How is incognito represented?

[Elliot Glaysher, 2016/03/10 21:00:35]

Right now, an incognito window is a different mojo user to make sure that we
don't reuse contexts between the main and OTR profiles. That might be the wrong
decision, and maybe there should be a
content::BrowserContext::InitializeChildProfile() to match c::B::Initialize().

(I'm not sure what you're asking.)

 interface ProfileService {
   // Returns the user profile directory.
-  GetDirectory(filesystem.Directory& dir);
+  GetDirectory(filesystem.Directory& dir) => (filesystem.FileError err);
 };
