A variable XTRADB_PREFER_STATIC_LIBAIO should be set to 1 (or TRUE
or ON) for static linking.
Even if mysqld can avoid dependency on shared libaio, shared libraries
libmysqld.so or ha_innodb.so cannot link without it.
Given that the patch primarily addresses building tar.gz package, and
shared libraries mentioned above deemed less important than mysqld
executable, we accept shared lib dependency on libaio.so

CMakeLists.txt:
1. add -DSAFEMALLOC -DSAFE_MUTEX in the top-level CMakeLists.txt
don't force plugins to copy-paste these lines in their CMakeLists.txt
2.1 search plugin/* for plugins (not only storage/*),

2.3 extract library names from the plug.in (don't force library names to
be ha_<engine>.dll and <engine>.lib)

The reason for the long shutdown is hanging in io threads. It appears
that just closing completion port on XP does not necessarily signal
thread waiting in GetIOCompletionStatus() (even if this works fine
on later Windows versions)
The fix is to wakeup background threads using PostQueuedCompletionStatus()
with a special 'key' parameter indicating shutdown.
The reason for the crash is Innodb assertion after trying to load condition variables function
dynamically and not finding them
The fix is to skip dynamic loading if srv_use_native_conditions is FALSE. srv_use_native_conditions
is derived from Windows version and would be FALSE on XP and TRUE on later Windows.
This is the same handling as in MySQL 5.. In Maria 5.3 srv_use_native_conditions check was
presumably lost in the downporting.
The bug lp:798213 exposes a design flaw in --innodb-release-locks-early.
It does not work with InnoDB crash recovery, so it breaks transactional
integrety. So remove the feature.
map them to corresponding Windows CreateFile flags,
O_DSYNC=>FILE_FLAG_WRITE_THROUGH
ALL_O_DIRECT=>FILE_FLAG_NO_BUFFERING
Ability to specify innodb_flush_method=O_DSYNC fixes MySQL Bug#31876
(InnoDB commit performance slow on Windows XP), by removing an extra FlushFileBuffers()
call overhead.
Windows native async io is disabled.
The patch uses completion ports for asynchronous IO notification ,
instead of formerly used notification via event . This also removes
the limit of 64 async IOs per background IO thread (this limit was
forced by using WaitForMultipleObjects in previous AIO implementation)
The patch replaces the use of the POSIX I/O interfaces in mysys on Windows with
the Win32 API calls (CreateFile, WriteFile, etc). The Windows HANDLE for the open
file is stored in the my_file_info struct, along with a flag for append mode
(because the Windows API does not support opening files in append mode in all cases)
The default max open files has been increased to 16384 and can be increased further
by setting --max-open-files=<value> during the server start.
Noteworthy benefit of this patch is that it removes limits from the table_cache size -
allowing for more simultaneus users
A lot of small fixes and new test cases.
client/mysqlbinlog.cc:
Cast removed
client/mysqltest.cc:
Added missing DBUG_RETURN
include/my_pthread.h:
set_timespec_time_nsec() now only takes one argument
mysql-test/t/date_formats.test:
Remove --disable_ps_protocl as now also ps supports microseconds
mysys/my_uuid.c:
Changed to use my_interval_timer() instead of my_getsystime()
mysys/waiting_threads.c:
Changed to use my_hrtime()
sql/field.h:
Added bool special_const_compare() for fields that may convert values before compare (like year)
sql/field_conv.cc:
Added test to get optimal copying of identical temporal values.
sql/item.cc:
Return that item_int is equal if it's positive, even if unsigned flag is different.
Fixed Item_cache_str::save_in_field() to have identical null check as other similar functions
Added proper NULL check to Item_cache_int::save_in_field()
sql/item_cmpfunc.cc:
Don't call convert_constant_item() if there is nothing that is worth converting.
Simplified test when years should be converted
sql/item_sum.cc:
Mark cache values in Item_sum_hybrid as not constants to ensure they are not replaced by other cache values in compare_datetime()
sql/item_timefunc.cc:
Changed sec_to_time() to take a my_decimal argument to ensure we don't loose any sub seconds.
Added Item_temporal_func::get_time() (This simplifies some things)
sql/mysql_priv.h:
Added Lazy_string_decimal()
sql/mysqld.cc:
Added my_decimal constants max_seconds_for_time_type, time_second_part_factor
sql/table.cc:

sql/tztime.cc:
TIME_to_gmt_sec() now sets *in_dst_time_gap in case of errors
This is needed to be able to detect if timestamp is 0

my_getsystime() -> my_interval_timer()
- Added a lot of code comments
- Updated get_best_ror_intersec() to prefer index scan on not clustered keys before clustered keys.
- Use HA_CLUSTERED_INDEX to define if one should use HA_MRR_INDEX_ONLY
- For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered()
- Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect.

Updated get_best_ror_intersec() to ignore clustered keys.
Optimized away cpk_scan_used and one instance of current_thd (Simpler code)

sql/sql_select.cc:
Changed comment to #ifdef
For test of using index or filesort to resolve ORDER BY, use HA_CLUSTERED_INDEX flag instead of primary_key_is_clustered()
(Change is smaller than what it looks beause of indentation change)

Use HA_TABLE_SCAN_ON_INDEX instead of primary_key_is_clustered() to decide if ALTER TABLE ... ORDER BY will have any effect.
