From ee7969d3461e6ce08b4fbfd982c90f263f19f693 Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Tue, 20 Jun 2017 15:03:35 +0200 Subject: [PATCH] Bug 18651: [QA Follow-up] Fix the MAX(issue_id) calculation Found this by inserting the same issue_id in old_issues before checkin: The call to ->search( )->get_column is in scalar context and will return the number of results, i.e. always 1. If you have an issue_id 2 in old_issues, it will crash: DBIx::Class::Storage::DBI::_dbh_execute(): Duplicate entry '2' for key 'PRIMARY' The fix is fairly simple: Put get_column in list context and pick the first array entry. NOTE: Using DBIx's get_column()->max here might look simpler here.
