For GCov builds, if the server crashes, the normal exit handler for writing
coverage information is not executed due to the abnormal termination.

Fix this by explicitly calling the __gcov_flush function in our crash handler.

Dropping an user defined function may cause server crash in
case this function is still in use by another thread.

The problem was that our hash implementation didn't update
hash link list properly when hash_update() was called.


mysys/hash.c:
  The following requirement wasn't met by hash_update() function
  causing corruption of hash links list:
  
  After a record was unlinked from the old chain during update, it
  holds random position. By the chance this position is equal to
  position for the first element in the new chain. That means
  updated record is the only record in the new chain.

length of the result values was truncated to the
CHAR_LENGTH of the original UTF8 value.

  Fixed bug #29205.
  The calculation of data length was modified in
  the Item_type_holder::join_types method to take into

spaces.

When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.

Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.

query / no aggregate of subquery
 The optimizer counts the aggregate functions that 
 appear as top level expressions (in all_fields) in 
 the current subquery. Later it makes a list of these
 that it uses to actually execute the aggregates in
 end_send_group().
 That count is used in several places as a flag whether
 there are aggregates functions.
 While collecting the above info it must not consider
 aggregates that are not aggregated in the current 
 context. It must treat them as normal expressions 
 instead. Not doing that leads to incorrect data about
 the query, e.g. running a query that actually has no
 aggregate functions as if it has some (and hence is
 expected to return only one row).
 Fixed by ignoring the aggregates that are not aggregated
 in the current context. 
 One other smaller omission discovered and fixed in the 
 process : the place of aggregation was not calculated for
 user defined functions. Fixed by calling 
 Item_sum::init_sum_func_check() and 
 Item_sum::check_sum_func() as it's done for the rest of 
 the aggregate functions.

  "Federared Transactions Failure"
  Bug occurs when the user performs an operation which inserts more than 
  one row into the federated table and the federated table references a 
  remote table stored within a transactional storage engine. When the
  insert operation for any one row in the statement fails due to 
  constraint violation, the federated engine is unable to perform 
  statement rollback and so the remote table contains a partial commit. 
  The user would expect a statement to perform the same so a statement 
  rollback is expected.
  This bug was fixed by implementing  bulk-insert handling into the
  federated storage engine. This will relieve the bug for most common
  situations by enabling the generation of a multi-row insert into the
  remote table and thus permitting the remote table to perform 
  statement rollback when neccessary.
  The multi-row insert is limited to the maximum packet size between 
  servers and should the size overflow, more than one insert statement 
  will be sent and this bug will reappear. Multi-row insert is disabled
  when an "INSERT...ON DUPLICATE KEY UPDATE" is being performed.
  The bulk-insert handling will offer a significant performance boost 
  when inserting a large number of small rows.
This patch builds on Bug29019 and Bug25511

  "Federated INSERT failures"
  Federated does not correctly handle "INSERT...ON DUPLICATE KEY UPDATE"
  However, implementing such support is not reasonably possible without
  increasing complexity of the storage engine: checking that constraints
  on remote server match local server and parsing error messages.
  This patch causes 'ON DUPLICATE KEY' to fail with ER_DUP_KEY message
  if a conflict occurs and not to fail silently.

SHOW CREATE TABLE or SELECT FROM I_S.

Actually, the bug discovers two problems:
  - the original query is not preserved properly. This is the problem
    of BUG#16291;
  - the resultset of SHOW CREATE TABLE statement is binary.

This patch fixes the second problem for the 5.0.

Both problems will be fixed in 5.1.

sql/item.h:
  Use utf8_general_ci instead of binary collation by default,
  because for views and base tables utf8 is the character set
  in which their definition is stored. For system constants
  it's the default character set, and for other objects
  (routines, triggers), no character set is stored, and
  therefore no character set is known, so returning utf8
  is just as good as any non-binary character set.
  This latter problem is fixed in 5.1 by 16291. In 5.1
  we will return the "real" character set.

Problem: like_range() returned wrong ranges for contractions (like 'ch' in Czech').
Fix: adding a special code to handle tricky cases:
- contraction head followed by a wild character
- full contraction
- contraction part followed by another contraction part,
  but they are not a contraction together.
