1 2010-12-17 Bob Halley <halley@dnspython.org>
3 * dns/message.py (_WireReader._get_section): use "is" and not "=="
4 when testing what section an RR is in. Thanks to James Raftery
5 for reporting this bug.
7 2010-12-10 Bob Halley <halley@dnspython.org>
9 * dns/resolver.py (Resolver.query): disallow metaqueries.
11 * dns/rdata.py (Rdata.__hash__): Added a __hash__ method for rdata.
13 2010-11-23 Bob Halley <halley@dnspython.org>
15 * (Version 1.9.2 released)
17 2010-11-23 Bob Halley <halley@dnspython.org>
19 * dns/dnssec.py (_need_pycrypto): DSA and RSA are modules, not
20 functions, and I didn't notice because the test suite masked
23 2010-11-22 Bob Halley <halley@dnspython.org>
25 * (Version 1.9.1 released)
27 2010-11-22 Bob Halley <halley@dnspython.org>
29 * dns/dnssec.py: the "from" style import used to get DSA from
30 PyCrypto trashed a DSA constant. Now a normal import is used
31 to avoid namespace contamination.
33 2010-11-20 Bob Halley <halley@dnspython.org>
35 * (Version 1.9.0 released)
37 2010-11-07 Bob Halley <halley@dnspython.org>
39 * dns/dnssec.py: Added validate() to do basic DNSSEC validation
40 (requires PyCrypto). Thanks to Brian Wellington for the patch.
42 * dns/hash.py: Hash compatibility handling is now its own module.
44 2010-10-31 Bob Halley <halley@dnspython.org>
46 * dns/resolver.py (zone_for_name): A query name resulting in a
47 CNAME or DNAME response to a node which had an SOA was incorrectly
48 treated as a zone origin. In these cases, we should just look
49 higher. Thanks to Gert Berger for reporting this problem.
51 * Added zonediff.py to examples. This program compares two zones
52 and shows the differences either in diff-like plain text, or
53 HTML. Thanks to Dennis Kaarsemaker for contributing this
56 2010-10-27 Bob Halley <halley@dnspython.org>
58 * Incorporate a patch to use poll() instead of select() by
59 default on platforms which support it. Thanks to
60 Peter Schüller and Spotify for the contribution.
62 2010-10-17 Bob Halley <halley@dnspython.org>
64 * Python prior to 2.5.2 doesn't compute the correct values for
65 HMAC-SHA384 and HMAC-SHA512. We now detect attempts to use
66 them and raise NotImplemented if the Python version is too old.
67 Thanks to Kevin Chen for reporting the problem.
69 * Various routines that took the string forms of rdata types and
70 classes did not permit the strings to be Unicode strings.
71 Thanks to Ryan Workman for reporting the issue.
73 * dns/tsig.py: Added symbolic constants for the algorithm strings.
74 E.g. you can now say dns.tsig.HMAC_MD5 instead of
75 "HMAC-MD5.SIG-ALG.REG.INT". Thanks to Cillian Sharkey for
76 suggesting this improvement.
78 * dns/tsig.py (get_algorithm): fix hashlib compatibility; thanks to
79 Kevin Chen for the patch.
81 * dns/dnssec.py: Added key_id() and make_ds().
83 * dns/message.py: message.py needs to import dns.edns since it uses
86 2010-05-04 Bob Halley <halley@dnspython.org>
88 * dns/rrset.py (RRset.__init__): "covers" was not passed to the
89 superclass __init__(). Thanks to Shanmuga Rajan for reporting
92 2010-03-10 Bob Halley <halley@dnspython.org>
94 * The TSIG algorithm value was passed to use_tsig() incorrectly
95 in some cases. Thanks to 'ducciovigolo' for reporting the problem.
97 2010-01-26 Bob Halley <halley@dnspython.org>
99 * (Version 1.8.0 released)
101 2010-01-13 Bob Halley <halley@dnspython.org>
103 * dns/dnssec.py: Added RSASHA256 and RSASHA512 codepoints; added
104 other missing codepoints to _algorithm_by_text.
106 2010-01-12 Bob Halley <halley@dnspython.org>
108 * Escapes in masterfiles now work correctly. Previously they were
109 only working correctly when the text involved was part of a domain
112 * dns/tokenizer.py: The tokenizer's get() method now returns Token
113 objects, not (type, text) tuples.
115 2009-11-13 Bob Halley <halley@dnspython.org>
117 * Support has been added for hmac-sha1, hmac-sha224, hmac-sha256,
118 hmac-sha384 and hmac-sha512. Thanks to Kevin Chen for a
119 thoughtful, high quality patch.
121 * dns/update.py (Update::present): A zero TTL was not added if
122 present() was called with a single rdata, causing _add() to be
123 unhappy. Thanks to Eugene Kim for reporting the problem and
126 * dns/entropy.py: Use os.urandom() if present. Don't seed until
127 someone wants randomness.
129 2009-09-16 Bob Halley <halley@dnspython.org>
131 * dns/entropy.py: The entropy module needs locking in order to be
132 used safely in a multithreaded environment. Thanks to Beda Kosata
133 for reporting the problem.
