The previous implementation using Django's `get_or_create` for
`do_increment_logging_stat` involved two separate database queries,
potentially leading to race conditions.
Use an `ON CONFLICT ... DO UPDATE` (aka "upsert") query, which
eliminates race conditions and improves performance. This is mildly
complicated due to the different unique indexes across the various
tables, and the need for bug-for-bug compatibility with the previous
implementation.
Fixes#28947.

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.
Fixes: #21306Fixes: #24275
This prevents users from hammering the invitation endpoint, causing
races, and inviting more users than they should otherwise be allowed
to.
Doing this requires that we not raise InvitationError when we have
partially succeeded; that behaviour is left to the one callsite of
do_invite_users.

Gitter broke their older API as part of being integrated
into Matrix.
Their announcement blog says:
"Anything left using the Gitter APIs will need to be
updated to use the Matrix API"
This commit drops the legacy Gitter import tool and
we plan to build a new one for Matrix in future.
Updates the base hash for the streams setting overlay to be
"channels" instead of "streams".
Because there are Welcome Bot and Notification Bot messages that
would have been sent with the "/#streams" hash, we will need to
support parsing those overlay hashes as an alias for "/#channels"
permanently.
Part of the stream to channels rename project.
We now "first_message_id" of the stream on the deletion of the first
message that was sent to it. This results in 1 extra query when any
stream message is deleted and 3 extra queries when the first message
sent to any stream is deleted.
Fixes#28877.
Creates an IncompatibleParametersError to be used in cases where
there are two (or more) optional parameters for an endpoint that
are incompatible with each other, e.g. there's a parameter for a
user name and a user ID but only one should be sent in the request
to identify the user.
Documents the error on the /api/rest-error-handling article.
Updates the PATCH users/me/subscriptions/muted_topics endpoint to
use this error when both the stream and stream_id parameters are
passed (note this endpoint is currently deprecated).
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.
This commit adds get_recursive_strict_subgroups function
which returns all the subgroups but not includes the user
group passed to the function.
We also update the test to check subgroups of named user
groups using the get_recursive_strict_subgroups function.
This is fine as we already test the get_recursive_subgroups
function.
Earlier, we didn't soft-reactivate users for group mentions
at all because it wasn't easy to calculate group size.
Now, we will soft reactivate if the user group mentions has
less than 12 members.
We don't reactivate all users because a user group can have a
very large size, which can lead to large backlogs in the
deferred-work queue.
Fixes part of #27586.
Updates various areas of the backend code that generate
JsonableErrors with translated strings to use channel
instead of stream.
Part of stream to channel rename project.
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.
Updates the translated strings in the messages sent by the welcome
bot in new Zulip organizations to use channel instead of stream.
Comments out part of a test that uses translated Italian strings
to check these welcome bot messages and adds a TODO comment to
note that the test code should be uncommented when those strings
are translated for the stream -> channel rename.
Part of stream to channel rename project.
In zerver/lib/exceptions.py, updates translated error strings
to use channel instead of stream.
Note that the STREAM_WILDCARD_MENTION_NOT_ALLOWED and the
STREAM_DOES_NOT_EXIST error codes, and any additional fields
included with those errors, are not changed in these updates.
Part of stream to channel rename project.
Updates notification messages that are sent to "stream events"
topic when a permission or policy setting is changed to use channel
instead of stream. Also, updates some strings that were not marked
for translation in the message that was sent when the retention
policy was changed.
Updates notification messages that are sent when a stream/channel
is created.
Updates notification messages that are sent when a user is
subscribed to stream/channel(s).
Part of stream to channel rename project.
Updates translated JsonableError strings that relate to streams
to use channel instead of stream. Separated from other error string
updates as this is a dense area of changes for this rename.
Part of stream to channel rename project.
In zerver/actions/message_send.py, updates translated error strings
to use channel instead of stream.
Also, updates the messages sent to bot owners when a stream doesn't
exist or has no subscribers.
Part of stream to channel rename project.
Updates the translated "New streams" string in the email digest to
instead by "New channels". Also, marks that for translation in the
plain text version of the email.
Updates the generated stream/channel url to use stream_narrow_url
in preparation for updating stream narrow urls for the rename.
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.
Fixes#28403
Uses redis to remember the last time push notifications were experienced
working. This needs to work across processes, so can't be done just in
memory.
As this is transient data that's fairly harmless to lose and thus
doesn't require the persistence benefits of the database, and we're
keeping a single "row", so don't need an entire new db table, we settle
on using redis instead of postgres. This is also consistent with how we
store other kinds of such transient data.
Earlier a extra audit log entry of type
USER_GROUP_GROUP_BASED_SETTING_CHANGED was made when a new user
group is created. This commit updates the code to not create
that audit log entry.
There is no need to create these entry as we would still
have the required data from the "OLD_VALUE" field in the
audit log entry created when changing the setting and this
also makes it consistent with the entries created for
other operations like stream creation.
This timeout strategy using asynchronous exceptions has a number of
safety caveats (read the docstring!!) and should only be used in very
specific circumstances.

zerver.lib.timeout abuses asynchronous exceptions, so it’s only safe
to use on CPU computations with no side effects.
