This patch:

- Moves all definitions from the mysql_priv.h file into
  header files for the component where the variable is
  defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

This patch prevents system threads and system table accesses from
using user-specified values for "lock_wait_timeout". Instead all
such accesses are done using the default value (1 year).

This prevents background tasks (such as replication, events, 
accessing stored function definitions, logging, reading time-zone
information, etc.) from failing in cases where the global value
of "lock_wait_timeout" is set very low.

The patch also simplifies the open tables API. Rather than adding
another convenience function for opening and locking system tables,
this patch removes most of the existing convenience functions for
open_and_lock_tables_derived(). Before, open_and_lock_tables() was
a convenience function that enforced derived tables handling, while
open_and_lock_tables_derived() was the main function where derived
tables handling was optional. Now, this convencience function is
gone and the main function is renamed to open_and_lock_tables(). 

No test case added as it would have required the use of --sleep to
check that system threads and system tables have a different timeout
value from the user-specified "lock_wait_timeout" system variable.

Deployed DBUG_ASSERT before the conditional binlog format
restore.

As part of BUG@39934 fix, the public:
 - THD::current_stmt_binlog_row_based 
variable had been removed and replaced by a private variable:
 - THD::current_stmt_binlog_format. 

THD was refactored and some modifiers and accessors were
implemented for the new variable.

However, due to a bad merge, the
THD::current_stmt_binlog_row_based variable is back as a public
member of THD. This in itself is already potentially
harmful. What's even worse is that while merging some more
patches and resolving conflicts, the variable started being used
again, which is obviously wrong.

To fix this we:
  1. remove the extraneous variable from sql_class.h
  2. revert a bad merge for BUG#49132
  3. merge BUG#49132 properly again (actually, making use of the
     cset used to merge the original patch to mysql-pe).

In RBR, DDL statement will change binlog format to non row-based
format before it is binlogged, but the binlog format was not be
restored, and then manipulating a temporary table can not reset binlog
format to row-based format rightly. So that the manipulated statement
is binlogged with statement-based format.

To fix the problem, restore the state of binlog format after the DDL
statement is binlogged.

mysql-test/extra/rpl_tests/rpl_tmp_table_and_DDL.test:
  Added the test file to verify if executing DDL statement before
  trying to manipulate a temporary table causes row-based replication
  to break with error 'table does not exist'.

  should be row-based after the bug49132 is fixed IN RBR.

  WL#4284 "Transactional DDL locking"
  A review fix.
  Since WL#4284 implementation separated MDL_request and MDL_ticket,
  MDL_request becamse a utility object necessary only to get a ticket.
  Store it by-value in TABLE_LIST with the intent to merge
  MDL_request::key with table_list->table_name and table_list->db
  in future.
  Change the MDL subsystem to not require MDL_requests to
  stay around till close_thread_tables().
  Remove the list of requests from the MDL context.
  Requests for shared metadata locks acquired in open_tables()
  are only used as a list in recover_from_failed_open_table_attempt(),
  which calls mdl_context.wait_for_locks() for this list.
  To keep such list for recover_from_failed_open_table_attempt(),
  introduce a context class (Open_table_context), that collects
  all requests.
  A lot of minor cleanups and simplications that became possible
  with this change.


sql/event_db_repository.cc:
  Remove alloc_mdl_requests(). Now MDL_request instance is a member
  of TABLE_LIST, and init_one_table() initializes it.
sql/ha_ndbcluster_binlog.cc:
  Remove now unnecessary declaration and initialization
  of binlog_mdl_request.
sql/lock.cc:
  No need to allocate MDL requests in lock_table_names() now.
sql/log.cc:
  Use init_one_table() method, remove alloc_mdl_requests(),
  which is now unnecessary.
sql/log_event.cc:
  No need to allocate mdl_request separately now.
  Use init_one_table() method.
sql/log_event_old.cc:
  Update to the new signature of close_tables_for_reopen().
sql/mdl.cc:
  Update try_acquire_exclusive_lock() to be more easy to use.
  Function lock_table_name_if_not_cached() has been removed.
  Make acquire_shared_lock() signature consistent with
  try_acquire_exclusive_lock() signature.
  Remove methods that are no longer used.
  Update comments.
sql/mdl.h:
  Implement an assignment operator that doesn't
  copy MDL_key (MDL_key::operator= is private and
  should remain private).
  This is a hack to work-around assignment of TABLE_LIST
  by value in several places. Such assignments violate
  encapsulation, since only perform a shallow copy.
  In most cases these assignments are a hack on their own.
sql/mysql_priv.h:
  Update signatures of close_thread_tables() and close_tables_for_reopen().
sql/sp.cc:
  Allocate TABLE_LIST in thd->mem_root.
  Use init_one_table().
sql/sp_head.cc:
  Use init_one_table().
  Remove thd->locked_tables_root, it's no longer needed.
sql/sql_acl.cc:
  Use init_mdl_requests() and init_one_table().
sql/sql_base.cc:
  Update to new signatures of try_acquire_shared_lock() and
  try_acquire_exclusive_lock().
  Remove lock_table_name_if_not_cached().
  Fix a bug in open_ltable() that would not return ER_LOCK_DEADLOCK
  in case of a failed lock_tables() and a multi-statement
  transaction.
  Fix a bug in open_and_lock_tables_derived() that would
  not return ER_LOCK_DEADLOCK in case of a multi-statement
  transaction and a failure of lock_tables().
  Move assignment of enum_open_table_action to a method of Open_table_context, a new class that maintains information
  for backoff actions.
  Minor rearrangements of the code.
  Remove alloc_mdl_requests() in functions that work with system
  tables: instead the patch ensures that callers always initialize
  TABLE_LIST argument.
sql/sql_class.cc:
  THD::locked_tables_root is no more.
sql/sql_class.h:
  THD::locked_tables_root is no more.
  Add a declaration for Open_table_context class.
sql/sql_delete.cc:
  Update to use the simplified MDL API.
sql/sql_handler.cc:
  TABLE_LIST::mdl_request is stored by-value now.
  Ensure that mdl_request.ticket is NULL for every request
  that is passed into MDL, to satisfy MDL asserts.
  @ sql/sql_help.cc
  Function open_system_tables_for_read() no longer initializes
  mdl_requests.
  Move TABLE_LIST::mdl_request initialization closer to
  TABLE_LIST initialization.
sql/sql_help.cc:
  Function open_system_tables_for_read() no longer initializes
  mdl_requests.
  Move TABLE_LIST::mdl_request initialization closer to
  TABLE_LIST initialization.
sql/sql_insert.cc:
  Remove assignment by-value of TABLE_LIST in
  TABLEOP_HOOKS. We can't carry over a granted
  MDL ticket from one table list to another.
sql/sql_parse.cc:
  Change alloc_mdl_requests() -> init_mdl_requests().
  @todo We can remove init_mdl_requests() altogether
  in some places: all places that call add_table_to_list()
  already have mdl requests initialized.
sql/sql_plugin.cc:
  Use init_one_table().
  THD::locked_tables_root is no more.
sql/sql_servers.cc:
  Use init_one_table().
sql/sql_show.cc:
  Update acquire_high_priority_shared_lock() to use
  TABLE_LIST::mdl_request rather than allocate an own.
  Fix get_trigger_table_impl() to use init_one_table(),
  check for out of memory, follow the coding style.
sql/sql_table.cc:
  Update to work with TABLE_LIST::mdl_request by-value.
  Remove lock_table_name_if_not_cached().
  The code that used to delegate to it is quite simple and
  concise without it now.
sql/sql_udf.cc:
  Use init_one_table().
sql/sql_update.cc:
  Update to use the new signature of close_tables_for_reopen().
sql/table.cc:
  Move re-setting of mdl_requests for prepared statements
  and stored procedures from close_thread_tables() to
  reinit_stmt_before_use().
  Change alloc_mdl_requests() to init_mdl_requests().
  init_mdl_requests() is a hack that can't be deleted
  until we don't have a list-aware TABLE_LIST constructor.
  Hopefully its use will be minimal
sql/table.h:
  Change alloc_mdl_requests() to init_mdl_requests()
  TABLE_LIST::mdl_request is stored by value.
sql/tztime.cc:
  We no longer initialize mdl requests in open_system_tables_for*()
  functions. Move this initialization closer to initialization
  of the rest of TABLE_LIST members.
storage/myisammrg/ha_myisammrg.cc:
  Simplify mdl_request initialization.

Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order
WL#4284: Transactional DDL locking

This is a prerequisite patch:

These changes are intended to split lock requests from granted
locks and to allow the memory and lifetime of granted locks to
be managed within the MDL subsystem. Furthermore, tickets can
now be shared and therefore are used to satisfy multiple lock
requests, but only shared locks can be recursive.

The problem is that the MDL subsystem morphs lock requests into
granted locks locks but does not manage the memory and lifetime
of lock requests, and hence, does not manage the memory of
granted locks either. This can be problematic because it puts the
burden of tracking references on the users of the subsystem and
it can't be easily done in transactional contexts where the locks
have to be kept around for the duration of a transaction.

Another issue is that recursive locks (when the context trying to
acquire a lock already holds a lock on the same object) requires
that each time the lock is granted, a unique lock request/granted
lock structure structure must be kept around until the lock is
released. This can lead to memory leaks in transactional contexts
as locks taken during the transaction should only be released at
the end of the transaction. This also leads to unnecessary wake
ups (broadcasts) in the MDL subsystem if the context still holds
a equivalent of the lock being released.

These issues are exacerbated due to the fact that WL#4284 low-level
design says that the implementation should "2) Store metadata locks
in transaction memory root, rather than statement memory root" but
this is not possible because a memory root, as implemented in mysys,
requires all objects allocated from it to be freed all at once.

This patch combines review input and significant code contributions
from Konstantin Osipov (kostja) and Dmitri Lenev (dlenev).


mysql-test/r/mdl_sync.result:
  Add test case result.
mysql-test/t/mdl_sync.test:
  Add test case for shared lock upgrade case.

sql/ha_ndbcluster_binlog.cc:
  Use new function names to initialize MDL lock requests.
sql/lock.cc:
  Rename MDL functions.
sql/log_event.cc:
  The MDL request now holds the table and database name data (MDL_KEY).
sql/mdl.cc:
  Move the MDL key to the MDL_LOCK structure in order to make the
  object suitable for allocation from a fixed-size allocator. This
  allows the simplification of the lists in the MDL_LOCK object,
  which now are just two, one for granted tickets and other for
  waiting (upgraders) tickets.
  
  Recursive requests for a shared lock on the same object can now
  be granted using the same lock ticket. This schema is only used
  for shared locks because that the only case that matters. This
  is used to avoid waste of resources in case a context (connection)
  already holds a shared lock on a object.
sql/mdl.h:
  Introduce a metadata lock object key which is used  to uniquely
  identify lock objects.
  
  Separate the structure used to represent pending lock requests
  from the structure used to represent granted metadata locks.
  
  Rename functions used to manipulate locks requests in order to
  have a more consistent function naming schema.
sql/sp_head.cc:
  Rename mdl_alloc_lock to mdl_request_alloc.

  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.

  These assert failures stemmed from the fact that cleanup code

  Instead of relying on this parameter and related behavior FLUSH
  TABLES WITH READ LOCK now takes global shared metadata lock.
sql/handler.cc:
  update_frm_version():
    Directly update TABLE_SHARE::mysql_version member instead of
    going through all TABLE instances for this table (old code was a
    legacy from pre-table-definition-cache days).
sql/lock.cc:
  Use new metadata locking subsystem. Threw away most of functions
  related to name locking as now one is supposed to use metadata
  locking API instead.  In lock_global_read_lock() and
  unlock_global_read_lock() in order to avoid problems with global
  read lock sneaking in at the moment when we perform FLUSH TABLES
  or ALTER TABLE under LOCK TABLES and when tables being reopened
  are protected only by metadata locks we also have to take global
  shared meta data lock.
sql/log_event.cc:
  Adjusted code to work with new metadata locking subsystem.  For
  tables open by slave thread for applying RBR events allocate
  memory for lock request object in the same chunk of memory as
  TABLE_LIST objects for them. In order to ensure that we keep these
  objects around until tables are open always close tables before
  calling Relay_log_info::clear_tables_to_lock(). Use new auxiliary
  Relay_log_info::slave_close_thread_tables() method to enforce
  this.
sql/log_event_old.cc:
  Adjusted code to work with new metadata locking subsystem.  Since
  for tables open by slave thread for applying RBR events memory for
  lock request object is allocated in the same chunk of memory as
  TABLE_LIST objects for them we have to ensure that we keep these
  objects around until tables are open. To ensure this we always
  close tables before calling
  Relay_log_info::clear_tables_to_lock(). To enfore this we use
  new auxiliary Relay_log_info::slave_close_thread_tables()
  method.
sql/mdl.cc:
  Implemented new metadata locking subsystem and API described in
  WL3726 "DDL locking for all metadata objects".
sql/mdl.h:
  Implemented new metadata locking subsystem and API described in
  WL3726 "DDL locking for all metadata objects".
sql/mysql_priv.h:
  - close_thread_tables()/close_tables_for_reopen() now has one more
    argument which indicates that metadata locks should be released
    but not removed from the context in order to be used later in
    mdl_wait_for_locks() and tdc_wait_for_old_version().
  - close_cached_table() routine is no longer public.
  - Thread waiting in wait_while_table_is_used() can be now killed
    so this function returns boolean to make caller aware of such
    situation.
  - We no longer have  table cache as separate entity instead used
    and unused TABLE instances are linked to TABLE_SHARE objects in
    table definition cache.
  - Now third argument of open_table() is also used for requesting
    table repair or auto-discovery of table's new definition. So its
    type was changed from bool to enum.
  - Added tdc_open_view() function for opening view by getting its
    definition from disk (and table cache in future).
  - reopen_name_locked_table() no longer needs "link_in" argument as
    now we have exclusive metadata locks instead of dummy TABLE
    instances when this function is called.
  - find_locked_table() now takes head of list of TABLE instances
    instead of always scanning through THD::open_tables list. Also
    added find_write_locked_table() auxiliary.
  - reopen_tables(), close_cached_tables() no longer have
    mark_share_as_old and wait_for_placeholder arguments. Instead of
    relying on this parameters and related behavior FLUSH TABLES
    WITH READ LOCK now takes global shared metadata lock.
  - We no longer need drop_locked_tables() and
    abort_locked_tables().
  - mysql_ha_rm_tables() now always assume that LOCK_open is not
    acquired by caller.
  - Added notify_thread_having_shared_lock() callback invoked by
    metadata locking subsystem when acquiring an exclusive lock, for
    each thread that has a conflicting shared metadata lock.
  - Introduced expel_table_from_cache() as replacement for
    remove_table_from_cache() (the main difference is that this new
    function assumes that caller follows metadata locking protocol
    and never waits).
  - Threw away most of functions related to name locking. One should
    use new metadata locking subsystem and API instead.
sql/mysqld.cc:
  Got rid of call initializing/deinitializing table cache since now
  it is embedded into table definition cache. Added calls for
  initializing/ deinitializing metadata locking subsystem.
sql/rpl_rli.cc:
  Introduced auxiliary Relay_log_info::slave_close_thread_tables()
  method which is used for enforcing that we always close tables
  open for RBR before deallocating TABLE_LIST elements and MDL_LOCK
  objects for them.
sql/rpl_rli.h:
  Introduced auxiliary Relay_log_info::slave_close_thread_tables()
  method which is used for enforcing that we always close tables
  open for RBR before deallocating TABLE_LIST elements and MDL_LOCK
  objects for them.
sql/set_var.cc:
  close_cached_tables() no longer has wait_for_placeholder argument.
  Instead of relying on this parameter and related behavior FLUSH
  TABLES WITH READ LOCK now takes global shared metadata lock.
sql/sp_head.cc:
  For tables added to the statement's table list by prelocking
  algorithm we allocate these objects either on the same memory as
  corresponding table list elements or on THD::locked_tables_root
  (if we are building table list for LOCK TABLES).
sql/sql_acl.cc:
  Allocate metadata lock requests objects (MDL_LOCK) on execution
  memory root in cases when we use stack TABLE_LIST objects to open
  tables.  Got rid of redundant code by using unlock_locked_tables()
  function.
sql/sql_base.cc:
  Changed code to use new MDL subsystem. Got rid of separate table
  cache.  Now used and unused TABLE instances are linked to the
  TABLE_SHAREs in table definition cache.
  
