Prakhar Pratyush 68abc6af21 unread_msgs: Fix 'raw_unread_messages["muted_stream_ids"]' not set.
The raw_unread_messages["muted_stream_ids"] was not properly
updated with the calculated value.

The bug was introduced in 72e0084692.

Prakhar Pratyush 49092dfa79 unread_msgs: Fix all unreads in muted stream being treated as muted.
Earlier, 'is_row_muted' returned 'true' if the message was in
a muted stream or muted topic.

If the message is in an unmuted or followed topic in a muted
stream, such topics should be treated as not muted topics
in an unmuted stream.

This commit fixes the incorrect behavior.

Now, for wildcard mentions, 'unread_msgs.mentions' exclude
the IDs in muted streams only if the message is in default or
muted topic.

Also, 'unread_msgs.count' takes into account the unreads in unmuted
or followed topics in muted streams too.

Documents that this bug was fixed in the API changelog.

Prakhar Pratyush a18a526427 muted_stream_ids: Use set for O(1) search operation.
Update 'get_muted_stream_ids' to return a set of IDs
instead of a list.

This will help to avoid linear time search operations later
while using 'if stream_id in muted_streams_ids'.

Prakhar Pratyush faa98317bc user_topics: Refactor build_topic_mute_checker to support each policy.
This prep commit renames the 'build_topic_mute_checker' function
to 'build_get_topic_visibility_policy' and updates it to support
all the visibility policies.

The function prefetches the visibility policies the user has
configured for various topics and prepares a dict named
'topic_to_visibility_policy' to be used later on.

Alex Vandiver ae822103a7 message: Add realm limit to private-message summary query.
This query has two halves; messages set by the user, and messages
received by the user.  The former uses the already-specific
usermessage privatemessage flag index; the latter relies on the
recipient index on messages.

Add the realm_id to the latter half, so that the recipient_id is
paired with the realm_id.

Mateusz Mandera f3a3047484 bulk_access_messages_expect_usermessage: Fix function name and comments.
The name and docstring were just wrong, having a UserMessage row isn't
sufficient for having message access and is actually only relevant in a
private stream with private history. The function is only used in a
single place anyway, in bulk_access_messages.

The comment mentioning this function in handle_remove_push_notification
can be tweaked to just not mention any function specifically and just
say why we're not checking message access.

Mateusz Mandera c908b518ef CVE-2023-32678: Prevent unauthorized editing/deletion in priv streams.
Users who used to be subscribed to a private stream and have been
removed from it since retain the ability to edit messages/topics, and
delete messages that they used to have access to, if other relevant
organization permissions allow these actions. For example, a user may be
able to edit or delete their old messages they posted in such a private
stream. An administrator will be able to delete old messages (that they
had access to) from the private stream.

We fix this by fixing the logic in has_message_access (which lies at the
core of our message access checks - access_message() and
bulk_access_messages())
to not rely on only a UserMessage row for checking access but also
verify stream type and subscription status.

Sahil Batra 7295028194 message: Access realm object directly from message.
We can directly get the realm object from Message object now
and there is no need to get the realm object from "sender"
field of Message object.

After this change, we would not need to fetch "sender__realm"
field using "select_related" and instead only passing "realm"
to select_related when querying Message objects would be enough.

This commit also updates a couple of cases to directly access
realm ID from message object and not message.sender. Although
we have fetched sender object already, so accessing realm_id
from message directly or from message.sender should not matter,
but we can be consistent to directly get realm from Message
object whenever possible.

Prakhar Pratyush 379a08eb1e message_send: Fix wildcard_mentioned flag unset for few participants.
For topic wildcard mentions, the 'wildcard_mentioned' flag is set
for those user messages having 'user_profile_id' in
'topic_participant_user_ids', i.e. all topic participants.

Earlier, the flag was set if the 'user_profile_id' exists in
'all_topic_wildcard_mention_user_ids'.
'all_topic_wildcard_mention_user_ids' contains the ids of those
users who are topic participants and have enabled notifications
for '@topic' mentions.

