From 02234783c6f0fd9b15faf7a17d3bb8b1d39da557 Mon Sep 17 00:00:00 2001 From: v12mike Date: Sun, 15 Jul 2018 21:50:18 +0100 Subject: [ticket/15726] Implement selective purge in APCu cache driver The current APCu cache driver implements a global clearing of the APCu when the phpBB cache is purged. This is inappropriate if there are other phpBB boards, or other php applications sharing the APCu cache. This patch changes the behviour so that only cache entries matching the key_prefix of this board are cleared by a phpBB cache purge. The APCu unit test script has been updated to test this behaviour. It has also been updated so that the test case can be run individually previously it relied on initialisations made in other test scripts.
