For a long time there was a discussion on whether to allow users to edit the comments after the post. Some people think that tampering with the comments is not a good idea, others think that such a feature is needed because users sometimes post sensitive information that should not be in the database.
We decided to compile the best from both worlds.
Now administrators are allowed to edit the comments, delete and upload files. If you are BUGtrack administrator, you'll see an "edit" icon in a comment header.
Clicking on that icon invokes administrative edit interface that should look familiar to BUGtrack users.
The only new element here is File(s) section which displays the list of files currently attached to a comment. Clicking on "Delete" icon will mark the file for removal from the database. Also, you can attach new files via familiar Upload file(s) control. Please note that there is no way to update the file – you should remove an old version and upload the new one, though you can do it in one step – the old file will be removed first and the new version will be uploaded.
After the changes are committed, revisions authors will be listed in the comments header. You can browse to any comment's version by clicking on numbers, let's say to revision 4
or to revision 5
or compare differences between adjacent revisions by clicking >> between revisions
"Diff" mode also displays the user and the timestamp of the change.
Non-admin users won't see an edit icon and will be always presented with the final version of the comment.
