[pysnmp-dev] error on NOTIFICATION-TYPE with OBJECTS

[Andrea N. <nic...@gm...>]

I Ilya.

I get serialization errors when I try to send notify with using definition
with nested object, also my object have the getValue redefine to have
dynamic resolution:

the mib is like:
...
snmpHeartbeatNotification NOTIFICATION-TYPE
    OBJECTS     { snmpHeartbeatRate }
    STATUS      current
    DESCRIPTION
        "This notification will typically be sent every
         30 seconds."
::= { snmpNotificationsPrefix 1 }
...

and the class has a method like that:

class Var(SuperClass):
        def readGet(self, name, *args):
            return name, self.syntax.clone(getValue())

above my fix:

on the same file there is also an error:
in the function sendNotification, line 170

you forgot to declare at function begin something like :

self.__pendingNotifications[metaSendPduHandle] = 0

so all the line like :

except error.StatusInformation:
   if not self.__pendingNotifications[metaSendPduHandle]

go in KeyError

to avoid the error is not better write like above?:

if metaSendPduHandle not in self.__pendingNotifications:
