Thank you Mark. I'll give it a try.

You need something like

import re from Mailman import Utils from Mailman.Message import UserNotification NTEXT = """The text of the notification. """ NRECIP = 'recipient@example.com' NFROM = 'sender@example.com' NSUBJ = 'Notification subject'

def process(mlist, msg, msgdata): subject = Utils.oneline(msg['subject'], 'us-ascii') if re.search('.*rror.*', subject, re.IGNORECASE) nmsg = UserNotification(NRECIP, NFROM, NSUBJ, NTEXT) nmsg.send(mlist)

Hi Mark,

It seems the handler stops the list from working. When I delete the new pipeline the list works fine so it's the Python file (or the way I included it in the pipeline ?) that has a problem.

I've tried including a she-bang line or not (see below for both the handler and the text file used to shove it in the list pipeline), importing Message in addition to UserNotification and a few other things to no avail. One thing I find odd is that the handler doesn't get a .pyc file upon restart. Should I expect that or does it get created the first time it is invoked ?

I've copied the file over from a windows machine and I took care of chowning it so it has the same permissions as the other Handlers. The file looks ok in vi. What other options do I have before pdb ?

Thanx,

Yves Moisan

Hi Mark,

Our emails crossed here. I just tried importing my handler on the python prompt and the syntax error popped obvious. The minute the pipeline for the list was set with /bin/config_list I could see the pyc so I knew I was in business.

A final question : I see now that even restarting Mailman won't change the list-specific handler application and one needs to explicitly delete it if one wants to get rid of it. That's a good thing. But where are list-specific pipeline defs stored ?

Thanx!

The .pyc file will not get created until the handler is imported which does not happen until IncomingRunner handles a post for a list which has the handler in its pipeline.

Also, IncomingRunner is a python process which imports the handler, so no shebang line is required.

Check Mailman's error log.

Also, see below.

[...]

...

def process(mlist, msg, msgdata): subject = Utils.oneline(msg['subject'], 'us-ascii') if re.search('.*error.*', subject, re.IGNORECASE)

I misled you here. The above line needs to be

  if re.search('.*error.*', subject, re.IGNORECASE):

The missing colon results in a syntax error which causes all list posts to be shunted. There will be an error message and traceback in Mailman's error log. If the messages that were shunted are wanted, you can process them with Mailman's bin/unshunt. If not, remove them from qfiles/shunt.

Mark:

I had forgotten the ":" at the end of the if line.

Sorry for the noise.
