Just "Master" could be understood as the master IP or hostname and thus can
cause confusion to db admins. "Master connection name" clearly states that
the log line contains connection name in the (possibly) multi-master setup.

it was never doing anything anyway

make_cond_for_info_schema() does preserve outer fields

MDEV-8685 MariaDB fails to decode Anonymous_GTID entries
MDEV-5705 Replication testing: 5.6->10.0

- Ignoring GTID events from MySQL 5.6+ (Allows replication from MySQL 5.6+ with GTID enabled)
- Added ignorable events from MySQL 5.6
- mysqlbinlog now writes information about GTID and ignorable events.
- Added more information in error message when replication stops because of wrong information in binary log.
- Fixed wrong test when write_on_release() should flush cache.

(even when configured with --binlog-format=statement).
Before we got an error on the slave and the slave stopped if the master
was configured with --binlog-format=mixed or --binlog-format=row.

When we calculate max_key_len for RANGE_OPT_PARAM::min_key/max_key, take
into account that QUICK_RANGE::QUICK_RANGE for some reason assumes
that there is one more byte there:

      max_key((uchar*) sql_memdup(max_key_arg,max_length_arg+1)),

EXPLAIN INSERT ... SELECT tried to use SELECT's execution path. This
caused a collection of problems:
- SELECT_DESCRIBE flag was not put into select_lex->options, which
  means it was not in JOIN::select_options either (except for the first
  member of the UNION).
- This caused UNION members to be executed. They would attempt to write
  join output rows to the output.
- (Actual cause of the crash) second join sibling would call
  result->send_eof() when finished execution. Then,
  Explain_query::print_explain would attempt to write to query output
  again, and cause an assertion due to non-empty query output.

Substitute into transformed subselects original left expression and than register its change in case it was substituted.

MDEV-7565: Server crash with Signal 6 (part 2)

followup test suite and its fix.

Problem was in rewriting left expression which had 2 references on it. Solved with making subselect reference main.

Item_in_optimized can have not Item_in_subselect reference in left part so type casting with no check is dangerous.

Item::cols() should be checked after Item::fix_fields().

Preparation of subselect moved earlier (before checks which needs it prepared).

[EXPLAIN] INSERT .. SELECT creates a select_insert object.
select_insert calls handler->start_bulk_insert() during
initialization.

For MyISAM/Aria this requires that a matching call to
handler->end_bulk_insert() call is made.

Regular INSERT .. SELECT accomplishes this by calling either
select_result->send_eof() or select_result->abort_result_set().

EXPLAIN INSERT ... SELECT didn't call either, which resulted in
improper de-initializaiton of handler object. Make it call
abort_result_set(), which invokes handler->end_bulk_insert().

Corrected variable name in dead code for consistency.

Patch contributed by Michal Hrusecky.

Fixed unclean prototype declaration. According to ISO/IEC 9899:TC2:
...
10. The special case of an unnamed parameter of type void as the only item in
    the list specifies that the function has no parameters.
...
14. An identifier list declares only the identifiers of the parameters of the
    function. An empty list in a function declarator that is part of a
    definition of that function specifies that the function has no parameters.
    The empty list in a function declarator that is not part of a definition of
    that function specifies that no information about the number or types of the
    parameters is supplied. 124)

6.11.6 Function declarators

The use of function declarators with empty parentheses (not prototype-format
parameter type declarators) is an obsolescent feature.

MDEV-8845: Table disappear after modifying FK

Added test case.

Fixed incorrect access to freed memory.

Made no_rows_in_result()/restore_to_before_no_rows_in_result() not looking
annecessary deep with walk() method.

The patch was pushed into 10.0, but it needs to be applied to 5.5 as well

The test restarts the server and expects that the feedback plugin
will send a report on shutdown, and will write about it in the error
log. But the server is only given 10 sec to shut down properly,
which is not always enough.
Added a parameter to restart_mysqld.inc, and set it to a bigger
value in feedback_plugin_send
