Fixes#20028.
There's no reason to have a special `RealmCreationKey` class - the
`Confirmation` system already does this job.
This is somewhat complicated by the need to write a migration for
`RealmCreationKey`->`Confirmation` for pre-existing, valid objects, to
avoid breaking realm creation links that haven't been used yet.
Generated using the squashmigrations tool, with:
- A tiny Django patch to avoid special handling of the temporary
EmailChangeStatus proxy model.
- Switching AddIndexConcurrently to AddIndex to help squashing. This
may not have been necessary.
Migration 0015 was not squashed because of its dependency on newer
zerver migrations.
Without this, Django builds queries with which compare tables' "id"
fields to `("confirmation_confirmation"."object_id")::bigint`; the
explicit cast prevents the index added in the previous commit from
being used.
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`

Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

The database value for expiry_date is None for the invite
that will never expire and the clients send -1 as value
in the API similar to the message retention setting.
Also, when passing invite_expire_in_days as an argument
in various functions, invite_expire_in_days is passed as
-1 for "Never expires" option since invite_expire_in_days
is an optional argument in some functions and thus we cannot
pass "None" value.
With the previous steps, all Confirmation objects should have been
migrated and the expiry_date field is being used for checking
confirmation validity - so all that's left is to set the NOT NULL
constraint on the column.
The commit:
1. Adds the new field as nullable.
2. Adds code that'll create new Confirmation with the field set
correctly.
3. For verifying validity of Confirmation object this still uses the old
logic in get_object_from_key() to keep things functioning until we
backfill the old objects in the next step.
Thus this commit is deployable. Next we'll have a commit to run a
backfill migration.
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.

Apparently, we didn't have any database indexes on Confirmation, which
meant that on servers with large numbers of users like zulipchat.com,
new account registration could spend a ton of time effectively doing a
table scan on this table.
Also adds Confirmation.type, and cleans up the rest of Confirmation to look
more like the model definitions in zerver.
In the migration, all existing confirmations adopt the type
USER_REGISTRATION, to be conservative. In a few commits, different
confirmation types will have different validity periods, and
USER_REGISTRATION will have the shortest default.
This adds to Zulip support for a user changing their own email
address.
It's backed by a huge amount of work by Steve Howell on making email
changes actually work from a UI perspective.
Fixes#734.
This commit loses some indexes, unique constraints etc. that were
manually added by the old migrations. I plan to add them to a new
migration in a subsequent commit.