  check_unused():
    Adjusted code to the fact that we no longer have separate table
    cache.  Removed dead code.
  table_def_free():
    Free TABLE instances referenced from TABLE_SHARE objects before
    destroying table definition cache.
  get_table_share():
    Added assert which ensures that noone will be able to access
    table (and its share) without acquiring some kind of metadata
    lock first.
  close_handle_and_leave_table_as_lock():
    Adjusted code to the fact that TABLE instances now are linked to
    list in TABLE_SHARE.
  list_open_tables():
    Changed this function to use table definition cache instead of
    table cache.
  free_cache_entry():
    Unlink freed TABLE elements from the list of all TABLE instances
    for the table in TABLE_SHARE.
  kill_delayed_thread_for_table():
    Added auxiliary for killing delayed insert threads for
    particular table.
  close_cached_tables():
    Got rid of wait_for_refresh argument as we now rely on global
    shared metadata lock to prevent FLUSH WITH READ LOCK sneaking in
    when we are reopening tables. Heavily reworked this function to
    use new MDL code and not to rely on separate table cache entity.
  close_open_tables():
    We no longer have separate table cache.
  close_thread_tables():
    Release metadata locks after closing all tables. Added skip_mdl
    argument which allows us not to remove metadata lock requests
    from the context in case when we are going to use this requests
    later in mdl_wait_for_locks() and tdc_wait_for_old_versions().
  close_thread_table()/close_table_for_reopen():
    Since we no longer have separate table cache and all TABLE
    instances are linked to TABLE_SHARE objects in table definition
    cache we have to link/unlink TABLE object to/from appropriate
    lists in the share.
  name_lock_locked_table():
   Moved redundant code to find_write_locked_table() function and
    adjusted code to the fact that wait_while_table_is_used() can
    now return with an error if our thread is killed.
  reopen_table_entry():
    We no longer need "link_in" argument as with MDL we no longer
    call this function with dummy TABLE object pre-allocated and
    added to the THD::open_tables. Also now we add newly-open TABLE
    instance to the list of share's used TABLE instances.
  table_cache_insert_placeholder():
    Got rid of name-locking legacy.
  lock_table_name_if_not_cached():
    Moved to sql_table.cc the only place where it is used. It was
    also reimplemented using new MDL API.
  open_table():
    - Reworked this function to use new MDL subsystem.
    - Changed code to deal with table definition cache directly
      instead of going through separate table cache.
    - Now third argument is also used for requesting table repair
      or auto-discovery of table's new definition. So its type was
      changed from bool to enum.
  find_locked_table()/find_write_locked_table():
    Accept head of list of TABLE objects as first argument and use
    this list instead of always searching in THD::open_tables list.
    Also added auxiliary for finding write-locked locked tables.
  reopen_table():
    Adjusted function to work with new MDL subsystem and to properly
    manuipulate with lists of used/unused TABLE instaces in
    TABLE_SHARE.
  reopen_tables():
    Removed mark_share_as_old parameter. Instead of relying on it
    and related behavior FLUSH TABLES WITH READ LOCK now takes
    global shared metadata lock. Changed code after removing
    separate table cache.
  drop_locked_tables()/abort_locked_tables():
    Got rid of functions which are no longer needed.
    unlock_locked_tables():
    Moved this function from sql_parse.cc and changed it to release
    memory which was used for allocating metadata lock requests for
    tables open and locked by LOCK TABLES.
  tdc_open_view():
    Intoduced function for opening a view by getting its definition
    from disk (and table cache in future).
  reopen_table_entry():
    Introduced function for opening table definitions while holding
    exclusive metatadata lock on it.
  open_unireg_entry():
   Got rid of this function. Most of its functionality is relocated
    to open_table() and open_table_fini() functions, and some of it
    to reopen_table_entry() and tdc_open_view(). Also code
    resposible for auto-repair and auto-discovery of tables was
    moved to separate function.
  open_table_entry_fini():
    Introduced function which contains common actions which finalize
    process of TABLE object creation.
  auto_repair_table():
    Moved code responsible for auto-repair of table being opened
    here.
  handle_failed_open_table_attempt()
    Moved code responsible for handling failing attempt to open
    table to one place (retry due to lock conflict/old version,
    auto-discovery and repair).
  open_tables():
    - Flush open HANDLER tables if they have old version of if there
      is conflicting metadata lock against them (before this moment
      we had this code in open_table()).
    - When we open view which should be processed via derived table
      on the second execution of prepared statement or stored
      routine we still should call open_table() for it in order to
      obtain metadata lock on it and prepare its security context.
    - In cases when we discover that some special handling of
      failure to open table is needed call
      handle_failed_open_table_attempt() which handles all such
      scenarios.
  open_ltable():
    Handling of various special scenarios of failure to open a table
    was moved to separate handle_failed_open_table_attempt()
    function.
  remove_db_from_cache():
    Removed this function as it is no longer used.
  notify_thread_having_shared_lock():
    Added callback which is invoked by MDL subsystem when acquiring
    an exclusive lock, for each thread that has a conflicting shared
    metadata lock.
  expel_table_from_cache():
    Introduced function for removing unused TABLE instances. Unlike
    remove_table_from_cache() it relies on caller following MDL
    protocol and having appropriate locks when calling it and thus
    does not do any waiting if table is still in use.
  tdc_wait_for_old_version():
    Added function which allows open_tables() to wait in cases when
    we discover that we should back-off due to presence of old
    version of table.
  abort_and_upgrade_lock():
    Use new MDL calls.
  mysql_wait_completed_table():
    Got rid of unused function.
  open_system_tables_for_read/for_update()/performance_schema_table():
    Allocate MDL_LOCK objects on execution memory root in cases when
    TABLE_LIST objects for corresponding tables is allocated on
    stack.
  close_performance_schema_table():
    Release metadata locks after closing tables.
  ******
  Use I_P_List for free/used tables list in the table share.
sql/sql_binlog.cc:
  Use Relay_log_info::slave_close_thread_tables() method to enforce
  that we always close tables open for RBR before deallocating
  TABLE_LIST elements and MDL_LOCK objects for them.
sql/sql_class.cc:
  Added meta-data locking contexts as part of Open_tables_state
  context.  Also introduced THD::locked_tables_root memory root
  which is to be used for allocating MDL_LOCK objects for tables in
  LOCK TABLES statement (end of lifetime for such objects is UNLOCK
  TABLES so we can't use statement or execution root for them).
sql/sql_class.h:
  Added meta-data locking contexts as part of Open_tables_state
  context.  Also introduced THD::locked_tables_root memory root
  which is to be used for allocating MDL_LOCK objects for tables in
  LOCK TABLES statement (end of lifetime for such objects is UNLOCK
  TABLES so we can't use statement or execution root for them).
  
