Basic idea of the patch: disallow creating tables which allow to create rows which are too big to insert. In other words, if user created a table user should never see an errors like 'can not insert row as it is too big for current page size'. SET innodb_strict_mode=OFF; will allow to create very long tables and only a warning will be issued. dict_table_t::get_overflow_field_local_len(): this function lets know a maximum local field len for overflow fields for every file and row format. innobase_check_column_length(): improve name to too_big_key_part_length() and reuse in a different part of code. create_table_info_t::prepare_create_table(): add check for maximum allowed key part length to keep ALGORITHM=COPY behavior similar to ALGORITHM=INPLACE behavior. Affected test is innodb.strict_mode Rename dict_index_too_big_for_tree() to dict_index_t::rec_potentially_too_big(): copy overflow-related size computation from dtuple_convert_big_rec(). A lot of tests was changed because of that. I wonder whether users will complain about it? Test innodb.max_record_size tests dict_index_t::rec_potentially_too_big() for different row formats and page sizes.
