Remove the last remaining uses of the PixivUgoiraFrameData model. As of
32bfb8407, Ugoira frame data is now stored in the MediaMetadata model,
under the `Ugoira:FrameDelays` EXIF field.
The pixiv_ugoira_frame_data table still exists, but it can be removed
after this commit is deployed.
Fixes#5264: Error when replacing with ugoira.
Allow moderators to forcibly change the username of other users. This is
so mods can change abusive or invalid usernames.
* A mod can only change the username of Builder-level users and below.
* The user can't change their own name again until one week has passed.
* A modaction is logged when a mod changes a user's name.
* A dmail is sent to the user notifying them of the change.
* The dmail does not send the user an email notification. This is so we
don't spam users if their name is changed after they're banned, or if
they haven't visited the site in a long time.
The rename button is on the user's profile page, and when you hover over
the user's name and open the "..." menu.
Fix it so that emails are (hopefully) able to show the one-click
unsubscribe button in Gmail and other mail providers that support the
List-Unsubscribe header. This way users can unsubscribe instead of
marking emails as spam.
* Add the List-Unsubscribe-Post header.
* Fix the disable email notifications endpoint to support POST as well as DELETE requests.
* Fix the disable email notifications endpoint to disable XSRF protection (we don't need
users to be logged in because we use a signed URL instead).
https://www.rfc-editor.org/rfc/rfc8058#section-3.1https://www.rfc-editor.org/rfc/rfc8058#section-8.1
* Add a global /post_events page that shows the history of all approvals,
disapprovals, flags, appeals, and replacements on a single page.
* Redesign the /posts/:id/events page to show all approval, disapproval,
flag, appeal, and replacement events for a single post (before it only
showed approvals, flags, and appeals).
* Remove the replacement history link from the post show page. Replacements
are now included in the post events page (closes#4948: Highlighed replacements).
* Add /post_approvals/:id and /post_replacements/:id routes (these are
used by the "Details" link on the post events page).
* Remove the /comment/search page. Instead put the comment search form
on the same page as the search results, so you don't have to go back
and forth to update your search.
* Add an "Edited?" search option, for finding comments that have been edited.
* Add options for sorting by oldest comments and lowest scoring comments.
Remove the /ip_addresses page. This page allowed moderators to search
users by IP, and to see recent activity tied to an IP. However, it was
limited to IPs tied to uploads, comments, dmails, artist edits, note
edits, and wiki edits.
Remove this page because it was limited in scope and because there are
better ways of doing what it did. The /user_events page is better at
catching sockpuppets because it tracks IPs for every login, not just for
certain types of edits. And the /user_actions page is better at
monitoring user activity because it shows all activity associated with
an account, not just for certain types of edits.
Removing this allows us to drop IP addresses from all tables besides the
user_events table. This is good because these IPs are no longer necessary
for any purpose, and because storing them forever is a liability.
Add a /user_actions page. This page shows you a global timeline of
(almost) all activity on the site, including uploads, comments, votes,
edits, forum posts, and so on.
The main things it doesn't include are post edits, pool edits, and
favorites (posts and pools live in a separate database, and favorites
don't have the timestamps we need for ordering).
This page is useful for moderation purposes because it lets you see a
history of almost all of a user's activity on a single page.
Currently this page is mod-only. In the future it will be open to all
users, so you can view the history of your own site activity, or the
activity of others.
Remove the IP address search option from the /moderator/dashboard page.
This was an obsolete way of searching for sockpuppet accounts by IP.
The /user_events page should be used instead.
Add "Add" and "Remove" buttons beneath thumbnails on the /ai_tags page.
These let you add the tag to the post if it's correct, or remove it if
it's wrong.
Add a database model for storing AI-predicted tags, and add a UI for browsing and searching these tags.
AI tags are generated by the Danbooru Autotagger (https://github.com/danbooru/autotagger). See that
repo for details about the model.