  Note: handler_mdl_context and locked_tables_root and
  mdl_el_root will be removed by subsequent patches.
sql/sql_db.cc:
  mysql_rm_db() does not really need to call remove_db_from_cache()
  as it drops each table in the database using
  mysql_rm_table_part2(), which performs all necessary operations on
  table (definition) cache.
sql/sql_delete.cc:
  Use the new metadata locking API for TRUNCATE.
sql/sql_handler.cc:
  Changed HANDLER implementation to use new metadata locking
  subsystem.  Note that MDL_LOCK objects for HANDLER tables are
  allocated in the same chunk of heap memory as TABLE_LIST object
  for those tables.
sql/sql_insert.cc:
  mysql_insert():
    find_locked_table() now takes head of list of TABLE object as
    its argument instead of always scanning through THD::open_tables
    list.
  handle_delayed_insert():
    Allocate metadata lock request object for table open by delayed
    insert thread on execution memroot.  create_table_from_items():
    We no longer allocate dummy TABLE objects for tables being
    created if they don't exist. As consequence
    reopen_name_locked_table() no longer has link_in argument.
    open_table() now has one more argument which is not relevant for
    temporary tables.
sql/sql_parse.cc:
  - Moved unlock_locked_tables() routine to sql_base.cc and made
    available it in other files. Got rid of some redundant code by
    using this function.
  - Replaced boolean TABLE_LIST::create member with enum
    open_table_type member.
  - Use special memory root for allocating MDL_LOCK objects for
    tables open and locked by LOCK TABLES (these object should live
    till UNLOCK TABLES so we can't allocate them on statement nor
    execution memory root). Also properly set metadata lock
    upgradability attribure for those tables.
  - Under LOCK TABLES it is no longer allowed to flush tables which
    are not write-locked as this breaks metadata locking protocol
    and thus potentially might lead to deadlock.
  - Added auxiliary adjust_mdl_locks_upgradability() function.
sql/sql_partition.cc:
  Adjusted code to the fact that reopen_tables() no longer has
  "mark_share_as_old" argument. Got rid of comments which are no
  longer true.
sql/sql_plist.h:
  Added I_P_List template class for parametrized intrusive doubly
  linked lists and I_P_List_iterator for corresponding iterator.
  Unlike for I_List<> list elements of such list can participate in
  several lists. Unlike List<> such lists are doubly-linked and
  intrusive.
sql/sql_plugin.cc:
  Allocate metadata lock requests objects (MDL_LOCK) on execution
  memory root in cases when we use stack TABLE_LIST objects to open
  tables.
sql/sql_prepare.cc:
  Replaced boolean TABLE_LIST::create member with enum
  open_table_type member.  This allows easily handle situation in
  which instead of opening the table we want only to take exclusive
  metadata lock on it.
sql/sql_rename.cc:
  Use new metadata locking subsystem in implementation of RENAME
  TABLE.
sql/sql_servers.cc:
  Allocate metadata lock requests objects (MDL_LOCK) on execution
  memory root in cases when we use stack TABLE_LIST objects to open
  tables. Got rid of redundant code by using unlock_locked_tables()
  function.
sql/sql_show.cc:
  Acquire shared metadata lock when we are getting information for
  I_S table directly from TABLE_SHARE without doing full-blown table
  open.  We use high priority lock request in this situation in
  order to avoid deadlocks.
  Also allocate metadata lock requests objects (MDL_LOCK) on
  execution memory root in cases when TABLE_LIST objects are also
  allocated there
sql/sql_table.cc:
  mysql_rm_table():
    Removed comment which is no longer relevant.
  mysql_rm_table_part2():
    Now caller of mysql_ha_rm_tables() should not own LOCK_open.
    Adjusted code to use new metadata locking subsystem instead of
    name-locks.
  lock_table_name_if_not_cached():
    Moved this function from sql_base.cc to this file and
    reimplemented it using metadata locking API.
  mysql_create_table():
    Adjusted code to use new MDL API.
  wait_while_table_is_used():
    Changed function to use new MDL subsystem. Made thread waiting
    in it killable (this also led to introduction of return value so
    caller can distinguish successful executions from situations
    when waiting was aborted).
  close_cached_tables():
    Thread waiting in this function is killable now. As result it
    has return value for distinguishing between succes and failure.
    Got rid of redundant boradcast_refresh() call.
  prepare_for_repair():
    Use MDL subsystem instead of name-locks.
  mysql_admin_table():
    mysql_ha_rm_tables() now always assumes that caller doesn't own
    LOCK_open.
  mysql_repair_table():
    We should mark all elements of table list as requiring
    upgradable metadata locks.
  mysql_create_table_like():
    Use new MDL subsystem instead of name-locks.
  create_temporary_tables():
    We don't need to obtain metadata locks when creating temporary
    table.
  mysql_fast_or_online_alter_table():
    Thread waiting in wait_while_table_is_used() is now killable.
  mysql_alter_table():
    Adjusted code to work with new MDL subsystem and to the fact
    that threads waiting in what_while_table_is_used() and
    close_cached_table() are now killable.
sql/sql_test.cc:
  We no longer have separate table cache. TABLE instances are now
  associated with/linked to TABLE_SHARE objects in table definition
  cache.
sql/sql_trigger.cc:
  Adjusted code to work with new metadata locking subsystem.  Also
  reopen_tables() no longer has mark_share_as_old argument (Instead
  of relying on this parameter and related behavior FLUSH TABLES
  WITH READ LOCK now takes global shared metadata lock).
sql/sql_udf.cc:
  Allocate metadata lock requests objects (MDL_LOCK) on execution
  memory root in cases when we use stack TABLE_LIST objects to open
  tables.
sql/sql_update.cc:
  Adjusted code to work with new meta-data locking subsystem.
sql/sql_view.cc:
  Added proper meta-data locking to implementations of
  CREATE/ALTER/DROP VIEW statements. Now we obtain exclusive
  meta-data lock on a view before creating/ changing/dropping it.
  This ensures that all concurrent statements that use this view
  will finish before our statement will proceed and therefore we
  will get correct order of statements in the binary log.
  Also ensure that TABLE_LIST::mdl_upgradable attribute is properly
  propagated for underlying tables of view.
sql/table.cc:
  Added auxiliary alloc_mdl_locks() function for allocating metadata
  lock request objects for all elements of table list.
sql/table.h:
  TABLE_SHARE:
    Got rid of unused members. Introduced members for storing lists
    of used and unused TABLE objects for this share.
  TABLE:
    Added members for linking TABLE objects into per-share lists of
    used and unused TABLE instances. Added member for holding
    pointer to metadata lock for this table.
  TABLE_LIST:
    Replaced boolean TABLE_LIST::create member with enum
    open_table_type member.  This allows easily handle situation in
    which instead of opening the table we want only to take
    exclusive meta-data lock on it (we need this in order to handle
    ALTER VIEW and CREATE VIEW statements).
    Introduced new mdl_upgradable member for marking elements of
    table list for which we need to take upgradable shared metadata
    lock instead of plain shared metadata lock.  Added pointer for
    holding pointer to MDL_LOCK for the table.
  Added auxiliary alloc_mdl_locks() function for allocating metadata
  lock requests objects for all elements of table list.  Added
  auxiliary set_all_mdl_upgradable() function for marking all
  elements in table list as requiring upgradable metadata locks.
storage/myisammrg/ha_myisammrg.cc:
  Allocate MDL_LOCK objects for underlying tables of MERGE table.
  To be reworked once Ingo pushes his patch for WL4144.

The problem is that the server could crash when attempting
to access a non-conformant proc system table. One such case
was a crash when invoking stored procedure related statements
on a 5.1 server with a proc system table in the 5.0 format.

The solution is to validate the proc system table format
before attempts to access it are made. If the table is not
in the format that the server expects, a message is written
to the error log and the statement that caused the table to
be accessed fails.

mysql-test/r/sp-destruct.result:
  Add test case result for Bug#41726
mysql-test/t/sp-destruct.test:
  Add test case for Bug#41726
sql/event_db_repository.cc:
  Update code to use new structures.
sql/sp.cc:
  Describe the proc table format and use it to validate when
  opening a instance of the table.
  Add a check to insure that a error message is written to
  the error log only once.
sql/sql_acl.cc:
  Remove unused variable and use new structure.
sql/sql_acl.h:
  Export field definition.
sql/table.cc:
  Accept the field count and definition in a single structure.
sql/table.h:
  Combine the field count and definition in a single structure.
  Transform function into a class in order to support different
  ways of reporting a error.
  Add a pointer cache to TABLE_SHARE.

Cleaning up warnings not present in 5.0.

General overview:
The logic for switching to row format when binlog_format=MIXED had
numerous flaws. The underlying problem was the lack of a consistent
architecture.
General purpose of this changeset:
This changeset introduces an architecture for switching to row format
when binlog_format=MIXED. It enforces the architecture where it has
to. It leaves some bugs to be fixed later. It adds extensive tests to
verify that unsafe statements work as expected and that appropriate
errors are produced by problems with the selection of binlog format.
It was not practical to split this into smaller pieces of work.

