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.
mysql-test/r/mysqldump.result:
Updated result file.
mysql-test/r/sp.result:
Updated result file.
mysql-test/t/sp.test:
Provided test cases for BUG#16211, BUG#16676.
sql/mysql_priv.h:
Added two convenient functions for work with databases.
sql/sp.cc:
1. Add CHARSET-clause to CREATE-statement if it has been explicitly specified.
2. Polishing -- provided some comments.
sql/sp_head.cc:
Use database charset as default charset of sp-variable.
sql/sp_head.h:
Move init_sp_name() out of init_strings().
sql/sql_db.cc:
Two new functions created:
- load_db_opt_by_name();
- check_db_dir_existence();
sql/sql_show.cc:
Eliminate duplicated code by using
check_db_dir_existence() and load_db_opt_by_name()
sql/sql_table.cc:
Eliminate duplicated code by using
check_db_dir_existence() and load_db_opt_by_name()
sql/sql_yacc.yy:
Call sp_head::init_sp_name() to initialize stored routine name.

The fix is: if user has privileges to view fields and user has any
(insert,select,delete,update) privileges on underlying view
then 'show fields' and select from I_S.COLUMNS table are sucsessful.

mysql-test/t/information_schema_db.test:
Bug#20543 select on information_schema strange warnings, view, different schemas/users
test case
sql/sql_acl.cc:
Bug#20543 select on information_schema strange warnings, view, different schemas/users
checked that user has privileges on underlying view and if it's true
set allowed_show to true for top view.
sql/sql_show.cc:
Bug#20543 select on information_schema strange warnings, view, different schemas/users
removed unnecessary rights check.'tables->allowed_show' check is used instead
sql/sql_view.cc:
Bug#20543 select on information_schema strange warnings, view, different schemas/users
skip the check of SHOW_VIEW_ACL privilege on underlying view. It is done later during
execution of find_field_in_table_ref function.
sql/table.h:
Bug#20543 select on information_schema strange warnings, view, different schemas/users
'allowed_show' is set during rights check for view. If true then user has privileges
for 'show create view', etc
The fix is: if user has privileges to view fields and user has any
(insert,select,delete,update) privileges on underlying view
then 'show fields' and select from I_S.COLUMNS table are sucsessful.
a non-correlated single-row subquery over information schema.
The function get_all_tables filling all information schema
tables reset lex->sql_command to SQLCOM_SHOW_FIELDS. After
this the function could evaluate partial conditions related to
some columns. If these conditions contained a subquery over
information schema it led to a wrong evaluation and a wrong
result set.
This bug was already fixed in 5.1.
This patch follows the way how it was done in 5.1 where
the value of lex->sql_command is set to SQLCOM_SHOW_FIELDS
in get_all_tables only for the calls of the function
open_normal_and_derived_tables and is restored after these
calls.
mysql-test/r/information_schema.result:

subqueries on information schema that use MIN/MAX aggregation.
Execution of some correlated subqueries may set the value
of null_row to 1 for tables used in the subquery.
If the the subquery is on information schema it causes
rejection of any row for the following executions of
the subquery in the case when an optimization filtering
by some condition is applied.
The fix restores the value of the null_row flag for
each execution of a subquery on information schema.

After view onening real view db name and table name are placed

Cut number 6. Move code from sql_show.cc to event_db_repository.cc
that more belongs to the latter.
sql/event_db_repository.cc:
move code that works with mysql.event from sql_show.cc to
event_db_repository.cc . Route through Event_db_repository's interface
which is proxied by class Events. The code relies on a function from
sql_show.cc which does the actual storage in the schema table. I think
it's better to leave the function there because the structure of
I_S.EVENTS is defined in sql_show.cc
sql/event_db_repository.h:
I_S / SHOW EVENTS handling hooks
sql/event_scheduler.cc:
use the pointer to db_repository which Event_scheduler already has
sql/events.cc:

sql/events.h:
callback for I_S (sql_show.cc)
sql/sql_show.cc:
move code that belongs more to Event_db_repository than to here.
Use a callback of class Events. Only 1 function is left here, because
it copies data into the actual rows of I_S.EVENTS and belongs to this file.
sql/sql_show.h:
export this function will be called from event_db_repository.cc
5th cut, moved DB related code to Event_db_repository and
updated accordingly the remanining code.
Moved change/restore_security_context() to class THD
Removed events_priv.h
Next step is to reorganize create/update_event() and parsing for them.
But probably some other refactoring could be done in the meanwhile.
