The default is 0. *serial*, an ``int``, the SOA serial number to use as the base for an IXFR diff sequence (only meaningful if *rdtype* is ``dns.rdatatype.IXFR``). *use_udp*, a ``bool``. If ``True``, use UDP (only meaningful for IXFR). *keyalgorithm*, a ``dns.name.Name`` or ``str``, the TSIG algorithm to use. Raises on errors, and so does the generator. Returns a generator of ``dns.message.Message`` objects. c@sNeZdZddZddZdejjfddZdd Z dd e dej j fd d Z dS)z$xfr..DummyTransactionManagercSs|||rtjjn|f|_dSr)r remptyinfo)rr[rrrrrr sz-xfr..DummyTransactionManager.__init__cS|jSr)rvrrrrorigin_information z7xfr..DummyTransactionManager.origin_informationrcSrArrBrxrrr get_classrSz.xfr..DummyTransactionManager.get_classcSrArrBrxrrrreaderrSz+xfr..DummyTransactionManager.readerF replacementcSsGddd}ttjj|S)Nc@seZdZddZddZdS)zExfr..DummyTransactionManager.writer..DummyTransactionc_sdSrr)rrPkwrrrnoprSzIxfr..DummyTransactionManager.writer..DummyTransaction.nopcSrwr)r)rr9rrr __getattr__rzzQxfr..DummyTransactionManager.writer..DummyTransaction.__getattr__N)rFrGrHrrrrrrDummyTransactions r)rr transaction Transaction)rr}rrrrwritersz+xfr..DummyTransactionManager.writerN)F)rFrGrHrryr rdataclass RdataClassr{r|boolrrrrrrrDummyTransactionManager s rT)createINSOAz. . %u 0 0 0 0rN) algorithmzcannot do a UDP AXFR)r rTransactionManagerrirr from_textr` RdataTypemaker make_queryra find_rrset authorityrrrrdataadduse_tsigrr%rr.rr/r-r0rn)rror_rprr6rrqrrr$r=rrYrsrtrrrrsetsoar<rr9r tm sock_typeryrrrrZs4E       "rZudp_modec  CsD|dur tj|\}} ntj|} t||||\} } }t|\} } |jdjtjj krv|t j krvt | t j|5}t|| | zt|||| || D]} qJWWddStjjyf|t jkrdYnwWdn1sqwYt | t j|}t|| | t|||| || D]} qWddS1swYdS)aConduct an inbound transfer and apply it via a transaction from the txn_manager. *where*, a ``str`` containing an IPv4 or IPv6 address, where to send the message. *txn_manager*, a ``dns.transaction.TransactionManager``, the txn_manager for this transfer (typically a ``dns.zone.Zone``). *query*, the query to send. If not supplied, a default query is constructed using information from the *txn_manager*. *port*, an ``int``, the port send the message to. The default is 53. *timeout*, a ``float``, the number of seconds to wait for each response message. If None, the default, wait forever. *lifetime*, a ``float``, the total number of seconds to spend doing the transfer. If ``None``, the default, then there is no limit on the time the transfer may take. *source*, a ``str`` containing an IPv4 or IPv6 address, specifying the source address. The default is the wildcard address. *source_port*, an ``int``, the port from which to send the message. The default is 0. *udp_mode*, a ``dns.query.UDPMode``, determines how UDP is used for IXFRs. The default is ``dns.UDPMode.NEVER``, i.e. only use TCP. Other possibilities are ``dns.UDPMode.TRY_FIRST``, which means "try UDP but fallback to TCP if needed", and ``dns.UDPMode.ONLY``, which means "try UDP and raise ``dns.xfr.UseTCP`` if it does not succeed. Raises on errors.
