Mateusz Mandera abdfdeffe4 remote_billing: Implement confirmation flow for legacy servers.
For the last form (with Full Name and ToS consent field), this pretty
shamelessly re-uses and directly renders the
corporate/remote_realm_billing_finalize_login_confirmation.html
template. That's probably good in terms of re-use, but calls for a
clean-up commit that will generalize the name of this template and the
classes/ids in the HTML.

Prakhar Pratyush bf4fdbff12 stripe: Update LicenseLedger for remote realms.
When a remote server uploads statistics, we update the
LicenseLedger using the audit logs uploaded.

We iterate over the RemoteRealmAuditlog data for the concerned
realm starting from the event_time of the last LicenseLedger
created for that customer and update the ledger based on each event.

Prakhar Pratyush ed9b0d330d stripe: Raise 'MissingDataError' while fetching license count.
If the RemoteRealmAuditLog has stale data, it means the server
stopped or never uploaded data. We raise MissingDataError in such
cases when a user action led to calculating licenses count from
stale data.

Prakhar Pratyush 40621478cb zilencer: Add `get_remote_realm_guest_and_non_guest_count`.
We add a 'get_remote_realm_guest_and_non_guest_count'
function that queries 'RemoteRealmAuditLog' to get
the guest and non_guest count for that remote_realm.

This function is used in 'RemoteRealmBillingSession'
to calculate the current count of billed licenses.

Prakhar Pratyush bd99e37910 stripe: Use get_remote_server_guest...count for billing licenses count.

RemoteServerBillingSession.

Lauryn Menard 5eabd51702 corporate: Make is_sponsored_or_pending not abstract in BillingSession.
The logic for BillingSession.is_sponsored_or_pending would be the

Lauryn Menard 5d25cab42b analytics: Create process_support_view_request BillingSession method.
Creates a process_support_view_request method for BillingSession
to process the various support requests that relate to the billing
system.

Moves approve_realm_sponsorship, update_realm_sponsorship_status,
and attach_discount_to_realm to this new BillingSession method.

Adds a new abstract property to BillingSession to have a string
value, billing_entity_display_name, to use for support messages
sent when these requests are processed.
2023-12-03 14:27:07 -08:00
Lauryn Menard 0679bc044a corporate: Make references to billing modality consistent.
The "send_invoice" and "charge_automatically" strings used by stripe
for the `collection_method` are referred to both as the "billing
method" and "billing modality" in the billing code.

Because we send this as data to stripe as either `collection_method`
or `billing_modality`, renames any references that are any form of
"billing method".

Mateusz Mandera 544482eefb remote_billing: Add tests for the legacy server flow.

Mateusz Mandera 134e3bfa68 remote_billing: Add redirects to login for unauthed user in legacy flow.
Analogical to the more complex mechanism implemented for the RemoteRealm
flow in a previous commit in
authenticated_remote_realm_management_endpoint.

As explained in the code comment, this is much easier because:

In this flow, we can only redirect to our local "legacy server flow
login" page. That means that we can do it universally whether the user
has an expired
identity_dict, or just lacks any form of authentication info at all -
there are no security concerns since this is just a local redirect.
2023-12-03 10:39:56 -08:00
Mateusz Mandera ec7245d4e1 remote_billing: Add redirect flow for users with expired session.
Implements a nice redirect flow to give a good UX for users attempting
to access a remote billing page with an expired RemoteRealm session e.g.
/realm/some-uuid/sponsorship - perhaps through their browser
history or just their session expired while they were doing things in
this billing system.

The logic has a few pieces:
1. get_remote_realm_from_session, if the user doesn't have a
   identity_dict will raise RemoteBillingAuthenticationError.
2. If the user has an identity_dict, but it's expired, then
   get_identity_dict_from_session inside of get_remote_realm_from_session
   will raise RemoteBillingIdentityExpiredError.
3. The decorator authenticated_remote_realm_management_endpoint
   catches that exception and uses some general logic, described in more
   detail in the comments in the code, to figure out the right URL to
   redirect them to. Something like:
   https://theirserver.example.com/self-hosted-billing/?next_page=...
   where the next_page param is determined based on parsing request.path
   to see what kind of endpoint they're trying to access.
4. The remote_server_billing_entry endpoint is tweaked to also send
   its uri scheme to the bouncer, so that the bouncer can know whether
   to do the redirect on http or https.

Mateusz Mandera 5a198c639e remote_billing: Sort out remote_billing_identities typing.
This does two important things:
1. Fix return type of get_identity_dict_from_session to correctly be
   Optional[Union[RemoteBillingIdentityDict, LegacyServerIdentityDict]].
   RemoteBillingIdentityDict is the type in the 8.0+ auth flow,
   LegacyServerIdentityDict is the type in old servers flow, where only
   the server uuid info is available.
2. The uuid key used in request.session["remote_billing_identities"]
   should be explicitly namespaced depending on which flow and type
   we're
   dealing with - to avoid confusion in case of collisions between a
   realm and server that have the same UUID. Such a situation should not
   occur naturally and I haven't come up with any actual exploitation
   ideas that could utilize this by manipulating your server/realm
   uuids, but it's much easier to just not think about such collision
   security implications by making them impossible.

