Started fix in 5.0 as the same issue is here.
Revising queries used given what appears to be the scope of this test to only select the manipulated variables.
Added tests for values that are / are not multiples of 1024 to test rounding / constraints.
This behavior is not currently documented (docs bug has been opened)
Revised the test to include a test of completion_type = 1 as well as making the test more readable / worthwhile
Removed the master.opt file as it was redundant / unnecessary.
There was a problem when a DELIMITER COMMAND is not the first
command on the line. I this case an extra line feed was added
to the glob buffer and this was causing subsequent attempts
to enter this delimiter to fail.
Fixed by not adding a new line to the glob buffer if the
command being added is a DELIMITER

Bug#41112: crash in mysql_ha_close_table/get_lock_data with alter table
The problem is that the server wasn't handling robustly failures
to re-open a table during a HANDLER .. READ statement. If the
table needed to be re-opened due to it's storage engine being
altered to one that doesn't support HANDLER, a reference (dangling
pointer) to a closed table could be left in place and accessed in
later attempts to fetch from the table using the handler. Also,
if the server failed to set a error message if the re-open
failed. These problems could lead to server crashes or hangs.
The solution is to remove any references to a closed table and
to set a error if reopening a table during a HANDLER .. READ
statement fails.
- Add support for setting it as a server commandline argument
- Add support for those switches:
= no_index_merge
= no_index_merge_union
= no_index_merge_sort_union
= no_index_merge_intersection
Both of our own implementations of rint(3) were inconsistent with the
most common behavior of rint() on those platforms that have it: round
to nearest, break ties by rounding to nearest even.
Fixed by leaving just one implementation of rint() in our source tree,
and changing its behavior to match the most common native
implementations on other platforms.
slave.
In mixed mode, if we create a temporary table and do some update which switch to ROW format,
the format will keep in ROW format until the session ends or the table is dropped explicitly.
When the session ends, the temp table is dropped automaticly at cleanup time.
but it checks only current binlog format and so skip insertion of DROP TABLE instructions into binlog.
So the temp table can't be dropped correctly at slave.
Our solution is that when closing temp tables at cleanup time we check both binlog format and binlog mode,
and we could write DROP TABLE instructions into binlog if current binlog format is ROW but in MIX mode.
If secure-file-priv was set on slave, it became unable to execute
LOAD DATA INFILE statements sent from master using mixed or
statement-based replication.
This patch fixes the issue by ignoring this security restriction
and checking if the files are created and read by the slave in the
--slave-load-tmpdir while executing the SQL Thread.
Signed integer format specifier forced to print the binlog header with server_id
negative if the unsigned value sets the sign-bit ON.
Fixed with correcting the specifier to correspond to typeof(server_id) == ulong.
