s4-python: import a copy of the python dns library
This library is not installed on enough systems for us to rely on it being available. We use the system copy if possible, and fallback to this local copy Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>

+2010-01-13 Bob Halley <halley@dnspython.org>
+
+ * dns/dnssec.py: Added RSASHA256 and RSASHA512 codepoints; added
+ other missing codepoints to _algorithm_by_text.
+
+2010-01-12 Bob Halley <halley@dnspython.org>
+
+ * Escapes in masterfiles now work correctly. Previously they were
+ only working correctly when the text involved was part of a domain
+ name.
+
+ * dns/tokenizer.py: The tokenizer's get() method now returns Token
+ objects, not (type, text) tuples.
+
+2009-11-13 Bob Halley <halley@dnspython.org>
+
+ * Support has been added for hmac-sha1, hmac-sha224, hmac-sha256,
+ hmac-sha384 and hmac-sha512. Thanks to Kevin Chen for a
+ thoughtful, high quality patch.
+
+ * dns/update.py (Update::present): A zero TTL was not added if
+ present() was called with a single rdata, causing _add() to be
+ unhappy. Thanks to Eugene Kim for reporting the problem and
+ submitting a patch.
+
+ * dns/entropy.py: Use os.urandom() if present. Don't seed until
+ someone wants randomness.
+
+2009-09-16 Bob Halley <halley@dnspython.org>
+
+ * dns/entropy.py: The entropy module needs locking in order to be
+ used safely in a multithreaded environment. Thanks to Beda Kosata
+ for reporting the problem.
+
+2009-07-27 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (xfr): The socket was not set to nonblocking mode.
+ Thanks to Erik Romijn for reporting this problem.
+
+2009-07-23 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/SRV.py (SRV._cmp): SRV records were compared
+ incorrectly due to a cut-and-paste error. Thanks to Tommie
+ Gannert for reporting this bug.
+
+ * dns/e164.py (query): The resolver parameter was not used.
+ Thanks to Matías Bellone for reporting this bug.
+
+2009-06-23 Bob Halley <halley@dnspython.org>
+
+ * dns/entropy.py (EntropyPool.__init__): open /dev/random unbuffered;
+ there's no need to consume more randomness than we need. Thanks
+ to Brian Wellington for the patch.
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.7.1 released)
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * DLV.py was omitted from the kit
+
+ * Negative prerequisites were not handled correctly in _get_section().
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.7.0 released)
+
+2009-06-19 Bob Halley <halley@dnspython.org>
+
+ * On Windows, the resolver set the domain incorrectly. Thanks
+ to Brandon Carpenter for reporting this bug.
+
+ * Added a to_digestable() method to rdata classes; it returns the
+ digestable form (i.e. DNSSEC canonical form) of the rdata. For
+ most rdata types this is the same uncompressed wire form. For
+ certain older DNS RR types, however, domain names in the rdata
+ are downcased.
+
+ * Added support for the HIP RR type.
+
+2009-06-18 Bob Halley <halley@dnspython.org>
+
+ * Added support for the DLV RR type.
+
+ * Added various DNSSEC related constants (e.g. algorithm identifiers,
+ flag values).
+
+ * dns/tsig.py: Added support for BADTRUNC result code.
+
+ * dns/query.py (udp): When checking that addresses are the same,
+ use the binary form of the address in the comparison. This
+ ensures that we don't treat addresses as different if they have
+ equivalent but differing textual representations. E.g. "1:00::1"
+ and "1::1" represent the same address but are not textually equal.
+ Thanks to Kim Davies for reporting this bug.
+
+ * The resolver's query() method now has an optional 'source' parameter,
+ allowing the source IP address to be specified. Thanks to
+ Alexander Lind for suggesting the change and sending a patch.
+
+ * Added NSEC3 and NSEC3PARAM support.
+
+2009-06-17 Bob Halley <halley@dnspython.org>
+
+ * Fixed NSEC.to_text(), which was only printing the last window.
+ Thanks to Brian Wellington for finding the problem and fixing it.
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (xfr): Allow UDP IXFRs. Use "one_rr_per_rrset" mode when
+ doing IXFR.
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * Add "one_rr_per_rrset" mode switch to methods which parse
+ messages from wire format (e.g. dns.message.from_wire(),
+ dns.query.udp(), dns.query.tcp()). If set, each RR read is
+ placed in its own RRset (instead of being coalesced).
+
+2009-03-30 Bob Halley <halley@dnspython.org>
+
+ * Added EDNS option support.
+
+2008-10-16 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/DS.py: The from_text() parser for DS RRs did not
+ allow multiple Base64 chunks. Thanks to Rakesh Banka for
+ finding this bug and submitting a patch.
+
+2008-10-08 Bob Halley <halley@dnspython.org>
+
+ * Add entropy module.
+
+ * When validating TSIGs, we need to use the absolute name.
+
+2008-06-03 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (Message.set_rcode): The mask used preserved the
+ extended rcode, instead of everything else in ednsflags.
