Bugs fixed: - Bug #20877: InnoDB data dictionary memory footprint is too big - Bug #13544: Second delete of same row in transaction illustrates non-optimal locking - Bug #20791: valgrind errors in InnoDB storage/innobase/btr/btr0btr.c: Applied innodb-5.1 snapshots ss799 and ss854 Revision r823: Minor cleanup related to Bug #20877. btr_print_recursive(): Replace tree->tree_indexes with tree->index. This should have been done in r453. univ.i: Add UNIV_BTR_PRINT. rw_lock_t: Reduce writer_is_wait_ex to a bit and move it close to other bitfields. Change the types to unsigned, in case ulint or ibool bitfields will not work. Revision r828: Remove dict_tree_t, which should have been removed in r453. There always was a one-to-one mapping between dict_tree_t and dict_index_t. This saves 6 machine words per B-tree index in the data dictionary cache plus the memory allocation overhead. We save one mem_heap_t object per index (15 machine words). Considering the internal fragmentation of the buddy allocator in mem_area_alloc(), this should save 32 machine words per index (128 bytes on 32-bit systems and 256 bytes on 64-bit systems).

Revision r832: Add dict_table_get_col_name() in preparation for getting rid of dict_col_t::name, and use it instead of col->name everywhere. Revision r833: Tweak the bit-field definitions introduced since r813 to address Bug #20877. rw_lock_t: Do not make writer_is_wait_ex a bit-field. There are no fields yet that could be fused to the same machine word, but we play it safe, because the field writer_is_wait_ex may be modified by several threads simultaneously. Such fields should always be allocated an own machine word. dict_table_t: Change the type of all bit-fields to "unsigned". Make "space" a bit-field of 32 bits. Move name_hash and id_hash after all bit-fields, so that the bit-fields can be allocated together. Do not make autoinc_inited a bit-field, as we cannot allocate any field from the same machine word. dict_build_table_def_step(): Pass a local variable to fil_create_new_single_table_tablespace() and initialize table->space from it after the call, now that table->space is a bit-field. Revision r834: dict_col_t: Copy the fields of "dtype_t type" directly to this structure, so that all integer fields can be packed into 64 bits.

Revision r816: Remove more remnants of mixed indexes. Revision r818: Remove dict_col_t::hash, dict_col_t::table, dict_sys->col_hash, and DICT_POOL_PER_COL_HASH. (Bug #20877) The col->table pointer was only needed for maintaining a hash table of all defined columns in all tables. The hash table was only looked up in dict_index_find_cols(). Removing the col->hash and col->table pointers reduces the size of a table column by two machine words (usually 8 or 16 bytes). dict_col_add_to_cache(), dict_col_reposition_in_cache(), dict_col_remove_from_cache(): Remove. These only updated dict_sys->col_hash. dict_index_find_cols(): Use a linear search instead of the hash table. The time complexity is affected, but this function is only invoked by dict_index_add_to_cache(), and we only search the columns of a single table (typically at most a few dozen) as opposed to all columns of all tables. Revision r819: dict_col_t: Reduce ord_part to one bit. dict_index_add_to_cache(): Instead of incrementing ord_part, set it. dict_index_remove_from_cache(): Do not touch ord_part. dtype_t: Reduce mbminlen from 3 to 2 bits. row_upd(): Add a UNIV_LIKELY hint around node->in_mysql_interface. Revision r820: Remove dict_col_t::clust_pos. dict_col_get_clust_pos(): Add parameter clust_index. Replace the look-up with a linear search of all columns in the clustered index. row_upd_index_replace_new_col_vals(): Compute clust_index outside the loops. Compute clust_pos outside the inner loop. row_upd_changes_ord_field_binary(), row_upd_changes_first_fields_binary(): Compute clust_index outside the loops. Declare the auxiliary variables inside the loop scope. Revision r821: dict_table_t: Rename the integer field max_row_size to the Boolean field big_rows. (Bug #20877) BIG_ROW_SIZE: Move the definition from row0sel.c to dict_table_add_to_cache(). Revision r826: The code base was reindented in r763 and automatic .emacs indentation settings introduced. Some problems were found, so from this commit on one additional indentation rule is introduced: (add-to-list 'c-offsets-alist '(arglist-intro . +)) Note that fixing some of the unfortunate line-splits done in r764 will be done in a future change. Revision r827: Make dict_index_find_cols() always succeed. Revision r828: Remove dict_tree_t, which should have been removed in r453. There always was a one-to-one mapping between dict_tree_t and dict_index_t. This saves 6 machine words per B-tree index in the data dictionary cache plus the memory allocation overhead. We save one mem_heap_t object per index (15 machine words). Considering the internal fragmentation of the buddy allocator in mem_area_alloc(), this should save 32 machine words per index (128 bytes on 32-bit systems and 256 bytes on 64-bit systems).