The database schema is `ai_tags (media_asset_id integer, tag_id integer, score smallint)`. This is
designed to be as space-efficient as possible, since in production we have over 300 million
AI-generated tags (6 million images and 50 tags per post). This amounts to over 10GB in size, plus
indexes.
You can search for AI tags using e.g. `ai:scenery`. You can do `ai:scenery -scenery` to find posts
where the scenery tag is potentially missing, or `scenery -ai:scenery` to find posts that are
potentially mistagged (or more likely where the AI missed the tag).
You can browse AI tags at https://danbooru.donmai.us/ai_tags. On this page you can filter by
confidence level. You can also search unposted media assets by AI tag.
To generate tags, use the `autotag` script from the Autotagger repo, something like this:
docker run --rm -v ~/danbooru/public/data/360x360:/images ghcr.io/danbooru/autotagger ./autotag -c -f /images | gzip > tags.csv.gz
To import tags, use the fix script in script/fixes/. Expect a Danbooru-size dataset to take
hours to days to generate tags, then 20-30 minutes to import. Currently this all has to be done by hand.
Add a system for upgrading accounts using upgrade codes. Users purchase
an upgrade code off-site then redeem it on-site to upgrade their account
to Gold. Upgrade codes are randomly pre-generated and are one time use
only. Codes have enough randomness that guessing a code is infeasible.
Fix the "My Uploads" page showing Admins all uploads, not just their own
uploads.
Changes the URL of the My Uploads page from /uploads to /users/:id/uploads.
This page shows each individual file you've uploaded. This is different
from the regular uploads page because files in multi-file uploads are
not grouped together.
Rework the upload process so that files are saved to Danbooru first
before the user starts tagging the upload.
The main user-visible change is that you have to select the file first
before you can start tagging it. Saving the file first lets us fix a
number of problems:
* We can check for dupes before the user tags the upload.
* We can perform dupe checks and show preview images for users not using the bookmarklet.
* We can show preview images without having to proxy images through Danbooru.
* We can show previews of videos and ugoira files.
* We can reliably show the filesize and resolution of the image.
* We can let the user save files to upload later.
* We can get rid of a lot of spaghetti code related to preprocessing
uploads. This was the cause of most weird "md5 confirmation doesn't
match md5" errors.
(Not all of these are implemented yet.)
Internally, uploading is now a two-step process: first we create an upload
object, then we create a post from the upload. This is how it works:
* The user goes to /uploads/new and chooses a file or pastes an URL into
the file upload component.
* The file upload component calls `POST /uploads` to create an upload.
* `POST /uploads` immediately returns a new upload object in the `pending` state.
* Danbooru starts processing the upload in a background job (downloading,
resizing, and transferring the image to the image servers).
* The file upload component polls `/uploads/$id.json`, checking the
upload `status` until it returns `completed` or `error`.
* When the upload status is `completed`, the user is redirected to /uploads/$id.
* On the /uploads/$id page, the user can tag the upload and submit it.
* The upload form calls `POST /posts` to create a new post from the upload.
* The user is redirected to the new post.
This is the data model:
* An upload represents a set of files uploaded to Danbooru by a user.
Uploaded files don't have to belong to a post. An upload has an
uploader, a status (pending, processing, completed, or error), a
source (unless uploading from a file), and a list of media assets
(image or video files).
* There is a has-and-belongs-to-many relationship between uploads and
media assets. An upload can have many media assets, and a media asset
can belong to multiple uploads. Uploads are joined to media assets
through a upload_media_assets table.
An upload could potentially have multiple media assets if it's a Pixiv
or Twitter gallery. This is not yet implemented (at the moment all
uploads have one media asset).
A media asset can belong to multiple uploads if multiple people try
to upload the same file, or if the same user tries to upload the same
file more than once.
New features:
* On the upload page, you can press Ctrl+V to paste an URL and immediately upload it.
* You can save files for upload later. Your saved files are at /uploads.
Fixes:
* Improved error messages when uploading invalid files, bad URLs, and
when forgetting the rating.
