves details about the rate limit error object and handling to
the OpenAPI documentation description for that common error.
Previously, this information was on the general rest error
handling documentation page without clear connection to the
specific rate limit error.
Fixes a typo in the changelog (feature 36) for that same error
and also fixes a misplaced colon in the description of the error
for missing request parameters.
Adds detailed definition of objects in the `subscription_data` parameter
array for the `/update-subscription-settings` endpoint.
Fixes#20825. Follow-up to #20409.
Formats and moves whether a field of an object in a request

The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.
This is a part of #20289.
do_make_stream_web_public and do_change_stream_invite_only seem
to contain very similar logic that could just live inside the
do_change_stream_permission function that handles all permission
changes in one place.

revoke_invites_generated_by_user should send invites_changed event if it
actually revokes some invitations. This is called in the user
deactivatoin codepath.
Event of type "realm_user", op "remove", emitted by do_deactivate_user
should remove the user id from subscriptions in the state. We weren't
catching this bug, because test_do_deactivate_bot uses a newly created
bot, so no stream subscriptions are affected. The bug shows up if
deactivating e.g. cordelia - thus we want to have two tests instead,
one for testing bot deactivation and one for user deactivation.
We now use recipient_id % 24 for new stream colors
when users have already used all 24 of our canned
colors.
This fix doesn't address the scenario that somebody
dislikes one of our current canned colors, so if a
user continually changes canned color N to some other
color for new streams, their new streams will continue
to include color N (and the user will still need to
change them).
This fix doesn't address the fact that it can be expensive
during bulk-add situations to query for all the colors
that users have already used up.

Leaving old invitations valid, potentially for a very long time, is

using the link they've created for themselves.
do_revoke_user_invite and do_revoke_multi_use_invite were using objects
after their deletion to pass the argument to notify_invites_changed. We
should avoid that. The function was only using the .realm attribute of
the received objects, so it's simpler to make it just take realm as its
argument.

An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.
Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.
This is a part of #20289.
Prior to this commit, we wrapped all incoming messages from Slack
in backticks. This led to weird formatting errors when an incom-
ing message from Slack contains backticks, to refer to a function
name, for instance.
Moves `flags` field to top part of object description because
it is always included in the event.
If a field is present only for certain types of message updates,
the description begins by stating when the field is present:
"Only present if ...".
These fields are organized by the type of message update:
stream, stream and/or topic, topic, content.
If a field is not present due to a special event, the description
ends by stating when the field is not present:
"Not present if ...".
Adds documentation for fields currently required to be returned
with any `update_message` event.
do_delete_users had two bugs:
1. Creating the replacement dummy users
with active=True
2. Creating the replacement dummy users with email domain set to
realm.uri, which may not be a valid email domain.
Prior commits fixed the bugs, and this migration fixes the pre-existing
objects.
Otherwise the dummy user can be created with an invalid email domain -
e.g. in development environment with the domain
"@http://localhost:9991". get_fake_email_domain exists exactly for
handling these kinds of scenarios.
Stop using `access_user_group_by_id` in notifications codepaths, as it
is meant to be used to check for _write_ access, not read
access (which is not limited). In the notification codepaths, there
are no ACLs to apply, and the ID is known-good; just load it
directly. The `for_mention` flag is removed, as it was not used in the
mention codepaths at all, only the notification ones.
get_remote_server_by_uuid (called in validate_api_key) raises
ValidationError when given an invalid UUID due to how Django handles
UUIDField. We don't want that exception and prefer the ordinary
DoesNotExist exception to be raised.
APNs payloads nest the zulip-custom data further than the top level,
as Android notifications do. This led to APNs data silently never
being truncated; this case was not caught in tests because the mocks
provided the wrong data for the APNs structure.
Adjust to look in the appropriate place within the APNs data, and
truncate that.
This replaces the temporary (and testless) fix in
24b1439e93 with a more permanent
fix.
Instead of checking if the user is a bot just before
sending the notifications, we now just don't enqueue
notifications for bots. This is done by sending a list
of bot IDs to the event_queue code, just like other
lists which are used for creating NotificationData objects.
Credit @andersk for the test code in `test_notification_data.py`.
As explained in the comments in the code, just doing UUID(string) and
catching ValueError is not enough, because the uuid library sometimes
tries to modify the string to convert it into a valid UUID:
>>> a = '18cedb98-5222-5f34-50a9-fc418e1ba972'
>>> uuid.UUID(a, version=4)
UUID('18cedb98-5222-4f34-90a9-fc418e1ba972')
This diff looks slightly noisy, but the main chunk of
code that we moved here has the same logic as before,
and it just gets realm_id from MentionBackend now, instead
of having our markdown processor have to supply it.
We basically want MentionData to be the gatekeeper of
mention data, and then we delegate backend tasks to
MentionBackend.
Soon we will add a cache to MentionBacked, which will
justify this change a bit more.
We now make it mandatory to pass in the Realm object.
If this function was ever called with None, I am scared
to know what the expected results were at the time of
writing.
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.
I tried to make the cache code relatively unobtrusive
for the single-message use case.
We should be able to eliminate redundant stream queries
using similar techniques.
I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.
When our handlers specifically reference self.md.zulip_db_data,
we now use an explicit type.
We probably want a more robust solution here, such as a semgrep
rule.
We now serialize still_url as None for non-animated emojis,
instead of omitting the field. The webapp does proper checks
for falsiness here. The mobile app does not yet use the field
(to my knowledge).
We bump the API version here. More discussion here:

