2018-07-18 Tomas Krizek <[email protected]>
* dns/hash.py: added deprecation warning. Module is no longer
necessary and will be removed in future versions.
2017-12-21 Daniel Robbins <[email protected]>
* dns/dnssec.py: migrated code from pycrypto (apparently no
longer maintained) to pycryptodome/pycryptodomex.
All tests passing.
2018-07-18 Tomas Krizek <[email protected]>
* Support for obsolete Python 2.6 and 3.3 (both EOL) dropped.
2017-01-02 Bob Halley <[email protected]>
* dns/e164.py: to_e164() was returning binary instead of text,
a Py2/Py3 merge bug.
* The IPv4 and IPv6 inet_ntoa() functions were returning binary
instead of text, a Py2/Py3 merge bug.
2017-01-01 Bob Halley <[email protected]>
* dns/rdatatype.py: CNAME is now a singleton, as the reasons
for permitting multiple CNAMEs are now largely historical.
2016-11-15 Bob Halley <[email protected]>
* Fixed regression where trailing zeros in APL RRs were not
suppressed, and then fixed the problem where trailing zeros
were not added back properly on python 3 when needed.
2016-10-10 Bob Halley <[email protected]>
* Added OPENPGPKEY RR support.
2016-09-30 Bob Halley <[email protected]>
* Much of the internals of dns.query.udp() and dns.query.tcp()
have been factored out into dns.query.send_udp(),
dns.query.receive_udp(), dns.query.send_tcp(), and
dns.query.receive_tcp(). Applications which want more control
over the socket may find the new routines helpful; for example
it would be easy to send multiple queries over a single TCP
connection.
2016-09-30 Bob Halley <[email protected]>
* (Version 1.15.0 released)
2016-09-29 Bob Halley <[email protected]>
* IDNA 2008 support is now available if the "idna" module has been
installed and IDNA 2008 is requested. The default IDNA behavior
is still IDNA 2003. The new IDNA codec mechanism is currently
only useful for direct calls to dns.name.from_text() or
dns.name.from_unicode(), but in future releases it will be
deployed throughout dnspython, e.g. so that you can read a
masterfile with an IDNA 2008 codec in force.
* By default, dns.name.to_unicode() is not strict about which
version of IDNA the input complies with. Strictness can be
requested by using one of the strict IDNA codecs.
* Add AVC RR support.
* Some problems with newlines in various output modes have been
addressed.
* dns.name.to_text() now returns text and not bytes on Python 3.x
* More miscellaneous fixes for the Python 2/3 codeline merge.
2016-05-27 Bob Halley <[email protected]>
* (Version 1.14.0 released)
* Add CSYNC RR support
* Fix bug in LOC which destroyed N/S and E/W distinctions within
a degree of the equator or prime merdian respectively.
* Misc. fixes to deal with fallout from the Python 2 & 3 merge.
[issue #156], [issue #157], [issue #158], [issue #159],
[issue #160].
* Running with python optimization on caused issues when
stripped docstrings were referenced. [issue #154]
* dns.zone.from_text() erroneously required the zone to be provided.
[issue #153]
2016-05-13 Bob Halley <[email protected]>
* dns/message.py (make_query): Setting any value which implies
EDNS will turn on EDNS if 'use_edns' has not been specified.
2016-05-12 Bob Halley <[email protected]>
* TSIG signature algorithm setting was broken by the Python 2
and Python 3 code line merge. Fixed.
2016-05-10 Bob Halley <[email protected]>
* (Version 1.13.0 released)
2016-05-10 Bob Halley <[email protected]>
* Dropped support for Python 2.4 and 2.5.
* Zone origin can be specified as a string.
* Support string representation for all DNSExceptions.
* Use setuptools not distutils
* A number of Unicode name bug fixes.
* Added support for CAA, CDS, CDNSKEY, EUI48, EUI64, and URI RR
types.
* Names now support the pickle protocol.
* NameDicts now keep the max-depth value correct, and update
properly.
* resolv.conf processing rejects lines with too few tokens.
* Ports can be specified per-nameserver in the stub resolver.
2016-05-03 Arthur Gautier
* Single source support for python 2.6+ and 3.3+
2014-09-04 Bob Halley <[email protected]>
* Comparing two rdata is now always done by comparing the binary
data of the DNSSEC digestable forms. This corrects a number of
errors where dnspython's rdata comparison order was not the
DNSSEC order.
* Add CAA implementation. Thanks to Brian Wellington for the
patch.
