Downgrade the dns_clientinfo_t structure to not contain dbversion
The DNS_CLIENTINFOMETHODS_VERSION
and _AGE
was bumped to 2 and 1 respectively, but the clientinfomethods->dbversion()
method is not used anywhere and instead clientinfo->dbversion()
method is the correct way of accessing the method.
There's also now way how to set the function, so it is always NULL.
We should also probably have a test that dlz_minimal.h
versions are always equal or lower than the clientinfo.h versions, but that could be solved in a separate ticket.
Closes #971 (closed)
