Refactor full-text search on several tables (comments, dmails,
forum_posts, forum_topics, notes, and wiki_pages) to use to_tsvector
expression indexes instead of dedicated tsvector columns. This way
full-text search works the same way across all tables.
API changes:
* Changed /wiki_pages.json?search[body_matches] to match against only
the body. Before `body_matches` matched against both the title and the body.
* Added /wiki_pages.json?search[title_or_body_matches] to match against
both the title and the body.
* Fixed /dmails.json?search[message_matches] to match against both the
title and body when doing a wildcard search. Before a wildcard search
only matched against the body.
* Added /dmails.json?search[body_matches] to match against only the dmail body.
* Max comment length: 15,000 characters.
* Max forum post length: 200,000 characters.
* Max forum topic title length: 200 characters.
* Max dmail length: 50,000 characters.
* Max dmail title length: 200 characters.
Change error from "Body has no content" to "Body can't be blank" when a
user tries to submit an empty comment. This makes it consistent with
error messages in other models when someone tries to submit blank content.
Remove the rule that Members could only post 2 bumping comments per
hour.
This was frequently misunderstood as meaning that Members could only
post 2 comments per hour. In fact, Members could post an unlimited
number of comments per hour, but the rest of their comments had to be
non-bumping. The error message we showed to users was misleading. Even
our own code misunderstood what this did when describing the config
option.
Gold users also weren't subject to this limit, which was unfair since
Gold users aren't any better at commenting than regular users. The fact
that a large number of users already ignored bump limits and nobody
really noticed indicates that the limit was unnecessary.
Allow users to upvote a comment, then downvote it, without raising an
error or having to manually remove the upvote first. The upvote is
automatically removed and replaced by the downvote.
Changes to the /comment_votes API:
* `POST /comment_votes` and `DELETE /comment_votes` now return a comment
vote instead of a comment.
* The `score` param in `POST /comment_votes` is now 1 or -1, not
`up` or `down.`
* Add comment scores.
* Rework voting buttons so that you can click the upvote/downvote
buttons to toggle votes.
* Hide the edit, delete, undelete, and report buttons behind a popup menu.
* Show the upvote/downvote/reply buttons to logged out users. Redirect
them to the login page instead.
Previously thresholded comments were hidden completely. You had to click
the "Show X hidden comments" button to unhide all hidden comments in a
thread. Now it works like this:
* When a comment is below your threshold, the comment text is hidden and
replaced by a `[hidden]` link, which you can click to unhide the comment.
* When a comment is at half your threshold (for example, your threshold
is -8 but the comment is at -4), then the comment is greyed out.
This means that comments aren't completely hidden, they're just
collapsed, so you can see the commenter and the score without unhiding
the comment. It also means you don't have to scroll back up to unhide a
comment, and threads aren't disrupted by comments being secretly
hidden (which is confusing when people are replying to hidden comments,
which forces you to go back up and unhide to find).
Refactor how model visibility works in index actions:
* Call `visible` in the controller instead of in model `search`
methods. This decouples model visibility from model searching.
* Explicitly pass CurrentUser when calling `visible`. This reduces
hidden dependencies on the current user inside models.
* Standardize on calling the method `visible`. In some places it was
called `permitted` instead.
* Add a `visible` base method to ApplicationModel.
Remove various associated fields that were included by default on
certain endpoints. API users can use the only param to include the
full association if they need these fields.
* /artists.json: urls.
* /artist_urls.json: artist.
* /comments.json: creator_name and updater_name.
* /notes.json: creator_name.
* /pools.json: creator_name.
* /posts.json: uploader_name, children_ids, pixiv_ugoira_frame_data.
* /post_appeals.json: is_resolved.
* /post_versions.json: updater_name.
* /uploads.json: uploader_name.
- The only string works much the same as before with its comma separation
-- Nested includes are indicated with square brackets "[ ]"
-- The nested include is the value immediately preceding the square brackets
-- The only string is the comma separated string inside those brackets
- Default includes are split between format types when necessary
-- This prevents unnecessary includes from being added on page load
- Available includes are those items which are allowed to be accessible to the user
-- Some aren't because they are sensitive, such as the creator of a flag
-- Some aren't because the number of associated items is too large
- The amount of times the same model can be included to prevent recursions
-- One exception is the root model may include the same model once
--- e.g. the user model can include the inviter which is also the user model
-- Another exception is if the include is a has_many association
--- e.g. artist urls can include the artist, and then artist urls again
* Automatically generate a mod report when a comment, forum post, or
dmail is detected as spam.
* Automatically ban users that receive too many automatic spam reports
within a short window of time.
* Automatically mark spam dmails as deleted.
* Change ban threshold from 10 spam reports in 24 hours to 10 reports in 1 hour.
* Change ban length from 3 days to forever.
* Add ability to report dmails.
* Enable reports for comments, forum posts, and dmails.
* Allow Members to send reports.
* Don't allow users to report the same thing twice.
The belongs_to_creator macro was used to initialize the creator_id field
to the CurrentUser. This made tests complicated because it meant you had
to create and set the current user every time you wanted to create an
object, when lead to the current user being set over and over again. It
also meant you had to constantly be aware of what the CurrentUser was in
many different contexts, which was often confusing. Setting creators
explicitly simplifies everything greatly.
- 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
Replace the `method_attributes` and `hidden_attributes` methods with
`api_attributes`. `api_attributes` can be used as a class macro:
# include only the given attributes.
api_attributes :id, :created_at, :creator_name, ...
# include all default attributes plus the `creator_name` method.
api_attributes including: [:creator_name]
or as an instance method:
def api_attributes
[:id, :created_at, :creator_name, ...]
end
By default, all attributes are included except for IP addresses and
tsvector columns.
Comments have three states: visible, hidden, and invisible. Visible
comments are always shown. Hidden comments are not shown until the user
clicks 'Show all comments'. Invisible comments are never shown to the
user. Deleted comments are treated as hidden for moderators and
invisible for normal users. Thresholded comments are treated as hidden
for all users.
Certain parts of comment rendering triggered sql queries that we didn't
really need to do. Rework things to avoid this.
* Preload comment creators in order to display commenter names with link_to_user.
* Preload comment votes in order to display "undo vote" links. Only preload
votes for members since anonymous users can't vote and don't have "undo
vote" links.
* Rework various conditionals to do the filtering in Ruby so that we
avoid issuing any extra queries in sql.
* Avoid issuing any queries at all when the post doesn't have any
comments (when last_commented_at is blank).
Changes:
* Drop Users.id_to_name.
* Don't cache Users.name_to_id.
* Replace calls to name_to_id with find_by_name when possible.
* Don't autodefine creator_name in belongs_to_creator.
* Don't autodefine updater_name in belongs_to_updater.
* Instead manually define creator_name / updater_name only on models that need
to return these fields in the api.
id_to_name was cached to reduce the impact of N+1 query patterns in
certain places, especially in api responses that return creator_name /
updater_name fields. But it still meant we were doing N calls to
memcache. Using `includes` to prefetch users avoids this N+1 pattern.
name_to_id had no need be cached, it was never used in any performance-
sensitive contexts.
Avoiding caching also avoids the need to keep these caches consistent.
In rails 5, belongs_to associations automatically validate that the
associated item is present, meaning that we don't need to validate these
things manually any more.
Refactor various post_tag_match methods to use subqueries instead of joins.
This simplifies things inside PostQueryBuilder, since now we can assume
we're always dealing with a Post relation, rather than some other table
joined with the posts table.
