After trying multiple inheritance (to messy and hard make it work) and
sublassing jump_if_not (worked, but ugly), decided to on this solution
instead:
Inserting an abstract sp_instr_opt_meta class as parent for all instructions
with destinations makes it possible to handle a continuation pointer for
sp_instr_set_case_expr too.
Note: No special test case; the fix is captured by the changed behaviour of
bug14643_2, and bug14498_4 (formerly disabled), in sp.test.
Since replication rules execute after `mysql_multi_update_prepare' returns we
delay to `break' in case this functions returns non-zero (some tables are not found)
for to examine if there is an ignore rule for a not-found table. By doing that
it is guaranteed do/ignore replication rules logically preceed opening table routine.
There are two main idea of this fix:
- introduce a common function for server and client to split user value
(<user name>@<host name>) into user name and host name parts;
- dump DEFINER clause in correct format in mysqldump.
- Fixed tests
- Optimized new code
- Fixed some unlikely core dumps
- Better bug fixes for:
- #14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
- #14850 (ERROR 1062 when a quering a view using a Group By on a column that can be null
Problem #1: INSERT...SELECT, Version for 5.0.
Extended the unique table check by a check of lock data.
Merge sub-tables cannot be detected by doing name checks only.
Problem #1: INSERT...SELECT, Version for 4.1.
INSERT ... SELECT with the same table on both sides (hidden
below a MERGE table) does now work by buffering the select result.
The duplicate detection works now after open_and_lock_tables()
on the locks.
I did not find a test case that failed without the change in
sql_update.cc. I made the change anyway as it should in theory
fix a possible MERGE table problem with multi-table update.
according to the standard.
The idea is to use Field-classes to implement stored routines
variables. Also, we should provide facade to Item-hierarchy
by Item_field class (it is necessary, since SRVs take part
in expressions).
The patch fixes the following bugs:
- BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data
type matching;
- BUG#8768: Functions: For any unsigned data type, -ve values can be passed
and returned;
- BUG#8769: Functions: For Int datatypes, out of range values can be passed
and returned;
- BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use
DECIMAL datatype;
- BUG#9572: Stored procedures: variable type declarations ignored;
- BUG#12903: upper function does not work inside a function;
- BUG#13705: parameters to stored procedures are not verified;
- BUG#13808: ENUM type stored procedure parameter accepts non-enumerated
data;
- BUG#13909: Varchar Stored Procedure Parameter always BINARY string (ignores
CHARACTER SET);
- BUG#14161: Stored procedure cannot retrieve bigint unsigned;
- BUG#14188: BINARY variables have no 0x00 padding;
- BUG#15148: Stored procedure variables accept non-scalar values;

Post-review version. Some minor review fixes, but also changed the way
some errors are handled: Don't return specific parse errors; instead
always use the more general "table corrupt" error (amended accordingly).