The earlier approach was incorrect, as it would set the
'wildcard_mentioned' flag only for those topic participants
who have enabled the notifications for '@topic' mention instead
of setting the flag for all the topic participants.

The bug was introduced in 4c9d26c.

Prakhar Pratyush 179d5cb37d mention: Replace 'wildcards' with 'stream_wildcards'.
This prep commit replaces the 'wildcard' keyword in the codebase
with 'stream_wildcard' at some places for better readability, as
we plan to introduce 'topic_wildcards' as a part of the
'@topic mention' project.

Currently, 'wildcards = ["all", "everyone", "stream"]' which is an
alias to mention everyone in the stream, hence better renamed as
'stream_wildcards'.

Eventually, we will have:
'stream_wildcard' as an alias to mention everyone in the stream.
'topic_wildcard' as an alias to mention everyone in the topic.
'wildcard' refers to 'stream_wildcard' and 'topic_wildcard' as a whole.

Sahil Batra 0ed5f76063 settings: Add backend code for using user email_address_visibility setting.
This commits update the code to use user-level email_address_visibility
setting instead of realm-level to set or update the value of UserProfile.email
field and to send the emails to clients.

Major changes are -

- UserProfile.email field is set while creating the user according to
RealmUserDefault.email_address_visbility.

- UserProfile.email field is updated according to change in the setting.

- 'email_address_visibility' is added to person objects in user add event
and in avatar change event.

- client_gravatar can be different for different users when computing
avatar_url for messages and user objects since email available to clients
is dependent on user-level setting.

- For bots, email_address_visibility is set to EVERYONE while creating
them irrespective of realm-default value.

- Test changes are basically setting user-level setting instead of realm
setting and modifying the checks accordingly.

Prakhar Pratyush 1a400b21e7 notifications: Fix missed message email notifications of welcome bot.
A missed message email notification, where the message is the welcome
message sent by the welcome bot on account creation, get sent when
the user somehow not focuses the browser tab during account creation.

No missed message email or push notifications should be sent for the
messages generated by the welcome bot.

'internal_send_private_message' accepts a parameter
'disable_external_notifications' and is set to 'True' when the sender
is 'welcome bot'.

A check is introduced in `trivially_should_not_notify`, not to notify
if `disable_external_notifications` is true.

TestCases are updated to include the `disable_external_notifications`
check in the early (False) return patterns of `is_push_notifiable` and
`is_email_notifiable`.

One query reduced for both `test_create_user_with_multiple_streams`
and `test_register`.
Reason: When welcome bot sends message after user creation
`do_send_messages` calls `get_active_presence_idle_user_ids`,
`user_ids` in `get_active_presence_idle_user_ids` remains empty if
`disable_external_notifications` is true because `is_notifiable` returns
false.
`get_active_presence_idle_user_ids` calls `filter_presence_idle_user_ids`
and since the `user_ids` is empty, the query inside the function doesn't
get executed.

MissedMessageHookTest updated.

Mateusz Mandera 89d1f1f385 messages: Eliminate redundant realm fetch in has_message_access.
Accessing .realm will cause a fetch query from the database if the
attribute hasn't been fetched already earlier in the codepath. That's
completely redundant if we're just comparing realms, and we should only
access .realm_id attribute. This seems to eliminate a query in some
codepaths, which is nice in this performance-sensitive function.

Similarily, we should have `Iterable[T]` instead of `List[T]` so that

Alex Vandiver 351bdfaf78 preview: Use cache only as a non-durable cache, not an IPC.
The `get_link_embed_data` / `link_embed_data_from_cache` pair as
introduced in c93f1d4eda uses the cache
as a temporary store inside of the `embed_links` worker; this means
that it must be durable storage, or the worker will stall and re-fetch
the same links to preview them.

