s4-python: Move dnspython to lib/, like the other Python modules

This also avoids it from being installed if it's already present on the
system.

+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>
+
+        * Started test suites for zone.py and tokenizer.py.
+
+        * Added implementation of type KEY.
+
+        * DNS/rdata.py(_base64ify): \n could be emitted erroneously.
+
+        * DNS/rdtypes/ANY/SOA.py (SOA.from_text): The SOA RNAME field could
+        be set to the value of MNAME in common cases.
+
+        * DNS/rdtypes/ANY/X25.py: __init__ was broken.
+
+        * DNS/zone.py (from_text): $TTL handling erroneously caused the
+        next line to be eaten.
+
+        * DNS/tokenizer.py (Tokenizer.get): parsing was broken for empty
+        quoted strings.  Quoted strings didn't handle \ddd escapes.  Such
+        escapes are appear not to comply with RFC 1035, but BIND allows
+        them and they seem useful, so we allow them too.
+
+        * DNS/rdtypes/ANY/ISDN.py (ISDN.from_text): parsing was
+        broken for ISDN RRs without subaddresses.
+
+        * DNS/zone.py (from_file): from_file() didn't work because
+        some required parameters were not passed to from_text().
+
+2003-06-17  Bob Halley  <halley@dnspython.org>
+
+        * (Version 1.0.0b1 released)
+
+2003-06-17  Bob Halley  <halley@dnspython.org>
+
+        * Added implementation of type PX.
+
+2003-06-16  Bob Halley  <halley@dnspython.org>
+
+        * Added implementation of types CERT, GPOS, LOC, NSAP, NSAP-PTR.
+
+        * DNS/rdatatype.py (_by_value): A cut-and-paste error had broken
+        NSAP and NSAP-PTR.
+
+2003-06-12  Bob Halley  <halley@dnspython.org>
+
+        * Created a tests directory and started adding tests.
+
+        * Added "and its documentation" to the permission grant in the
+        license.
+
+2003-06-12  Bob Halley  <halley@dnspython.org>
+
+        * DNS/name.py (Name.is_wild): is_wild() erroneously raised IndexError
+        if the name was empty.
+
+2003-06-10  Bob Halley  <halley@dnspython.org>
+
+        * Added implementations of types AFSDB, X25, and ISDN.
+
+        * The documentation associated with the various rdata types has been
+        improved.  In particular, instance variables are now described.
+
+2003-06-09  Bob Halley  <halley@dnspython.org>
+
+        * Added implementations of types HINFO, RP, and RT.
+
+        * DNS/message.py (make_query): Document that make_query() sets
+        flags to DNS.flags.RD, and chooses a random query id.

+
+        * (Version 1.0.0a2 released)
+
+2003-06-05  Bob Halley  <halley@dnspython.org>
+
+        * DNS/node.py: removed __getitem__ and __setitem__, since
+        they are not used by the codebase and were not useful in
+        general either.
+
+        * DNS/message.py (from_file): from_file() now allows a
+        filename to be specified instead of a file object.
+
+        * DNS/rdataset.py: The is_compatible() method of the
+        DNS.rdataset.Rdataset class was deleted.
+
+2003-06-04  Bob Halley  <halley@dnspython.org>
+
+        * DNS/name.py (class Name): Names are now immutable.
+
+        * DNS/name.py: the is_comparable() method has been removed, since
+        names are always comparable.
+
+        * DNS/resolver.py (Resolver.query): A query could run for up
+        to the lifetime + the timeout.  This has been corrected and the
+        query will now only run up to the lifetime.
+
+2003-06-03  Bob Halley  <halley@dnspython.org>
+
+        * DNS/resolver.py: removed the 'new' function since it is not the
+        style of the library to have such a function.  Call
+        DNS.resolver.Resolver() to make a new resolver.
+
+2003-06-03  Bob Halley  <halley@dnspython.org>
+
+        * DNS/resolver.py (Resolver._config_win32_fromkey): The DhcpServer
+        list is space separated, not comma separated.
+
+2003-06-03  Bob Halley  <halley@dnspython.org>
+
+        * DNS/update.py: Added an update module to make generating updates
+        easier.
+
+2003-06-03  Bob Halley  <halley@dnspython.org>
+
+        * Commas were missing in some of the __all__ entries in various
+        __init__.py files.