+
+ * dns/message.py (Message.use_edns): ednsflags was not kept
+ coherent with the specified edns version.
+
+2008-02-06 Bob Halley <halley@dnspython.org>
+
+ * dns/ipv6.py (inet_aton): We could raise an exception other than
+ dns.exception.SyntaxError in some cases.
+
+ * dns/tsig.py: Raise an exception when the peer has set a non-zero
+ TSIG error.
+
+2007-11-25 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.6.0 released)
+
+2007-11-25 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (_wait_for): if select() raises an exception due to
+ EINTR, we should just select() again.
+
+2007-06-13 Bob Halley <halley@dnspython.org>
+
+ * dns/inet.py: Added is_multicast().
+
+ * dns/query.py (udp): If the queried address is a multicast address, then
+ don't check that the address of the response is the same as the address
+ queried.
+
+2007-05-24 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/NAPTR.py: NAPTR comparisons didn't compare the
+ preference field due to a typo.
+
+2007-02-07 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py: Integrate code submitted by Paul Marks to
+ determine whether a Windows NIC is enabled. The way dnspython
+ used to do this does not work on Windows Vista.
+
+2006-12-10 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.5.0 released)
+
+2006-11-03 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/DHCID.py: Added support for the DHCID RR type.
+
+2006-11-02 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (udp): Messages from unexpected sources can now be
+ ignored by setting ignore_unexpected to True.
+
+2006-10-31 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (udp): When raising UnexpectedSource, add more
+ detail about what went wrong to the exception.
+
+2006-09-22 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (Message.use_edns): add reasonable defaults for
+ the ednsflags, payload, and request_payload parameters.
+
+ * dns/message.py (Message.want_dnssec): add a convenience method for
+ enabling/disabling the "DNSSEC desired" flag in requests.
+
+ * dns/message.py (make_query): add "use_edns" and "want_dnssec"
+ parameters.
+
+2006-08-17 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver.read_resolv_conf): If /etc/resolv.conf
+ doesn't exist, just use the default resolver configuration (i.e.
+ the same thing we would have used if resolv.conf had existed and
+ been empty).
+
+2006-07-26 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver._config_win32_fromkey): fix
+ cut-and-paste error where we passed the wrong variable to
+ self._config_win32_search(). Thanks to David Arnold for finding
+ the bug and submitting a patch.
+
+2006-07-20 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Answer): Add more support for the sequence
+ protocol, forwarding requests to the answer object's rrset.
+ E.g. "for a in answer" is equivalent to "for a in answer.rrset",
+ "answer[i]" is equivalent to "answer.rrset[i]", and
+ "answer[i:j]" is equivalent to "answer.rrset[i:j]".
+
+2006-07-19 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (xfr): Add IXFR support.
+
+2006-06-22 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/IN/IPSECKEY.py: Added support for the IPSECKEY RR type.
+
+2006-06-21 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/SPF.py: Added support for the SPF RR type.
+
+2006-06-02 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.4.0 released)
+
+2006-04-25 Bob Halley <halley@dnspython.org>
+
+ * dns/rrset.py (RRset.to_rdataset): Added a convenience method
+ to convert an rrset into an rdataset.
+
+2006-03-27 Bob Halley <halley@dnspython.org>
+
+ * Added dns.e164.query(). This function can be used to look for
+ NAPTR RRs for a specified number in several domains, e.g.:
+
+ dns.e164.query('16505551212',
+ ['e164.dnspython.org.', 'e164.arpa.'])
+
+2006-03-26 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver.query): The resolver deleted from
+ a list while iterating it, which makes the iterator unhappy.
+
+2006-03-17 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver.query): The resolver needlessly
+ delayed responses for successful queries.
+
+2006-01-18 Bob Halley <halley@dnspython.org>
+
+ * dns/rdata.py: added a validate() method to the rdata class. If
+ you change an rdata by assigning to its fields, it is a good
+ idea to call validate() when you are done making changes.
+ For example, if 'r' is an MX record and then you execute:
+
+ r.preference = 100000 # invalid, because > 65535
+ r.validate()
+
+ The validation will fail and an exception will be raised.
+
+2006-01-11 Bob Halley <halley@dnspython.org>
+
+ * dns/ttl.py: TTLs are now bounds checked to be within the closed
+ interval [0, 2^31 - 1].
+
+ * The BIND 8 TTL syntax is now accepted in the SOA refresh, retry,
+ expire, and minimum fields, and in the original_ttl field of
+ SIG and RRSIG records.
+
+2006-01-04 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py: The windows registry irritatingly changes the
+ list element delimiter in between ' ' and ',' (and vice-versa)
+ in various versions of windows. We now cope by always looking
+ for either one (' ' first).
+
+2005-12-27 Bob Halley <halley@dnspython.org>
+
+ * dns/e164.py: Added routines to convert between E.164 numbers and
+ their ENUM domain name equivalents.
+
+ * dns/reversename.py: Added routines to convert between IPv4 and
+ IPv6 addresses and their DNS reverse-map equivalents.
+
+2005-12-18 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/LOC.py (_tuple_to_float): The sign was lost when
+ converting a tuple into a float, which broke conversions of
+ south latitudes and west longitudes.
+
+2005-11-17 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: The 'origin' parameter to from_text() and from_file()
+ is now optional. If not specified, dnspython will use the
+ first $ORIGIN in the text as the zone's origin.
+
+ * dns/zone.py: Sanity checks of the zone's origin node can now
+ be disabled.
+
+2005-11-12 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py: Preliminary Unicode support has been added for
+ domain names. Running dns.name.from_text() on a Unicode string
+ will now encode each label using the IDN ACE encoding. The
+ to_unicode() method may be used to convert a dns.name.Name with
+ IDN ACE labels back into a Unicode string. This functionality
+ requires Python 2.3 or greater.
+
+2005-10-31 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.5 released)
+
+2005-10-12 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: Zone.iterate_rdatasets() and Zone.iterate_rdatas()
+ did not have a default rdtype of dns.rdatatype.ANY as their
+ docstrings said they did. They do now.
+
+2005-10-06 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py: Added the parent() method, which returns the
+ parent of a name.
+
+2005-10-01 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py: Added zone_for_name() helper, which returns
+ the name of the zone which contains the specified name.
+
+ * dns/resolver.py: Added get_default_resolver(), which returns
+ the default resolver, initializing it if necessary.
+
+2005-09-29 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver._compute_timeout): If time goes
+ backwards a little bit, ignore it.
+
+2005-07-31 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.4 released)
+
+2005-07-31 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (make_response): Trying to respond to a response
+ threw a NameError while trying to throw a FormErr since it used
+ the wrong name for the FormErr exception.
+
+ * dns/query.py (_connect): We needed to ignore EALREADY too.
+
+ * dns/query.py: Optional "source" and "source_port" parameters
+ have been added to udp(), tcp(), and xfr(). Thanks to Ralf
+ Weber for suggesting the change and providing a patch.
+
+2005-06-05 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py: The requirement that the "where" parameter be
+ an IPv4 or IPv6 address is now documented.
+
+2005-06-04 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py: The resolver now does exponential backoff
+ each time it runs through all of the nameservers.
+
+ * dns/resolver.py: rcodes which indicate a nameserver is likely
+ to be a "permanent failure" for a query cause the nameserver
+ to be removed from the mix for that query.
+
+2005-01-30 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.3 released)
+
+2004-10-25 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/TXT.py (TXT.from_text): The masterfile parser
+ incorrectly rejected TXT records where a value was not quoted.
+
+2004-10-11 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py: Added make_response(), which creates a skeletal
+ response for the specified query. Added opcode() and set_opcode()
+ convenience methods to the Message class. Added the request_payload
+ attribute to the Message class.
+
+2004-10-10 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py (from_xfr): dns.zone.from_xfr() in relativization
+ mode incorrectly set zone.origin to the empty name.
+
+2004-09-02 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py (Name.to_wire): The 'file' parameter to
+ Name.to_wire() is now optional; if omitted, the wire form will
+ be returned as the value of the function.
+
+2004-08-14 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (Message.find_rrset): find_rrset() now uses an
+ index, vastly improving the from_wire() performance of large
+ messages such as zone transfers.
+
+2004-08-07 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.2 released)
+
+2004-08-04 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py: sending queries to a nameserver via IPv6 now
+ works.
+
+ * dns/inet.py (af_for_address): Add af_for_address(), which looks
+ at a textual-form address and attempts to determine which address
+ family it is.
+
+ * dns/query.py: the default for the 'af' parameter of the udp(),
+ tcp(), and xfr() functions has been changed from AF_INET to None,
+ which causes dns.inet.af_for_address() to be used to determine the
+ address family. If dns.inet.af_for_address() can't figure it out,
+ we fall back to AF_INET and hope for the best.
+
+2004-07-31 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/NSEC.py (NSEC.from_text): The NSEC text format
+ does not allow specifying types by number, so we shouldn't either.
+
+ * dns/renderer.py: the renderer module didn't import random,
+ causing an exception to be raised if a query id wasn't provided
+ when a Renderer was created.
+
+ * dns/resolver.py (Resolver.query): the resolver wasn't catching
+ dns.exception.Timeout, so a timeout erroneously caused the whole
+ resolution to fail instead of just going on to the next server.
+
+2004-06-16 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/LOC.py (LOC.from_text): LOC milliseconds values
+ were converted incorrectly if the length of the milliseconds
+ string was less than 3.
+
+2004-06-06 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.1 released)
+
+2004-05-22 Bob Halley <halley@dnspython.org>
+
+ * dns/update.py (Update.delete): We erroneously specified a
+ "deleting" value of dns.rdatatype.NONE instead of
+ dns.rdataclass.NONE when the thing being deleted was either an
+ Rdataset instance or an Rdata instance.
+
+ * dns/rdtypes/ANY/SSHFP.py: Added support for the proposed SSHFP
+ RR type.
