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).
If the caller has already fetched the Stream or subscription details
for the user, those can be passed to has_message_access to avoid extra
database queries.
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.
This makes it parallel with deliver_scheduled_messages, and clarifies
that it is not used for simply sending outgoing emails (e.g. the
`email_senders` queue).
This also renames the supervisor job to match.
The screenshot generating mechanism doesn't work for newrelic and

A message containing wildcard mention when quoted (which
is turned into a silent mention) or message with silent
wildcard mention notifies the users by sending desktop,
sound, and missed message email notifications. This
is clearly a bug which is fixed by this commit.
Fixes: #18354.
Note that the documentation cannot fully use our macros, because
Uptime Robot requires an & of the end of the URL, because of how it
passes its payload.
Fixes#13854. Fixes#13939.
We combine the two loops into one, so that we
can check our flags before creating the
UserMessageList object.
And we lift a few calculations out of the loop.
For 8k users, with 95% long-term-idle, this was
about a 10x speedup for me. (~30ms -> 3ms)
Support for the timeouts, and tests for them, was added in
53a8b2ac87 -- though no code could have set them after 31597cf33e.
Add a 10-second default timeout. Observationally, p99 is just about
5s, with everything else being previously being destined to meet the
30s worker timeout; 10s provides a sizable buffer between them.

Move `get_setup_webhook_message` to

Django's default SMTP implementation can raise various exceptions
when trying to send an email. In order to allow Zulip calling code
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.

In Django 3.2 slugify strips trailing dashes and underscores:
0382ecfe02
sanitize_name doesn't so this difference should be documented like the
others.
Underscore character is already covered by \w, so _ in the regex is
redundant. Also the docstring is mildly incorrect - underscore already
is an allowed character by django's slugify (and always was) for the
aforementioned reason.
Now that we are passing source realm's id instead of string_id in
source realm selector, it makes sense to rename the "source_realm" field
to "source_realm_id".
In the source realm selector, when we select a realm from which we want
to import the data, we pass the source realm's string_id. The problem
with this approach is that the string_id can be an empty string. This
commit makes the source_realm pass the realm's id instead of string_id.
Now, the source_realm's value will either be an integer or "" (empty
string) when we don't want to import settings from any realm.
The function get_role_for_new_user was added to get role from the
invited_as value, as invited_as values were one of (1,2,3,4)
previously, but it was then changed to be the actual role value,
i.e. one of (100, 200, 400, 600), in 1f8f227444.
So, we can safely remove this function now and use invited_as value
directly and handle realm_creation case by using an if condition.

Fixes: #18205.
Event of type restart could not be handled properly, because of
its special behavior. For handling this event in most natural way
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.
Fixes: #15541.
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.
This allows access to be more configurable than just setting one
attribute. This can be configured by setting the setting
AUTH_LDAP_ADVANCED_REALM_ACCESS_CONTROL.
This change is made to comply with the corresponding views for
the API. The incrementor implementation in zulip_bots won't work
otherwise if send_message and send_reply return None as it needs
the message id.
This commit create a directory to store the mock message for nagios and
more will be added.
The json files in this directory will be used to config the screenshot
generating script for the documentations of non-webhook integrations.
This extends the /json/typing endpoint to also accept
stream_id and topic. With this change, the requests
sent to /json/typing should have these:
* `to`: a list set to
- recipients for a PM
- stream_id for a stream message
* `topic`, in case of stream message
along with `op`(start or stop).
On receiving a request with stream_id and topic, we send
typing events to clients with stream_typing_notifications set
to True for all users subscribed to that stream.
The comment explains in more detail, but this should help avoid cases
where a Zulip server accidentally avoids the nag by having upgraded to
a 2-year old Zulip version from a 3-year-old version 2 months ago.
Add a `--dry-run` flag to send_custom_email management command
in order to provide a mechanism to verify the emails of the recipients
and the text of the email being sent before actually sending them.
Add tests to:
- Check that no emails are actually sent when we are in the dry-run mode.
- Check if the emails are printed correctly when we are in the dry-run mode.
Fixes#17767
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.

It's better to just raise JsonableError here, as that makes this error
processed in the central place for this kind of thing in do_rest_call:
---------
except JsonableError as e:
response_message = e.msg
logging.info("Outhook trigger failed:", stack_info=True)
fail_with_message(event, response_message)
response_message = f"The outgoing webhook server attempted to send a message in Zulip, but that request resulted in the following error:\n> {e}"
notify_bot_owner(event, failure_message=response_message)
return None
----------
which does all the things that are supposed to happen -
fail_with_message, appropriate logging and notifying the bot owner.
Remove content edit keys if present in edit_history_event
when passing to update_messages_for_topic_edit.
Since content edit is only applied to the edited_message,
this shouldn't be part of the rest of the messages for which
topic was edited. This was a bug identified by
editing topic and content of a message at the same time
when more than 1 message is affected.
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)
There exists a logic bug (see #18236) which causes duplicate
usermessage rows to be inserted. Currently, this stops catch-up for
all users.
Catch and record the exception for each affected user, so we at least
make catch-up progress on other users.
This was a mostly harmless bug, since those users cannot have active
clients, but fixing it will improve performance in any Zulip
organization where the vast majority of users are deactivated.
This commit adds an API to `zproject/urls.py` to edit/update
the realm linkifier. Its helper function to update the
database is added in `zerver/lib/actions.py`.
`zulip.yaml` is documented accordingly as well, clearly
stating that this API updates one linkifier at a time.
The tests are added for the API and helper function which
updates the realm linkifier.
Fixes#10830.
The caller is supposed validate the stream and user realm match, but
since this is a security-sensitive function, we should have this
defensive code to protect against some validation bugs in the caller
leading to this being called incorrectly and returning True.
Fixes#17922.
These two places fetch subscriptions for the sake of getting user ids to
send events to. Clearly deactivated users should be excluded from that.
get_active_subscriptions_for_stream_id should allow specifying whether
subscriptions of deactivated users should be included in the result.
Active subs of deactivated users are a subtlety that's easy to miss
when writing relevant code, so we make include_deactivated_users a
mandatory kwarg - this will force callers to definitely give thought to
whether such subs should be included or not.
This commit is just a refactoring, we keep original behavior everywhere
- there are places where subs of deactivates users should probably be
excluded but aren't - we don't fix that here, it'll be addressed in
follow-up commits.
The bulk deletion codepath was using dicts instead of user ids in the
event, as opposed to the other codepath which was adjusted to pass just
user ids before. We make the bulk codepath consistent with the other
one. Due to the dict-type events happening in 3.*, we move the goal for
deleting the compat code in process_notification to 5.0.

I have added a documentation page for the GitHub Actions integration to
`/integrations/doc/github-actions` with a link to the Zulip GitHub
Actions repository.
Tweaked by tabbott to add cross-links with the main GitHub integration.
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.
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.

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.
* 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.
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.
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.
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.
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.
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`.
Commit 4a3ad0d introduced some extra stream-level parameters
to the `realm` object. This commit extends that to add a
max_message_length paramter too in the same server_level.
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.
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.
Instead of using internal functions for data setup,
we use the API so that these tests are more
end-to-end.
This commit also removes a now unnecessary
`if date_muted is None` check.
We keep the error message same for all cases when a user is not
allowed to create streams for all values of create_stream_policy.
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.
This makes it much more clear that this feature does JSON encoding,
which previously was only indicated in the documentation.

settings overlay in the next commit.
We add moderators and full members option to invite_to_realm_policy
by using COMMON_POLICY_TYPES and use can_invite_others_to_realm helper
