The idea of the patch is to separate statement processing logic, such as parsing, validation of the parsed tree, execution and cleanup, from global query processing logic, such as logging, resetting priorities of a thread, resetting stored procedure cache, resetting thread count of errors and warnings. This makes PREPARE and EXECUTE behave similarly to the rest of SQL statements and allows their use in stored procedures. This patch contains a change in behaviour: until recently for each SQL prepared statement command, 2 queries were written to the general log, e.g. [Query] prepare stmt from @stmt_text; [Prepare] select * from t1 <-- contents of @stmt_text The chagne was necessary to prevent [Prepare] commands from being written to the general log when executing a stored procedure with Dynamic SQL. We should consider whether the old behavior is preferrable and probably restore it. This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs in Dynamic SQL reported before it was disabled).
