Fixes#13136
When a user's canonical acct domain is different from its id's domain
(WEB_DOMAIN ≠ LOCAL_DOMAIN), two webfinger queries are required to find the
canonical domain from the URI. However, we skip webfinger queries when
updating only the key of a remote user, which led to the creation of a
duplicate account, using the URI's domain instead of the canonical acct: one.
* Change domain blocks to automatically support subdomains
If a more authoritative domain is blocked (example.com), then the
same block will be applied to a subdomain (foo.example.com)
* Match subdomains of existing accounts when blocking/unblocking domains
* Improve code style
* Record account suspend/silence time and keep track of domain blocks
* Also unblock users who were suspended/silenced before dates were recorded
* Add tests
* Keep track of suspending date for users suspended through the CLI
* Show accurate number of accounts that would be affected by unsuspending an instance
* Change migration to set silenced_at and suspended_at
* Revert "Also unblock users who were suspended/silenced before dates were recorded"
This reverts commit a015c65d2d.
* Switch from using suspended and silenced to suspended_at and silenced_at
* Add post-deployment migration script to remove `suspended` and `silenced` columns
* Use Account#silence! and Account#suspend! instead of updating the underlying property
* Add silenced_at and suspended_at migration to post-migration
* Change account fabricator to translate suspended and silenced attributes
* Minor fixes
* Make unblocking domains always retroactive
* Add Tombstone model to remember object deletion
* Do not recreate a status if it has been deleted
* Record Tombstone for remote deleted items
Also, only record deleted items from same-host actors
* Clear an user's tombstones when their key change
* Refactor signature verification a bit
* Rescue signature verification if recorded public key is invalid
Fixes#8822
* Always re-fetch AP signing key when HTTP Signature verification fails
But when the account is not marked as stale, avoid fetching collections and
media, and avoid webfinger round-trip.
* Apply stoplight to key/account update as well as initial key retrieval
* Verify link ownership with rel="me"
* Add explanation about verification to UI
* Perform link verifications
* Add click-to-copy widget for verification HTML
* Redesign edit profile page
* Redesign forms
* Improve responsive design of settings pages
* Restore landing page sign-up form
* Fix typo
* Support <link> tags, add spec
* Fix links not being verified on first discovery and passive updates
* If an Update is signed with known key, skip re-following procedure
Because it means the remote actor did *not* lose their database
* Add CLI method for rotating keys
bin/tootctl accounts rotate [USERNAME]
Generates a new RSA key per account and sends out an Update activity
signed with the old key.
* Key rotation: Space out Update fan-outs every 5 minutes per 1000 accounts
* Skip suspended accounts in key rotation
Updates account `uri` field on each call to `update_account` instead of
only once during `create_account` to mirror the same behavior in OStatus
`ResolveAccountService` class [0].
ActivityPub accounts are identified using `@username` and `@domain` pair
instead of URI since #6842.
This fixes#7479: a bug when the account identified by `@username` and
`@domain` changes its URI.

* Add equals_or_includes_any? helper in JsonLdHelper
* Support arrays in JSON-LD type fields for actors/tags/objects.
* Spec for resolving accounts with extension types
* Style tweaks for codeclimate
* Add bio fields
- Fix#3211
- Fix#232
- Fix#121
* Display bio fields in web UI
* Fix output of links and missing fields
* Federate bio fields over ActivityPub as PropertyValue

Fix#121
* Fix actors accepting invalid URI schemes or different host between URI and URL
* Fix statuses accepting invalid URI scheme or different host to actor
* Adjust tests to new requirements
* Improve readability of mismatching_origin?/invalid_origin? methods
* Add semi-support for Video/Image objects in ActivityPub
Video and Image objects will create corresponding status records
with manually crafted text contents (title + URL)
* Extract html-url-finding logic into JsonLdHelper
* Fallback to id when url missing, extract supported object types
* Serialize moved accounts into REST and ActivityPub APIs
* Parse federated moved accounts from ActivityPub
* Add note about moved accounts to public profiles
* Add moved account message to web UI
* Fix code style issues
Additionally, ActivityPub::FetchRemoteStatusService no longer parses
activities.
OStatus::Activity::Creation no longer delegates to ActivityPub because
the provided ActivityPub representations are not signed while OStatus
representations are.
* Whenever a remote keypair changes, unfollow them and re-subscribe to them
In Mastodon (it could be different for other OStatus or AP-enabled software),
a keypair change is indicative of whole user (or instance) data loss. In this
situation, the “new” user might be different, and almost certainly has an empty
followers list. In this case, Mastodon instances will disagree on follower
lists, leading to unreliable delivery and “shadow followers”, that is users
believed by a remote instance to be followers, without the affected user
knowing.
Drawbacks of this change are:
1. If an user legitimately changes public key for some reason without losing
data (not possible in Mastodon at the moment), they will have their remote
followers unsubscribed/re-subscribed needlessly.
2. Depending of the number of remote followers, this may generate quite some
traffic.
3. If the user change is an attempt at usurpation, the remote followers will
unknowingly follow the usurper. Note that this is *not* a change of
behavior, Mastodon already behaves like that, although delivery might be
unreliable, and the usurper would not have known the former user's
followers.
* Rename ResubscribeWorker to RefollowWorker
* Process followers in batches
- Fix assumption that `url` is always a string. Handle it if it's an
array of strings, array of objects, object, or string, both for
accounts and for objects
- `sharedInbox` is actually supposed to be under `endpoints`, handle
both cases and adjust the serializer
Using _: property names is discouraged, as in the future,
canonicalization may throw an error when encountering that instead
of discarding it silently like it does now.
We are defining some ActivityStreams properties which we expect
to land in ActivityStreams eventually, to ensure that future versions
of Mastodon will remain compatible with this even once that happens.
Those would be `locked`, `sensitive` and `Hashtag`
We are defining a custom context inline for some properties which we
do not expect to land in any other context. `atomUri`, `inReplyToAtomUri`
and `conversation` are part of the custom defined OStatus context.
* Fallback to OStatus in FetchAtomService
* Skip activity+json link if that activity is Person without inbox
* If unsupported activity was detected and all other URLs failed, retry with ActivityPub-less Accept header
* Allow mention to OStatus account in ActivityPub
* Don't update profile with inbox-less Person object
* ActivityPub migration procedure
Once one account is detected as going from OStatus to ActivityPub,
invalidate WebFinger cache for other accounts from the same domain

* Re-subscribe to PuSH unless already unsubscribed, regardless of protocol
* Add ActivityPub inbox
