Conflicts:
- `app/models/account.rb`:
Not a real conflict, just upstream getting rid of unused constants too close
to glitch-soc-specific contents.
Removed unused constants like upstream did.
- `app/models/trends.rb`:
Conflict because glitch-soc disabled email notifications for trending links.
Upstream has refactored this quite a bit and added trending posts.
Took upstream code, but disabling the extra trending stuff will come in
another commit.
- `app/views/admin/trends/links/index.html.haml`:
Conflict due to glitch-soc's theming system.
Ported upstream changes accordingly.
* Add trending statuses
* Fix dangling items with stale scores in localized sets
* Various fixes and improvements
- Change approve_all/reject_all to approve_accounts/reject_accounts
- Change Trends::Query methods to not mutate the original query
- Change Trends::Query#skip to offset
- Change follow recommendations to be refreshed in a transaction
* Add tests for trending statuses filtering behaviour
* Fix not applying filtering scope in controller
Conflicts:
- `db/schema.rb`:
Conflict due to glitch-soc adding the `content_type` column on status edits
and thus having a different schema version number.
Solved by taking upstream's schema version number, as it is higher than
glitch-soc's.
* Add appeals
* Add ability to reject appeals and ability to browse pending appeals in admin UI
* Add strikes to account page in settings
* Various fixes and improvements
- Add separate notification setting for appeals, separate from reports
- Fix style of links in report/strike header
- Change approving an appeal to not restore statuses (due to federation complexities)
- Change style of successfully appealed strikes on account settings page
- Change account settings page to only show unappealed or recently appealed strikes
* Change appealed_at to overruled_at
* Fix missing method error
* Fix error-prone SQL queries in Account search
While this code seems to not present an actual vulnerability, one could
easily be introduced by mistake due to how the query is built.
This PR parameterises the `to_tsquery` input to make the query more robust.
* Harden code for Status#tagged_with_all and Status#tagged_with_none
Those two scopes aren't used in a way that could be vulnerable to an SQL
injection, but keeping them unchanged might be a hazard.
* Remove unneeded spaces surrounding tsquery term
* Please CodeClimate
* Move advanced_search_for SQL template to its own function
This avoids one level of indentation while making clearer that the SQL template
isn't build from all the dynamic parameters of advanced_search_for.
* Add tests covering tagged_with, tagged_with_all and tagged_with_none
* Rewrite tagged_with_none to avoid multiple joins and make it more robust
* Remove obsolete brakeman warnings
* Revert "Remove unneeded spaces surrounding tsquery term"
The two queries are not strictly equivalent.

* Switch from unmaintained paperclip to kt-paperclip
* Drop some compatibility monkey-patches not required by kt-paperclip
* Drop media spoof check monkey-patching
It's broken with kt-paperclip and hopefully it won't be needed anymore
* Fix regression introduced by paperclip 6.1.0
* Do not rely on pathname to call FastImage
* Add test for ogg vorbis file with cover art
* Add audio/vorbis to the accepted content-types
This seems erroneous as this would be the content-type for a vorbis stream
without an ogg container, but that's what the `marcel` gem outputs, so…
* Restore missing for_as_default method
* Refactor Attachmentable concern and delay Paperclip's content-type spoof check
Check for content-type spoofing *after* setting the extension ourselves, this
fixes a regression with kt-paperclip's validations being more strict than
paperclip 6.0.0 and rejecting some Pleroma uploads because of unknown
extensions.
* Please CodeClimate
* Add audio/vorbis to the unreliable set
It doesn't correspond to a file format and thus has no extension associated.
* Fix followers synchronization mechanism not working when URI has empty path
To my knowledge, there is no current implementation on the fediverse
that can use bare domains (e.g., actor is at https://example.org instead of
something like https://example.org/actor) that also plans to support the
followers synchronization mechanism. However, Mastodon's current implementation
would exclude such accounts from followers list.
Also adds tests and rename them to reflect the proper method names.
* Move url prefix regexp to its own constant
- `app/views/statuses/_simple_status.html.haml`:
Small markup change in glitch-soc, on a line that has been modified by

* 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
