-----Original Message----- From: Dintelmann, Peter [mailto:Peter.Dintelmann@Dresdner-Bank.com] Sent: 05 December 2003 15:19 To: 'Paul.Marquess@btinternet.com' Subject: DB_File delete in tied hash Hi Paul, when using a hash tied to DB_File I observed that deleting a non-existent element from the hash returns -30990. $ perl -MDB_File -le 'tie my %h, "DB_File"; print delete $h{x}' -30990 $ perl -MDB_File -le 'print $DB_File::VERSION' 1.807 However perlfunc(1) states that delete() returns undef if the specified element does not exist. Can you change this?

Hi Peter I've moved your request to the CPAN bug queue. See https://rt.cpan.org/Ticket/Display.html?id=4629 for details. Regarding yourrequest, I'm in two minds about it. Yes, the existing behaviour doesn't match the man page, but the existing (broken) functionality has been like that for years and I don't want to break any scripts that assume the broken functionality. Also, this would only be a partial fix, because "delete $h{$x}" is supposed to return the value deleted. It doesn't for DB_File. Let me run this one past the perl5-porters and see if anyone else has an opinion on this. cheers Paul Show quoted text
