The test is for a bug that was introduced in MySQL 5.7.18
but not MariaDB 10.2, because MariaDB did not merge the change
that was considered incomplete and too risky for a GA release:

Bug#23481444 OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE INDEX
APPLIED BY UNCOMMITTED ROWS

So, we are only merging the test changes from the bug fix in MySQL 5.7.19,
not any code changes:

    Bug #25793677   INNODB: FAILING ASSERTION: CLUST_TEMPL_FOR_SEC || LEN

MariaDB 10.2 never contained the Oracle change

Bug#23481444 OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE
INDEX APPLIED BY UNCOMMITTED ROWS

because it was considered risky for a GA release and incomplete.
Remove the references that were added when merging MySQL 5.6.36
to MariaDB 10.0.31, 10.1.24, and 10.2.7.

Analysis:
========

(1) During TRUNCATE of file_per_table tablespace, dict_operation_lock is
released before eviction of dirty pages of a tablespace from the buffer
pool. After eviction, we try to re-acquire
dict_operation_lock (higher level latch) but we already hold lower
level latch (index->lock). This causes latch order violation

(2) Deadlock issue is present if child table is being truncated and it
holds index lock. At the same time, cascade dml happens and it took
dict_operation_lock and waiting for index lock.

Fix:
====
1) Release the indexes lock before releasing the dict operation lock.

2) Ignore the cascading dml operation on the parent table, for the
cascading foreign key, if the child table is truncated or if it is
in the process of being truncated.

Issue
====
The issue is that the info message that InnoDB prints when a table
is created with a reference which doesn't exist fills up the log as
it's printed for every insert when foreign_key_checks is disabled.

Fix
===
The fix is to display the message only if foreign_key_checks is
enabled.

Problem:
=======
   Offsets allocates memory from row_heap even for deleted row
traversal during table rebuild.

Solution:
=========
  Empty the row_heap even for deleted record. So that
offsets don't allocate memory everytime.

    Bug #25189192   ERRORS WHEN RESTARTING MYSQL AFTER RENAME TABLE.

    PROBLEM

    While renaming table innodb doesn't update the InnoDB Dictionary table
    INNODB_SYS_DATAFILES incase there is change in database while doing
    rename table. Hence on a restart the server log shows error that it
    couldnt find table with old path before rename which has actually been
    renamed. So the errors would only vanish if we update the system
    tablespace

    FIX

    Update the innodb dictionary table with new path in the case there is
    not a change in the table but the database holding the table as well.

take into account new capabilty flag which has influence on result format.

This happens because on line 59 of /usr/bin/wsrep_sst_mysqldump
we have a check :
   "if ! $MYSQL_CLIENT --version | grep 'Distrib 10.1' >/dev/null"
but the client is 10.2 so it doesnt match the grep expression.

Fixed check to be:
      "if ! $MYSQL_CLIENT --version | grep 'Distrib 10.' >/dev/null"
so that every 10. version is accepted.

Disable change buffering, so that some data that was previously
written to the encrypted redo log will not end up being copied
to the unencrypted redo log due to change buffer merge.

The thd_destructor_proxy detects that no transactions are active and
starts srv_shutdown_bg_undo_sources(), but fails to take into account
that new transactions can still start, especially be slave but also
by other threads. In addition there is no mutex when checking for
active transaction so this is not safe.

We relax the failing InnoDB debug assertion by allowing the execution
of user transactions after the purge thread has been shut down.

FIXME: If innodb_fast_shutdown=0, we should somehow guarantee that no
new transactions can start after thd_destructor_proxy observed that
trx_sys_any_active_transactions() did not hold.

row_update_for_mysql(): Remove the wrapper function and
rename the function from row_update_for_mysql_using_upd_graph().
Remove the unused parameter mysql_rec.

This is basically a duplicate or a reincarnation of MDEV-117.
For some reason, the test innodb.mdev-117 started failing in 10.2.

It is uncertain when this test started failing. The test is
nondeterministic, because there is a race condition between the
concurrently executing DELETE IGNORE and DELETE statements.

When a deadlock is reported for DELETE IGNORE, the SQL layer would
call handler::print_error() but then proceed to the next row,
as if no error had happened (which is the purpose of DELETE IGNORE).
So, when it proceeded to handler::ha_rnd_next(), InnoDB would hit an
assertion failure, because the transaction no longer exists, and we
are not executing at the start of a statement.

handler::print_error(): If thd_mark_transaction_to_rollback(thd, true)
was called, clear the ME_JUST_WARNING and ME_JUST_INFO errflags, so
that a note or warning will be promoted to an error if the transaction
was aborted by a storage engine.

        Check for duplicating keys added.

        The result_limit variable wasn't always initialized in
        Item_func_json_array::fix_length_and_dec().

        Comparison fixed to take the actual type of JSON value into
        account. Bug in escaping handling fixed.

The file wait_innodb_all_purged.inc waited for InnoDB purge in a way
that only worked in debug builds. The file wait_all_purged.inc
provides a better mechanism.

If the latest InnoDB redo log checkpoint was stored in the
first checkpoint slot and not the second one, InnoDB would
incorrectly set log_sys->log.lsn to the previous checkpoint.

It is possible that this logic error did not exist before
commit 86927cc7, which
removed traces of multiple InnoDB redo logs, to prepare for
MDEV-12548 (Mariabackup for MariaDB 10.2). In the worst case,
this error could mean that InnoDB unnecessarily fails to
recover from redo log when the last-but-one checkpoint was
overwritten, but the last checkpoint is intact.

recv_find_max_checkpoint(), recv_find_max_checkpoint_0():
Do not overwrite the fields of log_sys->log with the information
of an older checkpoint.

recv_find_max_checkpoint(): Do not return DB_SUCCESS on an error.

recv_recovery_from_checkpoint_start(): Return early if the log is
in a version-tagged format but not in the latest format. (In this case,
the log must be logically empty, and there is nothing to apply.)

Always read full page 0 to determine does tablespace contain
encryption metadata. Tablespaces that are page compressed or
page compressed and encrypted do not compare checksum as
it does not exists. For encrypted tables use checksum
verification written for encrypted tables and normal tables
use normal method.

Problem was introduced with the InnoDB 5.7 merge, the code related to
avoiding extra fsync at the end of commit when binlog is enabled. The
MariaDB method for this was removed, but the replacement MySQL method
based on thd_get_durability_property() is not functional in MariaDB.

This commit reverts the offending parts of the merge and adds a test
case, to fix the problem for InnoDB. But other storage engines are
likely to have a similar problem.

The debug flag recv_no_log_write prohibits writes of redo log records for
modifying page data. The debug assertion was failing when fil_names_clear()
was writing the informative MLOG_FILE_NAME and MLOG_CHECKPOINT records
which do not modify any data.

log_reserve_and_open(), log_write_low(): Remove the debug assertion.

log_pad_current_log_block(), mtr_write_log(),
mtr_t::Command::prepare_write(): Add the debug assertion.

During InnoDB startup, change buffer merge operations are prohibited
before recv_apply_hashed_log_recs(true), which performs the last phase
of redo log apply. Before this call, ibuf_init_at_db_start() would be
invoked, and it could trigger the debug assertion.

ibuf_init_at_db_start(): Do not declare the mini-transaction as
"inside change buffer", because nothing is being written in the
mini-transaction. The purpose of this function is only to initialize
the memory data structures from the persistent data structures.
