2021-03-24Update Mastodon to Rails 6.1 (#15910)Claire
* Update devise-two-factor to unreleased fork for Rails 6 support Update tests to match new `rotp` version. * Update nsa gem to unreleased fork for Rails 6 support * Update rails to 6.1.3 and rails-i18n to 6.0 * Update to unreleased fork of pluck_each for Ruby 6 support * Run "rails app:update" * Add missing ActiveStorage config file * Use config.ssl_options instead of removed ApplicationController#force_ssl Disabled force_ssl-related tests as they do not seem to be easily testable anymore. * Fix nonce directives by removing Rails 5 specific monkey-patching * 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

2020-12-26Fix being able to import more than allowed number of follows (#15384)ThibG
* Fix being able to import more than allowed number of follows Without this commit, if someone tries importing a second list of accounts to follow before the first one has been processed, this will queue imports for the two whole lists, even if they exceed the account's allowed number of 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). * Catch validation errors to not re-queue failed follows Co-authored-by: Claire <claire.github-309c@sitedethib.com>

2020-12-23Fix mentions not being deleted efficiently (#15416)ThibG
As a regression from the recent optimizations, mentions were left untouched until `account.destroy`, which would then delete them individually, and executing queries to find and delete associated notifications, resulting in a massive slowdown.

2020-12-18Fix follow limit preventing re-following of a moved account (#14207)Eugen Rochko
2020-12-17Improve searching for private toots from URL (#14856)ThibG
* 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 Co-authored-by: Claire <claire.github-309c@sitedethib.com>

2020-11-27Fix deletes not reaching every server that interacted with status (#15200)Eugen Rochko
Extract logic for determining ActivityPub inboxes to send deletes to to its own class and explicitly include the person the status replied to (even if not mentioned), people who favourited it, and people who replied to it (though that one is still not recursive)
2020-11-21Undo outgoing follows when suspending a remote account (#15188)ThibG
2020-11-19Fix webfinger redirect handling in ResolveAccountService (#15187)ThibG
* Fix webfinger redirect handling in ResolveAccountService ResolveAccountService#process_webfinger! handled a one-step webfinger redirection, but only accepting the result if it matched the exact URI passed as input, defeating the point of a redirection check. Instead, use the same logic as in `ActivityPub::FetchRemoteAccountService`, updating the resulting `acct:` URI with the result of the first webfinger query. * Add tests
2020-11-19Add import/export feature for bookmarks (#14956)ThibG
* Add ability to export bookmarks * Add support for importing bookmarks * Add bookmark import tests * Add bookmarks export test
2020-11-19Fix sending spurious Rejects when processing remote account deletion (#15104)ThibG
* Fix sending spurious Rejects when processing remote account deletion * Make skip_side_effects imply skip_activitypub
2020-11-19Add cache buster feature for media files (#15155)Eugen Rochko
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.

2020-10-23Fix followers synchronization mechanism not being triggered on mentions (#15026)ThibG
e.g. if someone on an instance that previously had followers gets mentioned in a private toot, before this PR, they would not receive a Collection-Synchronization header and may show the toot to the former followers in addition to the mentioned person.
2020-10-23Fix account processing failing because of large collections (#15027)ThibG
Fixes #15025
2020-10-21Add follower synchronization mechanism (#14510)ThibG
* 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

2020-10-12Add IP-based rules (#14963)Eugen Rochko
2020-10-08Remove dependency on goldfinger gem (#14919)Eugen Rochko
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
2020-09-18Add option to be notified when a followed user posts (#13546)Eugen Rochko
* 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
