message:
Bug#28870 check that table locks are released/reset
    
The problem is that some mysql_lock_tables error paths are not
resetting the tables lock type back to TL_UNLOCK. If the lock
types are not reset properly, a table might be returned to the
table cache with wrong lock_type.
      
The proposed fix is to ensure that the tables lock type is always
properly reset when mysql_lock_tables fails. This is a
incompatible change with respect to the process state information.


sql/lock.cc:
  Merge mysql_lock_tables cleanup sequence and the reset_lock_data
  function into a single function and take steps to ensure it is
  always called for each error exit path. Also remove references
  to the redundant THD::locked variable which was almost exclusively
  used by this function and the same information is already on proc_info.
sql/sql_class.cc:
  Remove references to the THD::locked variable.
sql/sql_class.h:
  Remove the THD::locked variable.
sql/sql_show.cc:
  Remove references to THD:locked, state_info will now default to proc_info.

a962160eec Merge with MySQL 5.1, with following additions:
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.

This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.

70c7e936db Backport of Bug#33204 from mysql-pe to
mysql-next-mr-bugfixing.

Bug no 32858 was fixed in two different ways in what was
then called mysql 5.1 and 6.0. The fix in 6.0 was very
different since bugfix no 33204 was present.  Furthermore,
the two fixes were not compatible. Hence in order to
backport Bug#33204 to the 5.1-based mysql-next-mr-bugfixing,
it was necessary to remove the 5.1 fix of 32858 and apply
the 6.0 version of the fix.

19c380aaff WL#2687 WL#5072 BUG#40278 BUG#47175
Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.

In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.

This caused crash(es). 

Fixed by adding error handling code to both the WHERE

f130de4fb8 A patch and a test case for
Bug#46539 Various crashes on INSERT IGNORE SELECT + SELECT FOR UPDATE.

If a transaction was rolled back inside InnoDB due to a deadlock
or lock wait timeout, and the statement had IGNORE clause,
the server could crash at the end of the statement or on shutdown.

This was caused by the error handling infrastructure's attempt to 
ignore a non-ignorable error.

When a transaction rollback request is raised, switch off 
current_select->no_error flag, so that the following error
won't be ignored.

Instead, we could add !thd->is_fatal_sub_stmt_error to
my_message_sql(), but since in write_record() we switch
off no_error, the same approach is used in 
thd_mark_transaction_to_rollback().

@todo: call thd_mark_transaction_to_rollback() from 
handler::print_error(), then we can easily make sure
that the error reported by print_error is not ignored.

message:
  Fix for Bug#43138: DROP DATABASE failure does not clean up message list.
  
  The problem was that the high-level function mysql_rm_db() invoked
  low-level mysql_rm_table_part2(), which reported low-level error
  (Unknown table) if SE refused to delete a table. Also when
  mysql_rm_table_part2() reported an error, it didn't add corresponding
  warning into the list (because it is used from other places where such
  behaviour is required).
  
  The fix is to
    1. Remove no_warnings_for_error usage from sql_table.cc
    2. Improve internal error handler support in THD, so that
       a stack of error handlers is allowed.
    3. Create an internal error handler (Drop_table_error_handler)
       to silence useless warnings.
    4. Use the handler in DROP DATABASE and DROP TABLE statements.

  Follow-up for fix for bug "Bug#43138: DROP DATABASE failure
  does not clean up message list".
  
  Fixed drop.test failure under non-debug server by moving part
  of test dependent on debug-only feature to separate .test file,
  which won't be run for non-debug versions of server.

8ec23470f1 Backport of revno 2630.28.10, 2630.28.31, 2630.28.26, 2630.33.1,
2630.39.1, 2630.28.29, 2630.34.3, 2630.34.2, 2630.34.1, 2630.29.29,
2630.29.28, 2630.31.1, 2630.28.13, 2630.28.10, 2617.23.14 and
some other minor revisions.

This patch implements: 

WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).

WL#4435: Support OUT-parameters in prepared statements.

(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).

Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.

After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.

When using the binary protocol, send the parameters in an additional result
set over the wire.  When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.

The following refactoring has been made:
  - Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
  - A new Protocol::send_result_set_row() was introduced to incapsulate
    common functionality for sending row data.
  - Signature of Protocol::prepare_for_send() was changed: this operation
    does not need a list of items, the number of items is fully sufficient.

