From aa023f1ec95319db8eda26b7088058ae3cf0797e Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Thu, 23 Feb 2017 10:02:57 +0100 Subject: [PATCH] Bug 17380: Add some checks around Authorities::Types->find Content-Type: text/plain; charset=utf-8 Resolves: Use of uninitialized value $biblio_fields in scalar chop at authorities/detail.pl line 212. Can't call method "authtypetext" on an undefined value at authorities/detail.pl line 216. Can't call method "authtypecode" on an undefined value at authorities/detail.pl line 180. NOTE: Some of these problems have actually been resolved now by bugs 18801 and 18811, but it is still better imo to have these checks. Test plan: [1] Verify unchanged behavior. Search for some authorities on authorities.pl and click on the details of a record. [2] Open an authorities detail page and change the authid in the URL to a not existing number. Instead of an internal server error, you should see a message like "The authority record you requested does not exist".