Problem 1:
To determine the logging mode, the code has to take several parameters
into account (namely: (1) the value of binlog_format; (2) the
capabilities of the engines; (3) the type of the current statement:
normal, unsafe, or row injection). These parameters may conflict in
several ways, namely:
 - binlog_format=STATEMENT for a row injection
 - binlog_format=STATEMENT for an unsafe statement
 - binlog_format=STATEMENT for an engine only supporting row logging
 - binlog_format=ROW for an engine only supporting statement logging
 - statement is unsafe and engine does not support row logging
 - row injection in a table that does not support statement logging
 - statement modifies one table that does not support row logging and
   one that does not support statement logging
Several of these conflicts were not detected, or were detected with
an inappropriate error message. The problem of BUG#39934 was that no
appropriate error message was written for the case when an engine
only supporting row logging executed a row injection with
binlog_format=ROW. However, all above cases must be handled.
Fix 1:
Introduce new error codes (sql/share/errmsg.txt). Ensure that all
conditions are detected and handled in decide_logging_format()

Problem 2:
The binlog format shall be determined once per statement, in
decide_logging_format(). It shall not be changed before or after that.
Before decide_logging_format() is called, all information necessary to
determine the logging format must be available. This principle ensures
that all unsafe statements are handled in a consistent way.
However, this principle is not followed:
thd->set_current_stmt_binlog_row_based_if_mixed() is called in several
places, including from code executing UPDATE..LIMIT,
INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and
SET @@binlog_format. After Problem 1 was fixed, that caused
inconsistencies where these unsafe statements would not print the
appropriate warnings or errors for some of the conflicts.
Fix 2:
Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from
code executed after decide_logging_format(). Compensate by calling the
set_current_stmt_unsafe() at parse time. This way, all unsafe statements
are detected by decide_logging_format().

Problem 3:
INSERT DELAYED is not unsafe: it is logged in statement format even if
binlog_format=MIXED, and no warning is printed even if
binlog_format=STATEMENT. This is BUG#45825.
Fix 3:
Made INSERT DELAYED set itself to unsafe at parse time. This allows
decide_logging_format() to detect that a warning should be printed or
the binlog_format changed.

Problem 4:
LIMIT clause were not marked as unsafe when executed inside stored
functions/triggers/views/prepared statements. This is
BUG#45785.
Fix 4:
Make statements containing the LIMIT clause marked as unsafe at
parse time, instead of at execution time. This allows propagating
unsafe-ness to the view.


mysql-test/extra/rpl_tests/create_recursive_construct.inc:
  Added auxiliary file used by binlog_unsafe.test to create and
  execute recursive constructs
  (functions/procedures/triggers/views/prepared statements).
mysql-test/extra/rpl_tests/rpl_foreign_key.test:
  removed unnecessary set @@session.binlog_format
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
  Filter out table id from table map events in binlog listing.
  Got rid of $binlog_format_statement.
mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test:
  disable warnings around call to unsafe procedure
mysql-test/include/rpl_udf.inc:
  Disabled warnings for code that generates warnings
  for some binlog formats. That would otherwise cause
  inconsistencies in the result file.
mysql-test/r/mysqldump.result:
  Views are now unsafe if they contain a LIMIT clause.
  That fixed BUG#45831. Due to BUG#45832, a warning is
  printed for the CREATE VIEW statement.
mysql-test/r/sp_trans.result:
  Unsafe statements in stored procedures did not give a warning if
  binlog_format=statement. This is BUG#45824. Now they do, so this
  result file gets a new warning.
mysql-test/suite/binlog/r/binlog_multi_engine.result:
  Error message changed.
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
  INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT.
  That was BUG#45825. Now there is a warning, so result file needs to be
  updated.
mysql-test/suite/binlog/r/binlog_stm_ps.result:
  Changed error message.
mysql-test/suite/binlog/r/binlog_unsafe.result:
  updated result file:
   - error message changed
   - added test for most combinations of unsafe constructs invoked
     from recursive constructs
   - INSERT DELAYED now gives a warning (because BUG#45826 is fixed)
   - INSERT..SELECT..LIMIT now gives a warning from inside recursive
     constructs (because BUG#45785 was fixed)
   - When a recursive construct (e.g., stored proc or function)
     contains more than one statement, at least one of which is
     unsafe, then all statements in the recursive construct give
     warnings. This is a new bug introduced by this changeset.
     It will be addressed in a post-push fix.
mysql-test/suite/binlog/t/binlog_innodb.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
mysql-test/suite/binlog/t/binlog_multi_engine.test:
  The error code has changed for statements where more than one
  engine is involved and one of them is self-logging.
mysql-test/suite/binlog/t/binlog_unsafe-master.opt:
  Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra
  flag in the .opt file.
mysql-test/suite/binlog/t/binlog_unsafe.test:
   - Clarified comment.
   - Rewrote first part of test. Now it tests not only unsafe variables
     and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT,
     INSERT DELAYED, insert into two autoinc columns, use of UDF's, and
     access to log tables in the mysql database.
     Also, in addition to functions, procedures, triggers, and prepared
     statements, it now also tests views; and it constructs recursive
     calls in two levels by combining these recursive constructs.
     Part of the logic is in extra/rpl_tests/create_recursive_construct.inc.
   - added tests for all special system variables that should not be unsafe.
   - added specific tests for BUG#45785 and BUG#45825

  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals
  the second half of the old rpl_found_rows.result, with the following
  modifications:
   - minor formatting changes
   - additional initialization
mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.

  Got rid of unnecessary explicit setting of binlog format.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - warning is now issued for unsafe statements inside procedures
     (since BUG#45824 is fixed)
   - second half of file is moved to rpl_mix_found_rows.result

  error message changed
mysql-test/suite/rpl/r/rpl_temporary_errors.result:
  updated result file
mysql-test/suite/rpl/r/rpl_udf.result:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl/t/rpl_bug31076.test:
  Test is only valid in mixed or row mode since it generates row events.
mysql-test/suite/rpl/t/rpl_events.test:
  Removed explicit set of binlog_format and removed duplicate testing.
  Instead, we rely on the test system to try all binlog formats.
mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_idempotency-slave.opt:
  Removed .opt file to avoid server restarts.
mysql-test/suite/rpl/t/rpl_idempotency.test:
  - Moved out row-only tests to a new test file, rpl_row_idempotency.test.
    rpl_idempotency now only contains tests that execute in all
    binlog_formats.
  - While I was here, also removed .opt file to avoid server restarts.
    The slave_exec_mode is now set inside the test instead.
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file
  contains the second half of the original rpl_found_rows.test with the
  follwing changes:
   - initialization
   - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc
   - minor formatting changes
mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test:
  Test cannot execute in statement mode, since we no longer
  switch to row format when binlog_format=statement.
  Enforced mixed mode throughout the test.
mysql-test/suite/rpl/t/rpl_row_idempotency.test:
  Moved the second half of rpl_idempotency.test, which only
  executed in row mode, to this new file. We now rely on the
  test system to set binlog format.
mysql-test/suite/rpl/t/rpl_row_insert_delayed.test:
   - Got rid of unnecessary explicit setting of binlog format.
   - extra/rpl_tests/rpl_insert_delayed.test does not need the
     $binlog_format_statement variable any more, so that was
     removed.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode.
mysql-test/suite/rpl/t/rpl_stm_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - added have_binlog_format_statement and removed SET BINLOG_FORMAT.
   - second half of file is moved to rpl_mix_found_rows.test
   - added cleanup code
mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode on slave.
mysql-test/suite/rpl/t/rpl_temporary_errors.test:
  Removed explicit set of binlog format. Instead, the test now only
  executes in row mode.
mysql-test/suite/rpl/t/rpl_udf.test:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl_ndb/combinations:
  Added combinations file for rpl_ndb.
mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result:
  new result file
mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result:
  updated result file
mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_basic.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.

  new option file
mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors-slave.opt:
  new option file
mysql-test/suite/rpl_ndb/t/rpl_ndb_binlog_format_errors.test:
  New test case to verify all errors and warnings generated by
  decide_logging_format.
mysql-test/suite/rpl_ndb/t/rpl_ndb_blob.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_blob2.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_circular.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_circular_simplex.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
  While I was here, also made the test clean up after itself.

