Thanks to Mark R. Levinson for the bug report, + regression test, and fix. + +2003-11-07 Bob Halley <halley@dnspython.org> + + * (Version 1.2.0 released) + +2003-11-03 Bob Halley <halley@dnspython.org> + + * dns/zone.py (_MasterReader.read): The saved_state now includes + the default TTL. + +2003-11-01 Bob Halley <halley@dnspython.org> + + * dns/tokenizer.py (Tokenizer.get): The tokenizer didn't + handle escaped delimiters. + +2003-10-27 Bob Halley <halley@dnspython.org> + + * dns/resolver.py (Resolver.read_resolv_conf): If no nameservers + are configured in /etc/resolv.conf, the default nameserver + list should be ['127.0.0.1']. + +2003-09-08 Bob Halley <halley@dnspython.org> + + * dns/resolver.py (Resolver._config_win32_fromkey): We didn't + catch WindowsError, which can happen if a key is not defined + in the registry. + +2003-09-06 Bob Halley <halley@dnspython.org> + + * (Version 1.2.0b1 released) + +2003-09-05 Bob Halley <halley@dnspython.org> + + * dns/query.py: Timeout support has been overhauled to provide + timeouts under Python 2.2 as well as 2.3, and to provide more + accurate expiration. + +2003-08-30 Bob Halley <halley@dnspython.org> + + * dns/zone.py: dns.exception.SyntaxError is raised for unknown + master file directives. + +2003-08-28 Bob Halley <halley@dnspython.org> + + * dns/zone.py: $INCLUDE processing is now enabled/disabled using + the allow_include parameter. The default is to process $INCLUDE + for from_file(), and to disallow $INCLUDE for from_text(). The + master reader now calls zone.check_origin_node() by default after + the zone has been read. find_rdataset() called get_node() instead + of find_node(), which result in an incorrect exception. The + relativization state of a zone is now remembered and applied + consistently when looking up names. from_xfr() now supports + relativization like the _MasterReader. + +2003-08-22 Bob Halley <halley@dnspython.org> + + * dns/zone.py: The _MasterReader now understands $INCLUDE. + +2003-08-12 Bob Halley <halley@dnspython.org> + + * dns/zone.py: The _MasterReader now specifies the file and line + number when a syntax error occurs. The BIND 8 TTL format is now + understood when loading a zone, though it will never be emitted. + The from_file() function didn't pass the zone_factory parameter + to from_text(). + +2003-08-10 Bob Halley <halley@dnspython.org> + + * (Version 1.1.0 released) + +2003-08-07 Bob Halley <halley@dnspython.org> + + * dns/update.py (Update._add): A typo meant that _add would + fail if the thing being added was an Rdata object (as + opposed to an Rdataset or the textual form of an Rdata). + +2003-08-05 Bob Halley <halley@dnspython.org> + + * dns/set.py: the simple Set class has been moved to its + own module, and augmented to support more set operations. + +2003-08-04 Bob Halley <halley@dnspython.org> + + * Node and all rdata types have been "slotted". This speeds + things up a little and reduces memory usage noticeably. + +2003-08-02 Bob Halley <halley@dnspython.org> + + * (Version 1.1.0c1 released) + +2003-08-02 Bob Halley <halley@dnspython.org> + + * dns/rdataset.py: SimpleSets now support more set options. + + * dns/message.py: Added the get_rrset() method. from_file() now + allows Unicode filenames and turns on universal newline support if + it opens the file itself. + + * dns/node.py: Added the delete_rdataset() and replace_rdataset() + methods. + + * dns/zone.py: Added the delete_node(), delete_rdataset(), and + replace_rdataset() methods. from_file() now allows Unicode + filenames and turns on universal newline support if it opens the + file itself. Added a to_file() method. + +2003-08-01 Bob Halley <halley@dnspython.org> + + * dns/opcode.py: Opcode from/to text converters now understand + numeric opcodes. The to_text() method will return a numeric opcode + string if it doesn't know a text name for the opcode. + + * dns/message.py: Added set_rcode(). Fixed code where ednsflags + wasn't treated as a long. + + * dns/rcode.py: ednsflags wasn't treated as a long. Rcode from/to + text converters now understand numeric rcodes. The to_text() + method will return a numeric rcode string if it doesn't know + a text name for the rcode. + + * examples/reverse.py: Added a new example program that builds a + reverse (address-to-name) mapping