From 03c03ed8cdb94cda4cfd661e3b04f97cb36d8dc4 Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Tue, 1 May 2018 11:47:12 +0000 Subject: [PATCH] Bug 15253: Add Koha::Logger based logging for SIP2 Now that we have Koha::Logger, we should use it in our SIP server. This has the potential to make debugging SIP issue much easier. We should add the userid for the sipuser to the namespace so we can allow for separate files per sip user if wanted. Also modifies the log4perl.conf to lazy-open filehandles to log files, so the same config can be used with log-files needing different permissions. Test Plan: 1) Apply this patch set 2) Update the modififed log4perl.conf to your system 3) Restart your sip server 4) Tail your sip2.log, run some queries 5) Note you still get the same output messages as before, with the addition of the ip address and username ( if available ) prefixing the message. Based on original patches by Kyle Hall and additions by Olli-Antti Kivilahti.
