2014-09-01 Bob Halley * (Version 1.12.0 released) 2014-08-31 Bob Halley * The test system can now run the tests without requiring dnspython to be installed. * 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 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. * 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. * 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 * 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 * 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 * 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. 2014-01-10 Bob Halley * dns/inet.py (is_multicast): Removed lingering ord()s. 2013-12-11 Bob Halley * 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 * (Version 1.11.1 released) 2013-09-01 Bob Halley * 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 * 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. 2013-08-13 Bob Halley * APL RR trailing zero suppression didn't work due to insufficient python 3 porting. 2013-08-09 Bob Halley * 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 * 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 * 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 * (Version 1.11.0 released) 2013-04-28 Bob Halley * 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 * 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 * 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) 2012-12-31 Bob Halley * Pull up fix _winreg renamed to winreg in python 3 (thanks Christopher Lambacher) 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 * 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. 2012-04-10 Bob Halley * dns/dnssec.py (_validate_rrsig): Fix python3 port issues with RSA validation. 2012-04-08 Bob Halley * (Version 1.10.0 released) 2012-04-08 Bob Halley * 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 * 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 * 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 * 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 * 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 * 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 * (Version 1.9.4 released) 2011-03-24 Bob Halley * 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 * (Version 1.9.3 released) 2011-03-22 Bob Halley * 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 * 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 * 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 * dns/resolver.py (Resolver.query): disallow metaqueries. * dns/rdata.py (Rdata.__hash__): Added a __hash__ method for rdata. 2010-11-23 Bob Halley * (Version 1.9.2 released) 2010-11-23 Bob Halley * 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 * (Version 1.9.1 released) 2010-11-22 Bob Halley * 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 * (Version 1.9.0 released) 2010-11-07 Bob Halley * 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 * 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 * 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 * 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 * 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 * 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 * (Version 1.8.0 released) 2010-01-13 Bob Halley * dns/dnssec.py: Added RSASHA256 and RSASHA512 codepoints; added other missing codepoints to _algorithm_by_text. 2010-01-12 Bob Halley * 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 * 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 * 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 * 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 * 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 * 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 * (Version 1.7.1 released) 2009-06-19 Bob Halley * DLV.py was omitted from the kit * Negative prerequisites were not handled correctly in _get_section(). 2009-06-19 Bob Halley * (Version 1.7.0 released) 2009-06-19 Bob Halley * 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 * 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 * 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 * dns/query.py (xfr): Allow UDP IXFRs. Use "one_rr_per_rrset" mode when doing IXFR. 2009-03-30 Bob Halley * 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 * Added EDNS option support. 2008-10-16 Bob Halley * 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 * Add entropy module. * When validating TSIGs, we need to use the absolute name. 2008-06-03 Bob Halley * 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 * 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 * (Version 1.6.0 released) 2007-11-25 Bob Halley * dns/query.py (_wait_for): if select() raises an exception due to EINTR, we should just select() again. 