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.

Under the unicodedata distributed with Python 3.6, some Emoji are
classified as `Cn`, and not `So`:
```
$ unicode 1f929 --long
U+1F929 GRINNING FACE WITH STAR EYES
UTF-8: f0 9f a4 a9 UTF-16BE: d83edd29 Decimal: 🤩 Octal: \0374451
🤩
Category: So (Symbol, Other); East Asian width: W (wide)
Unicode block: 1F900..1F9FF; Supplemental Symbols and Pictographs
Bidi: ON (Other Neutrals)
$ python3.6 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
Cn
$ python3.7 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
So
```
Drop `Cn` from the list of excluded Unicode character classes, and
replace it with an explicit list of the 66 non-characters, which are
invariant.

An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.
Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.
This is a part of #20289.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
This commit adds code to check whether a user is allowed to use
wildcard mention in a large stream or not while editing a message
based on the realm settings.
Previously this was only checked while sending message, thus user
was easily able to use wildcard mention by first sending a normal
message and then using a wildcard mention by editing it.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.
`rendered_content` in historical messages may be empty; examining the
history of them may thus require diff'ing two empty strings, which
itself produces an empty string.
Use `lxml.html.fragment_fromstring` to be able to successfully parse
these, rather than 500.
Part of #19559.
Since the calls to the translation function `_()` are made outside
of the `send_message_moved_breadcrumbs` function, these strings are
translated outside of the `with override_language` block, leading to
translated strings even when we don't intend them to be translated.
We now use gettext_lazy with appropriate testing to avoid this.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.
This new setting has two options - everyone and admins only. Other
options including moderators will be added further.
We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.
Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.
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.
This adds a new class called MessageRenderingResult to contain the
additional properties we added to the Message object (like alert_words)
as well as the rendered content to ensure typesafe reference. No
behavioral change is made except changes in typing.
This is a preparatory change for adding django-stubs to the backend.

We already have this data in the `flags` for each user, so no need to
send this set/list in the event dictionary.
The `flags` in the event dict represent the after-message-update state,
so we can't avoid sending `prior_mention_user_ids`.
Previously, it was possible for an unusual series of topic-edit
actions to result in Notification Bot reporting that a topic was
marked as resolved that had already been marked as resolved, etc.
A buggy client might send a message_edit request to change the topic
field, sending the current topic as the new value. Previously, we
would treat that as a normal request to edit the topic; now we act as
though the API request had not requested a topic change. In the
common case that only the topic was in the edit request, this now
results in an error that should help client implementations identify
their bug.
This fixes a bad interaction with the "unresolve topic" logic, which
assumed that upstream logic had verified that the topic was actually
changing.
This is a prep commit for adding members, full members and moderator
options to edit_topic_policy. As we will be adding tests for these
options, we will need to add a login statment repeatedly and this
helps us in avoiding that.
This is a prep commit for adding moderators, full
members and member roles in edit_topic_policy.
As we add these new options, we will add tests with
user with all these roles and thus we would need to
login as iago repeatedly when changing parameters.
So, to avoid this we instead login as Iago in
set_message_editing_params itself.
This commit replaces the allow_community_topic_editing boolean with
integer field edit_topic_policy and includes both frontend and
backend changes.
We also update settings_ui.disable_sub_settings_onchange to not
change the color of label as we did previously when the setting
was a checkbox. But now as the setting is dropdown we keep the
label as it is and we don't do anything with label when disabling
dropdowns. Also, this function was used only here so we can safely
change this.
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.

This commit fixes a bug where moving messages between streams was
not allowed for non-admins when allow_community_topic_editing was
set to false and move_messages_between_streams_policy was set to
Realm.POLICY_MEMBERS_ONLY.
The bug is fixed by calling can_edit_content_or_topic only when
topic or content edit is there and not in the case where only
message is moved from one stream to another.
These checks are more related to the API than the editability
or permissions logic, so it makes sense to handle them first
before further processing the request.
Also split the main test class to separate out the tests for
this logic.
This also simplifies some tests by reducing the data setup
required to reach failure.
Tweaked by tabbott to avoid losing the topic_name.strip().
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.
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.
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.
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.

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.
This commit adds new helper can_move_messages_between_streams
which will be used to check whether a user is allowed to move
messages from one stream to another according to value of
'move_messages_between_streams_policy'.
This wasn't being validated before. There wasn't any possibility to
actually succeed in moving a private message, because the codepath would
fail at assert message.is_stream_message() in do_update_message - but we
should have proper error handling for that case instead of internal
server errors.
Otherwise an admin can move a topic from a private stream they're no
longer a part of - including the newest messages in the topic, that
they're not supposed to have access to.
A bug in the implementation of the topic moving API resulted in
organization administrators being able to move messages to streams they
shouldn't be allowed to - private streams they weren't subscribed to and
streams in other organization hosted by the same Zulip installation.
In our current model realm admins can't send messages to private streams
they're not subscribed to - and being able move messages to a
stream effectively allows to send messages to that stream and thus the
two need to be consistent.
