* Send error response when update metadata fails.
Keeping it simple for the first implementation.
- Send error response only if request_id != 0
- Two kinds of errors notified
o does not have permissions - NOT_ALLOWED
o attributes exceeds size limits - INVALID_ARGUMENT
* Check size limits on metadata and name set from client.
Added a name length limit also.
* check name length in service update participant path also
* limit check in limit config
* update protocol
* longer keys

o attributes exceeds size limits - INVALID_ARGUMENT
* Support for participant attributes
* move metadata setters to LocalParticipant
* address feedback
* forward error
* update go mod
* update attributes first
That is the main change. Changed variable name to `isExpectedToResume`
everywhere to be consistent.
Planning to use the callback value in relays to determine if the down
track should be closed or switched to a different up track.
* Handle UpdateLocalAudioTrack and UpdateLocalVideoTrack.
- Update the TrackInfo
- NOTE: populating Stereo and DisableDtx fields although there are
features now.
- The audio features in UpdateLocalAudioTrack is applied as is,
i. e. the update has the latest set of features.
- Emits a track update which will broadcast a participant update.
TODO:
-----
- Telemetry event with track update?
* update deps
It is possible that migration could trigger without migrating out node
knowing about it. So, when a migration started notification comes in,
set up migration timer if not already set.
* Support XR request/response for rtt calculation
* Update pkg/sfu/downtrack.go

* Do not synthesise DISCONNECT on session change.
v12 clients can handle session change based on identity.
* change for testf
* Squelch participant update if close reason is DUPLICATE_IDENTITY.
* fix test
* comment
* Clean up participant close reason a bit
* fix test
* test
* Use a participant worker queue in room.
Removes selectively needing to call things in goroutine from
participant.
Also, a bit of drive-by clean up.
* spelling
* prevent race
* don't need to remove in goroutine as it is already running in the worker
* worker will get cleaned up in state change callback
* create participant worker only if not created already
* ref count participant worker
* maintain participant list
* clean up oldState
* Augment LeaveRequest with alternate regions to connect.
* update protocol and issue resume action on close if expected to resume
* use current protocol in tests
* address feedback
* Add a simulation scenario to disconnect signal channel on resume
- Requesting that scenario add that participant to a map with a timeout
of 5 seconds.
- If a resume (reconnect = 1) happens before the timeout, the signalling
channel is closed immediately on resume.
- There is a clean up worker which will remove entries from the map when
they timout.
- The participant is also removed from the map if the disconnect on
resume is invoked once.
* simulate disconnect signal on resume no messages
* comment
* comment
* Close all retries
* update deps
* abort resume only if simulation applied
* Revert SIP change
PacketsLost may not provide useful if repairs are discounting the loss.
So, out-of-order packets are an indication of loss and maybe subsequent
repair. Note that out-of-order could be just out-of-order by a short
amount of time, but a lot of that happening is not good either.
So, out-of-order could provide a decent view of link quality.
* Consolidate TrackInfo.
TrackInfo was spread across a bit. Consolidating it.
* TODO comments
* test
* update TrackInfo on SSRC change
* further consolidation
* log mimes only
* update receivers on SSRC set
* clone proto on return
* feedback: break loop on mime match
* prevent data race
* 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
* Add option to issue full reconnect on data channel error.
There are situations where send data packet fails because of "stream
closed". It is unclear when that happens. Seems to be after an
ICERestart after ICE failed and connection type switching to TURN
from ICE.
Once the failure happens, it is not recoverable. Potentially, it is
recoverable, but unclear where the problem lies. Attempts to reproduce
looking at the pattern of failures has been unsuccesful.
In the mean time, adding an option to issue full reconnect
when send data packet fails.
* typo
* Add control of playout delay
Add config to enable playout delay. The delay will be limited by
[min,max] in the config option and calculated by upstream & downstream
RTT.
* check protocol version to enable playout delay
* Move config to room, limit playout-delay update interval, solve comments
* Remove adaptive playout-delay
* Remove unused config