table from the name-to-address + mapping specified by A RRs in zone files. + + * dns/node.py: Added get_rdataset() method. + + * dns/zone.py: Added get_rdataset() and get_rrset() methods. Added + iterate_rdatas(). + +2003-07-31 Bob Halley <halley@dnspython.org> + + * dns/zone.py: Added the iterate_rdatasets() method which returns + a generator which yields (name, rdataset) tuples for all the + rdatasets in the zone matching the specified rdatatype. + +2003-07-30 Bob Halley <halley@dnspython.org> + + * (Version 1.1.0b2 released) + +2003-07-30 Bob Halley <halley@dnspython.org> + + * dns/zone.py: Added find_rrset() and find_rdataset() convenience + methods. They let you retrieve rdata with the specified name + and type in one call. + + * dns/node.py: Nodes no longer have names; owner names are + associated with nodes in the Zone object's nodes dictionary. + + * dns/zone.py: Zone objects now implement more of the standard + mapping interface. __iter__ has been changed to iterate the keys + rather than values to match the standard mapping interface's + behavior. + +2003-07-20 Bob Halley <halley@dnspython.org> + + * dns/ipv6.py (inet_ntoa): Handle embedded IPv4 addresses. + +2003-07-19 Bob Halley <halley@dnspython.org> + + * (Version 1.1.0b1 released) + +2003-07-18 Bob Halley <halley@dnspython.org> + + * dns/tsig.py: The TSIG validation of TCP streams where not + every message is signed now works correctly. + + * dns/zone.py: Zones can now be compared for equality and + inequality. If the other object in the comparison is also + a zone, then "the right thing" happens; i.e. the zones are + equal iff.: they have the same rdclass, origin, and nodes. + +2003-07-17 Bob Halley <halley@dnspython.org> + + * dns/message.py (Message.use_tsig): The method now allows for + greater control over the various fields in the generated signature + (e.g. fudge). + (_WireReader._get_section): UnknownTSIGKey is now raised if an + unknown key is encountered, or if a signed message has no keyring. + +2003-07-16 Bob Halley <halley@dnspython.org> + + * dns/tokenizer.py (Tokenizer._get_char): get_char and unget_char + have been renamed to _get_char and _unget_char since they are not + useful to clients of the tokenizer. + +2003-07-15 Bob Halley <halley@dnspython.org> + + * dns/zone.py (_MasterReader._rr_line): owner names were being + unconditionally relativized; it makes much more sense for them + to be relativized according to the relativization setting of + the reader. + +2003-07-12 Bob Halley <halley@dnspython.org> + + * dns/resolver.py (Resolver.read_resolv_conf): The resolv.conf + parser did not allow blank / whitespace-only lines, nor did it + allow comments. Both are now supported. + +2003-07-11 Bob Halley <halley@dnspython.org> + + * dns/name.py (Name.to_digestable): to_digestable() now + requires an origin to be specified if the name is relative. + It will raise NeedAbsoluteNameOrOrigin if the name is + relative and there is either no origin or the origin is + itself relative. + (Name.split): returned the wrong answer if depth was 0 or depth + was the length of the name. split() now does bounds checking + on depth, and raises ValueError if depth < 0 or depth > the length + of the name. + +2003-07-10 Bob Halley <halley@dnspython.org> + + * dns/ipv6.py (inet_ntoa): The routine now minimizes its output + strings. E.g. the IPv6 address + "0000:0000:0000:0000:0000:0000:0000:0001" is minimized to "::1". + We do not, however, make any effort to display embedded IPv4 + addresses in the dot-quad notation. + +2003-07-09 Bob Halley <halley@dnspython.org> + + * dns/inet.py: We now supply our own AF_INET and AF_INET6 + constants since AF_INET6 may not always be available. If the + socket module has AF_INET6, we will use it. If not, we will + use our own value for the constant. + + * dns/query.py: the functions now take an optional af argument + specifying the address family to use when creating the socket. + + * dns/rdatatype.py (is_metatype): a typo caused the function + return true only for type OPT. + + * dns/message.py: message section list elements are now RRsets + instead of Nodes. This API change makes processing messages + easier for many applications. + +2003-07-07 Bob Halley <halley@dnspython.org> + + * dns/rrset.py: added. An RRset is a named rdataset. + + * dns/rdataset.py (Rdataset.