  This test requires utf8
mysql-test/suite/innodb_plugin/t/innodb_mysql.test:
  This test requires Xtradb
sql/sql_base.cc:
  Don't print table names for placeholders.
sql/sql_show.cc:
  Temporary fix:
  Save and restore db and table_name in mysqld_show_create (to get rid of valgrind warning)
  A better solution that needs to be investgated is to not change these fields in mysql_derived_prepare()
sql/sql_view.cc:
  Fixed valgrind warning
storage/xtradb/handler/ha_innodb.cc:
  Don't access THD directly

mysql-test/lib/My/Options.pm:
  My::Options::is_set() now matches both option names and values!
mysql-test/lib/mtr_cases.pm:
  1. don't merge --plugin-load here, it's too early
  2. don't skip combinations that set --plugin-load just because the test needs another --plugin-load.
     Skip *only* if test's --plugin-load matches *exactly* --plugin-load of one of the combinations.
  3. if skipping all combinations but one, still assign the test to the combination
mysql-test/mysql-test-run.pl:
  1. remove dead code - don't set variables that aren't used.
  2. bugfix: allow one-letter combination names
  3. in the command line, merge all --plugin-load options in one
storage/federated/ha_federated.cc:
  bugfix: garbage character in the generated SELECT query

We merged the test case for this into MariaDB 5.1, but the fix
was not yet part of XtraDB.

The title is misleading. This bug was actually introduced by
bug 12635227 and was unearthed by a later optimization.
We need to free buf_page_t structs that we are allocating using
malloc() at shutdown.

The bug was accidentally fixed by fixing
Bug#11759688 52020: InnoDB can still deadlock on just INSERT...ON DUPLICATE KEY
a.k.a. the reintroduction of
Bug#7975 deadlock without any locking, simple select and update

a.k.a. Bug#7975 deadlock without any locking, simple select and update

Bug#7975 was reintroduced when the storage engine API was made
pluggable in MySQL 5.1. Instead of looking at thd->lex directly, we
rely on handler::extra(). But, we were looking at the wrong extra()
flag, and we were ignoring the TRX_DUP_REPLACE flag in places where we
should obey it.

innodb_replace.test: Add tests for hopefully all affected statement
types, so that bug should never ever resurface. This kind of tests
should have been added when fixing Bug#7975 in MySQL 5.0.3 in the
first place.

btr_pcur_restore_position_func(): When the cursor was positioned at
the tree infimum or supremum, initialize pos_state and latch_mode. The
assertion failed, because pos_state was BTR_PCUR_WAS_POSITIONED.  In
the test failure of WL#5874, the purge thread attempted to restore the
cursor position on the infimum record (the clustered index was empty).

btr_pcur_detach(), btr_pcur_is_detached(): Unused functions, remove.

In all callers of row_sel_convert_mysql_key_to_innobase(), assert
that the converted key is empty or nonempty when it should be.

Also fixed possibly uninitialized use of need_copy_table_res.

Fixed my_gethwaddr.c to allow compilation on Mac OS X.

row_rename_table_for_mysql(): Return DB_ERROR instead of DB_SUCCESS
when fil_rename_tablespace() returns an error. This bug was introduced
in the InnoDB Plugin.

Bug#12612184 RACE CONDITION AFTER BTR_CUR_PESSIMISTIC_UPDATE()

The fix introduced potentially more severe crash recovery problems
than the bug causes. Revert the fix for now.

This was an attempt to address problems with the Bug#12612184 fix.
Even with this follow-up fix, crash recovery can be broken.
Let us fix the bug later.
