fee7ed506b comments: put sticky option in popup menu instead of in edit form.
Put the option to sticky a comment in the "..." popup menu instead of
in the comment edit form. This makes it more consistent with deleting or
undeleting a comment.

Also fix a bug where the comment undelete icon didn't show up due to a
typo.

58e42ee8d3 rate limits: add /rate_limits endpoint.
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

413cd34c45 rate limits: adjust limits for various actions.
* Tie rate limits to both the user's ID and their IP address.

* Make each endpoint have separate rate limits. This means that, for
  example, your post edit rate limit is separate from your post vote
  rate limit. Before all write actions had a shared rate limit.

* Make all write endpoints have rate limits. Before some endpoints, such
  as voting, favoriting, commenting, or forum posting, weren't subject
  to rate limits.

* Add stricter rate limits for some endpoints:

** 1 per 5 minutes for creating new accounts.
** 1 per minute for login attempts, changing your email address, or
   for creating mod reports.
** 1 per minute for sending dmails, creating comments, creating forum
   posts, or creating forum topics.
** 1 per second for voting, favoriting, or disapproving posts.
** These rate limits all have burst factors high enough that they
   shouldn't affect normal, non-automated users.

* Raise the default write rate limit for Gold users from 2 per second to
  4 per second, for all other actions not listed above.

* Raise the default burst factor to 200 for all other actions not listed
  above. Before it was 10 for Members, 30 for Gold, and 60 for Platinum.

4492610dfe rate limits: rework rate limit implementation.
Rework the rate limit implementation to make it more flexible:

* Allow setting different rate limits for different actions. Before we
  had a single rate limit for all write actions. Now different
  controller endpoints can have different limits.

* Allow actions to be rate limited by user ID, by IP address, or both.
  Before actions were only limited by user ID, which meant non-logged-in
  actions like creating new accounts or attempting to login couldn't be rate
  limited. Also, because actions were limited by user ID only, you could
  use multiple accounts with the same IP to get around limits.

Other changes:

* Remove the API Limit field from user profile pages.
* Remove the `remaining_api_limit` field from the `/profile.json` endpoint.
* Rename the `X-Api-Limit` header to `X-Rate-Limit` and change it from a
  number to a JSON object containing all the rate limit info
  (including the refill rate, the burst factor, the cost of the call,
  and the current limits).
* Fix a potential race condition where, if you flooded requests fast
  enough, you could exceed the rate limit. This was because we checked
  and updated the rate limit in two separate steps, which was racy;
  simultaneous requests could pass the check before the update happened.
  The new code uses some tricky SQL to check and update multiple limits
  in a single statement.

1c1d784547 css: rework color scheme to use new color palette.
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.

3d01febcf7 api keys: require reauthentication when working with API keys.
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.

25fda1ecc2 api keys: add IP whitelist and API permission system.
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.

d0c9f6e0b8 posts: allow toggling between upvotes and downvotes.
Like 9efb374ae, allow users to toggle between upvoting and downvoting a
post without raising an error or having to manually remove the vote
first. If you upvote a post, then downvote it, the upvote is
automatically removed and replaced by the downvote.

Other changes:

* Tagging a post with `upvote:self` or `downvote:self` is now silently
  ignored when the user doesn't have permission to vote, instead of
  raising an error.
* Undoing a vote that doesn't exist now does nothing instead of
  returning an error. This can happen if you open the same post in two
  tabs, undo the vote in tab 1, then try to undo the vote again in tab 2.

Changes to the /post_votes API:

* `POST /post_votes` and `DELETE /post_votes` now return a post vote
  instead of a post.
* The `score` param in `POST /post_votes` is now 1 or -1, not `up` or
  `down`.

07bdc6eab0 comments: rework thresholded comments.
Previously thresholded comments were hidden completely. You had to click
the "Show X hidden comments" button to unhide all hidden comments in a
thread. Now it works like this:

* When a comment is below your threshold, the comment text is hidden and
  replaced by a `[hidden]` link, which you can click to unhide the comment.

* When a comment is at half your threshold (for example, your threshold
  is -8 but the comment is at -4), then the comment is greyed out.

This means that comments aren't completely hidden, they're just
collapsed, so you can see the commenter and the score without unhiding
the comment. It also means you don't have to scroll back up to unhide a
comment, and threads aren't disrupted by comments being secretly
hidden (which is confusing when people are replying to hidden comments,
which forces you to go back up and unhide to find).