135 2009-07-27 Bob Halley <halley@dnspython.org>
137 * dns/query.py (xfr): The socket was not set to nonblocking mode.
138 Thanks to Erik Romijn for reporting this problem.
140 2009-07-23 Bob Halley <halley@dnspython.org>
142 * dns/rdtypes/IN/SRV.py (SRV._cmp): SRV records were compared
143 incorrectly due to a cut-and-paste error. Thanks to Tommie
144 Gannert for reporting this bug.
146 * dns/e164.py (query): The resolver parameter was not used.
147 Thanks to Matías Bellone for reporting this bug.
149 2009-06-23 Bob Halley <halley@dnspython.org>
151 * dns/entropy.py (EntropyPool.__init__): open /dev/random unbuffered;
152 there's no need to consume more randomness than we need. Thanks
153 to Brian Wellington for the patch.
155 2009-06-19 Bob Halley <halley@dnspython.org>
157 * (Version 1.7.1 released)
159 2009-06-19 Bob Halley <halley@dnspython.org>
161 * DLV.py was omitted from the kit
163 * Negative prerequisites were not handled correctly in _get_section().
165 2009-06-19 Bob Halley <halley@dnspython.org>
167 * (Version 1.7.0 released)
169 2009-06-19 Bob Halley <halley@dnspython.org>
171 * On Windows, the resolver set the domain incorrectly. Thanks
172 to Brandon Carpenter for reporting this bug.
174 * Added a to_digestable() method to rdata classes; it returns the
175 digestable form (i.e. DNSSEC canonical form) of the rdata. For
176 most rdata types this is the same uncompressed wire form. For
177 certain older DNS RR types, however, domain names in the rdata
180 * Added support for the HIP RR type.
182 2009-06-18 Bob Halley <halley@dnspython.org>
184 * Added support for the DLV RR type.
186 * Added various DNSSEC related constants (e.g. algorithm identifiers,
189 * dns/tsig.py: Added support for BADTRUNC result code.
191 * dns/query.py (udp): When checking that addresses are the same,
192 use the binary form of the address in the comparison. This
193 ensures that we don't treat addresses as different if they have
194 equivalent but differing textual representations. E.g. "1:00::1"
195 and "1::1" represent the same address but are not textually equal.
196 Thanks to Kim Davies for reporting this bug.
198 * The resolver's query() method now has an optional 'source' parameter,
199 allowing the source IP address to be specified. Thanks to
200 Alexander Lind for suggesting the change and sending a patch.
202 * Added NSEC3 and NSEC3PARAM support.
204 2009-06-17 Bob Halley <halley@dnspython.org>
206 * Fixed NSEC.to_text(), which was only printing the last window.
207 Thanks to Brian Wellington for finding the problem and fixing it.
209 2009-03-30 Bob Halley <halley@dnspython.org>
211 * dns/query.py (xfr): Allow UDP IXFRs. Use "one_rr_per_rrset" mode when
214 2009-03-30 Bob Halley <halley@dnspython.org>
216 * Add "one_rr_per_rrset" mode switch to methods which parse
217 messages from wire format (e.g. dns.message.from_wire(),
218 dns.query.udp(), dns.query.tcp()). If set, each RR read is
219 placed in its own RRset (instead of being coalesced).
221 2009-03-30 Bob Halley <halley@dnspython.org>
223 * Added EDNS option support.
225 2008-10-16 Bob Halley <halley@dnspython.org>
227 * dns/rdtypes/ANY/DS.py: The from_text() parser for DS RRs did not
228 allow multiple Base64 chunks. Thanks to Rakesh Banka for
229 finding this bug and submitting a patch.
231 2008-10-08 Bob Halley <halley@dnspython.org>
233 * Add entropy module.
235 * When validating TSIGs, we need to use the absolute name.
237 2008-06-03 Bob Halley <halley@dnspython.org>
239 * dns/message.py (Message.set_rcode): The mask used preserved the
240 extended rcode, instead of everything else in ednsflags.
242 * dns/message.py (Message.use_edns): ednsflags was not kept
243 coherent with the specified edns version.
245 2008-02-06 Bob Halley <halley@dnspython.org>
247 * dns/ipv6.py (inet_aton): We could raise an exception other than
248 dns.exception.SyntaxError in some cases.
250 * dns/tsig.py: Raise an exception when the peer has set a non-zero
253 2007-11-25 Bob Halley <halley@dnspython.org>
255 * (Version 1.6.0 released)
257 2007-11-25 Bob Halley <halley@dnspython.org>
259 * dns/query.py (_wait_for): if select() raises an exception due to
260 EINTR, we should just select() again.
262 2007-06-13 Bob Halley <halley@dnspython.org>
264 * dns/inet.py: Added is_multicast().
266 * dns/query.py (udp): If the queried address is a multicast address, then
267 don't check that the address of the response is the same as the address
270 2007-05-24 Bob Halley <halley@dnspython.org>
272 * dns/rdtypes/IN/NAPTR.py: NAPTR comparisons didn't compare the
273 preference field due to a typo.
275 2007-02-07 Bob Halley <halley@dnspython.org>
277 * dns/resolver.py: Integrate code submitted by Paul Marks to
278 determine whether a Windows NIC is enabled. The way dnspython
279 used to do this does not work on Windows Vista.
