  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.

  Remember if reopen_tables() generates an error (which can only happen in case of KILL).

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.

master_info_index becomes zero during shutdown.
check that it's valid (under a mutex) before dereferencing.

  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.

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.

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.

MDEV-6683 A parameter and a string literal with the same values are not recognized as equal by the optimizer

Item_string::eq() and Item_param::eq() in string context behaved differently.
Introducing a new class Item_basic_value to share the eq() code between
literals (Item_int, Item_double, Item_string, Item_null) and Item_param.

Made test smaller.

MDEV-6666 Malformed result for CONCAT(utf8_column, binary_string)

Item_static_string_func::safe_charset_converter() and 
Item_hex_string::safe_charset_converter() did not
handle character sets with mbminlen>1 properly, as well as
did not handle conversion from binary to multi-byte well.

Introducing Item::const_charset_converter(), to reuse it in a number
of Item_*::safe_charset_converter().

Analysis: When database is migrated from 5.5 or earlier and
database needs crash recovery, there is possibility that
SYS_DATAFILES system table does not exists, but
crash recovery in function dict_check_tablespaces_and_store_max_id()
assumes that SYS_DATAFILES exists.

Fix: If SYS_DATAFILES does not exists, create it before
we end up to function dict_check_tablespaces_and_store_max_id()
on crash recovery.

Adding collation usage statistics into the feedback plugin I_S table.

mysql-test/mysql-test-run.pl:
  fix the message

After-review fixes.

Mainly catching if the wait in wait_for_workers_idle() is aborted due to kill.
In this case, we should return an error and not proceed to execute the format
description event, as other threads might still be running for a bit until the
error is caught in all threads.

Follow-up patch, fixing a possible deadlock issue.

If the master crashes in the middle of an event group, there can be an active
transaction in a worker thread when we encounter the following master restart
format description event. In this case, we need to notify that worker thread
to abort and roll back the partial event group. Otherwise a deadlock occurs:
the worker thread waits for the commit that never arrives, and the SQL driver
thread waits for the worker thread to complete its event group, which it never
does.

When a view is merged, mark its select_lex as already optimized, otherwise
its where clause (which doesn't have to be a valid Item after merging)
might be accessed later. But don't do that for inserts (where a view cannot
be simply merged, if one later needs to insert into it).

The version previous to this one is a preliminary test version and

- Handle indexed UPDATE/DELETE. Previously this was just tested and
  an error message send when it could not be done. Now CONNECT can
  do it in all the cases. It is done by a MRR like tchnique by making
  a list of all update or delete to do, sort them, then execute them.

A new command line option "galera-sst-mode" was introduced
in mysqldump as part of fix for MDEV-6316. But, since the
fix was pushed to maria-10.0-galera branch, the mysqldump
tool supplied with mariadb client deb/rpm packages, does not
have this new opion.
This fix contains the same patch along with a test case.
