setup() Called before the handle() method to perform any initialization actions required. The default implementation does nothing.

handle() This function must do all the work required to service a request. The default implementation does nothing. Several instance attributes are available to it; the request is available as self.request; the client address as self.client_address; and the server instance as self.server, in case it needs access to per-server information. The type of self.request is different for datagram or stream services. For stream services, self.request is a socket object; for datagram services, self.re

finish() Called after the handle() method to perform any clean-up actions required. The default implementation does nothing. If setup() raises an exception, this function will not be called.

class socketserver.BaseRequestHandler This is the superclass of all request handler objects. It defines the interface, given below. A concrete request handler subclass must define a new handle() method, and can override any of the other methods. A new instance of the subclass is created for each request. setup() Called before the handle() method to perform any initialization actions required. The default implementation does nothing. handle() This function must do all the work requir

exception socket.timeout A subclass of OSError, this exception is raised when a timeout occurs on a socket which has had timeouts enabled via a prior call to settimeout() (or implicitly through setdefaulttimeout()). The accompanying value is a string whose value is currently always “timed out”. Changed in version 3.3: This class was made a subclass of OSError.

socket.SocketType This is a Python type object that represents the socket object type. It is the same as type(socket(...)).

socket.socketpair([family[, type[, proto]]]) Build a pair of connected socket objects using the given address family, socket type, and protocol number. Address family, socket type, and protocol number are as for the socket() function above. The default family is AF_UNIX if defined on the platform; otherwise, the default is AF_INET. The newly created sockets are non-inheritable. Changed in version 3.2: The returned socket objects now support the whole socket API, rather than a subset. Chan

socket.type The socket type.

socket.shutdown(how) Shut down one or both halves of the connection. If how is SHUT_RD, further receives are disallowed. If how is SHUT_WR, further sends are disallowed. If how is SHUT_RDWR, further sends and receives are disallowed.

socket.share(process_id) Duplicate a socket and prepare it for sharing with a target process. The target process must be provided with process_id. The resulting bytes object can then be passed to the target process using some form of interprocess communication and the socket can be recreated there using fromshare(). Once this method has been called, it is safe to close the socket since the operating system has already duplicated it for the target process. Availability: Windows. New in versi
