[Zope3-dev] zope.app.rdb bug?

[David Johnson]

I am using the zope database adapter, and on occasion (1/20) the following
code intermittently throws an exception (1/20 times), even though the
connection is connected.  Am I doing something wrong or does someone know of
a bug here?

 

self.connection_base = zapi.getUtility(IZopeDatabaseAdapter, name)

query = "select * from orders where clientid=%s" %
(sqlquote(self.clientid))

print "stateConnected: %d" % (self.connection_base.isConnected())

result = queryForResults(self.connection_base(),query)

 

 

Results in the following debug code and exception (copied straight from my
output):

 

stateConnected: 1

2006-04-14T12:23:43 ERROR ZODB.Connection Shouldn't load state for 0x01b3
when the connection is closed
