VARIABLE_VALUE field is decreased to 1024 symbols. (affected I_S tables: GLOBAL_VARIABLES, SESSION_VARIABLES, GLOBAL_STATUS, SESSION_STATUS). The only variable which can be longer than 1024 is init_connect. The variable will be truncated with warning. Additional fix: Added where condition filter which speed up queries which have where condition with expressions which use VARIABLE_NAME field. mysql-test/r/information_schema.result: test result mysql-test/r/show_check.result: result fix mysql-test/suite/funcs_1/r/is_columns_is.result: result fix mysql-test/t/information_schema.test: test case sql/sql_show.cc: VARIABLE_VALUE field is decreased to 1024 symbols.
