CHANGELOG.md

@@ -30,6 +30,8 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - AdminAPI: Add "godmode" while fetching user statuses (i.e. admin can see private statuses)
 - Improve digest email template
 – Pagination: (optional) return `total` alongside with `items` when paginating
+- Replaced [pleroma_job_queue](https://git.pleroma.social/pleroma/pleroma_job_queue) and `Pleroma.Web.Federator.RetryQueue` with [Oban](https://github.com/sorentwo/oban) (see [`docs/config.md`](docs/config.md) on migrating customized worker / retry settings)
+- Introduced [quantum](https://github.com/quantum-elixir/quantum-core) job scheduler
 
 ### Fixed

+# Configuration
+
+This file describe the configuration, it is recommended to edit the relevant *.secret.exs file instead of the others founds in the ``config`` directory.
+If you run Pleroma with ``MIX_ENV=prod`` the file is ``prod.secret.exs``, otherwise it is ``dev.secret.exs``.
+
+## Pleroma.Upload
+* `uploader`: Select which `Pleroma.Uploaders` to use
+* `filters`: List of `Pleroma.Upload.Filter` to use.
+* `link_name`: When enabled Pleroma will add a `name` parameter to the url of the upload, for example `https://instance.tld/media/corndog.png?name=corndog.png`. This is needed to provide the correct filename in Content-Disposition headers when using filters like `Pleroma.Upload.Filter.Dedupe`
+* `base_url`: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
+* `proxy_remote`: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
+* `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
+
+Note: `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.
+
+## Pleroma.Uploaders.Local
+* `uploads`: Which directory to store the user-uploads in, relative to pleroma’s working directory
+
+## Pleroma.Uploaders.S3
+* `bucket`: S3 bucket name
+* `bucket_namespace`: S3 bucket namespace
+* `public_endpoint`: S3 endpoint that the user finally accesses(ex. "https://s3.dualstack.ap-northeast-1.amazonaws.com")
+* `truncated_namespace`: If you use S3 compatible service such as Digital Ocean Spaces or CDN, set folder name or "" etc.
+For example, when using CDN to S3 virtual host format, set "".
+At this time, write CNAME to CDN in public_endpoint.
+
+## Pleroma.Upload.Filter.Mogrify
+
+* `args`: List of actions for the `mogrify` command like `"strip"` or `["strip", "auto-orient", {"implode", "1"}]`.
+
+## Pleroma.Upload.Filter.Dedupe
+
+No specific configuration.
+
+## Pleroma.Upload.Filter.AnonymizeFilename
+
+This filter replaces the filename (not the path) of an upload. For complete obfuscation, add
+`Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.
+
+* `text`: Text to replace filenames in links. If empty, `{random}.extension` will be used. You can get the original filename extension by using `{extension}`, for example `custom-file-name.{extension}`.
+
+## Pleroma.Emails.Mailer
+* `adapter`: one of the mail adapters listed in [Swoosh readme](https://github.com/swoosh/swoosh#adapters), or `Swoosh.Adapters.Local` for in-memory mailbox.
+* `api_key` / `password` and / or other adapter-specific settings, per the above documentation.
+* `enabled`: Allows enable/disable send  emails. Default: `false`.
+
+An example for Sendgrid adapter:
+
+```elixir
+config :pleroma, Pleroma.Emails.Mailer,
+  adapter: Swoosh.Adapters.Sendgrid,
+  api_key: "YOUR_API_KEY"
+```
+
+An example for SMTP adapter:
+
+```elixir
+config :pleroma, Pleroma.Emails.Mailer,
+  adapter: Swoosh.Adapters.SMTP,
+  relay: "smtp.gmail.com",
+  username: "YOUR_USERNAME@gmail.com",
+  password: "YOUR_SMTP_PASSWORD",
+  port: 465,
+  ssl: true,
+  tls: :always,
+  auth: :always
+```
+
+## :uri_schemes
+* `valid_schemes`: List of the scheme part that is considered valid to be an URL
+
+## :instance
+* `name`: The instance’s name
+* `email`: Email used to reach an Administrator/Moderator of the instance
+* `notify_email`: Email used for notifications.
+* `description`: The instance’s description, can be seen in nodeinfo and ``/api/v1/instance``

+* `account_activation_required`: Require users to confirm their emails before signing in.
+* `federating`: Enable federation with other instances
+* `federation_incoming_replies_max_depth`: Max. depth of reply-to activities fetching on incoming federation, to prevent out-of-memory situations while fetching very long threads. If set to `nil`, threads of any depth will be fetched. Lower this value if you experience out-of-memory crashes.
+* `federation_reachability_timeout_days`: Timeout (in days) of each external federation target being unreachable prior to pausing federating to it.
+* `allow_relay`: Enable Pleroma’s Relay, which makes it possible to follow a whole instance

