…Share() Handle the case in tabutil.cpp where GetTableShare() must report an error after open_table_def() has already failed. open_table_def() stores the underlying system error in s->open_errno before returning, so if opening the .frm file fails with ENOENT, that information is preserved on the share. We use these recorded values to determine the most appropriate error message: 1. s->error == OPEN_FRM_OPEN_ERROR indicates the table definition file failed to open. 2. s->open_errno == ENOENT indicates the failure was due to a "not found" condition. 3. check_db_dir_existence(db) then distinguishes whether the missing path corresponds to an unknown database, versus a generic open/share error.
