The general log write function (general_log_print) uses printf style
arguments which need to be pre-processed, meaning that the all arguments
are copied to a single buffer and the problem is that the buffer size is
constant (1022 characters) but queries can be much larger then this.
The solution is to introduce a new log write function that accepts a
buffer and it's length as arguments. The function is to be used when
a formatted output is not required, which is the case for almost all
query write-to-log calls.
This is a incompatible change with respect to the log format of prepared
statements.

mysql-test/t/log_tables.test:
Add test case for Bug#21557
sql/log.cc:
Introduce the logger function general_log_write which is similar to
general_log_print but accepts a single buffer and the buffer length.
The function doesn't perform any formatting and sends the buffer
directly to the underlying log handlers.
sql/log.h:
Introduce the logger function general_log_write.
sql/log_event.cc:
Pass the query buffer directly to the logger function, formatting
is not required on this case.
sql/mysql_priv.h:
Prototype for the logger function general_log_write.
sql/sp_head.cc:
Pass the query buffer directly to the logger function, formatting
is not required on this case.
sql/sql_parse.cc:
Pass the buffer directly to the logger function when formatting
is not required.
sql/sql_prepare.cc:
Don't log the statement id, it avoids making a extra copy of the query
and the query is not truncated anymore if it exceeds the limit.
The server crashed when a thread was killed while locking the
general_log table at statement begin.
The general_log table is handled like a performance schema table.
The state of open tables is saved and cleared so that this table
seems to be the only open one. Then this table is opened and locked.
After writing, the table is closed and the open table state is
restored. Before restoring, however, it is asserted that there is
no current table open.
After locking the table, mysql_lock_tables() checks if the thread
was killed in between. If so, it unlocks the table and returns an
error. open_ltable() just returns with the error and leaves closing
of the table to close_thread_tables(), which is called at
statement end.
open_performance_schema_table() did not take this into account.
It assumed that a failed open_ltable() would not leave an open
table behind.
Fixed by closing thread tables after open_ltable() and before
restore_backup_open_tables_state() if the thread was killed.
No test case. It requires correctly timed parallel execution.
Since this bug was detected by the test suite, it seems
dispensable to add another test.

No warning was generated when a TIMESTAMP with a non-zero time part
was converted to a DATE value. This caused index lookup to assume
that this is a valid conversion and was returning rows that match
a comparison between a TIMESTAMP value and a DATE keypart.
Fixed by generating a warning on such a truncation.

Previously, UDF *_init functions were passed constant strings with erroneous lengths. The length came from the containing variable's size, not the length of the value itself.

The problem was that the RETURNS column in the mysql.proc was of

during writing into mysql.proc.

The problem is that currently there is no way to test the behavior
of the mysql_change_user() function using the mysqltest suite because

The root cause of the issue was that the CREATE FUNCTION grammar,
for User Defined Functions, was using the sp_name rule.
The sp_name rule is intended for fully qualified stored procedure names,
like either ident.ident, or just ident but with a default database
implicitly selected.
A UDF does not have a fully qualified name, only a name (ident), and should
not use the sp_name grammar fragment during parsing.
The fix is to re-organize the CREATE FUNCTION grammar, to better separate:
- creating UDF (no definer, can have AGGREGATE, simple ident)
- creating Stored Functions (definer, no AGGREGATE, fully qualified name)
With the test case provided, another issue was exposed which is also fixed:
the DROP FUNCTION statement was using sp_name and also failing when no database
is implicitly selected, when droping UDF functions.
The fix is also to change the grammar so that DROP FUNCTION works with
both the ident.ident syntax (to drop a stored function), or just the ident
syntax (to drop either a UDF or a Stored Function, in the current database)
