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 feature has been obsolete since when Zulip was released as open
source software, since it's purpose was to avoid putting a "server
url" prompt in the desktop app, and now that prompt is required
anyway.
Change `from django.utils.timezone import now` to
`from django.utils import timezone`.
This is both because now() is ambiguous (could be datetime.datetime.now),
and more importantly to make it easier to write a lint rule against
datetime.datetime.now().
This fixes an issue where one would get errors of the form:
`ValueError: unsupported pickle protocol: 3`
in a `run-dev.py` server run against Python 2 if you ran `provision`.
Provision currently runs `populate_db` with Python 3, storing Python 3
based data in memcached, which then can't be read by Python 2.
The realm with string_id of "simple" just has three users
named alice, bob, and cindy for now. It is useful for testing
scenarios where realms don't have special zulip.com exception
handling.
This old helper has for years been used only by populate_db, and got
buggy (as of a recent refactoring). So we just call do_send_messages
directly instead.
Fixes the provisioning error we currently get in Travis CI.
A lot of care has been taken to ensure we're using the realm that the
message is being sent into, not the realm of the sender, to correctly
handle the logic for cross-realm bot users such as the notifications
bot.
Finishes the refactoring started in c1bbd8d. The goal of the refactoring is
to change the argument to get_realm from a Realm.domain to a
Realm.string_id. The steps were
* Add a new function, get_realm_by_string_id.
* Change all calls to get_realm to use get_realm_by_string_id instead.
* Remove get_realm.
* (This commit) Rename get_realm_by_string_id to get_realm.
Part of a larger migration to remove the Realm.domain field entirely.
First step in cleaning up populate_db.create_streams and
bulk_create.bulk_create_streams. Part of a series of commits to remove
Realm.domain from populate_db.
