From 095dc81158902380b8618338efabb5ce480dbd79 Mon Sep 17 00:00:00 2001 From: Igor Babaev Date: Sun, 15 Jul 2018 16:24:24 -0700 Subject: MDEV-16757 Memory leak after adding manually min/max statistical data for blob column ANALYZE TABLE does not collect statistical data on min/max values for BLOB columns of
. However these values can be added into mysql.column_stats manually by executing proper statements. Unfortunately this led to a memory leak because the memory allocated for these values was never freed. This patch provides the server with a function to free memory allocated for min/max statistical values of BLOB types. Temporarily changed the test case until MDEV-16711 is fixed as without this fix the test case for MDEV-16757 did not fail only for 10.0. --- sql/sql_statistics.h | 1 + 1 file changed, 1 insertion(+) (limited to 'sql/sql_statistics.h') diff --git a/sql/sql_statistics.h b/sql/sql_statistics.h index f46583839d1..0611c021e88 100644 --- a/sql/sql_statistics.h +++ b/sql/sql_statistics.h @@ -92,6 +92,7 @@ int read_statistics_for_tables_if_needed(THD *thd, TABLE_LIST *tables); int collect_statistics_for_table(THD *thd, TABLE *table); int alloc_statistics_for_table_share(THD* thd, TABLE_SHARE *share, bool is_safe); +void delete_stat_values_for_table_share(TABLE_SHARE *table_share); int alloc_statistics_for_table(THD *thd, TABLE *table); int update_statistics_for_table(THD *thd, TABLE *table); int delete_statistics_for_table(THD *thd, LEX_STRING *db, LEX_STRING *tab); -- cgit v1.2.1
