Split requests made by Danbooru::Http into either internal or external
requests. Internal requests are API calls to internal services run by
Danbooru. External requests are requests to external websites, for
example fetching sources or downloading files. External requests may use
a HTTP proxy if one is configured. Internal requests don't.
Fixes a few source extractors not using the HTTP proxy for certain API calls.
Drop the typopro-web Javascript package that we used to import the Comic
Relief and Kalam fonts. Include these fonts directly in our own repo
instead. This drops a bunch of unnecessary Javascript dependencies.
Fixes Dependabot alerts about security issues in random Javascript
dependencies pulled in by the typopro-web package.
Update email validation rules to disallow the percent character (e.g.
`foo%bar@gmail.com`) and names ending with a period (e.g. `foo.@gmail.com`).
Names ending with a period are invalid according to the RFCs and cause
`Mail::Address.new` to raise an exception.
The percent character is technically legal, but only one email used it
and it was probably a typo.
Add config options to customize where uploads are stored, and how image URLs are generated.
* Add `media_asset_file_path` option to customize where uploads are stored.
* Add `media_asset_file_url` option to customize how image URLs are generated.
* Remove the `enable_seo_post_urls` config option. The `media_asset_file_url` option
should be used instead to include the tags in the image URL.
* Replace the "Download" placeholder thumbnail for Flash files with a
new placeholder that specifically says it's a Flash file.
* Fix a bug where the Flash placeholder thumbnail was too small when
using larger thumbnail sizes.
* Fix it so that media assets don't falsely consider Flash files to have
thumbnails. This could potentially cause errors if someone tried to
expunge, replace, or regenerate a Flash post.
* Make it an error to supply empty API credentials, like this:
`https://danbooru.donmai.us/posts.json?login=&api_key=`. Some clients
did this for some reason.
* Make it so that the `login` and `api_key` params are only allowed as
URL params, not as POST or PUT body params. Allowing them as body
params could interfere with the `PUT /api_keys/:id` endpoint, which
takes an `api_key` param.
When choosing the Open Graph image (the preview image shown when a
Danbooru link is posted on Discord or social media), choose the safest
image with the highest score, rather than the image with the highest
favcount.
Try to automatically fix various kind of typos and common mistakes in
email addresses when a user creates a new account. It's common for users
to signup with addresses like `name@gmai.com`, which leads to bounces
when we try to send the welcome email.
Possible fix for images not loading when Cloudflare Managed Challenges are enabled.
`crossorigin="anonymous"` prevents the `cf_clearance` cookie from being passed (maybe?).
Add support for uploading posts from Gelbooru. Note that the translated
tags will include both the Gelbooru tags and the tags from the Gelbooru
post's source. The commentary and artist information will also be taken
from the Gelbooru post's source. The source of the Danbooru post however
will be left as the Gelbooru post itself, not as the Gelbooru post's source.
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.
Automatically add the AI-generated tag to posts that have the
`PNG:Software=NovelAI` EXIF attribute.
This is not foolproof because this metadata may get removed if an
AI-generated post is resaved or uploaded to a site that strips EXIF
metadata. It also only works for NovelAI. Currently it detects 29 out of
177 AI-generated uploads on Danbooru.
Switch the Ugoira Javascript player to using frame delays from the
MediaMetadata model instead of from the PixivUgoiraFrameData model.
After this is deployed it will be safe to remove the PixivUgoiraFrameData
model.
Store Ugoira frame delays in the MediaMetadata model as a fake EXIF
field instead of in the PixivUgoiraFrameData model. This way we can get
rid of the PixivUgoiraFrameData model completely. This is a step towards
fixing #5264.
Remove various fallbacks and workarounds from the Ugoira Javascript
player for legacy browser issues.
* Remove fallbacks for URL, Blob, and ArrayBuffer (these have been
supported in most browsers for years).
* Remove workaround for iOS <6 not supporting Blob URLs.
* Remove workaround for a bug in Safari's handling of the Range HTTP
header. This was fixed in 2015.
* Remove support for playing a list of image URLs instead of playing
images from the .zip file (this was never used).
* Remove support for limiting loadahead of images (it was hardcoded to
always use unlimited loadahead anyways).
The frame data for Ugoira files is stored like this:
[{"file"=>"000000.jpg", "delay"=>65},
{"file"=>"000001.jpg", "delay"=>65},
{"file"=>"000002.jpg", "delay"=>65},
{"file"=>"000003.jpg", "delay"=>65},
{"file"=>"000004.jpg", "delay"=>65},
{"file"=>"000005.jpg", "delay"=>65},
{"file"=>"000006.jpg", "delay"=>65},
{"file"=>"000007.jpg", "delay"=>65},
{"file"=>"000008.jpg", "delay"=>65},
{"file"=>"000009.jpg", "delay"=>65},
{"file"=>"000010.jpg", "delay"=>65}]
This is stored in the pixiv_ugoira_frame_data table in YAML format. This
is a problem because a) we only need the frame delays to play the Ugoira,
not the filenames, and b) storing the data in YAML format is a security
issue that's blocking the upgrade to Rails 7.0.4 (see [1]).
This commit changes the Ugoira Javascript player so that it only uses
the list of frame delays, not the filenames, to play the Ugoira. This
paves the way for storing the frame delays as a simple integer array
instead as a serialized YAML object.
This assumes that the images in a Ugoira zip file are stored in the same
order they should be played back in. This was confirmed by checking every
zip file and verifying that files are actually stored in filename order.
