Category: None Group: Mailman 2.1 Status: Open Resolution: None Priority: 5 Submitted By: Richard Barrett (ppsys) Assigned to: Nobody/Anonymous (nobody) Summary: MM 2.0.13 to 2.1b5 upgrade fails

Initial Comment: make install when updating a MM 2.0.13 installation to 2.1b5 initally produced the following exception:

Updating mailing list: mailman Traceback (most recent call last): File "bin/update", line 569, in ? errors = main() File "bin/update", line 446, in main errors = errors + dolist(listname) File "bin/update", line 186, in dolist mlist = MailList.MailList(listname, lock=0) File "/mailman/run/Mailman/MailList.py", line 101, in __init__ self.Load() File "/mailman/run/Mailman/MailList.py", line 600, in Load self.CheckValues() File "/mailman/run/Mailman/MailList.py", line 650, in CheckValues for name, pattern, desc, emptyflag in self.topics: File "/mailman/run/Mailman/MailList.py", line 130, in __getattr__ raise AttributeError, name AttributeError: topics make: *** [update] Error 1

Having corrected the cause of this first exception the following exception was then encountered:

Upgrading from version 0x2000df0 to 0x20100b5 getting rid of old source files Updating mailing list: mailman Traceback (most recent call last): File "bin/update", line 569, in ? errors = main() File "bin/update", line 446, in main errors = errors + dolist(listname) File "bin/update", line 200, in dolist for addr, (reason, when) in mlist.delivery_status.items (): File "/mailman/run/Mailman/MailList.py", line 130, in __getattr__ raise AttributeError, name AttributeError: delivery_status make: *** [update] Error 1

These problems both seem to arise because of the following:

1. The MailList class is derived from the classes TopicMgr and Bouncer (amongst others).

2. The MailList __init__ function calls the __init__ functions of its superclasses if they have that function; which they do not in the case of the of TopicMgr and Bouncer classes

3. The MailList __init__ function calls its own InitTempVars function which in turn calls the InitTempVars functions of MailList's superclasses if they have that function; which they do not in the case of the of class TopicMgr and Bouncer classes

4. The MailList __init__ function does not call the InitVars functions of the TopicMgr and Bouncer classes which is why self.topics and self.delivery_status are undefined attributes of the MailList instance being created; these being instance variables introduced by MM 2.1b5 and missing from MM 2.0.13 instance of the MailList class which is what is being dealt with at the time the update is being done.

Adding the following definition to the TopicMgr and Bouncer class definitions seem to clear the problem although whether this is the best log-tem solution is questionable:

InitTempVars = InitVars
