Merge and adjust a forgotten change to fix this bug. rb://393 approved by Jimmy Yang ------------------------------------------------------------------------ r3794 | marko | 2009-01-07 14:14:53 +0000 (Wed, 07 Jan 2009) | 18 lines branches/6.0: Allow the minimum length of a multi-byte character to be up to 4 bytes. (Bug #35391) dtype_t, dict_col_t: Replace mbminlen:2, mbmaxlen:3 with mbminmaxlen:5. In this way, the 5 bits can hold two values of 0..4, and the storage size of the fields will not cross the 64-bit boundary. Encode the values as DATA_MBMAX * mbmaxlen + mbminlen. Define the auxiliary macros DB_MBMINLEN(mbminmaxlen), DB_MBMAXLEN(mbminmaxlen), and DB_MINMAXLEN(mbminlen, mbmaxlen). Try to trim and pad UTF-16 and UTF-32 with spaces as appropriate. Alexander Barkov suggested the use of cs->cset->fill(cs, buff, len, 0x20). ha_innobase::store_key_val_for_row() now does that, but the added function row_mysql_pad_col() does not, because it doesn't have the MySQL TABLE object. rb://49 approved by Heikki Tuuri ------------------------------------------------------------------------