Revision r818: Remove dict_col_t::hash, dict_col_t::table, dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.

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.

Revision r818: Remove dict_col_t::hash, dict_col_t::table, dict_sys->col_hash, and DICT_POOL_PER_COL_HASH. (Bug #20877) The col->table pointer was only needed for maintaining a hash table of all defined columns in all tables. The hash table was only looked up in dict_index_find_cols(). Removing the col->hash and col->table pointers reduces the size of a table column by two machine words (usually 8 or 16 bytes). dict_col_add_to_cache(), dict_col_reposition_in_cache(), dict_col_remove_from_cache(): Remove. These only updated dict_sys->col_hash. dict_index_find_cols(): Use a linear search instead of the hash table. The time complexity is affected, but this function is only invoked by dict_index_add_to_cache(), and we only search the columns of a single table (typically at most a few dozen) as opposed to all columns of all tables. Revision r820: Remove dict_col_t::clust_pos. dict_col_get_clust_pos(): Add parameter clust_index. Replace the look-up with a linear search of all columns in the clustered index. row_upd_index_replace_new_col_vals(): Compute clust_index outside the loops. Compute clust_pos outside the inner loop. row_upd_changes_ord_field_binary(), row_upd_changes_first_fields_binary(): Compute clust_index outside the loops. Declare the auxiliary variables inside the loop scope. Revision r827: Make dict_index_find_cols() always succeed. Revision r828: Remove dict_tree_t, which should have been removed in r453. There always was a one-to-one mapping between dict_tree_t and dict_index_t. This saves 6 machine words per B-tree index in the data dictionary cache plus the memory allocation overhead. We save one mem_heap_t object per index (15 machine words). Considering the internal fragmentation of the buddy allocator in mem_area_alloc(), this should save 32 machine words per index (128 bytes on 32-bit systems and 256 bytes on 64-bit systems). (Bug #20877) struct dict_tree_struct, dict_tree_t: Remove. struct dict_index_struct: Add page and lock. dict_tree_create(): Remove.

Replace the occurrences of "tree" with "index" in names of variables, functions and data types, e.g. "dict_tree_t tree" becomes "dict_index_t index". Remove local variables "tree" or "index" of functions that needed both "tree" and "index". Revision r831: Add dict_col_get_clust_pos_noninline(), which was forgotten from r820.

Revision r833: Tweak the bit-field definitions introduced since r813 to address Bug #20877. rw_lock_t: Do not make writer_is_wait_ex a bit-field. There are no fields yet that could be fused to the same machine word, but we play it safe, because the field writer_is_wait_ex may be modified by several threads simultaneously. Such fields should always be allocated an own machine word. dict_table_t: Change the type of all bit-fields to "unsigned". Make "space" a bit-field of 32 bits. Move name_hash and id_hash after all bit-fields, so that the bit-fields can be allocated together. Do not make autoinc_inited a bit-field, as we cannot allocate any field from the same machine word. dict_build_table_def_step(): Pass a local variable to fil_create_new_single_table_tablespace() and initialize table->space from it after the call, now that table->space is a bit-field.