  test was changed to only execute in mixed and row mode.
mysql-test/t/partition_innodb_stmt.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
sql/event_db_repository.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/events.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/ha_ndbcluster_binlog.cc:
  reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog
  thread any more. Instead, the ndb_binlog thread now forces row mode both
  initially and just after calling mysql_parse.  (mysql_parse() is the only
  place where reset_current_stmt_binlog_row_based() may be called from
  the ndb_binlog thread, so these are the only two places that need to
  change.)
sql/ha_partition.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/handler.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/item_create.cc:
  Added DBUG_ENTER to some functions, to be able to trace when
  set_stmt_unsafe is called.
sql/log.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/log_event.cc:
   - Moved logic for changing to row format out of do_apply_event (and into
     decide_logging_format).
   - Added @todo comment for post-push cleanup.
sql/log_event_old.cc:
  Move logic for changing to row format out of do_apply_event (and into
  decide_logging_format).
sql/mysql_priv.h:
  Make decide_logging_format() a member of the THD class, for two reasons:
   - It is natural from an object-oriented perspective.
   - decide_logging_format() needs to access private members of THD
     (specifically, the new binlog_warning_flags field).
sql/rpl_injector.cc:
  Removed call to set_current_stmt_binlog_row_based().
  From now on, only decide_logging_fromat is allowed to modify
  current_stmt_binlog_row_based. This call is from the ndb_binlog
  thread, mostly executing code in ha_ndbcluster_binlog.cc.
  This call can be safely removed, because:
   - current_stmt_binlog_row_based is initialized for the ndb_binlog
     thread's THD object when the THD object is created. So we're
     not going to read uninitialized memory.
   - The behavior of ndb_binlog thread does not use the state of the
     current_stmt_binlog_row_based. It is conceivable that the
     ndb_binlog thread would rely on the current_stmt_binlog_format
     in two situations:
      (1) when it calls mysql_parse;
      (2) when it calls THD::binlog_query.
     In case (1), it always clears THD::options&OPTION_BIN_LOG (because
     run_query() in ha_ndbcluster_binlog.cc is only called with
     disable_binlogging = TRUE).
     In case (2), it always uses qtype=STMT_QUERY_TYPE.
sql/set_var.cc:
  Added @todo comment for post-push cleanup.
sql/share/errmsg.txt:
  Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT.
sql/sp.cc:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sp_head.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sp_head.h:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_acl.cc:
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sql_base.cc:
   - Made decide_logging_format take care of all logic for deciding the
     logging format, and for determining the related warnings and errors.
     See comment above decide_logging_format for details.
   - Made decide_logging_format a member function of THD, since it needs
     to access private members of THD and since its purpose is to update
     the state of a THD object.
   - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_class.cc:
  - Moved logic for determining unsafe warnings away from THD::binlog_query
    (and into decide_logging_format()). Now, it works like this:
    1. decide_logging_format detects that the current statement shall
       produce a warning, if it ever makes it to the binlog
    2. decide_logging_format sets a flag of THD::binlog_warning_flags.
    3. THD::binlog_query reads the flag. If the flag is set, it generates
       a warning.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_class.h:
  - Added THD::binlog_warning_flags (see sql_class.cc for explanation).
  - Made decide_logging_format() and reset_for_next_command() member
    functions of THD (instead of standalone functions). This was needed
    for two reasons: (1) the functions need to access the private member
    THD::binlog_warning_flags; (2) the purpose of these functions is to
    update the staet of a THD object, so from an object-oriented point
    of view they should be member functions.
  - Encapsulated current_stmt_binlog_row_based, so it is now private and
    can only be accessed from a member function. Also changed the
    data type to an enumeration instead of a bool.
  - Removed MYSQL_QUERY_TYPE, because it was equivalent to
    STMT_QUERY_TYPE anyways.
  - When reset_current_stmt_binlog_row_based was called from the
    ndb_binlog thread, it would behave as a no-op. This special
    case has been removed, and the behavior of
    reset_current_stmt_binlog_row_based does not depend on which thread
    calls it any more. The special case did not serve any purpose,
    since the ndb binlog thread did not take the
    current_stmt_binlog_row_based flag into account anyways.
sql/sql_delete.cc:
  - Moved logic for setting row format for DELETE..LIMIT away from
    mysql_prepare_delete.
    (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
    and rely on decide_logging_format() (sql_class.cc) to set row format.)
    This is part of the fix for BUG#45831.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_insert.cc:
   - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and
     thd->set_current_stmt_binlog_row_based_if_mixed() from
     handle_delayed_insert(). The calls are unnecessary because they
     have already been made; they were made in the constructor of
     the `di' object.
   - Since decide_logging_format() is now a member function of THD, code
     that calls decide_logging_format() had to be updated.
   - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is
     called.
   - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from
     mysql_insert_select_prepare() (and into decide_logging_format).
     This is part of the fix for BUG#45831.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_lex.h:
   - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag.
     This was necessary so that a statement can identify itself as a row
     injection.
   - Added appropriate setter and getter functions for the new flag.
   - Added or clarified some comments.
   - Added DBUG_ENTER()
sql/sql_load.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_parse.cc:
   - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags.
   - Since thd->binlog_warning_flags is private, it must be set in a
     member function of THD. Hence, moved the body of
     mysql_reset_thd_for_next_command() to the new member function
     THD::reset_thd_for_next_command(), and made
     mysql_reset_thd_for_next_command() call
     THD::reset_thd_for_next_command().
   - Removed confusing comment.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_repl.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_table.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_udf.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_update.cc:
  Moved logic for setting row format for UPDATE..LIMIT away from
  mysql_prepare_update.
  (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
  and rely on decide_logging_format() (sql_class.cc) to set row format.)
  This is part of the fix for BUG#45831.
sql/sql_yacc.yy:
  Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and
  DELETE..LIMIT mark themselves as unsafe at parse time (instead
  of at execution time).
  This is part of the fixes BUG#45831 and BUG#45825.
storage/example/ha_example.cc:
  Made exampledb accept inserts. This was needed by the new test case
  rpl_ndb_binlog_format_errors, because it needs an engine that
  is statement-only (and accepts inserts).
storage/example/ha_example.h:
  Made exampledb a statement-only engine instead of a row-only engine.
  No existing test relied exampledb's row-only capabilities. The new
  test case rpl_ndb_binlog_format_errors needs an engine that is
  statement-only.
storage/innobase/handler/ha_innodb.cc:
  - Changed error error code and message given by innodb when 
    binlog_format=STATEMENT and transaction isolation level is
    READ COMMITTED or READ UNCOMMITTED.
  - While I was here, also simplified the condition for
    checking when to give the error.

since Oct 1st

If [NOT] PRESERVE was not given, parser always defaulted to NOT
PRESERVE, making it impossible for the "not given = no change"
rule to work in ALTER EVENT. Leaving out the PRESERVE-clause
defaults to NOT PRESERVE on CREATE now, and to "no change" in
ALTER.

mysql-test/r/events_2.result:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
mysql-test/t/events_2.test:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
sql/event_db_repository.cc:
  If ALTER EVENT was given no PRESERVE-clause (meaning "no change"),
  we don't know the previous PRESERVE-setting by the time we check
  the parse-data. If ALTER EVENT was given dates that are in the past,
  we don't know how to react, lacking the PRESERVE-setting. Heal this
  by running the check later when we have actually read the previous
  EVENT-data.
sql/event_parse_data.cc:
  Change default for ON COMPLETION to indicate, "not specified."
  Also defer throwing errors when ALTER EVENT is given dates in
  the past but not PRESERVE-clause until we know the previous
  PRESERVE-value.
sql/event_parse_data.h:
  Add third state for ON COMPLETION [NOT] PRESERVE (preserve,
  don't, not specified).
  
  Make check_dates() public so we can defer this check until
  deeper in the callstack where we have all the required data.
sql/sql_yacc.yy:
  If CREATE EVENT is not given ON COMPLETION [NOT] PRESERVE,
  we default to NOT, as per the docs.

