Fix discrepancy between index action and show action. The index
action allowed members to see name changes for undeleted users, but the
show action didn't.
Also remove non-nullable and default options from migration. The column
didn't originally have these options so they shouldn't be added if the
migration is reverted.
Previously only actions that were marked member_only or above were
subject to IP ban restrictions. This meant that certain actions that
weren't marked member_only, like creating new accounts, could still be
done by IP banned users.
Now IP banned users can't do any non-GET actions, which means they're
not allowed to even login to their accounts.
* Move emails from users table to email_addresses table.
* Validate that addresses are formatted correctly and are unique across
users. Existing invalid emails are grandfathered in.
* Add is_verified flag (the address has been confirmed by the user).
* Add is_deliverable flag (an undeliverable address is an address that bounces).
* Normalize addresses to prevent registering multiple accounts with the
same email address (using tricks like Gmail's plus addressing).
Remove code for updating forum topics when an alias or implication is
approved or rejected. This code was only used when approving single
alias or implication requests. This is no longer used now that all
alias/implication requests are done through BURs.
The old password reset flow:
* User requests a password reset.
* Danbooru generates a password reset nonce.
* Danbooru emails user a password reset confirmation link.
* User follows link to password reset confirmation page.
* The link contains a nonce authenticating the user.
* User confirms password reset.
* Danbooru resets user's password to a random string.
* Danbooru emails user their new password in plaintext.
The new password reset flow:
* User requests a password reset.
* Danbooru emails user a password reset link.
* User follows link to password edit page.
* The link contains a signed_user_id param authenticating the user.
* User changes their own password.
* Fix users being redirected back to the change password page after
successfully changing their password.
* Move passwords controller out of /maintenance/ namespace.
* Add tests.
* Support negated wildcards in searches (e.g. "holding -holding_*")
* Raise wildcard limit to matching 25 tags regardless of user level.
* Fix wildcards potentially matching empty tags.
* Fix wildcard tags being sorted by post count only, and therefore not
having a stable ordering when tags have equal post counts.
* Fix sidebar to calculate wildcards tags the same way the search does.
Rename is_active to is_deleted. This is for better consistency with
other models, and to reduce confusion over what "active" means for
artists. Sometimes users think active is for whether the artist is
actively producing work.
This meant that both functions had to return two separate values,
which need to be destructured by the function calling them. This
isn't so much a huge issue as its more something just to be made
aware of in case either function needs to be used elsewhere.