+
+## :logger
+* `backends`: `:console` is used to send logs to stdout, `{ExSyslogger, :ex_syslogger}` to log to syslog, and `Quack.Logger` to log to Slack
+
+An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
+```elixir
+config :logger,
+  backends: [{ExSyslogger, :ex_syslogger}]
+
+config :logger, :ex_syslogger,
+  level: :warn
+```
+
+Another example, keeping console output and adding the pid to syslog output:
+```elixir
+config :logger,
+  backends: [:console, {ExSyslogger, :ex_syslogger}]
+
+config :logger, :ex_syslogger,
+  level: :warn,
+  option: [:pid, :ndelay]
+```
+
+See: [logger’s documentation](https://hexdocs.pm/logger/Logger.html) and [ex_syslogger’s documentation](https://hexdocs.pm/ex_syslogger/)
+
+An example of logging info to local syslog, but warn to a Slack channel:
+```elixir
+config :logger,
+  backends: [ {ExSyslogger, :ex_syslogger}, Quack.Logger ],
+  level: :info
+
+config :logger, :ex_syslogger,
+  level: :info,
+  ident: "pleroma",
+  format: "$metadata[$level] $message"
+
+config :quack,
+  level: :warn,
+  meta: [:all],
+  webhook_url: "https://hooks.slack.com/services/YOUR-API-KEY-HERE"

+
+## :frontend_configurations
+
+This can be used to configure a keyword list that keeps the configuration data for any kind of frontend. By default, settings for `pleroma_fe` and `masto_fe` are configured.
+
+Frontends can access these settings at `/api/pleroma/frontend_configurations`
+
+To add your own configuration for PleromaFE, use it like this:
+
+```elixir
+config :pleroma, :frontend_configurations,
+  pleroma_fe: %{
+    theme: "pleroma-dark",
+    # ... see /priv/static/static/config.json for the available keys.
+},
+  masto_fe: %{
+    showInstanceSpecificPanel: true
+  }
+```
+
+These settings **need to be complete**, they will override the defaults.
+
+NOTE: for versions < 1.0, you need to set [`:fe`](#fe) to false, as shown a few lines below.
+
+## :fe
+__THIS IS DEPRECATED__
+
+If you are using this method, please change it to the [`frontend_configurations`](#frontend_configurations) method.

+**Important note**: if you modify anything inside these lists, default `config.exs` values will be overwritten, which may result in breakage, to make sure this does not happen please copy the default value for the list from `config.exs` and modify/add only what you need
+
+Example:
+```elixir
+config :pleroma, Pleroma.Web.Endpoint,
+  url: [host: "example.com", port: 2020, scheme: "https"],
+  http: [
+    # start copied from config.exs
+    dispatch: [
+      {:_,
+       [
+         {"/api/v1/streaming", Pleroma.Web.MastodonAPI.WebsocketHandler, []},
+         {"/websocket", Phoenix.Endpoint.CowboyWebSocket,
+          {Phoenix.Transports.WebSocket,
+           {Pleroma.Web.Endpoint, Pleroma.Web.UserSocket, websocket_config}}},
+         {:_, Phoenix.Endpoint.Cowboy2Handler, {Pleroma.Web.Endpoint, []}}
+       ]}
+    # end copied from config.exs
+    ],
+    port: 8080,
+    ip: {127, 0, 0, 1}

+their ActivityPub ID.
+
+An example:
+
+```elixir
+config :pleroma, :mrf_user_allowlist,
+  "example.org": ["https://example.org/users/admin"]
+```
+
+## :web_push_encryption, :vapid_details
+
+Web Push Notifications configuration. You can use the mix task `mix web_push.gen.keypair` to generate it.
+
+* ``subject``: a mailto link for the administrative contact. It’s best if this email is not a personal email address, but rather a group email so that if a person leaves an organization, is unavailable for an extended period, or otherwise can’t respond, someone else on the list can.