281 2006-12-10 Bob Halley <halley@dnspython.org>
283 * (Version 1.5.0 released)
285 2006-11-03 Bob Halley <halley@dnspython.org>
287 * dns/rdtypes/IN/DHCID.py: Added support for the DHCID RR type.
289 2006-11-02 Bob Halley <halley@dnspython.org>
291 * dns/query.py (udp): Messages from unexpected sources can now be
292 ignored by setting ignore_unexpected to True.
294 2006-10-31 Bob Halley <halley@dnspython.org>
296 * dns/query.py (udp): When raising UnexpectedSource, add more
297 detail about what went wrong to the exception.
299 2006-09-22 Bob Halley <halley@dnspython.org>
301 * dns/message.py (Message.use_edns): add reasonable defaults for
302 the ednsflags, payload, and request_payload parameters.
304 * dns/message.py (Message.want_dnssec): add a convenience method for
305 enabling/disabling the "DNSSEC desired" flag in requests.
307 * dns/message.py (make_query): add "use_edns" and "want_dnssec"
310 2006-08-17 Bob Halley <halley@dnspython.org>
312 * dns/resolver.py (Resolver.read_resolv_conf): If /etc/resolv.conf
313 doesn't exist, just use the default resolver configuration (i.e.
314 the same thing we would have used if resolv.conf had existed and
317 2006-07-26 Bob Halley <halley@dnspython.org>
319 * dns/resolver.py (Resolver._config_win32_fromkey): fix
320 cut-and-paste error where we passed the wrong variable to
321 self._config_win32_search(). Thanks to David Arnold for finding
322 the bug and submitting a patch.
324 2006-07-20 Bob Halley <halley@dnspython.org>
326 * dns/resolver.py (Answer): Add more support for the sequence
327 protocol, forwarding requests to the answer object's rrset.
328 E.g. "for a in answer" is equivalent to "for a in answer.rrset",
329 "answer[i]" is equivalent to "answer.rrset[i]", and
330 "answer[i:j]" is equivalent to "answer.rrset[i:j]".
332 2006-07-19 Bob Halley <halley@dnspython.org>
334 * dns/query.py (xfr): Add IXFR support.
336 2006-06-22 Bob Halley <halley@dnspython.org>
338 * dns/rdtypes/IN/IPSECKEY.py: Added support for the IPSECKEY RR type.
340 2006-06-21 Bob Halley <halley@dnspython.org>
342 * dns/rdtypes/ANY/SPF.py: Added support for the SPF RR type.
344 2006-06-02 Bob Halley <halley@dnspython.org>
346 * (Version 1.4.0 released)
348 2006-04-25 Bob Halley <halley@dnspython.org>
350 * dns/rrset.py (RRset.to_rdataset): Added a convenience method
351 to convert an rrset into an rdataset.
353 2006-03-27 Bob Halley <halley@dnspython.org>
355 * Added dns.e164.query(). This function can be used to look for
356 NAPTR RRs for a specified number in several domains, e.g.:
358 dns.e164.query('16505551212',
359 ['e164.dnspython.org.', 'e164.arpa.'])
361 2006-03-26 Bob Halley <halley@dnspython.org>
363 * dns/resolver.py (Resolver.query): The resolver deleted from
364 a list while iterating it, which makes the iterator unhappy.
366 2006-03-17 Bob Halley <halley@dnspython.org>
368 * dns/resolver.py (Resolver.query): The resolver needlessly
369 delayed responses for successful queries.
371 2006-01-18 Bob Halley <halley@dnspython.org>
373 * dns/rdata.py: added a validate() method to the rdata class. If
374 you change an rdata by assigning to its fields, it is a good
375 idea to call validate() when you are done making changes.
376 For example, if 'r' is an MX record and then you execute:
378 r.preference = 100000 # invalid, because > 65535
381 The validation will fail and an exception will be raised.
383 2006-01-11 Bob Halley <halley@dnspython.org>
385 * dns/ttl.py: TTLs are now bounds checked to be within the closed
386 interval [0, 2^31 - 1].
388 * The BIND 8 TTL syntax is now accepted in the SOA refresh, retry,
389 expire, and minimum fields, and in the original_ttl field of
390 SIG and RRSIG records.
392 2006-01-04 Bob Halley <halley@dnspython.org>
394 * dns/resolver.py: The windows registry irritatingly changes the
395 list element delimiter in between ' ' and ',' (and vice-versa)
396 in various versions of windows. We now cope by always looking
397 for either one (' ' first).
399 2005-12-27 Bob Halley <halley@dnspython.org>
401 * dns/e164.py: Added routines to convert between E.164 numbers and
402 their ENUM domain name equivalents.
404 * dns/reversename.py: Added routines to convert between IPv4 and
405 IPv6 addresses and their DNS reverse-map equivalents.
407 2005-12-18 Bob Halley <halley@dnspython.org>
409 * dns/rdtypes/ANY/LOC.py (_tuple_to_float): The sign was lost when
410 converting a tuple into a float, which broke conversions of
411 south latitudes and west longitudes.
