Also change

to

Provided that innobase_buffer_pool_size is always 64bits these statements
are equivalent if ulint is 64 bit (well it will screw up if
innobase_buffer_pool_size is negative). And if ulint is 32 bit the later
variant gives a little more chance that the value will fit.

MySQL error code requested to properly report the error condition back
to the client has not yet materialized. Currently we have #ifdef'd the
error code translation in ha_innodb.cc. This will have to be changed
as and when MySQl add the new requested code or an equivalent code
that we can then use.

Given the above, currently we will get the old behaviour, not the "fixed"
and intended behaviour.

innodb_commit_concurrency was implemented.

MySQL calls external_lock at the beginning and end of a statement
when it is not calling start_stmt or commit or rollback.  Thus,
statement boundaries can be (and are already) detected without
monitoring thd->query_id.

The function innobase_commit() seemingly lacks the call to
innobase_release_stat_resources(), which should be called at
the end of every SQL statement.  The call was replaced by
equivalent statements by Vadim Tkachenko when he implemented
innodb_commit_concurrency in MySQL 5.0:
