Hello, I am investigating possibility of running FastCGI scripts with Lisp. This is doable at least on SBCL and (recently, on trunk atm) Clozure CL, since these implementations allow for creating a socket from file descriptor as integer -- and FastCGI protocol includes the script receiving a listening socket on FD 0 (stdin), which is a pattern sometimes seen in UNIX world (e.g. inetd). To get a socket from FD, I have to resort to using unexported functions in conjunction with platform-specific calls: (usocket::make-stream-server-socket #+ccl (ccl:make-socket :address-family :internet :type :stream :connect :passive :fd 0) #+sbcl (make-instance 'sb-bsd-sockets:inet-socket :descriptor 0)) Is it possible to incorporate this usage pattern into usocket, and if yes, how should I approach preparing the patch? I was thinking along the lines of exporting MAKE-STREAM-SOCKET, MAKE-STREAM-SERVER-SOCKET, and MAKE-DATAGRAM-SOCKET functions, making them accept either an implementation-specific socket or integer file descriptor as first argument, and adding relevant backend function for creating socket by FD and element type. Would this be a correct approach, or would you suggest another API? Thanks, Maciej. -- Maciej Pasternacki -><- http://www.pasternacki.net/ -><- http://www.3ofcoins.net/
