Avoid doing one SQL query per topic when checking for new topics on the
forum index.
This also changes it so that forum topics aren't always marked as new
for anonymous users.
* Rarely used (only used ~15 times in total, not used at all since 2015-2016).
* Merging topics didn't properly bump the new topic.
* Merging topics didn't log a modaction when the old topic was deleted.
* Merging topics broke the old topic. Moving all the posts from one topic
to another leaves the old topic with zero posts. This normally can't
happen and it causes exceptions when you try to view the empty topic.
* It was technically possible to merge a topic with itself. This would
break the response_count.
* It was technically possible for a mod to merge a topic into an
admin-only topic.
Few people used forum subscriptions (only around 100), and even fewer
people were subscribed to active threads. Most subscriptions were for
old threads that will never be bumped again. The implementation also had
a few problems:
* Unsubscribe links in emails didn't work (they unset the user's
receive_email_notifications flag, but forum subscriptions didn't
respect this flag).
* Some users had invalid email addresses, which caused notifications to
bounce. There was no mechanism for preventing bounces.
* The implementation wasn't scalable. It involved a daily linear scan
over _all_ forum subscriptions looking for any topics that had been updated.
Few people used dmail filters (~900 users in 5 years) and even fewer
used them correctly. Most people used them to try to block dmail spam,
but usually they either blocked too much (by adding common words that
are present in nearly all dmails, causing all mails to them to be
filtered) or too little (blocking specific email addresses or urls,
which usually are never seen again after the spammer is banned).
Nowadays the spam detection system does a better job of filtering spam.
The use of any? and count was forcing new SQL requests for each statement.
Instead, present? and length were used which act on the reports once loaded.
Although unneeded, the comment and forum views were changed as well for consistency.
- Posts and topics have an added moderation_reports function
-- This is so all moderation reports can be loaded in a single query
- Those moderation reports are passed into the render functions separately
-- This is so the individual comments/posts don't have to be queried
- Limited to Builders+
-- Moderator+ can also use as they may be too busy ATM
- Only on users, comments, and forum posts
- Multiple reports can be generated per instance
- Primarily posts to a moderator-only topic for viewability
- Secondarily has a table for searchability
-- Viewable only by moderators
* Rename 'privacy mode' to 'private favorites'.
* Make the private favorites setting only hide favorites, not favgroups
and not the user's uploads on their profile page.
* Make the favgroup is_public flag default to true instead of false and
fix existing favgroups to be public if the user didn't have privacy mode
enabled before.
* List _all_ public favgroups on the /favorite_groups index, not just
favgroups belonging to the current user.
* Add a /users/<id>/favorite_groups endpoint.
- Fixes the extremely long class name on the post versions view
- Can now use one value instead of having to set th and td
- Added missing column classes on all tables
This was an alternate frontpage that contained a list of previews of the
most popular tags. This page was never linked from anywhere and it was
unknown by most users.
* Convert notices from helpers to partials.
* Eliminate PostSets::PostRelationship class in favor of post_sets/posts template.
* Eliminate COUNT(*) queries when calculating the number of child posts.
* Eliminate redundant parent load and parent exists queries.
Remove uses of the is_active flag. Keep column in database (for now).
The only purpose of this flag was to filter out pools from the pool list
in the Add to Pool dialog. This hasn't had much use since autocomplete
was added. Most pools didn't set the flag correctly anyway.
