From f7d542b028767422ef8fa343b97e749f04ffa293 Mon Sep 17 00:00:00 2001 From: Julian Maurice Date: Wed, 13 Nov 2013 14:21:40 +0100 Subject: [PATCH] [SIGNED OFF] Bug 11701: Fix C4::Context::Zconn When calling C4::Context::Zconn twice with different parameters, the same ZOOM::Connection object is returned twice (parameters of 2nd call are not used) This patch fixes that. This is in part, because the connection cache is keyed on server name only. This patch corrects this by keying on all parameters. TEST PLAN --------- 1) apply patch 2) run koha qa test tools 3) prove -v t/Context.t The unit tests properly triggers the modified routine for testing. Additionally, in hunting for ways it could break, no nested synchronous or asynchronous Zconn's were found. And even if they were, the keying on all parameters should allow it to function properly without messing up the other connection.
