d66157e30f An assertion added (transaction must be re-enabled before end of
top-level statement) and fixes for the bugs it finds.
Fix for non-serious Valgrind warning.


sql/sql_insert.cc:
  When CREATE TABLE IF NOT EXISTS finds the table already exists,
  'table' is the existing table. So if that table is temporary we don't
  re-enable transactions which is a bug.
sql/sql_parse.cc:
  verify that at the end of each top-statement transactions have
  been re-enabled. Does not apply to substatements (consider
  CREATE TABLE t1 SELECT stored_func() : the substatements inside
  stored_func() run with transaction disabled).
  I am not putting the assertion into ha_external_lock(F_UNLCK) because
  performance schema tables get closed in the middle of a statement
  sometimes while transaction is disabled.
sql/sql_table.cc:
  copy_data_between_tables() forgot to clean-up several things in error
  conditions (ha_enable_transaction(), free-ing 'copy', etc) as found
  by the assertion added to sql_parse.cc.

18bc7b695a WL#3072 - Maria Recovery
* to honour WAL we now force the whole log when flushing a bitmap page.
* ability to intentionally crash in various places for recovery testing
* bugfix (dirty pages list found in checkpoint record was ignored)
* smaller checkpoint record
* misc small cleanups and comments


mysql-test/include/maria_empty_logs.inc:
  maria-purge.test creates ~11 logs, remove them all
mysql-test/r/maria-recovery-bitmap.result:
  result is good; without the _ma_bitmap_get_log_address() call,
  we got
  check   error   Bitmap at 0 has pages reserved outside of data file length
mysql-test/r/maria-recovery.result:
  result update
mysql-test/t/maria-recovery-bitmap.test:
  enable test of "bitmap-flush should flush whole log otherwise
  corrupted data file (bitmap ahead of data pages)".
mysql-test/t/maria-recovery.test:
  test of checkpoint
sql/sql_table.cc:
  comment
storage/maria/ha_maria.cc:
  _ma_reenable_logging_for_table() now includes file->trn=0.
  At the end of repair() we don't need to re-enable logging, it is
  done already by caller (like copy_data_between_tables()); it sounds
  strange that this function could decide to re-enable, it should be
  up to caller who knows what other operations it plans. Removing this
  line led to assertion failure in maria_lock_database(F_UNLCK), fixed
  by removing the assertion: maria_lock_database()
  is here called in a context where F_UNLCK does not make the
  table visible to others so assertion is excessive, and external_lock()
  is already designed to honour the asserted condition.
  Ability to crash at the end of bulk insert when indices
  have been enabled.
storage/maria/ma_bitmap.c:
  Better use pagecache_file_init() than set pagecache callbacks directly;
  and a new function to set those callbacks for bitmap so that we can
  reuse it.
  _ma_bitmap_get_log_address() is a pagecache get_log_address callback
  which causes the whole log to be flushed when a bitmap page
  is flushed by the page cache. This was required by WAL.
storage/maria/ma_blockrec.c:
  get_log_address pagecache callback for data (non bitmap) pages:
  just reads the LSN from the page's content, like was hard-coded
  before in ma_pagecache.c.
storage/maria/ma_blockrec.h:
  functions which need to be exported
storage/maria/ma_check.c:
  create_new_data_handle() can be static.
  Ability to crash after rebuilding the index in OPTIMIZE,
  in REPAIR. my_lock() implemented already.
storage/maria/ma_checkpoint.c:
  As MARIA_SHARE* is now accessible to pagecache_collect_changed_blocks_LSN(),
  we don't need to store kfile/dfile descriptors in checkpoint record,
  2-byte-id of the table plus one byte to say if this is data or index
  file is enough. So we go from 4+4 bytes per table down to 2+1.
storage/maria/ma_commit.c:
  removing duplicate functions (see _ma_tmp_disable_logging_for_table())
storage/maria/ma_extra.c:
  Monty fixed
storage/maria/ma_key_recover.c:
