* Log cleanup pass
Demoted a bunch of logs to DEBUG, consolidated logs.
* use context logger and fix context var usage
* moved common error types, fixed tests
* Restrict scope of negotiation time out error logs
1. Log "negotiation failed" only if signal channel was active
within half window of negotiation timeout. Negotiation timeout currently
is at 15 seconds. Signal pings are every 10 seconds.
2. In transport.go, do not report negotiation timed out and do not
callback negotiation failure if the peer connection state is not
connected. Goal of negotiation failure tracker is to take remedial
action when an in-session negotiation fails. Seeing a bunch of cases
of the case hitting even without ICE connection forming. Negotiation
timer is not intended for those cases.
* fix test
* Add optional supervisor disable.
Used `DisableSupervisor` so that default can be enabled and
it can be disabled explicity. But, open to defaulting to disable
(i. e. change param to `EnableSupervisor`).
* Move nil check to call site
* Introduce `DISCONNECTED` connection quality.
Currently, this state happens when any up stream track does not
send any packets in an analysis window when it is expected to send
packets.
This can be used by participants to know the quality of a potentially
disconnected participant. Previously, it took 20 - 30 seconds for
the stale timeout to kick in and disconnect the limbo participant which
triggered a participant update through which other participants knew
about it.
Previously, `POOR` quality was also overloaded to denote that the
up stream is not sending any packets. With this change, that is a
separate indicator, i. e. `DISCONNECTED`.
* clean up
* Update deps
* spelling
* Participant traffic load.
Capturing information about participant traffic
- Upstream/Downstream
- Audio/Video/Data
- Packets/Bytes
This captures a notion of how much traffic load a participant is
generating.
Can be used to make allocation decisions.
* Clean up
* SIP patches
* reporter goroutine
* unlock
* move traffic stats from protocol
* check type
* Use a worker to report signal/data stats.
Was checking if reporting is needed on every update.
The check is wasted work if volume of signal/data messages is high
as reporting happens only once in 10 seconds.
Changing to a worker based on a timer. And also aligning with
telemetry reporting interval which defaults to 30 seconds.
* Remove unused constant
* Reduce logging
1. Do not print rtp stats if nil. Means that some subscribed tracks may
not have any logs (very short subscriptions which end before any
packet is sent).
2. Log ICE candidates only at the end, not when ICE connects. That logs
the selected ICE candidate pair.
3. Log ICE candidates only if not empty.
* Update some deps
