1377225 - Calling getStats on closed RTCPeerConnection resolves to undefined

Status: RESOLVED DUPLICATE of bug 1056433

(Core :: WebRTC: Signaling, defect, P3)

Description

[mroberts]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36

Steps to reproduce:

The legacy callback-based getStats as well as the Promise-based getStats method return undefined instead of an RTCStatsReport when called on a closed RTCPeerConnection, as specified by http://w3c.github.io/webrtc-pc/#rtcpeerconnection-interface-extensions-2

To test this out, run the following code:

    (async () => {
      const pc = new RTCPeerConnection()
      pc.close()
      const report1 = await new Promise((resolve, reject) => pc.getStats(null, resolve, reject))
      const report2 = await pc.getStats(null)
      console.log(report1)
      console.log(report2)
    })()


Actual results:

I saw the following printed in the console:

    undefined
    undefined



Expected results:

I should see the following printed in the console:

    RTCStatsReport { size: 0 } 
    RTCStatsReport { size: 0 }
