Bug #86859 for Net-DNS-ZoneFile-Fast: on_error handler broken when file is not accessible

First of all, thank you very much for this fine module which was already very useful to me in several projects! There is only one small annoyance regarding the on_error handler: Since it is initialized not until after trying to open the zone file, it does not work when opening the file fails. E.g. … $ perl -MNet::DNS::ZoneFile::Fast -E Net::DNS::ZoneFile::Fast::parse( file => shift, on_error => sub { say "on_error called: @_" }, soft_errors => 1, zone => "example.org" ); say "OK"' /etc/passwd on_error called: 1 syntax error OK … works as expected, but … $ perl -MNet::DNS::ZoneFile::Fast -E 'Net::DNS::ZoneFile::Fast::parse( file => shift, on_error => sub { say "on_error called: @_" }, soft_errors => 1, zone => "example.org" ); say "OK"' /etc/shadow cannot open /etc/shadow: Permission denied, line 0 … does not: The on_error handler does not get called, and the script dies though soft_errors is set. Please let me know if you are interested in a patch for this issue. Regards, fany
