Yury Selivanov <yseliva...@gmail.com> added the comment: Let's quickly iterate over what's possible first:
* It's possible to check the type of the FD using "getsockopt(SOL_SOCKET, SO_TYPE)" on all platforms. * It's possible to check family/proto of the FD using "getsockopt(SOL_SOCKET, SO_DOMAIN/SO_PROTOCOL)" on Linux. Given the above I propose the following: 1. Passing a wrong type can be considered as a serious error. SOCK_STREAM is fundamentally different from SOCK_DGRAM. Because we have a way to validate socket type on all platforms, I propose to do this validation when we create a socket from an FD, and raise an error if the passed socket type isn't correct. 2. When Python is running with '-X dev' (new dev mode added by Victor), I propose to also validate socket.family and socket.proto on Linux, and raise a RuntimeWarning when they don't match. ---------- nosy: +pitrou, vstinner, yselivanov _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28134> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