413 2005-11-17 Bob Halley <halley@dnspython.org>
415 * dns/zone.py: The 'origin' parameter to from_text() and from_file()
416 is now optional. If not specified, dnspython will use the
417 first $ORIGIN in the text as the zone's origin.
419 * dns/zone.py: Sanity checks of the zone's origin node can now
422 2005-11-12 Bob Halley <halley@dnspython.org>
424 * dns/name.py: Preliminary Unicode support has been added for
425 domain names. Running dns.name.from_text() on a Unicode string
426 will now encode each label using the IDN ACE encoding. The
427 to_unicode() method may be used to convert a dns.name.Name with
428 IDN ACE labels back into a Unicode string. This functionality
429 requires Python 2.3 or greater.
431 2005-10-31 Bob Halley <halley@dnspython.org>
433 * (Version 1.3.5 released)
435 2005-10-12 Bob Halley <halley@dnspython.org>
437 * dns/zone.py: Zone.iterate_rdatasets() and Zone.iterate_rdatas()
438 did not have a default rdtype of dns.rdatatype.ANY as their
439 docstrings said they did. They do now.
441 2005-10-06 Bob Halley <halley@dnspython.org>
443 * dns/name.py: Added the parent() method, which returns the
446 2005-10-01 Bob Halley <halley@dnspython.org>
448 * dns/resolver.py: Added zone_for_name() helper, which returns
449 the name of the zone which contains the specified name.
451 * dns/resolver.py: Added get_default_resolver(), which returns
452 the default resolver, initializing it if necessary.
454 2005-09-29 Bob Halley <halley@dnspython.org>
456 * dns/resolver.py (Resolver._compute_timeout): If time goes
457 backwards a little bit, ignore it.
459 2005-07-31 Bob Halley <halley@dnspython.org>
461 * (Version 1.3.4 released)
463 2005-07-31 Bob Halley <halley@dnspython.org>
465 * dns/message.py (make_response): Trying to respond to a response
466 threw a NameError while trying to throw a FormErr since it used
467 the wrong name for the FormErr exception.
469 * dns/query.py (_connect): We needed to ignore EALREADY too.
471 * dns/query.py: Optional "source" and "source_port" parameters
472 have been added to udp(), tcp(), and xfr(). Thanks to Ralf
473 Weber for suggesting the change and providing a patch.
475 2005-06-05 Bob Halley <halley@dnspython.org>
477 * dns/query.py: The requirement that the "where" parameter be
478 an IPv4 or IPv6 address is now documented.
480 2005-06-04 Bob Halley <halley@dnspython.org>
482 * dns/resolver.py: The resolver now does exponential backoff
483 each time it runs through all of the nameservers.
485 * dns/resolver.py: rcodes which indicate a nameserver is likely
486 to be a "permanent failure" for a query cause the nameserver
487 to be removed from the mix for that query.
489 2005-01-30 Bob Halley <halley@dnspython.org>
491 * (Version 1.3.3 released)
493 2004-10-25 Bob Halley <halley@dnspython.org>
495 * dns/rdtypes/ANY/TXT.py (TXT.from_text): The masterfile parser
496 incorrectly rejected TXT records where a value was not quoted.
498 2004-10-11 Bob Halley <halley@dnspython.org>
500 * dns/message.py: Added make_response(), which creates a skeletal
501 response for the specified query. Added opcode() and set_opcode()
502 convenience methods to the Message class. Added the request_payload
503 attribute to the Message class.
505 2004-10-10 Bob Halley <halley@dnspython.org>
507 * dns/zone.py (from_xfr): dns.zone.from_xfr() in relativization
508 mode incorrectly set zone.origin to the empty name.
510 2004-09-02 Bob Halley <halley@dnspython.org>
512 * dns/name.py (Name.to_wire): The 'file' parameter to
513 Name.to_wire() is now optional; if omitted, the wire form will
514 be returned as the value of the function.
516 2004-08-14 Bob Halley <halley@dnspython.org>
518 * dns/message.py (Message.find_rrset): find_rrset() now uses an
519 index, vastly improving the from_wire() performance of large
520 messages such as zone transfers.
522 2004-08-07 Bob Halley <halley@dnspython.org>
524 * (Version 1.3.2 released)
526 2004-08-04 Bob Halley <halley@dnspython.org>
528 * dns/query.py: sending queries to a nameserver via IPv6 now
531 * dns/inet.py (af_for_address): Add af_for_address(), which looks
532 at a textual-form address and attempts to determine which address
535 * dns/query.py: the default for the 'af' parameter of the udp(),
536 tcp(), and xfr() functions has been changed from AF_INET to None,
537 which causes dns.inet.af_for_address() to be used to determine the
538 address family. If dns.inet.af_for_address() can't figure it out,
539 we fall back to AF_INET and hope for the best.
541 2004-07-31 Bob Halley <halley@dnspython.org>
543 * dns/rdtypes/ANY/NSEC.py (NSEC.from_text): The NSEC text format
544 does not allow specifying types by number, so we shouldn't either.
546 * dns/renderer.py: the renderer module didn't import random,
547 causing an exception to be raised if a query id wasn't provided
548 when a Renderer was created.