+
+2004-05-14 Bob Halley <halley@dnspython.org>
+
+ * dns/rdata.py (from_text): The masterfile reader did not
+ accept the unknown RR syntax when used with a known RR type.
+
+2004-05-08 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py (from_text): dns.name.from_text() did not raise
+ an exception if a backslash escape ended prematurely.
+
+2004-04-09 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py (_MasterReader._rr_line): The masterfile reader
+ erroneously treated lines starting with leading whitespace but
+ not having any RR definition as an error. It now treats
+ them like a blank line (which is not an error).
+
+2004-04-01 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.3.0 released)
+
+2004-03-19 Bob Halley <halley@dnspython.org>
+
+ * Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.
+
+2004-01-16 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py (_connect): Windows returns EWOULDBLOCK instead
+ of EINPROGRESS when trying to connect a nonblocking socket.
+
+2003-11-13 Bob Halley <halley@dnspython.org>
+
+ * dns/rdtypes/ANY/LOC.py (LOC.to_wire): We encoded and decoded LOC
+ incorrectly, since we were interpreting the values of altitiude,
+ size, hprec, and vprec in meters instead of centimeters.
+
+ * dns/rdtypes/IN/WKS.py (WKS.from_wire): The WKS protocol value is
+ encoded with just one octet, not two!
+
+2003-11-09 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Cache.maybe_clean): The cleaner deleted items
+ from the dictionary while iterating it, causing a RuntimeError
+ to be raised. Thanks to Mark R. Levinson for the bug report,
+ regression test, and fix.
+
+2003-11-07 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.2.0 released)
+
+2003-11-03 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py (_MasterReader.read): The saved_state now includes
+ the default TTL.
+
+2003-11-01 Bob Halley <halley@dnspython.org>
+
+ * dns/tokenizer.py (Tokenizer.get): The tokenizer didn't
+ handle escaped delimiters.
+
+2003-10-27 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver.read_resolv_conf): If no nameservers
+ are configured in /etc/resolv.conf, the default nameserver
+ list should be ['127.0.0.1'].
+
+2003-09-08 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver._config_win32_fromkey): We didn't
+ catch WindowsError, which can happen if a key is not defined
+ in the registry.
+
+2003-09-06 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.2.0b1 released)
+
+2003-09-05 Bob Halley <halley@dnspython.org>
+
+ * dns/query.py: Timeout support has been overhauled to provide
+ timeouts under Python 2.2 as well as 2.3, and to provide more
+ accurate expiration.
+
+2003-08-30 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: dns.exception.SyntaxError is raised for unknown
+ master file directives.
+
+2003-08-28 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: $INCLUDE processing is now enabled/disabled using
+ the allow_include parameter. The default is to process $INCLUDE
+ for from_file(), and to disallow $INCLUDE for from_text(). The
+ master reader now calls zone.check_origin_node() by default after
+ the zone has been read. find_rdataset() called get_node() instead
+ of find_node(), which result in an incorrect exception. The
+ relativization state of a zone is now remembered and applied
+ consistently when looking up names. from_xfr() now supports
+ relativization like the _MasterReader.
+
+2003-08-22 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: The _MasterReader now understands $INCLUDE.
+
+2003-08-12 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: The _MasterReader now specifies the file and line
+ number when a syntax error occurs. The BIND 8 TTL format is now
+ understood when loading a zone, though it will never be emitted.
+ The from_file() function didn't pass the zone_factory parameter
+ to from_text().
+
+2003-08-10 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.1.0 released)
+
+2003-08-07 Bob Halley <halley@dnspython.org>
+
+ * dns/update.py (Update._add): A typo meant that _add would
+ fail if the thing being added was an Rdata object (as
+ opposed to an Rdataset or the textual form of an Rdata).
+
+2003-08-05 Bob Halley <halley@dnspython.org>
+
+ * dns/set.py: the simple Set class has been moved to its
+ own module, and augmented to support more set operations.
+
+2003-08-04 Bob Halley <halley@dnspython.org>
+
+ * Node and all rdata types have been "slotted". This speeds
+ things up a little and reduces memory usage noticeably.
+
+2003-08-02 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.1.0c1 released)
+
+2003-08-02 Bob Halley <halley@dnspython.org>
+
+ * dns/rdataset.py: SimpleSets now support more set options.
+
+ * dns/message.py: Added the get_rrset() method. from_file() now
+ allows Unicode filenames and turns on universal newline support if
+ it opens the file itself.
+
+ * dns/node.py: Added the delete_rdataset() and replace_rdataset()
+ methods.
+
+ * dns/zone.py: Added the delete_node(), delete_rdataset(), and
+ replace_rdataset() methods. from_file() now allows Unicode
+ filenames and turns on universal newline support if it opens the
+ file itself. Added a to_file() method.
+
+2003-08-01 Bob Halley <halley@dnspython.org>
+
+ * dns/opcode.py: Opcode from/to text converters now understand
+ numeric opcodes. The to_text() method will return a numeric opcode
+ string if it doesn't know a text name for the opcode.
