Tim Abbott d2970a56c2 lint: Remove some unused imports.
These were introduced in ae5bc92602.

Vishnu KS ae5bc92602 queue: Don't create confirmation objects twice during invite.
A confirmation object is already created when
do_send_confirmation_email is called just above.

Tweaked by tabbott to remove an unnecessary somewhat hacky database
query.

Tim Abbott 1c73ce2450 user_activity: Use LoopQueueProcessingWorker strategy.
This should dramatically improve the queue processor's performance in
cases where there's a very high volume of requests on a given endpoint
by a given user, as described in the new docstring.

Until we test this more broadly in production, we won't know if this
is a full solution to the problem, but I think it's likely.  We've
never seen the UserActivityInterval worker end up backlogged without a
total queue processor outage, and it should have a similar workload.

Fixes #13180.

Tim Abbott f0d8951035 do_update_user_activity: Refactor to support passing a count.

Tim Abbott 5c960b3e0f user_activity: Make the queue processor a bit more efficient.
We don't actually need to go to the memcached (falling back to the
database) to fetch either user or client objects on every event.  For
user objects, we actually can just pass through the user ID
transparently; for client objects, we can use an in-process cache,
since the mapping of string to ID never changes.

Rishi Gupta e058558a52 emails: Send invitation reminder email two days before expiry.
Hopefully this does a better job of spurring people to action, and also
suggests a self-service fix if they don't (i.e. contacting the person that
invited them).

These were only missed because mypy daemon mode requires us to set
`follow_imports = skip` for the `zulip` package.

Wyatt Hoodes 7d178bbb0f queue_processors: Clean up the extra_data dict code.
We don't want to add a `deleted_timestamp` key until
the export is actually deleted.
2019-08-12 17:51:46 -07:00
Wyatt Hoodes 22842dab34 events: Rename notify_export_completed.
notify_realm_export is more reasonable for the context of doing
deletion events as well.

Wyatt Hoodes bbbea9ec87 events: Rewrite system for managing realm exports.
This feature is intended to cover all of our ways of exporting a
realm, not just the initial "public export" feature, so we should name
things appropriately for that goal.

Additionally, we don't want to include data exports in page_params;
the original implementation was actually buggy and would have.

Wyatt Hoodes d070f27359 queue_processors: Change the extra_data field to a relative url path.
A better approach as compared to saving the full public url.
2019-07-26 15:50:02 -07:00
Wyatt Hoodes 5686821150 middleware: Change write_log_line to publish as a dict.
We were seeing errors when pubishing typical events in the form of
`Dict[str, Any]` as the expected type to be a `Union`.  So we instead
change the only non-dictionary call, to pass a dict instead of `str`.

Wyatt Hoodes db69cdbcde public_export: Add support for deleting export after access.
The RealmAuditLog object ID was stored in the event sent to the
deferred_work queue as a means to update the row's extra_data field.
The extra_data field then stores the location of the export.
2019-05-31 22:54:27 -07:00
Wyatt Hoodes c0ef6c2fc6 export: Add LOCAL_UPLOADS_DIR support to the export feature.
A unique path was created using the `LOCAL_UPLOADS_DIR` backend, similar
to the code used in `LocalUploadBackend`.  The exported tarball was
copied to the directory, and an nginx url was created to serve the file
publicly.

Tweaked by tabbott to output an actual URL.
2019-05-27 20:06:35 -07:00
Wyatt Hoodes 4dd8c133a9 export: Rename `--upload-to-s3` to be `--upload`.
The upload option will no longer be limited to strictly S3 uploads. This
commit serves as a preliminary step for supporting LOCAL_UPLOADS_DIR as
part of the public only export feature.

Wyatt Hoodes d4715f23d7 public_export: Add backend API endpoint for triggering export.
An endpoint was created in zerver/views.  Basic rate-limiting was
implemented using RealmAuditLog.  The idea here is to simply log each
export event as a realm_exported event.  The number of events
occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.

The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.

Upon completion of the export the realm admin(s) are notified.

