Yes, it means we need to change opcache but could be way = easier than trying to hack the engine to support=20 > persistent Opcodes without ending with ... an opcache. OK. Agree. I just didn't understand how it was possible without any = change to the cache code. Personnally, if I implemented this, I would distribute a virtual file = tree through a stream wrapper. The stream wrapper would be the same for = all 'client' extensions. The fact to emulate a file tree would allow PHP = scripts to reference each other using a path similar to what we do in = packages : (dirname(__FILE__).'/relative/path'). We just need the stream = wrapper to emulate '.' and '..' and the whole range of relative paths is = available. This way, the script executes in an environment as familiar = as possible. To avoid conflicts, each extension would have a separate = root dir, something like ':///'. Off topic: I'd like to write a PHP7 RFC to extend the file system = features whose behavior remains different for plain files and for stream = wrappers. As most RFCs I write these days, this is an old subject but it = was refused for security reasons, as there was no way to distinguish a = 'remote' stream wrapper from a 'local' one. Now, the is_url flag allows = to restrict dangerous features, like include_path or globbing, to = 'local' wrappers, and some of these wrappers desperately need these = features (primarily phar developers and me, actually :). If you find it = crazy, please tell me before I write something more elaborate. Thanks. Fran=C3=A7ois
