Status: RESOLVED FIXED

(Core :: WebRTC, defect, P2)

Description

[Rajmohan Banavi]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36

Steps to reproduce:

The current WebRTC spec mentions about RTCPeerConnectionState read only attribute in the peer connection object.


Actual results:

Did not locate this attribute in the pc object


Expected results:

Need to add support for the same.

[Eric Shepherd [:sheppy]]

The RTCPeerConnectionState enum has been documented: https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection#RTCPeerConnectionState_enum

RTCPeerConnection.connectionState has also been documented: https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/connectionState

The compatibility table on connectionState indicates the lack of implementation.

Leaving this in doc-needed state, however, because additions will have to be made to Firefox X for developers once it's implemented.

There has been no update to this bug in a few months.
Can this be prioritized please?
Thanks!

Moving to p3 because no activity for at least 1 year(s).

Chrome just landed connectionState in Chrome 72.

Comment 9

[Nils Ohlmeier [:drno]]

Since the PeerConnectionState appears to be an aggregate of ICE connection state and DTLS connection state I'm not sure if it makes sense to try to implement this without implementing the DTLS connection object as well.

Comment 10

[Byron Campen [:bwc]]

This is already causing timeouts in at least some web-platform-tests from upstream.

Comment 11

Hello!
Coming back to this in 2021, I wonder if there is a particular reason why this API is sitting at P2 (for years!) and not getting implemented?

Related:

• WebRTC 1.0 is moved from Candidate Recommentation to Recommentation
• Standard RTCPeerConnection Interface Definition from the W3C Draft

I was also iterating through some links over MDN docs & GitHub side, someone suggested using RTCPeerConnection.iceConnectionState as a workaround but according to the standard (and also MDN covers this very well), that wouldn't cover the exact same connection state information & behavior.

So, I wanted to bump this thread up to get more information.
Hopefully, this ticket would be triaged to higher priority so that an implementation might get into the next FF release cycle :)

Attachment: Bug 1265827 - Add connectionState to RTCPeerConnection. r=jib

Subscribes to dtls changes and aggragates them together with the iceConnectionState.
The aggregates state is exposed as RTCPeerConnection.connectionState.
The respective events are dispatched for connectionstatechange

Sorry for taking so long with this. Will try to get to review tomorrow.

[BugBot [:suhaib / :marco/ :calixte]]

The bug assignee didn't login in Bugzilla in the last months and this bug has priority 'P2'.
:mjf, could you have a look please?

:jib - have you had a chance to look at the patch?

Comment 16

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

Byron reviewed this on March 30th and unfortunately we haven't heard back from the contributor. Unfortunately, a lot of refactoring has happened in the code this patch touches since it was written. I'm thankful for the contributor providing this patch, and it's on us that we didn't review it in time.

At this point our best path forward may be for someone to commandeer the revision (keeping original attribution) and salvage necessary parts to where they need to go in the new structure. Byron would probably be able to do this quickest, since he did the refactor, with me coming in second.

Byron, does that sound right?

Comment 17

[Byron Campen [:bwc]]

I think that's the best way forward at this point.

Comment 18

[Alan Mantoux]

Any chances to see this land in a release?
Some apps would like to support Firefox for WebRTC

Comment 19

[Byron Campen [:bwc]]

Ok, I think we ought to be able to just implement this in terms of RTCDtlsTransport.state, which we already have implemented. I think this ought to be relatively easy.

Also, update meta files for tests that still fail for another reason.

Comment 23

[Byron Campen [:bwc]]

https://bugzilla.mozilla.org/show_bug.cgi?id=1643050#c2 indicates that split.https.html might work once this is implemented, but I have not noticed that. Just adding a note here.

Comment 24

[Byron Campen [:bwc]]

Looks like split.https.html works with this change now.

The severity field for this bug is set to S3. However, the following bug duplicate has higher severity:

• Bug 1635922: S2

:bwc, could you consider increasing the severity of this bug to S2?

Is this something we should call out in the Fx113 relnotes? Please nominate if so.

FYI MDN docs for this, including the MDN release note can be tracked in https://github.com/mdn/content/issues/26146. Note this is still waiting on browser compatibility data to be reviewed.