2007-06-13 Bob Halley * 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 * dns/rdtypes/IN/NAPTR.py: NAPTR comparisons didn't compare the preference field due to a typo. 2007-02-07 Bob Halley * 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 * (Version 1.5.0 released) 2006-11-03 Bob Halley * dns/rdtypes/IN/DHCID.py: Added support for the DHCID RR type. 2006-11-02 Bob Halley * dns/query.py (udp): Messages from unexpected sources can now be ignored by setting ignore_unexpected to True. 2006-10-31 Bob Halley * dns/query.py (udp): When raising UnexpectedSource, add more detail about what went wrong to the exception. 2006-09-22 Bob Halley * 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 * 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 * 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 * 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 * dns/query.py (xfr): Add IXFR support. 2006-06-22 Bob Halley * dns/rdtypes/IN/IPSECKEY.py: Added support for the IPSECKEY RR type. 2006-06-21 Bob Halley * dns/rdtypes/ANY/SPF.py: Added support for the SPF RR type. 2006-06-02 Bob Halley * (Version 1.4.0 released) 2006-04-25 Bob Halley * dns/rrset.py (RRset.to_rdataset): Added a convenience method to convert an rrset into an rdataset. 2006-03-27 Bob Halley * 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 * dns/resolver.py (Resolver.query): The resolver deleted from a list while iterating it, which makes the iterator unhappy. 2006-03-17 Bob Halley * dns/resolver.py (Resolver.query): The resolver needlessly delayed responses for successful queries. 2006-01-18 Bob Halley * 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 * 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 * 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 * 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 * 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 * 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 * 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 * (Version 1.3.5 released) 2005-10-12 Bob Halley * 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 * dns/name.py: Added the parent() method, which returns the parent of a name. 2005-10-01 Bob Halley * 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 * dns/resolver.py (Resolver._compute_timeout): If time goes backwards a little bit, ignore it. 2005-07-31 Bob Halley * (Version 1.3.4 released) 2005-07-31 Bob Halley * 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 * dns/query.py: The requirement that the "where" parameter be an IPv4 or IPv6 address is now documented. 2005-06-04 Bob Halley * 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 * (Version 1.3.3 released) 2004-10-25 Bob Halley * 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 * 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 * 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 * 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 * 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 * (Version 1.3.2 released) 2004-08-04 Bob Halley * 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 * 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 * 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 * (Version 1.3.1 released) 2004-05-22 Bob Halley * 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 * 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 * 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 * 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 * (Version 1.3.0 released) 2004-03-19 Bob Halley * Added support for new DNSSEC types RRSIG, NSEC, and DNSKEY. 2004-01-16 Bob Halley * dns/query.py (_connect): Windows returns EWOULDBLOCK instead of EINPROGRESS when trying to connect a nonblocking socket. 2003-11-13 Bob Halley * 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 * 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 * (Version 1.2.0 released) 2003-11-03 Bob Halley * dns/zone.py (_MasterReader.read): The saved_state now includes the default TTL. 2003-11-01 Bob Halley * dns/tokenizer.py (Tokenizer.get): The tokenizer didn't handle escaped delimiters. 2003-10-27 Bob Halley * 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 * 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 * (Version 1.2.0b1 released) 2003-09-05 Bob Halley * 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 * dns/zone.py: dns.exception.SyntaxError is raised for unknown master file directives. 2003-08-28 Bob Halley * 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 * dns/zone.py: The _MasterReader now understands $INCLUDE. 2003-08-12 Bob Halley * 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 * (Version 1.1.0 released) 2003-08-07 Bob Halley * 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 * 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 * Node and all rdata types have been "slotted". This speeds things up a little and reduces memory usage noticeably. 