Tim Abbott af2b1ef3a1 page_params: Remove duplicate debug_mode field.
This had the same value as development_environment, I believe in a way
likely to persist long term, and was less clear about its meaning.

Tim Abbott 2e67b879ed api: Add server_timestamp to register response.
Since this is currently only useful to interpret presence data, we
send this only if presence is requested.

I'm not sure that server_timestamp is the right name for this field,
but ultimately it should match the main presence API format.

Abhijeet Prasad Bodas d6871dbae5 message send: Do not re-assign widget_content variable.
After re-assignment, mypy will still think the type of

akshatdalton f56fca308a mention: Refactor `USER_GROUP_MENTIONS_RE` and simplify its related code path.
Earlier, USER_GROUP_MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(\*[^\*]+\*)"

For the syntax: *foo*, this was unnecessarily capturing it as
*foo* and the extraction of `foo` was done using another helper
function: `extract_user_group`.

This is now changed as:
r"(?<![^\s\'\"\(,:<])@(\*(?P<match>[^\*]+)\*)"

and extraction of `foo` can be done just by using the named capture
group `match`.

This change also helps to simplify its related code path.

Earlier, MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(?P<match>\*\*[^\*]+\*\*)"

For the syntax: **foo**, this was unnecessarily capturing it as
**foo** and adding extra operation for the extraction of `foo`.

This is now changed as:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(\*\*(?P<match>[^\*]+)\*\*)"

and extraction of `foo` can be done just by using the named capture

sahil839 213eda1f32 message: Check stream_post_policy when moving messages between streams.
Previously only admins were allowed to move messages between streams
and admins are allowed to post in any stream irresepctive of stream
post policy, so there was no need to check for stream post policy.

But as we now allow other members to also move messages, we need
to check whether the user who is moving the message is allowed
to post to the target stream (i.e. stream to which the messages
are being moved) and thus we allow moving messages only if the
user is allowed to post in target stream.

Mateusz Mandera de6bd22ee9 outgoing_webhook: Treat "" json in response as response_not_required.
b7b1ec0aeb made our checks of the response
format stronger, to enforce that the json translates to a valid dict.
However, old client code (zulip_botserver) was using "" as equivalent to
response_not_required - so we need to keep backward-compatibility to not
break things built on it.

Tim Abbott 41d499d44c message_edit: Require access to messages to move between streams.
Currently, moving messages between streams is an action limited to
organization administrators. A big part of the motivation for that
restriction was to prevent users from moving messages from a private
stream without shared history as a way to access messages they should
not have access to.

Organization administrators can already just make the stream have
shared history if they want to access its messages, but allowing
non-administrators to move messages between would have
introduced a security bug without this change.

Steve Howell b4470ac8e1 performance: Add get_subscriptions_for_send_message.
This new function optimizes how we fetch subscriptions
for streams.  Basically, it excludes most long-term-idle
users from the query.

With 8k users, of which all but 400 are long term idle,
this speeds up get_recipient_info from about 150ms
to 50ms.

Overall this change appears to save a factor of 2-3 in the backend
processing time for sending or editing a message in large, public
streams in chat.zulip.org (at 18K users today).

Mateusz Mandera c95cac2dd7 outgoing_webhook: Send response payload to bot owner if it was invalid.
When the format of the response received from the outgoing webhook
server is invalid (unparsable json, or just wrong format that doesn't
translate into a dictionary etc.), a message with the error is sent to
the bot owner. We should include the actual payload to make reasonable
debugging possible.

In notify_bot_owner we have to move the `if response_content` block to
append the payload to the message whenever it was specified as an
argument to the function. It shouldn't be nested inside
`elif status_code` as before.

Cyril Pletinckx e4ff372fc3 emails: Transform SMTPException into EmailNotDeliveredException.
Django's default SMTP implementation can raise various exceptions

to catch fewer exceptions to handle any cause of "email not
sent", we translate most of them into EmailNotDeliveredException.
The non-translated exceptions concern the connection with the
SMTP server. They were not merged with the rest to keep some
details about the nature of these.

Tests are implemented in the test_send_email.py module.

Ganesh Pawar ddf2127035 widgets: Prevent edits to widgets.
As of now, editing a widget doesn't update the rendered content.
It's important to ensure that existing votes or options added later on
don't get deleted when rendered.
This seems more complex than it's worth.

