AttributeError: 'Connection' object has no attribute '_execute'

Hi,

i'm experiencing a strange behaviour meanwhile I try to deploy my
tornado app on my production server.

Let's me try to explain the situation.

I developed a little app that use mysql to store data and when I test
it on my laptop with python 2.6.3 and python-MySQLdb 1.2.3b2 there
were no problems, but as soon as I deploy my app on my production
server that uses python 2.6.2 and python-MySQLdb 1.2.2 the app fails
to render the page raising this error:

Traceback (most recent call last):
File "/usr/local/lib/python2.6/dist-packages/tornado/web.py", line
688, in _execute
getattr(self, self.request.method.lower())(*args, **kwargs)
File "/var/www/app.py", line 122, in get
self.store_db('cc',test)
File "/var/www/app.py", line 82, in store_db
self.db.execute(query)
File "/usr/local/lib/python2.6/dist-packages/tornado/database.py",
line 132, in execute
self._execute(cursor, query, parameters)
AttributeError: 'Connection' object has no attribute '_execute'

Any advice on how to fix this?


I'm using the latest revision of tornato made by Richard Taylor in
order to fix reconnect issuses.

I tried also to upgrade mysql-python to 1.2.3c but still no luck.

Db connections seems to work fine with self.db.get and self.db.query,
but as soon as I invoke a self.db.execute it hangs.

I test this also with a fresh unzipped copy of the demo blog source
but with still no luck in production.

I solved this moving form ubuntu i386 to ubuntu x64 it started working
fine.
