as a post-merge fix (the new handler tests are not passing
otherwise).
- in hash.c, don't call calc_hash if ! my_hash_inited().

WL#4144 - Lock MERGE engine children.
Committing a version of the patch merged with WL#3726
on behalf of Ingo.
Step #1: Move locking from parent to children.
MERGE children are now left in the query list of tables
after inserted there in open_tables(). So they are locked
by lock_tables() as all other tables are.
The MERGE parent does not store locks any more. It appears
in a MYSQL_LOCK with zero lock data. This is kind of a "dummy"
lock.
All other lock handling is also done directly on the children.
To protect against parent or child modifications during LOCK
TABLES, the children are detached after every statement and
attached before every statement, even under LOCK TABLES.
The children table list is removed from the query list of tables
on every detach and on close of the parent.
Step #2: Move MERGE specific functionality from SQL layer
into table handler.
Functionality moved from SQL layer (mainly sql_base.cc)
to the table handler (ha_myisammrg.cc).
Unnecessary code is removed from the SQL layer.
Step #3: Moved all MERGE specific members from TABLE
to ha_myisammrg.
Moved members from TABLE to ha_myisammrg.
Renamed some mebers.
Fixed comments.
Step #4: Valgrind and coverage testing
Valgrind did not uncover new problems.
Added purecov comments.
Added a new test for DATA/INDEX DIRECTORY options.
Changed handling of ::reset() for non-attached children.
Fixed the merge-big test.
Step #5: Fixed crashes detected during review
Changed detection when to attach/detach.
Added new tests.
Backport also the fix for Bug#44040 "MySQL allows creating a
MERGE table upon VIEWs but crashes when using it"

WL#3726 "DDL locking for all metadata objects".
After review fixes in progress.
------------------------------------------------------------
This is the first patch in series. It transforms the metadata
locking subsystem to use a dedicated module (mdl.h,cc). No
significant changes in the locking protocol.
The import passes the test suite with the exception of
deprecated/removed 6.0 features, and MERGE tables. The latter
are subject to a fix by WL#4144.
Unfortunately, the original changeset comments got lost in a merge,
thus this import has its own (largely insufficient) comments.
This patch fixes Bug#25144 "replication / binlog with view breaks".
Warning: this patch introduces an incompatible change:
Under LOCK TABLES, it's no longer possible to FLUSH a table that
was not locked for WRITE.
Under LOCK TABLES, it's no longer possible to DROP a table or
VIEW that was not locked for WRITE.

message:
WL#3726 "DDL locking for all metadata objects".
Fix for assert failures in kill.test which occured when one
tried to kill ALTER TABLE statement on merge table while it
was waiting in wait_while_table_is_used() for other connections
to close this table.
These assert failures stemmed from the fact that cleanup code
in this case assumed that temporary table representing new
version of table was open with adding to THD::temporary_tables
list while code which were opening this temporary table wasn't
always fulfilling this.
This patch changes code that opens new version of table to
always do this linking in. It also streamlines cleanup process
for cases when error occurs while we have new version of table
open.

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/5.1: Fix autoinc failing test results.
(this should be skipped when merging 5.1 into zip)
- disabled main.innodb_bug47777.test with InnoDB plugin
until fix for plugin is applied.
- disabled main.innodb-autoinc.test (failing)
- re-enabled main.innodb_bug39438.test
- added error message suppression to innodb_bug39438, as
requested by InnoDB/Oracle
- reverted change to main.innodb_bug34300 as plugin specific.
Invalid (old?) table or database name in logs
Problem was still not completely fixed, due to
qouting.
This is the server side only fix (in explain_filename),
the change from filename_to_tablename to use explain_filename
in the InnoDB code must be done before the bug is
fixed.
Had attempted to disable this test on Windows only, but the nature of this bug
does not allow for this. The master.opt file is processed before anything in
in the actual test. As a result, we must use disabled.def files to ensure
these tests are skipped on the problematic platforms.
Removed Windows-only code and updated the proper disabled.def files accordingly.
It turns out that this test case no longer fails with the discrepancy
in numbers that was the original cause for disabling this test (and showed
potential genuine issues with the query cache). Therefore
this test is being enabled after some minor adjustment of error codes and
messages.
Disabling these two tests as they are affected by this bug / causing PB2 failures
on Windows platforms. Can always disable via include/not_windows.inc if
the bug fix looks like it will take some time.
The problem is that select queries executed concurrently with
a concurrent insert on a MyISAM table could be cached if the
select started after the query cache invalidation but before
the unlock of tables performed by the concurrent insert. This
race could happen because the concurrent insert was failing
to prevent cache of select queries happening at the same time.
The solution is to add a 'uncacheable' status flag to signal
that a concurrent insert is being performed on the table and
that queries executing at the same time shouldn't cache the
results.