+
+ * dns/message.py: Added set_rcode(). Fixed code where ednsflags
+ wasn't treated as a long.
+
+ * dns/rcode.py: ednsflags wasn't treated as a long. Rcode from/to
+ text converters now understand numeric rcodes. The to_text()
+ method will return a numeric rcode string if it doesn't know
+ a text name for the rcode.
+
+ * examples/reverse.py: Added a new example program that builds a
+ reverse (address-to-name) mapping table from the name-to-address
+ mapping specified by A RRs in zone files.
+
+ * dns/node.py: Added get_rdataset() method.
+
+ * dns/zone.py: Added get_rdataset() and get_rrset() methods. Added
+ iterate_rdatas().
+
+2003-07-31 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: Added the iterate_rdatasets() method which returns
+ a generator which yields (name, rdataset) tuples for all the
+ rdatasets in the zone matching the specified rdatatype.
+
+2003-07-30 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.1.0b2 released)
+
+2003-07-30 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py: Added find_rrset() and find_rdataset() convenience
+ methods. They let you retrieve rdata with the specified name
+ and type in one call.
+
+ * dns/node.py: Nodes no longer have names; owner names are
+ associated with nodes in the Zone object's nodes dictionary.
+
+ * dns/zone.py: Zone objects now implement more of the standard
+ mapping interface. __iter__ has been changed to iterate the keys
+ rather than values to match the standard mapping interface's
+ behavior.
+
+2003-07-20 Bob Halley <halley@dnspython.org>
+
+ * dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses.
+
+2003-07-19 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.1.0b1 released)
+
+2003-07-18 Bob Halley <halley@dnspython.org>
+
+ * dns/tsig.py: The TSIG validation of TCP streams where not
+ every message is signed now works correctly.
+
+ * dns/zone.py: Zones can now be compared for equality and
+ inequality. If the other object in the comparison is also
+ a zone, then "the right thing" happens; i.e. the zones are
+ equal iff.: they have the same rdclass, origin, and nodes.
+
+2003-07-17 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py (Message.use_tsig): The method now allows for
+ greater control over the various fields in the generated signature
+ (e.g. fudge).
+ (_WireReader._get_section): UnknownTSIGKey is now raised if an
+ unknown key is encountered, or if a signed message has no keyring.
+
+2003-07-16 Bob Halley <halley@dnspython.org>
+
+ * dns/tokenizer.py (Tokenizer._get_char): get_char and unget_char
+ have been renamed to _get_char and _unget_char since they are not
+ useful to clients of the tokenizer.
+
+2003-07-15 Bob Halley <halley@dnspython.org>
+
+ * dns/zone.py (_MasterReader._rr_line): owner names were being
+ unconditionally relativized; it makes much more sense for them
+ to be relativized according to the relativization setting of
+ the reader.
+
+2003-07-12 Bob Halley <halley@dnspython.org>
+
+ * dns/resolver.py (Resolver.read_resolv_conf): The resolv.conf
+ parser did not allow blank / whitespace-only lines, nor did it
+ allow comments. Both are now supported.
+
+2003-07-11 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py (Name.to_digestable): to_digestable() now
+ requires an origin to be specified if the name is relative.
+ It will raise NeedAbsoluteNameOrOrigin if the name is
+ relative and there is either no origin or the origin is
+ itself relative.
+ (Name.split): returned the wrong answer if depth was 0 or depth
+ was the length of the name. split() now does bounds checking
+ on depth, and raises ValueError if depth < 0 or depth > the length
+ of the name.
+
+2003-07-10 Bob Halley <halley@dnspython.org>
+
+ * dns/ipv6.py (inet_ntoa): The routine now minimizes its output
+ strings. E.g. the IPv6 address
+ "0000:0000:0000:0000:0000:0000:0000:0001" is minimized to "::1".
+ We do not, however, make any effort to display embedded IPv4
+ addresses in the dot-quad notation.
+
+2003-07-09 Bob Halley <halley@dnspython.org>
+
+ * dns/inet.py: We now supply our own AF_INET and AF_INET6
+ constants since AF_INET6 may not always be available. If the
+ socket module has AF_INET6, we will use it. If not, we will
+ use our own value for the constant.
+
+ * dns/query.py: the functions now take an optional af argument
+ specifying the address family to use when creating the socket.
+
+ * dns/rdatatype.py (is_metatype): a typo caused the function
+ return true only for type OPT.
+
+ * dns/message.py: message section list elements are now RRsets
+ instead of Nodes. This API change makes processing messages
+ easier for many applications.
+
+2003-07-07 Bob Halley <halley@dnspython.org>
+
+ * dns/rrset.py: added. An RRset is a named rdataset.
+
+ * dns/rdataset.py (Rdataset.__eq__): rdatasets may now be compared
+ for equality and inequality with other objects. Rdataset instance
+ variables are now slotted.
+
+ * dns/message.py: The wire format and text format readers are now
+ classes. Variables related to reader state have been moved out
+ of the message class.
