2010-11-23  Bob Halley  <halley@dnspython.org>

	* (Version 1.9.2 released)

2010-11-23  Bob Halley  <halley@dnspython.org>

	* dns/dnssec.py (_need_pycrypto): DSA and RSA are modules, not
	  functions, and I didn't notice because the test suite masked
	  the bug!  *sigh*

2010-11-22  Bob Halley  <halley@dnspython.org>

	* (Version 1.9.1 released)

2010-11-22  Bob Halley  <halley@dnspython.org>

	* dns/dnssec.py: the "from" style import used to get DSA from
	  PyCrypto trashed a DSA constant.  Now a normal import is used
	  to avoid namespace contamination.

2010-11-20  Bob Halley  <halley@dnspython.org>

	* (Version 1.9.0 released)

2010-11-07  Bob Halley  <halley@dnspython.org>

	* dns/dnssec.py: Added validate() to do basic DNSSEC validation
	  (requires PyCrypto). Thanks to Brian Wellington for the patch.

	* dns/hash.py: Hash compatibility handling is now its own module.

2010-10-31  Bob Halley  <halley@dnspython.org>

	* dns/resolver.py (zone_for_name): A query name resulting in a
	  CNAME or DNAME response to a node which had an SOA was incorrectly
	  treated as a zone origin.  In these cases, we should just look
	  higher.  Thanks to Gert Berger for reporting this problem.

	* Added zonediff.py to examples.  This program compares two zones
	  and shows the differences either in diff-like plain text, or
	  HTML.  Thanks to Dennis Kaarsemaker for contributing this
	  useful program.

2010-10-27  Bob Halley  <halley@dnspython.org>

	* Incorporate a patch to use poll() instead of select() by
	  default on platforms which support it.  Thanks to
	  Peter Schüller and Spotify for the contribution.

2010-10-17  Bob Halley  <halley@dnspython.org>

	* Python prior to 2.5.2 doesn't compute the correct values for
	  HMAC-SHA384 and HMAC-SHA512.  We now detect attempts to use
	  them and raise NotImplemented if the Python version is too old.
	  Thanks to Kevin Chen for reporting the problem.

	* Various routines that took the string forms of rdata types and
	  classes did not permit the strings to be Unicode strings.
	  Thanks to Ryan Workman for reporting the issue.

	* dns/tsig.py: Added symbolic constants for the algorithm strings.
	  E.g. you can now say dns.tsig.HMAC_MD5 instead of
	  "HMAC-MD5.SIG-ALG.REG.INT".  Thanks to Cillian Sharkey for
	  suggesting this improvement.

	* dns/tsig.py (get_algorithm): fix hashlib compatibility; thanks to
	  Kevin Chen for the patch.

	* dns/dnssec.py: Added key_id() and make_ds().

	* dns/message.py: message.py needs to import dns.edns since it uses
	  it.

2010-05-04  Bob Halley  <halley@dnspython.org>

	* dns/rrset.py (RRset.__init__): "covers" was not passed to the
	  superclass __init__().  Thanks to Shanmuga Rajan for reporting
	  the problem.

2010-03-10  Bob Halley  <halley@dnspython.org>

	* The TSIG algorithm value was passed to use_tsig() incorrectly
	  in some cases.  Thanks to 'ducciovigolo' for reporting the problem.

2010-01-26  Bob Halley  <halley@dnspython.org>

	* (Version 1.8.0 released)

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.

2003-06-05  Bob Halley  <halley@dnspython.org>

        * (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.

2003-05-30  Bob Halley  <halley@dnspython.org>

        * (Version 1.0.0a1 released)
