When using concurrent insert with parallel index reads, it could
happen that reading sessions found keys that pointed to records
yet to be written to the data file. The result was a report of
a corrupted table. But it was false alert.

When inserting a record in a table with indexes, the keys are
inserted into the indexes before the record is written to the data
file. When the insert happens concurrently to selects, an
index read can find a key that references the record that is not
yet written to the data file. To avoid any access to such record,
the select saves the current end of file position when it starts.
Since concurrent inserts are always appended at end of the data
file, the select can easily ignore any concurrently inserted record.

The problem was that the ignore was only done for non-exact key
searches (partial key or using >, >=, < or <=).

The fix is to ignore concurrently inserted records also for
exact key searches.

No test case. Concurrent inserts cannot be tested with the test
suite. Test cases are attached to the bug report.

INSERT/DELETE/UPDATE followed by ALTER TABLE within LOCK TABLES
may cause table corruption on Windows.

That happens because ALTER TABLE writes outdated shared state
info into index file.

Fixed by removing obsolete workaround.

Affects MyISAM tables on Windows only.


myisam/mi_extra.c:
  On windows when mi_extra(HA_EXTRA_PREPARE_FOR_DELETE) is called,
  we release external lock and close index file. If we're in LOCK
  TABLES, MyISAM state info doesn't get updated until UNLOCK TABLES.
  
  That means when we release external lock and we're in LOCK TABLES,
  we may write outdated state info.
  
  As SQL layer closes all table instances, we do not need this
  workaround anymore.

  "Federated Denial of Service"
  Federated storage engine used to attempt to open connections within
  the ::create() and ::open() methods which are invoked while LOCK_open
  mutex is being held by mysqld. As a result, no other client sessions
  can open tables while Federated is attempting to open a connection.
  Long DNS lookup times would stall mysqld's operation and a rogue
  connection string which connects to a remote server which simply
  stalls during handshake can stall mysqld for a much longer period of
  time.
  This patch moves the opening of the connection much later, when the
  federated actually issues queries, by which time the LOCK_open mutex is
  no longer being held.

When the SQL_BIG_RESULT flag is specified SELECT should store items from the
select list in the filesort data and use them when sending to a client.
The get_addon_fields function is responsible for creating necessary structures
for that. But this function was allowed to do so only for SELECT and
INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for
the CREATE .. SELECT queries.

Now the get_addon_fields allows storing select list items in the filesort
data for the CREATE .. SELECT queries.

  "getGeneratedKeys() does not work with FEDERATED table"
  mysql_insert() expected the storage engine to update the row data
  during the write_row() operation with the value of the new auto-
  increment field. The field must be updated when only one row has
  been inserted as mysql_insert() would ignore the thd->last_insert.
  This patch implements HA_STATUS_AUTO support in ha_federated::info()
  and ensures that ha_federated::write_row() does update the row's
  auto-increment value.
  The test case was written in C as the protocol's 'id' value is
  accessible through libmysqlclient and not via SQL statements.
  mysql-test-run.pl was extended to enable running the test binary.

If a primary key is defined over column c of enum type then 
the EXPLAIN command for a look-up query of the form
  SELECT * FROM t WHERE c=0
said that the query was with an impossible where condition though the
query correctly returned non-empty result set when the table indeed 
contained rows with error empty strings for column c. 

This kind of misbehavior was due to a bug in the function 
Field_enum::store(longlong,bool) that erroneously returned 1 if
the the value to be stored was equal to 0. 
Note that the method 
Field_enum::store(const char *from,uint length,CHARSET_INFO *cs)
correctly returned 0 if a value of the error empty string 
was stored.

This bug manifested itself for join queries with GROUP BY and HAVING clauses
whose SELECT lists contained DISTINCT. It occurred when the optimizer could
deduce that the result set would have not more than one row.
The bug could lead to wrong result sets for queries of this type because
HAVING conditions were erroneously ignored in some cases in the function
remove_duplicates.

After dumping triggers mysqldump copied 
the value of the OLD_SQL_MODE variable to the SQL_MODE
variable. If the --compact option of the mysqldump was
not set the OLD_SQL_MODE variable had the value
of the uninitialized SQL_MODE variable. So
usually the NO_AUTO_VALUE_ON_ZERO option of the
SQL_MODE variable was discarded.

This fix is for non-"--compact" mode of the mysqldump,
because mysqldump --compact never set SQL_MODE to the
value of NO_AUTO_VALUE_ON_ZERO.

The dump_triggers_for_table function has been modified
to restore previous value of the SQL_MODE variable after
dumping triggers using the SAVE_SQL_MODE temporary
variable.

ORDER BY primary_key on InnoDB table

Queries that use an InnoDB secondary index to retrieve
data don't need to sort in case of ORDER BY primary key
if the secondary index is compared to constant(s).
They can also skip sorting if ORDER BY contains both the
the secondary key parts and the primary key parts (in
that order).
This is because InnoDB returns the rows in order of the
primary key for rows with the same values of the secondary
key columns.
Fixed by preventing temp table sort for the qualifying 
queries.
