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>).
- postinstall of the Mac OS X PKG failed as a parameter for
mysql_install_db was changed for MySQL 4.1
- postinstall of the Server RPM failed as mysql_create_system_tables was
missing from the file list
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.
This bug happens under Windows & Embedded server
Reason is that pthread_self() always returns NULL in this case.
This confuses thr_lock function and it doesn't stop
thread inserting in the write-locked table.
Global problem is that there's no way under Windows to get
unique thread handle for working thread.
Monty made a workaround for server - we store the thread's handle
we get when we create thread in the thread-specific variable.
This doesn't work with the embedded library for we don't control
thread creation there.
I added code that sets CurrentThreadId as the pthread_self
for the embedded library.
It seems to solve problem because it's unique and we don't use
pthread_self as a parameter for thread functions in embedded library.
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.
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).