+
+2003-07-06 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py (from_text): '@' was not interpreted as the empty
+ name.
+
+ * dns/zone.py: the master file reader derelativized names in rdata
+ relative to the zone's origin, not relative to the current origin.
+ The reader now deals with relativization in two steps. The rdata
+ is read and derelativized using the current origin. The rdata's
+ relativity is then chosen using the zone origin and the relativize
+ boolean. Here's an example.
+
+ $ORIGIN foo.example.
+ $TTL 300
+ bar MX 0 blaz
+
+ If the zone origin is example., and relativization is on, then
+ This fragment will become:
+
+ bar.foo.example. 300 IN MX 0 blaz.foo.example.
+
+ after the first step (derelativization to current origin), and
+
+ bar.foo 300 IN MX 0 blaz.foo
+
+ after the second step (relativiation to zone origin).
+
+ * dns/namedict.py: added.
+
+ * dns/zone.py: The master file reader has been made into its
+ own class. Reader-related instance variables have been moved
+ form the zone class into the reader class.
+
+ * dns/zone.py: Add node_factory class attribute. An application
+ can now subclass Zone and Node and have a zone whose nodes are of
+ the subclassed Node type. The from_text(), from_file(), and
+ from_xfr() algorithms now take an optional zone_factory argument.
+ This allows the algorithms to be used to create zones whose class
+ is a subclass of Zone.
+
+
+2003-07-04 Bob Halley <halley@dnspython.org>
+
+ * dns/renderer.py: added new wire format rendering module and
+ converted message.py to use it. Applications which want
+ fine-grained control over the conversion to wire format may call
+ the renderer directy, instead of having it called on their behalf
+ by the message code.
+
+2003-07-02 Bob Halley <halley@dnspython.org>
+
+ * dns/name.py (_validate_labels): The NameTooLong test was
+ incorrect.
+
+ * dns/message.py (Message.to_wire): dns.exception.TooBig is
+ now raised if the wire encoding exceeds the specified
+ maximum size.
+
+2003-07-01 Bob Halley <halley@dnspython.org>
+
+ * dns/message.py: EDNS encoding was broken. from_text()
+ didn't parse rcodes, flags, or eflags correctly. Comparing
+ messages with other types of objects didn't work.
+
+2003-06-30 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.0.0 released)
+
+2003-06-30 Bob Halley <halley@dnspython.org>
+
+ * dns/rdata.py: Rdatas now implement rich comparisons instead of
+ __cmp__.
+
+ * dns/name.py: Names now implement rich comparisons instead of
+ __cmp__.
+
+ * dns/inet.py (inet_ntop): Always use our code, since the code
+ in the socket module doesn't support AF_INET6 conversions if
+ IPv6 sockets are not available on the system.
+
+ * dns/resolver.py (Answer.__init__): A dangling CNAME chain was
+ not raising NoAnswer.
+
+ * Added a simple resolver Cache class.
+
+ * Added an expiration attribute to answer instances.
+
+2003-06-24 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.0.0b3 released)
+
+2003-06-24 Bob Halley <halley@dnspython.org>
+
+ * Renamed module "DNS" to "dns" to avoid conflicting with
+ PyDNS.
+
+2003-06-23 Bob Halley <halley@dnspython.org>
+
+ * The from_text() relativization controls now work the same way as
+ the to_text() controls.
+
+ * DNS/rdata.py: The parsing of generic rdata was broken.
+
+2003-06-21 Bob Halley <halley@dnspython.org>
+
+ * (Version 1.0.0b2 released)
+
+2003-06-21 Bob Halley <halley@dnspython.org>
+
+ * The Python 2.2 socket.inet_aton() doesn't seem to like
+ '255.255.255.255'. We work around this.
+
+ * Fixed bugs in rdata to_wire() and from_wire() routines of a few
+ types. These bugs were discovered by running the tests/zone.py
+ Torture1 test.
+
+ * Added implementation of type APL.
+
+2003-06-20 Bob Halley <halley@dnspython.org>
+
+ * DNS/rdtypes/IN/AAAA.py: Use our own versions of inet_ntop and
+ inet_pton if the socket module doesn't provide them for us.
+
+ * The resolver now does a better job handling exceptions. In
+ particular, it no longer eats all exceptions; rather it handles
+ those exceptions it understands, and leaves the rest uncaught.
+
+ * Exceptions have been pulled into their own module. Almost all
+ exceptions raised by the code are now subclasses of
+ DNS.exception.DNSException. All form errors are subclasses of
+ DNS.exception.FormError (which is itself a subclass of
+ DNS.exception.DNSException).
+
+2003-06-19 Bob Halley <halley@dnspython.org>
+
+ * Added implementations of types DS, NXT, SIG, and WKS.
+
+ * __cmp__ for type A and AAAA could produce incorrect results.
+
+2003-06-18 Bob Halley <halley@dnspython.org>
+

+
+INTRODUCTION
+
+dnspython is a DNS toolkit for Python. It supports almost all record
+types. It can be used for queries, zone transfers, and dynamic
+updates. It supports TSIG authenticated messages and EDNS0.
