From 4dbb894dfdbae1cee873039ffe016cdc13938266 Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Wed, 2 May 2018 16:13:20 +0200 Subject: [PATCH] Bug 20696: Fix a few ugly "eq undef" comparisons in Search.pm Comparisons like $a eq undef should normally raise a warning like: Use of uninitialized value in string eq at ... But unfortunately we still suppress warnings here and there. Test plan: [1] Just read this patch and confirm the small changes. [2] Git grep on "eq undef" and do not find other occurrences. Signed-off-by: Marcel de Rooy Signed-off-by: Owen Leonard Passes test plan and QA tools. Searching works correctly.
