The SE API requires mysql to notify the storage engine that
it's going to read certain tables at the beginning of the
statement (by calling start_stmt(), store_lock() or
external_lock()).
These are typically called by the lock_tables().
However SHOW CREATE TABLE is not pre-locking the tables
because it's not expected to access the data at all.
But for some view definitions (that include comparing a
date/datetime/timestamp column to a string returning
scalar subquery) the JOIN::prepare may still access data
when materializing the scalar non-correlated subquery
in Arg_comparator::can_compare_as_dates().
Fixed by not materializing the subquery when the function
is called in a SHOW/EXPLAIN/CREATE VIEW
If --log-bin is set to a directory name with the trailing 'FN_LIBCHAR',
which will be '/' on Unix like systems, and '\\' on Windows like systems.
the basename of the binlog is empty so that the created files named
'.000001' and '.index'. It is not expected.
The same thing happened to --log-bin-index, --relay-log and
--relay-log-index options.
To resolve the problem, in these cases the program should report an error
and abort.
BUG#47983: rpl_extraColmaster_myisam failed in PB2 with "Found
warnings!!"
BUG 45214 fixed the case when get_master_version_and_clock
function, used by the slave, would not report errors. The slave
now detects them and if related to transient network failures, it
prints some warnings and retries to connect. On the other hand,
if not network related, it just gives up and fails.
As such, sometimes, in PB2, the slave comes across some transient
communication issues between master and slave, while calling
get_master_version_and_clock, causing warnings print outs to the
error log. Nevertheless, in such cases slave retries to connect,
in which it succeeds, and the test case continues as it normally
would. But then, at the end of a successful test run, MTR checks
the error log, finds the unexpected warnings and considers them
harmful. This causes MTR to report error and, consequently, PB2
to report a failing test.
We fix this by adding to the global warnings suppress list the
warnings related to transient network failures only, which are
reported while in function get_master_version_and_clock.

This script failed when the user tried passwords with multiple spaces, \, # or
' characters. Now proper escaping and quoting is used in all contexts.
This problem occurs in the Perl version of this script, too, so fix it in both
places.
Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.
Bug#41756 "Strange error messages about locks from InnoDB".
In JT_EQ_REF (join_read_key()) access method,
don't try to unlock rows in the handler, unless certain that
a) they were locked
b) they are not used.
Unlocking of rows is done by the logic of the nested join loop,
and is unaware of the possible caching that the access method may
have. This could lead to double unlocking, when a row
was unlocked first after reading into the cache, and then
when taken from cache, as well as to unlocking of rows which
were actually used (but taken from cache).
Delegate part of the unlocking logic to the access method,
and in JT_EQ_REF count how many times a record was actually
used in the join. Unlock it only if it's usage count is 0.
Implemented review comments.

WHERE clauses with "outer_value_list NOT IN subselect" were
handled incorrectly if the outer value list contained multiple
items where at least one of these could be NULL. The first
outer record with NULL value was handled correctly, but if a
second record with NULL value existed, the optimizer would
choose to reuse the result it got on the last execution of the
subselect. This is incorrect if the outer value list has
multiple items.
The fix is to make Item_in_optimizer::val_int (in
item_cmpfunc.cc) reuse the result of the latest execution
for NULL values only if all values in the outer_value_list
are NULL.

branches/zip: This test has been problematic for sometime now. The underlying
bug is that the data dictionaries get out of sync. In the AUTOINC code we
try and apply salve to the symptoms. In the past MySQL made some unrelated
change and the dictionaries stopped getting out of sync and this test started
to fail. Now, it seems they have reverted that changed and the test is
passing again. I suspect this is not he last time that this test will change.

branches/zip: Fix corruption of buf_pool->LRU_old and improve debug assertions.
This was reported as Issue #381.
buf_page_set_old(): Assert that blocks may only be set old if
buf_pool->LRU_old is initialized and buf_pool->LRU_old_len is nonzero.
Assert that buf_pool->LRU_old points to the block at the old/new boundary.
buf_LRU_old_adjust_len(): Invoke buf_page_set_old() after adjusting
buf_pool->LRU_old and buf_pool->LRU_old_len, in order not to violate
the added assertions.
buf_LRU_old_init(): Replace buf_page_set_old() with a direct
assignment to bpage->old, because these loops that initialize all the
blocks would temporarily violate the assertions about
buf_pool->LRU_old.
buf_LRU_remove_block(): When setting buf_pool->LRU_old = NULL, also
clear all bpage->old flags and set buf_pool->LRU_old_len = 0.
buf_LRU_add_block_to_end_low(), buf_LRU_add_block_low(): Move the
buf_page_set_old() call later in order not to violate the debug
assertions. If buf_pool->LRU_old is NULL, set old=FALSE.
buf_LRU_free_block(): Replace the UNIV_LRU_DEBUG assertion with a
dummy buf_page_set_old() call that performs more thorough checks.
buf_LRU_validate(): Do not tolerate garbage in buf_pool->LRU_old_len
even if buf_pool->LRU_old is NULL. Check that bpage->old is monotonic.
buf_relocate(): Make the UNIV_LRU_DEBUG checks stricter.

buf_pool_t::LRU_old_len.
