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.
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.
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.
Do not pad VARBINARY or BINARY columns. (Bug #14189)
innodb.test, innodb.result: Add test cases for foreign key constraints
between VARBINARY and BINARY columns, and between VARCHAR BINARY and
CHAR BINARY columns.
innobase_init(): Assert that
DATA_MYSQL_BINARY_CHARSET_COLL == my_charset_bin.number.
dtype_get_pad_char(): Do not pad VARBINARY or BINARY columns.
row_ins_cascade_calc_update_vec(): Refuse ON UPDATE CASCADE
when trying to change the length of a VARBINARY column
that refers to or is referenced by a BINARY column. BINARY
columns are no longer padded on comparison, and thus they
cannot be padded on storage either.
