mysql_server_init() now returns error code if something went wrong (Bug #2062)
Don't use my_fopen() when reading symlink information as this may cause problems when a lot of files are opened.
Free thread keys with pthread_key_delete() instead of relying on automatic free. (Bug #2062)
Fixed bug in UNION statement with alias '*'. (Bug #1249)
Fixed a bug in DELETE ... ORDER BY ... LIMIT where the rows where not deleted in the proper order. (Bug #1024).
FOUND_ROWS() could return incorrect number of rows after a query with an impossible WHERE condition.
HOW DATABASES doesn't anymore show .sym files (on windows) that doesn't point to a valid directory. (Bug #1385)
SQL_BIG_RESULT used": now BIT_AND() always returns 18446744073709551615
if no rows were found.
This patch also fixes bug #1972: "BIT_AND() and BIT_OR() still return
a *signed* 64bit value"
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>).
