The definition of the "subscription" parameter didn't include full
information about the parameter. It only said that an array of objects
is passed as a parameter, and relied on description of the parameter
to explain what the object contained. I edited the definition to contain
the full information about the object.
Fixes#20824.
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.
queue_client.queues does not list all the queues that exist on the
server (you can’t do that over AMQP); the condition "test_suite" in
queue_client.queues was always false. So the test_suite queue could
accumulate extra messages that broke test_queue_error_json.

Adds a check for object in parameter type that will render the details

definition in the OpenAPI documentation.
Fixes#19424.
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.
See https://chat.zulip.org/#narrow/stream/3-backend/topic/assigning.20stream.20colors

The limit here is purely to prevent breakage in case of a pathological
number of images in a single message; 5 images is entirely possible in
a reasonable message, and causes user confusion when they are not
expended.

oneOf with two identical branches (modulo example) is a bug because
oneOf means exclusive or. It’s also a totally inappropriate kludge
for encoding multiple examples. The OpenAPI specification provides a
perfectly good standard way to do that:

However, we don’t handle that in our OpenAPI documentation generator

Although allOf is often used to indicate inheritance, its semantics
are that of a plain set intersection. The intersection of a nullable
property with a non-nullable property is a non-nullable property.
Therefore, if we want an inherited property to remain nullable, we

The subscriber list was not updating without a refresh on
reactivating user, because the subscriptions data with the
client was not updated on reactivation.
This commit adds code to send peer_add subscription events
on reactivating the user.
We do not send peer_remove events on deactivating the user,
but the subscriber list is still live-updated because we
have the data of the streams which the deactivated user is
susbcribed to and the clients itself updates the data and UI
on receiving event of deactivation of user, which it is not
possible when reactivating the user.
Fixes#20383.
Leaving old invitations valid, potentially for a very long time, is
clearly unexpected and undesired behavior under normal circumstances. A
user shouldn't be able to e.g. generate a multiuse invite link, get
banned from the organization by being deactivated and then just re-join
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.
The msg parameter is a string to be displayed when the expected
exception wasn’t raised, not a pattern to match against the raised
exception’s message.

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:

Fixes#18569.
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.
GIF files can be `.GIF`, and also we determine the file format by
inspecting the image data, so there's no reason to have this
assertion.
(The code for serving still images does not rely on the file being a
GIF.)
Have kept process_new_human_user out of
the atomic block because it involves many
different operations and also sends events.
Tried enclosing event in on_commit but that
would need many changes in the tests, so have
skipped it for now.
Updates testing helpers in `event_schema.py` for `do_update_message` so
that all stream message fields are present in any edits / updates to
stream messages. Adds verfication tests of events returned from private
message edits and from stream message content-only and topic-only edits.
Updates the `update_message` event type to always include a `stream_id`
field when the message being edited is a stream message. This change
aligns with the current definition of the `\get-events` endpoint
in the OpenAPI documentation.
It is better to press on, than stop halfway through due to a user
whose email no longer works. The exception is already logged, which
is sufficient here, as this is generally run interactively.
These fundamentally tested send_email, not build_email, and thus
belong in TestSendEmail, not TestBuildEmail. They also duplicated the
code in test_send_email_exceptions; reuse it.
This allows verify_uploads to use the database
as the authoritative source for what attachments
we need to look for when we're verifying the
images got exported properly, while still
also verifying attachment.json is correct.
It is better for the verifying code to just explicitly
ensure that the exported file bytes match the bytes
in the test image. This introduces a tiny bit more
of I/O.
It's easier to read the code without the intermediate
full_data dictionary that obscures where the files live.
We also avoid some unnecessary file i/o in the tests.
We do a sanity check for every table
that gets written to user.json as part of
the single-user export.
If we add more tables to the single-user export,
the test that I modified here will now ask
the author to add a new checker function, which
means we should always have at least a basic
sanity check for every exported table as long
as we stay in this new paradigm.
We also remove a little bit of old code that
became redundant.
