BaseIOStream using non-blocking sockets. SSLIOStream: SSL-aware version of IOStream. PipeIOStream: Pipe-based IOStream implementation. Base class class tornado.iostream.BaseIOStream(max_buffer_size: int Any)[source] Pipe-based IOStream implementation. The constructor takes an integer file descriptor (such as one returned by os.pipe [https://docs.python.org/3.6/library/os.html#os.pipe]) rather than which fixes a problem in which the child could not detect that the parent process had closed its stdin pipe. Subprocess.set_exit_callback now works for subprocesses created without an explicit io_loop parameter
