Notifications not working, seems like the listeners are not being registered

[jon.stockdill@…]

I updated my tracdiscussion to:

URL: http://trac-hacks.org/svn/discussionplugin/0.11
Repository Root: http://trac-hacks.org/svn
Repository UUID: 7322e99d-02ea-0310-aa39-e9a107903beb
Revision: 6310
Node Kind: directory
Schedule: normal
Last Changed Author: Blackhex
Last Changed Rev: 6310
Last Changed Date: 2009-07-29 07:32:55 -0400 (Wed, 29 Jul 2009)

The notifications are still not working, seems like the listeners are not being registered.

I added:

self.log.error('self.message_change_listeners: ' + str(self.message_change_listeners))

to line 1167 of api.py and it prints: 2009-07-29 09:11:35,217 Trac[api] ERROR: self.message_change_listeners: []

I read ​http://trac.edgewall.org/wiki/TracDev/ComponentArchitecture but could not figure out how to get it registered. Is it a configuration issue or something else?

Let me know if there is anything I can do to help. I love the discussions and am excited about the notifications support.

Have you enabled notification component?

tracdiscussion.notification.* = enabled

[jon.stockdill@…]

Thanks! That helped. That wired it... and makes total sense after reading the component documentation. The log now says:

self.message_change_listeners: [<tracdiscussion.notification.DiscussionEmailNotification object at 0x8f26a0c>]

And I am getting the following error and stack trace now:

NameError: global name 'DiscussionApi' is not defined

Oh god, not aggain :-). What is your installation procedure? Try to install the plugin from scratch. Check the DEBUG log if all components are loading... Otherwise I don't know... This kind of error shouldn't happen.

I had a few eggs in site-packages, I removed all of them, built the egg from the HEAD of the 0.11 branch and restarted trac.

Here are the debug logs:

From: ​http://trac-hacks.org/wiki/DiscussionPlugin

tracdiscussion.notification.DiscussionNotifyEmail = enabled

doesn't load the DiscussionEmailNotification, so there are no listeners.

Changing it from:

tracdiscussion.notification.* = enabled

to

tracdiscussion.notification.DiscussionEmailNotification = enabled

Still generates the error:

NameError: global name 'DiscussionApi' is not defined

which makes sense.

My trac version is 0.11.2.1.

I appreciate the help and will continue to try and figure it out.

No, I appreciate your effort to investigate the problem.

Honestly, I really don't know where is the problem. Unforunatelly, I can't reproduce it until I know what server configuration are you using (OS, tracd, mod_python, Apache+CGI, Python version, etc.)? Just few shoots in the dark:

• Try to change line 17 in notification.py to from tracdiscussion.api import DiscussionApi
• Check content of plugin's egg, especially presence and content of api.py file (rename it to zip).
• Change line 204 in notification.py to api = api = DiscussionApi(self, context.req)
• Check or add to trac.ini tracdiscussion.api.DiscussionApi = enabled.

I'm not sure if anything of this may help, I'll ask on #trac IRC channel at freenode.org otherwise.

Ping?

[Ryan J Ollos]

Is it possible you have the AnnouncerPlugin installed?

[Radek Bartoň]

In that case it's duplicate of #7636.
