3.4.1 dropped account_stats.lock_version, but in a way breaking the usual
upgrade path by requiring services to be reloaded after the post-migrations.
Indeed, `self.locking_column = nil` was not enough for Rails to ignore the
`lock_version` column when preparing statements on application load, resulting
in some ActiveRecord queries (typically those involving
`includes(:account_stat)`) erroring out with:
ActiveRecord::StatementInvalid (PG::UndefinedColumn: ERROR: column account_stats.lock_version does not exist
* Fix account deletion sometimes failing because of optimistic locks
In some rare occasions[1], deleting accounts would fail with a
`StaleObjectError` exception.
Indeed, account deletion manually sets the `AccountStat` values without
handling cases where the optimistic locking on `AccountStat` would fail.
To my knowledge, with the rewrite of account counters in #15913, the
`DeleteAccountService` is now the only place that changes the counters in
a way that is not atomic.
Since in this specific case, we do not care about the previous values of the
account counters, it appears we don't need locking at all for this table
anymore.

* Bump MAX_SUPPORTED_VERSION in maintenance script
Since #16173, `account_summaries` and `follow_recommendations` are not
populated at creation time, which causes concurrent refresh to fail.
As we currently only use those materialized views right after explicitly
refreshing them, this commit changes refreshes to not be performed
concurrently. This will fix the issue and ensure the refresh completes
faster while using less resources.
If a status with a hashtag becomes very popular, it stands to
reason that the hashtag should have a chance at trending
Fix no stats being recorded for hashtags that are not allowed

This will yield better performances when deleting an account
* Disable Rails 6.1's automatic preload link headers
Since Rails 6.1, ActionView adds preload links for javascript files
in the Links header per default.
In our case, that will bloat headers too much and potentially cause
issues with reverse proxies. Furhermore, we don't need those links,
as we already output them as HTML link tags.
* Switch to Rails 6.0 default config
* Switch to Rails 6.1 default config
* Do not include autoload paths in the load path
* Improve account counters handling
* Use ActiveRecord::Base::sanitize_sql to pass values instead of interpolating them
Keep using string interpolation for `key` as it is safe and using
“ActiveRecord::Base::sanitize_sql_hash_for_assignment” would require stitching
bits of SQL in a way that is not more easily checked for safety.
* Add migration hook to catch PostgreSQL versions earlier than 9.5
* Fix misuse of foreign_type
* Fix use of removed "add_template_helper"
* Use response.media_type instead of response.content_type in tests
* Fix CSV export controller test on Rails 6
Rails 6 sets a "filename*" field in the Content-Disposition header to
explicitly encode the filename as UTF-8.
This changes checks the first part of the Content-Disposition header so
it matches in both Rails 5 and Rails 6.
* Fix emoji formatting with Rails 6
* Make emoji output more idiomatic and robust
* Switch from redis-rails gem to built-in Rails redis cache storage
An uncommon but somewhat difficult to digagnose issue is dealing with
improperly-seeded databases. In such cases, instance-signed fetches will
fail with a ActiveRecord::RecordNotFound error, usually caught and handled
as generic 404, leading people to think the remote resource itself has not
been found, while it's the local instance actor that does not exist.
This commit changes the code so that failure to find the instance actor
automatically creates a new one, so that improperly-seeded databases do
not cause any issue.

Without this commit, if someone tries importing a second list of accounts to

outgoing follows.
This commit changes it so the individual queued imports aren't exempt from
the follow limit check (they remain exempt from the rate-limiting check
though).

