sahil839 c488a35f10 streams: Add API for changing stream-level message_retention_days.
This commit adds backend support for setting message_retention_days
while creating streams and updating it for an existing stream. We only
allow organization owners to set/update it for a stream.

'message_retention_days' field for a stream existed previously also, but
there was no way to set it while creating streams or update it for an
exisiting streams using any endpoint.

Rohitt Vashishtha 6ea3816fa6 markdown: Use html5 <time> tag for timestamps.
Previously, we had implemented:
    <span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
    <time timestamp="ISO 8601 string">Original text</time>
    <span class="timestamp-error">Invalid time format: Original text</span>

Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.

Fixes #15431.

Aman Agrawal b7e5b7f193 do_update_messages: Delete user_message if guest user loses access.
Fixes #14498.
When a topic is moved to a different stream, the message may no
longer be reachable to guest user, if the user is not subscribed
to the new stream.

We used to send message update event to the client in these cases,
which seems to be confusing both to the client updating the message
and the server sending push_notifications for it.

Now, we delete the UserMessage entry for these messages for the
user and send a delete message event to the client; which makes
both push_notification and the event handling client think that
the message was deleted and hence no confusion in the code is
raised.

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 8d2d64c100 CVE-2020-14215: Fix validation in PreregistrationUser queries.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.

Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident.  But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.

The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.

Sara Gulotta 1cb040647b markdown: Add support for spoilers.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.

We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.

Fixes #5802.

Hashir Sarwar ecd35b9565 push_notifications: Add support for setting counts in iOS.
This adds a new function `get_apns_badge_count()` to

sahil839 791e5de5de api: Remove is_old_stream property from the stream objects.
This commit removes is_old_stream property from the stream objects
returned by the API. This property was unnecessary and is essentially
equivalent to 'stream_weekly_traffic != null'.

in frontend code and it is used to check whether we have a non-null
stream_weekly_traffic or not.

Fixes #15181.

Tim Abbott 5b49839b08 bankruptcy: Clear mobile push notifications first.
This likely fix a bug that can leak thousands of messages into the
invalid state where:
* user_message.flags.active_mobile_push_notification is True
* user_message.flags.read is True

which is intended to be impossible except during the transient process
between marking messages as read sending the "remove push
notifications" event.

The bug is that if a user who is declaring bankruptcy with 10,000s of
unreads ends up having the database query to mark all of those as read
take 60s, the Django/uwsgi request will time out and kill the process.
If the postgres transaction still completes, we'll end up with the
second half of this function never being run.

A safer ordering is to do the smaller queries first.

We do this in a loop for correctness in the unlikely event there are
more than 10,000 of these.

arpit551 c4b5d09283 analytics: Add LoggingCount for messages read stats.
Whenever we use API queries to mark messages as read we now increment
two new LoggingCount stats, messages_read::hour and
messages_read_interactions::hour.

We add an early return in do_increment_logging_stat function if there
are no changes (increment is 0), as an optimization to avoid
unnecessary database queries.

We also log messages_read_interactions::hour Logging stat
as the number of API queries to mark messages as read.

We don't include tests for the case where do_update_pointer is called
because do_update_pointer will most likely be removed from the
codebase in the near future.

Anders Kaseorg 69c0959f34 python: Fix misuse of Optional types for optional parameters.
There seems to have been a confusion between two different uses of the
word “optional”:

• An optional parameter may be omitted and replaced with a default
  value.
• An Optional type has None as a possible value.

Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type.  But in
other cases, optional parameters should not have Optional type.  Fix
them.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of

Graham Bleaney 461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

Steve Howell d5cc29755e typing: Accept only user_ids in typing endpoint.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.

We now enforce this, which removes some
complexity surrounding legacy ways of sending
users, such as emails and comma-delimited
strings of user_ids.

There may be a very tiny number of mobile
clients that still use the old emails API.

This won't have any user-facing effect on
the mobile users themselves, but if you type
a message to your friend on an old mobile
app, the friend will no longer see typing
indicators.

Also, the mobile team may see some errors
in their Sentry logs from the server rejecting
posts from the old mobile clients.

The error messages we report here are a bit
more generic, since we now just use REQ
to do validation with this code:

    validator=check_list(check_int)

This also allows us to remove a test hack
related to the API documentation.  (We changed
the docs to reflect the modern API in an
earlier commit, but the tests couldn't be
fixed while we still had the more complex
semantics for the "to" parameter.)