For now, we just prevent edits to widgets.
This commit makes the UI clearer that editing widgets isn't allowed.

Event of type restart could not be handled properly, because of

we recursively call `do_events_register` when restart event is
recieved, based on custom error created for this event.

Testing: Second call to get_user_events due to recursive calling
of do_event_register, is expected to not contain the restart event.
So new test added in test_event_system.py are based on above behavior
of get_user_events.

pletinckxc 184df7e656 emails: Fix outgoing email handling inside the dev environment.
Commit 9afde790c6 introduced a bug
concerning outgoing emails inside the development environment. These
emails are not supposed to use a real connection with a mail
server as the send_messages function is overwritten inside the
EmailLogBackEnd class.

The bug was happening inside the initialize_connection function that
was introduced in the above-mentioned commit. This function is used
to refresh the connection with an SMTP server that would have closed
it. As the socket used to communicate with the server is not
initialized inside the development environment this function was
wrongly trying to send no-op commands.

The fix just checks that the connection argument of the function is
an EmailLogBackEnd object before trying the no-op command.
Additionally as it is sometimes useful to be able to send outgoing
emails inside the development environment the get_forward_address
function is used to check if a real connection exists between Zulip
and the server. If it is the case, as EmailLogBackEnd is a subclass
of smtp.EmailBackend, the connection will be nicely refreshed.

This commit was tested manually by checking that the console prints
correctly that an email is sent to the user when it signs in inside
the development environment. It was also tested when a mail provider
is specified and the mails were correctly received.

Cyril Pletinckx 9afde790c6 email: Open a single SMTP connection to send email batches.
Previously the outgoing emails were sent over several SMTP
connections through the EmailSendingWorker; establishing a new
connection each time adds notable overhead.

Redefine EmailSendingWorker worker to be a LoopQueueProcessingWorker,
which allows it to handle batches of events. At the same time, persist
the connection across email sending, if possible.

The connection is initialized in the constructor of the worker
in order to keep the same connection throughout the whole process.
The concrete implementation of the consume_batch function is simply
processing each email one at a time until they have all been sent.

In order to reuse the previously implemented decorator to retry
sending failures a new method that meets the decorator's required
arguments is declared inside the EmailSendingWorker class. This
allows to retry the sending process of a particular email inside
the batch if the caught exception leaves this process retriable.

A second retry mechanism is used inside the initialize_connection
function to redo the opening of the connection until it works or
until three attempts failed. For this purpose the backoff module
has been added to the dependencies and a test has been added to
ensure that this retry mechanism works well.

The connection is closed when the stop method is called.

Fixes: #17672.

Mateusz Mandera 1a8ad796f8 models: Replace __id syntax with _id where possible.
model__id syntax implies needing a JOIN on the model table to fetch the
id. That's usually redundant, because the first table in the query
simply has a 'model_id' column, so the id can be fetched directly.
Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.

The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
  y = models.ForeignKey(Y)

then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)

whether such subs should be included or not.

Mateusz Mandera 6e11754642 CVE-2021-30478: Prevent API super users from forging messages to other organizations.
A bug in the implementation of the can_forge_sender permission
(previously is_api_super_user) resulted in users with this permission
being able to send messages appearing as if sent by a system bots,
including to other organizations hosted by the same Zulip installation.

- The send message API had a bug allowing an api super user to
  use forging to send messages to other realms' streams, as a
  cross-realm bot. We fix this most directly by eliminating the
  realm_str parameter - it is not necessary for any valid current use
  case. The email gateway doesn't use this API despite the comment in
  that block suggesting otherwise.
- The conditionals inside access_stream_for_send_message are changed up
  to improve security. They were generally not ordered very well,
  allowing the function to successfully return due to very weak
  acceptance conditions - skipping the higher importance checks that
  should lead to raising an error.
- The query count in test_subs is decreased because
  access_stream_for_send_message returns earlier when doing its check
  for a cross-realm bot sender - some subscription checking queries are
  skipped.
- A linkifier test in test_message_dict needs to be changed. It didn't
  make much sense in the first place, because it was creating a message
  by a normal user, to a stream outside of the user's realm. That
  shouldn't even be allowed.

Mateusz Mandera 4235be759d CVE-2021-30477: Prevent outgoing webhook bots from sending arbitrary messages to any stream.
A bug in the implementation of replies to messages sent by outgoing
webhooks to private streams meant that an outgoing webhook bot could be
used to send messages to private streams that the user was not intended
to be able to send messages to.