The problem is that one can not create a stored routine if sql_mode
contains NO_ENGINE_SUBSTITUTION or PAD_CHAR_TO_FULL_LENGTH. Also when
a event is created, the mode is silently lost if sql_mode contains one
of the aforementioned.  This was happening because the table definitions
which stored sql_mode values weren't being updated to accept new values
of sql_mode.

The solution is to update, in a backwards compatible manner, the various
table definitions (columns) that store the sql_mode value to take into
account the new possible values. One incompatible change is that if a event
that is being created can't be stored to the mysql.event table, an error
will be raised.

The tests case also ensure that new SQL modes will be added to the mysql.proc
and mysql.event tables, otherwise the tests will fail.

If a stored function that contains a drop temporary table statement
is invoked by a create temporary table of the same name may cause
a server crash. The problem is that when dropping a table no check
is done to ensure that table is not being used by some outer query
(or outer statement), potentially leaving the outer query with a
reference to a stale (freed) table.

The solution is when dropping a temporary table, always check if
the table is being used by some outer statement as a temporary
table can be dropped inside stored procedures.

The check is performed by looking at the TABLE::query_id value for
temporary tables. To simplify this check and to solve a bug related
to handling of temporary tables in prelocked mode, this patch changes
the way in which this member is used to track the fact that table is
used/unused. Now we ensure that TABLE::query_id is zero for unused
temporary tables (which means that all temporary tables which were
used by a statement should be marked as free for reuse after it's
execution has been completed).

sql/sql_base.cc:
  Changed the approach to distinguishing currently unused temporary tables.
  Now we ensure that such tables always have TABLE::query_id set to 0 and
  use this fact to perform checks during opening and dropping of temporary
  tables. This means that we have to call close_thread_tables() even for
  statements which use only temporary tables. To make this call cheaper,
  we re-factored close_thread_tables() to not take LOCK_open unless there
  are open base tables.
sql/sql_handler.cc:
  Properly close temporary tables associated with a handler.
sql/sql_insert.cc:
  close_temporary_table is now merged into drop_temporary_table.
sql/sql_parse.cc:
  Now the condition doesn't cover all cases because close_thread_tables()
  must be called even for statements that use only temporary tables.
sql/sql_table.cc:
  Use drop_temporary_table which perform checks to verify if
  the table is not being used. Error path problem is due to
  a handler tables issue and is going to be addressed in bug
  31397.
sql/table.h:
  Rename previously unused clear_query_id and document the usage of
  query_id and open_by_handler.

There actually were several problems here:
  - WRITE-lock is required to load events from the mysql.event table,
    but in the read-only mode an ordinary user can not acquire it;
  - Security_context::master_access attribute was not properly
    initialized in Security_context::init(), which led to differences
    in behavior with and without debug configure options.
  - if the server failed to load events from mysql.event, it forgot to
    close the mysql.event table, that led to the coredump, described
    in the bug report.

The patch is to fix all these problems:
  - Use the super-user to acquire WRITE-lock on the mysql.even table;
  - The WRITE-lock is acquired by the event scheduler in two cases:
    - on initial loading of events from the database;
    - when an event has been executed, so its attributes should
      be updated.
    Other cases when WRITE-lock is needed for the mysql.event table
    happen under the user account. So, nothing should be changed there
    for the read-only mode. The user is able to create/update/drop
    an event only if he is a super-user.
  - Initialize Security_context::master_access;
  - Close the mysql.event table in case something went wrong.

sql/event_data_objects.cc:
  When the worker thread is going to drop event after the execution
  we should do it under the super-user privileges in order to be able
  to lock the mysql.event table for writing in the read-only mode.
  
  This is a system operation, where user SQL can not be executed.
  So, there is no risk in compromising security by dropping an event
  under the super-user privileges.
sql/event_db_repository.cc:
  1. Close tables if something went wrong in simple_open_n_lock_tables();
  2. As soon as the system event scheduler thread is running under
     the super-user privileges, we should always be able to acquire
     WRITE-lock on the mysql.event table. However, let's have an assert
     to check this.
sql/event_scheduler.cc:
  Run the system event scheduler thread under the super-user privileges.
  In particular, this is needed to be able to lock the mysql.event table
  for writing when the server is running in the read-only mode.
  
  The event scheduler executes only system operations and does not
  execute user SQL (this is what the worker threads for). So, there

Creating an EVENT to be executed at a time close to the end of the allowed
range (2038.01.19 03:14:07 UTC) would cause the server to crash. The
expected behavior is to accept all calendar times within the interval and
reject all other values without crashing.

This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call.
This function was broken because it invoked the internal function 'sec_to_epoch'
without respecting the restrictions on the function parameters (and this caused
assertion failure). It also was used as a reverse function to
Time_zone_utc::gmt_sec_to_TIME which it isn't.

  the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used
  by events code to store information about event execution time.

  - BUG#11986: Stored routines and triggers can fail if the code
    has a non-ascii symbol
  - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars
  - BUG#19443: INFORMATION_SCHEMA does not support charsets properly
  - BUG#21249: Character set of SP-var can be ignored
  - BUG#25212: Character set of string constant is ignored (stored routines)
  - BUG#25221: Character set of string constant is ignored (triggers)

There were a few general problems that caused these bugs:
1. Character set information of the original (definition) query for views,
   triggers, stored routines and events was lost.
2. mysqldump output query in client character set, which can be
   inappropriate to encode definition-query.
3. INFORMATION_SCHEMA used strings with mixed encodings to display object
   definition;

1. No query-definition-character set.

In order to compile query into execution code, some extra data (such as
environment variables or the database character set) is used. The problem
here was that this context was not preserved. So, on the next load it can
differ from the original one, thus the result will be different.

The context contains the following data:
  - client character set;
  - connection collation (character set and collation);
  - collation of the owner database;

The fix is to store this context and use it each time we parse (compile)
and execute the object (stored routine, trigger, ...).

2. Wrong mysqldump-output.

The original query can contain several encodings (by means of character set
introducers). The problem here was that we tried to convert original query
to the mysqldump-client character set.

Moreover, we stored queries in different character sets for different
objects (views, for one, used UTF8, triggers used original character set).

The solution is
  - to store definition queries in the original character set;
  - to change SHOW CREATE statement to output definition query in the
    binary character set (i.e. without any conversion);
  - introduce SHOW CREATE TRIGGER statement;
  - to dump special statements to switch the context to the original one
    before dumping and restore it afterwards.

Note, in order to preserve the database collation at the creation time,
additional ALTER DATABASE might be used (to temporary switch the database
collation back to the original value). In this case, ALTER DATABASE
privilege will be required. This is a backward-incompatible change.

3. INFORMATION_SCHEMA showed non-UTF8 strings

The fix is to generate UTF8-query during the parsing, store it in the object
and show it in the INFORMATION_SCHEMA.

Basically, the idea is to create a copy of the original query convert it to
UTF8. Character set introducers are removed and all text literals are
converted to UTF8.

This UTF8 query is intended to provide user-readable output. It must not be
used to recreate the object.  Specialized SHOW CREATE statements should be
used for this.

The reason for this limitation is the following: the original query can
contain symbols from several character sets (by means of character set
introducers).