550 * dns/resolver.py (Resolver.query): the resolver wasn't catching
551 dns.exception.Timeout, so a timeout erroneously caused the whole
552 resolution to fail instead of just going on to the next server.
554 2004-06-16 Bob Halley <halley@dnspython.org>
556 * dns/rdtypes/ANY/LOC.py (LOC.from_text): LOC milliseconds values
557 were converted incorrectly if the length of the milliseconds
558 string was less than 3.
560 2004-06-06 Bob Halley <halley@dnspython.org>
562 * (Version 1.3.1 released)
564 2004-05-22 Bob Halley <halley@dnspython.org>
566 * dns/update.py (Update.delete): We erroneously specified a
567 "deleting" value of dns.rdatatype.NONE instead of
568 dns.rdataclass.NONE when the thing being deleted was either an
569 Rdataset instance or an Rdata instance.
571 * dns/rdtypes/ANY/SSHFP.py: Added support for the proposed SSHFP
574 2004-05-14 Bob Halley <halley@dnspython.org>
576 * dns/rdata.py (from_text): The masterfile reader did not
577 accept the unknown RR syntax when used with a known RR type.
579 2004-05-08 Bob Halley <halley@dnspython.org>
581 * dns/name.py (from_text): dns.name.from_text() did not raise
582 an exception if a backslash escape ended prematurely.
584 2004-04-09 Bob Halley <halley@dnspython.org>
586 * dns/zone.py (_MasterReader._rr_line): The masterfile reader
587 erroneously treated lines starting with leading whitespace but
588 not having any RR definition as an error. It now treats
589 them like a blank line (which is not an error).
591 2004-04-01 Bob Halley <halley@dnspython.org>
593 * (Version 1.3.0 released)
595 2004-03-19 Bob Halley <halley@dnspython.org>
597 * Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY.
599 2004-01-16 Bob Halley <halley@dnspython.org>
601 * dns/query.py (_connect): Windows returns EWOULDBLOCK instead
602 of EINPROGRESS when trying to connect a nonblocking socket.
604 2003-11-13 Bob Halley <halley@dnspython.org>
606 * dns/rdtypes/ANY/LOC.py (LOC.to_wire): We encoded and decoded LOC
607 incorrectly, since we were interpreting the values of altitiude,
608 size, hprec, and vprec in meters instead of centimeters.
610 * dns/rdtypes/IN/WKS.py (WKS.from_wire): The WKS protocol value is
611 encoded with just one octet, not two!
613 2003-11-09 Bob Halley <halley@dnspython.org>
615 * dns/resolver.py (Cache.maybe_clean): The cleaner deleted items
616 from the dictionary while iterating it, causing a RuntimeError
617 to be raised. Thanks to Mark R. Levinson for the bug report,
618 regression test, and fix.
620 2003-11-07 Bob Halley <halley@dnspython.org>
622 * (Version 1.2.0 released)
624 2003-11-03 Bob Halley <halley@dnspython.org>
626 * dns/zone.py (_MasterReader.read): The saved_state now includes
629 2003-11-01 Bob Halley <halley@dnspython.org>
631 * dns/tokenizer.py (Tokenizer.get): The tokenizer didn't
632 handle escaped delimiters.
634 2003-10-27 Bob Halley <halley@dnspython.org>
636 * dns/resolver.py (Resolver.read_resolv_conf): If no nameservers
637 are configured in /etc/resolv.conf, the default nameserver
638 list should be ['127.0.0.1'].
640 2003-09-08 Bob Halley <halley@dnspython.org>
642 * dns/resolver.py (Resolver._config_win32_fromkey): We didn't
643 catch WindowsError, which can happen if a key is not defined
646 2003-09-06 Bob Halley <halley@dnspython.org>
648 * (Version 1.2.0b1 released)
650 2003-09-05 Bob Halley <halley@dnspython.org>
652 * dns/query.py: Timeout support has been overhauled to provide
653 timeouts under Python 2.2 as well as 2.3, and to provide more
656 2003-08-30 Bob Halley <halley@dnspython.org>
658 * dns/zone.py: dns.exception.SyntaxError is raised for unknown
659 master file directives.
661 2003-08-28 Bob Halley <halley@dnspython.org>
663 * dns/zone.py: $INCLUDE processing is now enabled/disabled using
664 the allow_include parameter. The default is to process $INCLUDE
665 for from_file(), and to disallow $INCLUDE for from_text(). The
666 master reader now calls zone.check_origin_node() by default after
667 the zone has been read. find_rdataset() called get_node() instead
668 of find_node(), which result in an incorrect exception. The
669 relativization state of a zone is now remembered and applied
670 consistently when looking up names. from_xfr() now supports
671 relativization like the _MasterReader.
673 2003-08-22 Bob Halley <halley@dnspython.org>
675 * dns/zone.py: The _MasterReader now understands $INCLUDE.
677 2003-08-12 Bob Halley <halley@dnspython.org>
679 * dns/zone.py: The _MasterReader now specifies the file and line
680 number when a syntax error occurs. The BIND 8 TTL format is now
681 understood when loading a zone, though it will never be emitted.
