Roundup Tracker

Alter your tracker's 'nosyreaction.py' detectors script to change the 'nosyreaction' function to be:

def nosyreaction(db, cl, nodeid, oldvalues):
   ''' A standard detector is provided that watches for additions to the
       "messages" property.

       When a new message is added, the detector sends it to all the users on
       the "nosy" list for the issue that are not already on the "recipients"
       list of the message.

       Those users are then appended to the "recipients" property on the
       message, so multiple copies of a message are never sent to the same
       user.

       The journal recorded by the hyperdatabase on the "recipients" property
       then provides a log of when the message was sent to whom.
   '''
   # send a copy of all new messages to the nosy list
   msgs = determineNewMessages(cl, nodeid, oldvalues)
   for msgid in msgs:
       try:
           cl.nosymessage(nodeid, msgid, oldvalues)
       except roundupdb.MessageSendError, message:
           raise roundupdb.DetectorError, message
   if not msgs:
       try:
           cl.nosymessage(nodeid, None, oldvalues)
       except roundupdb.MessageSendError, message:
           raise roundupdb.DetectorError, message

But a message for every change may be too much for you. Another route is to just require a message for certain changes. An example is to require a message when changing the 'assigned_to' field. Put the following code into an auditor to require that the users enters a message when changing the 'assigned_to' field:

if 'assigned_to' in new_values and 'messages' not in new_values :
    raise Reject, "Changing assigned_to requires a message"

Also, you can define a list of properties that will not trigger a notification when changed. If an update has a field not in the silent list, it will trigger a notification. This can be put at the top of nosyreaction():

  silent_fields = ['nosy'] # properties that don't notify when changed
  try:
      for v in oldvalues.keys():
          # loop over all changed properties
          # if any one of them is not in the silent list,
          # raise an exception to trigger sending a nosy message.
          # otherwise return without sending a message
          if v not in silent_fields:
             raise ValueError('found non-silent changed field')
          if v == 'nosy':
             # special case a particular property. E.G. if the
             # user performing the change (as reported by db.getuid)
             # added/removed themselves do not send a notification.
             # If some other change was done, simply raise an exception
             # to trigger a notification.
      return
  except ValueError:
      pass # we found a property that should be reported

  # do stuff to send nosy message