Mateusz Mandera 1901775383 email_mirror: Add realm-based rate limiting.
Closes #2420

We add rate limiting (max X emails withing Y seconds per realm) to the
email mirror. By creating RateLimitedRealmMirror class, inheriting from
RateLimitedObject, and rate_limit_mirror_by_realm function, following a
mechanism used by rate_limit_user, we're able to have this
implementation mostly rely on the already existing, and proven over
time, rate_limiter.py code. The rules are configurable in settings.py in
RATE_LIMITING_MIRROR_REALM_RULES, analogically to RATE_LIMITING_RULES.

Rate limit verification happens in the MirrorWorker in
queue_processors.py. We don't rate limit missed message emails, as due
to using one time addresses, they're not a spam threat.

test_mirror_worker is adapted to the altered MirrorWorker code and a new
test - test_mirror_worker_rate_limiting is added in test_queue_worker.py
to provide coverage for these changes.

Tim Abbott 50dc317466 notifications: Rename notifications.py to email_notifications.py.
This library is entirely about email notifications specifically, and
this rename should help make the codebase more readable.

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.

Raymond Akornor 254bf4c08f send_email: Add support for passing language into send_future_email.
This adds language paramater to send_future_email. As a result, this
properly internationalizes invitation reminder emails, by passing
correct language into send_future_email.

Tim Abbott 02a79b677b send_email: Extract handle_email_format_changes and use.
Apparently, we have a second code path where we might try to call
send_email library functions on old data, namely in the
queue_processors codebase.  So we apply the same migration logic here.

Raymond Akornor 92dc3637df send_email: Add support for multiple recipients.
This adds a function that sends provided email to all administrators
of a realm, but in a single email. As a result, send_email now takes
arguments to_user_ids and to_emails instead of to_user_id and
to_email.

We adjust other APIs to match, but note that send_future_email does
not yet support the multiple recipients model for good reasons.

Tweaked by tabbott to modify `manage.py deliver_email` to handle
backwards-compatibily for any ScheduledEmail objects already in the
database.

Fixes #10896.

Tim Abbott adf27aae4c python: Remove now-unnecessary str_utils library.
This library was absolutely essential as part of our Python 2->3
migration process, but all of its calls should be either no-ops or
encode/decode operations.

Note also that the library has been wrong since the incorrect
refactoring in 1f9244e060.

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 5cec566cb9 queue_processors: Rewrite MissedMessageWorker to always wait.
Previously, MissedMessageWorker used a batching strategy of just
grabbing all the events from the last 2 minutes, and then sending them
off as emails.  This suffered from the problem that you had a random
time, between 0s and 120s, to edit your message before it would be
sent out via an email.

Additionally, this made the queue had to monitor, because it was
expected to pile up large numbers of events, even if everything was
fine.

We fix this by batching together the events using a timer; the queue
processor itself just tracks the items, and then a timer-handler
process takes care of ensuring that the emails get sent at least 120s
(and at most 130s) after the first triggering message was sent in Zulip.

This introduces a new unpleasant bug, namely that when we restart a
Zulip server, we can now lose some missed_message email events;
further work is required on this point.

Fixes #6839.

Steve Howell 69ee84bb14 refactor: Extract build_bot_request().
This fixes a couple things:

    * process_event() is a pretty vague name
    * returning tuples should generally be avoided
    * we were producing the same REST parameters in both
      subclasses
    * relative_url_path was always blank
    * request_kwargs was always empty

Now process_event() is called build_bot_request(),
and it only returns request data,
not a tuple of `rest_operation` and `request_data`.

By no longer returning `rest_operation`, there are
fewer moving parts.  We just have `do_rest_call` make
a POST call.
2018-10-11 16:12:07 -07:00
Steve Howell 16eff75e49 refactor: Simplify how we use base_url.
Before this change, we instantiated base_url into a superclass
of subclasses that returned base_url into a dictionary that
gets returned to our caller.

Now we just pull base_url out of service when we need to make
the REST call.

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.

Tim Abbott 7ea5987e5d errors: Use a setting to control the stream for slow-query logs.
We already had a setting for whether these logs were enabled; now it
also controls which stream the messages go to.

As part of this migration, we disable the feature in dev/production by
default; it's not useful for most environments.

Fixes the proximal data-export issue reported in #10078 (namely, a
stream with nobody ever subscribed to having been created).

These two classes are tricky to test, and nocoverage-ing them
