Added checking of return value from malloc() in reg_init()
client/mysqltest.c:
Added comment
dbug/dbug.c:
Removed not needed test
mysys/charset.c:
Added checking of return value from my_once_alloc()
regex/reginit.c:
Abort if out of memory in reg_init() (unlikely)
sql/item_strfunc.cc:
Added comment
Otherwise, if the previous run ended with a crash, and the PID was 1234,
and you have rebooted the machine and the new PID is 99 then in the PID
file you will have 9934.
Note: users of mysqld_safe did not have the problem because this script
deletes the PID file before starting mysqld.
The constructor of Rotate_log_event used when we are rotating our binlog or
relay log, should not assume that there is a nonzero THD available.
For example, when we are reacting to SIGHUP, the THD is 0.
In fact we don't need to use the THD in this constructor;
we can do like for Stop_log_event, and use the minimal Log_event
constructor.
If we were allowed to put Unix-specific commands in the testsuite,
I'd add a test for this (<sigh>).
sql/log.cc:
A comment to warn that thd can be 0.
The part about LOG_EVENT_FORCED_ROTATE_F is just to avoid segfault;
this flag is already removed in 4.1 anyway.
sql/log_event.cc:
A comment.
sql/log_event.h:

This fixes BUG#2045

New formats added for 'week()' function and 'default_week_format' option(4 - 7).
Next formats is supported now:
*Value* *Meaning*
`0' Week starts on Sunday; First Sunday of the year starts week 1.
Week() returns 0-53.
`1' Week starts on Monday; Weeks numbered according to ISO 8601:1988.
Week() returns 0-53.
`2' Week starts on Sunday; First Sunday of the year starts week 1.
Week() returns 1-53.
`3' Week starts on Monday; Weeks numbered according to ISO 8601:1988.
Week() returns 1-53.
`4' Week starts on Sunday; Weeks numbered according to ISO 8601:1988.
Week() returns 0-53.
`5' Week starts on Monday; First Monday of the year starts week 1.
Week() returns 0-53.
`6' Week starts on Sunday; Weeks numbered according to ISO 8601:1988.
Week() returns 1-53.
`7' Week starts on Monday; First Monday of the year starts week 1.
Week() returns 1-53.

we change THD::system_thread from a 'bool' to a bitmap to be able to
distinguish between delayed-insert threads and slave threads.
- Fix for BUG#1701 "Update from multiple tables" (one line in sql_parse.cc,
plus a new test rpl_multi_update.test). That's just adding an initialization.
sql/repl_failsafe.cc:
comment to warn about this unused code
sql/slave.cc:
Now thd->system_thread is a bitmap, not a bool.
sql/sql_class.h:
'bool' for THD::system_thread is not accurate enough; sometimes we need
to distinguish between delayed-insert threads and slave threads;
so changing THD::system_thread to a bitmap (uint).
sql/sql_insert.cc:
thd.system_thread is now a bitmap
sql/sql_parse.cc:
We need to initialize thd->lex.select_lex.options in mysql_init_query();
it's already initialized in dispatch_command() but replication calls
mysql_parse() directly, thus bypassing dispatch_command().
Not initing it here leads to a query influencing the next query,
in the slave SQL thread.
The initialization in dispatch_command() must be kept as this
command uses the variable in tests, even when the command was not a
query (i.e. when mysql_init_query() was not called).

Stylistic clean-ups.
The problem was that when the slave SQL thread reads a hot relay log (hot = the one being written to by the
slave I/O thread), it must have the LOCK_log. It already took it for read_log_event(), but needs
it also for check_binlog_magic().
This should fix all recently reported failures of the rpl_max_relay_size test in 4.1 and 5.0
(though the bug exists since 4.0, it showed up first in 5.0).
sql/slave.cc:
Fix for BUG#2011 "rare race condition producing "binlog has bad magic number" error in slave".
The problem was that when the slave SQL thread reads a hot relay log (hot = the one being written to by the

about it". Now numbers representing illegal timestamps are
converted to 0 value if they are stored as timestamp or
datetime. This behaviour is consistent with manual and with
behaviour of string -> timestamp conversion.

Checks of month, day, hour, minute and second ranges were added

SQL_BIG_RESULT used':
- BIT_AND now returns BIGINT UNSIGNED
- in case there were no matching rows BIT_AND returns 18446744073709551615
(but not NULL), BIT_OR returns 0 (but not NULL). That's how Monty wants it
and how is described in our docs.
include/my_global.h:
Added definition for ULONGLONG_MAX.
This is also a check that ULL type specifier

BIT_AND and BIT_OR now are both BIGINT UNSIGNED
instead of Log_event::Log_event(THD*, ...) when the event is built in the master
to be written in the binlog.
Rand_log_event already used the good constructor, so there really is no reason
for Intvar_log_event to be an exception.
This fixes a test failure of last night (which appeared after I removed a useless
e.server_id=thd->server_id in log.cc; in fact this line was not useless because
it hid the bad constructor).
Replication tests pass, with Valgrind too.
sql/log_event.h:

which does e.server_id=thd.server_id.
sql/log.cc:
unneeded: the Intvar_log_event constructor calls the Log_event constructor
which does e.server_id=thd.server_id.
This makes it possible to check origin of binary from the output of 'show variables'
include/mysql_version.h.in:

The right way to fix this is to change the Field::store(longlong) method to be
Field::store(longlong, bool unsigned_flag), but this is better to do in 4.1 than in 4.0