682 The from_file() function didn't pass the zone_factory parameter
685 2003-08-10 Bob Halley <halley@dnspython.org>
687 * (Version 1.1.0 released)
689 2003-08-07 Bob Halley <halley@dnspython.org>
691 * dns/update.py (Update._add): A typo meant that _add would
692 fail if the thing being added was an Rdata object (as
693 opposed to an Rdataset or the textual form of an Rdata).
695 2003-08-05 Bob Halley <halley@dnspython.org>
697 * dns/set.py: the simple Set class has been moved to its
698 own module, and augmented to support more set operations.
700 2003-08-04 Bob Halley <halley@dnspython.org>
702 * Node and all rdata types have been "slotted". This speeds
703 things up a little and reduces memory usage noticeably.
705 2003-08-02 Bob Halley <halley@dnspython.org>
707 * (Version 1.1.0c1 released)
709 2003-08-02 Bob Halley <halley@dnspython.org>
711 * dns/rdataset.py: SimpleSets now support more set options.
713 * dns/message.py: Added the get_rrset() method. from_file() now
714 allows Unicode filenames and turns on universal newline support if
715 it opens the file itself.
717 * dns/node.py: Added the delete_rdataset() and replace_rdataset()
720 * dns/zone.py: Added the delete_node(), delete_rdataset(), and
721 replace_rdataset() methods. from_file() now allows Unicode
722 filenames and turns on universal newline support if it opens the
723 file itself. Added a to_file() method.
725 2003-08-01 Bob Halley <halley@dnspython.org>
727 * dns/opcode.py: Opcode from/to text converters now understand
728 numeric opcodes. The to_text() method will return a numeric opcode
729 string if it doesn't know a text name for the opcode.
731 * dns/message.py: Added set_rcode(). Fixed code where ednsflags
732 wasn't treated as a long.
734 * dns/rcode.py: ednsflags wasn't treated as a long. Rcode from/to
735 text converters now understand numeric rcodes. The to_text()
736 method will return a numeric rcode string if it doesn't know
737 a text name for the rcode.
739 * examples/reverse.py: Added a new example program that builds a
740 reverse (address-to-name) mapping table from the name-to-address
741 mapping specified by A RRs in zone files.
743 * dns/node.py: Added get_rdataset() method.
745 * dns/zone.py: Added get_rdataset() and get_rrset() methods. Added
748 2003-07-31 Bob Halley <halley@dnspython.org>
750 * dns/zone.py: Added the iterate_rdatasets() method which returns
751 a generator which yields (name, rdataset) tuples for all the
752 rdatasets in the zone matching the specified rdatatype.
754 2003-07-30 Bob Halley <halley@dnspython.org>
756 * (Version 1.1.0b2 released)
758 2003-07-30 Bob Halley <halley@dnspython.org>
760 * dns/zone.py: Added find_rrset() and find_rdataset() convenience
761 methods. They let you retrieve rdata with the specified name
762 and type in one call.
764 * dns/node.py: Nodes no longer have names; owner names are
765 associated with nodes in the Zone object's nodes dictionary.
767 * dns/zone.py: Zone objects now implement more of the standard
768 mapping interface. __iter__ has been changed to iterate the keys
769 rather than values to match the standard mapping interface's
772 2003-07-20 Bob Halley <halley@dnspython.org>
774 * dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses.
776 2003-07-19 Bob Halley <halley@dnspython.org>
778 * (Version 1.1.0b1 released)
780 2003-07-18 Bob Halley <halley@dnspython.org>
782 * dns/tsig.py: The TSIG validation of TCP streams where not
783 every message is signed now works correctly.
785 * dns/zone.py: Zones can now be compared for equality and
786 inequality. If the other object in the comparison is also
787 a zone, then "the right thing" happens; i.e. the zones are
788 equal iff.: they have the same rdclass, origin, and nodes.
790 2003-07-17 Bob Halley <halley@dnspython.org>
792 * dns/message.py (Message.use_tsig): The method now allows for
793 greater control over the various fields in the generated signature
795 (_WireReader._get_section): UnknownTSIGKey is now raised if an
796 unknown key is encountered, or if a signed message has no keyring.
798 2003-07-16 Bob Halley <halley@dnspython.org>
800 * dns/tokenizer.py (Tokenizer._get_char): get_char and unget_char
801 have been renamed to _get_char and _unget_char since they are not
802 useful to clients of the tokenizer.
804 2003-07-15 Bob Halley <halley@dnspython.org>
806 * dns/zone.py (_MasterReader._rr_line): owner names were being
807 unconditionally relativized; it makes much more sense for them
808 to be relativized according to the relativization setting of
811 2003-07-12 Bob Halley <halley@dnspython.org>
813 * dns/resolver.py (Resolver.read_resolv_conf): The resolv.conf
814 parser did not allow blank / whitespace-only lines, nor did it
815 allow comments. Both are now supported.
817 2003-07-11 Bob Halley <halley@dnspython.org>
819 * dns/name.py (Name.to_digestable): to_digestable() now
820 requires an origin to be specified if the name is relative.
