Hi,

I'm developing monitoring tool in daemon plugin

I'm tyring to access pfs table via low level interface not using sql.

 (see below)

-------------------------------------------------------------------------------------

.....

 tables.init_one_table(STRING_WITH_LEN("performance_schema"), STRING_WITH_LEN("events_statements_current"),
                                                                                        "events_statements_current", TL_READ);
 bool result = open_and_lock_tables(ctx->thd, &tables, FALSE, MYSQL_LOCK_IGNORE_TIMEOUT);
if (result)
{
       sql_print_error("monm plugin error: Can't open the %s.%s table.",dbname,tblname);
}
.....

/* read routine */

------------------------------------------------------------

In open_and_lock_table function, I hava a error.

I found the reason of this error by debugging.

In table_cache.cc, open_table_def()  requires .frm file  as a table definition.

but above version 10.1.3, there is no frm file for pfs table as I know. right?

Let me know a correct way to get data from  pfs table not using sql.

Regards,

Kyungnam.
