dict_col_copy_type_noninline(): Remove the return statement.
Some compilers do not allow return expressions of void type.

innobase_start_or_create_for_mysql(): Do not cap srv_max_threads to 1000
on Windows.

Makefile.am (EXTRA_DIST): Add plug.in

innodb_unsafe_binlog, innodb_handler, innodb-big, innodb_cache-master,
innodb-deadlock, innodb_cache: Remove.  These have been renamed in the
MySQL tree.

  This patch adds handlerton passing to functions. NDB and Innodb still require a global hanlderton in the main code due to the nature of the sql_cache call back function (should be solveable... another patch).
  Partitioning now has a flag to allow disabling of engines from being compatible with partitioning. Cleaned up heap naming convention on panic call.

  In the handlerton, cursor creation function don't have an argument
  and so the engine calls current_thd to derive transaction information;
  instead we now pass THD to those functions, it looks more logical
  (it makes the implicit current_thd parameter more visible).

bug would only surface if the InnoDB SQL interpreter were used for
updating fixed-length columns.  Currently (as the UPD_NODE_NO_SIZE_CHANGE
flag is never set), cmpl_info can only be 0 or UPD_NODE_NO_ORD_CHANGE.
Luckily, UPD_NODE_NO_ORD_CHANGE is 1, and the condition was simplified
to !cmpl_info.

dict_index_build_node_ptr(): Correct a typo in a comment.

machines.

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.

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.

dict_col_t::name, and use it instead of col->name everywhere.

it should be redo-logged because the data structure is file-based;
this patch does not fix any bug; the original erase operation was added
in r781 to fix Valgrind Bug #20791

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".

delete-marked record in a clustered index where the search criteria is

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.

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.

to the Boolean field big_rows.  (Bug #20877)

BIG_ROW_SIZE: Move the definition from row0sel.c to dict_table_add_to_cache().

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.

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.

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.