Fix regression introduced in 0db20e0ca. Setting `format: false` on the
wiki pages resource disabled format negotiation on all wiki page routes,
not just the show page, which meant /wiki_pages.json no longer worked.
The fix to monkey patch the internal Rails method that parses the file
extension from the URL, and have it ignore everything but the .html,
.json, .js, and .xml extensions. This is really hacky and may break in
future Rails releases.
* Add ability to mark moderation reports as 'handled' or 'rejected'.
* Automatically mark reports as handled when the comment or forum post
is deleted.
* Send a dmail to the reporter when their report is handled.
* Don't show the report notice on comments or forum posts when all
reports against it have been handled or rejected.
* Add a fix script to mark all existing reports for deleted comments,
forum posts, or dmails as handled.
Fix wiki pages like this returning 406 errors:
* https://danbooru.donmai.us/wiki_pages/rnd.jpg
Caused by Rails parsing the .jpg part as a file extension and trying to
return a JPEG in response. This happens deep in Rails' MIME negotiation
code, so it's hard to override. The fix is to pass `format: false` in
the route to disable all special handling of file extensions by Rails,
and then handle it ourselves in the controller. Ugly.
This only affected two tags: `rnd.jpg` and `haru.jpg`.
Allow admins to remove votes on posts. This is for fixing vote abuse.
Votes can be removed by going to the vote list on the /post_votes page,
or by clicking on a post's score, then using the "Remove" option in the
"..." dropdown menu next to the vote.
Votes are soft-deleted - they're marked as deleted in the database, but
not fully deleted. Removed votes are only visible to admins, not to
regular users. When a vote is removed by an admin, it leaves a mod
action.
Technically it's possible to undelete votes, but there's no UI for it.
Changes:
* Make it so you can click or hover over a post's favorite count to see
the list of public favorites.
* Remove the "Show »" button next to the favorite count.
* Make the favorites list visible to all users. Before favorites were
only visible to Gold users.
* Make the /favorites page show the list of all public favorites,
instead of redirecting to the current user's favorites.
* Add /posts/:id/favorites endpoint.
* Add /users/:id/favorites endpoint.
This is for several reasons:
* To make viewing favorites work the same way as viewing upvotes.
* To make posts load faster for Gold users. Before, we loaded all the
favorites when viewing a post, even when the user didn't look at them.
This made pageloads slower for posts that had hundreds or thousands of
favorites. Now we only load the favlist if the user hovers over the favcount.
* To make the favorite list visible to all users. Before, it wasn't
visible to non-Gold users, because of the performance issue listed above.
* To make it more obvious that favorites are public by default. Before,
since regular users could only see the favcount, they may have
mistakenly believed other users couldn't see their favorites.
Add a model for storing image and video metadata for uploaded files.
Metadata is extracted using ExifTool. You will need to install ExifTool
after this commit. ExifTool 12.22 is the minimum required version
because we use the `--binary` option, which was added in this release.
The MediaMetadata model is separate from the MediaAsset model because
some files contain tons of metadata, and most of it is non-essential.
The MediaAsset model represents an uploaded file and contains essential
metadata, like the file's size and type, while the MediaMetadata model
represents all the other non-essential metadata associated with a file.
Metadata is stored as a JSON column in the database.
ExifTool returns all the file's metadata, not just the EXIF metadata.
EXIF is one of several types of image metadata, hence why we call
it MediaMetadata instead of EXIFMetadata.
A MediaAsset represents an image or video file uploaded to Danbooru. It
stores the metadata associated with the image or video. This is to work
on decoupling files from posts so that images can be uploaded separately
from posts.
* Add README files to several directories in app/ giving a brief
overview of some parts of Danbooru's architecture.
* Add documentation for files in config/.
Replace the old IQDB API client with a new client for the new forked
version of IQDB at https://github.com/danbooru/iqdb.
Changes:
* The /iqdb_queries endpoint now returns `hash` and `signature` fields.