  comment
storage/maria/ma_locking.c:
  Sometimes other code does funny things with maria_lock_database(),
  like ha_maria::repair() calling it at start and end without going
  through ha_maria::external_lock(). So it happens that maria_lock_database()
  is called with now_transactional!=born_transactional.
storage/maria/ma_loghandler.c:
  update to new prototype
storage/maria/ma_open.c:
  set_data|index_pagecache_callbacks() need to be exported as
  they are now called when disabling/enabling transactionality.
storage/maria/ma_pagecache.c:
  Removing PAGE_LSN_OFFSET, as much of the code relies on it being
  0 anyway (let's not give impression we can just change this constant).
  When flushing a page to disk, call the get_log_address callback to
  know up to which LSN the log should be flushed.
  As we now can access MARIA_SHARE* we can know share->id and store
  it into the checkpoint record; we thus go from 4 bytes per dirty page
  to 2+1.
storage/maria/ma_pagecache.h:
  get_log_address callback
storage/maria/ma_panic.c:
  No reason to reset pagecache callbacks in HA_PANIC_READ:
  all we do is reopen files if they were closed; callbacks should
  be in place already as 'info' exists; we just want to modify
  the file descriptors, not the full PAGECACHE_FILE structure.
  If we open data file and it was closed, share->bitmap.file needs
  to be set.
  Note that the modified code is disabled anyway.
storage/maria/ma_recovery.c:
  Checkpoint record does not contain kfile/dfile descriptors anymore
  so code can be simplified. Hash key in all_dirty_pages is 
  not made from file_descriptor & pageno anymore, but
  index_or_data & table-short-id & pageno.
  If a table's create_rename_lsn is higher than record's LSN,
  we skip the table and don't fail if it's corrupted (because the LSNs
  say that we don't have to look at this table).
  If a table is skipped (for example due to create_rename_lsn),
  its UNDOs still cause undo_lsn to advance; this is so that if later
  we notice the transaction has to rollback we fail (as table should
  not be skipped in this case).
  Fixing a bug: the dirty_pages list was never used, because
  the LSN below which it was used was the minimum rec_lsn of dirty pages!
  It is now the min(checkpoint_start_log_horizon, min(trn's rec_lsn)).
  When we disable/reenable transactionality, we modify pagecache
  callbacks (needed for example for get_log_address: changing
  share->page_type is not enough anymore).
storage/maria/ma_write.c:
  'records' and 'checksum' are protected: they are updated under
  log's mutex in write-hooks when UNDO is written.
storage/maria/maria_chk.c:
  remove use of duplicate functions.
storage/maria/maria_def.h:
  set_data|index_pagecache_callbacks() need to be exported;
  _ma_reenable_logging_for_table() changes to a real function.
storage/maria/unittest/ma_pagecache_consist.c:
  new prototype
storage/maria/unittest/ma_pagecache_single.c:
  new prototype

0fbc29c197 A pre-requisite for the fix for Bug#12713 "Error in a stored function
called from a SELECT doesn't cause ROLLBACK of state"
Make private all class handler methods (PSEA API) that may modify
data. Introduce and deploy public ha_* wrappers for these methods in 
all sql/.
This necessary to keep track of all data modifications in sql/,
which is in turn necessary to be able to optimize two-phase
commit of those transactions that do not modify data.


sql/ha_partition.cc:
  Class ha_partition is no longer a friend of class handler.
  Use the public handler interface (handler::ha_ methods) for partition
  operations.

sql/handler.cc:
  Function ha_create_table() is no longer a friend of class handler.
  Use public handler::change_table_ptr() to access private members.
  This fixes a subtle bug (no test case in the test suite) when a
  deletion error occurs inside one partition of a partitioned engine. 
  The old code would crash in handler::print_error() in this case.
  
