Patch for BIT data types

[Waleed Abdulla]

I came across another bug that took a couple of hours to track. It's caused by MySql's BIT datatype, which is usually trouble anyway. Here is a possible fix in station.py. I wouldn't say it's the best way to fix it, but it worked for me. Note that I fixed the mysql-to-gae direction only. I haven't tested the gae-to-mysql direction yet.

def normalize_type(self, field_name, field_type):

    if field_name.endswith("_ref"):

        return TYPE_REFERENCE

    elif field_type.startswith("tinyint(1)") or field_type.startswith("bit"):

        return TYPE_BOOL

    elif field_type.startswith("varchar"):

        return TYPE_STR

    elif field_type.startswith("int") or field_type.startswith("tinyint"):

        return TYPE_INT 

    else:

        return field_type

def mysql_to_rocket(self, field_type, mysql_value):

    .....

    .....

    .....

    elif field_type == TYPE_BLOB:

        rocket_value = base64.b64encode(mysql_value)

    elif field_type == TYPE_BOOL and ord(mysql_value) < 2:  # field is of type BIT

        rocket_value = str(ord(mysql_value)).encode('utf-8')

    else:

        rocket_value = (u'%s' % mysql_value).replace('|', '&#124;').encode('utf-8')
