mariadb/storage/connect/mycat.h
Olivier Bertrand 213ecbbb4f - In info, the file length sometimes could not be caculated because the
catalog data path had not been set. This was added into ha_connect::info.
modified:
  storage/connect/ha_connect.cc

- All the functions querying table options could return information from the wrong
  table when several CONNECT tables were used in the same query (for instance joined
  together) This was because they belonged to the catalog class that is shared between
  all tables in the same query. They have been moved from the catalog class to the
  TABDEF/RELDEF class that is attached to each table. This was a major potential bug.
