A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

If the having condition contains a constant conjunct that is always false
an empty result set is returned after the optimization phase.

"Impossible HAVING" in the last column.

The patch contains of the following:
- make Instance Manager, running in the daemon mode, dump
the pid of angel-process in the special file;
- default value of angel-pid-file-name is 'mysqlmanager.angel.pid';
- if ordinary (IM) pid-file-name is specified in the configuration,
angel-pid-file-name is updated according to the following
rule: extension of the basename of pid-file-name is replaced by
'.angel.pid.
For example:
- pid-file-name: /tmp/im.pid
=> angel-pid-file-name: /tmp/im.angel.pid
- pid-file-name: /tmp/im.txt
=> angel-pid-file-name: /tmp/im.angel.pid
- pid-file-name: /tmp/5.0/im
=> angel-pid-file-name: /tmp/5.0/im.angel.pid
- add support for configuration option to customize angel
pid file name;
- fix test suite to use angel pid to kill Instance Manager
by all means if something went wrong.
Background
----------
The problem is that on some OSes (FreeBSD for one) Instance
Manager does not get SIGTERM, so can not shutdown gracefully.
Test suite wasn't able to cope with it, so this leads to the
mess in test results.
The problem should be split into two:
- fix signal handling;
- fix test suite.
This patch fixes test suite so that it will be able to kill
uncooperative Instance Manager. In order to achieve this,
test suite needs to know PID of IM Angel process.
mysql-test/lib/mtr_process.pl:
Added a function to send a signal to a process.
mysql-test/mysql-test-run.pl:
Changed procedure of stopping Instance Manager.
1. Try to stop IM normally (by sending SIGTERM);
2. If one of IM-related processes is still alive,
kill them all by SIGKILL and complain in the log.

hog memory".
During each invocation of stored function or trigger some objects which
lifetime is one function call (e.g. sp_rcontext) were allocated on
arena/memroot of calling statement. This led to consumption of fixed amount
of memory for each function/trigger invocation and so statements which
involve lot of them were hogging memory. This in its return led to OOM
crashes or freezes.
This fix introduces new memroot and arena for objects which lifetime is
whole duration of function call. So all memory consumed by such objects
is freed at the end of function call.
sql/sp_head.cc:
sp_head::execute_function():
Introduced new memroot and arena for objects which lifetime is whole
duration of function call (e.g. sp_rcontext, sp_cursor). We can't
use caller's arena/memroot for those objects because in this case
some fixed amount of memory will be consumed for each function/trigger
invocation and so statements which involve lot of them will hog memory.
Got rid of param_values array to avoid excessive juggling with arenas.
The bug was as follows: When merge_key_fields() encounters "t.key=X OR t.key=Y" it will
try to join them into ref_or_null access via "t.key=X OR NULL". In order to make this
inference it checks if Y<=>NULL, ignoring the fact that value of Y may be not yet known.
The fix is that the check if Y<=>NULL is made only if value of Y is known (i.e. it is a
constant).
TODO: When merging to 5.0, replace used_tables() with const_item() everywhere in merge_key_fields().

The reason of the bug is in that `get_var_with_binlog' performs missed
assingment of
the variables as side-effect. Doing that it eventually calls
`free_underlaid_joins' to pass as an argument `thd->lex->select_lex' of the lex
which belongs to the user query, not
to one which is emulated i.e SET @var1:=NULL.
`get_var_with_binlog' is refined to supply a temporary lex to sql_set_variables's stack.
