Proposed Patch

WebKit/chromium/public/WebFileSystem.h:61
 +      virtual void closeFile(FileHandle&) = 0;
so closeFile will reset the FileHandle to a special invalid value, but there does not appear to be any method here to initialize a FileHandle to hold the invalid value.  it would be nice if closeFile had some documentation describing this subtle behavior.

WebKit/chromium/public/WebFileSystem.h:49
 +      virtual bool fileExists(const WebString& path) = 0;
please provide default implementations for all of these methods.  that way you can implement ChromiumBridge methods in terms of these without having to land something on the Chromium side.  in general, any method implemented by the embedder should have a default implementation in the WebKit API.

WebKit/chromium/src/ChromiumBridge.cpp:328
 +      return webKitClient()->filePathToURL(path);
you can modify all of the existing file-related ChromiumBridge methods to first null-test fileSystem().  if that is null, then fallback to the old methods.
