Add Private Comments


This plugin lets you create comments which are only visible for users with a special permission. To create such a comment you need to check a checkbox with label "This comment is private" on the ticket page. If you leave the checkbox unchecked, then everybody can see the comment. The label is configurable.

Configuration Help

After installation of this plugin you will be prompted to update your Trac environment.

Then you are able to set the name of the permission in the admin-interface or in the trac.ini file. The default value is PRIVATE_COMMENT_PERMISSION.

You have to give this permission to all groups and users who should see the private comments.

If you want to change the color of the "This comment is private" message, you can do this by adding a CSS-class named "private_comment_marker" to your CSS stylesheets.

The label of the checkbox is modifiable via the CSS-class "private_comment_checkbox".

Bugs/Feature Requests

Old Comments

Old comments can't be set private, because they do not have an entry in the private_comment table. I created a script which creates the necessary entries in the private_comment table. Just place the script into your Trac context and run it.

Email notification

Email notifications are not filtered and, as far as I know, can't be filtered via a plugin. To filter the notifications I made some minor core changes. If a comment is private the text 'the ticket is processed internally' will be set as comment text.

You can install the filtering by using the notification_patch.patch file from svn.
