Bug#42524: Function pthread_setschedprio() is defined but seems broken on i5/OS PASE
The problem is that MySQL use of pthread_setschedprio is not
supported i5/OS and the default system behavior for unsupported
calls is to emit a SIGILL signal which causes the server to
abort.
The solution is to treat the pthread_setschedprio as inexistent
when compiling binaries to i5/OS. This also does not invalidate
the fix for bug 38477 as the only supported dispatch class is
SCHED_OTHER (which is passed to pthread_setschedparam).

Fix for bug#42014: Crash, name_const with collate
Problem: some queries using NAME_CONST(.. COLLATE ...)
lead to server crash due to failed type cast.
Fix: return the underlying item's type in case of
NAME_CONST(.. COLLATE ...) to avoid wrong casting.

Bug#42495 updatexml: Assertion failed: xpath->context,
file .\item_xmlfunc.cc, line 2507
Problem:
RelativeLocationPath can appear only after a node-set expression
in the third and the fourth branches of this rule:
PathExpr :: = LocationPath
| FilterExpr
| FilterExpr '/' RelativeLocationPath
| FilterExpr '//' RelativeLocationPath
XPatch code didn't check the type of FilterExpr and crashed.
Fix:
If FilterExpr is a scalar expression
(variable reference, literal, number, scalar function call)
return error.

Bug#42188: crash and/or memory corruption with user variables
in trigger
Interchangeable calls to the mysql_change_user client function
and invocations of a trigger changing some user variable caused
a memory corruption and a crash.
The mysql_change_user API call forces TDH::cleanup() on a server
that frees user variable entries.
However it didn't reset Item_func_set_user_var::entry to NULL
because Item_func_set_user_var::cleanup() was not overloaded.
So, Item_func_set_user_var::entry held a pointer to freed memory,
that caused a crash.
The Item_func_set_user_var::cleanup method has been overloaded
to cleanup the Item_func_set_user_var::entry field.

Bug #42366: server-cert.pem expired: "Not After : Jan 27 08:54:13 2009 GMT"
Re-generated the PKI files needed.
Removed the ones that are not needed.
Updated the tests to reference the correct SSL subject.
bug#33094: Error in upgrading from 5.0 to 5.1 when table contains
triggers
and
#41385: Crash when attempting to repair a #mysql50# upgraded table
with triggers.
Problem:
1. trigger code didn't assume a table name may have
a "#mysql50#" prefix, that may lead to a failing ASSERT().
2. "ALTER DATABASE ... UPGRADE DATA DIRECTORY NAME" failed
for databases with "#mysql50#" prefix if any trigger.
3. mysqlcheck --fix-table-name didn't use UTF8 as a default
character set that resulted in (parsing) errors for tables with
non-latin symbols in their names and definitions of triggers.
Fix:
1. properly handle table/database names with "#mysql50#" prefix.
2. handle --default-character-set mysqlcheck option;
if mysqlcheck is launched with --fix-table-name or --fix-db-name
set default character set to UTF8 if no --default-character-set
option given.
Note: if given --fix-table-name or --fix-db-name option,
without --default-character-set mysqlcheck option
default character set is UTF8.
The next number (AUTO_INCREMENT) field of the table for write
rows events are not initialized, and cause some engines (innodb)
not correctly update the tables's auto_increment value.
This patch fixed this problem by honor next number fields if present.
+ add workaround for bug 38124
+ messages into the protocol when sessions are switched
+ replace error numbers by error names
+ reset of system variables to initial values per subtest
+ remove a file created by this test
+ minor improvements in structure and formatting
Added cleanup of status variables to the end of binlog_database.
Re-recorded .result file to account for cleanup statement.
NOTE: binlog.binlog_innodb also has had an FLUSH STATUS; statement added to it as well, but
adding this cleanup as a preventative measure.
Bug#36428: MY_MUTEX_INIT_FAST is used before initialization
On some thread implementations, we need a fake mutex attri-
bute as a placeholder, which we define as a global variable,
"my_fast_mutexattr". Well. that must be initialized before
used in any mutexes, and the ordering of initializations in
the API function my_init() was wrong.
Now, put my_thread_global_init(), which initializes the attri-
butes that mutexes require.
Bounds-checks and blocksize corrections were applied to user-input,
but constants in the server were trusted implicitly. If these values
did not actually meet the requirements, the user could not set change
a variable, then set it back to the (wonky) factory default or maximum
by explicitly specifying it (SET <var>=<value> vs SET <var>=DEFAULT).
Now checks also apply to the server's presets. Wonky values and maxima
get corrected at startup. Consequently all non-offsetted values the user
sees are valid, and users can set the variable to that exact value if
they so desire.
2. Avoid bad effects of bug 41925 Warning 1366 Incorrect string value:
... for column processlist.info
3. Add poll routines which ensure that subtests meet stable scenarios.
This does not change the sense of the subtests.
When substituting system constant functions with a constant result
the server was not expecting that the function may return NULL.
Fixed by checking for NULL and returning Item_null (in the relevant
collation) if the result of the system constant function was NULL.
