There doesn't seem to be a way to catch a 403 Forbidden error opening a
websocket with JavaScript, so this commit changes the behaviour to this:
open the websocket normally, send one "kick" message, close the
websocket.
This should eliminate the possibilty of the websocket-closing background
task closing a newly opened websocket that hasn't yet ponged our ping
(if we have even sent a ping yet).
We now time the interval between consecutive tasks. This is more precise
than using the constant interval the task is supposed to run at since
there is some drift on each run (~0.004s).
Also adds "visibility: hidden;" to `disappear`. It would replace
"opacity: 0;" but Firefox acts weird with only visibility set, it only
half works until you switch between desktop and mobile view. IDK this
isn't that important.
This commit adds a unix socket on which you can receive internal events
as they happen. Currently the only supported event is a chat message
being added. Intended for external applications that depend on chat
messages, e.g. text-to-speech or Twitch Plays Pokémon.
As opposed to just the broadcaster token. This makes the broadcaster
username/password login mandatory, which previously was only mandatory
in the `auth_required` wrapper, but not elsewhere (so for example
leaving comments as the broadcaster was possible with the token only). A
less safe alternative to this would be to compare tokens in `check_auth`
once the Authorization header didn't match.
Also implements stack/queue behaviour where if the eyes limit would be
exceeded, either the new eyes cause the oldest eyes to be deleted OR
the new eyes aren't created at all. The default is the first option.
This commit adds the concept of eyes. One "eyes" is one instance of a
response to GET /stream.mp4. Currently the number of eyes clients can
have is unbounded, but this is a DoS vector.
Previously we only caught FileNotFoundError. If there was a
PermissionError for example, it would have percolated up and
stopped some background tasks.
When you press enter to submit a form and there are multiple submittable
inputs (e.g. type="image" / type="submit"), Firefox chooses the one that
appears first in markup. Before this commit the image input (aka the "I
want a new captcha" button) appeared before the submit button which
meant pressing enter just reloaded the captcha instead of submitting the
comment.
Ensures that if a client becomes idle the segment generator is exited
within a constant amount of time (probably more than this timeout
because of the ASGI server's write buffer and the OS's socket write
buffer, but still constant).
Client and server both close the connection if they don't hear from the
other party after a timeout period. This is a failsafe and should
improve reliability.
Might not be necessary, but if it is then it prevents a sitation where a
websocket is still open but we've forgotten about it, so we will never
broadcast any new messages to it and the client will be practically frozen in
time until they disconnect and open a new websocket.
Also update the user's last_seen when the websocket is closed. This prevents a
user with js enabled who's actually idle being considered absent and being
rotated when their websocket accidentally closes for a few seconds.
