The `pry` gem was removed in e698bf91 because we replaced `pry-byebug` with the standard debugger.
Add it back because `pry` is better than `irb` and we still can use the standard debugger with it.
* Call it "Changes" when referring to the global list of changes (pool changes, artist changes, etc).
* Call it "History" when referring to the history of a single item (pool history, artist history, etc).
* Put the artist history search form on the /artist_versions page, and remove the /artist_versions/search endpoint.
Fix external HTTP requests not working when the HTTP proxy was enabled. Caused by the `public_only`
option (which prevents SSRF attacks by validating that the URL doesn't resolve to a local IP) being
incompatible with the `proxy` option.
Don't log a mod action when a user deletes their own account. This isn't a moderator action, so it
doesn't belong here. Account deletions are still logged on the /user_events page (visible to mods only).
A mod action is still logged when the Owner-level user deletes someone else's account.
Add media_asset_id and old_media_asset_id columns for associating replacements with media assets.
This way we can easily tell which replacements don't have a media asset (with the md5 alone we can't
tell whether the media asset actually exists).
Add a fix script to download images from Gelbooru for old replacements where we deleted the original
image. For archival purposes, we want to try to find the original file for every replacement.
These images will be uploaded as unposted assets under DanbooruBot's name.
Add a fix script that imports the md5 for old post replacements from the corresponding DanbooruBot
replacement comment, then deletes all replacement comments.
There are about 250 replacements left that still have a null md5 because they don't have a matching
comment. This is because if a post was replaced but the file didn't change, it didn't leave a comment.
Fix `Relation passed to #and must be structurally compatible. Incompatible values: [:joins] (ArgumentError)`
exception in `ordfav:evazion ratio:4:3` search. Broken by e849d8f1c.
We were effectively doing this:
q1 = Post.joins(:favorites, :media_asset).where("favorites.user_id = ?", 52664).order("favorites.id DESC")
q2 = Post.joins(:media_asset, :favorites).where("ROUND(media_assets.image_width::numeric / media_assets.image_height::numeric, 2) = 1.33")
q3 = q1.and(q2)
This failed because Rails didn't like the fact that the joins were in a different order when the
queries were `and`-ed together.
Don't allow users to choose names that conflict with search syntax, like `any` or `none`, or names
that impersonate user levels, like `Admin`, `Moderator`, `Anonymous`, etc.
Fix three exploits that allowed one to keep using their account after it was deleted:
* It was possible to use session cookies from another computer to login after you deleted your account.
* It was possible to use API keys to make API requests after you deleted your account.
* It was possible to request a password reset, delete your account, then use the password reset link
to change your password and login to your deleted account.
* Don't delete the user's favorites unless private favorites are enabled. The general rule is that
public account activity is kept and private account activity is deleted.
* Delete the user's API keys, forum topics visits, private favgroups, downvotes, and upvotes (if
privacy is enabled).
* Reset all of the user's account settings to default. This means custom CSS is deleted, where it
wasn't before.
* Delete everything but the user's name and password asynchronously.
* Don't log the current user out if it's the owner deleting another user's account.
* Fix#5067 (Mod actions sometimes not created for user deletions) by wrapping the deletion process
in a transaction.
Move the account deletion endpoint from /maintenance/users/deletion to either:
* https://danbooru.donmai.us/users/deactivate
* https://danbooru.donmai.us/users/:id/deactivate
This incidentally allows the Owner-level user to deactivate accounts belonging to other users. This
is meant for things like deactivating inactive accounts with invalid or abusive names. This is
limited to accounts below Gold level for security.
