Bug 124369 – Modifying RTCIceCandidate object construction to match the spec

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Thiago de Barros Lacerda]

According to the spec the RTCIceCandidateInit parameter in RTCSessionDescription constructor is optional, which must not be nullable, and, if passed, must be a valid Dictionary.
If the keys are not present, the string object that stores them in the RTCIceCandidate class, must be null in those cases.
Also, if a key is present and its value is not valid an exception must be raised.

Nit: there isn't any reason to attempt the conversion to int if the key doesn't exist.

True story. Could you please also send me the xcode files patch?

Nit: in a follow-up patch (or the next time you are in this file) it would be good to use statics for this and the other string constants in this file to avoid allocating a String for each every time this is called.