Updates do_change_plan_to_new_tier in BillingSession to use an

Lauryn Menard 39bfab0ec4 corporate: Move plan tier change to separate helper function.

Because the plan tier change is immediate, moves the code to end
the current plan with the old tier and create the new plan with
the new tier from `make_end_of_cycle_updates_if_needed` to instead

Mateusz Mandera 4fc2b54eed stripe: Set .api_version to make integration work again.
Upgrading stripe to 6.0.0 in e32366638a

For the upstream details see:

6.0.0 uses 2023-08-16 Stripe API version unless specified otherwise. We
want to use 2020-08-27.

Setting stripe.api_version in corporate/lib/stripe.py is sufficient for
it to be set everywhere else. This is supported by the fact that we also

Mateusz Mandera 07e99eace9 billing: Fix license counting in exempt_from_license_number_check case.
Fixes two bugs involving organization with
exempt_from_license_number_check enabled:
1. If the organization had e.g. 100 users and upgraded their plan,
   specifying 50 licenses, the generated LicenseLedger and thus the
   corresponding invoice was still for 100 users.
2. The organization was unable to use the billing/plan endpoint (update
   plan endpoint) to make their number of licenses less than the current
   number of users.

Organizations with exempt_from_license_number_check are supposed to be
able to declare whatever license number they want, as this attribute
allows having pricing schemes where an organization only pays us for a
subset of their users.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Zixuan Li e39e04c3ce
migration: Add `extra_data_json` for audit log models.
Note that we use the DjangoJSONEncoder so that we have builtin support
for parsing Decimal and datetime.

During this intermediate state, the migration that creates
extra_data_json field has been run. We prepare for running the backfilling
migration that populates extra_data_json from extra_data.

This change implements double-write, which is important to keep the
state of extra data consistent. For most extra_data usage, this is
handled by the overriden `save` method on `AbstractRealmAuditLog`, where
we either generates extra_data_json using orjson.loads or
ast.literal_eval.

While backfilling ensures that old realm audit log entries have
extra_data_json populated, double-write ensures that any new entries
generated will also have extra_data_json set. So that we can then safely
rename extra_data_json to extra_data while ensuring the non-nullable
invariant.

For completeness, we additionally set RealmAuditLog.NEW_VALUE for
the USER_FULL_NAME_CHANGED event. This cannot be handled with the
overridden `save`.

This addresses: https://github.com/zulip/zulip/pull/23116#discussion_r1040277795

Note that extra_data_json at this point is not used yet. So the test
cases do not need to switch to testing extra_data_json. This is later
done after we rename extra_data_json to extra_data.

Double-write for the remote server audit logs is special, because we only
get the dumped bytes from an external source. Luckily, none of the
payload carries extra_data that is not generated using orjson.dumps for
audit logs of event types in SYNC_BILLING_EVENTS. This can be verified
by looking at:

`git grep -A 6 -E "event_type=.*(USER_CREATED|USER_ACTIVATED|USER_DEACTIVATED|USER_REACTIVATED|USER_ROLE_CHANGED|REALM_DEACTIVATED|REALM_REACTIVATED)"`

Therefore, we just need to populate extra_data_json doing an
orjson.loads call after a None-check.

exempt_from_license_number_check was initially added allowing
organizations with it enabled to invite new users above their number of
licenses.

However, an organization with this permission enabled,
cannot upgrade if they weren't on a plan already - because when choosing
Manual license management, you cannot enter a number of licenses lower
than the current seat count. However, an organization like that probably
already has some users that they get free of charge - and thus they need
to be able to enter a lower number of licenses in order to upgrade.

Mateusz Mandera 6582a002e7 billing: Add comment about the calculation in get_latest_seat_count.
Our billing FAQ says:
"For an organization with N other users, 5*N guest users are included at
no extra charge. After that, you will be charged at 1/5 of your regular
per-user pricing for each additional guest.".

It wasn't quite intuitive to me that
max(non_guests, math.ceil(guests / 5)) achieves that pricing, so it's
worth mentioning in a comment that it does and that that's why that
formula is used.

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.
2021-07-22 17:56:35 -07:00
Vishnu KS b3d3539306 billing: Only fetch customers with stripe customer id in autodowngrade.
The customers without a value for stripe_customer_id never had an active

2021-07-22 17:56:35 -07:00
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.

Vishnu KS e64296b3e9 stripe: Create get_all_invoices function.
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.
2021-07-02 12:04:41 -07:00
Vishnu KS 1d579ec567 billing: Fix the type annotation of Customer.stripe_customer_id.
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.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
