Allow searching the /uploads and /media_assets pages by the following metatags:
* id:
* md5:
* width:
* height:
* duration:
* mpixels:
* ratio:
* filesize:
* filetype:
* date:
* age:
* status:<processing|active|deleted|expunged|failed> (for /media_assets)
* status:<pending|processing|active|failed> (for /uploads)
* is:<filetype>, is:<status>
* exif:
Examples:
* https://betabooru.donmai.us/media_assets?search[ai_tags_match]=filetype:png
* https://betabooru.donmai.us/uploads?search[ai_tags_match]=filetype:png
Note that in /uploads search, the id:, date:, and age: metatags refer to the upload media asset, not
the upload itself.
Note also that uploads may contain multiple assets, so for example searching uploads by
`filetype:png` will return all uploads containing at least one PNG file, even if they contain other
non-PNG files.
Upload files in natural order rather than archive order when uploading archive files.
Before files were listed in the same order they appeared in the zip file. This could be in
non-alphabetical order, or even with files from different directories interleaved between each
other. Now files are uploaded in natural order, which is alphabetical order but with numbers sorted
properly, so that `file-9.jpg` appears before `file-10.jpg`.
Allow uploading .zip, .rar, and .7z files from disk. The archive will be extracted and the images
inside will be uploaded.
This only works for archive files uploaded from disk, not from a source URL.
Post source URLs will look something like this: "file://foo.zip/1.jpg", "file://foo.zip/2.jpg", etc.
Sometimes artists uses Shift JIS or other encodings instead of UTF-8 for filenames. In these cases
we just assume the filename is UTF-8 and replace invalid characters with '?', so filenames might be
wrong in some cases.
There are various protections to prevent uploading malicious archive files:
* Archives with more than 100 files aren't allowed.
* Archives that decompress to more than 100MB aren't allowed.
* Archives with filenames containing '..' components aren't allowed (e.g. '../../../../../etc/passwd').
* Archives with filenames containing absolute paths aren't allowed (e.g. '/etc/passwd').
* Archives containing symlinks aren't allowed (e.g. 'foo -> /etc/passwd').
* Archive types other than .zip, .rar, and .7z aren't allowed (e.g. .tar.gz, .cpio).
* File permissions, owners, and other metadata are ignored.
Partial fix for #5340: Add support for extracting archive attachments from certain sources
Add ability to search your unposted uploads using AI tags. Like with
media assets, only basic tags are supported (no metatags) and complex
multi-tag searches will probably be slow.
The default AI tag confidence threshold is 50%. There's a hidden
search[min_score] URL param that lets you change this.
Sometimes uploads fail with this error:
Failed to replace upload_media_assets because one or more of the new
records could not be saved.
Change it so that media assets are saved individually, so that if saving
any of them fails we get a better error message.
Add a limit so that users can't upload more if they already have more
than 250 images queued for upload.
For example, if you upload a Pixiv post that has 200 images, then you'll
have 200 queued images for upload. This will go down as the images are
processed. If you exceed the limit, then trying to create new uploads
will return an error.
This is to prevent single users from overwhelming the site by uploading
too many images at once, thereby preventing other users from uploading
because the job queue is backed up and can't process new uploads by
other users until existing uploads are finished.
Introduce a Danbooru::URL class for dealing with URLs. This is a wrapper
around Addressable::URI that adds some additional helper methods. Most
significantly, the `parse` method only allows valid http/https URLs, and
it returns nil instead of raising an exception when the URL is invalid.
Allow uploading multiple files from your computer at once.
The maximum limit is 100 files at once. There is still a 50MB size limit
that applies to the whole upload. This limit is at the Nginx level.
The upload widget no longer shows a thumbnail preview of the uploaded
file. This is because there isn't room for it in a multi-file upload,
and because the next page will show a preview anyway after the files are
uploaded.
Direct file uploads are processed synchronously, so they may be slow.
API change: the `POST /uploads` endpoint now expects the param to be
`upload[files][]`, not `upload[file]`.
Make the upload page automatically detect when a source URL has multiple images
and let the user choose which images to post.
