Nginx can be configured to bypass proxy cache when a special header
is in the request. If the response is cacheable, it will replace
the cache for that request. Proxy caching of media files is
desirable when using object storage as a way of minimizing bandwidth
costs, but has the drawback of leaving deleted media files for
a configured amount of cache time. A cache buster can make those
media files immediately unavailable. This especially makes sense
when suspending and unsuspending an account.
* 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
* Add bell button
Fix#4890
* Remove duplicate type from post-deployment migration
* Fix legacy class type mappings
* Improve query performance with better index
* Fix validation
* Remove redundant index from notifications
* Change move handler to carry blocks and mutes over
When user A blocks user B and B moves to a new account C, make A block C
accordingly.
Note that it only works if A's instance is aware of the Move, that is,
if B is on A's instance or has followers there.
* Also notify instances with known people blocking you when moving
* Add automatic account notes when blocking/muting an account that had no note
* Add UserNote model
* Add UI for user notes
* Put comment in relationships entity
* Add API to create user notes
* Copy user notes to new account when receiving a Move activity
* Address some of the review remarks
* Replace modal by inline edition
* Please CodeClimate
* Button design changes
* Change design again
* Cancel note edition when pressing Escape
* Fixes
* Tweak design again
* Move “Add note” item, and allow users to add notes to themselves
* Rename UserNote into AccountNote, rename “comment” Relationship attribute to “note”
- Change audio files to not be stripped of metadata
- Automatically extract cover art from audio if it exists
- Add `thumbnail` parameter to `POST /api/v1/media`, `POST /api/v2/media` and `PUT /api/v1/media/:id`
- Add `icon` to represent it in attachments in ActivityPub
- Fix `preview_url` containing URL of missing missing image when there is no thumbnail instead of null
- Fix duration of audio not being displayed on public pages until the file is loaded
- Fix audio attachments not being represented in OpenGraph tags
- Fix audio being represented as "1 image" in OpenGraph descriptions
- Fix video metadata being overwritten by paperclip-av-transcoder
- Fix embedded player not using Mastodon's UI
- Fix audio/video progress bars not moving smoothly
- Fix audio/video buffered bars not displaying correctly
* Split media cleanup from reject-media domain blocks to its own service
* Slightly improve ClearDomainMediaService error handling
* Lower DomainClearMediaWorker to lowest-priority queue
* Do not catch ActiveRecord::RecordNotFound in domain block workers
* Fix DomainBlockWorker spec labels
* Add some specs
* Change domain blocks to immediately mark accounts as suspended
Rather than doing so sequentially, account after account, while cleaning
their data. This doesn't change much about the time the block takes to
complete, but it immediately prevents interaction with the blocked domain,
while up to now, it would only be guaranteed when the process ends.
* Fix PostgreSQL load when linking in announcements
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
Also:
- Fix locks not being removed when jobs go to the dead job queue
- Add UI for managing locks to the Sidekiq dashboard
- Remove unused Sidekiq workers
Fix#13349
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
* Add announcements
Fix#11006
* Add reactions to announcements
* Add admin UI for announcements
* Add unit tests
* Fix issues
- Add `with_dismissed` param to announcements API
- Fix end date not being formatted when time range is given
- Fix announcement delete causing reactions to send streaming updates
- Fix announcements container growing too wide and mascot too small
- Fix `all_day` being settable when no time range is given
- Change text "Update" to "Announcement"
* Fix scheduler unpublishing announcements before they are due
* Fix filter params not being passed to announcements filter
* Fix being able to follow oneself by moving to an account that was following the old one

* Fix migration from remote to local account not sending Undo Follow
* Fix show_reblogs not being preserved for moved account's followers