054ac51d47 policies: remove current request from context.
This refactors Pundit policies to only rely on the current user, not on
the current user and the current HTTP request. In retrospect, it was a
bad idea to include the current request in the Pundit context. It bleeds
out everywhere and there are many contexts (in tests and models) where
we only have the current user, not the current request. The previous
commit got rid of the only two places where we used it.

Refactor email verification links and Dmail share links to use the new

For Dmail share links, we have to override some Rails internal methods

will invalidate existing links, but this isn't a huge deal since these
links are short-lived anyway.

65adcd09c2 users: track logins, signups, and other user events.
Add tracking of certain important user actions. These events include:

* Logins
* Logouts
* Failed login attempts
* Account creations
* Account deletions
* Password reset requests
* Password changes
* Email address changes

This is similar to the mod actions log, except for account activity
related to a single user.

The information tracked includes the user, the event type (login,
logout, etc), the timestamp, the user's IP address, IP geolocation
information, the user's browser user agent, and the user's session ID
from their session cookie. This information is visible to mods only.

This is done with three models. The UserEvent model tracks the event
type (login, logout, password change, etc) and the user. The UserEvent
is tied to a UserSession, which contains the user's IP address and
browser metadata. Finally, the IpGeolocation model contains the
geolocation information for IPs, including the city, country, ISP, and
whether the IP is a proxy.

This tracking will be used for a few purposes:

* Letting users view their account history, to detect things like logins
  from unrecognized IPs, failed logins attempts, password changes, etc.
* Rate limiting failed login attempts.
* Detecting sockpuppet accounts using their login history.
* Detecting unauthorized account sharing.

94e125709c users: add Restricted user level.
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.

b6f9c9a866 post regenerations: regenerate posts asynchronously.
Regenerate posts asynchronously using a delayed job.

Regenerating a post can be slow because it involves downloading the
original file, regenerating the thumbnails, and redistributing the new
thumbnails back to the image servers. It's better to run this in the
background, especially if a user is trying to regenerate posts in bulk.

The downside is there's no notification to the user when the regeneration
is complete. You have to check the modactions log to see when it's finished.

df44937c57 post regenerations: replace PostRegeneration model with mod actions.
* Remove the PostRegeneration model. Instead just use a mod action
  to log when a post is regenerated.

* Change it so that IQDB is also updated when the image samples are
  regenerated. This is necessary because when the images samples are
  regenerated, the thumbnail may change, which means IQDB needs to be
  updated too. This can happen when regenerating old images with
  transparent backgrounds where the transparency was flattened to black
  instead of white in the thumbnail.

* Only display one "Regenerate image" option in the post sidebar, to
  regenerate both the images and IQDB. Regenerating IQDB only can be
  done through the API. Having two options in the sidebar is too much
  clutter, and it's too confusing for Mods who don't know the difference
  between an IQDB-only regeneration and a full image regeneration.

* Add a confirm prompt to the "Regenerate image" link.

d0bb4ed398 user upgrades: add bank payment methods for European countries.
Add the following bank redirect payment methods:

* https://stripe.com/docs/payments/eps

* https://stripe.com/docs/payments/ideal
* https://stripe.com/docs/payments/p24

These methods are used in Austria, Belgium, Germany, the Netherlands,
and Poland.

These methods require payments to be denominated in EUR, which means we
have to set prices in both USD and EUR, and we have to automatically
detect which currency to use based on the user's country. We also have
to automatically detect which payment methods to offer based on the
user's country. We do this by using Cloudflare's CF-IPCountry header to
geolocate the user's country.

This also switches to using prices and products defined in Stripe
instead of generated on-the-fly when creating the checkout.

* Store the upgrade status:
** pending: User is still on the Stripe checkout page, no payment

** processing: User has completed checkout, but the checkout status in
   Stripe is still 'unpaid'.
** complete: We've received notification from Stripe that the payment
   has gone through and the user has been upgraded.
* Store the Stripe checkout ID, to cross-reference the upgrade record on

This is the upgrade flow:

* When the user clicks the upgrade button on the upgrade page, we call
  POST /user_upgrades and create a pending UserUpgrade.
* We redirect the user to the checkout page on Stripe.
* When the user completes checkout on Stripe, Stripe sends us a webhook
  notification at POST /webhooks/receive.
* When we receive the webhook, we check the payment status, and if it's
  paid we mark the UserUpgrade as complete and upgrade the user.
* After Stripe sees that we have successfully processed the webhook,
  they redirect the user to the /user_upgrades/:id page, where we show
  the user their upgrade receipt.

from seeing backtraces in failed controller tests).
