- Implement a reference counter to ensure that newly entered records are not
|
|
purged immediately (really needed?)
|
|
- Perhaps do a two-step form of recursive query: first query those servers we
|
|
have got cached, then (if unsuccessful) look the others up and query again.
|
|
The impact of this optimisation may not be very big, because all sane servers
|
|
give A records for NS records if possible.
|
|
- Test for compatibility on other Unix-like Systems other than the BSDs and
|
|
Linux; rewrite the functions in netdev.c and icmp.c for those OSs if
|
|
necessary. Also try to get compatibility for other compilers than gcc.
|
|
- Write an install rule for the Slackware start-up script.
|
|
- Update the FAQ.
|
|
- Implement DNSSEC support. Since version 1.2.9, pdnsd is able to cache the RR
|
|
types necessary for DNSSEC, but the resolver is not yet security aware.
|
|
- Implement a lookup table (hash table) for queries in progress. This would
|
|
enable a thread that is resolving a query that is already being handled by
|
|
another thread to wait for that other thread to finish and copy its result
|
|
rather than independently query remote servers. It is very common for
|
|
resolvers to resend UDP queries if they don't get a reply within a timeout
|
|
period and if the answer is not yet cached, this will result in multiple
|
|
threads duplicating each others work in the current implementation.
