• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Tommy Widenflycht]

Navigator.getUserMedia is changed so that the audio and video members can either be a bool or a constraints object.

flag = ?  I guess the name ok is already taken...

You can merge these lines and delete the variable |request| if you like.

static_cast<bool>(m_audio)

WebKit uses C++ style casts.

Actually, is that even necessary?  Does the compiler complain if you leave off the explicit cast?

Tommy, would you be willing to fix these nits in a followup patch?  I see that you're already asleep and I want to save you the timezone round-trip.

Changed names to make more sense. "name" -> "mediaType" and "flag" -> "mediaRequested".

Here I am checking if the mediaType is a Dictionary or a boolean, and extracting the correct value.

Done.

I have not used c-style casts for ages and recently I started adding them, sigh. I'm sorry.

You are right, there is no need for a cast at all here.

Caused by a missing WEBKIT_EXPORT in WebMediaConstraints.h. Fixed.

Attachment 165746 [details] did not pass mac-ews (mac):
Output: http://queues.webkit.org/results/14032377

New failing tests:

Since the Mac build hasn't enabled MEDIA_STREAMS I am pretty sure my patch has nothing to do with this failure.

Yeah, running the tests on mac is new.  I think that's just a flaky test.
