Fixes race condition happening when multiple plugins that add extensible
area elements are loaded by the client. The issue is caused by the state
update of the extensible area items set by plugins, based on previous
state without using a callback. Replaced direct state updates with the
appropriate callback pattern to ensure consistent state changes.
* Fix: allow CORS requests to graphql API
In cluster setups the Graphql API endpoints are fetched as a CORS
request. We need to allow that.
* Fix: Allow CORS requests to ping endpoint
In cluster setups the ping is sent directly to the BBB server. So it
needs to allow CORS requests for cluster setups.
* Fix: construct relative API path for cluster setups
* Fix: adjust docs for cluster setup
As bbb-html5 client is static, setup instructions for cluster setup have
to be changed accordingly.
* Fix docs: remove superfluous ```yaml
This must have been introduced by accident.

Previously, we checked if a presentation existed before inserting it into the database. However, concurrent checks sometimes led to race conditions where the same presentation was inserted twice, causing errors and blocking subsequent page additions. This update removes the existence check and directly attempts to insert the presentation using an "IF NOT EXISTS" clause. This streamlines the process, enhances performance, and prevents ID duplication errors.
Ensure that the GraphQL reconnection—and thus the user's Hasura role update from `bbb_client_not_in_meeting` to `bbb_client`—occurs before the client is informed they've joined (`joined=true`). This prevents a race condition where the client might send GraphQL queries before having the necessary permissions, as only `bbb_client` can perform most queries. By updating the role first, we guarantee the client can successfully execute queries after joining.
GhostScript is incorrectly inferring the orientation of a slide by looking at the rotation of SVG elements such as whiteboard text. This PR forces GhostScript to retain the orientation of each page.

Commit 26815f4679 was seemingly lost
during a merge in the 3.0.x-release branch. Nothing breaks, but we're
missing the log info originally added via that commit.
Restore the changes in 26815f4679:
- Add secondsToActivateAudio, inputDeviceId, outputDeviceId and isListenOnly
to audio_joined.extraInfo
- Add inputDeviceId, outputDeviceId and isListenOnly to
audio_failure.extraInfo
- Add a try-catch to the device enforcement procedure triggered by
onAudioJoin - it may throw and block the modal.
We currently use full renegotiation for audio, video, and screen sharing
reconnections, which involves re-creating transports and signaling channels
from scratch. While effective in some scenarios, this approach is slow and,
especially with outbound cameras and screen sharing, prone to failures.
To counter that, WebRTC provides a mechanism to restart ICE without needing
to re-create the peer connection. This allows us to avoid full renegotiation
and bypass some server-side signaling limitations. Implementing ICE restart
should make outbound camera/screen sharing reconnections more reliable and
faster.
This commit implements the ICE restart procedure for all WebRTC components'
*outbound* peers. It is based on bbb-webrtc-sfu >= v2.15.0-beta.0, which
added support for ICE restart requests. This feature is *off by default*.
To enable it, adjust the following flags:
- `/etc/bigbluebutton/bbb-webrtc-sfu/production.yml`: `allowIceRestart: true`
- `/etc/bigbluebutton/bbb-html5.yml`: `public.kurento.restartIce`
* Refer to the inline documentation; this can be enabled on the client side
per media type.
* Note: The default max retries for audio is lower than for cameras/screen
sharing (1 vs 3). This is because the full renegotiation process for audio
is more reliable, so ICE restart is attempted first, followed by full
renegotiation if necessary. This approach is less suitable for cameras/
screen sharing, where longer retry periods for ICE restart make sense
since full renegotation there is... iffy.
Endpoints that are inbound/`recvonly` only (client's perspective) do *not*
support ICE restart yet. There are two main reasons:
- Server-side changes are required to support `recvonly` endpoints,
particularly the proper handling of the server’s `setup` role in the
its SDPs during an ICE restart. These changes are too broad for now,
so they are deferred to future releases (SFU@v2.16).
- Full reconnections for `recvonly` endpoints are currently reliable,
unlike for `send*` endpoints. ICE restarts could still provide benefits
for `recvonly` endpoints, but we need the server updates first.
- We were sending one websocket message for each removed shape, send only one with all IDs.
- The shape limit verification was not always working with rapid updates and if somehow the db got more shapes,
the users couldn't update or delete any shape anymore
- Unnecessary remove shape messages were being sent to the server when going over limit
