getaddrinfo(host, port, family=0, socktype=1, proto=0, allow_cname=True)Resolve host and port into addrinfo struct. Does the same thing as socket.getaddrinfo, but using `pyxmpp.resolver`. This makes it possible to reuse data (A records from the additional section of DNS reply) returned with SRV records lookup done using this module. :Parameters: - `host`: service domain name. - `port`: service port number or name. - `family`: address family. - `socktype`: socket type. - `proto`: protocol number or name. - `allow_cname`: when False CNAME responses are not allowed. :Types: - `host`: `unicode` or `str` - `port`: `int` or `str` - `family`: `int` - `socktype`: `int` - `proto`: `int` or `str` - `allow_cname`: `bool` :return: list of (family, socktype, proto, canonname, sockaddr). :returntype: `list` of (`int`, `int`, `int`, `str`, (`str`, `int`)) |
reorder_srv(records)Reorder SRV records using their priorities and weights. :Parameters: - `records`: SRV records to shuffle. :Types: - `records`: `list` of `dns.rdtypes.IN.SRV` :return: reordered records. :returntype: `list` of `dns.rdtypes.IN.SRV` |
resolve_srv(domain, service, proto='tcp')Resolve service domain to server name and port number using SRV records. A built-in service alias table will be used to lookup also some obsolete record names. :Parameters: - `domain`: domain name. - `service`: service name. - `proto`: protocol name. :Types: - `domain`: `unicode` or `str` - `service`: `unicode` or `str` - `proto`: `str` :return: host names and port numbers for the service or None. :returntype: `list` of (`str`,`int`) |
shuffle_srv(records)Randomly reorder SRV records using their weights. :Parameters: - `records`: SRV records to shuffle. :Types: - `records`: sequence of `dns.rdtypes.IN.SRV` :return: reordered records. :returntype: `list` of `dns.rdtypes.IN.SRV` |
