This commit renames the realm-level setting 'notifications_stream'
to 'new_stream_announcements_stream'.
The new name reflects better what the setting does.
The presence of the name "François" in the random first name list led
to email addresses of the form `françois1234@zulip.com` which are
invalid.
Strip invalid ASCII from the email addresses generated in populate_db,
and validate them before tossing them verbatim into the database.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
In cloud:
Sponsored organizations have plan_type=STANDARD_FREE, don't have
a CustomerPlan object and thus no tier value.
With self-hosting:
Sponsored organizations have a CustomerPlan object with tier
TIER_SELF_HOSTED_COMMUNITY and a plan_type of PLAN_TYPE_COMMUNITY.
As of c9b0602320 and
8b55d60f9e we create a default
registration for the dev env "RemoteZulipServer" (and also RemoteRealms
for the dev realms) in populate_db. However these models weren't listed
in clear_database, meaning the state wasn't properly cleaned up at the
start of the command.
Most important, this would manifest in getting:
```
django.db.utils.IntegrityError: duplicate key value violates unique
constraint "zilencer_remotezulipserver_uuid_key"
DETAIL: Key (uuid)=(......) already exists
```
if you re-run populate_db.
This creates a valid registration, for two reasons:
1. Avoid the need to run "manage.py register_server" in dev env to
register, when wanting to to test stuff with
`PUSH_NOTIFICATION_BOUNCER_URL = "http://localhost:9991"`.
2. Avoid breaking RemoteRealm syncing, due to duplicate registrations
(first set of registrations that gets set up with the dummy
RemoteZulipServer in populate_db, and the second that gets set up via
the regular syncing mechanism with the new RemoteZulipServer created
during register_server).
Also adds `SWITCH_PLAN_TIER_AT_PLAN_END` for `CustomerPlan`
which will be used to mark status of remote server legacy
plans which are scheduled for an upgrade.
This default setup will be more realistic, matching the ordinary
conditions for a modern server.
Especially needed as we add bouncer code that will expect to have
RemoteRealm entries for realm_uuid values for which it receives
requests.
Moves and generalizes `switch_realm_from_standard_to_plus_plan`
in stripe.py to be a more general function for changing a
CustomerPlan to a new and valid tier, `do_change_plan_to_new_tier`.
Adds a helper function with the previous function name to be used
for the support view and management command for changing a realm
from the Standard plan tier to the Plus plan tier.
So that all child classes of BillingSession generate the same data
structure for customers that are created in Stripe, revise
`get_data_for_stripe_customer` to return a specific dataclass:
StripeCustomerData.
So that `update_or_create_stripe_customer` can work for Customer
objects with either a realm or remote_server, we create an abstract
base class, BillingSession, and implement a child class for the
current implementation of Customer objects with a realm.
Refactoring `update_or_create_stripe_customer` also moves
`create_stripe_customer` and `replace_payment_method` to the
BillingSession class.
