Tim Abbott 0be35f530b push_notifications: Replace 'REDACTED' string.
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.

Shelly c958a023fe i18n: Add i18n to 'REDACTED' message in push notifications.
When a user has disabled message content in mobile push notifications,
we send a fixed string (currently "REDACTED") as the content of the
notification. Previously, this string was not tagged for translation;
we fix that here.

Additionally, because mobile push notifications are generated in a
queue worker, they do not have the user's language set by the Django
middleware. Our email notifications solve that problem using
`override_language`; we do the same here.

We choose to do override_language in get_message_payload_apns and
get_message_payload_gcm, rather than the caller, in order to be
consistent with tests.

Tested end-to-end by tabbott by setting a translation for "REDACTED"
manually in German.

Fixes #18713.

Hashir Sarwar ab6be2a711 push_notifications: Store tokens locally even when bouncer is used.
This makes the system store and track PushDeviceToken objects on
the local Zulip server when using the push notifications bouncer
and includes tests for this.

This is something we need to implement end-to-end encryption for
push notifications. We'll add the encryption key as an additional
property on the local PushDeviceToken object.

It also likely adds some value in the case that a server were to
switch between using the bouncer service and sending notifications
directly, though in practice that's unlikely to happen.

Mateusz Mandera 7d0444f903 push_notifs: Improve handling of errors when talking to the bouncer.
We use the plumbing introduced in a previous commit, to now raise
PushNotificationBouncerRetryLaterError in send_to_push_bouncer in case
of issues with talking to the bouncer server. That's a better way of
dealing with the errors than the previous approach of returning a
"failed" boolean, which generally wasn't checked in the code anyway and
did nothing.
The PushNotificationBouncerRetryLaterError exception will be nicely
handled by queue processors to retry sending again, and due to being a
JsonableError, it will also communicate the error to API users.
2019-12-04 09:58:22 -08:00
Mateusz Mandera 20b30e1503 push_notifs: Set up plumbing for retrying in case of bouncer error.
We add PushNotificationBouncerRetryLaterError as an exception to signal
an error occurred when trying to communicate with the bouncer and it
should be retried. We use JsonableError as the base class, because this
signal will need to work in two roles:
1. When the push notification was being issued by the queue worker
PushNotificationsWorker, it will signal to the worker to requeue the
event and try again later.
2. The exception will also possibly be raised (this will be added in the
next commit) on codepaths coming from a request to an API endpoint (for
example to add a token, to users/me/apns_device_token). In that case,
it'll be needed to provide a good error to the API user - and basing
this exception on JsonableError will allow that.

Thomas Ip 574c35c0b8 markdown: Render ordered lists using <ol> markup.
This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.

On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.

Using <ol> here necessarily removes the behaviour of not renumbering

change.

Vishwesh Jainkuniya c007b9ea4a notifcations: Remove `user` from the payload.
This contains email of the user to whom notification is being

safe to remove it.

As user_id will be stable for the user, but not email. So it's better to

Greg Price 9869153ae8 push notif: Send a batch of message IDs in one `remove` payload.
When a bunch of messages with active notifications are all read at
once -- e.g. by the user choosing to mark all messages, or all in a
stream, as read, or just scrolling quickly through a PM conversation
-- there can be a large batch of this information to convey.  Doing it
in a single GCM/FCM message is better for server congestion, and for
the device's battery.

The corresponding client-side logic is in zulip/zulip-mobile#3343 .

Existing clients today only understand one message ID at a time; so
accommodate them by sending individual GCM/FCM messages up to an
arbitrary threshold, with the rest only as a batch.

Also add an explicit test for this logic.  The existing tests
that happen to cause this function to run don't exercise the
last condition, so without a new test `--coverage` complains.

Greg Price 0213aa0b16 push notif: Don't forget to clear "active" flag on sending to bouncer.
Since da8f4bc0e back in August, this control flow has caused
`flags.active_mobile_push_notification` to be cleared if we don't send
these `remove` messages at all, and if we send them directly to GCM...
but not if we send them via the Zulip notification bouncer.

As a result, on a server configured to send `remove` notification-messages
via the bouncer, we accumulate "active" messages and never clear them.

If the user then does `mark_all_as_read`, we end up sending a `remove`
for each of those messages again, and all in one giant burst.  We've
seen puzzling bursts of hundreds of removals pass through the bouncer
since turning on removals on chat.zulip.org; it's likely many of them
are caused by this bug.

This issue was made more acute with f4478aad5, which unconditionally
enabled removals.

Greg Price f4478aad54 push notif: Unconditionally remove notifications on message read.
The client-side fix to make these not a problem was in release
16.2.96, of 2018-08-22.  We've been sending them from the
development community server chat.zulip.org since 2018-11-29.
We started forcing clients to upgrade with commit fb7bfbe9a,
deployed 2018-12-05 to zulipchat.com.

(The mobile app unconditionally makes a request to a route on
zulipchat.com to check for this kind of forced upgrade, so that
applies to mobile users of any Zulip server.)

So at this point it's long past safe for us to unconditionally
send these.  Hardwire the old `SEND_REMOVE_PUSH_NOTIFICATIONS`
setting to True, and simplify it out.

That is, this allows a Zulip server to now set the `priority`; but if
it doesn't, we use upstream's default value, which has the same effect
as we've always previously had by not setting it at all.

But when this is deployed to the push notifications bouncer server, it

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 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 4c1e80032a push notifications: Fix unnecessary warning in development.
This prevents the warning about push notifications not being

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).

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.

Use get_display_recipient to get stream names, and remove the

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.

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 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

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

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'.
