Fix for BUG#16676: Database CHARSET not used for stored procedures
The problem in BUG#16211 is that CHARSET-clause of the return type for
stored functions is just ignored.
The problem in BUG#16676 is that if character set is not explicitly
specified for sp-variable, the server character set is used instead
of the database one.
The fix has two parts:
- always store CHARSET-clause of the return type along with the
type definition in mysql.proc.returns column. "Always" means that
CHARSET-clause is appended even if it has not been explicitly
specified in CREATE FUNCTION statement (this affects BUG#16211 only).
Storing CHARSET-clause if it is not specified is essential to avoid
changing character set if the database character set is altered in
the future.
NOTE: this change is not backward compatible with the previous releases.
- use database default character set if CHARSET-clause is not explicitly
specified (this affects both BUG#16211 and BUG#16676).
NOTE: this also breaks backward compatibility.

when calling a SP from C API"
The bug was caused by lack of checks for misuse in mysql_real_query.
A stored procedure always returns at least one result, which is the
status of execution of the procedure itself.
This result, or so-called OK packet, is similar to a result
returned by INSERT/UPDATE/CREATE operations: it contains the overall
status of execution, the number of affected rows and the number of
warnings. The client test program attached to the bug did not read this
result and ivnoked the next query. In turn, libmysql had no check for
such scenario and mysql_real_query was simply trying to send that query
without reading the pending response, thus messing up the communication
protocol.
The fix is to return an error from mysql_real_query when it's called
prior to retrieval of all pending results.
client/mysqlbinlog.cc:
net_safe_read -> cli_safe_read
include/mysql.h:
Remove a private function from the public header.
include/mysql_com.h:
Remove a define that is never used.
include/sql_common.h:
Add a declaration for cli_safe_read - a function that reads one packet
from the server.
libmysql/libmysql.c:
net_safe_read -> cli_safe_read
Return CR_COMMANDS_OUT_OF_SYNC on attempt to execute a statement
using a connection which has pending result sets.
sql-common/client.c:
Actual fix for Bug#15752: if the server has pending result sets for
the client, return CR_COMMANDS_OUT_OF_SYNC on attempt to execute
another query. Similarly to the behaviour of mysql_use_result(),
multiple result sets block the connection and must be fetched
before it can be used for another query.
This uncovered an error in the protocol: the server doesn't drop
SERVER_MORE_RESULTS_EXISTS status flag upon an error, so in case of
a multi-query like SELECT 1; SELECT syntax_error; SELECT 2;
the client has no way to know that the server won't ever come to
execution of the third query and won't return any result sets for it.
For now, fix it in cli_safe_read, as a proper fix requires extension
of the client-server protocol.
sql/protocol.cc:
Remove a name that is never used.
sql/slave.cc:
net_safe_read -> cli_safe_read
tests/mysql_client_test.c:
Make 'query' a local variable to avoid name clash.
Add a test case for Bug#15752 "Lost connection to MySQL server when
calling an SP from C API"
Fix for the bug in mysql-test-run.pl which prevents other tests succeed
after IM-test failure.
The idea of the fix of BUG#20716 is to:
1. Check each SHOW INSTANCES statement, add necessary "sleep" instruction before;
2. Move all environment checkings into the one file and include it everywhere.

The statements in the file ensure that starting
conditions (environment) are as expected.
and Stored Procedure
The essence of the bug was that for every re-execution of stored
routine or prepared statement new items for character set conversions
were created, thus increasing the number of items and the time of their
processing, and creating memory leak.
No test case is provided since current test suite can't cover such type
of bugs.

Add result for bug#21013: Performance Degrades when importing data

context.
Routine arguments were evaluated in the security context of the routine
itself, not in the caller's context.
The bug is fixed the following way:
- Item_func_sp::find_and_check_access() has been split into two
functions: Item_func_sp::find_and_check_access() itself only
finds the function and check that the caller have EXECUTE privilege
on it. New function set_routine_security_ctx() changes security
context for SUID routines and checks that definer have EXECUTE
privilege too.
- new function sp_head::execute_trigger() is called from
Table_triggers_list::process_triggers() instead of
sp_head::execute_function(), and is effectively just as the
sp_head::execute_function() is, with all non-trigger related code
removed, and added trigger-specific security context switch.
- call to Item_func_sp::find_and_check_access() stays outside
of sp_head::execute_function(), and there is a code in
sql_parse.cc before the call to sp_head::execute_procedure() that
checks that the caller have EXECUTE privilege, but both
sp_head::execute_function() and sp_head::execute_procedure() call
set_routine_security_ctx() after evaluating their parameters,
and restore the context after the body is executed.

Add test case for bug#18630: Arguments of suid routine calculated

Add declaration for sp_head::execute_trigger() and
set_routine_security_ctx().
sql/sql_parse.cc:
Do not change security context before executing the procedure, as it
will be changed after argument evaluation.
sql/sql_trigger.cc:
Call new sp_head::execute_trigger() instead of
sp_head::execute_function(), which is responsible to switch
security context.

closing temp tables through end_thread
had a flaw in binlog-off branch of close_temporary_tables where
next table to close was reset via table->next
for (table= thd->temporary_tables; table; table= table->next)
which was wrong since the current table instance got destoyed at
close_temporary(table, 1);
The fix adapts binlog-on branch method to engage the loop's internal 'next' variable which holds table->next prior table's destoying.
sql/sql_base.cc:
no-binlog branch is fixed: scanning across temporary_tables must be careful to save next table since the current is being destroyed inside of close_temporary.
binlog-is-open case is ok.
