SQLCOM_ASSIGN_TO_KEYCACHE should not be CF_AUTO_COMMIT_TRANS
  SQLCOM_PRELOAD_KEYS should not be CF_AUTO_COMMIT_TRANS
  SQLCOM_INSTALL_PLUGIN should need CF_AUTO_COMMIT_TRANS
  SQLCOM_UNINSTALL_PLUGIN should need CF_AUTO_COMMIT_TRANS

75908fc4ce BUG#13627921 - MISSING FLAGS IN SQL_COMMAND_FLAGS MAY LEAD TO REPLICATION PROBLEMS
merge from MySQL-5.6, revision:

revno: 3677.2.1
committer: Alfranio Correia <alfranio.correia@oracle.com>

message:
  BUG#13627921 - MISSING FLAGS IN SQL_COMMAND_FLAGS MAY LEAD TO REPLICATION PROBLEMS

  Flags in sql_command_flags[command] are not correctly set for the following
  commands:

    . SQLCOM_SET_OPTION is missing CF_CAN_GENERATE_ROW_EVENTS;
    . SQLCOM_BINLOG_BASE64_EVENT is missing CF_CAN_GENERATE_ROW_EVENTS;
    . SQLCOM_REVOKE_ALL is missing CF_CHANGES_DATA;
    . SQLCOM_CREATE_FUNCTION is missing CF_AUTO_COMMIT_TRANS;

  This may lead to a wrong sequence of events in the binary log. To fix
  the problem, we correctly set the flags in sql_command_flags[command].

70823e1d91 MDEV-5120 Test suite test maria-no-logging fails
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.

This patch fixes so that we always include my_global.h or my_config.h before we include any other files.

Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
  "always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

sql/item.cc:

sql/sql_acl.cc:
  when updating the hostname of the ACL_USER, update the hostname_length too
sql/sql_parse.cc:
  first compare the username string, then test the host pointer
  (host pointer is undefined when the username string is one of the hard-coded values
  set by the parser). This is not a bug, old code is perfectly safe as the undefined
  host pointer is never dereferenced, but let's keep valgrind happy.

8e4566e912 Don't give warning if there are two unique keys used with INSERT .. ON DUPLICATE KEY UPDATE.
We should assume that the store engine will report the first duplicate key for this case.

Old code of suppression of unsafe logging error with LIMIT didn't work, because of wrong usage of my_interval_timer().

Suppress unsafe logging errors to the error log if we get too many unsafe logging errors in a short time.
This is to not overflow the error log with meaningless errors.

- Each error code is suppressed and counted separately.
- We do a 5 minute suppression of new errors if we get more than 10 errors in that time.

Only print unsafe logging errors if log_warnings > 1.

  More DBUG
sql/sql_class.cc:
  Changed that thd_sqlcom_can_generate_row_events() does not report that CREATE OR REPLACE is generating row events.
  This is safe as this function is only used by InnoDB/XtraDB to check if a query is generating row events as part of another transaction. As CREATE is always run as it's own transaction, this isn't a problem.
  This fixed MDEV-6525.
sql/sql_table.cc:
  Remember if reopen_tables() generates an error (which can only happen in case of KILL).
  This fixed MDEV-6560

6b720ae4cb MDEV-6605 Multiple Clients Inserting Causing Error: Failed to read auto-increment value from storage engine
* handler::get_auto_increment() was not expecting any errors from the storage engine.
  That was wrong, errors could happen.
* ha_partition::get_auto_increment() was doing index lookups in partition under a mutex.
  This was redundant (engine transaction isolation was covering that anyway)
  and harmful (causing deadlocks).

0c148e413f MDEV-6610 Assertion `thd->is_error() || thd->killed' failed in mysql_execute_command on executing an SP with repeated CREATE TABLE .. SELECT
the bug was introduced by CREATE OR REPLACE implementation.
CREATE IF NOT EXISTS ... SELECT was returning an error status to the caller,
while sending an ok packet to the user. SP code was not prepared for that
and trusted that error status means an error.

9392d0e280 - MDEV-6695 Bad column name for UCS2 string literals
The Item_string constructors called set_name() on the source string,
  which was wrong because in case of UCS2/UTF16/UTF32 the source value
  might be a not well formed string (e.g. have incomplete leftmost character).
  Now set_name() is called on str_value after its copied 
  (with optionally left zero padding) from the source string.
- MDEV-6694 Illegal mix of collation with a PS parameter
  Item_param::convert_str_value() did not set repertoire.
  Introducing a new structure MY_STRING_METADATA to collect
  character length and repertoire of a string in a single loop,
  to avoid two separate loops. Adding a new class Item_basic_value::Metadata
  as a convenience wrapper around MY_STRING_METADATA, to reuse the
  code between Item_string and Item_param.

bf4347eba0 Creating a new class in_string::Item_string_for_in_vector
and moving set_value() from Item_string to Item_string_for_in_vector,
as set_value() updates the members incompletely
(e.g. does not update max_length),
so it was dangerous to have set_value() available in Item_string.

36f50be970 MDEV-6462: Slave replicating using GTID doesn't recover correctly when master crashes in the middle of transaction
If the slave gets a reconnect in the middle of a GTID event group, normally
it will re-fetch that event group, skipping the first part that was already
queued for the SQL thread.

However, if the master crashed while writing the event group, the group is
incomplete. This patch detects this case and makes sure that the
transaction is rolled back and nothing is skipped from any following
event groups.

Similarly, a network proxy might cause the reconnect to end up on a
different master server. Detect this by noticing a different server_id,
and similarly in this case roll back the partially received group.
