innodb_buffer_pool_pages_total depends on page size. On Power8 it is 65k
compared to 4k on Intel. As we round allocations on page size we may get
slightly more memory for buffer pool.
Sort XA RECOVER as rows order depend on endianness.
XID cache is now based on lock-free hash.
Also fixed lf_hash_destroy() to call alloc destructor.
Note that previous implementation had race condition when thread was accessing
XA owned by different thread. This new implementation doesn't fix it either.
- ensure that mtr supressions table is flushed before doing controlled crash and restart
- use DBUG_SUICIDE() rather than abort() in partition tests - avoids a crash message/warning
- disable perfschema all_instances test on Windows- there are legitimate reasons for output to be different on Unix (some different threads, some different locks), the differences are expected to grow in the future, e.g with threadpool.
1. main.merge fails with errno 13 in copy_file().
The reason for the error is that copy_file tries to create a file with the same name as recently deleted one,
and there is still an open handle for the deleted file.
To fix, use my_delete_allow_opened() for MTR's delete_file. On Windows, this renames file to unique name
prior to deletion, and prevents EACCES errors for files opened with FILE_SHARE_DELETE.
2. innodb_bug59641
generates warnings, after server was killed and restarted in the test case.
The warnings are about test_suppression table (needs to be repaired, as it that was written just prior to the crash)
Fixed by using FLUSH TABLES after populating warning suppression table.

causes future shutdown hang
InnoDB would hang on shutdown if any XA transactions exist in the
system in the PREPARED state. This has been masked by the fact that
MySQL would roll back any PREPARED transaction on shutdown, in the
spirit of Bug #12161 Xa recovery and client disconnection.
[mysql-test-run] do_shutdown_server: Interpret --shutdown_server 0 as
a request to kill the server immediately without initiating a
shutdown procedure.
xid_cache_insert(): Initialize XID_STATE::rm_error in order to avoid a
bogus error message on XA ROLLBACK of a recovered PREPARED transaction.
innobase_commit_by_xid(), innobase_rollback_by_xid(): Free the InnoDB
transaction object after rolling back a PREPARED transaction.
trx_get_trx_by_xid(): Only consider transactions whose
trx->is_prepared flag is set. The MySQL layer seems to prevent
attempts to roll back connected transactions that are in the PREPARED
state from another connection, but it is better to play it safe. The
is_prepared flag was introduced in the InnoDB Plugin.
trx_n_prepared: A new counter, counting the number of InnoDB
transactions in the PREPARED state.
logs_empty_and_mark_files_at_shutdown(): On shutdown, allow
trx_n_prepared transactions to exist in the system.
trx_undo_free_prepared(), trx_free_prepared(): New functions, to free
the memory objects of PREPARED transactions on shutdown. This is not
needed in the built-in InnoDB, because it would collect all allocated
memory on shutdown. The InnoDB Plugin needs this because of
innodb_use_sys_malloc.
trx_sys_close(): Invoke trx_free_prepared() on all remaining
transactions.
