Repairing MyISAM table with fulltext indexes and low
myisam_sort_buffer_size may crash the server.
Estimation of number of index entries was done incorrectly,
causing further assertion failure or server crash.
Docs note: min value for myisam_sort_buffer_size has been
changed from 4 to 4096.
being logged to slow query log
The problem is that the execution time for a multi-statement
stored procedure as a whole may not be accurate, and thus not
be entered into the slow query log even if the total time
exceeds long_query_time. The reason for this is that
THD::utime_after_lock used for time calculation may be reset
at the start of each new statement, possibly leaving the total
SP execution equal to the time spent executing the last
statement in the SP.
This patch stores the utime on start of SP execution, and
restores it on exit of SP execution. A test is added.
assertion .\filesort.cc, line 797
A query with the "ORDER BY @@some_system_variable" clause,
where @@some_system_variable is NULL, causes assertion
failure in the filesort procedures.
The reason of the failure is in the value of
Item_func_get_system_var::maybe_null: it was unconditionally
set to false even if the value of a variable was NULL.
The problem is that creating a event could fail if the value of
the variable server_id didn't fit in the originator column of
the event system table. The cause is two-fold: it was possible
to set server_id to a value outside the documented range (from
0 to 2^32-1) and the originator column of the event table didn't
have enough room for values in this range.
The log tables (general_log and slow_log) also don't have a proper
column type to store the server_id and having a large server_id
value could prevent queries from being logged.
The solution is to ensure that all system tables that store the
server_id value have a proper column type (int unsigned) and that
the variable can't be set to a value that is not within the range.
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.

The minimum value differs depending on the OS and mysqld build, so that the test fail spradically.
The check of this value has been changed from check of concrete values to the check of a range that is near by the expected value.
which were determined by the server depending on the os. The solution is to disable warnings in general.
The check of the values only have been done for Linux and Windows. Now, the check has been changed to the check of
ranges (not more concrete values) being near by the expected (set) values.
