( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I stumbled across a bug in my code that I tracked down to something I am doing with a DBM::Deep file. When I assign the inner key of a DBM hash-of-hrefs to another variable and then try to delete the file, I get an error when the inner key is a href but not when it is a non-ref scalar.

use strict; use warnings; use DBM::Deep; my $db_file = 'href_nocopy'; { my $db = DBM::Deep->new( $db_file ); $db->{key} = {}; } print "\nDeleting $db_file\n"; unlink( $db_file ) || warn $!; # succeeds $db_file = 'href_copy'; { my $db = DBM::Deep->new( $db_file ); $db->{key} = {}; my $db2 = $db->{key}; } print "\nDeleting $db_file\n"; unlink( $db_file ) || warn $!; # fails (permission denied) $db_file = 'nonref_copy'; { my $db = DBM::Deep->new( $db_file ); $db->{key} = 1; my $db2 = $db->{key}; } print "\nDeleting $db_file\n"; unlink( $db_file ) || warn $!; # succeeds

Any ideas? I didn't find any documentation about this elsewhere.

Thanks

  • Are you posting in the right place? Check out Where do I post X? to know for sure.

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
