From 240d0633b39563ac86aa1beecbdebb02e0aeef13 Mon Sep 17 00:00:00 2001 From: Ramil Kalimullin Date: Thu, 20 Nov 2008 14:08:36 +0400 Subject: [PATCH] Fix for bug#40875: Memory leak in FEDERATED handler Problem: memory leak occurs when we open a federated table that has its share in the hash. Fix: free not used memory. Note: the fix should NOT be merged to 5.1 (the code changed). --- sql/ha_federated.cc | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/sql/ha_federated.cc b/sql/ha_federated.cc index b4788dd9c87..d4144a41a2a 100644 --- a/sql/ha_federated.cc +++ b/sql/ha_federated.cc @@ -1320,6 +1320,14 @@ static FEDERATED_SHARE *get_share(const char *table_name, TABLE *table) thr_lock_init(&share->lock); pthread_mutex_init(&share->mutex, MY_MUTEX_INIT_FAST); } + else + { + /* + Free tmp_share.scheme allocated in the parse_url() + as we found share in the hash and tmp_share isn't needed anymore. + */ + my_free((gptr) tmp_share.scheme, MYF(MY_ALLOW_ZERO_PTR)); + } share->use_count++; pthread_mutex_unlock(&federated_mutex);
