Fix a bug where if you did a slow search that took too long to calculate
the page count, and you had 200 posts per page, then we would show page
5000 as the last page of the search.
This was because we were artificially returning 1,000,000 as the post
count to signal that the count timed out, but at 200 posts per page this
would show 5000 as the last page of the search.
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.
Fix a bug where generating thumbnails failed for certain images when
using libvips 8.10. Specifically, it failed for single-channel greyscale
images and four-channel CMYK images without an embedded color profile.
In these cases we specified an sRGB fallback profile, but under libvips
8.10 this failed because the sRGB profile was incompatible with
single-channel and four-channel images. Before libvips 8.10 this worked,
but as of 8.10 it's a hard error.
The way libvips handles fallback color profiles differs across versions,
so we have to use different arguments for different versions. In 8.7,
vips doesn't have builtin color profiles, so we have to specify our own
manually. In 8.9, it has builtin profiles, so we can omit the import
profile, but we're still required to set the export profile to sRGB,
otherwise it will leave CMYK images as CMYK when generating thumbnails.
In 8.10, we have to _not_ to set the import or export profile to sRGB,
otherwise it will fail with an incompatible profile error when it tries
to convert CMYK images to RGB.
The builtin sRGB profile used by libvips[1] is different than the one we
used previously[2]. The builtin one comes from LCMS[3], whereas ours
came from ArgyllCMS.[4] Not all sRGB profiles are created the same[5],
so this may result in some imperceptible differences in thumbnail
output. The ArgyllCMS profile was used before because it seemed to be
the best one[6], but realistically it probably doesn't matter.

Hardcode the list of nondisposable email providers instead of making it
a config option. Also add a few new providers.
This was previously a config option to keep it secret, but there's not
much need for secrecy here.
A Restricted user's email must be on this list to unrestrict their
account. If a user is Restricted and their email is not in this list,
then it's assumed to be disposable and can't be used to unrestrict their
account even if they verify their email address.
Generate smart previews as .png so we don't suffer recompression losses
when we convert the preview frame from a full size image down to a
150x150 .jpg thumbnail.
Fix regression in ef2857667 that caused animated GIFs and PNGs to
generate thumbnails that were larger than 150x150.
Also fix a bug with cropped previews not being generated for animated
GIFs and PNGs.
Remove StorageManager::Hybrid and StorageManager::Match. These were used
to store uploads on different servers based on the post ID or file
sample type. This is no longer used in production because in hindsight
it's a lot more difficult to manage uploads when they're fragmented
across different servers.
If you need this, you can do tricks with network filesystems to get the
same effect. For example, if you want to store some files on server A
and others on server B, then mount servers A and B as network
filesystems (with e.g. sshfs, Samba, NFS, etc), and use symlinks to
point subdirectories at either server A or B.
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.
Allow moderators to search `disapproved:<username>` with any user.
Before mods could only search for their own disapprovals, even though
they could see disapprovals by others.
Fix exception during https://danbooru.donmai.us/posts/random?tags=ordfav:nonamethanks
Before we were doing a query like this:
SELECT
"posts".*
FROM
"posts"
INNER JOIN
"favorites" ON "favorites"."post_id" = "posts"."id"
WHERE
(favorites.user_id % 100 = 64 AND favorites.user_id = 52664)
AND "posts"."id" = 343894
ORDER BY
favorites.id DESC,
posts.id DESC,
ID=343894 DESC
but `ID=? DESC` is ambiguous during an ordfav: search because of the
join on the favorites table. The fix is to qualify the reference as
`posts.id`.
Pundit 2.1.1 changed it so that if the first argument to `authorize` is
an Array, then the `authorize` call returns the last element of the
array. This broke order:random, because in that case we returned an
Array of posts. The fix is to return an ActiveRecord::Relation of posts,
which is more correct anyway.
Fix a regression introduced in rails/rails@4b1122c with the upgrade to Rails
6.1.4.1.
Triggered by a call to `SELECT * FROM ip_geolocations WHERE ip_addr in ...`.
A Rails refactoring changed the way that `WHERE ... IN ...` statements
worked, which had the side effect of passing a string value to our
IpAddressType serializer where before we expected a Danbooru::IpAddress
object.
Add support for using a proxy for HTTP requests. Only used for external
requests, such as downloading files or talking to source sites such as
Pixiv or Twitter, not for internal requests, such as talking to IQDB or
Reportbooru.
Parse the user agent and log whether it seems like a known bot or a
human to NewRelic under the `user.bot` request attribute. This is so
that known bots can be filtered out of search traffic analytics. Bots
and search crawlers make up a significant portion of search traffic.
* 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.
