"BIT_AND() result in GROUP BY different when SQL_BIG_RESULT used"
return value of BIT_AND changed to BIGINT SIGNED
Also the patch fixes another bug: when temporary table is in use and one of
values in group is NULL, BIT_AND always returns zero.
Fixed it to always skip null values.
"CHANGE MASTER makes SQL thread restart from coordinates of I/O thread".
So, in CHANGE MASTER:
when it seems reasonable that the user did not want to discontinue
its replication (i.e. when he is not specifying host or port or master_log_file
or master_log_pos; this will be documented), set the coordinates of the
I/O thread to those of the SQL thread. This way, the SQL thread will see
no discontinuity in the relay log (i.e. will skip no events), because
the I/O thread will fill the brand new relay log with the events which
are just after the position where the SQL thread had stopped
(before CHANGE MASTER was issued).
And a new test for this bug.
rli->save_temporary_tables and slave_open_temp_tables
(in old 4.0 you could make "SHOW STATUS LIKE 'slave_open_temp_tables'" grow
indefinitely by doing RESET SLAVE and replicating always the same CREATE
TEMPORARY TABLE).
It's critical to reset save_temporary_tables to 0 (otherwise you may later
read memory which has been freed) so this changeset should go into 4.1.
"If 2 master threads with same-name temp table, slave makes bad binlog"
and (two birds with one stone) for
BUG#1240 "slave of slave breaks when STOP SLAVE was issud on parent slave
and temp tables".
Here is the design change:
in a slave running with --log-slave-updates, events are now logged with the
thread id they had on the master. So no more id conflicts between master threads,
but introduces id conflicts between one master thread and one normal
client thread connected to the slave. This is solved by storing the server id
in the temp table's name.
New test which requires mysql-test-run to be run with --manager,
otherwise it will be skipped.
Undoing a Monty's change (hum, a chill runs down my spine ;) which was
"Cleanup temporary tables when slave ends" in ChangeSet 1.1572.1.1.
query_alloc_block_size, query_prealloc_size, range_alloc_block_size,transaction_alloc_block_size and transaction_prealloc_size
Add more checks for "out of memory" detection in range optimization
Rotate_log_event::exec_event() believed that the relay log was corrupted. Fixed it
by moving the test for corruption to Start_log_event::exec_event().
Changed Rotate_log_event::exec_event() to not increment positions when the
event is seen in the middle of a transaction.
I did a separate commit in 4.1 (so this should not be merged to 4.0) because
code is a bit different in 4.1.
A test to see if the slave detects when the master died while writing a
transaction to the binlog (uses a forged truncated binlog I made).
Add quoting for use `database` for mysqlbinlog
Removed test ins0000001
Add support for --replace for exec in mysqltest
Don't refer to install dir in mysqlbinlog.result
