Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work. client/mysql_upgrade.c: Added option -V, --version debian/dist/Debian/mariadb-server-5.5.files: Added mysql_performance_tables.sql debian/dist/Ubuntu/mariadb-server-5.5.files: Added mysql_performance_tables.sql mysql-test/lib/v1/mysql-test-run.pl: Added mysql_performance_tables.sql mysql-test/mysql-test-run.pl: Added mysql_performance_tables.sql scripts/CMakeLists.txt: Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work scripts/mysql_install_db.sh: Added mysql_performance_tables.sql scripts/mysql_performance_tables.sql: Moved out creation of performance schema tables from mysql_system_tables.sql as the performance_tables creation scripts needs a working mysql.proc to work scripts/mysql_system_tables.sql: Move creation of performance schema tables to mysql_performance_tables.sql Added 'flush tables' to get things to work if someone deletes a table like mysql.proc before run scripts/mysql_system_tables_fix.sql: ove performance table things to mysql_performance_tables.sql storage/perfschema/pfs.cc: Fixed comment
