Following merge from 5.6.36, this merge also rejects changes that
collided with the rejection of 6ca4f693c1ce472e2b1bf7392607c2d1124b4293.
We initially rejected 6ca4f693c1ce472e2b1bf7392607c2d1124b4293 because
it was introducing a new storage engine API method.
Issue:
------
Running MTR with the --no-reorder option by specifying test cases on the
command line, without prefixing the suite name results in an error saying the
test case was not found in the main suite. This is because MTR looks for the
test case only in the main suite, and no other suites.
Fix:
----
The fix involves searching for the test in every suite if only the test name
is specified. This back-ports two bug fixes: Bug#24967869 and Bug#24365783

Problem was that dict_sys->size tries to maintain used memory
occupied by the data dictionary table and index objects.
However at least on table objects table->heap size can increase
between when table object is inserted to dict_sys and when
it is removed from dict_sys causing inconsistency on amount
of memory added to and removed from dict_sys->size variable.
Removed unnecessary dict_sys:size variable as it is really
used only for status output.
Introduced dict_sys_get_size function to calculate memory
occupied by the data dictionary table and index objects
that is then used on show engine innodb output.
dict_table_add_to_cache(),
dict_table_rename_in_cache(),
dict_table_remove_from_cache_low(),
dict_index_remove_from_cache_low(),
Remove size calculation.
srv_printf_innodb_monitor(): Use dict_sys_get_size function to
get dictionary memory allocated.
xtradb_internal_hash_tables_fill_table(): Use dict_sys_get_size
function to get dictionary memory allocated.
Backport of 7e29f2d64f from 10.1.
Create_field does not set BINARY_FLAG, so the check didn't work at all.
Also, character sets were already compared, so this check would've been
redundant (if it would've worked).
1. use Regexp_processor_pcre::set_recursion_limit() to set the
recursion limit depending on the current available stack size
2. make pcre stack frame to be estimated no less than 500 bytes.
sometimes pcre estimates it too low, even though the manual
says 500+16 bytes (it was estimated only 188 for me, actual
frame size was 512).
3. do it for embedded too
Change the semantics of thd_get_error_context_description().
It no longer expects the caller to lock LOCK_thread_count
(no caller ever did that anyway), but takes care of it internally.
Problem
rpl.rpl_mdev-11092 fails in buildbot because after starting slave in
wait_for_slave_sql_error_and_skip.inc slave is started but there may be
chances that we have not skipped the last error and Last_SQL_Errno is
still not zero untill the end of rpl_end.inc , which will compare
Last_SQL_Errno to 0. So in this this case rpl_mdev-11092 fails.
Solution
After starting slave in wait_for_slave_sql_error_and_skip.inc we will wait for
Last_SQL_Errno to become 0.
end_io_call uses uninitialized values from the new_data_cache
As such we the buffer 0 and check this before calling end_io_cache on it.
Thanks Sergey Vojtovich for the review and for this solution.
Found by Coverity (ref 972481).
A few tests assumes that the CYCLE timer is always available,
which is not true on some platforms (e.g. ARM).
Fixing the tests not to reply on the CYCLE availability.
Coverity report this as:
CID 971840 (#1 of 1): Operands don't affect result (CONSTANT_EXPRESSION_RESULT)
result_independent_of_operands: 4 | (flags & 1) is always true regardless of the values of its operands. This occurs as the logical first operand of "?:".
The C order of precidence has | of higher precidence than ?:. The
intenting implies an | of the 3 terms.
Adjust to intented meaning.