Completely skipping stream access check in check_message whenever the
sender is an outgoing webhook bot is insecure, as it might allow someone
with access to the bot's API key to send arbitrary messages to all
streams in the organization. The check is only meant to be bypassed in
send_response_message, where the stream message is only being sent
because someone mentioned the bot in that stream (and thus the bot
posting there is the desired outcome). We get much better control over
what's going by passing an explicit argument to check_message when
skipping the access check is desirable.

Tim Abbott 9f57961e5f stream_subscription: Remove opaque reference to guest role. 2021-04-13 21:49:57 -07:00
sahil839 685fbffd91 tests: Refactor check_has_permission_policies to check for all user roles.
We refactor check_has_permission_policies to check for all user roles for
each value of policy. This will help in handle a case where a guest is
allowed to do something but moderator isn't.

We need to do user_profile.refresh_from_db() in validation_func because
the realm object from user_profile is used in has_permission and we need
updated realm instance after changing the policy.

This is a follow-up commit to 9a4c58cb.

Abhijeet Prasad Bodas 3947b0c80a linkifiers: Update API to send data using dictionaries.
* This introduces a new event type `realm_linkifiers` and
a new key for the initial data fetch of the same name.
Newer clients will be expected to use these.

* Backwards compatibility is ensured by changing neither
the current event nor the /register key. The data which
these hold is the same as before, but internally, it is
generated by processing the `realm_linkifiers` data.
We send both the old and the new event types to clients
whenever the linkifiers are changed.
Older clients will simply ignore the new event type, and
vice versa.

* The `realm/filters:GET` endpoint (which returns tuples)
is currently used by none of the official Zulip clients.
This commit replaces it with `realm/linkifiers:GET` which
returns data in the new dictionary format.
TODO: Update the `get_realm_filters` method in the API
bindings, to hit this new URL instead of the old one.

* This also updates the webapp frontend to use the newer
events and keys.

Tim Abbott 2e928a0853 markdown: Remove logic for creating markdown engines for all realms.
This logic likely never ran due to a combination of bugs.

* Running `maybe_update_markdown_engines` unconditionally meant that
  `if md_engine_key in md_engines` was likely always true.
* Introduced in 65838bb: DEFAULT_MARKDOWN_KEY could never be in
  md_engines, so should we have ever reached that code path, we'd have
  tried to rebuild all markdown engines every time.

And it also wasn't clearly helpful -- because we fetch all linkifiers
for a realm on every request anyway, we don't really save database
queries by doing a bulk fetch on startup, and doing so would likely
result in a material regression to Zulip's overall startup time that
we were creating markdown engines for large numbers of realms in bulk
during process startup.

Abhijeet Prasad Bodas 2b9f2cc8ff mute user: Add some comments on message fetch.
These explain why we don't consider user mutes
in message fetching/unread data.
2021-04-13 09:15:49 -07:00
Abhijeet Prasad Bodas 8b098b95bb mute user: Mark as read old messages immediately.
When a user is muted, in the same request,
we mark any existing unreads from that user
as read.

This is done for all types of messages
(PM/huddle/stream) and regardless of whether
the user was mentioned in them.

This will not break the unread count logic
of the web frontend, because that algorithm
decides which messages to mark as read based
only on the pointer location and the whitespace
at the bottom, not on what messages have already
been marked as read.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas 2f56f8d0ed mute user: Mark as read new messages.
Messages sent by muted users are marked as read
as soon as they are sent (or, more accurately,
while creating the database entries itself), regardless
of type (stream/huddle/PM).

ede73ee4cd, makes it easy to
pass a list to `do_send_messages` containing user-ids for
whom the message should be marked as read.
We add the contents of this list to the set of muter IDs,
and then pass it on to `create_user_messages`.

This benefits from the caching behaviour of `get_muting_users`
and should not cause performance issues long term.

The consequence is that messages sent by muted users will
not contribute to unread counts and notifications.

This commit does not affect the unread messages
(if any) present just before muting, but only handles
subsequent messages. Old unreads will be handled in
further commits.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas b140c17441 mute user: Cache list of muter IDs.
This commit defines a new function `get_muting_users`
which will return a list of IDs of users who have muted
a given user.
Whenever someone mutes/unmutes  a user, the cache will be
flushed, and subsequently when that user sends a message,
the cache will be populated with the list of people who
have muted them (maybe empty).

