Now that we allow multiple users to have registered the same token, we
need to configure calls to unregister tokens to only query the
targeted user_id.
We conveniently were already passing the `user_id` into the push
notification bouncer for the remove API, so no migration for older
Zulip servers is required.
Previously, Zulip did not correctly handle the case of a mobile device
being registered with a push device token being registered for
multiple accounts on the same server (which is a common case on
zulipchat.com). This was because our database `unique` and
`unique_together` indexes incorrectly enforced the token being unique
on a given server, rather than unique for a given user_id.
We fix this gap, and at the same time remove unnecessary (and
incorrectly racey) logic deleting and recreating the tokens in the
appropriate tables.
There's still an open mobile app bug causing repeated re-registrations
in a loop, but this should fix the fact that the relevant mobile bug
causes the server to 500.
Follow-up work that may be of value includes:
* Removing `ios_app_id`, which may not have much purpose.
* Renaming `last_updated` to `data_created`, since that's what it is now.
But none of those are critical to solving the actual bug here.
Fixes#8841.
There are several situations in which we want to create a Customer and
stripe.Customer object before we really have a billing relationship with a
customer. The main one is giving non-profit or educational discounts.
We've had this sort of logic for GCM for a long time; it's worth
adding for APNS as well.
Writing this is a bit of a reminder that I'm not a fan of how our unit
tests for push notifications work.
This completes the separation of our logic for managing Stripe
customers from the view code for the billing page.
As we add more features to our Customer model and to our Stripe
integration, we might further separate those two things; but for now
they're nearly synonymous and there's no problem in them being mixed
together.
Pull the code that talks to Stripe out into its own functions.
In a followup commit we'll move these to a separate file, as well
as the error-handling logic that remains in the view function
for now.
Also fix the translation markings: the translated string must be a
constant (e.g. a format string), or else translation is impossible.
Viewing with `-b` shows the few changes that happen in the logic
as it moves out of the view function; viewing without shows the
few changes in the rest of the view function.
Several changes:
* De-duplicate code for different error types.
* No need to list lots of error subtypes where we aren't treating
them differently; StripeError is the base class of them all.
* Unexpected, non-Stripe-related, exceptions we can handle in the normal
way. Just make them show up in the billing-specific log too.
* The Stripe client library already logs type, code, param, and message
before raising an error, so we don't need to repeat those; just add the
HTTP status code (because it's not there already and sure why not),
and the Python exception type the client library chose to raise
in case that makes things a bit easier to interpret.
Normal server admins will never run this code, and zulipchat.com will
have this information configured before users see it, so this message
is really just for development.
Stripe Checkout means using JS code provided by Stripe to handle
almost all of the UI, which is great for us.
There are more features we should add to this page and changes we
should make, but this gives us an MVP.
[greg: expanded commit message; fixed import ordering and some types.]
And it works!
A couple of things still to do:
* When a device token is no longer active, we'll get HTTP status 410.
We should then remove the token from the database so we don't keep
trying to push to it. This is fairly urgent.
* The library we're using has a nice asynchronous API, but this
version doesn't use it. This is OK now, but async will be
essential at scale.
This prevents a buggy old Zulip server from forwarding invalid-format
push notification tokens to the push notification bouncer service.
As part of this change, we switch the token from Text to str to match
the rest of the code path.
This is an incomplete cleaned-up continuation of Lisa Neigut's push
notification bouncer work. It supports registration and
deregistration of individual push tokens with a central push
notification bouncer server.
It still is missing a few things before we can complete this effort:
* A registration form for server admins to configure their server for
this service, with tests.
* Code (and tests) for actually bouncing the notifications.
This feature has been obsolete since when Zulip was released as open
source software, since it's purpose was to avoid putting a "server
url" prompt in the desktop app, and now that prompt is required
anyway.
A lot of care has been taken to ensure we're using the realm that the
message is being sent into, not the realm of the sender, to correctly
handle the logic for cross-realm bot users such as the notifications
bot.
Finishes the refactoring started in c1bbd8d. The goal of the refactoring is
to change the argument to get_realm from a Realm.domain to a
Realm.string_id. The steps were
* Add a new function, get_realm_by_string_id.
* Change all calls to get_realm to use get_realm_by_string_id instead.
* Remove get_realm.
* (This commit) Rename get_realm_by_string_id to get_realm.
Part of a larger migration to remove the Realm.domain field entirely.
For a long time, rest_dispatch has had this hack where we have to
create a copy of it in each views file using it, in order to directly
access the globals list in that file. This removes that hack, instead
making rest_dispatch just use Django's import_string to access the
target method to use.

ways by tabbott]
Also fix the annotation of zilencer.views.report_error.
The `report` arguments are a Dict containing both strings and the
`more_info` sub-dictionary, so we type them as Dict[str, Any].
[tweaked by tabbott]
All usages of json_to_dict were replaced with the check_dict
validator. The check_dict validations can eventually be
extended to validate the keys and values of incoming data,
but now we just use check_dict([]) in all the places where
we had json_to_dict, which means we aren't checking for any
specific keys; we are just making sure it's a dictionary.

An earlier commit today made it so that we don't create tickets
for feedback if the Python process had seen a message from that
user in the last few minutes. This doesn't help much when you
have multiple processes, so now we track the times in redis.

Now that we support email aliases, we have to be careful when going from
an email address to a domain that we assume we can use to get a Realm
object for. When we care about the Realm's domain, we want to follow
any RealmAliases that exist for a certain domain.
When we just care about the original email address domain itself,
for comparison or other purposes, use split_email_from_domain
This removes the ambiguity of having to decide when to use
email_to_domain + RealmAlias or just email_to_domain