There always was a one-to-one mapping between dict_tree_t and dict_index_t. This saves 6 machine words per B-tree index in the data dictionary cache plus the memory allocation overhead. We save one mem_heap_t object per index (15 machine words). Considering the internal fragmentation of the buddy allocator in mem_area_alloc(), this should save 32 machine words per index (128 bytes on 32-bit systems and 256 bytes on 64-bit systems). (Bug #20877) struct dict_tree_struct, dict_tree_t: Remove. struct dict_index_struct: Add page and lock. dict_tree_create(): Remove. Replace the invocation with assignment to index->page and a call to rw_lock_create(&index->lock). dict_tree_free(): Remove. Replace the invocation wtih a call to rw_lock_free(&index->lock). dict_index_get_tree(): Remove. dict_tree_get_space_reserve(): Rename to dict_index_get_space_reserve() and remove the parameter, which was unused. btr_level_list_remove(): Remove the unused parameter "tree". Replace the occurrences of "tree" with "index" in names of variables, functions and data types, e.g. "dict_tree_t tree" becomes "dict_index_t index". Remove local variables "tree" or "index" of functions that needed both "tree" and "index". storage/innobase/include/ibuf0ibuf.ic: Applied innodb-5.1 snapshots ss799 and ss854 Revision r838: Revamp the line splits done in r763 and r764 that can now be done better, thanks to r826. storage/innobase/include/page0page.h: Applied innodb-5.1 snapshots ss799 and ss854 Revision r830: page_align(ptr): New utility function to replace ut_align_down(ptr, UNIV_PAGE_SIZE) calls.

Change the types to unsigned, in case ulint or ibool bitfields will not work. Revision r833: Tweak the bit-field definitions introduced since r813 to address Bug #20877. rw_lock_t: Do not make writer_is_wait_ex a bit-field. There are no fields yet that could be fused to the same machine word, but we play it safe, because the field writer_is_wait_ex may be modified by several threads simultaneously. Such fields should always be allocated an own machine word. dict_table_t: Change the type of all bit-fields to "unsigned". Make "space" a bit-field of 32 bits. Move name_hash and id_hash after all bit-fields, so that the bit-fields can be allocated together. Do not make autoinc_inited a bit-field, as we cannot allocate any field from the same machine word. dict_build_table_def_step(): Pass a local variable to fil_create_new_single_table_tablespace() and initialize table->space from it after the call, now that table->space is a bit-field. storage/innobase/include/univ.i: Applied innodb-5.1 snapshots ss799 and ss854 Revision r823: Minor cleanup related to Bug #20877. btr_print_recursive(): Replace tree->tree_indexes with tree->index.

Move REC_MAX_N_FIELDS (and REC_MAX_HEAP_NO and REC_MAX_N_OWNED) from rem0rec.c to rem0types.h, as they are needed in dict0dict.ic. dict_col_get_clust_pos(): Map REC_MAX_N_FIELDS to ULINT_UNDEFINED. storage/innobase/sync/sync0sync.c: Applied innodb-5.1 snapshots ss799 and ss854 Revision r838: Revamp the line splits done in r763 and r764 that can now be done better, thanks to r826. storage/innobase/trx/trx0purge.c: Applied innodb-5.1 snapshots ss799 and ss854 Revision r838: Revamp the line splits done in r763 and r764 that can now be done better, thanks to r826. storage/innobase/trx/trx0rec.c: Applied innodb-5.1 snapshots ss799 and ss854 Revision r834: dict_col_t: Copy the fields of "dtype_t type" directly to this structure, so that all integer fields can be packed into 64 bits. (Bug #20877) dtype_t: Change the type of all bit-fields to unsigned. dict_table_get_nth_col(), dict_table_get_sys_col_noninline(), dict_table_get_sys_col(), dict_field_get_col(): Return const dict_col_t*, so that changes to dict_col_t can be detected more easily. Add const to many dict_col_t* declarations. dict_index_get_nth_type(): Replace with dict_index_get_nth_col(). dict_col_get_type(): Replace with dict_col_copy_type(). dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(), dict_col_get_sql_null_size(): New functions. dtype_get_at_most_n_mbchars(): Replace the parameter dtype with the parameters prtype, mbminlen, mbmaxlen. dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(), cmp_whole_field(): Replace the dtype_t* parameter with the ulint parameters mtype, prtype. dtype_copy(): Add a const qualifier to type2 (the one being copied from). dtype_set_mblen(): Replaced with dtype_get_mblen(). dtype_get_fixed_size_low(), dtype_get_min_size_low(), dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(), dtype_get_min_size(), and dtype_get_max_size(). These are used by the dict_col_get_{fixed,min,max}_size() functions. cmp_types_are_equal(): Replace with cmp_cols_are_equal(). dict_table_get_col_name(): Add a const qualifier parameter to the parameter "table". dtype_binary, dtype_binary_val: Remove. dtype_is_fixed_size(): Remove.
