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.
2004-06-06 Bob Halley <[email protected]>
* (Version 1.3.1 released)
2004-05-22 Bob Halley <[email protected]>
* 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.
2004-04-09 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.3.0 released)
2004-03-19 Bob Halley <[email protected]>
* Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.
2004-01-16 Bob Halley <[email protected]>
* dns/query.py (_connect): Windows returns EWOULDBLOCK instead
of EINPROGRESS when trying to connect a nonblocking socket.
2003-11-13 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.2.0 released)
2003-11-03 Bob Halley <[email protected]>
* dns/zone.py (_MasterReader.read): The saved_state now includes
the default TTL.
2003-11-01 Bob Halley <[email protected]>
* dns/tokenizer.py (Tokenizer.get): The tokenizer didn't
handle escaped delimiters.
2003-10-27 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.2.0b1 released)
2003-09-05 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/zone.py: dns.exception.SyntaxError is raised for unknown
master file directives.
2003-08-28 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/zone.py: The _MasterReader now understands $INCLUDE.
2003-08-12 Bob Halley <[email protected]>
* 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 <[email protected]>
* (Version 1.1.0 released)
2003-08-07 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* Node and all rdata types have been "slotted". This speeds
things up a little and reduces memory usage noticeably.
2003-08-02 Bob Halley <[email protected]>
* (Version 1.1.0c1 released)
2003-08-02 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* (Version 1.1.0b2 released)
2003-07-30 Bob Halley <[email protected]>
* 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 <[email protected]>
* dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses.
2003-07-19 Bob Halley <[email protected]>
* (Version 1.1.0b1 released)
2003-07-18 Bob Halley <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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 <[email protected]>
* 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.

* 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.

* 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.

* 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
