Adds a new webhook integration for Slack to receive messages
from one's Slack team's public channels.
Contains negative tests for broken, missing or invalid data.
Allows two different option for integration:
1. Receive notification on a single stream with different topics
for each of Slack's public channels.
2. Receive notification on different streams for each of Slack's
public channels.
Steps to choose between the two options is described in the documentation.
Fixes#3569.
This fixes 2 issues:
* Being added to an invite_only stream did not correctly update the
"streams" key of the initial state.
* Once that's resolved, subscribe_to_stream when called on a
nonexistant stream would both send a "create" event (from
create_stream_if_needed) and an "occupy" event (from
bulk_add_subscriptions).
The second event should just be suppressed in that case, and this
implements that suppression.
We previously didn't apply the default language event change
correctly.
Not super important as a bug, since we require the user to reload the
browser for their changes to take effect, but this will save time if
we ever change that.
This makes it possible for us to do some convenient validation for
developers, checking whether the correct types are passed for each
each realm property.
zerver/lib/actions: removed do_set_realm_* functions and added
do_set_realm_property, which takes in a realm object and the name and
value of an attribute to update on that realm.
zerver/tests/test_events.py: refactored realm tests with
do_set_realm_property.
Kept the do_set_realm_authentication_methods and
do_set_realm_message_editing functions because their function
signatures are different.
Addresses part of issue #3854.
This makes get_stream match get_realm, get_user_profile_by_email,
etc., in interface, and is more convenient for mypy annotations
because `get_stream` now doesn't return an Optional[Stream].
Apparently, Django's CSRF protection mechanism changed at some point,
and now we get a different CSRF token every time the webapp is loaded.
This, in turn, caused our reload logic to avoid losing state to be
completely ineffective, since the CSRF check in reload.initialize
always failed.
We fix this in a secure fashion by passing the reload instructions
from the browser to its reloaded self via localstorage, keyed by a
randomly generated token. The token randomization is primarily
relevant for handling several Zulip tabs in the same browser, but also
servers to make it very difficult for an attacker to ever trigger this
code path by redirecting a browser to `/#reload` URLs.
Fixes#3411.
Fixes#3687.
This was actually being done in 2 ways: via not saving the narrow in
the reload and second through calling `change_tab_to('#home')`. The
code is so ancient that it seems unlikely that this behavior was still
intentional.
Fixes part of #3687 (the remainder is fixed in a few commits).
We use the same strategy Zulip already uses for starred messages,
namely, creating a new UserMessage row with the "historical" flag set
(which basically means Zulip can ignore this row for most purposes
that use UserMessage rows). The historical flag is ignored, however,
in determining which users' browsers to notify about new reactions,
and thus the user will get to see the reaction appear when they click
a message (and any reactions other users later add, as well!).
There's still something of a race here, in that if some users react to
a message while the user is looking at the unsubscribed stream but
before the user reacts to that message, those reactions will not be
displayed to that user (so counts will be a bit lower, or something).
This race feels small enough to ignore for now.
Fixes#3345.
