marko 0efd5d663e Reduce the size of btr_search_t from 13 machine words to 7. This ... structure is reserved for every index in the data dictionary cache. (Bug #20877) We could shrink the structure further to three 32-bit words or two 64-bit words by turning the remaining fields to bit-fields. Unfortunately, the fields are not protected by any mutex, and thus we would better keep each field aligned to a machine word. btr_search_t, buf_block_t: Rename "ulint side" to "ibool left_side". Remove BTR_SEARCH_LEFT_SIDE and BTR_SEARCH_RIGHT_SIDE, and also rename some local variables and function parameters from "ulint side" to "ibool left_side". btr_search_t: Remove the unused fields last_search, n_direction, direction, and modify_clock. Remove the unused constants BTR_SEA_NO_DIRECTION, BTR_SEA_LEFT, BTR_SEA_RIGHT, and BTR_SEA_SAME_REC. btr_search_t: Remove magic_n unless #defined UNIV_DEBUG. Turn an assertion about the magic number into a debug assertion.		2006-09-14 20:42:46 +00:00
