The creation of the primary key does not work. We will have to flag externally stored columns and copy the externally stored part from the old table. row_build_index_for_mysql(): Rename to row_merge_build_indexes(). Move from row0mysql.c to row0merge.c. Remove private declarations from row0merge.h. Make many functions static in row0merge.c. cmp_rec_rec_simple(): A new comparison function. dict_index_get_min_size(): New function. OS_FILE_FROM_FD(fd): A macro for converting from int to os_file_t. rec_convert_dtuple_to_rec_comp(): Make the interface lower-level. rec_get_converted_size_comp(): Return also extra_size. UT_SORT_FUNCTION_BODY(): Remove reference to an obsolete test program. row_rec_to_index_entry_low(): New function. row0merge.c: Implement merge sort based on file streams instead of fixed-size blocks. Sort the small blocks as arrays of dfield_t*, because it is faster than invoking rec_get_offsets() for every comparison.
