the loops. Compute clust_pos outside the inner loop.
row_upd_changes_ord_field_binary(), row_upd_changes_first_fields_binary():

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)

Fix for BUG#20866 "show table status on innodb raises assertion"
and its duplicate BUG#19057 "Test 'rpl_row_func003' fails on SuSE SLES9 x86".
It was an assertion failure, only in debug builds, not present
in released versions (nothing to document).
It happened when doing SHOW TABLE STATUS on an InnoDB table
having an auto_increment column, right after creating the table.

Before a val_() calls on a Field object, if that field was not marked
for read, we need to mark it. This is explained here:
ChangeSet 1.2119.601.1 2006/06/04 18:52:22 monty@mysql.com
quoting the changeset's comment:
- If a handler needs to call Field->val() or Field->store() on columns
that are not used in the query, one should install a temporary
all-columns-used map while doing so. For this, we provide the following
functions:
my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->read_set);
field->val();
dbug_tmp_restore_column_map(table->read_set, old_map);
and similar for the write map:
my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->write_set);
field->val();
dbug_tmp_restore_column_map(table->write_set, old_map);
If this is not done, you will sooner or later hit a DBUG_ASSERT
in the field store() / val() functions.
(For not DBUG binaries, the dbug_tmp_restore_column_map() and
dbug_tmp_restore_column_map() are inline dummy functions and should
be optimized away be the compiler).
Note that I verified that the bug didn't exist in non-debug builds.

# First push for WL#3146 "less locking in auto_increment". It is a
# 0-real-change patch.
# New prototype for get_auto_increment() (but new arguments not yet used),
# to be able to reserve a finite interval of auto_increment values from
# cooperating engines.
# A hint on how many values to reserve is found in
# handler::estimation_rows_to_insert,
# filled by ha_start_bulk_insert(), new wrapper around start_bulk_insert().
# NOTE: this patch changes nothing, for all engines.
# But it makes the API ready for those
# engines which will want to do reservation.
# More csets will come to complete WL#3146.

# second patch for make distcheck
ha_innodb.cc: enclose in #ifdef WITH_INNOBASE_STORAGE_ENGINE / #endif
Fix bug #17264. For alter table on win32 for succesful operation completion
it is used TL_WRITE(=10) lock instead of TL_WRITE_ALLOW_READ(=6), however in
InnoDB handler TL_WRITE is lifted to TL_WRITE_ALLOW_WRITE, which causes race
condition when several clients do alter table simultaneously.
ut_print_name(), ut_print_namel(): Add parameter table_id for distinguishing
names of tables from other identifiers (names of indexes, columns and
constraints).
innobase_convert_from_table_id(), innobase_convert_from_id(),
innobase_convert_from_filename(), innobase_get_charset(): New functions.
dict_accept(), dict_scan_id(), dict_scan_col(), dict_scan_table_name(),
dict_skip_word(), dict_create_foreign_constraints_low():
Add parameter "cs", so that isspace() can be replaced with my_isspace(),
whose operation depends on the connection character set.
dict_scan_id(): Convert the identifier to UTF-8.
dict_str_starts_with_keyword(): New extern function, to replace dict_accept()
in row_search_for_mysql().
mysql_get_identifier_quote_char(): Replaced with innobase_print_identifier().
ha_innobase::create(): Remove the thd->convert_string() call.
Pass the statement to InnoDB in the connection character set
and let InnoDB convert the identifiers to UTF-8.
Remove unused dict_table_LRU_trim().
Remove unused 'trx' parameter from the functions dict_table_get_on_id_low,
dict_table_get and dict_table_get_and_increment_handle_count.
weakens the locks for this session similarly like the option
innodb_locks_unsafe_for_binlog. This patch removes almost all
gap locking (used in next-key locking) and makes MySQL to release
the row locks on the rows which does not belong to result set.
Additionally, nonlocking selects on INSERT INTO SELECT,
UPDATE ... (SELECT ...), and CREATE ... SELECT ... use a
nonlocking consistent read. If a binlog is used, then binlog
format should be set to row based binloging to make the execution
of the complex SQL statements.

valid after calling this function.
r338: Fix bug 18238 : check in pessimistic insert and update if the buffer
pool is exhausted by locks
which can contain the new flag DICT_TF_COMPACT. Change dict_mem_table_create

Change some places to explicitly assume that system tables do not use the
compact page format.
