While it could make sense to print these logging statements at WARN
level on server startup, it doesn't make sense to do so on every
message (though it perhaps did make sense to do so before more recent
changes added good ways to discover you forgot to configure push
notifications).
Instead, we now just do a WARN log on queue processor startup, and
then at DEBUG level for individual messages.
Fixes#10894.
Fixes#10745.
Use get_display_recipient to get stream names, and remove the
references to message.stream_name in push_notifications.py which were
added in 97571a203, as the actual stream names were being retrived
only for Message objects associated with public streams.
Also, rename get_alert_from_message to get_gcm_alert.
With the implementation of the and get_apns_alert_title and
get_apns_alert_subtitle, the logic within get_alert_from_message
is only relevant to the GCM payload, so we adjust the name
accordingly.
Progresses #9949.
Resolves https://github.com/zulip/zulip-mobile/issues/1316.
The string that is returned from get_alert_from_message is
dependent upon the same message that is passed into get_apns_payload
and get_gcm_payload. The contents of those payloads that are tested via
TestGetAPNsPayload and TestGetGCMPayload, which makes the tests for
get_alert_from_message redundant.
Also, simplify the logic by removing the last elif conditional.
The APNS client libraries (especially the hyper.http20 one) were
determined via profiling to take significant time during the import
process, so we move them to be lazily imported in order to optimize
the overall Zulip import process. This save up to about 100ms in
import time.
These libraries are only used in certain Django processes inside
zulipchat.com, and so are unnecessary both in development as well as
for self-hosted Zulip servers.
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.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.
Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients. But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.
This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.
We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.
Fixes#7459, though we'll need to open a follow-up issue for
using these data on iOS.
This adds a new function called handle_remove_push_notification in
zerver/lib/push_notifications.py which requires user_profile id and
the message id which has to be removed in the function.
For now, the function only supports GCM (and is mostly there for
prototyping).
The payload which is being delivered needs to contain the narrow
information and the content of the message.
This should make it much simpler for the mobile apps to line up the
data from server_settings against the data in the notifications.
Addresses part of #10094.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

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.
If an Android token has been used to connect a given device with
multiple Zulip servers, and then is expired, we would 500 in trying to
remove the Zulip-side registration for it, because the code assumed
there was only one such registration. If a token is no longer valid,
it's invalid for all servers, so the correct fix is to just remove them all.
When the answer is False, this will allow the mobile app to show a
warning that push notifications will not work and the server admin
should set them up.
Based partly on Kunal's PR #7810. Provides the necessary backend API
for zulip/zulip-mobile#1507.
I got distracted, came back later to a successful test run in my
terminal, and thought I remembered finishing the change and just
kicking off a final test run to check.
In fact, there was an `assert False` right in the normal case for
production, and I just hadn't finished a test for that path. (m.-)
Definitely the most grateful I've been for our coverage checks,
which highlighted this for me.
Remove the `assert False`, and also finish writing the test it was
there to help me write. Those lines are covered now.
Previously, these push notification events were being generated, but
then ignored in handle_push_notification because there was no
user_message object.
This removes the utterly unnecessary `triggers` dict (which always was
a dict with exactly one value True) in favor of a single field,
'trigger'.
Inspired by Kunal Gupta's work in #6659.
This function truncates the textual content at correct length.
(It will be updated later to handle corner cases of unicode
combining characters and tags when we start supporting them.)
This is just enough of a quick fix to work with a stock Zulip 1.6
server. We should really also make this robust to arbitrary input
from the remote Zulip server, even though it'll be a little tedious.
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 code empirically doesn't work. It's not entirely clear why, even
having done quite a bit of debugging; partly because the code is quite
convoluted, and because it shows the symptoms of people making changes
over time without really understanding how it was supposed to work.
Moreover, this code targets an old version of the APNs provider API.
Apple deprecated that in 2015, in favor of a shiny new one which uses
HTTP/2 to meet the same needs for concurrency and scale that the old
one had to do a bunch of ad-hoc protocol design for.
So, rip this code out. We'll build a pathway to the new API from
scratch; it's not that complicated.
We'd been getting errors from APNs that appeared to say that the
device tokens we were trying to send to were invalid. It turned out
that the device tokens didn't match the "topic" (i.e. app ID) we were
sending, which was because the topic was wrong, which was because we
were using the wrong SSL cert. But for a while we thought it might be
that we were somehow messing up the device tokens we put into the
database. This logging helped us work out that wasn't the issue, and
would have helped our debugging sooner.
Now this function will delete tokens from RemotePushDeviceToken if it
is running on notification bouncer or PushDeviceToken if it is running
on a server which doesn't use notification bouncer.
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 completes the process of simplifying the interface of the
send_*_push_notification functions, so that they can effectively
support a push notification forwarding workflow.
This refactoring is preparation for being able to forward push
notifications to users on behalf of another Zulip server.
The goal is to remove access to the current server's database from the
send_*_push_notification code paths.
Now we have 2 different Zulip apps out there, and they are signed with
two certs: Zulip and Dropbox. The Dropbox-signed apps are going to need
to be sent APNS notifications from the appropriate APNS connection

While we're at it, lets comment up the function so I know what this is
doing next time :)
(imported from commit e745be75fcd6dbce9997e1d73464619fc8b73996)
This replaces the AppleDeviceToken table with a generic
PushDeviceToken with a `kind` field to make it easier to add functionality
like per-device/per-stream settings that share code between Android and
iOS devices.
The schema must continue to work on prod with the old table name, so we
add the new table in parallel and can drop the old table once this code
hits prod and any necessary data is copied.
