If the server controls the registration's hostname, it can reclaim its
registration credentials. This is useful, because self-hosted admins
frequently lose the credentials when moving their Zulip server to a
different machine / deployment method.
The flow is the following:
1. The host sends a POST request to /register specifying
registration_takeover=true.
2. The bouncer responds with a signed token.
3. The host prepares to serve this token at /zulip-services/verify and
sends a POST to /remotes/server/register/verify_challenge endpoint of
the bouncer.
4. Upon receiving the POST request, the bouncer GETS
https://{hostname}/zulip-services/verify,
verifies the secret and responds to the original POST with the
registration credentials.
5. The host can now save these credentials to it zulip-secrets.conf file
and thus regains its push notifications registration.
Python parameter defaults are only evaluated once at the function
definition site, not at each call site. So these defaults were
incorrectly evaluating to the server’s startup time rather than the
current time.

* confirm_email_change
* handle_upload_pre_finish_hook
* deliver_scheduled_emails

* upload_message_attachment
* register_remote_server
* do_soft_deactivate_users

It helps to avoid creating unintended savepoints in the future.
This is as a part of our plan to explicitly mark all the
transaction.atomic calls with either 'savepoint=False' or
'durable=True' as required.
* 'savepoint=True' is used in special cases.
This commit adds 'durable=True' to the outermost transaction
in 'remote_server_post_analytics'.
It also adds 'savepoint=False' to inner transaction.atomic
decorator to avoid creating savepoint.

transaction.atomic decorators with either 'savepoint=False' or

This commit adds 'durable=True' to the outermost transactions

We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
Reorders audit log string methods to have the following pattern:
"event_type event_time (id): modified_object". And the event type
is the name for the AuditLogEventType enum.
Created using manage.py squashmigrations with a couple changes:
- Patched Django to optimize AddConstraints/RemoveConstraints properly.
- Used the StateOperations from the
migrations.SeparateDatabaseAndState section in migration 0060, so
that the constraint changes could be optimized properly.
- Removed dependencies on zerver, since this project does not actually
have any dependencies on zerver migrations.
We plan to remove the 'tutorial_status' field from UserProfile
table as it is no longer used to show tutorial.
The field is also used to narrow a new user in DM with
welcome bot on the first load.
This prep commit updates the logic to use a new OnboardingStep
for the narrowing behaviour on the first load. This will help
in removing the 'tutorial_status' field.
Because Django does not support returning the inserted row-ids with a
`bulk_create(..., ignore_conflicts=True)`, we previously counted the
total rows before and after insertion. This is rather inefficient,
and can lead to database contention when many servers are reporting
statistics at once.
Switch to reaching into the private `_insert` method, which does
support what we need. While relying a private method is poor form, it
is mildly preferable to attempting to re-implement all of the
complexities of it.
Instead of the PUSH_NOTIFICATIONS_BOUNCER_URL and
SUBMIT_USAGE_STATISTICS settings, we want servers to configure
individual ZULIP_SERVICE_* settings, while maintaining backward
compatibility with the old settings. Thus, if all the new
ZULIP_SERVICE_* are at their default False value, but the legacy
settings are activated, they need to be translated in computed_settings
to the modern way.
This commit renames the "Huddle" Django model class to
"DirectMessageGroup", while maintaining the same table --
"zerver_huddle".
Fixes part of #28640.
This commit performs a sweep on the first batch of non API
files to rename "huddle" to "direct_message_group`.
It also renames variables and methods of type -
"huddle_message" to "group_direct_message".
This is a part of #28640
This is done in as much of a drop-in fashion as possible. Note that
libvips does not support animated PNGs[^1], and as such this
conversion removes support for them as emoji; however, libvips
includes support for webp images, which future commits will take
advantage of.
This removes the MAX_EMOJI_GIF_SIZE limit, since that existed to work
around bugs in Pillow. MAX_EMOJI_GIF_FILE_SIZE_BYTES is fixed to
actually be 128KiB (not 128MiB, as it actually was), and is counted
_after_ resizing, since the point is to limit the amount of data
transfer to clients.

Earlier `num_before` and `num_after` wasn't being passed while
testing.
Moving to typed_endpoint requires all the "required" parameters
to be passed to the function explicitly in tests.
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`

This helps prevent wraparound on exceedingly large and old installs,
particularly Zulip Cloud. These are relatively simple migrations
since they are not referenced by any other tables; however, they are
quite large, and are actively used from Django by running servers,
making this not a migration which is possible to run without stopping
the server.
Use the escape hatch in the previous commit to temporarily pause
analytics writes while the migration happens. This should make the
migration transparent to users, at the small cost of an artificial dip
in statistics (specifically, to push notification counts, and unread
message counts) while the migration runs.
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 is a follow-up to #29425. It assigns creator to three streams
that are used in tests and another two that aren't. For tests,
we assign a guest, an admin and an owner as creator.
