EXCEPTIONS-CLIENT from all the places.

Updated the README file.

Fix a regression (due to a typo) which caused spurious incorrect
argument errors for long data stream parameters if all forms of
logging were disabled (binary, general and slow logs).

Calculating the estimated number of records for a range scan
may take a significant time, and it was impossible for a user
to interrupt that process by killing the connection or the
query.

Fixed by checking the thread's 'killed' status in
check_quick_keys() and interrupting the calculation process if
it is set to a non-zero value.

  branches/5.0: Port fix for bug #49238 (Creating/Dropping a temporary
  table while at 1023 transactions will cause assert) from 5.1 to
  branches/5.1. Separate action for return value DB_TOO_MANY_CONCURRENT_TRXS
  from that of DB_MUST_GET_MORE_FILE_SPACE in row_drop_table_for_mysql().

The problem was that a user could supply supply data in chunks
via the COM_STMT_SEND_LONG_DATA command to prepared statement
parameter other than of type TEXT or BLOB. This posed a problem
since other parameter types aren't setup to handle long data,
which would lead to a crash when attempting to use the supplied
data.

Given that long data can be supplied at any stage of a prepared
statement, coupled with the fact that the type of a parameter
marker might change between consecutive executions, the solution
is to validate at execution time each parameter marker for which
a data stream was provided. If the parameter type is not TEXT or
BLOB (that is, if the type is not able to handle a data stream),
a error is returned.

           line exceeds the limit

The number and/or names of our files for the main test suite
(contents of "mysql-test/t/") now exceeds the command line
length limit on AIX.
Solve the problem by using separate "cp" commands for the
various file name extensions.

Reorder code breaks when finding tests skipped due to --skip-rpl etc.
Add simple test that master_opt is non-empty

Kill mysqltest and call mtr_kill_leftovers() before terminating

Addendum: Work around a compilation failure on Windows due to
          windows.h not being added to the global namespace.

The problem was that the bundled yaSSL library was being built
without thread safety support regardless of the thread safeness
of the compoments linked with it.

The solution is to enable yaSSL thread safety support if any
component (server or client) is to be built with thread support.

Also, generate new certificates for yaSSL's test suite.

The problem is in the Item_func_isnull::update_used_tables() function,
bracket is at the wrong place. Because of that isnull item erroneously
is treated as const item. The fix is to set brackets in the right place.

when an out-of-supported-range date is detected.

            
Some of the server implementations don't support dates later
than 2038 due to the internal time type being 32 bit.
Added checks so that the server will refuse dates that cannot
be handled by either throwing an error when setting date at 
runtime or by refusing to start or shutting down the server if 
the system date cannot be stored in my_time_t.

Problem: one with SELECT privilege on some table may dump other table
performing COM_TABLE_DUMP command due to missed check of the table name.

Fix: check the table name.

This fixes a recently introduced regression, where a variable is
not defined for the embedded server. Although the embedded server
is not supported in 5.0, make it at least compile.

      
MySQL handles the join syntax "JOIN ... USING( field1,
... )" and natural joins by building the same parse tree as
a corresponding join with an "ON t1.field1 = t2.field1 ..."
expression would produce. This parse tree was not cleaned up
properly in the following scenario. If a thread tries to
lock some tables and finds that the tables were dropped and
re-created while waiting for the lock, it cleans up column
references in the statement by means a per-statement free
list. But if the statement was part of a stored procedure,
column references on the stored procedure's free list
weren't cleaned up and thus contained pointers to freed
objects.
      
Fixed by adding a call to clean up the current prepared
statement's free list.

This is a backport from MySQL 5.1
