Multiple events may be created with the same timestamp; we add a
default ordering by "id" such that these have a consistent ordering in
tests (to solve for flaky tests), as well as in the internal API.
This commit removes create_private_stream_policy setting as
we now use new group based setting.
The "/register" response includes realm_create_private_stream_policy
field to return a value representing superset of users who have the
permission to create private channels, as older clients still expect
this field.
This commit helps in using the realm object which has the
prefetched group settings so that we can avoid extra queries
when calculating fields like can_create_public_streams.
There is no need to prefetch group settings using select_related
in get_realm as we only need to save queries when computing the
setting values in fetch_initial_state_data and we already refetch
the realm using get_realm_with_settings for that.
This commit updates code to prefetch realm group settings like
"can_create_public_channel_group" only when computing settings
for "/register" response by refetching the realm object with
select_related instead of fetching those settings in UserProfile
query.
This change is done because we do not need to prefetch these
settings for every UserProfile object and for most of the cases
where these settings are actually accessed, we can afford extra
query like when checking permission to create streams. But we
cannot afford one query extra for each setting when computing
these settings for "/register" response, so we re-fetch the
realm object with select_related leading to only one extra
query.
The query count changes in tests are -
- Query count increases by 1 when calling fetch_initial_state_data
for computing can_create_public_streams because Realm object from
UserProfile does not have prefetched setting fields.
- Query count increases by one in test_subs where streams are
created which is as expected due to the setting not being prefetched.
- Query count increases by 2 in tests in test_home.py where one
query is to refetch the realm object and one for computing
can_create_public_streams as mentioned above.
This commit removes create_public_stream_policy setting
since public channel creation permissions are now handled
by group-based setting.
We still pass "realm_create_public_stream_policy" in
"/register" response though for older clients with its
value being set depending on the value of group based
setting. If we cannot set its value to an appropriate
enum corresponding to the group setting, then we set
it to "Members only" considering that server will not
allow the users without permissions to create public
channels but the client can make sure that UI is
available to the users who have permission.
Migrate all `ids` of anything which does not have a foreign key from
the Message or UserMessage table (and would thus require walking
those) to be `bigint`. This is done by removing explicit
`BigAutoField`s, trading them for explicit `AutoField`s on the tables
to not be migrated, while updating `DEFAULT_AUTO_FIELD` to the new
default.
In general, the tables adjusted in this commit are small tables -- at
least compared to Messages and UserMessages.
Many-to-many tables without their own model class are adjusted by a
custom Operation, since they do not automatically pick up migrations
when `DEFAULT_AUTO_FIELD` changes[^1].
Note that this does multiple scans over tables to update foreign
keys[^2]. Large installs may wish to hand-optimize this using the
output of `./manage.py sqlmigrate` to join multiple `ALTER TABLE`
statements into one, to speed up the migration. This is unfortunately
not possible to do generically, as constraint names may differ between
installations.
This leaves the following primary keys as non-`bigint`:
- `auth_group.id`
- `auth_group_permissions.id`
- `auth_permission.id`
- `django_content_type.id`
- `django_migrations.id`
- `otp_static_staticdevice.id`
- `otp_static_statictoken.id`
- `otp_totp_totpdevice.id`
- `two_factor_phonedevice.id`
- `zerver_archivedmessage.id`
- `zerver_client.id`
- `zerver_message.id`
- `zerver_realm.id`
- `zerver_recipient.id`
- `zerver_userprofile.id`

These models have no external references, and are among the larger
tables. Migrate them to bigints, starting with `useractivityinterval`
which is less likely to be being touched.
This index is used by `active_users_audit:is_bot:day`, and provides
roughly a 2x speedup. The existing
`zerver_realmauditlog_realm__event_type__event_time` is used if there
is a realm limit, but the standard statistics fill runs for all realms
at once, and thus cannot use it.
Migration plan:
1. Add NULLable .last_update_id column to UserPresence with default 0
for new objects.
2. Backfill the value to 0 for old UserPresences, can be done in the
background while server is running.
3. Make the column non-NULL.
4. Add new model PresenceSequence and create its rows for old realms.
Previously, when the operand of id operator was more than
2147483647, it was raising server error. This is because the
maximum permissible PostgreSQL integers value is 2147483647.