2014-09-01 Bob Halley <[email protected]>
* (Version 1.12.0 released)
2014-08-31 Bob Halley <[email protected]>
* The test system can now run the tests without requiring dnspython
to be installed.
2014-07-24 Bob Halley <[email protected]>
* The 64-bit version of Python on Windows has sys.maxint set to
2^31-1, yet passes 2^63-1 as the "unspecified bound" value in
slices. This is a bug in Python as the documentation says the
unspecified bound value should be sys.maxint. We now cope with
this. Thanks to Matthäus Wander for reporting the problem.
2014-06-21 Bob Halley <[email protected]>
* When reading from a masterfile, if the first content line
started with leading whitespace, we raised an ugly exception
instead of doing the right thing, namely using the zone origin as
the name. [#73] Thanks to Tassatux for reporting the issue.
* Added dns.zone.to_text() convenience method. Thanks to Brandon
Whaley <[email protected]> for the patch.
* The /etc/resolv.conf setting "options rotate" is now understood
by the resolver. If present, the resolver will shuffle the
nameserver list each time dns.resolver.query() is called. Thanks
to underrun for the patch. Note that you don't want to add
"options rotate" to your /etc/resolv.conf if your system's
resolver library does not understand it. In this case, just set
resolver.rotate = True by hand.
2014-06-19 Bob Halley <[email protected]>
* Escaping of Unicode has been corrected. Previously we escaped
and then converted to Unicode, but the right thing to do is
convert to Unicode, then escape. Also, characters > 0x7f should
NOT be escaped in Unicode mode. Thanks to Martin Basti for the
patch.
* dns.rdtypes.ANY.DNSKEY now has helpers functions to convert
between the numeric form of the flags and a set of human-friendly
strings. Thanks to Petr Spacek for the patch.
* RRSIGs did not respect relativization settings in to_text().
Thanks to Brian Smith for reporting the bug and submitting a
(slightly different) patch.
2014-06-18 Bob Halley <[email protected]>
* dns/rdtypes/IN/APL.py: The APL from_wire() method did not accept an
rdata length of 0 as valid. Thanks to salzmdan for reporting the
problem.
2014-05-31 Bob Halley <[email protected]>
* dns/ipv6.py: Add is_mapped()
* dns/reversename.py: Lookup IPv6 mapped IPv4 addresses in the v4
reverse namespace. Thanks to Devin Bayer. Yes, I finally fixed
this one :)
2014-04-11 Bob Halley <[email protected]>
* dns/zone.py: Do not put back an unescaped token. This was
causing escape processing for domain names to break. Thanks to
connormclaud for reporting the problem.
2014-04-04 Bob Halley <[email protected]>
* dns/message.py: Making a response didn't work correctly if the
query was signed with TSIG and we knew the key. Thanks to Jeffrey
Stiles for reporting the problem.
2013-12-11 Bob Halley <[email protected]>
* dns/query.py: Fix problems with the IXFR state machine which caused
long diffs to fail. Thanks to James Raftery for the fix and the
repeated prodding to get it applied :)
2013-09-02 Bob Halley <[email protected]>
* (Version 1.11.1 released)
2013-09-01 Bob Halley <[email protected]>
* dns/tsigkeyring.py (to_text): we want keyname.to_text(), not
dns.name.to_text(keyname). Thangs to wangwang for the fix.
2013-08-26 Bob Halley <[email protected]>
* dns/tsig.py (sign): multi-message TSIGs were broken for
algorithms other than HMAC-MD5 because we weren't passing the
right digest module to the HMAC code. Thanks to salzmdan for
reporting the bug.
2013-08-09 Bob Halley <[email protected]>
* dns/dnssec.py (_find_candidate_keys): we tried to extract the
key from the wrong variable name. Thanks to Andrei Fokau for the
fix.
2013-07-08 Bob Halley <[email protected]>
* dns/resolver.py: we want 'self.retry_servfail' not just
retry_servfail. Reported by many, thanks! Thanks to
Jeffrey C. Ollie for the fix.
2013-07-08 Bob Halley <[email protected]>
* tests/grange.py: fix tests to use older-style print formatting
for backwards compatibility with python 2.4. Thanks to
Jeffrey C. Ollie for the fix.
2013-07-01 Bob Halley <[email protected]>
* (Version 1.11.0 released)
2013-04-28 Bob Halley <[email protected]>
* dns/name.py (Name.to_wire): Do not add items with offsets >= 2^14
to the compression table. Thanks to Casey Deccio for discovering
this bug.
