Do not downcase the queried tag before passing it to postgres when searching:

  • tags are not downcased on creation
  • arel_table[:name].lower.matches(pattern) generates an ILIKE anyway
  • if Postgres and Rails happen to use different case-folding rules,
    downcasing before query but not before insertion may mean that some
    tags with some casings are not searchable

* Fix 2FA/sign-in token sessions being valid after password change (#14802)

If someone tries logging in to an account and is prompted for a 2FA
code or sign-in token, even if the account's password or e-mail is
updated in the meantime, the session will show the prompt and allow
the login process to complete with a valid 2FA code or sign-in token

* Fix Move handler not being triggered when failing to fetch target (#15107)

When failing to fetch the target account, the ProcessingWorker fails
as expected, but since it hasn't cleared the `move_in_progress` flag,
the next attempt at processing skips the `Move` activity altogether.

This commit changes it to clear the flag when encountering any
unexpected error on fetching the target account. This is likely to
occur because, of, e.g., a timeout, when many instances query the
same actor at the same time.

* Fix slow distinct queries where grouped queries are faster (#15287)

About 2x speed-up on inboxes query

* Fix possible inconsistencies in tag search (#14906)

* Fix updating account counters when account_stat is not yet created (#15108)

* Fix account processing failing because of large collections (#15027)

Fixes #15025

* Fix downloading remote media files when server returns empty filename (#14867)

Fixes #14817

* Fix webfinger redirect handling in ResolveAccountService (#15187)

* Fix webfinger redirect handling in ResolveAccountService

ResolveAccountService#process_webfinger! handled a one-step webfinger
redirection, but only accepting the result if it matched the exact URI passed
as input, defeating the point of a redirection check.

Instead, use the same logic as in `ActivityPub::FetchRemoteAccountService`,
updating the resulting `acct:` URI with the result of the first webfinger
query.

* Add tests

* Remove dependency on unused and unmaintained http_parser.rb gem (#14574)

It seems that years ago, the “http” gem dependend on the “http_parser.rb” gem
(it now depends on the “http-parser” gem), and, still years ago, we pulled
it from git in order to benefit from a bugfix that wasn't released yet (#7467).

* Add tootctl maintenance fix-duplicates (#14860, #15201, #15264, #15349, #15359)

* Fix old migration script not being able to run if it fails midway (#15361)

* Fix old migration script not being able to run if it fails midway

Improve the robustness of a migration script likely to fail because of database
corruption so it can run again once database corruptions are fixed.

* Display a specific error message in case of index corruption
