* 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
* Fix the local group's followers collection
* Fix to accept followed relayed_through_account
* Add local delivery to the group's followers
* Fix code style
* Revert "Add local delivery to the group's followers"
This reverts commit 3237effc19.
* Show badge on group actor in WebUI
* Do not notify in case of by following group actor
* If you mention group actor, also mention group actor followers
* Relax characters that can be used in username (same as Application)
* Revert "Relax characters that can be used in username (same as Application)"
This reverts commit 7e10a137b8.
* Delete display_name method
* Add support for an instance actor
* Skip username validation for local Application accounts
* Add migration script to create instance actor
* Make Codeclimate happy
* Switch to id -99 for instance actor
* Remove unused `icon` and `image` attributes from instance actor
* Use if/elsif/else instead of return + ternary operator
* Add instance actor to fresh installs
* Use instance actor as instance representative
Use instance actor for forwarding reports, relay operations, and spam
auto-reporting.
* Seed database in test environment
* Fix single-user mode
* Fix tests
* Fix specs to accomodate for an extra `Account`
* Auto-reject follows on instance actor
Following an instance actor might make sense, but we are not handling that
right now, so auto-reject.
* Fix webfinger lookup and serialization for instance actor
* Rename instance actor
* Make it clear in the HTML view that the instance actor should not be blocked
* Raise cache time for instance actor as there's no dynamic content
* Re-use /about/more with a flash message for instance actor profile
* Prevent silenced local users from notifying remote users not following them
This is an attempt to extend the local restrictions of silenced users to the
federation.
* Add tests
* Add tests for making sure private status don't get sent over OStatus
* Add silent column to mentions
* Save silent mentions in ActivityPub Create handler and optimize it
Move networking calls out of the database transaction
* Add "limited" visibility level masked as "private" in the API
Unlike DMs, limited statuses are pushed into home feeds. The access
control rules between direct and limited statuses is almost the same,
except for counter and conversation logic
* Ensure silent column is non-null, add spec
* Ensure filters don't check silent mentions for blocks/mutes
As those are "this person is also allowed to see" rather than "this
person is involved", therefore does not warrant filtering
* Clean up code
* Use Status#active_mentions to limit returned mentions
* Fix code style issues
* Use Status#active_mentions in Notification
And remove stream_entry eager-loading from Notification
Same URI passed between follow request and follow, since they are
the same thing in ActivityPub. Local URIs are generated during
creation using UUIDs and are passed to serializers.
This makes slightly more sense, and ensures that the author of a post is always referenced in the audience (which some servers might rely on). And the announce is POSTed to the author's inbox anyways.
We had returned `nil` for that case, but this raises an error instead, as a wrong usage of the method.
This method is currently only used in ActivitySerializer.
In before, the method uses stream_entry id as status id, so replied status was wrongly selected.
This PR uses StatusFinder which was introduced with `Api::Web::EmbedsController`.
* Process Create / Announce activity in FetchRemoteStatusService
* Use activity URL in ActivityPub for reblogs
* Redirect to the original status on StatusesController#show
- Tries to avoid performing HTTP request if the keyId is an actor URI
- Likewise if the URI is a fragment URI on top of actor URI
- Resolves public key, returns owner if the owner links back to the key
* Add ActivityPub inbox
* Handle ActivityPub deletes
* Handle ActivityPub creates
* Handle ActivityPub announces
* Stubs for handling all activities that need to be handled
* Add ActivityPub actor resolving
* Handle conversation URI passing in ActivityPub
* Handle content language in ActivityPub
* Send accept header when fetching actor, handle JSON parse errors
* Test for ActivityPub::FetchRemoteAccountService
* Handle public key and icon/image when embedded/as array/as resolvable URI
* Implement ActivityPub::FetchRemoteStatusService
* Add stubs for more interactions
* Undo activities implemented
* Handle out of order activities
* Hook up ActivityPub to ResolveRemoteAccountService, handle
Update Account activities
* Add fragment IDs to all transient activity serializers
* Add tests and fixes
* Add stubs for missing tests
* Add more tests
* Add more tests
* Improve webfinger templates and make tests more flexible
* Clean up AS2 representation of actor
* Refactor outbox
* Create activities representation
* Add representations of followers/following collections, do not redirect /users/:username route if format is empty
* Remove unused translations
* ActivityPub endpoint for single statuses, add ActivityPub::TagManager for better
URL/URI generation
* Add ActivityPub::TagManager#to
* Represent all attachments as Document instead of Image/Video specifically
(Because for remote ones we may not know for sure)
Add mentions and hashtags representation to AP notes
* Add AP-resolvable hashtag URIs
* Use ActiveModelSerializers for ActivityPub
* Clean up unused translations
* Separate route for object and activity
* Adjust cc/to matrices
* Add to/cc to activities, ensure announce activity embeds target status and
not the wrapper status, add "id" to all collections
