864442 - "IndexError: tuple index out of range" from webidl compiler

Status: RESOLVED DUPLICATE of bug 843264

(Core :: DOM: Core & HTML, defect)

Description

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

Attachment: Problem patch. Not a fix.

The attached webidl now compiles fine (running with patch "863880.patch") when I comment out these two problem lines in RTCPeerConnection.webidl:

>  readonly attribute RTCIceConnectionState iceConnectionState;
>
>  // Next two lines cause IndexError: tuple index out of range
>//  sequence<MediaStream> getLocalStreams ();
>//  sequence<MediaStream> getRemoteStreams ();
>
>  MediaStream? getStreamById (DOMString streamId);

When I un-comment them (already done in the attached patch), I get this error:

Attachment: Full output

Decided to attach full output.

Note that it actually seems to say "YTHONDONTWRITEBYTECODE" on the failing line. Not sure what that's about. It says "PYTHONDONTWRITEBYTECODE" further up.

This looks like bug 843264, right?

I guess I should fix this now....  ;)
