On the post index page, show the wiki excerpt if the search includes a
single tag, even if the tag is negated or the search includes other
metatags.
If the search includes a single pool: or ordpool: metatag, show the pool
excerpt even if the search includes other metatags.
Several fixes for the "This tag is under discussion" notice on the post
index page:
* Fix the notice appearing for BURs that aren't pending.
* Fix the notice never going away because of the cache never expiring.
* List all topics when a tag is involved in multiple BURs.
* Link to the forum post instead of the forum topic (fix#4421).
* Optimization: don't check for BURs when the search isn't a simple
single tag search.
* Add a `tags` field to the bulk update requests table for tracking all
tags involved in the request (excluding tags in mass updates that are
negated/optional/wildcards). Known issue: doesn't handle tag type
prefixes in mass updates correctly (e.g. `mass update foo -> artist:bar`
doesn't detect the tag `bar`).
* Allow searching the /bulk_update_requests page by tags.
We don't really need to cache the notice here, but we do it anyway to
reduce queries on the post index page.
* Make IP bans soft deletable.
* Add a hit counter to track how many times an IP ban has blocked someone.
* Add a last hit timestamp to track when the IP ban last blocked someone.
* Add a new type of IP ban, the signup ban. Signup bans restrict new
signups from editing anything until they've verified their email
address.
Use validations instead of raising an exception when the password is
incorrect so that the controller can display errors sensibly.
Also fix users being logged out even when the deletion attempt failed
due to an incorrect password.
* Allow tagging a post with a `disapproved:<disinterest|breaks_rules|poor_quality>` to disapprove it.
* Disallow disapproving active posts.
Fixes#4384.
When random mode is enabled @post_set.posts returns an array, which
caused `authorize` to try to lookup the wrong policy.
This only happens when `authorize` is given an array with more than one
element, which is why it wasn't caught by the tests.
Remove the ability to authenticate to the API with the `login` and
`password_hash` url parameters. This is a legacy authentication method
from Danbooru 1. How to actually generate the password_hash for this
method hasn't been fully documented for many years now. It required
taking the SHA1 hash of your password combined with an undocumented salt
value (i.e., password_hash = sha1("choujin-steiner--#{password}")).
This authentication method was also slow because it required checking
the password on every API call. Checking passwords is deliberately slow
because passwords are hashed with BCrypt. BCrypt takes about ~200ms per
request, so using this method effectively limited you to ~5 requests per
second in a single thread.
* Make authentication methods into User instance methods instead of
class methods.
* Fix API key authentication to use a secure string comparison. Fixes a
hypothetical (unlikely to be exploitable) timing attack.
* Move login logic from SessionCreator to SessionLoader.
Require users who signup using proxies to verify their email addresses
before they can perform any edits. For verification purposes, the email
must be a nondisposable address from a whitelist of trusted email
providers.
Pull the password reauthentication logic out of the user model and put
it in the password update controller where it belongs.
This fixes an issue where when a new user was created the user model had
an incorrect password error set on it by `encrypt_password_on_update`.
It was trying to verify the old password even though we don't have one
when creating a new user. This error caused the user create action to
redirect back to the signup page because `respond_with` thought that
creating the user failed.
Reject email addresses that known to be undeliverable during signup.
Some users signup with invalid email addresses, which causes the welcome
email (which contains the email confirmation link) to bounce. Too many
bounces hurt our ability to send mail.
We check that an email address is undeliverable by checking if the
domain has a mail server and if the server returns an invalid address
error when attempting to send mail. This isn't foolproof since some
servers don't return an error if the address doesn't exist. If the
checks fail we know the address is bad, but if the checks pass that
doesn't guarantee the address is good. However, this is still good
enough to filter out bad addresses for popular providers like Gmail and
Microsoft that do return nonexistent address errors.
The address existence check requires being able to connect to mail
servers over port 25. This may fail if your network blocks port 25,
which many home ISPs and hosting providers do by default.
* Move old post archive tests to post version tests.
* Fix pool tests that assumed that multiple edits by the same user
weren't merged.
* Fix references to `is_active` and `notes` on artist model.
* Fix the pool version SQS service to always be mocked before every
test. Before we had to manually set it up before every test dealing
with pool versions.
* Fix it so that we reconnect to the post/pool version databases before
every test. Before using $ARCHIVE_DATABASE_URL to set the database url
failed because environment variables weren't loaded by dotenv yet when
connections were first established.
Side effects:
* The data-current-user-is-voter <body> attribute has been removed.
* {{upvote:self}} no longer works. {{upvote:<name>}} should be used instead.
