get_remote_server_by_uuid (called in validate_api_key) raises
ValidationError when given an invalid UUID due to how Django handles
UUIDField. We don't want that exception and prefer the ordinary
DoesNotExist exception to be raised.
APNs payloads nest the zulip-custom data further than the top level,
as Android notifications do. This led to APNs data silently never
being truncated; this case was not caught in tests because the mocks
provided the wrong data for the APNs structure.
Adjust to look in the appropriate place within the APNs data, and
truncate that.
As explained in the comments in the code, just doing UUID(string) and
catching ValueError is not enough, because the uuid library sometimes
tries to modify the string to convert it into a valid UUID:
>>> a = '18cedb98-5222-5f34-50a9-fc418e1ba972'
>>> uuid.UUID(a, version=4)
UUID('18cedb98-5222-4f34-90a9-fc418e1ba972')
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.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
This makes logging more consistent between FCM and APNs codepaths, and
makes clear which user-ids are for local users, and which are opaque
integers namespaced from some remote zulip server.
Being able to determine how many distinct users are getting push
notifications per remote host is useful, as is the distribution of
device counts. This parallels the log line in
handle_push_notification for push notifications from local realms,
handled via the event queue.
aioapns already has a retry loop. By default it retries forever on
ConnectionError and ConnectionClosed, so our own retry loop would
never be reached. Remove our retry loop, and configure aioapns to
retry APNS_MAX_RETRIES times on ConnectionError like the previous
version did. It still retries forever on ConnectionClosed; that’s not
configurable but probably fine.

These changes are all independent of each other; I just didn’t feel
like making dozens of commits for them.

Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:
1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.
Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)
then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.
The buggy code was this in `handle_push_notifications`:
```
if not (
receives_offline_push_notifications(user_profile)
or receives_online_push_notifications(user_profile)
):
return
// send notifications
```
This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.
2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).
3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.
This fixes a batch of mypy errors of the following format:
'Item "None" of "Optional[Something]" has no attribute "abc"
Since we have already been recklessly using these attritbutes
in the tests, adding assertions beforehand is justified presuming
that they oughtn't to be None.
This reduces loose strings in the codebase, and allows us to not worry
about the exact naming (`stream_email_enabled` or `stream_emails_enabled`?)
and tense (`mentioned` or `mention`?).
Ideally this new class should have been in `lib/notification_data.py`,
which is our file for things like this. But, the next commit requires
using this data in `models.py`, and importing from `notification_data.py`
to `models.py` causes recursive imports.
The code to also notify for wildcard mentions was added in
0ed0bb6828.
But that showed the same text for both the cases. This commit fixes
that.
This is more of change for correctness. The mobile app currently does
not rely on this text for notifications, but constructs the text by
itself from the data in the payload.
This also fixes the "stream_push_notify" case to consistently show
a `#` before the stream name.
The previous string was bold, potentially confusing, and doesn't
explain clearly what's happening. We replace this with a string that's
more or less copied from what we do in email notifications with the
similar setting enabled.
It was unclear what the original test was testing, and more
importantly, the test passed even if one removed the `read` flag
check in the `handle_push_notifications` function, so we fix it
to be more comprehensive.
Changed the name of the test-user cordelia from `Cordelia Lear` to
`Cordelia, Lear's daughter`.
This change will enable us to test users with escape characters in
their names.
I also updated the Node, Puppeteer, Backend tests and Fixtures to
support this change.
