From 699a87110d397def13d783bc89c37f9b012f175a Mon Sep 17 00:00:00 2001 From: unknown Date: Thu, 3 Dec 2009 17:15:47 +0100 Subject: [PATCH] This is a patch for bug#41569. "mysql_upgrade (ver 5.1) add 3 fields to mysql.proc table but does not set values". mysql_upgrade (ver 5.1) adds 3 fields (character_set_client, collation_connection and db_collation) to the mysql.proc table, but does not set any values. When we run stored procedures, which were created with mysql 5.0, a warning is logged into the error log. The solution to this is for mysql_upgrade to set default best guess values for these fields. A warning is also written during upgrade, to make the user aware that default values are set. client/mysql_upgrade.c: Result lines which start with "WARNING" are passed through to the output. This way we have a way of triggering WARNING-messages during upgrade directly from the .sql-script. mysql-test/r/mysql_upgrade.result: Expected result of the test. mysql-test/t/mysql_upgrade.test: Added a test-case for the bug. scripts/mysql_system_tables_fix.sql: The new fields are populated, and warnings are written. --- client/mysql_upgrade.c | 4 +++ mysql-test/r/mysql_upgrade.result | 42 +++++++++++++++++++++++++++++ mysql-test/t/mysql_upgrade.test | 17 ++++++++++++ scripts/mysql_system_tables_fix.sql | 30 +++++++++++++++++++++ 4 files changed, 93 insertions(+) diff --git a/client/mysql_upgrade.c b/client/mysql_upgrade.c index 52c3636219d..81dcdaa71f1 100644 --- a/client/mysql_upgrade.c +++ b/client/mysql_upgrade.c @@ -778,6 +778,10 @@ static int run_sql_fix_privilege_tables(void) found_real_errors++; print_line(line); } + else if (strncmp(line, "WARNING", 7) == 0) + { + print_line(line); + } } while ((line= get_line(line)) && *line); } diff --git a/mysql-test/r/mysql_upgrade.result b/mysql-test/r/mysql_upgrade.result index 384442f8c31..72917988594 100644 --- a/mysql-test/r/mysql_upgrade.result +++ b/mysql-test/r/mysql_upgrade.result @@ -127,3 +127,45 @@ mysql.time_zone_transition OK mysql.time_zone_transition_type OK mysql.user OK set GLOBAL sql_mode=default; +# +# Bug #41569 mysql_upgrade (ver 5.1) add 3 fields to mysql.proc table +# but does not set values. +# +CREATE PROCEDURE testproc() BEGIN END; +UPDATE mysql.proc SET character_set_client = NULL WHERE name LIKE 'testproc'; +UPDATE mysql.proc SET collation_connection = NULL WHERE name LIKE 'testproc'; +UPDATE mysql.proc SET db_collation = NULL WHERE name LIKE 'testproc'; +WARNING: NULL values of the 'character_set_client' column ('mysql.proc' table) have been updated with a default value (latin1).