821 It will raise NeedAbsoluteNameOrOrigin if the name is
822 relative and there is either no origin or the origin is
824 (Name.split): returned the wrong answer if depth was 0 or depth
825 was the length of the name. split() now does bounds checking
826 on depth, and raises ValueError if depth < 0 or depth > the length
829 2003-07-10 Bob Halley <halley@dnspython.org>
831 * dns/ipv6.py (inet_ntoa): The routine now minimizes its output
832 strings. E.g. the IPv6 address
833 "0000:0000:0000:0000:0000:0000:0000:0001" is minimized to "::1".
834 We do not, however, make any effort to display embedded IPv4
835 addresses in the dot-quad notation.
837 2003-07-09 Bob Halley <halley@dnspython.org>
839 * dns/inet.py: We now supply our own AF_INET and AF_INET6
840 constants since AF_INET6 may not always be available. If the
841 socket module has AF_INET6, we will use it. If not, we will
842 use our own value for the constant.
844 * dns/query.py: the functions now take an optional af argument
845 specifying the address family to use when creating the socket.
847 * dns/rdatatype.py (is_metatype): a typo caused the function
848 return true only for type OPT.
850 * dns/message.py: message section list elements are now RRsets
851 instead of Nodes. This API change makes processing messages
852 easier for many applications.
854 2003-07-07 Bob Halley <halley@dnspython.org>
856 * dns/rrset.py: added. An RRset is a named rdataset.
858 * dns/rdataset.py (Rdataset.__eq__): rdatasets may now be compared
859 for equality and inequality with other objects. Rdataset instance
860 variables are now slotted.
862 * dns/message.py: The wire format and text format readers are now
863 classes. Variables related to reader state have been moved out
864 of the message class.
866 2003-07-06 Bob Halley <halley@dnspython.org>
868 * dns/name.py (from_text): '@' was not interpreted as the empty
871 * dns/zone.py: the master file reader derelativized names in rdata
872 relative to the zone's origin, not relative to the current origin.
873 The reader now deals with relativization in two steps. The rdata
874 is read and derelativized using the current origin. The rdata's
875 relativity is then chosen using the zone origin and the relativize
876 boolean. Here's an example.
882 If the zone origin is example., and relativization is on, then
883 This fragment will become:
885 bar.foo.example. 300 IN MX 0 blaz.foo.example.
887 after the first step (derelativization to current origin), and
889 bar.foo 300 IN MX 0 blaz.foo
891 after the second step (relativiation to zone origin).
893 * dns/namedict.py: added.
895 * dns/zone.py: The master file reader has been made into its
896 own class. Reader-related instance variables have been moved
897 form the zone class into the reader class.
899 * dns/zone.py: Add node_factory class attribute. An application
900 can now subclass Zone and Node and have a zone whose nodes are of
901 the subclassed Node type. The from_text(), from_file(), and
902 from_xfr() algorithms now take an optional zone_factory argument.
903 This allows the algorithms to be used to create zones whose class
904 is a subclass of Zone.
907 2003-07-04 Bob Halley <halley@dnspython.org>
909 * dns/renderer.py: added new wire format rendering module and
910 converted message.py to use it. Applications which want
911 fine-grained control over the conversion to wire format may call
912 the renderer directy, instead of having it called on their behalf
915 2003-07-02 Bob Halley <halley@dnspython.org>
917 * dns/name.py (_validate_labels): The NameTooLong test was
920 * dns/message.py (Message.to_wire): dns.exception.TooBig is
921 now raised if the wire encoding exceeds the specified
924 2003-07-01 Bob Halley <halley@dnspython.org>
926 * dns/message.py: EDNS encoding was broken. from_text()
927 didn't parse rcodes, flags, or eflags correctly. Comparing
928 messages with other types of objects didn't work.
930 2003-06-30 Bob Halley <halley@dnspython.org>
932 * (Version 1.0.0 released)
934 2003-06-30 Bob Halley <halley@dnspython.org>
936 * dns/rdata.py: Rdatas now implement rich comparisons instead of
939 * dns/name.py: Names now implement rich comparisons instead of
942 * dns/inet.py (inet_ntop): Always use our code, since the code
943 in the socket module doesn't support AF_INET6 conversions if
944 IPv6 sockets are not available on the system.
946 * dns/resolver.py (Answer.__init__): A dangling CNAME chain was
947 not raising NoAnswer.
949 * Added a simple resolver Cache class.
951 * Added an expiration attribute to answer instances.
953 2003-06-24 Bob Halley <halley@dnspython.org>
955 * (Version 1.0.0b3 released)
957 2003-06-24 Bob Halley <halley@dnspython.org>
959 * Renamed module "DNS" to "dns" to avoid conflicting with
962 2003-06-23 Bob Halley <halley@dnspython.org>
964 * The from_text() relativization controls now work the same way as
965 the to_text() controls.
967 * DNS/rdata.py: The parsing of generic rdata was broken.
969 2003-06-21 Bob Halley <halley@dnspython.org>
971 * (Version 1.0.0b2 released)
973 2003-06-21 Bob Halley <halley@dnspython.org>
975 * The Python 2.2 socket.inet_aton() doesn't seem to like
976 '255.255.255.255'. We work around this.
978 * Fixed bugs in rdata to_wire() and from_wire() routines of a few
979 types. These bugs were discovered by running the tests/zone.py
982 * Added implementation of type APL.
