It is unnecessory to make use of `update_choice_delete_btn` since
we disable the dialog submit button in case no default streams
selected in Org settings > Default streams > Add stream.
This commit is a follow-up to PR: #22903
While editing select type profile field, if we submit empty or zero
choices it fails silently, current implementation for this issue does
not work for some cases, and this commit will fix that.
This will disable dialog submit button in case of empty field choices.
Also removing code of all calls making to `update_choice_delete_btn`
as that function have no more use-case for empty field choices, still
keeping the function because it gets used in `settings_streams.js`.

We now send stream creation and stream deletion events on
changing a user's role because a user can gain or lose
access to some streams on changing their role.
This commit extracts the code which queries the required streams
to a new function "get_user_streams". The new functions returns
the list of "Stream" object and not dictionaries and then
do_get_streams function converts it into list of dictionaries.
This change is important because we would use the new function
in further commit where we want list of "Stream" objects and
not list of dictionaries.
There was a bug in apply_event code where only a stream which
is not private is added to the "never_subscribed" data after
a stream creation event. Instead, it should be added to the
"never_subscribed" data irrespective of permission policy of
the stream as we already send stream creation events only to
those users who can access the stream. Due to the current
bug, private streams were not being added to "never_subscribed"
data in apply_event for admins as well. This commit fixes it
and also makes sure the "never_subscribed" list is sorted
which was not done before and was also a bug.
The bugs mentioned above were unnoticed as the tests did not
cover these cases and this commit also adds tests for those
cases.
The "streams" field in "/register" response did not include web-public
streams for non-admin users but the data for those are eventually
included in the subscriptions data sent using "subscriptions",
"unsubscribed" and "never_subscribed" fields.
This commit adds code to include the web-public streams in "streams"
field as well as everyone can access those and will make the "streams"
data complete.
This commit lets us render popovers centered on the screen with a
background overlay. It's the same thing we did with Bootstrap
popovers, but optimized for use with Tippy.
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.
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.
**Background**
User groups are expected to comply with the DAG constraint for the
many-to-many inter-group membership. The check for this constraint has
to be performed recursively so that we can find all direct and indirect
subgroups of the user group to be added.
This kind of check is vulnerable to phantom reads which is possible at
the default read committed isolation level because we cannot guarantee
that the check is still valid when we are adding the subgroups to the
user group.
**Solution**
To avoid having another transaction concurrently update one of the
to-be-subgroup after the recursive check is done, and before the subgroup
is added, we use SELECT FOR UPDATE to lock the user group rows.
The lock needs to be acquired before a group membership change is about
to occur before any check has been conducted.
Suppose that we are adding subgroup B to supergroup A, the locking protocol
is specified as follows:
1. Acquire a lock for B and all its direct and indirect subgroups.
2. Acquire a lock for A.
For the removal of user groups, we acquire a lock for the user group to
be removed with all its direct and indirect subgroups. This is the special
case A=B, which is still complaint with the protocol.
**Error handling**
We currently rely on Postgres' deadlock detection to abort transactions
and show an error for the users. In the future, we might need some
recovery mechanism or at least better error handling.
**Notes**
An important note is that we need to reuse the recursive CTE query that
finds the direct and indirect subgroups when applying the lock on the
rows. And the lock needs to be acquired the same way for the addition and
removal of direct subgroups.
User membership change (as opposed to user group membership) is not
affected. Read-only queries aren't either. The locks only protect
critical regions where the user group dependency graph might violate
the DAG constraint, where users are not participating.
**Testing**
We implement a transaction test case targeting some typical scenarios
when an internal server error is expected to happen (this means that the
user group view makes the correct decision to abort the transaction when
something goes wrong with locks).
To achieve this, we add a development view intended only for unit tests.
It has a global BARRIER that can be shared across threads, so that we
can synchronize them to consistently reproduce certain potential race
conditions prevented by the database locks.
The transaction test case lanuches pairs of threads initiating possibly
conflicting requests at the same time. The tests are set up such that exactly N
of them are expected to succeed with a certain error message (while we don't
know each one).
**Security notes**
get_recursive_subgroups_for_groups will no longer fetch user groups from
other realms. As a result, trying to add/remove a subgroup from another
realm results in a UserGroup not found error response.
We also implement subgroup-specific checks in has_user_group_access to
keep permission managing in a single place. Do note that the API
currently don't have a way to violate that check because we are only
checking the realm ID now.
We want to make the callers be more explicit about the use of the
user group being accessed, so that the later implemented database lock
can be benefited from the visibility.
Instead, we show a message with links that either opens a modal for
creating a new bot or navigates to the bot settings page. The
"add a new bot" link only show up when the user has enough permission
to create new bots, and the "manage your bots" link only shows up when
the user has at least one bot if they don't have the permission to
create one. Otherwise, the message does not show up at all.

This commit removes the 'View Edit History' option from the three-dot
menu since we have already implemented this feature through the
edited/moved label in the message. Therefore, we no longer need this
option in the three-dot menu. This commit aims to simplify the
three-dot message menu.
Fixes: #23077
This extraction has been done to make sure that creation of audio call
links can happen in the same function only.
A change in test was also required as the whole logic of finding the
textarea where the link should be inserted happens a bit later now.
The tabular figures in Source Sans 3 place a foot on the 1, and
overall just feel visually a little heavier than their proportional
counterparts.
To compensate for that, this takes advantage of the variable-font
properties of Source Sans 3 to subtly drop the weight to keep the
timestamp readable but not in fierce competition with the message
area.
In commit 640de3ad29, a separate
`page_params.ts` was added for the stats/analytics page, but adding
it to the `web/webpack.assets.json` for "stats" was missed, so we
add that here.
Updates the main description of the `api/set-typing-status` endpoint
for the new fields in the register response for the typing start,
stop, expired time intervals. Previously these were hardcoded by
the client side code and not the server side code.
Also updates the developer documentation for typing indicators in
the subsystems docs. This refreshes a few parts of that doc that
were already out of date, as well as adds the information about
the new register response fields noted above.
Adds typing notification constants to the response given by
`POST /register`. Until now, these were hardcoded by clients
based on the documentation for implementing typing notifications
in the main endpoint description for `api/set-typing-status`.
This change also reflects updating the web-app frontend code
to use the new constants from the register response.

The comment logic doesn’t make sense. Every build gets to write to
the caches; some builds do in fact add new items, and without
clean_unused_caches.py there’s no way for them to remove items.

Fixes#11767.
Previously multi-character emoji sequences weren't matched in the
emoji regex, so we'd convert the characters to separate images,
breaking the intended display.
This change allows us to match the full emoji sequence, and
therefore show the correct image.
This saves the blue box position as state on the location
in brower history, with `history.replaceState`.
The position is restored when a narrow is activated.
Fixes#20066.