This data is a good candidate for caching because-

1. The function will later be called from the message send
codepath, and we try to minimize database queries there.

2. The entries will be pretty tiny.

3. The entries won't churn too much. An average user will
send messages much more frequently than get muted/unmuted,
and the first time penalty of hitting the db and populating
the cache should ideally get amortized by avoiding several
DB lookups on subsequent message sends.

The actual code to call this function will be written in
further commits.
2021-04-13 09:08:47 -07:00
Abhijeet Prasad Bodas 9602aa1467 mute user: Record entries in RealmAuditLog.
This makes it so that RealmAuditLog entries are
created when a user mutes/unmutes someone.

We don't really need to store the time, but we
do so anyways, because the `event_time` field
is currently a non-nullable one in the `RealmAuditLog`
model, and making it nullable would risk allowing
not specifying the time in other more important
code which also creates `RealmAuditLog` entries.

This also fixes an incorrect test of successfully
unmuting with the API. Earlier it did not mock
the time in the `views/muting.py` code to return
`mute_time`.

api: Add max_message_length field to API data.
Commit 4a3ad0d introduced some extra stream-level parameters

2021-04-12 16:03:31 -07:00
Tim Abbott 4a3ad0da06 api: Improve encoding of stream/topic max field lengths.
Previously, you had to request the `stream` event type in order to get
the stream-level parameters; this was a bad design in part because the
`subscription` event type has similar data and is preferred by most
clients.

So we move these to the `realm` object.  We also add the maximum topic
length, as an adjacent parameter.

While changing this, we also fix these to better match the names of
similar API parameters.

Abhijeet Prasad Bodas 152508e346 mute user: Reduce two database fetches when unmuting to one.
Previously, when unmuting a user, we used to make
two database fetches - one to verify that the user
is has been muted before, and one while actually
unmuting the user.

This reduces that to one, by passing around the
`MutedUser` object fetched in the first round.

Since the new function returns `Optional[MutedUser]`,
we need to use a hack for events tests, because
mypy does not yet use the type inferred from
`assert foo is not None` in nested functions like lambdas.
See python/mypy@8780d45507.

sahil839 1ffcb0f8b9 streams: Raise same error for all values of create_stream_policy.
We keep the error message same for all cases when a user is not

We raise error with different message for guest cases because it
is handled by decorators. We aim to change this behavior in future.

Explaining the details in error message isn't much important as
we do not show errors probably in API only, as we do not the show
the options itself in the frontend.

Sumanth V Rao 1ac8fe7538 events/tests/api: Send realm_playground events to clients.
We send the whole data set as a part of the event rather than
doing an add/remove operation for couple of reasons:
    * This would make the client logic simpler.
    * The playground data is small enough for us to not worry
      about performance.

Tweaked both `fetch_initial_state_data` and `apply_events` to
handle the new playground event.

Tests added to validate the event matches the expected schema.

Documented realm_playgrounds sections inside /events and
/register to support our openapi validation system in test_events.

Tweaked other tests like test_event_system.py and test_home.py
to account for the new event being generated.

Lastly, documented the changes to the API endpoints in

of the structure in how notify_reaction_update only looked at

Cyril Pletinckx b7fa41601d emails: Truncate overly-long From fields for RFC compatibility.
Amazon SES has a limit on the size of address fields, and rejects
emails with too-long "From" combinations of name and address. This
limit is set to 320 bytes and comes from an RFC limitation on the
size of addresses. This RFC standard states that an email address
should not be composed of a local part (before the '@') longer than
64 bytes and a domain part (after the '@') longer than 255 bytes.
It is possible that Amazon SES misinterprets this limitation as it
checks the length of the combination of the name and the email
address of the sender.

To ensure that this problem is not encountered in the send_email
module of Zulip the length of this combination is now checked
against this limit and the from_name field is removed to only
keep the from_address field when it is necessary in order to
stay below 320 bytes.

If the from_address field alone is longer than 320 bytes the
sending process will raise an SMTPDataError exception.

Tests for this new check are added to the backend test suite in
order to test if build_email correctly outputs an email with filled
from_name and from_address fields when the total length is lower
than 320 bytes and that it correctly throws the from_name field
away when necessary.

Fixes: #17558.