984 2003-06-20 Bob Halley <halley@dnspython.org>
986 * DNS/rdtypes/IN/AAAA.py: Use our own versions of inet_ntop and
987 inet_pton if the socket module doesn't provide them for us.
989 * The resolver now does a better job handling exceptions. In
990 particular, it no longer eats all exceptions; rather it handles
991 those exceptions it understands, and leaves the rest uncaught.
993 * Exceptions have been pulled into their own module. Almost all
994 exceptions raised by the code are now subclasses of
995 DNS.exception.DNSException. All form errors are subclasses of
996 DNS.exception.FormError (which is itself a subclass of
997 DNS.exception.DNSException).
999 2003-06-19 Bob Halley <halley@dnspython.org>
1001 * Added implementations of types DS, NXT, SIG, and WKS.
1003 * __cmp__ for type A and AAAA could produce incorrect results.
1005 2003-06-18 Bob Halley <halley@dnspython.org>
1007 * Started test suites for zone.py and tokenizer.py.
1009 * Added implementation of type KEY.
1011 * DNS/rdata.py(_base64ify): \n could be emitted erroneously.
1013 * DNS/rdtypes/ANY/SOA.py (SOA.from_text): The SOA RNAME field could
1014 be set to the value of MNAME in common cases.
1016 * DNS/rdtypes/ANY/X25.py: __init__ was broken.
1018 * DNS/zone.py (from_text): $TTL handling erroneously caused the
1019 next line to be eaten.
1021 * DNS/tokenizer.py (Tokenizer.get): parsing was broken for empty
1022 quoted strings. Quoted strings didn't handle \ddd escapes. Such
1023 escapes are appear not to comply with RFC 1035, but BIND allows
1024 them and they seem useful, so we allow them too.
1026 * DNS/rdtypes/ANY/ISDN.py (ISDN.from_text): parsing was
1027 broken for ISDN RRs without subaddresses.
1029 * DNS/zone.py (from_file): from_file() didn't work because
1030 some required parameters were not passed to from_text().
1032 2003-06-17 Bob Halley <halley@dnspython.org>
1034 * (Version 1.0.0b1 released)
1036 2003-06-17 Bob Halley <halley@dnspython.org>
1038 * Added implementation of type PX.
1040 2003-06-16 Bob Halley <halley@dnspython.org>
1042 * Added implementation of types CERT, GPOS, LOC, NSAP, NSAP-PTR.
1044 * DNS/rdatatype.py (_by_value): A cut-and-paste error had broken
1047 2003-06-12 Bob Halley <halley@dnspython.org>
1049 * Created a tests directory and started adding tests.
1051 * Added "and its documentation" to the permission grant in the
1054 2003-06-12 Bob Halley <halley@dnspython.org>
1056 * DNS/name.py (Name.is_wild): is_wild() erroneously raised IndexError
1057 if the name was empty.
1059 2003-06-10 Bob Halley <halley@dnspython.org>
1061 * Added implementations of types AFSDB, X25, and ISDN.
1063 * The documentation associated with the various rdata types has been
1064 improved. In particular, instance variables are now described.
1066 2003-06-09 Bob Halley <halley@dnspython.org>
1068 * Added implementations of types HINFO, RP, and RT.
1070 * DNS/message.py (make_query): Document that make_query() sets
1071 flags to DNS.flags.RD, and chooses a random query id.
1073 2003-06-05 Bob Halley <halley@dnspython.org>
1075 * (Version 1.0.0a2 released)
1077 2003-06-05 Bob Halley <halley@dnspython.org>
1079 * DNS/node.py: removed __getitem__ and __setitem__, since
1080 they are not used by the codebase and were not useful in
1083 * DNS/message.py (from_file): from_file() now allows a
1084 filename to be specified instead of a file object.
1086 * DNS/rdataset.py: The is_compatible() method of the
1087 DNS.rdataset.Rdataset class was deleted.
1089 2003-06-04 Bob Halley <halley@dnspython.org>
1091 * DNS/name.py (class Name): Names are now immutable.
1093 * DNS/name.py: the is_comparable() method has been removed, since
1094 names are always comparable.
1096 * DNS/resolver.py (Resolver.query): A query could run for up
1097 to the lifetime + the timeout. This has been corrected and the
1098 query will now only run up to the lifetime.
1100 2003-06-03 Bob Halley <halley@dnspython.org>
1102 * DNS/resolver.py: removed the 'new' function since it is not the
1103 style of the library to have such a function. Call
1104 DNS.resolver.Resolver() to make a new resolver.
1106 2003-06-03 Bob Halley <halley@dnspython.org>
1108 * DNS/resolver.py (Resolver._config_win32_fromkey): The DhcpServer
1109 list is space separated, not comma separated.
1111 2003-06-03 Bob Halley <halley@dnspython.org>
1113 * DNS/update.py: Added an update module to make generating updates
1116 2003-06-03 Bob Halley <halley@dnspython.org>
1118 * Commas were missing in some of the __all__ entries in various
1121 2003-05-30 Bob Halley <halley@dnspython.org>
1123 * (Version 1.0.0a1 released)
