Eeshan Garg 0b5324f345 corporate: Add helper for deactivating remote server registrations. 2022-01-03 14:02:48 -08:00
Mateusz Mandera c5c3ab66d6 remote_server: Migrate RemoteZulipServer.uuid to be UUIDField.
Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.

This requires modifying some tests to use valid uuids.

Eeshan Garg 79e9ba13e2 billing: Add do_change_remote_server_plan_type.
This is a part of the plumbing we need to support billing for
self-hosted customers.

Eeshan Garg 2cdaae681d actions: Rename do_change_plan_type -> do change_realm_plan_type.
We will soon be adding an equivalent function for RemoteZulipServer,
so it makes sense to rename this function to be more descriptive.

Eeshan Garg 7c9f587563 billing: Stop using UserProfile.delivery_email in Stripe handler.
Now that we pass in the UserProfile.id in the metadata to Stripe's
PaymentIntent objects, we no longer need to retrieve the user via
delivery_email. It makes more sense to just fetch the user by ID
and then get the latest delivery_email directly.

Note that an update to Stripe's fixtures is not necessary here
since a previous commit already modified the metadata passed to
both stripe.Session/PaymentIntent objects.

Eeshan Garg 88fd399bec billing: Use UserProfile.id to ascertain customer's email.
Previously, our Stripe webhook event handler code retrieved the
user's email from Stripe using the stripe.Customer.email attribute.
This led to situations such that whenever the email that Stripe had
did not correspond to a UserProfile in Zulip, the payment flow
failed since we couldn't find a UserProfile associated with the
given email.

Now, we pass in the UserProfile.id in the metadata to Stripe's
checkout Session object, so that we can fetch the correct email
in future Stripe requests.

Eeshan Garg b325a4f1be realm: Rename plan type constants to be more descriptive.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.

Eeshan Garg a808f02a22 billing/sponsorship: Allow blank organization URLs.
We ran into a bug in production caused by two issues:
- Some users came from orgs that didn't have a website and since
  the URL field was required, they submitted invalid URLs.
- We didn't properly respond to invalid form submissions, which
  led to UnboundLocalError exceptions in another part of the
  code.

This commit solves this by doing the following:
- We now allow blank URLs and have a convenient placeholder text
  label that tells users that they may leave the URL field blank.
- This commit refactors the code such that invalid form submissions
  result in an informative error message about what exactly went
  wrong.

Vishnu KS 158cec84ec stripe: Upgrade stripe API to 2020-08-27 version.
This upgrades the Stripe API to the most recent version. Going through
the Git history, it looks like our current API version is at 2019-03-14.

The API version should be manually changed in Stripe dashboard at the same
time as the commit is deployed in production.

Backward incompatible changes that are relevant to our codebase between
(2019-03-14, 2020-08-27].
* 2020-08-27 - The `sources` property on Customers is no longer included by
  default.
* 2020-03-02 - Nothing applicable
* 2019-12-03 - The `id` field of all invoice line items have changed and are
  now prefixed
  with `il_`. We only rely on this while we normalize the fixtures.
* 2019-11-05 - Nothing applicable
* 2019-10-17 - The `billing` attribute on invoices, subscriptions, and
  subscription schedules is renamed to`collection_method`. The invoice
  change is the one that is relevant to us.
* The customer object’s `account_balance` value has been renamed to
  `balance`. Only used for the stubs at the moment.
* 2019-10-08 - Nothing applicable
* 2019-09-09 - Nothing applicable
* 2019-08-14 - Nothing applicable
* 2019-05-16 - Nothing applicable

Also normalize the following IDs in stripe fixtures

* price_[A-Za-z0-9]{24}
* prod_[A-Za-z0-9]{14}
* pi_[A-Za-z0-9]{24}
* il_[A-Za-z0-9]{24}

Vishnu KS 50950de24c billing: Void open invoices of small realms without an active plan.
Previously, we only downgraded and voided small organizations behind
payments only if they had an active plan.

This left us with a bunch of invoices from small realms which used to
have an active plan. It doesn't make much sense for us to get these
realms to pay the invoices so we have decided to just void them. This
commit voids the open invoices of all the small realms without an active
plan and has the last invoice open. Unlike, the realms with an active
plan we don't email them about us voiding the invoice. It's not super
obvious whether Stripe sends an email to the customer when the Invoice
is voided. But they do get the message that the invoice is voided if
they try to pay the invoice through the hosted invoice page.

Vishnu KS b3d3539306 billing: Only fetch customers with stripe customer id in autodowngrade.

Vishnu KS 292932f3a4 tests: Use expected values list for avoiding duplicate code.
This avoid some duplicate code as well as improve the readability since
before we were checking for the expected values far away from the
definition of realm. Now we define the expected values right after the
realm definition which improves the code readability.
Also, this get removes the postfixing of realm variable names with numbers.
The postfixing is kind of mess since if we want add any new realm in between
the realms we need to renumber a lot of realm variables.

Vishnu KS eee02a3403 billing: Create customer_has_last_n_invoices_open function.
An additional check for whether customer.stripe_customer_id is
None is added to the function. That check was not really required before
since all the customers with a plan also have a valid value for
stripe_customer_id. So all the calls to stripe.Invoice.list would have
non None value for customer argument.

Even though that is the case, mypy should still have complained about
the possibility of customer.stripe_customer_id being None when passed to
stripe.Invoice.list as customer paramater since mypy don't know that
customers with a plan will always have a non empty value for
stripe_customer_id. Our stripe stubs expect a non empty value for
the customer parameter of stripe.Invoice.list. This is despite the
fact that stripe.Invoice.list can actually be called with customer set
to None. This returns the invoices from the entire organization.
Though, we still decided to ensure that the value of customer should be
non empty since there is no reason for us to ever call this function
with customer set to None. You can just call the function wuthout the
customer argument instead. So this requirement of a non None customer
paramater is useful for catching bugs.

The reason mypy didn't complain was because the type of
Customer.objects.all() is Any and not QuerySet[Customer]. So mypy has no
idea that customer.stripe_customer_id can be theoratically None even
though it was not possible in this [articular case as explained before.
I verified that this was the reason mypy didn't complain by using the
reveal_type function on Customer.objects.all() and the customer object.
After the refactoring it's super to obvious to mypy that the type of the
customer is Customer since it's mentioned in the function defintion. So it
was able to complain about the possibility of customer.stripe_customer_id
being None after the refactoring.