Switch to plumbing through the fetched URL embed data as an parameter
to the Markdown evaluation which uses them, rather than using the
cache as an intermediary.  This frees up the cache to be merely a
non-durable cache.

As a side-effect, this removes get_cache_with_key, and
link_embed_data_from_cache which was its only callsite.

Tim Abbott 1a46df40c3 resolve topic: Limit unread flag on automated notifications.
Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.

We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.

Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.

Fixes #19709.

sahil839 b13bfa09c5 message: Make zero invalid value for message_content_delete_limit_seconds.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.

Steve Howell 45f6c8d27f page load: Remove sender_ids in unread messages for streams. 2021-08-04 11:44:00 -04:00
Abhijeet Prasad Bodas de04f0ad67 notifications: Calculate PMs/mentions settings like other settings.
Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:

1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
    return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.

Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)

then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.

The buggy code was this in `handle_push_notifications`:
```
if not (
    receives_offline_push_notifications(user_profile)
    or receives_online_push_notifications(user_profile)
):
    return

    // send notifications
```

This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.

2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).

3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.

Riken Shah a96c614420 message: Fix the edit topic bug by removing leading \n from msg content.
The reason for this bug is because of different striping
processes in the backend and frontend, i.e The frontend
checks if the message's `raw_content` has changed to
decide if the `content` of the message should be sent in
the request to the backend, or not. So, it removes the
leading new line ('\n') from the message `raw_content`
when checking it, which is causing the "Error saving edit:
You don't have permission to edit this message" error.

This commit fixes it by removing the leading new line
when cleaning message content.

The bug was explained by @punchagan and its solution
by @timabbott.

Abhijeet Prasad Bodas 5f4113cf60 message delete: Select Message FOR UPDATE when archiving.
Further commits will start locking the message rows while
adding related fields like reactions or submessages,
to handle races caused by deleting the message itself at the
same time.

The message locking implemented then will create a possibility
of deadlocks, where the related field transaction holds a lock
on the message row, and the message-delete transaction holds a
lock on the database row of the related field (which will also
need to be deleted when the message is deleted), and both
transactions wait for each other.

To prevent such a deadlock, we lock the message itself while
it is being deleted, so that the message-delete transaction
will have to wait till the other transaction (which is about
to delete the related field, and also holds a lock on the
message row) commits.

Abhijeet Prasad Bodas ddd123f133 message send: Rename `push_notify_user_ids` -> `online_push_user_ids`.
The old name `push_notify_user_ids` was misleading, because
it does not contain user ids which should be notified for
the current message, but rather user ids who have the online
push notifications setting enabled.

When the Tornado server is restarted during an upgrade, if
server has old events with the `push_notify_user_ids` fields,
the server will throw error after this rename. Hence, we need
to explicitly handle such cases while processing the event.

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)

Mateusz Mandera 90636d5e81 events: Fix bug in get_recent_conversations_recipient_id.
user_profile.id was confused for user_profile.recipient_id. These bugs
are particularly sneaky as they can go undetected by tests due to ids of
objects accidentally coinciding. We add a mitigation for this class of
mistakes by shifting the Recipient.id sequence in test db.

This was introduced in dda3ff41e1.
On the rare occasion where user_profile.id would coincide with
recipient_id passed to the function, we would return the wrong value.
That is, instead of correctly returning recipient_id, we would return
sender.recipient_id - recipient id of the sender of the message, thus
possibly returning user_profile.recipient_id (if user_profile is the
sender) - exactly the situation the function wanted to avoid
with the `if recipient_id == my_recipient_id:` if. Ultimately resulting
in incorrect/malformed data in
state['raw_recent_private_conversations'].

when using Dict.

SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.

Steve Howell c1f134a3a4 performance: Use ORM to fetch sender in render_markdown.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.

It's better to just let the ORM fetch this.  The
message object should already have sender.

The diff makes it look like we are saving round trips
to the database, which is true in some cases.  For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache.  The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).
