    Adjusted year(s) in copyright header 
    Added GPL copyright text

foreign->n_fields in order to preserve ON UPDATE CASCADE and
ON DELETE CASCADE flags.  For some reason, gcc does not warn about
shifting a 10-bit field to right by 24 bits.  (Bug #24741)

This bug was introduced while reducing the memory footprint of the
InnoDB data dictionary (Bug #20877).

innodb.test, innodb.result: Add a test case.

The variable is initialized to zero, and after that it is only added to.
Maybe the one who introduced the variable srv_buf_pool_flushed overlooked
that there is a separate return statement for returning ULINT_UNDEFINED?

is repeatedly called in buf_flush_free_margin() due to the definitions
of BUF_READ_AHEAD_AREA and other macros starting with BUF_READ_AHEAD_.

instead of three.

function can be called with "current_thd == NULL". Minor non-functional fix
in log0recv.c

adding a second parameter, adjust callers.

time fields

recv_recovery_from_checkpoint_finish(): Add 1 sec delay
before switching on the sync order checks in crash recovery, so that
file I/O threads have time to suspend themselves.

innobase_start_or_create_for_mysql(): Remove unnecessary delay now that
we moved the setting sync_order_checks_on=TRUE to log0recv.c,
to the start of the rollback phase in crash recovery.

Fix assertion failure sync0sync.c line 1239
(the latter ut_error in sync_thread_reset_level())
in crash recovery when UNIV_SYNC_DEBUG is enabled.

The change was accidentally committed with the merge in r1068.
This revision corresponds to r1051 with a properly merged
r1067 of branches/5.0.

The change was accidentally committed with the merge in r1068.

trx_rollback_for_mysql(), trx_commit_for_mysql():
Protect the creation of trx_dummy_sess with kernel_mutex.
This error was introduced in r1046 and r1050.

trx_rollback_for_mysql(): Fix the comment introduced in r1046.

trx_commit_for_mysql(): Use the dummy trx->sess also for committing a prepared
transaction in XA recovery, just in case our code would need the session
object also in that case (does not seem to need it right now).

trx_rollback_for_mysql(): Do not set trx->sess back to NULL.
This bug was introduced in r1046.

branches/5.0: trx_rollback_for_mysql(): Ensure that trx->sess is non-NULL
when calling trx_general_rollback_for_mysql().  This removes a segmentation
fault when rolling back a prepared transaction in XA recovery.  (Bug #21468)

the output of SHOW MUTEX STATUS in non-debug builds.  (Bug #24386)

#ifdef UNIV_SYNC_DEBUG to allow the code to be built
with UNIV_DEBUG but without UNIV_SYNC_DEBUG.

The code was previously unused in non-debug builds.

  Bug #24190  many exportable definitions of field_in_record_is_null
  
  mysql had several(2) exportable definitions of field_in_record_is_null function.
  
  Fixed with adding static.

  made static

the remaining print, add a comma so it doesn't get combined with the heap
size. Both problems were introduced in r383.

ha_innobase::rnd_pos(): Use correct format in DBUG_PRINT statements.

buf_page_release(): Remove the local variable buf_fix_count.

UT_LIST_REMOVE_CLEAR().

buf_LRU_invalidate_tablespace(): Invoke UT_LIST_GET_PREV(LRU, block)
before UT_LIST_REMOVE(LRU, buf_pool->LRU, block).

array while holding the mutex.  This removes the crash-triggering
race condition that was introduced when fixing Bug #15653.  (Bug #24089)

CPU-bound SELECT queries.  (Bug #15815)

Fix: replace the mutex by one mutex protecting the 'flush list'
(and the free list) and several mutexes protecting portions of the
buffer pool, where we keep several indivudual LRU lists of pages.

This patch is from Sunny Bains and Heikki Tuuri.

 Change return type of ha_innobase::info to int.

 plug.in: Add MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS.

dict_truncate_index_tree(): Replace parameter rec_t* rec with
btr_pcur_t* pcur.  Reposition pcur before calling btr_create().

sync_thread_add_level(): Remove the relaxation of the assertion added in r968.

order to be violated if the thread holds dict_operation_lock, whose level is
SYNC_DICT_OPERATION.  This removes the assertion failure of TRUNCATE TABLE
#ifdef UNIV_SYNC_DEBUG.

  Bug #22781: SQL_BIG_RESULT fails to influence sort plan
   Currently SQL_BIG_RESULT is checked only at compile time.
   However, additional optimizations may take place after
   this check that change the sort method from 'filesort'
   to sorting via index. As a result the actual plan
   executed is not the one specified by the SQL_BIG_RESULT
   hint. Similarly, there is no such test when executing
   EXPLAIN, resulting in incorrect output.
   The patch corrects the problem by testing for
   SQL_BIG_RESULT both during the explain and execution
   phases.

in the father page.

btr0btr.h: Add a BTR_MAX_LEVELS define.

instead of passing the wrong length to ut_print_namel().  (Bug #23368)

ut_print_name(), ut_print_namel(): Document the special treatment of '/'.

ut_print_namel(): Replace strchr() with memchr(), as the string might
not be NUL-terminated.

check thd->in_lock_tables but test if
thd->lex->sql_command == SQLCOM_LOCK_TABLES
instead.  Otherwise, stored functions will use table locks.  (Bug #18077)

This patch is from Heikki.