  Implement the newly introduced public ha_* wrappers of the private
  virtual handler methods.
sql/handler.h:

226700ee51 Make handler::{write,delete,update}_row private. It's critical
that the entire server uses their public ha_* counterparts instead,
since only then we can ensure proper tracing of these calls that
is necessary for Bug#12713.
A pre-requisite for Bug#12713 "Error in a stored function called from 
a SELECT doesn't cause ROLLBACK of statem"


sql/ha_partition.cc:
  Use ha_write_row, ha_update_row, ha_delete_row instead of now-private
  write_row, update_row, delete_row. 
  In future ha_* calls will contain more than just a call to the binary
  log, so it's essential they are used consistently everywhere in the server.
  
  Disable the undesired effect of double binary logging of changes
  to partitioned tables with tmp_disable_binlog.
sql/handler.h:
  Make write_row, update_row, delete_row private. It's critical
  that the entire code base uses ha_write_row, ha_update_row, ha_delete_row
  instead -- in future, ha_* counterparts will have more common
  functionality than just a call to the binary log.
sql/sql_select.cc:
  Use ha_write_row, ha_update_row, ha_delete_row instead of
  write_row, update_row, delete_row respectively. 
  The change affects the join execution code that works with an
  intermediate internal temporary table. Do not disable binary logging,
  since it's unnecessary - temporary tables are not replicated
  by row level replication.
sql/sql_table.cc:
  Use ha_write_row in copy_data_between_tables - the function
  that writes data from the original table to a temporary copy
  when executing ALTER TABLE. Do not disable binary logging
  since temporary tables are not replicated by row level 
  replication anyway.

storage/maria/ha_maria.cc:
  Use packed fields
  null_bytes are not anymore stored in a separate field
  Changes to use Maria for internal temporary tables
  Give warning if we try to do an ALTER TABLE to a unusable row format
storage/maria/ha_maria.h:
  Allow Maria with block format to restart scanning at given position
storage/maria/ma_blockrec.c:
  Added functions to remember and restore scan position
  Allocate cur_row.extents so that we don't have to do a malloc on first read
  Fixed bug when using packed row without packed strings
  Removed unneeded calls to free_full_pages()
  Fixed unlikely bug when using old bitmap to read head page and head page had gone away
  Remember row position when doing undo of delete and update row (needed for undo of key delete)

storage/maria/ma_key_recover.c:
  CLR's for UNDO_ROW_DELETE and UNDO_ROW_UPDATE now include rowid for the row.
  This was needed for undo_key_delete to work, as undo of delete row is likely to put row in a new position.
  undo_delete_key now doesn't include row position

e5a397e28f Bug#32395 Alter table under a impending global read lock causes a server crash
The problem is that some DDL statements (ALTER TABLE, CREATE
TRIGGER, FLUSH TABLES, ...) when under LOCK TABLES need to
momentarily drop the lock, reopen the table and grab the write
lock again (using reopen_tables). When grabbing the lock again,
reopen_tables doesn't pass a flag to mysql_lock_tables in
order to ignore the impending global read lock, which causes a
assertion because LOCK_open is being hold. Also dropping the
lock must not signal to any threads that the table has been
relinquished (related to the locking/flushing protocol).

The solution is to correct the way the table is reopenned
and the locks grabbed. When reopening the table and under
LOCK TABLES, the table version should be set to 0 so other
threads have to wait for the table. When grabbing the lock,
any other flush should be ignored because it's theoretically
a atomic operation. The chosen solution also fixes a potential
discrepancy between binlog and GRL (global read lock) because
table placeholders were being ignored, now a FLUSH TABLES WITH
READ LOCK will properly for table with open placeholders.

It's also important to mention that this patch doesn't fix
a potential deadlock if one uses two GRLs under LOCK TABLES
concurrently.

2a0d2fef51 Bug#12713 "Error in a stored function called from a SELECT doesn't
cause ROLLBACK of statement", part 1. Review fixes.

Do not send OK/EOF packets to the client until we reached the end of 
the current statement.
This is a consolidation, to keep the functionality that is shared by all 
SQL statements in one place in the server.
Currently this functionality includes:
- close_thread_tables()
- log_slow_statement().

