To Do list for Net::DNS
=======================
* Work on Resolver.pm:
- Add a method to set the query source port.
- Add an optional argument to Net::DNS::Resolver->new to read a
specific configuration file instead of using the default files.
- Accept options in resolver config files.
- Show more info about the query when $res->debug(1).
- Work on a way to use the same socket for background queries.
- Write $res->axfr_start, $res->axfr_next.
- Document $res->errorstring messages.
- Work on efficiency of IO::Socket handling.
- Implement AAONLY queries. Here's a code fragment to set the
nameserver list to the hosts returned in the authority section:
$res->nameservers(map { $_->nsdname }
grep { $_->type eq "NS" }
$ans->authority);
* Work on the manual pages:
- Review the examples in the Net::DNS manual page.
- Make "->" non-breaking.
- Reorganize to put the most frequently-used methods first. Suggested
by John Line.
- Add manual pages for individual RR types to the homepage.
* Consider using function prototypes.
* Get rid of .* in AAAA.pm; write more tests for AAAA.pm.
* Allow Net::DNS::RR::LOC->latlon to set the lat/lon.
* Work on the dynamic update code. Some things remaining to do:
- Append the default zone in update packets if the name doesn't
contain a dot.
- Add the "new_from_string" method to the following RR types:
EID
NIMLOC
NSAP
NULL
- Do sanity checking on user-created RR objects. Update the BUGS
section in RR.pm when this is complete.
- Allow yxrrset & friends to take an RR object as an argument.
- Do more sanity checking on yxrrset & friends.
- Add an "update" method to the resolver class to send the update
packet to the zone's authoritative nameservers (see also RFC
2136, Section 4).
- Do case-insensitive comparisons in Net::DNS::Packet->dn_comp.
* Consider getting rid of the "; no data" string from $rr->rdatastr. Add
it possibly in $rr->string.
* Improve the error handling and reporting. Some things to do:
- Get rid of Carp::confess as many places as possible.
- Make sure empty RDATA sections don't cause the program to print
the obnoxious "no such method" warning.
- Check for invalid RR types or classes.
- Handle "host is down" error in Resolver.pm.
- Set a more descriptive error if a zone transfer fails, especially
if the nameserver isn't authoritative (current code returns NOERROR
if the nameserver answered but wasn't authoritative).
- Consider documenting the use of "eval" to avoid a fatal error
in certain places. Idea by Dirk Herr-Hoyman.
* Restructure some of the code. Some things to look at:
- Net::DNS::Resolver->send (needs to be broken into smaller pieces).
- Net::DNS::Packet->dn_expand (get rid of the recursive call).
- Passing of references between Net::DNS::Packet and Net::DNS::RR.
* Add more RR types. Currently unimplemented are:
MD RFC 1035 (obsolete)
MF RFC 1035 (obsolete)
WKS RFC 1035
NSAP_PTR RFC 1348 (deprecated)
GPOS RFC 1712 (withdrawn)
KEY RFC 2065
NXT RFC 2065
SIG RFC 2065
ATMA ???
TSIG draft-ietf-dnsind-tsig-xx.txt
* Fix the TXT RR to handle more than 1 string in the RDATA section
(RFC 1035, Section 3.3.14).
* Check the EID, NIMLOC, and NULL RR handling.
* Add test cases for NULL, EID, and NIMLOC to private zone data.
NULL isn't allowed in master files per RFC 1035, Section 3.3.10;
BIND 8.1-REL doesn't appear to implement EID or NIMLOC (perhaps
via dynamic update?).
* Write some front-end methods to do CNAME translations automagically.
* Work on demo scripts:
- Add a copyright notice to the demo scripts.
- Work on demo/axfr:
* Add a print statement to tell whether the zone info comes from
a file or a zone transfer.
- Work on demo/srv (not included with the distribution). Remaining
to do:
* Documentation. Don't forget to add a reference to it in the other
demo scripts.
* Consider adding "sub srv" to DNS.pm.
* Add to the Changes file.
- Work on nsupdate.pl (not included with the distribution) and add it
to the demo directory. Remaining to do:
* Write documentation.
* Make it more robust.
- Work on dns.cgi (not included with the distribution) and add it to
the demo directory. Some things remaining to do:
* Check for HTTP_USER_AGENT in zone transfers.
* Add a way to change resolver settings. Edit do_axfr and remove
the query for the zone's nameservers when this is finished.
* Add support for dynamic updates.
- Consider writing a simple nameserver with Net::DNS.
* Do more study of resolver behavior as recommended in RFCs 1035, 1123,
and 2136.
* Add some text- and html-specific sections to the manual pages.
* Check code for conformance to the guidelines listed in The Perl 5 Module
List. Check style & efficiency according to the perlstyle manpage and
the Camel.
* Consider providing an .xs file for those who wish to link against
libresolv or libbind instead of using the entirely-Perl resolver.
* Consider rewriting the packet-parsing code in C for increased speed,
or possibly going back to using Dave Shield's resparse library.
