cef/cef1/tests/cefclient/extension_test.cpp
Marshall Greenblatt 801ff3ca43 - Update to Chromium revision 138235.
- Move to the new DOM storage backend. Persistent localStorage support will need to be re-implemented (issue ).
- Add CefV8Value::CreateUInt method and indicate that integer types are 32bit via usage of int32 and uint32 types (issue ).
- Add CefV8Context::Eval method for synchronous JavaScript execution that returns a value or exception (issue ).
- Move exception handling from an ExecuteFunction argument to a CefV8Value attribute (issue ).
- Make user data an attribute for all CefV8Value object types and not just CreateObject (issue ).
- Un-fork SQLitePersistentCookieStore by adding stub implementations for sqlite_diagnostics and browser_thread.
- Update tools/cef_parser.py to match the CEF3 version.
