Our intention is to make users aware that the ROW_FORMAT=COMPRESSED format is on its way to deprecation. It is an unnecessary annoyance to users if we issue a warning when the user is converting a ROW_FORMAT=COMPRESSED table to a supported format (such as ROW_FORMAT=DYNAMIC). ha_innobase::is_read_only(): Add a parameter to specify that an ALTER TABLE to a supported format has been requested. ha_innobase::check_if_supported_inplace_alter(): Set the parameter when ALTER_OPTIONS to something else than ROW_FORMAT=COMPRESSED (and without KEY_BLOCK_SIZE) is being requested. Thanks to Elena Stepanova for suggesting this.
