def doRead(self): if self.disconnected: # See the comment in the similar check in doWrite below. # Additionally, in order for anything other than returning # CONNECTION_DONE here to make sense, it will probably be necessary # to implement a way to switch back to TCP from TLS (actually, if # we did something other than return CONNECTION_DONE, that would be # a big part of implementing that feature). In other words, the # expectation is that doRead will be called when self.disconnected # is True only when the connection has been lost. It's possible # that the other end could stop speaking TLS and then send us some # non-TLS data. We'll end up ignoring that data and dropping the # connection. There's no unit tests for this check in the cases # where it makes a difference. The test suite only hits this # codepath when it would have otherwise hit the SSL.ZeroReturnError # exception handler below, which has exactly the same behavior as # this conditional. Maybe that's the only case that can ever be # triggered, I'm not sure. -exarkun return main.CONNECTION_DONE if self.writeBlockedOnRead: self.writeBlockedOnRead = 0 self._resetReadWrite() try: return Connection.doRead(self) except SSL.ZeroReturnError: return main.CONNECTION_DONE except SSL.WantReadError: return except SSL.WantWriteError: self.readBlockedOnWrite = 1 Connection.startWriting(self) Connection.stopReading(self) return except SSL.SysCallError, (retval, desc): if ((retval == -1 and desc == 'Unexpected EOF') or retval > 0): return main.CONNECTION_LOST log.err() return main.CONNECTION_LOST
