https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=30638 Bug ID: 30638 Summary: Odd number of elements in anonymous hash at C4/Letters.pm line 827 Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Architecture, internals, and plumbing Assignee: koha-bugs@lists.koha-community.org Reporter: m.de.rooy@rijksmuseum.nl QA Contact: testopia@bugs.koha-community.org Originating from 20.11 warnings: Odd number of elements in anonymous hash at C4/Letters.pm line 878 output_pref({ dt => dt_from_string( $replacedby ), dateonly => $dateonly }); This is line 827 on current master. If dt_from_string returns undef in list context, we get the odd number warn. Also note the following lines: if ( $letter->{ $letter_field } ) { $letter->{ $letter_field } =~ s/\Q<<$table.$field$filter_string_used>>\E/$replacedby_date/g; $letter->{ $letter_field } =~ s/\Q<<$field$filter_string_used>>\E/$replacedby_date/g; If output_pref should correctly return undef on a NULL from dt_from_string, the undefined result triggers two warnings in the regexes. -- You are receiving this mail because: You are the assignee for the bug.
