* Add trending links
* Add overriding specific links trendability
* Add link type to preview cards and only trend articles
Change trends review notifications from being sent every 5 minutes to being sent every 2 hours
Change threshold from 5 unique accounts to 15 unique accounts
* Fix tests
* Fix error when suspending user with an already-existing canonical email block
Fixes#17033
While attempting to create a `CanonicalEmailBlock` with an existing hash would
raise an `ActiveRecord::RecordNotUnique` error, this being done within a
transaction would cancel the whole transaction. For this reason, checking for
uniqueness in Rails would query the database within the transaction and avoid
invalidating the whole transaction for this reason.
A race condition is still possible, where multiple accounts sharing a canonical
email would be blocked in concurrent transactions, in which only one would
succeed, but that is way less likely to happen that the current issue, and can
always be retried after the first failure, unlike the current situation.
* Add tests
* Add tests
* Fix some link previews being incorrectly generated from different prior links
PR #12403 added a cache to avoid redundant queries when the OEmbed endpoint can
be guessed from the URL. This caching mechanism is not perfectly correct as
there is no guarantee that all pages from a given domain share the same
OEmbed provider endpoint.
This PR prevents the FetchOEmbedService from caching OEmbed endpoint that
cannot be generalized by replacing a fully-qualified URL from the endpoint's
parameters, greatly reducing the number of incorrect cached generalizations.
* Add support for fetching Create and Announce activities by URI
This should improve compatibility with ZAP and offer a way to fetch boosts,
which is currently not possible.
* Add tests
* Add followed_by? to account_interactions
* Add RemoveFromFollowersService
* Fix AccountBatch to use RemoveFromFollowersService
* Add remove from followers API

* Fix media attachment size validation not correctly accounting for file type
Fixes a regression introduced in #16724 caused by the fact that kt-paperclip
now correctly runs validations before processing, meaning that file size
verification could not rely on our before_post_processing hook.
Moved the `before_post_processing` hooks to `before_validate` to make sure
the media attachment type is set correctly before the file gets validated.
* Add tests
Conflicts:

* 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.
Conflicts:
- `streaming/index.js`:
Filtering code for streaming notifications has been refactored upstream, but
glitch-soc had similar code for local-only toots in the same places.
Ported upstream changes, but did not refactor local-only filtering.
* Stop setting a shortcode to newly-created media attachments
The WebUI has stopped using the “short media URL” in ages. This isn't used
anywhere except for mail notifications.
Deprecating it would allow us to eventually get rid of at least a database
column and corruption-prone index, as well as a controller.
* Fix tests
* Add tests
* Add security-related tests
My first (unpublished) attempt at fixing the issues introduced (extremely
hard-to-exploit) security vulnerabilities, addressing them in a test.
* Fix authentication failures after going halfway through a sign-in attempt
* Refactor `authenticate_with_sign_in_token` and `authenticate_with_two_factor` to make the two authentication steps more obvious
* 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
Conflicts:

* Add service to cleanup a given account's statuses within a budget
* Add worker to go through account policies and delete old toots
* Fix last inspected status id logic
All existing statuses older or equal to last inspected status id must be
kept by the current policy. This is an invariant that must be kept so that
resuming deletion from the last inspected status remains sound.
* Add tests

* Fix anonymous access to outbox not being cached by the reverse proxy
Up until now, anonymous access to outbox was marked as public, but with a
0 duration for caching, which means remote proxies would only serve from cache
when the server was completely overwhelmed.
Changed that cache duration to one minute, so that repeated anonymous access
to one account's outbox can be appropriately cached.
Also added `Signature` to the `Vary` header in case a page is requested, so
that authenticated fetches are never served from cache (which only contains
public toots).
* Remove Vary: Accept header from webfinger controller
Indeed, we have stopped returning xrd, and only ever return jrd, so the
Accept request header does not matter anymore.
* Cache negative webfinger hits for 3 minutes
* Add tests
* Fix serialization of followers/following counts when user hides their network

* Fix fixture_file_upload deprecation warning
* Fix yield-based test failing with Rails 6
* Use Rails 6's index_with when possible
* Use ActiveRecord::Cache::Store#delete_multi from Rails 6
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
* Bypass MX validation for explicitly allowed domains
This spares some lookups and prevent issues in some edge cases with
local domains.
* Add tests
* Fix test
* 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
* Use ActiveRecord::Result#to_ary instead of deprecated to_hash
They do the same thing, and to_hash has been removed from Rails 6.1
* Explicitly name polymorphic indexes to workaround a bug in Rails 6.1
cf. https://github.com/rails/rails/issues/41693
* Fix incorrect usage of “foreign_key” in migration script
* Use `ActiveModel::Errors#delete` instead of deprecated clear method
* Fix link headers tests on Rails 6.1
Rails 6.1 adds values to the Link header by default, thus it is not a
LinkHeader object anymore. Fix the test to parse the Link header instead
of assuming it is a LinkHeader.
* Prepare Mastodon for zeitwerk autoloader (Rails 6)
Add inflections and rename/move a few classes.
In particular, app/lib/exceptions.rb and app/lib/sanitize_config.rb
were manually loaded while still in autoload paths.
* Add inflection for Url → URL
* 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 URI of repeat follow requests not being recorded
In case we receive a “repeat” or “duplicate” follow request, we automatically
fast-forward the accept with the latest received Activity `id`, but we don't
record it.
In general, a “repeat” or “duplicate” follow request may happen if for some
reason (e.g. inconsistent handling of Block or Undo Accept activities, an
instance being brought back up from the dead, etc.) the local instance thought
the remote actor were following them while the remote actor thought otherwise.
In those cases, the remote instance does not know about the older Follow
activity `id`, so keeping that record serves no purpose, but knowing the most
recent one is useful if the remote implementation at some point refers to it
by `id` without inlining it.
* Add tests
* Added .deepsource.toml
* Removed bad use of `alias`
* Fixed operand order in the binary expression
* Prefixed unused method arguments with an underscore

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).

* Improve searching for private toots from URL
Most of the time, when sharing toots, people use the toot URL rather than
the toot URI, which makes sense since it is the user-facing URL.
In Mastodon's case, the URL and URI are different, and Mastodon does not
have an index on URL, which means searching a private toot by URL is done
with a slow query that will only succeed for very recent toots.
This change gets rid of the slow query, and attempts to guess the URI from
URL instead, as Mastodon's are predictable.
* Add tests
* Only return status with guessed uri if url matches

Add two honeypot fields: a fake website input and a fake password confirmation

query.

* 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.
Fix#14091
