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). (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).

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".
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)

Revision r816:
Remove more remnants of mixed indexes.
Revision r824:
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

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)

functions that needed both "tree" and "index".
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:

dtype_t: Remove unused field "prec", which was supposed to be used for
the precision of decimal columns in stand-alone InnoDB.
dtype_get_prec(): Remove.
dtype_set(), dict_mem_table_add_col(): Remove parameter "prec".
dtype_t: Turn all fields (mtype, prtype, len, mbminlen, mbmaxlen, len)
into bit-fields.
dict_table_t, dict_index_t, dict_tree_t: Omit magic_n from non-debug builds.
dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
Replace the default clust_pos value ULINT_UNDEFINED with
REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
the accessor function dict_col_get_clust_pos().
dict_field_t: Turn prefix_len and fixed_len into bit-fields.
dict_tree_t: Remove pad[64].
dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
cached, flags, stat_initialized, and autoinc_inited into bit-fields.
Remove does_not_fit_in_memory from non-debug builds.
dict_index_t: Turn the fields trx_id_offset, n_user_defined_cols,
n_uniq, n_def, n_fields, n_nullable, and cached into bit-fields.
dict_foreign_struct: Turn n_fields and type into bit-fields.
rw_lock_t: Turn cline, last_s_line, and last_x_line into bit-fields.

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.
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). (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".
Revision r831:
Add dict_col_get_clust_pos_noninline(), which was forgotten from r820.
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 r834:

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(),

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.
Revision r836:
Remove dict_col_t::name, replace it with a packed array of column names in
dict_table_t. This saves 8-15+ bytes of memory per column on 64-bit
machines.
Revision r837:

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)

Unfortunately, the fields are not protected by any mutex, and thus we
would better keep each field aligned to a machine word.

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.

This saves 6 machine words per B-tree index in the data dictionary

object per index (15 machine words). Considering the internal

dict_col_get_clust_pos(): Map REC_MAX_N_FIELDS to ULINT_UNDEFINED.
Revision r815:
dict_index_t: Remove tree_indexes. It should have been removed in r453
when the list in dict_tree_t was replaced with the pointer tree_index.
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 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 invocation with
assignment to index->page and a call to rw_lock_create(&index->lock).

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".
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:

dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),

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.

Revision r813:
Reduce the size of the data dictionary cache. (Bug #20877)
dtype_t: Remove unused field "prec", which was supposed to be used for
the precision of decimal columns in stand-alone InnoDB.
dtype_get_prec(): Remove.
dtype_set(), dict_mem_table_add_col(): Remove parameter "prec".
dtype_t: Turn all fields (mtype, prtype, len, mbminlen, mbmaxlen, len)
into bit-fields.
dict_table_t, dict_index_t, dict_tree_t: Omit magic_n from non-debug builds.
dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
Replace the default clust_pos value ULINT_UNDEFINED with
REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
the accessor function dict_col_get_clust_pos().
dict_field_t: Turn prefix_len and fixed_len into bit-fields.
dict_tree_t: Remove pad[64].
dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
cached, flags, stat_initialized, and autoinc_inited into bit-fields.
Remove does_not_fit_in_memory from non-debug builds.
dict_index_t: Turn the fields trx_id_offset, n_user_defined_cols,
n_uniq, n_def, n_fields, n_nullable, and cached into bit-fields.
dict_foreign_struct: Turn n_fields and type into bit-fields.
rw_lock_t: Turn cline, last_s_line, and last_x_line into bit-fields.
Omit level unless #defined UNIV_SYNC_DEBUG.
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.
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 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.
