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).
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it
- For a busy system this change will give you:
- Less memory usage for table object
- Faster opening of tables (if it's has been in use or is in table definition cache)
- Allow you to cache many table definitions objects
- Faster drop of table
Bad examples of usage of a string with its length fixed.
The incorrect length in the trigger file configuration descriptor
fixed (BUG#14090).
A hook for unknown keys added to the parser to support old .TRG files.
ps_6bdb (this one fails circa once over 4 runs). After the merge: the same PLUS mysql_client_test&sp (due to problem in fix of BUG#14845 which has also
been noticed in 5.0 too and Konstantin is looking at it) PLUS mysqlcheck (just consequence of mysql_client_test).
And a replication bugfix (thd->spcont must be taken into account when calling tables_ok(), as in 5.0,
and so some brackets were missing which changed one test).
Pekka will look at the NDB code where I just used "ul": ndb_charset test, and storage/ndb/src/kernel/vm/SimulatedBlock.cpp
and storage/ndb/src/kernel/blocks/dbtup/DbtupRoutines.cpp (SimulatedBlock.hpp automerged);
please also check storage/ndb/src/ndbapi/NdbRecAttr.cpp. Petr please check ha_tina.cc.
handling of savepoints in stored routines.
Fixed ha_rollback_to_savepoint()/ha_savepoint()/ha_release_savepoint()
functions to properly handle savepoints inside of stored functions and
triggers.
Also now when we invoke stored function or trigger we create new savepoint
level. We destroy it at the end of function/trigger execution and return back
to old savepoint level.

(2nd try; Pekka kindly accepted to fix storage/ndb/src/kernel/blocks/dbtup/DbtupRoutines.cpp
and storage/ndb/src/kernel/vm/SimulatedBlock.cpp after I push).
