MySQL for Python MySQLdb-SVN

Missing file, but #1928858

Upped version to 3.0beta1.

Added test to make sure value is unicode before calling unicode_literal.

Spelling mistake in doc string.

Added version dependent call in _forceReconnection() to initialize the ping()
as a reconnecting command. This initialization is necessary with mysqldb
versions >= 1.2.2. It is only required once per connection instance as it is
persistent for the life of that instance.

Tons of changes from major refactoring/cleanup. This is all really broken
right now. In particular, all results are returned as strings.

In some cases sql_quote__() can be called before connect() (and thus no
_v_database_connection is set).

Added a check and connect() call if necessary.

Fixed an issue that MySQLdb versions previous to 1.2.2 had with Blob/Binary
types. It would convert them into character arrays instead of strings. Added version test and compatibility fix.

Upped version to 3.0alpha4.

Added joinTM.py which inherits from the standard ZRDB.TM and overrides its
_register() method to use the transaction's join() method directly. This avoids
a couple unnecessary abstraction levels and avoids some problems with the
overridden _register() and the transaction's register(). The former has a bare
except: that hides useful errors. The latter deals poorly with exceptions
raised from the join due to state modifications made before the join attempt.

This raises the Zope Dependency to Zope-2.8 or newer.

Changed the variables() method to be simpler and not hide errors.

Change a text exception to a class based one.
