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}
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.
An organization with at most 5 users that is behind on payments isn't
worth spending time on investigating the situation.
For larger organizations, we likely want somewhat different logic that
at least does not void invoices.
stripe.Invoice.list by default would only get 10 invoices at a
time. So a function like this would be really handy if we have
to go through a lot of invoices.
This also means void_all_open_invoices used to void only the last
10 invoices. The main reason we implemented this function was to
void the invoices generated by realms on free trial so I don't
think there were cases where we had to void realms with more than
10 invoices.
This also fixes a bug in void_all_open_invoices function. If a realm
with a local Customer object but without an associated stripe.Customer
is passed to void_all_open_invoices, then the function will end up
voiding the last 10 invoices created by billing system instead of voiding
no invoices at all. This is because stripe.Invoice.list(customer=None)
return last 10 invoices across all customers.
But this bug won't cauuse any issue in production since
void_all_open_invoices can be only invoked from /support page. And we
show the option to void invoices in support page only if the realm
has a paid plan. And it's not really possible for a realm to have
a paid plan without having an associated stripe_customer_id. Plus I
went through the void events in stripe stream since the PR to add
void invoices was merged and there does not seems to be any suspicious
events.
These fixtures were added in 4aa2ac1b52.
The fixture name mentions renewal as the test function name. But we
don't have any function called test_renewal in test_stripe file. This
likely means the fixtures were accidentally added. Also, deleting all
fixtures and running --generate-stripe-fixtures don't result in these
fixtures getting generated as well.
Previously, when users got a "payment failed" email from Stripe (e.g. if
their card failed on renewal), they would enter in a new card on
/billing#payment-method, and wouldn't find out if the card worked till
Stripe retried the payment 4 days later.
This is a major rewrite of the billing system. It moves subscription
information off of stripe Subscriptions and into a local CustomerPlan
table.
To keep this manageable, it leaves several things unimplemented
(downgrading, etc), and a variety of other TODOs in the code. There are also
some known regressions, e.g. error-handling on /upgrade is broken.
A lot of the seemingly unrelated test fixture changes are because we're
removing a query to stripe in the upgrade path, in cases when the user's
realm has an existing Customer object.
The fixture changes are because self.upgrade formerly used to cause a page load
of /billing, which in turn calls Customer.retrieve.
If we ran the full test suite with GENERATE_STRIPE_FIXTURES=True, we would
likely see several more Customer.retrieve.N.json's being deleted. But
keeping them there for now to keep the diff small.
f52e9d1 ended up not going far enough. Keeping f52e9d1 in place in case we
ever want to go back to that sort of solution.
Also removes the keep argument from test_billing_quantity_changes_end_to_end,
since that test is actually testing the arguments to
stripe.Subscription.save(), not what is returned by Stripe.
Reran every test with GENERATE_STRIPE_FIXTURES = True, which also caused a
few fixtures to get updates unrelated to these changes (likely due to API
updates that hadn't been previously applied).
Also fixes a bug in process_initial_upgrade. If you have a card on file
(e.g. from a previous subscription), and try to upgrade by billing by
invoice, neither the if nor the elif condition applies.
Was hoping to do this after adding timestamp normalization to
normalize_fixture_data, which would have turned this into a <10 line
diff. There is a potentially material change in this API upgrade though
(around how invoices are handled), so just doing it now.
This makes a few other changes to the fixtures as well. Most are from API
updates, though I'm not sure why "Zulip Cloud Standard" got changed to
"Zulip Cloud Premium".