+
+dnspython provides both high and low level access to DNS. The high
+level classes perform queries for data of a given name, type, and
+class, and return an answer set. The low level classes allow direct
+manipulation of DNS zones, messages, names, and records.
+
+To see a few of the ways dnspython can be used, look in the examples/
+directory.
+
+dnspython originated at Nominum where it was developed to facilitate
+the testing of DNS software. Nominum has generously allowed it to be
+open sourced under a BSD-style license, and helps support its future
+development by continuing to employ the author :).
+
+
+ABOUT THIS RELEASE
+
+This is dnspython 1.8.0
+
+New since 1.7.1:
+
+ Support for hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384
+ and hmac-sha512 has been contributed by Kevin Chen.
+
+ The tokenizer's tokens are now Token objects instead of (type,
+ value) tuples.
+
+Bugs fixed since 1.7.1:
+
+ Escapes in masterfiles now work correctly. Previously they
+ were only working correctly when the text involved was part of
+ a domain name.
+
+ When constructing a DDNS update, if the present() method was
+ used with a single rdata, a zero TTL was not added.
+
+ The entropy pool needed locking to be thread safe.
+
+ The entropy pool's reading of /dev/random could cause
+ dnspython to block.
+
+ The entropy pool did buffered reads, potentially consuming more
+ randomness than we needed.
+
+ The entropy pool did not seed with high quality randomness on
+ Windows.
+
+ SRV records were compared incorrectly.
+
+ In the e164 query function, the resolver parameter was not
+ used.
+
+New since 1.7.0:
+
+ Nothing
+
+Bugs fixed since 1.7.0:
+
+ The 1.7.0 kitting process inadventently omitted the code for the
+ DLV RR.
+
+ Negative DDNS prerequisites are now handled correctly.
+
+New since 1.6.0:
+
+ Rdatas now have a to_digestable() method, which returns the
+ DNSSEC canonical form of the rdata, suitable for use in
+ signature computations.
+
+ The NSEC3, NSEC3PARAM, DLV, and HIP RR types are now supported.
+
+ An entropy module has been added and is used to randomize query ids.
+
+ EDNS0 options are now supported.
+
+ UDP IXFR is now supported.
+
+ The wire format parser now has a 'one_rr_per_rrset' mode, which
+ suppresses the usual coalescing of all RRs of a given type into a
+ single RRset.
+
+ Various helpful DNSSEC-related constants are now defined.
+
+ The resolver's query() method now has an optional 'source' parameter,
+ allowing the source IP address to be specified.
+
+Bugs fixed since 1.6.0:
+
+ On Windows, the resolver set the domain incorrectly.
+
+ DS RR parsing only allowed one Base64 chunk.
+
+ TSIG validation didn't always use absolute names.
+
+ NSEC.to_text() only printed the last window.
+
+ We did not canonicalize IPv6 addresses before comparing them; we
+ would thus treat equivalent but different textual forms, e.g.
+ "1:00::1" and "1::1" as being non-equivalent.
+
+ If the peer set a TSIG error, we didn't raise an exception.
+
+ Some EDNS bugs in the message code have been fixed (see the ChangeLog
+ for details).
+
+New since 1.5.0:
+ Added dns.inet.is_multicast().
+
+Bugs fixed since 1.5.0:
+
+ If select() raises an exception due to EINTR, we should just
+ select() again.
+
+ If the queried address is a multicast address, then don't
+ check that the address of the response is the same as the
+ address queried.
+
+ NAPTR comparisons didn't compare the preference field due to a
+ typo.
+
+ Testing of whether a Windows NIC is enabled now works on Vista
+ thanks to code contributed by Paul Marks.
+
+New since 1.4.0:
+
+ Answer objects now support more of the python sequence
+ protocol, forwarding the requests to the answer rrset.
+ E.g. "for a in answer" is equivalent to "for a in
+ answer.rrset", "answer[i]" is equivalent to "answer.rrset[i]",
+ and "answer[i:j]" is equivalent to "answer.rrset[i:j]".
+
+ Making requests using EDNS, including indicating DNSSEC awareness,
+ is now easier. For example, you can now say:
+
+ q = dns.message.make_query('www.dnspython.org', 'MX',
+ want_dnssec=True)
+
+ dns.query.xfr() can now be used for IXFR.
+
+ Support has been added for the DHCID, IPSECKEY, and SPF RR types.
+
+ UDP messages from unexpected sources can now be ignored by
+ setting ignore_unexpected to True when calling dns.query.udp.
+
+Bugs fixed since 1.4.0:
+
+ If /etc/resolv.conf didn't exist, we raised an exception
+ instead of simply using the default resolver configuration.
+
+ In dns.resolver.Resolver._config_win32_fromkey(), we were
+ passing the wrong variable to self._config_win32_search().