2013-04-26 Bob Halley <[email protected]>
* dns/ipv6.py (inet_ntoa): We now comply with RFC 5952 section
5.2.2, by *not* using the :: syntax to shorten just one 16-bit
field. Thanks to David Waitzman for reporting the bug and
suggesting the fix.
2013-03-31 Bob Halley <[email protected]>
* lock caches in case they are shared
* raise YXDOMAIN if we see one
* do not print empty rdatasets
* Add contributed $GENERATE support (thanks uberj)
* Remove DNSKEY keytag uniqueness assumption (RFC 4034, section 8)
(thanks James Dempsey)
2012-09-25 Sean Leach
* added set_flags() method to dns.resolver.Resolver
2012-09-25 Pieter Lexis
* added support for TLSA RR
2012-08-28 Bob Halley <[email protected]>
* dns/rdtypes/ANY/NSEC3.py (NSEC3.from_text): The NSEC3 from_text()
method could erroneously emit empty bitmap windows (i.e. windows
with a count of 0 bytes); such bitmaps are illegal.
2012-04-08 Bob Halley <[email protected]>
* (Version 1.10.0 released)
2012-04-08 Bob Halley <[email protected]>
* dns/message.py (make_query): All EDNS values may now be
specified when calling make_query()
* dns/query.py: Specifying source_port had no effect if source was
not specified. We now use the appropriate wildcard source in
that case.
* dns/resolver.py (Resolver.query): source_port may now be
specified.
* dns/resolver.py (Resolver.query): Switch to TCP when a UDP
response is truncated. Handle nameservers that serve on UDP
but not TCP.
2012-04-07 Bob Halley <[email protected]>
* dns/zone.py (from_xfr): dns.zone.from_xfr() now takes a
'check_origin' parameter which defaults to True. If set to
False, then dnspython will not make origin checks on the zone.
Thanks to Carlos Perez for the report.
* dns/rdtypes/ANY/SSHFP.py (SSHFP.from_text): Allow whitespace in
the text string. Thanks to Jan Andres for the report and the
patch.
* dns/message.py (from_wire): dns.message.from_wire() now takes
an 'ignore_trailing' parameter which defaults to False. If set
to True, then trailing junk will be ignored instead of causing
TrailingJunk to be raised. Thanks to Shane Huntley for
contributing the patch.
2011-08-22 Bob Halley <[email protected]>
* dns/resolver.py: Added LRUCache. In this cache implementation,
the cache size is limited to a user-specified number of nodes, and
when adding a new node to a full cache the least-recently used
node is removed.
2011-07-13 Bob Halley <[email protected]>
* dns/resolver.py: dns.resolver.override_system_resolver()
overrides the socket module's versions of getaddrinfo(),
getnameinfo(), getfqdn(), gethostbyname(), gethostbyname_ex() and
gethostbyaddr() with an implementation which uses a dnspython stub
resolver instead of the system's stub resolver. This can be
useful in testing situations where you want to control the
resolution behavior of python code without having to change the
system's resolver settings (e.g. /etc/resolv.conf).
dns.resolver.restore_system_resolver() undoes the change.
2011-07-08 Bob Halley <[email protected]>
* dns/ipv4.py: dnspython now provides its own, stricter, versions
of IPv4 inet_ntoa() and inet_aton() instead of using the OS's
versions.
* dns/ipv6.py: inet_aton() now bounds checks embedded IPv4 addresses
more strictly. Also, now only dns.exception.SyntaxError can be
raised on bad input.
2011-04-05 Bob Halley <[email protected]>
* Old DNSSEC types (KEY, NXT, and SIG) have been removed.
* Bounds checking of slices in rdata wire processing is now more
strict, and bounds errors (e.g. we got less data than was
expected) now raise dns.exception.FormError rather than
IndexError.
2011-03-28 Bob Halley <[email protected]>
* (Version 1.9.4 released)
2011-03-24 Bob Halley <[email protected]>
* dns/rdata.py (Rdata._wire_cmp): We need to specify no
compression and an origin to _wire_cmp() in case names in the
rdata are relative names.
* dns/rdtypes/ANY/SIG.py (SIG._cmp): Add missing 'import struct'.
Thanks to Arfrever Frehtes Taifersar Arahesis for reporting the
problem.
