Autotag non-web_source on posts that have a non-http:// or https:// URL.
Add a fix script to backfill old posts.
Syntactically invalid URLs are still considered web sources. For
example, `https://google,com` technically isn't a valid URL, but it's
not considered a non-web source.
When a banned artist tag is aliased into a nonbanned artist tag, move
the is_banned flag from the old artist entry to the new artist_entry.
Related to #4940. Fixes a case where a banned artist could lose the
banned status when it was moved.
Fix an `ActionView::Template::Error: undefined method 'verification_key'
for nil` error in the welcome_user mailer when a user signs up without
an email address.
Caused by the fact that we now render mail templates regardless of
whether the user has an email address, and then skip sending the email
only after the mail template is rendered.
Fix mailers to not attempt deliveries to invalid or nonexistent email
addresses. This usually happened when someone changed their email, and
we tried to send a confirmation email to a nonexistent address.
Remove the ability to lock a tag's category. Before a moderator could
lock a tag such that only an admin could change the tag's category.
Nowadays the ability to change a tag's category is based on the tag's
size. Members can change tag categories for tags with up to 50 posts,
and Builders can change categories for tags with up to 1000 posts.
Manually locking tags is not necessary.
We only had a few dozen locked tags, mostly random *_(cosplay) tags or
company name tags. Most of these are holdovers from moderators randomly
locking tags like ten years ago.
The `is_locked` field is still in the database, so it is still returned
by the /tags.json API, even though it is unused.
The problem was that we were stripping color profiles from thumbnails,
but we weren't setting `export_profile: "srgb"` to convert images to
sRGB first. This resulted in wrong colors for images with non-sRGB color
profiles, such as Adobe RGB.
The fix is to convert images to sRGB when possible, while leaving CMYK
and greyscale images alone. We leave CMYK images alone because we can't
convert CMYK to sRGB without losing color. We leave greyscale images
alone if they don't have a color profile, that way they stay as
one-channel greyscale (or two-channel greyscale, in case of alpha)
instead of being converted to three-channel sRGB. However, if a
greyscale image has a color profile, then we have to convert to sRGB,
otherwise the colors would be wrong when we strip the profile.
We also have to set the import profile, otherwise images with broken
embedded color profiles won't have a fallback profile and may get
incorrect colors. In this case we also have to be careful, because we
can't specify an sRGB fallback for greyscale or CMYK images.
Make the `order:random` metatag truly randomize the search. Add a
`random:N` metatag that returns up to N random posts, like what
`order:random` did before.
`order:random` now returns the entire search in random order. Before it
just returned a pageful of pseudorandom posts. This will be more
accurate for small searches, but slower for large searches. If
`order:random` times out, try `random:N` instead.
The `random:N` metatag returns up to N pseudorandom posts. This is
faster than `order:random` for large searches, but for small searches,
it may return less than N posts, and the randomness may be biased. Some
posts may be more likely than others to appear. N must be between 0 and
200.
Also, `/posts?tags=touhou&random=1` now redirects to `/posts?tags=touhou+random:N`.
Before the `random=1` param acted like a free `order:random` tag; now it
redirects to a `random:N` search, so it counts against your tag limit.
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.
* Add a gap between thumbnails on mobile.
* Adjust CSS for scores and vote buttons.
* Include "Private favorites" as an incentive on the user upgrade page.
* Fix vote buttons not being visible beneath thumbnails on mobile.
* Fix the "Show scores" link not preserving the current page number.
* Fix vote buttons being unintentionally enabled for all thumbnails by default.
* Fix banned and restricted users being able to favorite posts by
tagging them with `fav:self`.
* Fix search engines being able to crawl /posts?view=score pages.
* Fix broken tests.
Make upvotes public the same way favorites are public:
* Rename the "Private favorites" account setting to "Private favorites and upvotes".
* Make upvotes public, unless the user has private upvotes enabled. Note
that private upvotes are still visible to admins. Downvotes are still
hidden to everyone except for admins.
* Make https://danbooru.donmai.us/post_votes visible to all users. This
page shows all public upvotes. Private upvotes and downvotes are only
visible on the page to admins and to the voter themselves.
* Make votes searchable with the `upvote:username` and `downvote:username`
metatags. These already existed before, but they were only usable by
admins and by people searching for their own votes.
Upvotes are public to discourage users from upvoting with multiple
accounts. Upvote abuse is obvious to everyone when upvotes are public.
The other reason is to make upvotes consistent with favorites, which are
already public.
Add `upvotes:N`, `downvotes:N`, `order:upvotes`, `order:downvotes`,
`order:upvotes_asc`, `order:downvotes_asc` metatags.
In the API, the field is called up_score / down_score. Here it's called
`upvotes` and `downvotes` because this should be easier to understand
for end users.
Note that internally, `down_score` is negative. A post that matches
`downvotes:>5` will have down_score < -5 internally.
Fix certain artist commentaries for foundation.app containing scrambled
characters. Apparently caused by the Nokogiri HTML5 parser not handling
UTF-8 input correctly when the encoding isn't explicitly set to UTF-8.
Change the rules for automatically retiring aliases and implications:
* Retire aliases to tags that are empty, or that are for a general or
artist tag that hasn't received any new posts in the last two years.
* Retire implications from tags that are empty.
* Don't retire aliases or implications for character, copyright, or
meta tags any more, unless the tags are empty.
Make it possible to reapprove failed BURs that removed aliases or
implications.
Before if a BUR failed midway through, and we tried to reapprove it,
then it would fail when it got to a `remove alias` line because the
alias had already been removed. Now we keep going if we try to remove an
alias or implication that has already been removed.
* Change `age:` metatag to require time units. This means e.g.
`age:<600` no longer works; instead you have to say `age:<600sec`.
* Allow time units in the `age:` metatag to be abbreviated as long as
they're unambiguous. This means `age:<60sec`, `age:<5min`, and
`age:<5mon` now work, in addition to `age:<60s` and `age:<60seconds`.
* Allow the `ratio:` metatag to be written like `ratio:16/9` in addition
to `ratio:16:9`.
* Fix invalid date searches like `date:foo` or `date:05-15-2021`
to return nothing instead of raising an "undefined method
'beginning_of_day' for nil" exception. (`date:05-15-2021` is invalid
because it's parsed as DD-MM-YYYY).
* Fix invalid searches like `score:foo`, `ratio:foo`, and `mpixels:foo`
to return nothing instead of being treated like `score:0`, `ratio:0`,
`mpixels:0`.
* Fix `age:<60m` to return nothing instead of silently being treated
like `age:<60seconds`.
* Fix `age:foo` to return nothing instead of silently being treated like
`age:0d` (return all uploads from today).
Fixes#4389.
Refactor StorageManager to remove all image URL generation code. Instead
the image URL generation code lives in MediaAsset.
Now StorageManager is only concerned with how to read and write files to
remote storage backends like S3 or SFTP, not with how image URLs should
be generated. This way the file storage code isn't tightly coupled to
posts, so it can be used to store any kind of file, not just images
belonging to posts.
Fix it so that when a post is expunged, the media asset is also marked
as expunged. This way the files will be deleted, but the media asset
will still remain as a record of what was expunged. The media asset will
have the md5, width, height, file ext, and file size of the deleted file.
