From 5e3fa9831c4f8656dc26b311ec239b17193bd217 Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Mon, 18 Oct 2021 12:28:27 +0000 Subject: [PATCH] Bug 29264: SIP config allows use of non-branchcode institution ids causes workers to die without responding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If is entirely possible to create an SIP institution whose ID does not match a valid branchcode in Koha's SIP config. In fact, Koha's example SIP config contains an example of this ( kohalibrary / kohalibrary2 ). If a SIP login uses an institution with an id that doesn't match a valid branchcode, everything will appear to work, but the SIP worker will die anywhere that Koha gets the branch from the userenv and assumes it is valid. The repercussions of this are that actions such as the checkout message simply die and do not return a response message to the requestor. At the very least, we should output a warning to the SIP log. I think we should strongly consider disallowing institution ids in the SIP config that do not match valid branchcodes. In this scenario, attempting to start the SIP server should result in a error message with the SIP server exiting immediately. Test Plan: 1) Apply this patch 2) Make a sip login that uses an instution whose id is *not* a valid branchcode 3) Start the SIP server 4) Check sip.log, you should see a warning similar to the following: [2021/10/18 12:18:29] [2068079] [ERROR] ERROR: Institution kohalibrary does does not match a branchcode. This can cause unexpected behavior.
