query:
- When subquery is located in ORDER BY, EXPLAIN will run as follows:
  select_describe() will run JOIN::prepare()/optimize() for the subquery;
  then at some point subselect_single_select_engine::prepare() will be called,
  which will create another join and run join->prepare().

  In mainline mysql this is not a problem because subquery's join will be 
  destroyed after the first call. 
  In MariaDB, it won't (table elimination needs to keep JOIN objects around
  for longer in order to know which tables were eliminated when constructing
  EXPLAIN EXTENDED warning).

  Fix the problem of memory leak by calling select_lex->cleanup() in 
  subselect_single_select_engine::prepare().

Bug#46949: memory leak with failed alter table to create partitions based on extract()

Bug#51830: Incorrect partition pruning on range partition (regression)

sql/item_subselect.cc:
    Fixed valgrind failure in select_describe(), read of uninitialized 
    Item_subselect::eliminated: 
    - it turns out we can call select_describe() without having fixed 
      subquery items for child subselects. These are not the kind of subqueries
      that we could eliminate, so the fix is to ensure that 
      item_subselect->eliminated==FALSE even before fix_fields is called.
      Also added code to reset item_subselect->eliminated back to FALSE in
      Item::reset() call.

Save no-records constant tables in JOIN::const_table_map before we invoke

  Save no-records constant tables in JOIN::const_table_map before we invoke eliminate_tables(). Failure to do so caused crash when the same table was marked as constant two times.

(Problem was missing time_zone setting)

- When analying multiple equalities, take into account that they 
  may not have a single table field that belongs to one of the tables
  that we're trying to eliminate (and they are not useful for table
  elimination in that case)

  Updated test results
mysql-test/suite/maria/t/maria3.test:
  Don't show maria_used_for_temp_tables, as it's value is depending on configure options

Now mysqld --help --verbose shows the value for thread-handling
Fixed also that mysqld --one-thread works as expected.

When one does a drop table, the indexes are not flushed to disk before drop anymore (with MyISAM/Maria)
myisam-recover options changed from OFF to 'DEFAULT' to get less change of data loss when using MyISAM.
(The disadvantage is that changed MyISAM tables will be checked at access time; Use --myisam-recover=OFF for old behavior)
Don't call extra(HA_EXTRA_FORCE_REOPEN) in ALTER TABLE if table is locked as this will mark table as crashed!
Added assert to detect if we accidently would use MyISAM versioning in MySQL

This allows one to send an extra command to the mysql server to setup the environment before starting tests.

path names than 99 characters, using the USTAR format of the
resulting source TAR.

To be able to specify the use of USTAR when creating the source
TAR, we needed both to update the GNU autotools version requirements
slightly, and update the initiation of the tools to use more
modern constructs.

The test case rpl_binlog_corruption fails on windows because when
adding a line to the binary log index file it gets terminated
with a CR+LF (which btw, is the normal case in windows, but not on
Unixes - LF). This causes mismatch between the relay log names,
causing mysqld to report that it cannot find the log file.

We fix this by creating the instrumented index file through
mysql, ie, using SELECT ... INTO DUMPFILE ..., as opposed on
relying on ultimatly OS commands like: -- echo "..." >
index. These changes go into the file and make the procedure
platform independent:

  include/setup_fake_relay_log.inc

Side note: when using SELECT ... INTO DUMPFILE ..., one needs to
check if mysqld is running with secure_file_priv. If it is, we do
it in two steps: 1. create the file on the allowed location;
2. move it to the datadir. If it is not, then we just create the
file directly on the datadir (so previous step 2. is not needed).

resulution of bug #46895.

            REVOKE/GRANT; ALTER EVENT.

The following statements support the CURRENT_USER() where a user is needed.
  DROP USER 
  RENAME USER CURRENT_USER() ...
  GRANT ... TO CURRENT_USER()
  REVOKE ... FROM CURRENT_USER()
  ALTER DEFINER = CURRENT_USER() EVENT
but, When these statements are binlogged, CURRENT_USER() just is binlogged
as 'CURRENT_USER()', it is not expanded to the real user name. When slave 
executes the log event, 'CURRENT_USER()' is expand to the user of slave 
SQL thread, but SQL thread's user name always NULL. This breaks the replication.

After this patch, All above statements are rewritten when they are binlogged.
The CURRENT_USER() is expanded to the real user's name and host.

Fix for Bug#31173: mysqlslap.exe crashes if called without any parameters

.bzrignore:
  Fixed .bzrignore rules. Many were simply not ignoring what they were meant to.
client/mysqlslap.c:
  Fixed bug for Bug#31173: mysqlslap.exe crashes if called without any parameters
  The original patch could cause memory leaks and odd problems depending on how connection was made.
  This code ensures that all mysql_options() are set for each mysql_real_connect().
  (This patch by Monty)
mysys/my_thr_init.c:
  Fixed multiply-initialized critical section on Windows, due to code incorrectly
  checking the wrong field in an attempt to prevent multiple-initialization.
sql-common/client.c:
  Don't use shared memory if it's not set (for example after failed mysql_real_connect).
  Ensure that mysql_close() resets all resources so that it's safe to call it twice.
  (Patch by monty, related to Bug#31173: mysqlslap.exe crashes if called without any parameters)
sql/CMakeLists.txt:
   Added page fault counters for SHOW PROFILE on Windows.
sql/mysqld.cc:
  Fixed attempt to set a NULL event. The code now only sets the event if appropriate (i.e. shared memory is being used)
sql/sql_profile.cc:
  Added page fault counters for SHOW PROFILE on Windows.
sql/sql_profile.h:
  Added page fault counters for SHOW PROFILE on Windows.
sql/udf_example.def:
  Some cleanup functions were not exported from udf_example.dll, causing them to
  never be executed, and as a result multiple-initialization of kernel objects
  occurred and resources were not being freed correctly.
storage/maria/ma_close.c:
  Condition variable share->key_del_cond was never being destroyed, while its
  containing heap block was being freed in maria_close(), leaking kernel
  resources.

Updated the certs to expire on 2015. 
Made sure they work with both yassl and openssl.
