1180879 - Joining the same room twice fails in odd ways

Status: RESOLVED DUPLICATE of bug 1194699

(Hello (Loop) :: Client, defect, P2)

Description

[Vladan Djeric (:vladan)]

Markus created a room and sent me the link (https://hello.firefox.com/5mE_gBV9ns0#myq38hIUo-jH3YgvrpJqfQ). I opened the link and started the conversation. 

Then I opened the link in a second tab (simultaneously) and clicked on Join Conversation. Hello said "Something went wrong" and showed a "Retry" button.

> eRoomView.shouldRenderRemoteVideo: unexpected roomState:  room-failed standaloneRoomViews.js:366:1
> OT.Publisher.onStreamAvailableError SourceUnavailableError: Unknown Error while getting user media sdk.js:3399:13
> OT.exception :: title: Unable to Publish (1500) msg: GetUserMedia sdk.js:3399:13
> 1500 Unknown Error while getting user media sdk.js:3399:13
> OT.exception :: title: Unable to Publish (1500) msg: Unknown Error while getting user media sdk.js:3399:13
> StandaloneRoomView.shouldRenderRemoteVideo: unexpected roomState:  room-failed

Then I closed the second tab and tried to open the link again in a new tab (total tabs=2) and clicked on "Join Conversation", this time the hello.firefox.com page didn't show any errors

Finally, Markus left the Hello room and I tried to open the URL in a second tab using the same link and the page told me there were already two people in the room (I think this is a known bug)

Vladan: Which platform are you on? This sounds a bit like Windows or Linux where you can't get access to the same device twice.

Could you try loading the http://mozilla.github.io/webrtc-landing/gum_test.html on two separate tabs and accessing at the same time?

I saw this on Windows 7 & Windows 8

Yes, that could be it

I tested on Windows 7:

- This page works in Aurora, Nightly single-process, and Nightly e10s
- In process-per-tab Nightly (dom.ipc.processCount=10, my own config) or when I open the link in 2 different Firefox profiles at the same time, I get "SourceUnavailableError: Failed to allocate videosource"

[:shell escalante]

shell find the bug we're fixing this issue with and associate - won't fix based on that if OK with team.

Marking as duplicate of bug 1194699 - my understanding per comment 2 that this is e10s related, and although that's a later bug, there's a bit clearer description and discussions ongoing there.
