* Add a feature where a webcam broadcaster may manually invite others on
chat to watch, even if normally the other person would not be allowed.
For example, it will bypass the mutual webcam requirement setting and
allow the invited user to watch even if their own camera is not on.
* The button appears in Profile Modals and in the overflow menu on the
MessageBox component.
To help alleviate rocky chat server reboots, WhoList messages will be
withheld in the first 15 seconds from server start.
When a lot of chatters were online during a reboot (e.g. 50 or more),
they would all try and reconnect after 5 seconds and each login was
broadcasting Who List updates to everybody else logged in. With the
surge of logins in a short time, these WhoList messages would fill up
the buffers of each recipient, kicking them offline for being too slow
to keep up with messages; only for that recipient to reconnect again.
The average user may have experienced 2 or 3 disconnects when the chat
server reboots.
To help alleviate the spam of messages being sent out:
* Presence messages are withheld for the first 30 seconds ("has joined
the room" notifications)
* Now, WhoList messages are withheld for the first 15 seconds.
After 16 seconds of uptime, the server will send a WhoList to everybody
currently online to catch them up.
To accommodate this, the front-end will show a spinner and say "Waiting
for Who List..." when the page is connected but no WhoList has been
received yet. Under normal operation, this spinner won't be visible
beyond a brief moment as a WhoList is normally sent upon joining the
chat.
Add a feature where recent public channel messages can be echoed back to
newly joining users when they enter the chat room.
* Configure in settings.toml with EchoMessagesOnJoin. 0 = disable storage.
* Messages are stored in RAM and lost on a server reboot.
* A buffer of recent public messages per channel can be kept, e.g. for the
10 most recent messages.
* The settings can be reloaded with /reconfigure and the message buffers
will rebalance on the next message sent.
* When a new user logs in, a new "echo" message is sent that contains all
of the echoed messages on a "messages" list, in one WebSocket packet.
* Echoed messages are put above the ChatServer welcome messages.
* If a message is taken back, it's removed from the echo message buffer.
Other Changes
* Don't broadcast Presence messages within 30 seconds of the server boot, to
lessen a flood of messages when a lot of users were connected at reboot.
* Change the default "Join messages" setting on front-end to hide them in
public channels.
* For the admin buttons in ProfileModal, use the AlertModal instead of native
browser prompts.
* On the /nsfw command, BareRTC will issue an admin report to your main website
so you have visibility into when this command is used.
* On the server side, fix the "Open" command so it will prevent webcams from
connecting if the offerer had been Booted by the answerer, in addition to the
previous blocks about Mute and Block. Admin users can still connect always.
* Add a debug command `/watch username` to manually open somebody's camera on
chat. Note: the chat server enforces the permission to actually do so.
* Remove the /debug-dangerous-force-deadlock admin command.
