You are incorrect. FTPClient.retrieveFile returns a Deferred that fires when the download is complete (or reports a failure). The API doc hints at this, but could be clearer. <http://twistedmatrix.com/documents/current/api/twisted.protocols.ftp.FTPClient.html#retrieveFile> > try: > ftpClient.retrieveFile('testFile.txt',test) > except: > print "Exception -", sys.exc_value > reactor.stop() > > > Can anyone shed a light? A direct correction to this snippet is: d = ftpClient.retrieveFile('testFile.txt', test) def eb(failure): print "Exception -", failure.getErrorMessage() reactor.stop() d.addErrback(eb) (Although like your code will only stop the reactor when an error occurs, and doesn't do anything when the download completes successfully.) -Andrew. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