This is fixed by raising a BadNarrowOperatorError in case the
id operand is larger than 2147483647.
Removes the 'onboarding_steps' field on 'UserProfile'
model which is no longer used.
It was introduced back in 2013 (b5e22bf), and is no
longer used.
Fixes part of #30043.
This commit updates code, majorly in tests, to use
setting values from enums instead of directly using
the constants defined in Realm.
We still have those constants defined Realm as they
are used in a couple of places where the same code
is used for different settings. These will be
handled later.
This commit adds include_realm_default_subscriptions parameter
to the invite endpoints and the corresponding field in
PreregistrationUser and MultiuseInvite objects. This field will
be used to subscribe the new users to the default streams at the
time of account creation and not to the streams that were default
when sending the invite.
Mark the channel name of the initial channel created during
realm creation for translation.
It doesn't mark the topic names and description for translation
because we are planning to remove these topics and update the
description as a part of improving the onboarding experience.
We no longer create the 'core team' private channel when
a realm is created.
Earlier, "New user announcements" channel was set to the
"core team" channel. Now it is disabled by default.
populate_db still creates the 'core team' channel to
represent a private channel.
Fixes#29632.
The issue description explains this well:
We currently recalculate `currently_used_upload_space_bytes` every file
upload, by dint of calling `flush_used_upload_space_cache` on
save/delete, and then immediately calling
`user_profile.realm.currently_used_upload_space_bytes()` in
`notify_attachment_update`. Since this walks the Attachments table,
recalculating this can take seconds in large realms.
Switch this to using a CountStat, so we don't need to walk significant
chunks of the Attachment table when we upload an attachment. This will
also give us a historical daily graph of usage.
In #23380, we are changing all occurrences of uri with url in order to
follow the latest URL standard. Previous PRs #25038 and #25045 has
replaced the occurences of uri that has no direct relation with realm.
This commit changes just the model property, which has no API
compatibility concerns.
The "invites" worker exists to do two things -- make a Confirmation
object, and send the outgoing email. Making the Confirmation object
in a background process from where the PreregistrationUser is created
temporarily leaves the PreregistrationUser in invalid state, and
results in 500's, and the user not immediately seeing the sent
invitation. That the "invites" worker also wants to create the
Confirmation object means that "resending" an invite invalidates the
URL in the previous email, which can be confusing to the user.
Moving the Confirmation creation to the same transaction solves both
of these issues, and leaves the "invites" worker with nothing to do
but send the email; as such, we remove it entirely, and use the
existing "email_senders" worker to send the invites. The volume of
invites is small enough that this will not affect other uses of that
worker.

This commit removes name, description, is_system_group and
can_mention_group fields from UserGroup model and rename
them in NamedUserGroup model.
Fixes#29554.
This commit updates code to access name from named_user_group
field which points to the "NamedUserGroup" instead of directly
accessing name from "UserGroup", since name field will only
be present on NamedUserGroup objects in further commits.
In zerver/models/streams.py, updates translated string for when everyone
can post to a stream/channel to use channel instead of stream.
Part of stream to channel rename project.
In zerver/models/realms.py, updates the topic for stream/channel updates
to be "channel events" instead of "stream events".
Part of stream to channel rename project.
Adds nullable creator field, containing a reference to the user who
created the stream. When creating a stream, acting user is set as
the creator of the stream. Since API calls to create streams always
have an acting user, this field should always be set when streams
are created using the API.
Because streams can be created with no acting user, this field is
nullable. We try to backfill existing streams using RealmAuditLog table,
but not all streams are guaranteed to have a recorded create log. Thus
this new field is left null when it cannot be backfilled. We also set
this field to null when the creator user is deleted.
Adds an index on RealmAuditLog for the realm, event_type, and
event_time in order to improve database queries on these audit logs.
tabbott verified using EXPLAIN ANALYZE that this also considerably
speeds up queries that order by ID rather than event_time, but
event_time is how these should be ordered given the possibility of
backfills.
This commit adds an option to the advanced section of
Preferences settings, that would allow users to choose
whether to receive typing notifications from other
users.
Fixes#29642
For simiplicty's sake, we can avoid trying to do cache invalidation in
the variety of events that can cause the seat count to change - since
having an up to 1 day delay between users being added and the upload
limit going up is quite reasonable.
