This commit adds an index for the query which the chat plugin executes
multiple times when preloading user data in `Chat::ChatChannelFetcher.unread_counts`.
Sample query plan from a query I grabbed from one of our production
instance.

* DEV: Skip push notifications for active online users
Currently, users with active push subscriptions get push notifications
regardless of their "presence" on the site.
This change introduces a `push_notification_time_window_mins`
site setting which is used in conjunction with a user's `last_seen_at` to
determine if push notifications should be sent. A user is considered to
be actively online if their `last_seen_at` is within `push_notification_time_window_mins`
minutes. `push_notification_time_window_mins` is set to 10 by default.
* DEV: Remove client param for push_notification_time_window_mins site setting

Use `Chat::ChatChannelFetcher.secured_public_channel_search` directly
checking for existence instead of running through
`Chat::ChatChannelFetcher.secured_public_channels` which executes 7 more
DB queries.
Follow up to a review in #18937, this commit changes the HashtagAutocompleteService to no longer use class variables to register hashtag data sources or types in context priority order. This is to address multisite concerns, where one site could e.g. have chat disabled and another might not. The filtered plugin registers I added will not be included if the plugin is disabled.
In both ChatMessage#rebake! and in ChatMessageProcessor
when we were calling ChatMessage.cook we were missing the
user_id to cook with, which causes missed hashtag cooks
because of missing permissions.
Previously, restricted category chat channel was available for all groups - even `readonly`. From now on, only user who belong to group with `create_post` or `full` permissions can access that chat channel.
* DEV: Remove enable_whispers site setting
Whispers are enabled as long as there is at least one group allowed to
whisper, see whispers_allowed_groups site setting.
* DEV: Always enable whispers for admins if at least one group is allowed.
We decided to rename the "Do Not Disturb" mode to "Pause Notifications". I am starting from changing strings on the client, that will update user interface. And I'm going to do renamings in frontend and backend code after some time.
This PR adds a new "Pause notifications" checkbox to the user status modal. This checkbox allows enabling the Do-Not-Disturb mode together with user status. Note that we don't remove and don't rename the existing DnD menu item in this PR, so the old way of entering the DnD mode is still available.
Also, we're not making DnD mode a part of user status on backend and in database. The reason is that the DnD mode should still be available on sites with disabled user status, having them separated helps keep the implementation simple.
This commit promotes all post_deploy migrations which existed in
Discourse v2.8.0 (timestamp <= 20220107014925).
This commit includes a fix to the promote_migrations script to promote
all migrations of the first version of the previous stable version. For
example, if the current stable version is v2.8.13, the version used as
a cutoff for promoting migrations is v2.8.0.
In #15474 we introduced dedicated support for date ranges. As part of that
change we added a fallback of "magic" date ranges, which treats dates in
any paragraph with exactly two dates as a range. There were discussions
about migrating all such paragraphs to use the new date range element, but
it was ultimately decided against.
This change removes the fallback and, as a bonus, adds support for multiple
date ranges in the same paragraph.
* FEATURE: Add support for desktop push notifications in core
Default to push for live notifications on desktop if available and
`enable_desktop_push_notifications` site setting set to true.
This removes the need for desktop-push-notifications plugin.
* DEV: Ensure live notifications are enabled explicitly
Allow a user with push notification access who has directly
enabled notifications via the browser settings to trigger push subscription
flow.
Way back in 90100378b8 when
we first added hashtag autocompletion, we added a rule to
say we should not trigger autocomplete when backspacing into
a hashtag. I think this is because we used to also not trigger
it at the start of the line because of how markdown headers
used to work. We removed this rule in 6f0b9bb1c4
so we are safe to remove the backspace exception here too.
Now you can backspace into a hashtag to trigger the autocomplete.
The autocomplete container has not needed to be
scrolled with arrow keys until we introduced the new
hashtag autocomplete, which shows more options and allows
scrolling. This commit scrolls the options up/down when
selecting an item outside the scroll with arrow keys.
We were changing the user's user_option.bookmark_auto_delete_preference
to whatever they changed it to in the bookmark modal to use as default
for future bookmarks. However this was leading to a lot of confusion
since if you wanted to set it for one bookmark you had to remember to
change it back on the next one.
This commit removes that automatic functionality, and instead moves
the bookmark auto delete preference to User Preferences > Interface
in an explicit dropdown.
This commit adds a new notification that gets sent to admins when the site gets new features after an upgrade/deploy. Clicking on the notification takes the admin to the admin dashboard at `/admin` where they can see the new features under the "New Features" section.
