There's a race condition that may cause a client crash whenever a
connectionstatechange callback is cleaned up in a peer without a
valid peer connection present in our custom RTCPeerConnection wrapper.
Check for peerConnection availability in the WebRtcPeer wrapper before
trying to clean up its connectionstatechange callback.
There's a race condition that may cause a client crash whenever a
video-provider's unmount procedure is run, but its signalling websocket
is undefined. The WS's callback handlers are re-assigned without
checking for the socket's availability, causing an unhandled TypeError.
The WS may be undefined in a couple of scenarios, e.g.: unmouting before
the socket was successfully set up, unmounting while a reconnect is in
place etc.
Check whether the socket exists before accessing it in video-provider's
componentWillUnmount routine.
A client crash may happen if either the Meeting collection or the
document's metadataProp attribute are undefined whenever the
getFromMeetingSettings util is called to fetch metadata.
It's debatable whether anything is working in the client if the
documents being accessed here are unavailable, but it'll still be logged
and might bork an ongoing reconnect.
Use optional chaining + nullish coalescing to avoid causing TypeErrors
in those situations while also returning default metadata values
properly.
When a sendrecv peer acts as the answerer, gUM is only called _after_
the remote offer is received. This is fine, but the error handling runs
different in that scenario in a way that eventual gUM errors are treated
as negotiation errors, leading to inconsistencies when surfacing the
error to end users.
If a peer is acting as answerer and is a transceiver, acquire the local
streams _before_ actual negotiation so that gUM errors are surfaced
correctly (and we spare uneeded negotiation steps).
The client may crash whenever a emoji rain animation is triggered, but
the interactions button element cannot be located. This happens because
the button coordinates are fetched without checking whether the element
exists.
Get the coordinate fetching method to return null if the
interactionsButton element cannot be located, and ignore the emoji rain
action if that is the case. Whenever no valid coordinates are found, log
an warning so we can track this and figure out what's happening with the
button.
Fix a few typos in the getInteractionsButtonCoordinates method.
Audio exit toasts are fired in some redundant situations, e.g.: when the
error help screen is toast.
Change the logic a bit so that it's only fired when the audio help modal
won't be shown, i.e.: when audio had succesfully connected.
There are some scenarios (e.g. WKWebView) where Bowser can't detect the
Safari version number correctly, which leads to a client crash due to an
invalid string.split call in UnsupportedComponent.
In such cases, use the WebKit version to determine it. If that's not the
case and the version number is still unavailable, log an warning and
return Infinity so that we do not deny access to the user (even if
we're uncertain about whether it's a supported browser);
* use label endMeetingForAll also for end button in settings dropdown
* change end button icon in settings dropdown from icon-bbb-application to icon-bbb-close
* fix(bbb-html5): customHeartbeat would not close stale sessions, +
The [disabled by default] custom heartbeat included in Meteor's server
does not end connections when they are considered unhealthy/stale, which
deviates a bit from the default implementation. See:
https://github.com/bigbluebutton/bigbluebutton/pull/11486.
This commit includes a call to the default heartbeat termination timeout
so sockets are correctly cleaned up when the custom heartbeat is
activated. It also adds a customHeartbeatUseDataFrames config to allow
controlling whether the custom heartbeat should use WS data frames as
valid heartbeats as well - this should only be useful for
testing/debugging purposes and the default behavior (true) is
maintained.
As a side note: this change spun off from an investigation where some
problematic networks were triggering periodic client re-connects due to
the default heartbeat failing. Investigation points to the control
frames being put alongside fragmented WS data frames and the server side
failing to recognize the former - which means pong frames would be missed and
the health check would fail. Since the default heartbeat _does not_
account for data frame traffic (eg DDP payloads), it would shut down the
client's WS even though it was healthy.
The custom heartbeat _does_ account for data frames, which mitigates
that scenario and prevents unecessary reconnections.
* fix(bbb-html5): frontend crash due to undefined vars in customHeartbeat
Meteor frontends may crash when customHeartbeat is enabled
due to an undefined access in the heartbeat`s logger.
Add optional chaining to the session props access so it won`t crash and tune down some log levels around that area.