2003-08-02 Bob Halley * (Version 1.1.0c1 released) 2003-08-02 Bob Halley * 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 * 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 * 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 * (Version 1.1.0b2 released) 2003-07-30 Bob Halley * 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 * dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses. 2003-07-19 Bob Halley * (Version 1.1.0b1 released) 2003-07-18 Bob Halley * 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 * 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 * 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 * 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 * dns/resolver.py (Resolver.read_resolv_conf): The resolv.conf parser did not allow blank / whitespace-only lines, nor did it allow comments. Both are now supported. 2003-07-11 Bob Halley * dns/name.py (Name.to_digestable): to_digestable() now requires an origin to be specified if the name is relative. It will raise NeedAbsoluteNameOrOrigin if the name is relative and there is either no origin or the origin is itself relative. (Name.split): returned the wrong answer if depth was 0 or depth was the length of the name. split() now does bounds checking on depth, and raises ValueError if depth < 0 or depth > the length of the name. 2003-07-10 Bob Halley * dns/ipv6.py (inet_ntoa): The routine now minimizes its output strings. E.g. the IPv6 address "0000:0000:0000:0000:0000:0000:0000:0001" is minimized to "::1". We do not, however, make any effort to display embedded IPv4 addresses in the dot-quad notation. 2003-07-09 Bob Halley * dns/inet.py: We now supply our own AF_INET and AF_INET6 constants since AF_INET6 may not always be available. If the socket module has AF_INET6, we will use it. If not, we will use our own value for the constant. * dns/query.py: the functions now take an optional af argument specifying the address family to use when creating the socket. * dns/rdatatype.py (is_metatype): a typo caused the function return true only for type OPT. * dns/message.py: message section list elements are now RRsets instead of Nodes. This API change makes processing messages easier for many applications. 2003-07-07 Bob Halley * dns/rrset.py: added. An RRset is a named rdataset. * dns/rdataset.py (Rdataset.__eq__): rdatasets may now be compared for equality and inequality with other objects. Rdataset instance variables are now slotted. * dns/message.py: The wire format and text format readers are now classes. Variables related to reader state have been moved out of the message class. 2003-07-06 Bob Halley * dns/name.py (from_text): '@' was not interpreted as the empty name. * dns/zone.py: the master file reader derelativized names in rdata relative to the zone's origin, not relative to the current origin. The reader now deals with relativization in two steps. The rdata is read and derelativized using the current origin. The rdata's relativity is then chosen using the zone origin and the relativize boolean. Here's an example. $ORIGIN foo.example. $TTL 300 bar MX 0 blaz If the zone origin is example., and relativization is on, then This fragment will become: bar.foo.example. 300 IN MX 0 blaz.foo.example. after the first step (derelativization to current origin), and bar.foo 300 IN MX 0 blaz.foo after the second step (relativiation to zone origin). * dns/namedict.py: added. * dns/zone.py: The master file reader has been made into its own class. Reader-related instance variables have been moved form the zone class into the reader class. * dns/zone.py: Add node_factory class attribute. An application can now subclass Zone and Node and have a zone whose nodes are of the subclassed Node type. The from_text(), from_file(), and from_xfr() algorithms now take an optional zone_factory argument. This allows the algorithms to be used to create zones whose class is a subclass of Zone. 2003-07-04 Bob Halley * dns/renderer.py: added new wire format rendering module and converted message.py to use it. Applications which want fine-grained control over the conversion to wire format may call the renderer directy, instead of having it called on their behalf by the message code. 2003-07-02 Bob Halley * dns/name.py (_validate_labels): The NameTooLong test was incorrect. * dns/message.py (Message.to_wire): dns.exception.TooBig is now raised if the wire encoding exceeds the specified maximum size. 2003-07-01 Bob Halley * dns/message.py: EDNS encoding was broken. from_text() didn't parse rcodes, flags, or eflags correctly. Comparing messages with other types of objects didn't work. 2003-06-30 Bob Halley * (Version 1.0.0 released) 2003-06-30 Bob Halley * dns/rdata.py: Rdatas now implement rich comparisons instead of __cmp__. * dns/name.py: Names now implement rich comparisons instead of __cmp__. * dns/inet.py (inet_ntop): Always use our code, since the code in the socket module doesn't support AF_INET6 conversions if IPv6 sockets are not available on the system. * dns/resolver.py (Answer.