The format for server endpoint descriptions is a simple byte string. It is a prefix naming the type of endpoint, then a colon, then the arguments for that endpoint. For example, you can call it like this to create an endpoint that will listen on TCP port 80:: serverFromString(reactor, "tcp:80") Additional arguments may be specified as keywords, separated with colons. For example, you can specify the interface for a TCP server endpoint to bind to like this:: serverFromString(reactor, "tcp:80:interface=127.0.0.1") SSL server endpoints may be specified with the 'ssl' prefix, and the private key and certificate files may be specified by the C{privateKey} and C{certKey} arguments:: serverFromString( reactor, "ssl:443:privateKey=key.pem:certKey=crt.pem") If a private key file name (C{privateKey}) isn't provided, a "server.pem" file is assumed to exist which contains the private key. If the certificate file name (C{certKey}) isn't provided, the private key file is assumed to contain the certificate as well. You may escape colons in arguments with a backslash, which you will need to use if you want to specify a full pathname argument on Windows:: serverFromString(reactor, "ssl:443:privateKey=C\:/key.pem:certKey=C\:/cert.pem") finally, the 'unix' prefix may be used to specify a filesystem UNIX socket, optionally with a 'mode' argument to specify the mode of the socket file created by C{listen}:: serverFromString(reactor, "unix:/var/run/finger") serverFromString(reactor, "unix:/var/run/finger:mode=660") This function is also extensible; new endpoint types may be registered as L{IStreamServerEndpointStringParser} plugins. See that interface for more information. @param reactor: The server endpoint will be constructed with this reactor. @param description: The strports description to parse. @type description: L{str} @return: A new endpoint which can be used to listen with the parameters given by C{description}. @rtype: L{IStreamServerEndpoint<twisted.internet.interfaces.IStreamServerEndpoint>} @raise ValueError: when the 'description' string cannot be parsed. @since: 10.2 i i N( Ru Rz R� R� Rw t _endpointServerFactories( R� R� t nameOrPluginR� Rj R� R� ( ( s] /opt/cpanel-ccs/.develop/virtualenv/lib/python2.7/site-packages/twisted/internet/endpoints.pyR: � s >c C` s= d \ } } x* | | f D] } | j | | | � } q W| S( s� Quote an argument to L{serverFromString} and L{clientFromString}. Since arguments are separated with colons and colons are escaped with backslashes, some care is necessary if, for example, you have a pathname, you may be tempted to interpolate into a string like this:: serverFromString(reactor, "ssl:443:privateKey=%s" % (myPathName,)) This may appear to work, but will have portability issues (Windows pathnames, for example). Usually you should just construct the appropriate endpoint type rather than interpolating strings, which in this case would be L{SSL4ServerEndpoint}. There are some use-cases where you may need to generate such a string, though; for example, a tool to manipulate a configuration file which has strports descriptions in it. To be correct in those cases, do this instead:: serverFromString(reactor, "ssl:443:privateKey=%s" % (quoteStringArgument(myPathName),)) @param argument: The part of the endpoint description string you want to pass through. @type argument: C{str} @return: The quoted argument. @rtype: C{str} s \:( t replace( t argumentR� R� t c( ( s] /opt/cpanel-ccs/.develop/virtualenv/lib/python2.7/site-packages/twisted/internet/endpoints.pyt quoteStringArgument� s c O` s t | � d k r7 t | d � | d <| d | d <nF t | � d k r} d | k rl t | d � | d <q} | d | d <n y t | d � | d <Wn t k r� n Xy t | d � | d <Wn t k r� n Xy | d d f | d <Wn t k r n X| S( s$ Perform any argument value coercion necessary for TCP client parameters.

Client description strings are much like server description strings, although they take all of their arguments as keywords, aside from host and port. You can create a TCP client endpoint with the 'host' and 'port' arguments, like so:: clientFromString(reactor, "tcp:host=www.example.com:port=80") or, without specifying host and port keywords:: clientFromString(reactor, "tcp:www.example.com:80") Or you can specify only one or the other, as in the following 2 examples:: clientFromString(reactor, "tcp:host=www.example.com:80") clientFromString(reactor, "tcp:www.example.com:port=80") or an SSL client endpoint with those arguments, plus the arguments used by the server SSL, for a client certificate:: clientFromString(reactor, "ssl:web.example.com:443:" "privateKey=foo.pem:certKey=foo.pem") to specify your certificate trust roots, you can identify a directory with PEM files in it with the C{caCertsDir} argument:: clientFromString(reactor, "ssl:host=web.example.com:port=443:" "caCertsDir=/etc/ssl/certs") Both TCP and SSL client endpoint description strings can include a 'bindAddress' keyword argument, whose value should be a local IPv4 address. This fixes the client socket to that IP address:: clientFromString(reactor, "tcp:www.example.com:80:" "bindAddress=192.0.2.100") NB: Fixed client ports are not currently supported in TCP or SSL client endpoints. The client socket will always use an ephemeral port assigned by the operating system You can create a UNIX client endpoint with the 'path' argument and optional 'lockfile' and 'timeout' arguments:: clientFromString( reactor, b"unix:path=/var/foo/bar:lockfile=1:timeout=9") or, with the path as a positional argument with or without optional arguments as in the following 2 examples:: clientFromString(reactor, "unix:/var/foo/bar") clientFromString(reactor, "unix:/var/foo/bar:lockfile=1:timeout=9") This function is also extensible; new endpoint types may be registered as L{IStreamClientEndpointStringParserWithReactor} plugins.
