Subject:	Net::DNS ≥ 1.06_06 generates broken SOA RRs

That is, the parentheses around the RDATA values are missing: $ perl -Ilib -MNet::DNS -E 'say Net::DNS->VERSION;$soa=Net::DNS::RR->new("@ARGV");say$soa->rdatastr' 'name SOA mname rname 0 14400 3600 1814400 3600' 1.0606 mname. rname. 0 ;serial 14400 ;refresh 3600 ;retry 1814400 ;expire 3600 ;minimum In older versions they were OK: $ perl -Ilib -MNet::DNS -E 'say Net::DNS->VERSION;$soa=Net::DNS::RR->new("@ARGV");say$soa->rdatastr' 'name SOA mname rname 0 14400 3600 1814400 3600' 1.06 ( mname. rname. 0 ;serial 14400 ;refresh 3600 ;retry 1814400 ;expire 3600 ;minimum ) The functionality was probably broken by the following commit: commit 24621a508c1ac518e1a518b3be4ecff80a6be89c Author: willem <willem@a29f3fcb-687d-e111-8194-001676cd6a66> Date: Tue Jun 7 09:04:50 2016 +0000 Generic method for annotating formatted rdata with comments git-svn-id: https://www.net-dns.org/svn/net-dns/trunk@1488 a29f3fcb-687d-e111-8194-001676cd6a66

Arguably, it is the older versions that are broken. RFC1035 requires that line terminations are to be ignored within parentheses in RR entries in master files. What it does *not* say, nor does it imply, that the parentheses form part of the RDATA. The parentheses are syntactically necessary to aggregate the lines of each individual RR within a master file into a single parsable entity. The string produced by $rr->rdstring() [aka rdatastr] always contains the entire RDATA, therefore the question of aggregation never arises. Neither can I think of any sensible use-case which would involve parsing the result from rdstring().
