Re: Core dumps

Así es como trabaja el driver mi amigo. Si su servidor de DNS es autoritario para la zona example.com y posee un registro de tipo A con dato 10.0.0.1:

dig a www.example.com --> se irán cortando porciones del nombre de dominio completo hasta llegar a una zona soportada por la BD de vuestro DNS.

SELECT zone FROM resource_records WHERE zone = 'www.example.com' --> Usted no posee una zona con este nombre, por tanto se retira "www" y se repite la consulta;
SELECT zone FROM resource_records WHERE zone = 'example.com' --> Usted sí posee una zona con este nombre, por tanto esta zona pasa a ser reemplazada en las restantes consultas por el token %zone% y www será reemplazado en las mismas restantes consultas por el token %record%.

Here is a new an interesting thing I just noticed.  I turned on mysql  
query logging to be able to see if any one query in particular was  
causing an issue.

I kept similar to this:
090508  3:09:34	     24 Query       SELECT zone FROM resource_records  
WHERE zone = 'www.a.com'
		     24 Query       SELECT zone FROM resource_records WHERE zone =  
'a.com'
		     24 Query       SELECT zone FROM resource_records WHERE zone =  
'com'

That is the result of one dig:
dig  www.a.com @ns1.example.com SOA

Why is it spitting it up and trying all three?

I can make some pretty cool looking logs with this, which can not be  
nice on the DB, let alone the fact that people could use this to beat  
the heck out of any DLZ db out there...

dig a.b.c.d.e.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z.com  
@ns1.example.com SOA

SELECT zone FROM resource_records
	WHERE zone = 'a.b.c.d.e.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z.com'
SELECT zone FROM resource_records
	WHERE zone = 'b.c.d.e.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z.com'
SELECT zone FROM resource_records WHERE zone =  
'c.d.e.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z.com'

Suggestions?