For example, when uploading a Twitter or Pixiv post with more than one image, we
direct the user to a page showing a thumbnail for each image and letting
them choose which ones to post.
This is similar to the batch upload page, except we actually download each image
in the background, instead of just hotlinking or proxying the thumbnails through
our servers. This avoids various problems with proxying and makes new features
possible, like showing which images in the batch have already been posted.
* Save the filename for files uploaded from disk. This could be used in
the future to extract source data if the filename is from a known site.
* Save both the image URL and the page URL for files uploaded from
source. This is needed for multi-file uploads. The image URL is the
URL of the file actually downloaded from the source. This can be
different from the URL given by the user, if the user tried to upload
a sample URL and we automatically changed it to the original URL. The
page URL is the URL of the page containing the image. We don't always
know this, for example if someone uploads a Twitter image without the
bookmarklet, then we can't find the page URL.
* Add a fix script to backfill URLs for existing uploads. For file
uploads, the filename will be set to "unknown.jpg". For source
uploads, we fetch the source data again to get the image and page
URLs. This may fail for uploads that have been deleted from the
source since uploading.
* uploads.media_asset_count - the number of media assets attached to this upload.
* upload_media_assets.status - the status of each media asset attached to this upload (processing, active, failed)
* upload_media_assets.source_url - the source of each media asset attached to this upload
* upload_media_assets.error - the error message if uploading the media asset failed
Mark old columns as ignored in preparation for dropping them. Make the
rating and tag_string nullable so they don't have to be set when
creating uploads and can be ignored too.
* Fix broken upload tests.
* Fix uploads to return an error if both a file and a source are given
at the same time, or if neither are given. Also fix the error message
in this case so that it doesn't include "base" at the start of the string.
* Fix uploads to percent-encode any Unicode characters in the source URL.
* Add a max filesize validation to media assets.
Fix the upload page so that it shows similar images (IQDB matches) for
files uploaded from your computer. Before this only worked for files
uploaded from a source.
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.
* Make it so replacing a post doesn't generate a dummy upload as a side effect.
* Make it so you can't replace a post with itself (the post should be regenerated instead).
* Refactor uploads and replacements to save the ugoira frame data when
the MediaAsset is created, not when the post is created. This way it's
possible to view the ugoira before the post is created.
* Make `download_file!` in the Pixiv source strategy return a MediaFile
with the ugoira frame data already attached to it, instead of returning it
in the `data` field then passing it around separately in the `context`
field of the upload.
Move more of the file-handling logic from UploadService and
StorageManager into MediaAsset. This is part of refactoring posts and
uploads to allow multiple images per post.
Hourly pruning of expired uploads was failing because of nil deference
errors in `media_asset.destroy!`. There are various cases where an
upload doesn't have a media asset, for example when the source url
fails to download or when the upload is of an invalid filetype.
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.
Flash is dead. It's no longer supported by browsers, it's not
well-supported by emulators, and only two Flash posts were uploaded in
the last year anyway. Old Flash files will continue to exist, but new
Flash uploads will no longer be allowed.
Add a Restricted user level. Restricted users are level 10, below
Members. New users start out as Restricted if they sign up from a proxy
or an IP recently used by another user.
Restricted users can't update or edit any public content on the site
until they verify their email address, at which point they're promoted
to Member. Restricted users are only allowed to do personal actions
like keep favorites, keep favgroups and saved searches, mark dmails as
read or deleted, or mark forum posts as read.
The restricted state already existed before, the only change here is
that now it's an actual user level instead of a hidden state. Before it
was based on two hidden flags on the user, the `requires_verification`
flag (set when a user signs up from a proxy, etc), and the `is_verified`
flag (set after the user verifies their email). Making it a user level
means that now the Restricted status will be shown publicly.
Introducing a new level below Member means that we have to change every
`is_member?` check to `!is_anonymous` for every place where we used
`is_member?` to check that the current user is logged in.
* Show completed uploads to other users.
* Don't show failed or incomplete uploads to other users.
* Don't show tags to other users.
* Delete completed uploads after 1 hour.
* Delete incomplete uploads after 1 day.
* Delete failed uploads after 3 days.
