Abstract
Commenting allows registered users of a wiki to discuss a page's contents.
Goals
- Facilitate discussion of a page's contents
Requirements
- Do not allow HTML tags (yet)
- Can only be made by registered users
- Can be deleted by the commenter and any administrator
- When deleted, a placeholder comment is put into the comment list to prevent the "jump" of comment numbers
- Can only be edited by commenter
- When edited, the edited timestamp is displayed
- Appear in chronological order (oldest first)
- Only show X most recent comments, where X is defined by $wgCommentCount in Default/LocalSettings.php
- User has the option of viewing all comments on a page
- All functionality must work without Javascript being enabled
Configuration
| Config Key | Default Value | Description | Addtl notes |
| $wgCommentCount | 15 | Determines number of comments to display on initial page load | Setting to '0' disables commenting on the UI |
| $wgCommentCountAll | 10000 | Determines the number of comments to show when requesting 'ALL' comments | A high number is set in case there's a ridiculous number of comments so there's no timeouts from API or mySQL |
Enhancements for Lyons

1) will search be done against lucene or the database? If we hit the db directly, we should index cmnt_content (which is a text column :( )
2) if search by user, we need to index cmnt_poster_user_id
3) at some point we really need the API to start caching feeds
