The bug report revealed two problems related to min/max optimization:
1. If the length of a constant key used in a SARGable condition for
for the MIN/MAX fields is greater than the length of the field an
unwanted warning on key truncation is issued;
2. If MIN/MAX optimization is applied to a partial index, like INDEX(b(4))
than can lead to returning a wrong result set.
mysql-test/r/func_group.result:

mysql-test/t/func_group.test:

sql/opt_sum.cc:
Fixed bug #18206.
Suppressed the warning about data truncation when store_val_in_field
was used to store keys for the field used in MIN/MAX optimization.
Blocked MIN/MAX optimization for partial keys, such as in INDEX(b(4)).
sql/sql_select.cc:
Fixed bug #18206.
Added a parameter for the function store_val_in_field allowing to
control setting warnings about data truncation in the function.

the correct access method.

The IN() function uses agg_cmp_type() to aggregate all types of its arguments
to find out some common type for comparisons. In this particular case the
char() and the int was aggregated to double because char() can contain values
like '1.5'. But all strings which do not start from a digit are converted to
0. thus 'a' and 'z' become equal.
This behaviour is reasonable when all function arguments are constants. But
when there is a field or an expression this can lead to false comparisons. In
this case it makes more sense to coerce constants to the type of the field
argument.
The agg_cmp_type() function now aggregates types of constant and non-constant
items separately. If some non-constant items will be found then their
aggregated type will be returned. Thus after the aggregation constants will be
coerced to the aggregated type.
mysql-test/t/func_in.test:
Added test case for bug#18360: Incorrect type coercion in IN() results in false comparison.
mysql-test/r/func_in.result:
Added test case for bug#18360: Incorrect type coercion in IN() results in false comparison.
sql/item_cmpfunc.cc:
Fixed bug#18360: Incorrect type coercion in IN() results in false comparison.
The agg_cmp_type() function now aggregates types of constant and non-constant
items separately. If some non-constant items will be found then their
aggregated type will be returned. Thus after the aggregation constants will
be coerced to the aggregated type.
In multi-table delete a table for delete can't be used for selecting in
subselects. Appropriate error was raised but wasn't checked which leads to a
crash at the execution phase.
The mysql_execute_command() now checks for errors before executing select
for multi-delete.

- A segfault occured when the function 'kill_server' called
'my_sigset' with signal number 0. 'my_sigset' is a macro which
uses 'sigaction' to install the signal handler with an invalid
signal number will on most platforms return EINVAL but yields
a segfauilt on IRIX 6.5
- The server crash was detected by mysqld_safe and it was restarted although
a shutdown was requested.
- Semantics of kill_server(0) is not known, leaving it intact

fixing encoding example because of table names can not be in koi8r
on some platforms.
mysql-test/t/rpl_temporary.test:
koi8r encoding to name tables is changed for latin1 for the former does not work
on some platforms.
The effect of the test remains: a test table is named to have multibyte utf8 representation,
which is the essence of the bug.

A pattern to generate binlog for DROPped temp table in close_temporary_tables
was buggy: could not deal with a grave-accent-in-name table.
The fix exploits `append_identifier()' for quoting and duplicating accents.

I hope to become much simplier than previously. No-binlog branch is separated completely the
rest that adopts String's methods.

Binlog lacks encoding info about DROPped temporary table.
Idea of the fix is to switch temporary to system_charset_info when a temporary table
is DROPped for binlog. Since that is the server, that automatically, but not the client, who generates the query
the binlog should be updated on the server's encoding for the coming DROP.
The `write_binlog_with_system_charset()' is introduced to replace similar problematic places in the code.
