This patch fixes the following bugs:
- Bug#5889: Exit handler for a warning doesn't hide the warning in
trigger
- Bug#9857: Stored procedures: handler for sqlwarning ignored
- Bug#23032: Handlers declared in a SP do not handle warnings generated
in sub-SP
- Bug#36185: Incorrect precedence for warning and exception handlers
The problem was in the way warnings/errors during stored routine execution
were handled. Prior to this patch the logic was as follows:
- when a warning/an error happens: if we're executing a stored routine,
and there is a handler for that warning/error, remember the handler,
ignore the warning/error and continue execution.
- after a stored routine instruction is executed: check for a remembered
handler and activate one (if any).
This logic caused several problems:
- if one instruction generates several warnings (errors) it's impossible
to choose the right handler -- a handler for the first generated
condition was chosen and remembered for activation.
- mess with handling conditions in scopes different from the current one.
- not putting generated warnings/errors into Warning Info (Diagnostic
Area) is against The Standard.
The patch changes the logic as follows:
- Diagnostic Area is cleared on the beginning of each statement that
either is able to generate warnings, or is able to work with tables.
- at the end of a stored routine instruction, Diagnostic Area is left
intact.
- Diagnostic Area is checked after each stored routine instruction. If
an instruction generates several condition, it's now possible to take a
look at all of them and determine an appropriate handler.
mysql-test/r/signal.result:
Update result file:
1. handled conditions are not cleared any more;
2. reflect changes in signal.test
mysql-test/r/signal_demo3.result:
Update result file: handled conditions are not cleared any more.
Due to playing with max_error_count, resulting warning lists
have changed.
mysql-test/r/sp-big.result:
Update result file: handled conditions are not cleared any more.
mysql-test/r/sp-bugs.result:
Update result file: handled conditions are not cleared any more.
mysql-test/r/sp-code.result:
Update result file:
1. handled conditions are not cleared any more.
2. add result for a new test case in sp-code.test.
mysql-test/r/sp-error.result:
Update result file:
1. handled conditions are not cleared any more.
2. add result for a new test case in sp-error.test.

mysql-test/t/signal.test:
Make a test case more readable in the result file.
mysql-test/t/sp-code.test:
Add a test case for Bug#23032 checking that
No Data takes precedence on Warning.
mysql-test/t/sp-error.test:
Adding test cases for:
- Bug#23032
- Bug#36185
- Bug#5889
- Bug#9857
mysql-test/t/sp.test:
Fixing test case to reflect behavioral changes made by the patch.
sql/sp_head.cc:
Reset the per-statement warning count before executing
a stored procedure instruction.
Move to a separate function code which checks the
completion status of the executed statement and searches
for a handler.
Remove redundant code now that search for a handler is
done after execution, errors are always pushed.
sql/sp_pcontext.h:
Remove unused code.
sql/sp_rcontext.cc:
- Polish sp_rcontext::find_handler(): use sp_rcontext::m_hfound instead
of an extra local variable;
- Remove sp_rcontext::handle_condition();
- Introduce sp_rcontext::activate_handler(), which prepares
previously found handler for execution.
- Move sp_rcontext::enter_handler() code into activate_handler(),
because enter_handler() is used only from there;
- Cleanups;
- Introduce DBUG_EXECUTE_IF() for a test case in sp-code.test
sql/sp_rcontext.h:
- Remove unused code
- Cleanups
sql/sql_class.cc:
Merge THD::raise_condition_no_handler() into THD::raise_condition().
After the patch raise_condition_no_handler() was called
in raise_condition() only.
sql/sql_class.h:
Remove raise_condition_no_handler().
sql/sql_error.cc:
Remove Warning_info::reserve_space() -- handled conditions are not
cleared any more, so there is no need for RESIGNAL to re-push them.
sql/sql_error.h:
Remove Warning_info::reserve_space().
sql/sql_signal.cc:
Handled conditions are not cleared any more,
so there is no need for RESIGNAL to re-push them.
