Charlie,

there are some tests in Lib/test/zxjdbc. Are they run in regrtest ? I
also saw a connection string pointing to bzimmer's localhost. So we
probably would need to setup a local java db
like hsqldb or derby ?

By the way, the problem went away:

Jython 2.2b2 on java1.6.0
>>> import com.ziclix.python.sql.zxJDBC
>>> connectString="jdbc:oracle:thin:@myhost:port:instance"
>>> db = com.ziclix.python.sql.zxJDBC.connect(connectString, "user",
"password", "oracle.jdbc.driver.OracleDriver")
>>> c = db.cursor()
>>> c
<PyExtendedCursor object instance at 1>
>>>

Thanks !
Oti.

Re: PyNone thrown when trying to get a cursor in zxJDBC

It was an old vs new style problem. I moved all of the PyBuiltinFunctionSet stuff over to the newstyle world so all of our types line up. That necessitated making PyBuiltinMethodSet newstyle as well. However, to be a new style method PyBuiltinMethodSet needs to be a descriptor and have a __get__ method to bind it to an instance. I left that out which lead to the reported errors. PyBuiltinMethodSet is only used in zxJDBC which is why we didn't see any more reports of it. I fixed it in r3248 so it should be good for rc1. Are there any tests for zxJDBC at all? This was a really simple error that running it at all would almost certainly catch.

I actually downloaded hsqldb last night thinking I would try setting up a test, it's good to know there already are some in Lib/test/zxjdbc. No reason we can't include the hsqldb jar in our test area and automatically run them - I believe it only requires the one jar and can even be run in memory if we don't want to hit the filesystem. -Frank ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
