Tim Abbott 2d11e163dd push_notifications: Move "push" part of URLs to callers.
This will make it possible for us to use this library for endpoints
not directly related to push notifications.
2019-01-31 15:22:00 -08:00
Tim Abbott 88fae0b6a9 remote_server: Extract remote_server.py library.
This moves the network request code for connecting to the push
notification bouncer service into its own module.
2019-01-31 15:08:46 -08:00
Tim Abbott 0ffc2ce183 push_notifications: Don't rename import for lxml.html.
This is our standard way of writing code.
2019-01-07 13:15:46 -08:00
Tim Abbott b1cb38e7a0 push_notifications: Remove an unnecessary else clause.
This makes the code a bit cleaner.

ishanrai05 4105fb683b notifications: Optimize push notifications code path in tests.
This checks if push_notification_enabled() is set to false in
handle_push_notification and adds an early return statement.

This is a significant performance optimization for our unit tests
because the push notifications code path does a number of database
queries, and this migration means we don't end up doing those queries
the hundreds of times we send PMs or mentions in our tests where we're
not trying to test the push notifications functionality.

This should also have a small message sending scalability improvement
for any Zulip servers without push notifications enabled.

Tweaked by tabbott to fix a few small issues.

Fixes #10895.

Tim Abbott 27f3919259 push_notifications: Also treat ConnectionError as a retry.
It's a bug that the HTTP20 library isn't catching these, but we just
have to work around it.
2018-12-12 09:40:51 -08:00
Tim Abbott 914ae88c62 push_notifications: Expand APNS main try/except block.
We should be catching exceptions trying to send the notice as well as
in the result section.
2018-12-12 09:40:51 -08:00
Tim Abbott 380231af9d push_notifications: Add tests for BrokenPipeError case.
This was missing in d723dbfef7.
2018-12-05 10:44:25 -08:00
Tim Abbott b47535d8bb push notifications: Fix exception when handling deleted messages.
If a user deletes message between when it triggered a potential push
notification for another user, and when that notification was actually
sent, we'd end up with a situation where the `Message` table didn't
have an entry for the requested message ID.

The clean fix for this is to still throw an exception in the event
that the message doesn't exist at all, but if it exists in
ArchivedMessage, don't throw a user-facing exception.

Tim Abbott d723dbfef7 push_notifications: Handle BrokenPipeError from APNS.
This seems to happen when Apple is having a partial outage on some of
their APNS shards; it should be treated like other networking errors
connecting to APNS (with an automatic retry).
2018-12-05 10:02:18 -08:00
Tim Abbott 4c1e80032a push notifications: Fix unnecessary warning in development.
This prevents the warning about push notifications not being
registered for from being printed in development environment startup
by default.  In development, that's the expected state, and we don't
need to spam up the output with that notice.
2018-12-03 12:03:56 -08:00
Tim Abbott 10e8e2acac push notifications: Tweak text for push notification message.
The previous content made it sound like we were actually sending a
push notification, which could be confusing/alarming in some cases
(see e.g. 9c224ccdd3).  Instead, we make
clear that we're sending it to all clients (which one might correctly
suspect is vacuous in the development environment).
2018-11-27 09:53:44 -08:00
Tim Abbott 7b930124d9 push notifications: Add a logger (default-off in tests).
This should suppress some spammy logging output about push
notifications that we were seeing in a large number of unit tests.
2018-11-27 09:45:45 -08:00
Tim Abbott 38a6003472 push notifications: Improve logging for missing configuration.
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.

Tim Abbott beb80219a8 push notifications: Fix a comment typo. 2018-11-27 09:18:35 -08:00
Steve Howell cd4d447d90 Minor: change message.subject -> message.topic_name().
This also allows us to lock down
push_notifications.py from using "subject"
in the future.

Jack Zhang 5902a573be push_notifications: Play 'default' sound for iOS notifications.
Fixes zulip/zulip-mobile#2651.

This was tested on an iPhone 7 running iOS 12.

Jack Zhang 3d6a745047 notifications: Show stream names for private stream messages.
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.

Jack Zhang f116aba490 push notifications: Reword APNs payload alert titles.
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.
2018-10-26 16:02:04 -07:00
Jack Zhang 92a100798c push notifications: Remove tests for get_alert_from_message.
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.

Tim Abbott 695d8d0bd1 get_apns_payload: Require a UserProfile object for the recipient.
This is preparatory work for being able to display an unread count
badge on iOS, in which case we need to know who the current user is.
2018-10-18 15:09:18 -07:00
Tim Abbott 2eebacf2dc push_notifications: Lazily import APNS libraries.
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.

Tim Abbott 68ab71eb8b push: Fix exceptions when removing push notifications.
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.
2018-10-12 11:19:23 -07:00
Tim Abbott c57c4cf703 notifications: Fix push notifications with multiple realms.
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.

Tim Abbott 54e90deda8 notifications: Handle APNS "Unregistered" errors properly.
Apparently, the APNS library we're using is inconsistent about the
format of its result entries; some are strings while others are
tuples.

Tim Abbott da8f4bc0e9 push notifications: Add support for removing GCM push notifications.
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.
2018-08-10 13:58:39 -07:00
Tim Abbott e9f4d9db2b push_notifications: Fix interface for handle_remove_push_notification.
This really should just accept a message ID.
2018-08-01 16:36:42 -07:00
Kunal Gupta bc43eefbfb notifications: Add function for cancelling GCM notifications.
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.
2018-08-01 15:59:04 -07:00
Tim Abbott 5f8d193bb7 notifications: Include realm_uri in push notifications.
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.

Anders Kaseorg 037f696d26 Enable pycodestyle W605 (invalid escape sequence).
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'.

Tim Abbott cec7686f3d push notifications: Clean up unregistered/bad APNS tokens.
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.

Tim Abbott 62c0d27d1e push_notifications: Handle errors with token reuse.
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.

Greg Price ecbc72b857 push notifs: Add a diagnostic in API of whether push notifs enabled.
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.

Greg Price 8be2dfa81c APNs: Fix a case I broke while working out tests.
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.