Example:

  - original query:
    CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1;

  - UTF8 query (for INFORMATION_SCHEMA):
    CREATE VIEW v1 AS SELECT 'Hello' AS c1;

when there are no up-to-date system tables to support it:
 - initialize the scheduler before reporting "Ready for connections".
   This ensures that warnings, if any, are printed before "Ready for
   connections", and this message is not mangled.
 - do not abort the scheduler if there are no system tables
 - check the tables once at start up, remember the status and disable
   the scheduler if the tables are not up to date.
   If one attempts to use the scheduler with bad tables,
   issue an error message.
 - clean up the behaviour of the module under LOCK TABLES and pre-locking
   mode
 - make sure implicit commit of Events DDL works as expected.
 - add more tests

  Move check_system_tables from events.cc to this file
sql/event_db_repository.h:
  Cleanup declarations (remove unused ones, change return type to bool
  from int).
sql/event_queue.cc:
  Update to adapt to the new start up scheme of the Event Scheduler.
sql/event_queue.h:
  Cleanup declarations.
sql/event_scheduler.cc:
  Make all the error messages uniform:
  [SEVERITY] Event Scheduler: [user][schema.event] message
  Using append_identifier for error logging was an overkill - we may 
  need it only if the system character set may have NUL (null character)
  as part of a valid identifier, this is currently never the case, 
  whereas additional quoting did not look nice in the log.
sql/event_scheduler.h:
  Cleanup the headers.
sql/events.cc:
  Use a different start up procedure of Event Scheduler:
  - at start up, try to check the system tables first.
  If they are not up-to-date, disable the scheduler.
  - try to load all the active events. In case of a load error, abort
  start up.
  - do not parse an event on start up. Parsing only gives some information
  about event validity, but far not all.
  Consolidate the business logic of Events DDL in this module.
  Now opt_event_scheduler may change after start up and thus is protected
  by LOCK_event_metadata mutex.
sql/events.h:
  Use all-static-data-members approach to implement Singleton pattern.
sql/mysqld.cc:
  New invocation scheme of Events. Move some logic to events.cc.
  Initialize the scheduler before reporting "Ready for connections".
sql/set_var.cc:
  Clean up sys_var_thd_sql_mode::symbolic_mode_representation
  to work with a LEX_STRING.
  Move more logic related to @@events_scheduler global variable to Events
  module.
sql/set_var.h:
  Update declarations.
sql/share/errmsg.txt:
  If someone tampered with mysql.event table after the server has
  started we no longer give him/her a complete report what was actually 
  broken. Do not send the user to look at the error log in such case,
  as there is nothing there (check_table_intact is not executed).
sql/sp_head.cc:
  Update to a new declaration of 
  sys_var_thd_sql_mode::symbolic_mode_representation
sql/sql_db.cc:
  New invocation scheme of Events module.
sql/sql_parse.cc:
  Move more logic to Events module. Make sure that we are consistent
  in the way access rights are checked for Events DDL: always
  after committing the current transaction and checking the system tables.
sql/sql_show.cc:
  Update to the new declarations of 
  sys_var_thd_sql_mode::symbolic_mode_representation
sql/sql_test.cc:
  New invocation scheme of events.
sql/table.cc:
  mysql.event is a system table.
  Update check_table_intact to be concurrent, more verbose, and less smart.
sql/table.h:
  Add a helper method.
mysql-test/r/events_trans.result:
  New BitKeeper file ``mysql-test/r/events_trans.result''
mysql-test/t/events_trans.test:
  New BitKeeper file ``mysql-test/t/events_trans.test'':
  test cases for Event Scheduler that require a transactional
  storage engine.

BUG#26429: SHOW CREATE EVENT is incorrect for an event that
           STARTS NOW()
BUG#26431: Impossible to re-create an event from backup if its
           STARTS clause is in the past
WL#3698: Events: execution in local time zone

The problem was that local times specified by the user in AT, STARTS
and ENDS of CREATE EVENT/ALTER EVENT statement were converted to UTC,
and the original time zone was forgotten.  This way, event scheduler
couldn't honor Daylight Saving Time shifts, and times shown to the
user were also in UTC.  Additionally, CREATE EVENT didn't allow times
in the past, thus preventing straightforward event restoration from
old backups.

This patch reworks event scheduler time computations, performing them
in the time zone associated with the event.  Also it allows times to
be in the past.

The patch adds time_zone column to mysql.event table.

NOTE: The patch is almost final, but the bug#9953 should be pushed
first.


client/mysqldump.c:
  Before every CREATE EVENT, output its time zone.
mysql-test/include/wait_condition.inc:
  Add optional $wait_timeout parameter.
mysql-test/lib/init_db.sql:
  Add time_zone column.
mysql-test/r/events.result:

mysql-test/t/events.test:
  Remove STARTS from the result, as it depends on current time.
mysql-test/t/events_bugs.test:
  Time in the past is no longer an error.
mysql-test/t/events_restart_phase1.test:
  Fill new column 'time_zone' in mysql.event.
mysql-test/t/events_scheduling.test:
  Cleanup: disable event scheduler.
scripts/mysql_create_system_tables.sh:
  Add new column 'time_zone' to mysql.event.
scripts/mysql_fix_privilege_tables.sql:
  Add new column 'time_zone' to mysql.event.
sql/event_data_objects.cc:
  The essence of the change is the following:
   - for internal times use my_time_t instead of TIME.  Assignment and
     comparison is done now on plain numbers.
   - in init_execute_at(), init_starts(), init_ends() convert given time
     to number of seconds since Epoch (aka Unix time, in UTC).
   - handle time_zone field loading and storing.
   - in get_next_time(), Unix time is converted back to event time zone,
     interval is added, and the result is converted to UTC again.
   - fix Event_timed::get_create_event() to report STARTS and ENDS.
   - before executing the event body we set thread time zone to the
     event time zone.
sql/event_data_objects.h:
  Add time_zone member to Event_basic class.
  
  Store internal times in my_time_t (number of seconds since Epoch),
  rather than in broken down TIME structure.
sql/event_db_repository.cc:
  Add time_zone column handling.
  
  Give a warning and do not create an event if its execution time is in
  the past, and ON COMPLETION NOT PRESERVE is set, because such an event
  should be dropped by that time.  Also, do not allow ALTER EVENT to
  set execution time in the past when ON COMPLETION NOT PRESERVE is set.
sql/event_db_repository.h:
  Add enum member for new time zone column.
sql/event_queue.cc:
  Replace handling of broken down times with simple handling of
  my_time_t.
sql/event_queue.h:
  Store internal times in my_time_t (number of seconds since Epoch),
  rather than in broken down TIME structure.
sql/event_scheduler.cc:
  Add TODO comment.
sql/events.cc:
  Send time_zone column for SHOW CREATE EVENT.
sql/share/errmsg.txt:
  Update error message, and add two more errors.
sql/sql_show.cc:
  Add TIME_ZONE column to the output of SHOW EVENTS.

This changeset adds replication of events and user-defined functions. 
There are several bug reports involved in this change:

BUG#16421, BUG#17857, BUG#20384:
This patch modifies the mysql.events table to permit the addition of
another enum value for the status column. The column now has values
of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
SLAVESIDE_DISABLED is set on the slave during replication of events.
This enables users to determine which events werereplicated from the 
master and to later enable them if they promote the slave to a master.
The CREATE, ALTER, and DROP statements are binlogged.
A new test was added for replication of events (rpl_events).

BUG#17671:
This patch modifies the code to permit logging of user-defined functions.
Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error 
message to be displayed should a replicated user-defined function not be
found in the loadable library or if the library is missing from the
slave.The CREATE andDROP statements are binlogged. A new test was added 
for replication of user-defined functions (rpl_udf). 

The patch also adds a new column to the mysql.event table named
'originator' that is used to store the server_id of the server that
the event originated on. This enables users to promote a slave to a 
master and later return the promoted slave to a slave and disable the
replicated events.


mysql-test/lib/init_db.sql:
  WL#3629 - Replication of Invocation and Invoked Feature
  This patch adds the SLAVESIDE_DISABLED to the list of enumerated 
  values for the mysql.event table.
  
  This patch adds the column 'originator' to the mysql.event table.
mysql-test/r/events.result:
  WL#3629 - Replication of Invocation and Invoked Feature
  This patch adds the 'originator' column to the events test results.
  This was necessary to ensure the manual insert into mysql.event table 
  succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_grant.result:
  WL#3629 - Replication of Invocation and Invoked Feature
  This patch adds the 'originator' column to the events_grant test results.
  This was necessary to ensure the manual insert into mysql.event table 
  succeeds because the originator column is set to NOT NULL.
mysql-test/r/events_restart_phase1.result:
  WL#3629 - Replication of Invocation and Invoked Feature
  This patch adds the 'originator' column to the events_restart_phase1
  test results. This was necessary to ensure the manual insert into 
  mysql.event table succeeds because the originator column is set to 
  NOT NULL.
mysql-test/r/system_mysql_db.result:
  WL#3629 - Replication of Invocation and Invoked Feature
  This patch adds the SLAVESIDE_DISABLED to the list of enumerated 
  values for the mysql.event table.

  results.
mysql-test/t/events.test:
  WL#3629 - Replication of Invocation and Invoked Feature
