The patches for these three bugs introduced a lot of build errors in code that's wrapped in "if ENABLE(PLUGIN_PROXY_FOR_VIDEO)":

        https://bugs.webkit.org/show_bug.cgi?id=36681
        https://bugs.webkit.org/show_bug.cgi?id=42770
        https://bugs.webkit.org/show_bug.cgi?id=45058

The attached patch fixes them.

I'm not 100% sure that changing "url = src()" to "url = currentSrc()" is correct, but I don't see anything else obvious to do here.

These methods do not belong on FrameLoader.  Just talk directly to the client.

What if frame is null?  Doesn't that crash?

Fixed Eric's suggestion, and fixed the "url = currentSrc()" line which didn't actually compile.  (Which kind of defeats the purpose)

Oops, didn't notice Adam's comment on the potential crash.  I might as well fix that too while I'm here.

Eric Carlson should really review this.

I don't know if we have guidelines about this, but my own policy is to only add a new copyright line when I make significant additions or changes to a file.

This is not correct, m_currentSrc may not have been set at this point (it is set a few lines later in this function). Use "getNonEmptyURLAttribute(srcAttr)" instead.

This flag is gone since 2014:

https://github.com/WebKit/WebKit/commit/898c9ce2877a71613aea3c172aaac20c3a5da95c & https://github.com/WebKit/WebKit/commit/3b7e09d5b985ce159418e6bac001ea9f62aa17fc

I don't think we have anything to fix here.

Marking this as 'RESOLVED CONFIGURATION CHANGED'.