After this patch and the subsequent patch for Bug#12713, it shall also include:
- ha_autocommit_or_rollback()
- net_end_statement()
- query_cache_end_of_result().

In future it may also include:
- mysql_reset_thd_for_next_command().


include/mysql_com.h:
  Rename now unused members of NET: no_send_ok, no_send_error, report_error.
  These were server-specific variables related to the client/server
  protocol. They have been made obsolete by this patch.
  
  Previously the same members of NET were used to store the error message
  both on the client and on the server. 
  The error message was stored in net.last_error (client: mysql->net.last_error,
  server: thd->net.last_error).
  The error code was stored in net.last_errno (client: mysql->net.last_errno,
  server: thd->net.last_errno).
  The server error code and message are now stored elsewhere 
  (in the Diagnostics_area), thus NET members are no longer used by the
  server.
  Rename last_error to client_last_error, last_errno to client_last_errno
  to avoid potential bugs introduced by merges.
include/mysql_h.ic:
  Update the ABI file to reflect a rename. 
  Renames do not break the binary compatibility.
libmysql/libmysql.c:
  Rename last_error to client_last_error, last_errno to client_last_errno.
  This is necessary to ensure no unnoticed bugs introduced by merged
  changesets.
  
  Remove net.report_error, net.no_send_ok, net.no_send_error.
libmysql/manager.c:
  Rename net.last_errno to net.client_last_errno.
libmysqld/lib_sql.cc:
  Rename net.last_errno to net.client_last_errno.
  
  Update the embedded implementation of the client-server protocol to
  reflect the refactoring of protocol.cc.
libmysqld/libmysqld.c:
  Rename net.last_errno to net.client_last_errno.
mysql-test/r/events.result:
  Update to reflect the change in mysql_rm_db(). Now we drop stored
  routines and events for a given database name only if there
  is a directory for this database name. ha_drop_database() and
  query_cache_invalidate() are called likewise. 
  Previously we would attempt to drop routines/events even if database
  directory was not found (it worked, since routines and events are stored
  in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
  does not exist".
  The change was done because the previous code used to call send_ok()
  twice, which led to an assertion failure when asserts against it were
  added by this patch.
mysql-test/r/grant.result:
  Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error 
  if mysql.procs_priv is missing.
  This fixes the assert that send_ok() must not called after send_error()
  (the original patch for Bug 16470 was prone to this).
mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
  Produce a more detailed error message.
mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:
  Produce a more detailed error message.
mysql-test/t/grant.test:
  Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv
  is missing.
server-tools/instance-manager/mysql_connection.cc:
  Rename net.last_errno to net.client_last_errno.
sql/ha_ndbcluster_binlog.cc:
  Add asserts. 
  
  Use getters to access statement status information.
  
  Add a comment why run_query() is broken. Reset the diagnostics area
  in the end of run_query() to fulfill the invariant that the diagnostics_area
  is never assigned twice per statement (see the comment in the code
  when this can happen). We still do not clear thd->is_fatal_error and
  thd->is_slave_error, which may lead to bugs, I consider the whole affair
  as something to be dealt with separately.
sql/ha_partition.cc:
  fatal_error() doesn't set an error by itself. Perhaps we should
  remove this method altogether and instead add a flag to my_error 
  to set thd->is_fatal_error property.
  
  Meanwhile, this change is a part of inspection made to the entire source
  code with the goal to ensure that fatal_error()
  is always accompanied by my_error().
sql/item_func.cc:
  There is no net.last_error anymore. Remove the obsolete assignment.
sql/log_event.cc:
  Use getters to access statement error status information.
sql/log_event_old.cc:
  Use getters to access statement error status information.
sql/mysqld.cc:
  Previously, if a continue handler for an error was found, my_message_sql() 
  would not set an error in THD. Since the current statement
  must be aborted in any case, find_handler() had a hack to assign 
  thd->net.report_error to 1.
  
