When resolving unqualified name references MySQL was not
checking what is the item type for the reference. Thus
e.g a string literal item that has by convention a name
equal to its string value will also work as a reference to
a SELECT list item or a table field.
Fixed by allowing only Item_ref or Item_field to referenced by
(unqualified) name.

The mysql_alter_table() was able to rename only a table.

to the new function called do_rename().

Bug #21785 "Server crashes after rename of the log table" and
Bug #21966 "Strange warnings on create like/repair of the log
tables"
According to the patch, from now on, one should use RENAME to
perform a log table rotation (this should also be reflected in
the manual).
Here is a sample:
use mysql;
CREATE TABLE IF NOT EXISTS general_log2 LIKE general_log;
RENAME TABLE general_log TO general_log_backup, general_log2 TO general_log;
The rules for Rename of the log tables are following:
IF 1. Log tables are enabled
AND 2. Rename operates on the log table and nothing is being
renamed to the log table.
DO 3. Throw an error message.
ELSE 4. Perform rename.
The very RENAME query will go the the old (backup) table. This is
consistent with the behavoiur we have with binlog ROTATE LOGS
statement.
Other problems, which are solved by the patch are:
1) Now REPAIR of the log table is exclusive operation (as it should be), this
also eliminates lock-related warnings. and
2) CREATE LIKE TABLE now usese usual read lock on the source table rather
then name lock, which is too restrictive. This way we get rid of another
log table-related warning, which occured because of the above fact
(as a side-effect, name lock resulted in a warning).
mysql-test/r/log_tables.result:
update result file
mysql-test/t/log_tables.test:
Add tests for the bugs
sql/handler.cc:
update comment
sql/handler.h:
update function to reflect changes in log tables
locking logic.
sql/lock.cc:
Now we allow locking of the log tables for "privileged" threads
Privileged thread must explicitly close and lock log tables. This
is required for admin operations such as REPAIR.
sql/log.cc:
Changes to the file:
1) Add checks for table schema. It's more important now,
as we allow rename of the log tables. Since we should
check for schema when writing to a log table.
E.g. if one created a table with one-only comlumn and
renamed it to general_log, the server should cope with
it.
2) refactor LOGGER::flush(), so that we can now use the same
machinery as we use in FLUSH LOGS in other statements:
whenever we have to perform a serious operation on the log
tables, we have to
(a) lock logger, which blocks other concurrent statements (such
as selects) (b) close logs. Then perform an
exclusive operation, c) reenable logs and d) unlock logger.
3) Add a function to check if a given table is a log table.
4) Add support for "privileged" thread
5) merge is_[general/slow]_log_table_enabled() into one function.
6) Add new function: reopen _log_tables, which reopens the tables,
which were enabled (after temporary close, required for admin
operation)
sql/log.h:
1) add a new call close_n_lock_tables(). Now we use it instead of
LOGGER::flush() in FLUSH LOGS implementation.
2) add a prototype for the function to check if a given
table is a log table;
3) add privileged table flag to table logger
4) merge is_[general/slow]_log_table_enabled()
into one function.
sql/mysql_priv.h:
move log table defines to log.h
sql/sql_delete.cc:
use new function check_if_log_table() instead of direct strcmp
sql/sql_rename.cc:
Traverse the list of tables in mysql_rename_tables
to make sure that log tables are processed correctly
(that is, according to the rules specified in the
main CS comment)
sql/sql_table.cc:
1) mysql_admin_table() should disable logs if it performs
exclusive admin operation on a log table. This way we
also eliminate warning on REPAIR of the log table.
2) mysql_create_like_table should read-lock the source table
instead getting name lock on it. Name lock is too restrictive
in this case.
sql/share/errmsg.txt:
Add a new error message for rename of the log tables
sql/table.cc:
use new function instead of direct strcmp.
change my_strcasecmp() -> strcmp(), when

should fail to create
The problem was that this type of errors was checked during view
creation, which doesn't happen when CREATE VIEW is a statement of
a created stored routine.
The solution is to perform the checks at parse time. The idea of the
fix is that the parser checks if a construction just parsed is allowed
in current circumstances by testing certain flags, and this flags are
reset for VIEWs.
The side effect of this change is that if the user already have
such bogus routines, it will now get a error when trying to do
SHOW CREATE PROCEDURE proc;
(and some other) and when trying to execute such routine he will get
ERROR 1457 (HY000): Failed to load routine test.p5. The table mysql.proc is missing, corrupt, or contains bad data (internal code -6)
However there should be very few such users (if any), and they may
(and should) drop these bogus routines.
