When there are no underlying tables specified for a merge table,
SHOW CREATE TABLE outputs a statement that cannot be executed. The
same is true for mysqldump (it generates dumps that cannot be
executed).

This happens because SQL parser does not accept empty UNION() clause.

This patch changes the following:
- it is now possible to execute CREATE/ALTER statement with
  empty UNION() clause.
- the same as above, but still worth noting: it is now possible to
  remove underlying tables mapping using ALTER TABLE ... UNION=().
- SHOW CREATE TABLE does not output UNION() clause if there are
  no underlying tables specified for a merge table. This makes
  mysqldump slightly smaller.

Problem: libedit is a very pure-ASCII oriented library,
and it is not aware of extended (0x80..0xFF) or even multi-byte
characters. It considered such characters as non-printable
and didn't allow to input them.
Fix: make libedit think that all bytes >= 0x80 are printable.

must match the order which they were declared in the class definition. 

The problem is that passing anything other than a integer to a limit
clause in a prepared statement would fail. This limitation was introduced
to avoid replication problems (e.g: replicating the statement with a
string argument would cause a parse failure in the slave).

The solution is to convert arguments to the limit clause to a integer
value and use this converted value when persisting the query to the log.

Disable the test case.

            log-slave-updates and circul repl

Slave SQL thread may execute one extra event when there are events
skipped by slave I/O thread (e.g. originated by the same server).
Whereas it was requested not to do so by the UNTIL condition.

This happens because we compare with the end position of previously
executed event. This is fine when there are no skipped by slave I/O
thread events, as end position of previous event equals to start
position of to be executed event. Otherwise this position equals to
start position of skipped event.

This is fixed by:
- reading the event to be executed before checking if the until condition
  is satisfied.
- comparing the start position of the event to be executed. Since we do
  not have the start position available, we compute it by subtracting
  event length from end position (which is available).
- if there are no events on the event queue at the slave sql starting
  time, that meet until condition, we stop immediately, as in this
  case we do not want to wait for next event.

The problem is that CREATE VIEW statements inside prepared statements
weren't being expanded during the prepare phase, which leads to objects
not being allocated in the appropriate memory arenas.

The solution is to perform the validation of CREATE VIEW statements
during the prepare phase of a prepared statement. The validation
during the prepare phase assures that transformations of the parsed
tree will use the permanent arena of the prepared statement.

 - fix test failures that was already there but now are
   more consistent when the 1 second sleep has been removed from

a table name.
  
The problem was that fill_defined_view_parts() did not return
an error if a table is going to be altered. That happened if
the table was already in the table cache. In that case,
open_table() returned non-NULL value (valid TABLE-instance from
the cache).
  
The fix is to ensure that an error is thrown even if the table
is in the cache.

by patch for bug 32265 .

Executing a prepared statement associated with a materialized
cursor yields to the client a metadata packet with wrong table
and database names. The problem was occurring because the server
was sending the the name of the temporary table used by the cursor
instead of the table name of the original table. The same problem
occurs when selecting from views, in which case the table name was
being sent and not the name of the view.
  
The solution is to fill the list item from the temporary table but
preserving the table and database names of the original fields. This
is achieved by tweaking the Select_materialize to accept a pointer to
the Materialized_cursor class which contains the item list to be filled.

            breaks replication

NAME_CONST() didn't replicate constant character set and collation
correctly.

With this fix NAME_CONST() inherits collation from the value argument.

- Replace per-thread signal()'s with  SetUnhandledExceptionFilter(). 
  The only remaining signal() is for SIGABRT (default abort()
  handler in VS2005 is broken, i.e removes user exception filter)
- remove MessageBox()'es  from error handling code
- Windows port for print_stacktrace() and write_core() 
- Cleanup, removed some unused functions

Check for an existing MySQL server package from a different vendor or
major MySQL version.  In such a case, refuse to install the server and
recommend how to safely remove the old packages before installing the
new ones.

Remove code from mysqlhotcopy which deals with the so-called "RAID"
feature of older MyISAM.

Federated may crash a server, return wrong result set, return
"ERROR 1030 (HY000): Got error 1430 from storage engine" message
when local (engine=federated) table has a key against nullable

The problem was wrong implementation of function that creates
WHERE clause for remote query from key.

Add -lmygcc to mysql_config output for libs, libs_r, and embedded_libs.

Required when linking against our static libs, if yassl is used, and gcc
used to build library is significantly different from that which is using
the library.
