This looks fine, but we need fishd to review.

Typically, in WebKit, we leave off the default case and let the compile tell us if we've forgotten an enum value (assuming the Chromium compile flags are set that way).

Just verified and Chromium is setup the same way. Removed default:.

Added default: back since it seems that the cr-linux buildbot isn't configured to use clang yet.

"Ice" -> ICE

see style guide

nit: inner enums should not be "Web" prefixed

> Source/WebKit/chromium/public/platform/WebIceOptions.h:50
> +        NO_RELAY,

nit: use WebKit CamelCase style naming.

nit: for webkit API, name enums like so:

  enum Foo {
      FooBar,
      FooBaz
  };

I'm lacking ICE familiarity, but I find the name of the enum very confusing.
What does UseCandidatesOption mean?

> Source/WebKit/chromium/public/platform/WebIceOptions.h:68
> +    WebUseCandidatesOption useCandidates() const;

need to export this one?

nit: i'm confused by the name of this function.  "useCandidates" sounds like a command, yet
this is a const method that returns an enum value.  confusing.  is there a better name?

> Source/WebKit/chromium/public/platform/WebMediaHints.h:62
> +    bool audio() const;

nit: export methods?

See bug 81339 for answer.

Fixed.

I just used the JS specification naming here which indeed is quite confusing: use_candidates: "all", "no_relay", "only_relay". It means which kinds of candidates you want to use: only local, only relay or both. In the latest patch I rewrote it to:


    enum CandidateType {
        CandidateTypeAll,
        CandidateTypeNoRelay,
        CandidateTypeOnlyRelay,
    };

    WEBKIT_EXPORT CandidateType candidateTypeToUse() const;

Which hopefully is much clearer.

See above.

Fixed.

WebIceOptions is now renamed to WebICEOptions, will rename IceOptions in an follow-up patch.
