refactor(vacuum statuses): reduce amount of db queries and load for each query - improve performance (#21487)
* refactor(statuses_vacuum): remove dead code - unused

Method is not called inside class and private.
Clean up dead code.

* refactor(statuses_vacuum): make retention_period present test explicit

This private method only hides functionality.
It is best practice to be as explicit as possible.

* refactor(statuses_vacuum): improve query performance

- fix statuses_scope having sub-select for Account.remote scope by
  `joins(:account).merge(Account.remote)`
- fix statuses_scope unnecessary use of `Status.arel_table[:id].lt`
  because it is inexplicit, bad practice and even slower than normal
  `.where('statuses.id < ?'`
- fix statuses_scope remove select(:id, :visibility) for having reusable
  active record query batches (no re queries)
- fix vacuum_statuses! to use in_batches instead of find_in_batches,
  because in_batches delivers a full blown active record query result,
  in stead of an array - no requeries necessary
- send(:unlink_from_conversations) not to perform another db query, but
  reuse the in_batches result instead.
- remove now obsolete remove_from_account_conversations method
- remove_from_search_index uses array of ids, instead of mapping
  the ids from an array - this should be more efficient
- use the in_batches scope to call delete_all, instead of running
  another db query for this - because it is again more efficient
- add TODO comment for calling models private method with send

* refactor(status): simplify unlink_from_conversations

- add `has_many through:` relation mentioned_accounts
- use model scope local instead of method call `Status#local?`
- more readable add account to inbox_owners when account.local?

* refactor(status): searchable_by way less sub selects

These queries all included a sub-select. Doing the same with a joins
should be more efficient.
Since this method does 5 such queries, this should be significant,
since it technically halves the query count.

This is how it was:

```ruby
[3] pry(main)> Status.first.mentions.where(account: Account.local, silent: false).explain
  Status Load (1.6ms)  SELECT "statuses".* FROM "statuses" WHERE "statuses"."deleted_at" IS NULL ORDER BY "statuses"."id" DESC LIMIT $1  [["LIMIT", 1]]
  Mention Load (1.5ms)  SELECT "mentions".* FROM "mentions" WHERE "mentions"."status_id" = $1 AND "mentions"."account_id" IN (SELECT "accounts"."id" FROM "accounts" WHERE "accounts"."domain" IS NULL) AND "mentions"."silent" = $2  [["status_id", 109382923142288414], ["silent", false]]
=> EXPLAIN for: SELECT "mentions".* FROM "mentions" WHERE "mentions"."status_id" = $1 AND "mentions"."account_id" IN (SELECT "accounts"."id" FROM "accounts" WHERE "accounts"."domain" IS NULL) AND "mentions"."silent" = $2 [["status_id", 109382923142288414], ["silent", false]]
                                                    QUERY PLAN
------------------------------------------------------------------------------------------------------------------
 Nested Loop  (cost=0.15..23.08 rows=1 width=41)
   ->  Seq Scan on accounts  (cost=0.00..10.90 rows=1 width=8)
         Filter: (domain IS NULL)
   ->  Index Scan using index_mentions_on_account_id_and_status_id on mentions  (cost=0.15..8.17 rows=1 width=41)
         Index Cond: ((account_id = accounts.id) AND (status_id = '109382923142288414'::bigint))
         Filter: (NOT silent)
(6 rows)
```

This is how it is with this change:

```ruby
[4] pry(main)> Status.first.mentions.joins(:account).merge(Account.local).active.explain
  Status Load (1.7ms)  SELECT "statuses".* FROM "statuses" WHERE "statuses"."deleted_at" IS NULL ORDER BY "statuses"."id" DESC LIMIT $1  [["LIMIT", 1]]
  Mention Load (0.7ms)  SELECT "mentions".* FROM "mentions" INNER JOIN "accounts" ON "accounts"."id" = "mentions"."account_id" WHERE "mentions"."status_id" = $1 AND "accounts"."domain" IS NULL AND "mentions"."silent" = $2  [["status_id", 109382923142288414], ["silent", false]]
=> EXPLAIN for: SELECT "mentions".* FROM "mentions" INNER JOIN "accounts" ON "accounts"."id" = "mentions"."account_id" WHERE "mentions"."status_id" = $1 AND "accounts"."domain" IS NULL AND "mentions"."silent" = $2 [["status_id", 109382923142288414], ["silent", false]]
                                                    QUERY PLAN
------------------------------------------------------------------------------------------------------------------
 Nested Loop  (cost=0.15..23.08 rows=1 width=41)
   ->  Seq Scan on accounts  (cost=0.00..10.90 rows=1 width=8)
         Filter: (domain IS NULL)
   ->  Index Scan using index_mentions_on_account_id_and_status_id on mentions  (cost=0.15..8.17 rows=1 width=41)

Mastodon

GitHub release Build Status Code Climate Crowdin Docker Pulls

Mastodon is a free, open-source social network server based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub)!

Features

No vendor lock-in: Fully interoperable with any conforming platform

It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! Learn more

Real-time, chronological timeline updates

Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!

Media attachments like images and short videos

Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos loop continuously!

Safety and moderation tools

Mastodon includes private posts, locked accounts, phrase filtering, muting, blocking and all sorts of other features, along with a reporting and moderation system. Learn more

OAuth2 and a straightforward REST API

Mastodon acts as an OAuth2 provider, so 3rd party apps can use the REST and Streaming APIs. This results in a rich app ecosystem with a lot of choices!

Deployment

Tech stack:

  • Ruby on Rails powers the REST API and other web pages
  • React.js and Redux are used for the dynamic parts of the interface
  • Node.js powers the streaming API

Requirements:

  • PostgreSQL 9.5+
  • Redis 4+
  • Ruby 2.6+
  • Node.js 14+

The repository includes deployment configurations for Docker and docker-compose as well as specific platforms like Heroku, Scalingo, and Nanobox. The standalone installation guide is available in the documentation.

A Vagrant configuration is included for development purposes. To use it, complete following steps:

  • Install Vagrant and Virtualbox
  • Install the vagrant-hostsupdater plugin: vagrant plugin install vagrant-hostsupdater
  • Run vagrant up
  • Run vagrant ssh -c "cd /vagrant && foreman start"
  • Open http://mastodon.local in your browser

Contributing

Mastodon is free, open-source software licensed under AGPLv3.
