symptom). sys_var::check_set() was wrong. mysqlbinlog makes use of such SET SQL_MODE=N
(where N is interpreted like if SQL_MODE was a field of type SET), so
this bug affected recovery from binlogs if the server was running with certain SQL_MODE values,
for example the default values on Windows (STRICT_TRANS_TABLES); to work around this bug people
had to edit mysqlbinlog's output.
mysql-test/r/sql_mode.result:
result update
mysql-test/t/sql_mode.test:
test for various numeric SQL_MODE values
sql/set_var.cc:
For a set, it does not make sense to test if the supplied argument exceeds the number of elements in the set
(such test would make sense for an enum), but rather to check if it exceeds 2^this (to verify
that only reasonable bits are set).
if the function, invoked in a non-binlogged caller (e.g. SELECT, DO), failed half-way on the master,
slave would stop and complain that error code between him and master mismatch.
To solve this, when a stored function is invoked in a non-binlogged caller (e.g. SELECT, DO), we binlog the function
call as SELECT instead of as DO (see revision comment of sp_head.cc for more).
And: minor wording change in the help text.
This cset will cause conflicts in 5.1, I'll merge.

cleanup at the end.
sql/mysqld.cc:
function -> stored function (change suggested by Paul)
sql/sp_head.cc:
When a function updates data and is called from a non-binlogged statement (SELECT, DO), we binlog it
as SELECT myfunc(), and not DO myfunc() like before.
problem was: when a connection disconnects having an open transaction affecting MyISAM and InnoDB, the ROLLBACK event stored in the binary log
contained a non-zero error code (1053 because of the disconnection), so when slave applied the transaction, slave complained that its ROLLBACK succeeded
(error_code=0) while master's had 1053, so slave stopped. But internally generated binlog events such as this ROLLBACK
should always have 0 as error code, as is true in 4.1 and was accidentally broken in 5.0,
so that there is no false alarm.

trigger starts trigger".
In short, the deadlock/crash happened when execution of statement, which used
stored functions or activated triggers, coincided with alteration of the
tables used by these functions or triggers (in highly concurrent environment).
Bug was caused by the incorrect handling of tables from prelocked set in
open_tables() functions in situations when refresh happened. This fix replaces
old smart but not very robust way of handling tables after refresh (which was
closing only old tables), with new one which simply closes all tables opened so
far and restarts open_tables().
Also fixed handling of temporary tables in close_tables_for_reopen().
No test case present since bug manifests itself only in concurrent environment.
sql/mysql_priv.h:
In order to handle correctly case when table list completely consists from tables
from prelocked set close_tables_for_reopen() have to accept table list as in/out
parameter.
sql/sql_base.cc:
open_tables():
Removed part of comment which was out of date.
Changed handling of case when refresh happens during opening of tables, now
instead of having code which decides for each table if it should be closed
we simply close all tables. Old code also incorrectly handled tables from
prelocked set in this situation which resulted in bug #16593 "Deadlock or
crash in stress test for case where triggers starting trigger".
close_tables_for_reopen():
Now we correctly handle the case when table list completely consists from
tables from prelocked set. Also now we simply close all tables instead
leaving temporary tables non-closed (such approach allows easily handle
correctly tables from prelocked set).
sql/sql_prepare.cc:
In order to handle correctly case when table list completely consists from tables
from prelocked set close_tables_for_reopen() have to accept table list as in/out

- Retry the ping if reconnect is turned on and the error was CR_SERVER_LOST
libmysql/libmysql.c:
Send a new ping if first ping fails with CR_SERVER_LOST and reconnect is turned on
- Detect that connection to server has been broken in "net_clear". Since
net_clear is always called before we send command to server, we can be sure
that server has not received the command.

Decrease sleep times
sql/net_serv.cc:
Make "net_clear" detect if connection with server has been broken by
performing a select. If the select returns that there are data to read but
no data can be read, that means the connection is broken. Signal disconnected
to "write" functions by setting error to 2.

If item->cached_table is set, find_field_in_tables() returns found field
even if it doesn't belong to current select. Because Item_field::fix_fields
doesn't expect such behaviour, reported bug occurs.
Item_field::fix_fields() was modifed to detect when find_field_in_tables()
can return field from outer select and process such fields accordingly.
In order to ease this code which was searching and processing outed fields was
moved into separate function called Item_field::fix_outer_field().
sql/item_subselect.h:
Fixed bug #15706: find_field_in_tables() returns field from outer select
Item_field::fix_outer_field() was marked as friend to Item_subselect class.
sql/item.h:
Fixed bug #15706: find_field_in_tables() returns field from outer select
fix_outer_field() function is added to the Item_field class.
sql/item.cc:
Fixed bug #15706: find_field_in_tables() returns field from outer select
Item_ref::fix_fields() and Item_field::fix_fields() were modifed to detect when
find_field_in_tables() can return field from outer select and process such
fields accordingly.
In order to ease this, code Item_field::fix_fields() which was searching and
processing outer fields was moved into separate function called
Item_field::fix_outer_field().
To the Item_field::fix_field() added a loop for finding context for found field.