  Remove this hack. Set an error in my_message_sql() even if the continue
  handler is found. The error will be cleared anyway when the handler
  is executed. This is one action among many in this patch to ensure the 
  invariant that whenever thd->is_error() is TRUE, we have a message in 
  thd->main_da.message().
sql/net_serv.cc:
  Use a full-blown my_error() in net_serv.cc to report an error,
  instead of just setting net->last_errno. This ensures the invariant that
  whenever thd->is_error() returns TRUE, we have a message in 
  thd->main_da.message().
  
  Remove initialization of removed NET members.
sql/opt_range.cc:
  Use my_error() instead of just raising thd->net.report_error. 
  This ensures the invariant that whenever thd->is_error() returns TRUE, 
  there is a message in thd->main_da.message().
sql/opt_sum.cc:
  Move invocation of fatal_error() right next to the place where
  we set the error message. That makes it easier to track that whenever
  fatal_error() is called, there is a message in THD.
sql/protocol.cc:
  Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() 
  respectively. These functions write directly to the network and are not 
  for use anywhere outside the client/server protocol code. 
  
  Remove the code that was responsible for cases when either there is 
  no error code, or no error message, or both.
  Instead the calling code ensures that they are always present. Asserts
  are added to enforce the invariant.
  
  Instead of a direct access to thd->server_status and thd->total_warn_count
  use function parameters, since these from now on don't always come directly
  from THD.
  
  Introduce net_end_statement(), the single-entry-point replacement API for 
  send_ok(), send_eof() and net_send_error().
  
  Implement Protocol::end_partial_result_set to use in select_send::abort()
  when there is a continue handler.
sql/protocol.h:
  Update declarations.
sql/repl_failsafe.cc:
  Use getters to access statement status information in THD.
  Rename net.last_error to net.client_last_error.
sql/rpl_record.cc:
  Set an error message in prepare_record() if there is no default
  value for the field -- later we do print this message to the client.
sql/rpl_rli.cc:
  Use getters to access statement status information in THD.
sql/slave.cc:
  In create_table_from_dump() (a common function that is used in 
  LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
  with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
  
  Update has_temporary_error() to work correctly when no error is set.
  This is the case when Incident_log_event is executed: it always returns
  an error but does not set an error message.
  
  Use getters to access error status information.
sql/sp_head.cc:
  Instead of hacks with no_send_error, work through the diagnostics area 
  interface to suppress sending of OK/ERROR packets to the client.
  
  Move query_cache_end_of_result before log_slow_statement(), similarly
  to how it's done in dispatch_command().
sql/sp_rcontext.cc:
  Remove hacks with assignment of thd->net.report_error, they are not
  necessary any more (see the changes in mysqld.cc).
sql/sql_acl.cc:
  Use getters to access error status information in THD.
sql/sql_base.cc:
  Access thd->main_da.sql_errno() only if there is an error. This fixes
  a bug when auto-discovery, that was effectively disabled under pre-locking.
sql/sql_binlog.cc:
  Remove hacks with no_send_ok/no_send_error, they are not necessary 
  anymore: the caller is responsible for network communication.
sql/sql_cache.cc:
  Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
  if the response has been served from the query cache. This raises the 
  question whether we should store EOF packet in the query cache at all,
  or generate it anew for each statement (we should generate it anew), but
  this is to be addressed separately.
sql/sql_class.cc:
  Implement class Diagnostics_area. Please see comments in sql_class.h
  for details.
  
  Fix a subtle coding mistake in select_send::send_data: when on slave, 
  an error in Item::send() was ignored.
  The problem became visible due to asserts that the diagnostics area is
  never double assigned.
  
  Remove initialization of removed NET members.
  
  In select_send::abort() do not call select_send::send_eof(). This is
  not inheritance-safe. Even if a stored procedure continue handler is
  found, the current statement is aborted, not succeeded.
  Instead introduce a Protocol API to send the required response, 
  Protocol::end_partial_result_set().
  
