[Pdns-users] Wildcards not behaving the same in v3.x

[Billy]

I'm trying to make the transition from v2.9 to v3.x but am running into issues regarding wildcards.

Here's an example of the query logic being used for both versions:

mysql> select id,domain_id,name,type from records where name = 'testdomain.com';
+----------+-----------+-----------+------+
| id       | domain_id | name      | type |
+----------+-----------+-----------+------+
| 37216424 |   2119933 | testdomain.com | MX   |
| 37216397 |   2119933 | testdomain.com | NS   |
| 37216398 |   2119933 | testdomain.com | NS   |
| 52774643 |   2119933 | testdomain.com | SOA  |
| 47269400 |   2119933 | testdomain.com | TXT  |
+----------+-----------+-----------+------+
5 rows in set (0.00 sec)

v2.9:
Query    select content,ttl,prio,type,domain_id,name from records where name='testdomain.com'
Query    select content,ttl,prio,type,domain_id,name from records where type='SOA' and name='testdomain.com'
Query    select content,ttl,prio,type,domain_id,name from records where name='*.com'

v3.3:
Query     select content,ttl,prio,type,domain_id,name from records where type='SOA' and name='testdomain.com'
Query     select content,ttl,prio,type,domain_id,name from records where name='testdomain.com' and domain_id=2119933

In version 2.9, when I query for testdomain.com's A record, pdns checks it's zone, doesn't find an A rr or wildcard label and then moves up the tree and finds and returns the wildcard entry I have setup in the 'com' zone.

In version 3.x, pdns only checks what's in testdomain.com's zone, doesn't find the A rr or wildcard and returns with an empty response. I know this is related to rfc guidelines, but for now I need to retain the old behavior. I tried the pipe backend via a perl script, but the amount of dns traffic proved to be too great and severely affected performance.

Hoping someone here has faced a similar issue and can provide a solution.

Thanks,

Billy
