* it isn't "pfs" function, don't call it Item_func_pfs, don't use item_pfsfunc.* * tests don't depend on performance schema, put in the main suite * inherit from Item_str_ascii_func * use connection collation, not utf8mb3_general_ci * set result length in fix_length_and_dec * do not set maybe_null * use my_snprintf() where possible * don't set m_value.ptr on every invocation * update sys schema to use the format_pico_time() * len must be size_t (compilation error on Windows) * the correct function name for double->double is fabs() * drop volatile hack
