Besides, the method that you described will not solve the issue reported by the bug. There is no point that provides different API for C and PHP written save handlers, IMO. For PHP7 though, I definately want a redesign of the session APIs and > it's on my TODO list for when I have some spare time to work on it. > I think you have misunderstanding for session management. One example is that you don't understand nature of browser and server communication. It's _asynchronous_ by it's nature, yet you insisted _syncronous_ operation. Without this understanding, session cannot be managed correctly/precisely. Regards, -- Yasuo Ohgaki yohgaki@ohgaki.net