+
+New since 1.3.5:
+
+ You can now convert E.164 numbers to/from their ENUM name
+ forms:
+
+ >>> import dns.e164
+ >>> n = dns.e164.from_e164("+1 555 1212")
+ >>> n
+ <DNS name 2.1.2.1.5.5.5.1.e164.arpa.>
+ >>> dns.e164.to_e164(n)
+ '+15551212'
+
+ You can now convert IPv4 and IPv6 address to/from their
+ corresponding DNS reverse map names:
+
+ >>> import dns.reversename
+ >>> n = dns.reversename.from_address("127.0.0.1")
+ >>> n
+ <DNS name 1.0.0.127.in-addr.arpa.>
+ >>> dns.reversename.to_address(n)
+ '127.0.0.1'
+
+ You can now convert between Unicode strings and their IDN ACE
+ form:
+
+ >>> n = dns.name.from_text(u'les-\u00e9l\u00e8ves.example.')
+ >>> n
+ <DNS name xn--les-lves-50ai.example.>
+ >>> n.to_unicode()
+ u'les-\xe9l\xe8ves.example.'
+
+ The origin parameter to dns.zone.from_text() and dns.zone.to_text()
+ is now optional. If not specified, the origin will be taken from
+ the first $ORIGIN statement in the master file.
+
+ Sanity checking of a zone can be disabled; this is useful when
+ working with files which are zone fragments.
+
+Bugs fixed since 1.3.5:
+
+ The correct delimiter was not used when retrieving the
+ list of nameservers from the registry in certain versions of
+ windows.
+
+ The floating-point version of latitude and longitude in LOC RRs
+ (float_latitude and float_longitude) had incorrect signs for
+ south latitudes and west longitudes.
+
+ BIND 8 TTL syntax is now accepted in all TTL-like places (i.e.
+ SOA fields refresh, retry, expire, and minimum; SIG/RRSIG
+ field original_ttl).
+
+ TTLs are now bounds checked when their text form is parsed,
+ and their values must be in the closed interval [0, 2^31 - 1].
+
+New since 1.3.4:
+
+ In the resolver, if time goes backward a little bit, ignore
+ it.
+
+ zone_for_name() has been added to the resolver module. It
+ returns the zone which is authoritative for the specified
+ name, which is handy for dynamic update. E.g.
+
+ import dns.resolver
+ print dns.resolver.zone_for_name('www.dnspython.org')
+
+ will output "dnspython.org." and
+
+ print dns.resolver.zone_for_name('a.b.c.d.e.f.example.')
+
+ will output ".".
+
+ The default resolver can be fetched with the
+ get_default_resolver() method.
+
+ You can now get the parent (immediate superdomain) of a name
+ by using the parent() method.
+
+ Zone.iterate_rdatasets() and Zone.iterate_rdatas() now have
+ a default rdtype of dns.rdatatype.ANY like the documentation
+ says.
+
+ A Dynamic DNS example, ddns.py, has been added.
+
+New since 1.3.3:
+
+ The source address and port may now be specified when calling
+ dns.query.{udp,tcp,xfr}.
+
+ The resolver now does exponential backoff each time it runs
+ through all of the nameservers.
+
+ Rcodes which indicate a nameserver is likely to be a
+ "permanent failure" for a query cause the nameserver to be removed
+ from the mix for that query.
+
+New since 1.3.2:
+
+ dns.message.Message.find_rrset() now uses an index, vastly
+ improving the from_wire() performance of large messages such
+ as zone transfers.
+
+ Added dns.message.make_response(), which creates a skeletal
+ response for the specified query.
+
+ Added opcode() and set_opcode() convenience methods to the
+ dns.message.Message class. Added the request_payload
+ attribute to the Message class.
+
+ The 'file' parameter of dns.name.Name.to_wire() is now
+ optional; if omitted, the wire form will be returned as the
+ value of the function.
+
+ dns.zone.from_xfr() in relativization mode incorrectly set
+ zone.origin to the empty name.
+
+ The masterfile parser incorrectly rejected TXT records where a
+ value was not quoted.
+
+New since 1.3.1:
+
+ The NSEC format doesn't allow specifying types by number, so
+ we shouldn't either. (Using the unknown type format is still
+ OK though.)
+
+ The resolver wasn't catching dns.exception.Timeout, so a timeout
+ erroneously caused the whole resolution to fail instead of just
+ going on to the next server.
+
+ The renderer module didn't import random, causing an exception
+ to be raised if a query id wasn't provided when a Renderer was
+ created.
+
+ The conversion of LOC milliseconds values from text to binary was
+ incorrect if the length of the milliseconds string was not 3.
+
+New since 1.3.0:
+
+ Added support for the SSHFP type.
+
+New since 1.2.0:
+
+ Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.
+
+This release fixes all known bugs.
+
+See the ChangeLog file for more detailed information on changes since
+the prior release.

+More examples
+
+It would be nice to have a tokenizer that used regular expressions
+because it would be faster.
+
+Teach the resolver about DNAME (right now it relies on the server adding

+
+Add TKEY support.
+
+TSIG works, but needs cleaning up -- probably better encapsulation of
+TSIG state to make things much simpler and easier to use.