  This simplifies implementation of select_send::send_eof(). No need
  to add more asserts that there is no error, there is an assert inside
  Diagnostics_area::set_ok_status() already.
  
  Leave no trace of no_send_* in the code.
sql/sql_class.h:
  Declare class Diagnostics_area. 
  
  Remove the hack with no_send_ok from
  Substatement_state.
  
  Provide inline implementations of send_ok/send_eof.
  
  Add commetns.
sql/sql_connect.cc:
  Remove hacks with no_send_error. 
  
  Since now an error in THD is always set if net->error, it's not necessary
  to check both net->error and thd->is_error() in the do_command loop.
  
  Use thd->main_da.message() instead of net->last_errno.
  
  Remove the hack with is_slave_error in sys_init_connect. Since now we do not
  reset the diagnostics area in net_send_error (it's reset at the beginning
  of the next statement), we can access it safely even after 
  execute_init_command.
sql/sql_db.cc:
  Update the code to satisfy the invariant that the diagnostics area is never
  assigned twice.
  Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if 
  mysql.proc does not exist".
sql/sql_delete.cc:
  Change multi-delete to abort in abort(), as per select_send protocol.
  Fixes the merge error with the test for Bug 29136
sql/sql_derived.cc:
  Use getters to access error information.
sql/sql_insert.cc:
  Use getters to access error information.
sql-common/client.c:
  Rename last_error to client_last_error, last_errno to client_last_errno.
sql/sql_parse.cc:
  Remove hacks with no_send_error. Deploy net_end_statement().
  
  The story of COM_SHUTDOWN is interesting. Long story short, the server 
  would become on its death's door, and only no_send_ok/no_send_error assigned
  by send_ok()/net_send_error() would hide its babbling from the client.
  
  First of all, COM_QUIT does not require a response. So, the comment saying
  "Let's send a response to possible COM_QUIT" is not only groundless 
  (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after 
  COM_SHUTDOWN), it's plainly incorrect.
  
  Secondly, besides this additional 'OK' packet to respond to a hypothetical
  COM_QUIT, there was the following code in dispatch_command():
  
  if (thd->killed)
    thd->send_kill_message();
  if (thd->is_error()
    net_send_error(thd);
  
  This worked out really funny for the thread through which COM_SHUTDOWN
  was delivered: we would get COM_SHUTDOWN, say okay, say okay again, 
  kill everybody, get the kill signal ourselves, and then attempt to say 
  "Server shutdown in progress" to the client that is very likely long gone.
  
  This all became visible when asserts were added that the Diagnostics_area
  is not assigned twice.
  
  Move query_cache_end_of_result() to the end of dispatch_command(), since
  net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
  is a no-op if there is no started query in the cache.
  
  Consistently use select_send interface to call abort() or send_eof()
  depending on the operation result.
  
  Remove thd->fatal_error() from reset_master(), it was a no-op. 
  in hacks with no_send_error woudl save us
  from complete breakage of the client/server protocol.
  
  Consistently use select_send::abort() whenever there is an error, 
  and select_send::send_eof() in case of success.
  The issue became visible due to added asserts.
sql/sql_partition.cc:
  Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:
  Deploy class Diagnostics_area.
  Remove the unnecessary juggling with the protocol in 
  Select_fetch_protocol_binary::send_eof(). EOF packet format is 
  protocol-independent.
sql/sql_select.cc:
  Call fatal_error() directly in opt_sum_query.
  Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
  Use getters to access error information in THD.
sql/sql_show.cc:
  Use getters to access error information in THD.
  
  Add comments.
  
  Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
  Replace hacks with no_send_ok with the interface of the diagnostics area.
  
  Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
  Introduce multi_update::abort(), which is the proper way to abort a
  multi-update. This fixes the merge conflict between this patch and
  the patch for Bug 29136.
sql/table.cc:
  Use a getter to access error information in THD.
sql/tztime.cc:
  Use a getter to access error information in THD.