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
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
* Add support for followers synchronization on the receiving end
Check the `collectionSynchronization` attribute on `Create` and `Announce`
activities and synchronize followers from provided collection if possible.
* Add tests for followers synchronization on the receiving end
* Add support for follower synchronization on the sender's end
* Add tests for the sending end
* Switch from AS attributes to HTTP header
Replace the custom `collectionSynchronization` ActivityStreams attribute by
an HTTP header (`X-AS-Collection-Synchronization`) with the same syntax as
the `Signature` header and the following fields:
- `collectionId` to specify which collection to synchronize
- `digest` for the SHA256 hex-digest of the list of followers known on the
receiving instance (where “receiving instance” is determined by accounts
sharing the same host name for their ActivityPub actor `id`)
- `url` of a collection that should be fetched by the instance actor
Internally, move away from the webfinger-based `domain` attribute and use
account `uri` prefix to group accounts.
* Add environment variable to disable followers synchronization
Since the whole mechanism relies on some new preconditions that, in some
extremely rare cases, might not be met, add an environment variable
(DISABLE_FOLLOWERS_SYNCHRONIZATION) to disable the mechanism altogether and
avoid followers being incorrectly removed.
The current conditions are:
1. all managed accounts' actor `id` and inbox URL have the same URI scheme and
netloc.
2. all accounts whose actor `id` or inbox URL share the same URI scheme and
netloc as a managed account must be managed by the same Mastodon instance
as well.
As far as Mastodon is concerned, breaking those preconditions require extensive
configuration changes in the reverse proxy and might also cause other issues.
Therefore, this environment variable provides a way out for people with highly
unusual configurations, and can be safely ignored for the overwhelming majority
of Mastodon administrators.
* Only set follower synchronization header on non-public statuses
This is to avoid unnecessary computations and allow Follow-related
activities to be handled by the usual codepath instead of going through
the synchronization mechanism (otherwise, any Follow/Undo/Accept activity
would trigger the synchronization mechanism even if processing the activity
itself would be enough to re-introduce synchronization)
* Change how ActivityPub::SynchronizeFollowersService handles follow requests
If the remote lists a local follower which we only know has sent a follow
request, consider the follow request as accepted instead of sending an Undo.
* Integrate review feeback
- rename X-AS-Collection-Synchronization to Collection-Synchronization
- various minor refactoring and code style changes
* Only select required fields when computing followers_hash
* Use actor URI rather than webfinger domain in synchronization endpoint
* Change hash computation to be a XOR of individual hashes
Makes it much easier to be memory-efficient, and avoid sorting discrepancy issues.
* Marginally improve followers_hash computation speed
* Further improve hash computation performances by using pluck_each
There are edge cases where requests to certain hosts timeout when
using the vanilla HTTP.rb gem, which the goldfinger gem uses. Now
that we no longer need to support OStatus servers, webfinger logic
is so simple that there is no point encapsulating it in a gem, so
we can just use our own Request class. With that, we benefit from
more robust timeout code and IPv4/IPv6 resolution.

* Make Array-creation behavior of Paginable more predictable
Paginable.paginate_by_id usually returns ActiveRecord::Relation, but it
returns an Array if min_id option is present. The behavior caused problems
fixed with the following commits:
- 552e886b64
- b63ede5005
- 64ef37b89d
To prevent from recurring similar problems, this commit introduces two
changes:
- The scope now always returns an Array whether min_id option is present
or not.
- The scope is renamed to to_a_paginated_by_id to clarify it returns an
Array.
* Transform Paginable.to_a_paginated_by_id from a scope to a class method
https://api.rubyonrails.org/classes/ActiveRecord/Scoping/Named/ClassMethods.html#method-i-scope
> The method is intended to return an ActiveRecord::Relation object, which
> is composable with other scopes.
Paginable.to_a_paginated_by_id returns an Array and is not appropriate
as a scope.
* feat: add possibility of adding WebAuthn security keys to use as 2FA
This adds a basic UI for enabling WebAuthn 2FA. We did a little refactor
to the Settings page for editing the 2FA methods – now it will list the
methods that are available to the user (TOTP and WebAuthn) and from
there they'll be able to add or remove any of them.
Also, it's worth mentioning that for enabling WebAuthn it's required to
have TOTP enabled, so the first time that you go to the 2FA Settings
page, you'll be asked to set it up.
This work was inspired by the one donde by Github in their platform, and
despite it could be approached in different ways, we decided to go with
this one given that we feel that this gives a great UX.

* feat: add request for WebAuthn as second factor at login if enabled
This commits adds the feature for using WebAuthn as a second factor for
login when enabled.
If users have WebAuthn enabled, now a page requesting for the use of a
WebAuthn credential for log in will appear, although a link redirecting
to the old page for logging in using a two-factor code will also be
present.

Co-authored-by: Facundo Padula <facundo.padula@cedarcode.com>
* feat: remove ability to disable TOTP leaving only WebAuthn as 2FA
Following examples form other platforms like Github, we decided to make
Webauthn 2FA secondary to 2FA with TOTP, so that we removed the
possibility of removing TOTP authentication only, leaving users with
just WEbAuthn as 2FA. Instead, users will have to click on 'Disable 2FA'
in order to remove second factor auth.
The reason for WebAuthn being secondary to TOPT is that in that way,
users will still be able to log in using their code from their phone's
application if they don't have their security keys with them – or maybe
even lost them.
* We had to change a little the flow for setting up TOTP, given that now
it's possible to setting up again if you already had TOTP, in order to
let users modify their authenticator app – given that now it's not
possible for them to disable TOTP and set it up again with another
authenticator app.
So, basically, now instead of storing the new `otp_secret` in the
user, we store it in the session until the process of set up is
finished.
This was because, as it was before, when users clicked on 'Edit' in
the new two-factor methods lists page, but then went back without
finishing the flow, their `otp_secret` had been changed therefore
invalidating their previous authenticator app, making them unable to
log in again using TOTP.