2011-03-24 Bob Halley <[email protected]>
* (Version 1.9.3 released)
2011-03-22 Bob Halley <[email protected]>
* dns/resolver.py: a boolean parameter, 'raise_on_no_answer', has
been added to the query() methods. In no-error, no-data
situations, this parameter determines whether NoAnswer should be
raised or not. If True, NoAnswer is raised. If False, then an
Answer() object with a None rrset will be returned.
* dns/resolver.py: Answer() objects now have a canonical_name field.
2011-01-11 Bob Halley <[email protected]>
* Dnspython was erroneously doing case-insensitive comparisons
of the names in NSEC and RRSIG RRs. Thanks to Casey Deccio for
reporting this bug.
2010-12-17 Bob Halley <[email protected]>
* dns/message.py (_WireReader._get_section): use "is" and not "=="
when testing what section an RR is in. Thanks to James Raftery
for reporting this bug.
2010-12-10 Bob Halley <[email protected]>
* dns/resolver.py (Resolver.query): disallow metaqueries.
* dns/rdata.py (Rdata.__hash__): Added a __hash__ method for rdata.
2010-11-23 Bob Halley <[email protected]>
* (Version 1.9.2 released)
2010-11-23 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.9.1 released)
2010-11-22 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.9.0 released)
2010-11-07 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.8.0 released)
2010-01-13 Bob Halley <[email protected]>
* dns/dnssec.py: Added RSASHA256 and RSASHA512 codepoints; added
other missing codepoints to _algorithm_by_text.
2010-01-12 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.7.1 released)
2009-06-19 Bob Halley <[email protected]>
* DLV.py was omitted from the kit
* Negative prerequisites were not handled correctly in _get_section().
2009-06-19 Bob Halley <[email protected]>
* (Version 1.7.0 released)
2009-06-19 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* dns/query.py (xfr): Allow UDP IXFRs. Use "one_rr_per_rrset" mode when
doing IXFR.
2009-03-30 Bob Halley <[email protected]>
* 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 <[email protected]>
* Added EDNS option support.
2008-10-16 Bob Halley <[email protected]>
* 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 <[email protected]>
* Add entropy module.
* When validating TSIGs, we need to use the absolute name.
2008-06-03 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.6.0 released)
2007-11-25 Bob Halley <[email protected]>
* dns/query.py (_wait_for): if select() raises an exception due to
EINTR, we should just select() again.
2007-06-13 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/rdtypes/IN/NAPTR.py: NAPTR comparisons didn't compare the
preference field due to a typo.
2007-02-07 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.5.0 released)
2006-11-03 Bob Halley <[email protected]>
* dns/rdtypes/IN/DHCID.py: Added support for the DHCID RR type.
2006-11-02 Bob Halley <[email protected]>
* dns/query.py (udp): Messages from unexpected sources can now be
ignored by setting ignore_unexpected to True.
2006-10-31 Bob Halley <[email protected]>
* dns/query.py (udp): When raising UnexpectedSource, add more
detail about what went wrong to the exception.
2006-09-22 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* dns/query.py (xfr): Add IXFR support.
2006-06-22 Bob Halley <[email protected]>
* dns/rdtypes/IN/IPSECKEY.py: Added support for the IPSECKEY RR type.
2006-06-21 Bob Halley <[email protected]>
* dns/rdtypes/ANY/SPF.py: Added support for the SPF RR type.
2006-06-02 Bob Halley <[email protected]>
* (Version 1.4.0 released)
2006-04-25 Bob Halley <[email protected]>
* dns/rrset.py (RRset.to_rdataset): Added a convenience method
to convert an rrset into an rdataset.
2006-03-27 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/resolver.py (Resolver.query): The resolver deleted from
a list while iterating it, which makes the iterator unhappy.
2006-03-17 Bob Halley <[email protected]>
* dns/resolver.py (Resolver.query): The resolver needlessly
delayed responses for successful queries.
2006-01-18 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.3.5 released)
2005-10-12 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/name.py: Added the parent() method, which returns the
parent of a name.
2005-10-01 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/resolver.py (Resolver._compute_timeout): If time goes
backwards a little bit, ignore it.
2005-07-31 Bob Halley <[email protected]>
* (Version 1.3.4 released)
2005-07-31 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/query.py: The requirement that the "where" parameter be
an IPv4 or IPv6 address is now documented.
2005-06-04 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.3.3 released)
2004-10-25 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.3.2 released)
2004-08-04 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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.

* 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 <[email protected]>
* 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 <[email protected]>
* dns/name.py (from_text): dns.name.from_text() did not raise
an exception if a backslash escape ended prematurely.