87143063d3 Bug#23713 LOCK TABLES + CREATE TRIGGER + FLUSH TABLES WITH READ LOCK = deadlock
This bug is actually two bugs in one, one of which is CREATE TRIGGER under
LOCK TABLES and the other is CREATE TRIGGER under LOCK TABLES simultaneous
to a FLUSH TABLES WITH READ LOCK (global read lock). Both situations could
lead to a server crash or deadlock.

The first problem arises from the fact that when under LOCK TABLES, if the
table is in the set of locked tables, the table is already open and it doesn't
need to be reopened (not a placeholder). Also in this case, if the table is
not write locked, a exclusive lock can't be acquired because of a possible
deadlock with another thread also holding a (read) lock on the table. The
second issue arises from the fact that one should never wait for a global
read lock if it's holding any locked tables, because the global read lock
is waiting for these tables and this leads to a circular wait deadlock.

The solution for the first case is to check if the table is write locked
and upgraded the write lock to a exclusive lock and fail otherwise for non
write locked tables. Grabbin the exclusive lock in this case also means
to ensure that the table is opened only by the calling thread. The second
issue is partly fixed by not waiting for the global read lock if the thread
is holding any locked tables.

The second issue is only partly addressed in this patch because it turned
out to be much wider and also affects other DDL statements. Reported as

4b00263596 Bug#31479 Bad lock interaction if CREATE TABLE LIKE is killed
Kill of a CREATE TABLE source_table LIKE statement waiting for a
name-lock on the source table causes a bad lock interaction.

The mysql_create_like_table() has a bug that if the connection is
killed while waiting for the name-lock on the source table, it will
jump to the wrong error path and try to unlock the source table and
LOCK_open, but both weren't locked.

The solution is to simple return when the name lock request is killed,
it's safe to do so because no lock was acquired and no cleanup is needed.

Original bug report also contains description of other problems
related to this scenario but they either already fixed in 5.1 or
will be addressed separately (see bug report for details).

6b3fed49ea Bug#32178 server crash when select from i_s and concurrent partition management
The crash happens because we change share->partition_info where 'share' is global struct
(it affects other threads which use the same 'share').
It causes discrepancy between 'share' and handler data. 
The fix:
Move share->partition_info update into WFRM_INSTALL_SHADOW part which is protected by OPEN_lock.


sql/sql_partition.cc:
  fast_end_partition: added close_thread_tables() for the case when error occures

4d6543a6f0 Bug#31397 Inconsistent drop table behavior of handler tables.
The problem is that DROP TABLE and other DDL statements failed to
automatically close handlers associated with tables that were marked
for reopen (FLUSH TABLES).

The current implementation fails to properly discard handlers of
dropped tables (that were marked for reopen) because it searches
on the open handler tables list and using the current alias of the
table being dropped. The problem is that it must not use the open
handler tables list to search because the table might have been
closed (marked for reopen) by a flush tables command and also it
must not use the current table alias at all since multiple different
aliases may be associated with a single table. This is specially
visible when a user has two open handlers (using alias) of a same
table and a flush tables command is issued before the table is
dropped (see test case). Scanning the handler table list is also
useless for dropping handlers associated with temporary tables,
because temporary tables are not kept in the THD::handler_tables
list.

The solution is to simple scan the handlers hash table searching
for, and deleting all handlers with matching table names if the
reopen flag is not passed to the flush function, indicating that
the handlers should be deleted. All matching handlers are deleted
even if the associated the table is not open.

  The hash_free function is moved to the cleanup.
sql/sql_handler.cc:
  When dropping tables for a final close, scan the handler's hash table since
  the table might not be in the handlers open table list because the table was
  marked for reopen or because it's a temporary table.
sql/sql_rename.cc:
  Drop handlers associated with tables that are being renamed.
sql/sql_table.cc:
  Now that temporary tables are properly removed even when opened
  by a SQL HANDLER, enable the assert since this branch can't be taken
  outside of SF/trigger/prelocked mode.