When an admins disable 2FA for users, we were sending two mails

that WebAuthn was disabled.
As the second one is redundant since the first email includes it, we can
remove it and send just one email to users.

Since #14145, the `set_type_and_extension` has been moved from
`before_post_process` to `before_file_post_process`, but while the former
runs before all validations performed by Paperclip, the latter is dependent
on the order validations and hooks are defined.
In our case, this meant video files could be checked against the generic 10MB
limit, causing validation failures, which, internally, make Paperclip skip
post-processing, and thus, transcoding of the video file.
The actual validation would then happen after the type is correctly set, so
the large file would pass validation, but without being transcoded first.
This commit moves the hook definition so that it is run before checking for
the file size.

When deduplicating account usernames for OAuthable users, the routine did check if any account was known with that username, including remote accounts. This caused some unnecessary deduplication, and usernames ending with unexpected trailing _1.
This fixes#13580
Follow-up to #13452, fixing broken `uri.nil?` test.
Also remove the separate check for `uri` presence, as that would result
in a “Please review 2 errors below” while only one would be listed.
* Fix “Email changed” notification sometimes having wrong e-mail
Fixes#6778
The root of the issue is that `send_devise_notification` was called before
the changes were properly commited to the database, causing the mailer to
pick previous values if running too early.
Devise's documentation provides guidance on how to handle that[1][2], however,
I have found it to not be working, as the following happens, in that order:
- `send_devise_notification` is called for the `email_changed` notification.
In that case, `changed?` is false and `saved_changes?` is true, so
if we use the former, we have the same issue.
- the `after_commit` hook is called
- `send_devise_notification` is called for the `confirmation_instructions`
notification.
In that case, `changed?` is still false, and `saved_changes?` still true,
so if we use the latter, that second notification email is simply not
going to be sent (as we would be queuing the notification *after*
executing the after_commit hook).
This is because it may be called from either an `after_update` or
`after_commit` hook, the difference not being a call to `save` but the
transaction actually being committed to the database. This may arguably
be a bug in Devise, or Devise's notification.
The proposed workaround is inspired by Devise's documentation but checks
whether a transaction is open to make the call whether to immediately
send the notification or defer it to the `after_commit` hook.

Fixes#13245 by caching status lookups
Since statuses are supposed to be known already and we only
need their URLs and a few other things, caching them should
be fine.
Since it's only used by announcements so far, there won't
be much statuses to cache.
* Perform status lookup when saving announcements, not when rendering them
* Change EntityCache#status to fetch URLs instead of looking into the database
* Move announcement link lookup to publishing worker
* Address issues pointed out during review
* Change ActivityPub follower/following collections to not link first page
* Add support for hiding followers and following of remote users
* Switch to using a single `hide_collections` column
* Address code style remarks
Change `all_day` to be a visual client-side cue only
Publish immediately if `scheduled_at` is in the past
Add `published_at` and `updated_at` to announcements JSON
While making browser requests in the other sessions after a password
change or reset does not allow you to be logged in and correctly
invalidates the session making the request, sessions have API tokens
associated with them, which can still be used until that session
is invalidated.
This is a security issue for accounts that were already compromised
some other way because it makes it harder to throw out the hijacker.

* Delete display_name method
* Add follow_request notification type
The notification type already existed in the backend but was never pushed
to the front-end. This also means translation strings were also available
for the backend, from the notification mailer.
Unlike other notification types, these are off by default, to match what
I remember of Gargron's view on the topic: that follow requests should not
clutter notifications and should instead be reviewed at the user's own
leisure in the dedicated column.
Since follow requests have their own column, I've deemed it unnecessary to
add a specific tab for them in the notification quick filter.
* Show follow request link in single-column if there are pending requests, even if account isn't locked
* Push follow requests from notifications to the follow_requests list
* Offer to accept or reject follow request from the notification

Before this patch, if remote poll options have leading or trailing spaces,
the information stored locally won't match them, causing federated voting to
fail.

Change the behaviour of remotable concern. Previously, it would skip
downloading an attachment if the stored remote URL is identical to
