From dc4fd43f39db79de2201bf428a35a56fc3070eac Mon Sep 17 00:00:00 2001 From: Roeland Jago Douma Date: Fri, 27 May 2016 10:32:19 +0200 Subject: [PATCH] Use a capped memory cache for the user/group cache For #24403 When upgrading huge installations this can lead to memory problems as the cache will only grow and grow. Capping this memory will make sure we don't run out while during normal operation still basically cache everything. --- apps/user_ldap/lib/Group_LDAP.php | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/apps/user_ldap/lib/Group_LDAP.php b/apps/user_ldap/lib/Group_LDAP.php index 27bbcfffd6..7c12613f34 100644 --- a/apps/user_ldap/lib/Group_LDAP.php +++ b/apps/user_ldap/lib/Group_LDAP.php @@ -36,6 +36,7 @@ namespace OCA\User_LDAP; +use OC\Cache\CappedMemoryCache; class Group_LDAP extends BackendUtility implements \OCP\GroupInterface { protected $enabled = false; @@ -43,12 +44,12 @@ class Group_LDAP extends BackendUtility implements \OCP\GroupInterface { /** * @var string[] $cachedGroupMembers array of users with gid as key */ - protected $cachedGroupMembers = array(); + protected $cachedGroupMembers; /** * @var string[] $cachedGroupsByMember array of groups with uid as key */ - protected $cachedGroupsByMember = array(); + protected $cachedGroupsByMember; public function __construct(Access $access) { parent::__construct($access); @@ -57,6 +58,9 @@ class Group_LDAP extends BackendUtility implements \OCP\GroupInterface { if(!empty($filter) && !empty($gassoc)) { $this->enabled = true; } + + $this->cachedGroupMembers = new CappedMemoryCache(); + $this->cachedGroupsByMember = new CappedMemoryCache(); } /**