__eq__): rdatasets may now be compared + for equality and inequality with other objects. Rdataset instance + variables are now slotted. + + * dns/message.py: The wire format and text format readers are now + classes. Variables related to reader state have been moved out + of the message class. + +2003-07-06 Bob Halley <halley@dnspython.org> + + * dns/name.py (from_text): '@' was not interpreted as the empty + name. + + * dns/zone.py: the master file reader derelativized names in rdata + relative to the zone's origin, not relative to the current origin. + The reader now deals with relativization in two steps. The rdata + is read and derelativized using the current origin. The rdata's + relativity is then chosen using the zone origin and the relativize + boolean. Here's an example. + + $ORIGIN foo.example. + $TTL 300 + bar MX 0 blaz + + If the zone origin is example., and relativization is on, then + This fragment will become: + + bar.foo.example. 300 IN MX 0 blaz.foo.example. + + after the first step (derelativization to current origin), and + + bar.foo 300 IN MX 0 blaz.foo + + after the second step (relativiation to zone origin). + + * dns/namedict.py: added. + + * dns/zone.py: The master file reader has been made into its + own class. Reader-related instance variables have been moved + form the zone class into the reader class. + + * dns/zone.py: Add node_factory class attribute. An application + can now subclass Zone and Node and have a zone whose nodes are of + the subclassed Node type. The from_text(), from_file(), and + from_xfr() algorithms now take an optional zone_factory argument. + This allows the algorithms to be used to create zones whose class + is a subclass of Zone. + + +2003-07-04 Bob Halley <halley@dnspython.org> + + * dns/renderer.py: added new wire format rendering module and + converted message.py to use it. Applications which want + fine-grained control over the conversion to wire format may call + the renderer directy, instead of having it called on their behalf + by the message code. + +2003-07-02 Bob Halley <halley@dnspython.org> + + * dns/name.py (_validate_labels): The NameTooLong test was + incorrect. + + * dns/message.py (Message.to_wire): dns.exception.TooBig is + now raised if the wire encoding exceeds the specified + maximum size. + +2003-07-01 Bob Halley <halley@dnspython.org> + + * dns/message.py: EDNS encoding was broken. from_text() + didn't parse rcodes, flags, or eflags correctly. Comparing + messages with other types of objects didn't work. + +2003-06-30 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0 released) + +2003-06-30 Bob Halley <halley@dnspython.org> + + * dns/rdata.py: Rdatas now implement rich comparisons instead of + __cmp__. + + * dns/name.py: Names now implement rich comparisons instead of + __cmp__. + + * dns/inet.py (inet_ntop): Always use our code, since the code + in the socket module doesn't support AF_INET6 conversions if + IPv6 sockets are not available on the system. + + * dns/resolver.py (Answer.__init__): A dangling CNAME chain was + not raising NoAnswer. + + * Added a simple resolver Cache class. + + * Added an expiration attribute to answer instances. + +2003-06-24 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0b3 released) + +2003-06-24 Bob Halley <halley@dnspython.org> + + * Renamed module "DNS" to "dns" to avoid conflicting with + PyDNS. + +2003-06-23 Bob Halley <halley@dnspython.org> + + * The from_text() relativization controls now work the same way as + the to_text() controls. + + * DNS/rdata.py: The parsing of generic rdata was broken. + +2003-06-21 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0b2 released) + +2003-06-21 Bob Halley <halley@dnspython.org> + + * The Python 2.2 socket.inet_aton() doesn't seem to like + '255.255.255.255'. We work around this. + + * Fixed bugs in rdata to_wire() and from_wire() routines of a few + types. These bugs were discovered by running the tests/zone.py + Torture1 test. + + * Added implementation of type APL. + +2003-06-20 Bob Halley <halley@dnspython.org> + + * DNS/rdtypes/IN/AAAA.py: Use our own versions of inet_ntop and + inet_pton if the socket module doesn't provide them for us. + + * The resolver now does a better job handling exceptions. In + particular, it no longer eats all exceptions; rather it handles + those exceptions it understands, and leaves the rest uncaught. + + * Exceptions have been pulled into their own module. Almost all + exceptions raised by the code are now subclasses of + DNS.exception.DNSException. All form errors are subclasses of + DNS.exception.FormError (which is itself a subclass of + DNS.exception.DNSException). + +2003-06-19 Bob Halley <halley@dnspython.org> + + * Added implementations of types DS, NXT, SIG, and WKS. + + * __cmp__ for type A and AAAA could produce incorrect results. + +2003-06-18 Bob Halley <halley@dnspython.org> + + * Started test suites for zone.py and tokenizer.py. + + * Added implementation of type KEY. + + * DNS/rdata.py(_base64ify): \n could be emitted erroneously. + + * DNS/rdtypes/ANY/SOA.py (SOA.from_text): The SOA RNAME field could + be set to the value of MNAME in common cases. + + * DNS/rdtypes/ANY/X25.py: __init__ was broken. + + * DNS/zone.py (from_text): $TTL handling erroneously caused the + next line to be eaten. + + * DNS/tokenizer.py (Tokenizer.get): parsing was broken for empty + quoted strings. Quoted strings didn't handle \ddd escapes. Such + escapes are appear not to comply with RFC 1035, but BIND allows + them and they seem useful, so we allow them too. + + * DNS/rdtypes/ANY/ISDN.py (ISDN.from_text): parsing was + broken for ISDN RRs without subaddresses. + + * DNS/zone.py (from_file): from_file() didn't work because + some required parameters were not passed to from_text(). + +2003-06-17 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0b1 released) + +2003-06-17 Bob Halley <halley@dnspython.org> + + * Added implementation of type PX. + +2003-06-16 Bob Halley <halley@dnspython.org> + + * Added implementation of types CERT, GPOS, LOC, NSAP, NSAP-PTR. + + * DNS/rdatatype.py (_by_value): A cut-and-paste error had broken + NSAP and NSAP-PTR. + +2003-06-12 Bob Halley <halley@dnspython.org> + + * Created a tests directory and started adding tests. + + * Added "and its documentation" to the permission grant in the + license. + +2003-06-12 Bob Halley <halley@dnspython.org> + + * DNS/name.py (Name.is_wild): is_wild() erroneously raised IndexError + if the name was empty. + +2003-06-10 Bob Halley <halley@dnspython.org> + + * Added implementations of types AFSDB, X25, and ISDN. + + * The documentation associated with the various rdata types has been + improved. In particular, instance variables are now described. + +2003-06-09 Bob Halley <halley@dnspython.org> + + * Added implementations of types HINFO, RP, and RT. + + * DNS/message.py (make_query): Document that make_query() sets + flags to DNS.flags.RD, and chooses a random query id. + +2003-06-05 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0a2 released) + +2003-06-05 Bob Halley <halley@dnspython.org> + + * DNS/node.py: removed __getitem__ and __setitem__, since + they are not used by the codebase and were not useful in + general either. + + * DNS/message.py (from_file): from_file() now allows a + filename to be specified instead of a file object. + + * DNS/rdataset.py: The is_compatible() method of the + DNS.rdataset.Rdataset class was deleted. + +2003-06-04 Bob Halley <halley@dnspython.org> + + * DNS/name.py (class Name): Names are now immutable. + + * DNS/name.py: the is_comparable() method has been removed, since + names are always comparable. + + * DNS/resolver.py (Resolver.query): A query could run for up + to the lifetime + the timeout. This has been corrected and the + query will now only run up to the lifetime. + +2003-06-03 Bob Halley <halley@dnspython.org> + + * DNS/resolver.py: removed the 'new' function since it is not the + style of the library to have such a function. Call + DNS.resolver.Resolver() to make a new resolver. + +2003-06-03 Bob Halley <halley@dnspython.org> + + * DNS/resolver.py (Resolver._config_win32_fromkey): The DhcpServer + list is space separated, not comma separated. + +2003-06-03 Bob Halley <halley@dnspython.org> + + * DNS/update.py: Added an update module to make generating updates + easier. + +2003-06-03 Bob Halley <halley@dnspython.org> + + * Commas were missing in some of the __all__ entries in various + __init__.py files. + +2003-05-30 Bob Halley <halley@dnspython.org> + + * (Version 1.0.0a1 released) |