__init__): A dangling CNAME chain was not raising NoAnswer. * Added a simple resolver Cache class. * Added an expiration attribute to answer instances. 2003-06-24 Bob Halley * (Version 1.0.0b3 released) 2003-06-24 Bob Halley * Renamed module "DNS" to "dns" to avoid conflicting with PyDNS. 2003-06-23 Bob Halley * The from_text() relativization controls now work the same way as the to_text() controls. * DNS/rdata.py: The parsing of generic rdata was broken. 2003-06-21 Bob Halley * (Version 1.0.0b2 released) 2003-06-21 Bob Halley * The Python 2.2 socket.inet_aton() doesn't seem to like '255.255.255.255'. We work around this. * Fixed bugs in rdata to_wire() and from_wire() routines of a few types. These bugs were discovered by running the tests/zone.py Torture1 test. * Added implementation of type APL. 2003-06-20 Bob Halley * DNS/rdtypes/IN/AAAA.py: Use our own versions of inet_ntop and inet_pton if the socket module doesn't provide them for us. * The resolver now does a better job handling exceptions. In particular, it no longer eats all exceptions; rather it handles those exceptions it understands, and leaves the rest uncaught. * Exceptions have been pulled into their own module. Almost all exceptions raised by the code are now subclasses of DNS.exception.DNSException. All form errors are subclasses of DNS.exception.FormError (which is itself a subclass of DNS.exception.DNSException). 2003-06-19 Bob Halley * Added implementations of types DS, NXT, SIG, and WKS. * __cmp__ for type A and AAAA could produce incorrect results. 2003-06-18 Bob Halley * Started test suites for zone.py and tokenizer.py. * Added implementation of type KEY. * DNS/rdata.py(_base64ify): \n could be emitted erroneously. * DNS/rdtypes/ANY/SOA.py (SOA.from_text): The SOA RNAME field could be set to the value of MNAME in common cases. * DNS/rdtypes/ANY/X25.py: __init__ was broken. * DNS/zone.py (from_text): $TTL handling erroneously caused the next line to be eaten. * DNS/tokenizer.py (Tokenizer.get): parsing was broken for empty quoted strings. Quoted strings didn't handle \ddd escapes. Such escapes are appear not to comply with RFC 1035, but BIND allows them and they seem useful, so we allow them too. * DNS/rdtypes/ANY/ISDN.py (ISDN.from_text): parsing was broken for ISDN RRs without subaddresses. * DNS/zone.py (from_file): from_file() didn't work because some required parameters were not passed to from_text(). 2003-06-17 Bob Halley * (Version 1.0.0b1 released) 2003-06-17 Bob Halley * Added implementation of type PX. 2003-06-16 Bob Halley * Added implementation of types CERT, GPOS, LOC, NSAP, NSAP-PTR. * DNS/rdatatype.py (_by_value): A cut-and-paste error had broken NSAP and NSAP-PTR. 2003-06-12 Bob Halley * Created a tests directory and started adding tests. * Added "and its documentation" to the permission grant in the license. 2003-06-12 Bob Halley * DNS/name.py (Name.is_wild): is_wild() erroneously raised IndexError if the name was empty. 2003-06-10 Bob Halley * Added implementations of types AFSDB, X25, and ISDN. * The documentation associated with the various rdata types has been improved. In particular, instance variables are now described. 2003-06-09 Bob Halley * Added implementations of types HINFO, RP, and RT. * DNS/message.py (make_query): Document that make_query() sets flags to DNS.flags.RD, and chooses a random query id. 2003-06-05 Bob Halley * (Version 1.0.0a2 released) 2003-06-05 Bob Halley * DNS/node.py: removed __getitem__ and __setitem__, since they are not used by the codebase and were not useful in general either. * DNS/message.py (from_file): from_file() now allows a filename to be specified instead of a file object. * DNS/rdataset.py: The is_compatible() method of the DNS.rdataset.Rdataset class was deleted. 2003-06-04 Bob Halley * DNS/name.py (class Name): Names are now immutable. * DNS/name.py: the is_comparable() method has been removed, since names are always comparable. * DNS/resolver.py (Resolver.query): A query could run for up to the lifetime + the timeout. This has been corrected and the query will now only run up to the lifetime. 2003-06-03 Bob Halley * DNS/resolver.py: removed the 'new' function since it is not the style of the library to have such a function. Call DNS.resolver.Resolver() to make a new resolver. 2003-06-03 Bob Halley * DNS/resolver.py (Resolver._config_win32_fromkey): The DhcpServer list is space separated, not comma separated. 2003-06-03 Bob Halley * DNS/update.py: Added an update module to make generating updates easier. 2003-06-03 Bob Halley * Commas were missing in some of the __all__ entries in various __init__.py files. 2003-05-30 Bob Halley * (Version 1.0.0a1 released)