The following backward incompatible changes have been made:
  - CLIENT_MULTI_RESULTS is now enabled by default in the client;
  - CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.

include/mysql.h:
  Add a new flag to MYSQL_METHODS::flush_use_result
  function pointer. This flag determines if all results
  should be flushed or only the first one:
      
  - if flush_all_results is TRUE, then cli_flush_use_result()
    will read/flush all pending results. I.e. it will read
    all packets while server status attribute indicates that
    there are more results. This is a new semantic, required
    to fix the bug.
              
  - if flush_all_results is FALSE, the old sematic
    is preserved -- i.e. cli_flush_use_result() reads data
    until first EOF-packet.
include/mysql.h.pp:
  Update the ABI with new calls (compatible changes).
include/mysql_com.h:
  Add CLIENT_PS_OUT_PARAMS -- a client capability indicating that the client supportsю
libmysql/libmysql.c:
  Add mysql_stmt_next_result() -- analogue of mysql_next_result() for binary protocol.
  Fix a minor bug in alloc_fields() -- not all members were copied over,
  and some only shallow-copied (catalog).
  Flush all results in mysql_stmt_close() (Bug#39519).
libmysqld/lib_sql.cc:
  Rename send_fields() -> send_result_set_metadata().
  Refactoring: change prepare_for_send() so that it accepts only 
  what it really needs -- a number of elements in the list.
mysql-test/r/ps.result:
  Update results: WL#4435.
mysql-test/t/ps.test:
  WL#4435: A test case for an SQL-part of the problem.
sql-common/client.c:
  Bug#39519.
  Implement new functionality in cli_flush_use_result():
  if flush_all_delete is TRUE, then it should read/flush
  all pending results.
sql/Makefile.am:
  Add a new header sql_prepare.h to the list
  of build headers.
sql/events.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/handler.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/mysql_priv.h:
  Move sql_prepare.cc-specific declarations to a new
  header - sql_prepare.h.
sql/procedure.h:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/protocol.cc:
  Move the logic responsible for sending of one result
  set row to the Protocol class. Define a template
  for end-of-statement action. 
  Refactoring: change prepare_for_send() so that it accepts 
  only what it really needs -- a number of elements in the list.
  Rename send_fields() to send_result_set_metadata().
sql/protocol.h:
  Update with new declarations (WL#4435).
  Rename send_fields() -> send_result_set_metadata().
  prepare_for_send() only needs the number of columns to send,
  and doesn't use the item list - update signature to require
  only what's needed.
  Add a new protocol type -- Protocol_local.
sql/repl_failsafe.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/slave.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_acl.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_base.cc:
  Include sql_prepare.h (for Reprepare_observer).
sql/sql_cache.cc:
  Extend the query cache flags block to be able
  to store a numeric id for the result format,
  not just a flag binary/non-binary.
sql/sql_class.cc:
  Update to use the rename of Protocol::send_fields()
  to Protocol::send_result_set_metadata().
  Use Protocol::send_one_result_set_row().
sql/sql_class.h:
  Move the declaration of Reprepare_observer to the 
  new header - sql_prepare.h.
  Update to the new signature of class Protocol::send_fields().
sql/sql_connect.cc:
  Use a protocol template method instead of
  raw NET layer API at the end of a statement.
sql/sql_cursor.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_error.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_handler.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
  Use new method Protocol::send_one_result_set_row().
sql/sql_help.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_lex.cc:
  Initialize multi_statements variable.
  Add a handy constant for empty lex
  string.
sql/sql_lex.h:
  Add a separate member for a standalone
  parsing option - multi-statements support.
sql/sql_list.cc:
  sql_list.h is a standalone header now, 
  no need to include mysql_priv.h.
sql/sql_list.h:
  Make sql_list.h a stand-alone header.
sql/sql_parse.cc:
  Include sql_prepare.h for prepared
  statements- related declarations.
  Use a new Protocol template method to end
  each statement (send OK, EOF or ERROR to
  the client).
sql/sql_prepare.cc:
  Implement Execute Direct API (WL#4264), 
  currently unused. It will be used by the service
  interface (Backup).
  Use a new header - sql_prepare.h.
  Add support for OUT parameters in the 
  binary and text protocol (prepared statements 
  only).
sql/sql_prepare.h:
  Add a new header to contain (for now)
  all prepared statement- external
  related declarations.
sql/sql_profile.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_repl.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_select.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_show.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_string.h:
  Add a way to convert a String to LEX_STRING.
sql/sql_table.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_update.cc:
  Remove an extraneous my_error(). The error
  is already reported in update_non_unique_table_error().
sql/sql_yacc.yy:
  Support for multi-statements is an independent
  property of parsing, not derived from 
  the protocol type.
tests/mysql_client_test.c:
  Add tests for WL#4435 (binary protocol).