We don't have to go to the database to get the Recipient
fields for `user_profile.recipient`.
See also 85ed6f332a from a little
over a year ago--it's very similar.
The bug here probably didn't come up too much in
practice, but if we were adding a user to multiple
streams when they already had used all N available
colors, all the new streams would be assigned the same
color, since the size of used_colors would stay at N,
thwarting our little modulo-len hackery.
It's not a terrible bug, since users can obviously
customize their stream colors as they see fit.
Usually when we are adding a user to multiple streams,
the users are fairly new, and thus don't have many
existing streams, so I have never heard this bug
reported in the field.
Anyway, assigning the colors in bulk seems to make more
sense, and I added some tests.
For the situations where all the colors have already
been used, I didn't put a ton of thought into exactly
which repeated colors we want to choose; instead, I
just ensure they're different modulo 24. It's possible
that we should just have more than 24 canned colors, or
we should just assign the same default color every time
and let users change it themselves (once they've gone
beyond the 24, to be clear). Or maybe we can just do
something smarter here. I don't have enough time for a
deep dive on this issue.
Part of our codepath for subscribing users involves
fetching the users' existing subscriptions to make sure
we can do things like properly report to the clients
that the users were already subscribed. This codepath
used to be coupled to code that helped users maintain
unique stream colors.
Suppose you are creating a new stream, and you are
importing users from an older stream with 15k
subscribers, and each of your users is subscribed to
about 20 streams.
The prior code, instead of filtering on recipient_id,
would literally look at every subscription for every
user, which was kind of crazy if you didn't understand
the pick-stream-color complications.
Before this commit, we would fetch 300k rows with 15
columns each (granted, all but one of the columns are
bool/int). That's a total of 4.5 million tiny objects
that we had to glom into Django ORM objects and slice
and dice.
After this commit, we would fetch exactly zero rows
for the are-they-already-subscribed logic.
Yes, ZERO.
If we were to mistakenly try to re-add the same 15k
subscribers to the new stream (under the new code), we
will now fetch 15k Sub rows instead of 300k.
It is worth looking at the prior commit. We go through
great pains to ensure that users get new stream colors
when we invite them to a stream, and we still fetch a
bunch of data for that. Instead of 4.5 million cells,
it's more like 600k cells (2 columns per row), and it's
less than that insofar as some users may only
have 24 distinct colors among their many streams.
It's a lot of work.
This commit sets us up for the next commit, which will
save us a very expensive query.
If you are adding 15k users to a stream, and each user
has about 20 existing streams, then we need to retrieve
300k rows from the database to figure out which stream
colors they already have. We don't need all the extra
fields from Subscription, so now we get just the two
values we need for making a color map.
In the next commit we'll eliminate the other use case
for the big query, and I will explain in greater
depth how splitting out the color-picking code can
be a huge win. It is possible that some product decisions
could make this codepath easier. We could also do some
engineering specific to stream colors, such as caching
which colors users have already used.
This does cost us an extra round trip to the database.
Having the `wildcard_mentions_notify` setting turned on does
not necessarily mean that the user will receive notification
for that message. There is more nuance to this, as explained
in the updated comment.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.
With some changes by Tim Abbott.
Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.
This requires modifying some tests to use valid uuids.
We avoid repeating the same calculations over and
over again for the same stream.
This helps, but the real bottleneck in this function
is that send_event usually takes at least a millisecond,
and that adds up quickly if you're doing something
like subscribing 5k users to a new stream.
