2020-12-18Fix follow limit preventing re-following of a moved account (#14207)Eugen Rochko
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

2018-05-04Store URIs of follows, follow requests and blocks for ActivityPub (#7160)Eugen Rochko
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.

2017-11-28Allow hiding of reblogs from followed users (#5762)aschmitz
* Allow hiding of reblogs from followed users This adds a new entry to the account menu to allow users to hide future reblogs from a user (and then if they've done that, to show future reblogs instead). This does not remove or add historical reblogs from/to the user's timeline; it only affects new statuses. The API for this operates by sending a "reblogs" key to the follow endpoint. If this is sent when starting a new follow, it will be respected from the beginning of the follow relationship (even if the follow request must be approved by the followee). If this is sent when a follow relationship already exists, it will simply update the existing follow relationship. As with the notification muting, this will now return an object ({reblogs: [true|false]}) or false for each follow relationship when requesting relationship information for an account. This should cause few issues due to an object being truthy in many languages, but some modifications may need to be made in pickier languages. Database changes: adds a show_reblogs column (default true, non-nullable) to the follows and follow_requests tables. Because these are non-nullable, we use the existing MigrationHelpers to perform this change without locking those tables, although the tables are likely to be small anyway. Tests included. See also <https://github.com/glitch-soc/mastodon/pull/212>. * Rubocop fixes * Code review changes * Test fixes This patchset closes #648 and resolves #3271. * Rubocop fix * Revert reblogs defaulting in argument, fix tests It turns out we needed this for the same reason we needed it in muting: if nil gets passed in somehow (most usually by an API client not passing any value), we need to detect and handle it. We could specify a default in the parameter and then also catch nil, but there's no great reason to duplicate the default value.

* Add structure for lists * Add list timeline streaming API * Add list APIs, bind list-account relation to follow relation * Add API for adding/removing accounts from lists * Add pagination to lists API * Add pagination to list accounts API * Adjust scopes for new APIs - Creating and modifying lists merely requires "write" scope - Fetching information about lists merely requires "read" scope * Add test for wrong user context on list timeline * Clean up tests
2017-11-12Update model annotations to use BIGINT for IDs (#5461)Daniel Hunsaker
All the migrations have been updated to use BIGINTs for ID fields in the DB, but ActiveRecord needs to be told to treat those values as BIGINT as well. This PR does that.
2017-10-02Make IdsToBigints (mostly!) non-blocking (#5088)aschmitz
* Make IdsToBigints (mostly!) non-blocking This pulls in GitLab's MigrationHelpers, which include code to make column changes in ways that Postgres can do without locking. In general, this involves creating a new column, adding an index and any foreign keys as appropriate, adding a trigger to keep it populated alongside the old column, and then progressively copying data over to the new column, before removing the old column and replacing it with the new one. A few changes to GitLab's MigrationHelpers were necessary: * Some changes were made to remove dependencies on other GitLab code. * We explicitly wait for index creation before forging ahead on column replacements. * We use different temporary column names, to avoid running into index name length limits. * We rename the generated indices back to what they "should" be after replacing columns. * We rename the generated foreign keys to use the new column names when we had to create them. (This allows the migration to be rolled back without incident.) # Big Scary Warning There are two things here that may trip up large instances: 1. The change for tables' "id" columns is not concurrent. In particular, the stream_entries table may be big, and does not concurrently migrate its id column. (On the other hand, x_id type columns are all concurrent.) 2. This migration will take a long time to run, *but it should not lock tables during that time* (with the exception of the "id" columns as described above). That means this should probably be run in `screen` or some other session that can be run for a long time. Notably, the migration will take *longer* than it would without these changes, but the website will still be responsive during that time. These changes were tested on a relatively large statuses table (256k entries), and the service remained responsive during the migration. Migrations both forward and backward were tested. * Rubocop fixes * MigrationHelpers: Support ID columns in some cases This doesn't work in cases where the ID column is referred to as a foreign key by another table. * MigrationHelpers: support foreign keys for ID cols Note that this does not yet support foreign keys on non-primary-key columns, but Mastodon also doesn't yet have any that we've needed to migrate. This means we can perform fully "concurrent" migrations to change ID column types, and the IdsToBigints migration can happen with effectively no downtime. (A few operations require a transaction, such as renaming columns or deleting them, but these transactions should not block for noticeable amounts of time.) The algorithm for generating foreign key names has changed with this, and therefore all of those changed in schema.rb. * Provide status, allow for interruptions The MigrationHelpers now allow restarting the rename of a column if it was interrupted, by removing the old "new column" and re-starting the process. Along with this, they now provide status updates on the changes which are happening, as well as indications about when the changes can be safely interrupted (when there are at least 10 seconds estimated to be left before copying data is complete). The IdsToBigints migration now also sorts the columns it migrates by size, starting with the largest tables. This should provide administrators a worst-case scenario estimate for the length of migrations: each successive change will get faster, giving admins a chance to abort early on if they need to run the migration later. The idea is that this does not force them to try to time interruptions between smaller migrations. * Fix column sorting in IdsToBigints Not a significant change, but it impacts the order of columns in the database and db/schema.rb. * Actually pause before IdsToBigints
