Trac version upgrade to V1.2 causes mail notification function to fail

[Mingxing Tian]

I used the 1.0.13 version before the upgrade, where the mail notification service is normal, whenever the task status changes will be notified to the relevant colleagues. But after the upgrade, colleagues can not receive e-mail messages.

There is a strange phenomenon, the account will exist in the login will prompt, need to verify e-mail address. And colleagues can find their own mailbox verification code, so as to complete the e-mail address authentication. This also shows that a mailbox configuration should be successful.

To enable you to help me find a problem, I will log level down, the following record of a single task list to add a comment after the log, under normal circumstances should have to send mail notification action.

To facilitate query log files, I upload files through attachments.

I don't see any notification-related activity in your log message. For comparison, here are the log messages seen when updating a ticket with the preference //Never notify: I update a ticket//.

Do you have a Notification preferences tab at path /prefs/notification? If so, could you send a screen capture?


 

I'm assuming your [components] section is as described in (1), and your [notification] section is as described in (2). If different, please send.

I've found the problem because I didn't add the rules, I thought the default rule was ok, but by comparing your example, I finally found the reason. So, thank you very much.

But I still find a problem, when the mail format select "text/html", there will be an exception thrown.

It seems that the issue occurs after https://trac.edgewall.org/changeset/15075.

I just fixed it now. Please reinstall the latest of
https://trac-hacks.org/svn/trachtmlnotificationplugin/0.12.

I see. You should have found the [notification-subscriber] section added after upgrade to Trac 1.2. More information on configuring it can be found here:
