I'm messing around with SSL.File in a threaded server, and have run into a strange difficulty. The object defaults to nonblocking mode, which is fine; but how do I set it to blocking mode? Here's my current code:
//sock is a straight Stdio.File initially
string handshake = sock->read(9, 1); if (sizeof(handshake) >= 2 && handshake[0] == 0x16 && handshake[1] == 0x03) { //Probable SSL handshake Pike.SmallBackend backend = Pike.SmallBackend(); sock->set_backend(backend); sock = SSLFile(sock, SSL.Context()); write("nonblocking_mode: %O\n", sock->is_nonblocking()); sock->accept(handshake); backend->call_out(sock->set_blocking, 0); while (sock->is_nonblocking()) backend(1.0); }
But this depends on being able to figure out when the socket has gone into blocking mode. To do that, I'm using my own subclass of SSL.File:
class SSLFile { inherit SSL.File; int is_nonblocking() {return nonblocking_mode;} }
to get around the fact that nonblocking_mode (the exact thing I'm looking for!) is flagged 'protected'. Why is this? And would an is_nonblocking method be a reasonable addition?
