2) Replaced it with a string field (state) which contains the state of the comment. i.e. published, unpublished, spam. Unsure if we want to create constants in comments.php to standardize the valid values... thoughts?
3) synchronized the spamfilter and comment unit tests with the current functionality
The comment block has changed to only display comments that are visible.
And there is code added to call the spam_filter helper if the spam_filter module is installed.
and XML for now, we have no driver for those technologies so anything
we implement is not going to be sufficiently tested and therefore
it'll be broken.
Change all comment functions to return JSON and update the JS to deal
purely with JSON. This is our new protocol for talking to the browser
and it should be flexible and portable.
Create comments.html.php. This duplicates comment.html.php, but will
be more efficient for rendering comments since we won't be creating a
new View for every comment we render.
