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.

In the ON UPDATE CASCADE clause of FOREIGN KEY constraints, the
calculated update vector was not fully initialized. This bug was
introduced in the InnoDB Plugin when implementing support for
ROW_FORMAT=DYNAMIC.

Additionally, the data type information was not initialized, but
apparently it has never been needed in this case.  Nevertheless, it is
not good programming practice to pass uninitialized values around.

calc_row_difference(): Declare the update field uninitialized in
Valgrind. Copy the data type information as well, except when the
field is SQL NULL. In the built-in InnoDB, initialize
ufield->extern_storage = FALSE (an initialization bug that had gone
unnoticed this far). The InnoDB Plugin and later have this flag to
dfield_t and have always initialized it properly.

row_ins_cascade_calc_update_vec(): Reduce the scope of some
pointers. Initialize orig_len. (This caused the bug in InnoDB Plugin
and later.)

row_ins_foreign_check_on_constraint(): Simplify a condition. Declare
the update vector uninitialized.

PARENT FOR OTHER ONE

Do not try to lookup key_nr'th key in 'table' because there may not be such
a key there. key_nr is the number of the key in the _child_ table name, not
in the parent table.

Instead just print the fields of the record that are covered by the first key
defined on the parent table.

This bug gets a better fix in MySQL 5.6, which is too risky for 5.1 and 5.5.

             BREAKS SOURCE RELEASE BUILD

Some of the required files were not getting copied while
performing 'make dist' and hence the build failed for
the created distribution source.

Added the missing files to Makefile.am.

btr_record_not_null_field_in_rec(): Remove the parameter rec.
Use rec_offs_nth_sql_null() instead of rec_get_nth_field().

               USING MYISAM_USE_MMAP ON WINDOWS

When OPTIMIZE/REPAIR TABLE is switching to new data file,
old data file is removed while memory mapping is still
active.

With 5.1 implementation of nt_share_delete() it is not
permitted to remove mmaped file.

This fix disables memory mapping for mi_repair() operations.

mysql-test/r/myisam.result:
  A test case for BUG#11757032.
mysql-test/t/myisam.test:
  A test case for BUG#11757032.
storage/myisam/ha_myisam.cc:
  mi_repair*() functions family use file I/O even if memory
  mapping is available.
  
  Since mixing mmap I/O and file I/O may cause various artifacts,
  memory mapping must be disabled.
storage/myisam/mi_delete_all.c:
  Clean-up: do not attempt to remap file after truncate, since
  there is nothing to map.
