We add a new wildcard_mention_policy setting to handle wildcard
mentions in large streams, with a wide range of policies available to
organizations.
We set the default to the safe option for preventing accidental spam:
only stream administrators being able to use wildcard mentions in
large streams.
There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

The query to finds and marks all unread UserMessages in the stream as read
can be quite expensive, so we'll move that work to the deferred_work
queue and split it into batches.
Fixes#15770.
This function now matches the copy in zerver/lib/actions.py.
This is the same migration as
b250e42f61c525029bd2b3bbb8f4ea93ece62072; orjson enforces that we
don't use integers as keys in JSON dictionaries.
This commit adds the is_web_public field in the AbstractAttachment
class. This is useful when validating user access to the attachment,
as otherwise we would have to make a query in the db to check if
that attachment was sent in a message in a web-public stream or not.
This commit adds role field to the Subscription class. Currently,
there are two option of roles - STREAM_ADMINISTRATOR and MEMBER.
We also add a property 'is_stream_admin' for checking whether the
user is stream admin or not.
In f8bcf39014, we fixed buggy
marshalling of Streams and similar data structures where we were
including the Stream object rather than its ID in dictionaries passed
to ujson, and ujson happily wrote that large object dump into the
RealmAuditLog.extra_data field.
This commit includes a migration to fix those corrupted RealmAuditLog
entries, and because the migration loop is the same, also fixes the
format of similar RealmAuditLog entries to be in a more natural format
that doesn't weirdly nest and duplicate the "property" field.
Fixes#16066.
Also add a Draft object-to-dictionary conversion method.
The following commits will provide an API around this
model using which our clients can sync drafts across each
other (if they so wish too). As of making this commit, we
haven't finalized exactly how our clients will use this.
See https://chat.zulip.org/#narrow/stream/2-general/topic/drafts
For some of the discussion around this model and in general,
around this feature.

A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
To be more consistent with the meaning in the Stream model, and to make
it easier to have a reasonable settings API, we get rid of the None
value for Realm.message_retention_days in favor of the value -1 to
represent the "don't delete messages" default policy.
Migrations that add items to a table in the same migration htat

With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.

Attachment objects in production are only created in one place, which
passses a size. Additionally, I verified in multiple production
environments with old data that this never actually happens (or has
happened).
So we should make the data model correctly reflect the possibilities here.
This fixes a missing unique constraint on the Reactions data model
state when using multiple aliases for an emoji code. As with any
missing unique constraints, we first need to apply a migration that
eliminates violations of the rule; in this case, deleting the
duplicates is correct.
Added unique constraint for "user_profile", "message",
"reaction_type", "emoji_code".
Fixes#15347.
This migration fixes any PreregistrationUser objects that might have
been already corrupted to have the administrator role by the buggy
original version of migration 0198_preregistrationuser_invited_as.
Since invitations that create new users as administrators are rare, it
is cleaner to just remove the role from all PreregistrationUser
objects than to filter for just those older invitation objects that
could have been corrupted by the original migration.
This migration incorrectly swapped the role associated with invitation
objects between members and organization administrators, resulting in
most invitation objects that existed before the upgrade to Zulip
2.0.0-rc1 or later to be incorrectly administrator invitations.
Fixing the migration is safe and will help those installations
upgrading directly from 1.9.x to 2.1.5 or later.
A migration to fix the corrupted records will appear in an upcoming
commit.
Google has removed the Google Hangouts brand, thus we are removing
them as video chat provider option.
This commit removes Google Hangouts integration and make a migration
that sets all realms that are using Hangouts as their video chat
provider to the default, jitsi.
With changes by tabbott to improve the overall video call documentation.
Fixes: #15298.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
in the form of POST request.
Includes a mixin test class that'll be useful for testing
Native auth flow.
Thanks to Mateusz Mandera for the idea of using redis and
other important work on this.

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.

mock is just a backport of the standard library’s unittest.mock now.
The SAMLAuthBackendTest change is needed because
MagicMock.call_args.args wasn’t introduced until Python
3.8 (https://bugs.python.org/issue21269).
The PROVISION_VERSION bump is skipped because mock is still an
indirect dev requirement via moto.

For privacy-minded folks who don't want to leak the
information of whether they're online, this adds an
option to disable sending presence updates to other
users.
The new settings lies in the "Other notification
settings" section of the "Notification settings"
page, under a "Presence" subheading.
Closes#14798.
Our previous set of indexes for the Message table did not contain
anything to optimize queries for all the messages in a topic in an
organization where the same topic name might appear in 10,000s of
messages in many streams.
We add two indexes here to support common queries
* A `(recipient_id, upper(subject), id)` index to support
"Fetch all messages from a topic" queries.
* A `(recipient_id, subject, id)` index to support
"Fetch all messages by topic"
We use the `DESC NULLS last` on both indexes because we almost always
want to query from the "Latest N messages" on a topic, not the
"Earliest N messages".
These indexes dramatically improve the performance of fetching topic
history (which remains not good enough in my opinion; we'll likely
need caching to make it nice), and more importantly make it possible
to check quickly which users have sent messages to a topic for the
"Topics I follow" feature.
Fixes part of #13726.