The `signature` is the full decoded Haar signature, while the `hash`
is a encoded version of the signature.
* The /iqdb_queries endpoint no longer returns `width` and `height`
fields in the response (these were always 128x128).
* We no longer need the IQDBs frontend server, now we talk to the IQDB
instance directly.
* We no longer send add/remove image commands to IQDB through AWS SQS,
now we send them to IQDB directly. They are sent in a delayed job so
that if IQDB is down, uploading images is still possible, the add
image commands will just get queued up.
* Fix a bug where regenerating an image's thumbnails didn't regenerate
IQDB, because IQDB silently ignored add image commands when the image
already existed in the database.
Allow admins to remove comment votes by other users. This is done by
clicking the comment score to get to the comment vote list, then
clicking the Remove button on every vote.
Allow users to view their own rate limits with /rate_limits.json.
Note that rate limits are only updated after every API call, so this
page only shows the state of the limits after the last call, not the
current state.
Add a new color palette and rework all site colors (both light mode and dark mode) to
use the new palette.
This ensures that colors are used consistently, from a carefully designed color palette,
instead of being chosen at random.
Before, colors in light mode were chosen on an ad-hoc basis, which resulted in a lot of
random colors and inconsistent design.
The new palette has 7 hues: red, orange, yellow, green, blue, azure (a lighter blue), and
purple. There's also a greyscale. Each hue has 10 shades of brightness, which (including
grey) gives us 80 total colors.
Colors are named like this:
var(--red-0); /* very light red */
var(--red-2); /* light red */
var(--red-5); /* medium red */
var(--red-7); /* dark red */
var(--red-9); /* very dark red */
var(--green-7); /* dark green */
var(--blue-5); /* medium blue */
var(--purple-3); /* light purple */
/* etc */
The color palette is designed to meet the following criteria:
* To have close equivalents to the main colors used in the old color scheme,
especially tag colors, so that changes to major colors are minimized.
* To produce a set of colors that can be used as as main text colors, as background
colors, and as accent colors, both in light mode and dark mode.
* To ensure that colors at the same brightness level have the same perceived brightness.
Green-4, blue-4, red-4, purple-4, etc should all have the same brightness and contrast
ratios. This way colors look balanced. This is actually a difficult problem, because human
color perception is non-linear, so you can't just scale brightness values linearly.
There's a color palette test page at https://danbooru.donmai/static/colors
Notable changes to colors in light mode:
* Username colors are the same as tag colors.
* Copyright tags are a deeper purple.
* Builders are a deeper purple (fixes#4626).
* Moderators are green.
* Gold users are orange.
* Parent borders are a darker green.
* Child borders are a darker orange.
* Unsaved notes have a thicker red border.
* Selected notes have a thicker blue (not green) border.
Require the user to re-enter their password before they can view,
create, update, or delete their API keys.
This works by tracking the timestamp of the user's last password
re-entry in a `last_authenticated_at` session cookie, and redirecting
the user to a password confirmation page if they haven't re-entered
their password in the last hour.
This is modeled after Github's Sudo mode.
Add the ability to restrict API keys so that they can only be used with
certain IP addresses or certain API endpoints.
Restricting your key is useful to limit damage in case it gets leaked or
stolen. For example, if your key is on a remote server and it gets
hacked, or if you accidentally check-in your key to Github.
Restricting your key's API permissions is useful if a third-party app or
script wants your key, but you don't want to give full access to your
account.
If you're an app or userscript developer, and your app needs an API key
from the user, you should only request a key with the minimum
permissions needed by your app.
If you have a privileged account, and you have scripts running under
your account, you are highly encouraged to restrict your key to limit
damage in case your key gets leaked or stolen.
* Add an explanation of what an API key is and how to use it.
* Make it possible for the site owner to view all API keys.
* Remove the requirement to re-enter your password before you can view
your API key (to be reworked).
* Move the API key controller from maintenance/user/api_keys_controller.rb
to a top level controller.