+
+```elixir
+config :pleroma, :admin_token, "somerandomtoken"
+```
+
+You can then do
+
+```sh
+curl "http://localhost:4000/api/pleroma/admin/invite_token?admin_token=somerandomtoken"
+```
+
+## Oban
+
+[Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
+
+Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
+* `repo` - app's Ecto repo (`Pleroma.Repo`)
+* `verbose` - logs verbosity
+* `prune` - non-retryable jobs [pruning settings](https://github.com/sorentwo/oban#pruning) (`:disabled` / `{:maxlen, value}` / `{:maxage, value}`)
+* `queues` - job queues (see below)
+
+Pleroma has the following queues:
+
+* `activity_expiration` - Activity expiration
+* `federator_outgoing` - Outgoing federation
+* `federator_incoming` - Incoming federation
+* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
+* `transmogrifier` - Transmogrifier
+* `web_push` - Web push notifications
+* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
+
+Example:
+
+```elixir
+config :pleroma, Oban,
+  repo: Pleroma.Repo,
+  verbose: false,
+  prune: {:maxlen, 1500},
+  queues: [
+    federator_incoming: 50,
+    federator_outgoing: 50
+  ]
+```
+
+This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the number of max concurrent jobs set to `50`.
+
+### Migrating `pleroma_job_queue` settings
+
+`config :pleroma_job_queue, :queues` is replaced by `config :pleroma, Oban, :queues` and uses the same format (keys are queues' names, values are max concurrent jobs numbers).
+
+### Note on running with PostgreSQL in silent mode
+
+If you are running PostgreSQL in [`silent_mode`](https://postgresqlco.nf/en/doc/param/silent_mode?version=9.1), it's advised to set [`log_destination`](https://postgresqlco.nf/en/doc/param/log_destination?version=9.1) to `syslog`, 
+otherwise `postmaster.log` file may grow because of "you don't own a lock of type ShareLock" warnings (see https://github.com/sorentwo/oban/issues/52). 
+
+## :workers
+
+Includes custom worker options not interpretable directly by `Oban`.
+
+* `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
+
+Example:
+
+```elixir
+config :pleroma, :workers,
+  retries: [
+    federator_incoming: 5,
+    federator_outgoing: 5
+  ]
+```
+
+### Migrating `Pleroma.Web.Federator.RetryQueue` settings
+
+* `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
+* `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`
+* deprecated options: `max_jobs`, `initial_timeout`
+
+## Pleroma.Web.Metadata
+* `providers`: a list of metadata providers to enable. Providers available:
+  * Pleroma.Web.Metadata.Providers.OpenGraph

+* `unfurl_nsfw`: If set to `true` nsfw attachments will be shown in previews
+
+## :rich_media
+* `enabled`: if enabled the instance will parse metadata from attached links to generate link previews
+* `ignore_hosts`: list of hosts which will be ignored by the metadata parser. For example `["accounts.google.com", "xss.website"]`, defaults to `[]`.
+* `ignore_tld`: list TLDs (top-level domains) which will ignore for parse metadata. default is ["local", "localdomain", "lan"]
+* `parsers`: list of Rich Media parsers
+
+## :fetch_initial_posts
+* `enabled`: if enabled, when a new user is federated with, fetch some of their latest posts
+* `pages`: the amount of pages to fetch
+
+## :hackney_pools
+
+Advanced. Tweaks Hackney (http client) connections pools.
+
+There's three pools used:
+
+* `:federation` for the federation jobs.
+  You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
+* `:media` for rich media, media proxy
+* `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
+
+For each pool, the options are:
+
+* `max_connections` - how much connections a pool can hold
+* `timeout` - retention duration for connections
+
+## :auto_linker
+
+Configuration for the `auto_linker` library:
+
+* `class: "auto-linker"` - specify the class to be added to the generated link. false to clear
+* `rel: "noopener noreferrer"` - override the rel attribute. false to clear
+* `new_window: true` - set to false to remove `target='_blank'` attribute
+* `scheme: false` - Set to true to link urls with schema `http://google.com`
+* `truncate: false` - Set to a number to truncate urls longer then the number. Truncated urls will end in `..`
+* `strip_prefix: true` - Strip the scheme prefix
+* `extra: false` - link urls with rarely used schemes (magnet, ipfs, irc, etc.)
+
+Example:
+
+```elixir
+config :auto_linker,
+  opts: [
+    scheme: true,
+    extra: true,
+    class: false,
+    strip_prefix: false,
+    new_window: false,
+    rel: false
+  ]
+```
+
+## Pleroma.Scheduler
+
+Configuration for [Quantum](https://github.com/quantum-elixir/quantum-core) jobs scheduler.
+
+See [Quantum readme](https://github.com/quantum-elixir/quantum-core#usage) for the list of supported options. 
+
+Example:
+
+```elixir
+config :pleroma, Pleroma.Scheduler,
+  global: true,
+  overlap: true,
+  timezone: :utc,
+  jobs: [{"0 */6 * * * *", {Pleroma.Web.Websub, :refresh_subscriptions, []}}]
+```
+
+The above example defines a single job which invokes `Pleroma.Web.Websub.refresh_subscriptions()` every 6 hours ("0 */6 * * * *", [crontab format](https://en.wikipedia.org/wiki/Cron)).
+
+## Pleroma.ScheduledActivity
+
+* `daily_user_limit`: the number of scheduled activities a user is allowed to create in a single day (Default: `25`)
+* `total_user_limit`: the number of scheduled activities a user is allowed to create in total (Default: `300`)
+* `enabled`: whether scheduled activities are sent to the job queue to be executed
+
+## Pleroma.ActivityExpiration
+
+# `enabled`: whether expired activities will be sent to the job queue to be deleted
+
+## Pleroma.Web.Auth.Authenticator
+
+* `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator
+* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication
+
+## :ldap
+
+Use LDAP for user authentication.  When a user logs in to the Pleroma
+instance, the name and password will be verified by trying to authenticate
+(bind) to an LDAP server.  If a user exists in the LDAP directory but there
+is no account with the same name yet on the Pleroma instance then a new
+Pleroma account will be created with the same name as the LDAP user name.
+
+* `enabled`: enables LDAP authentication
+* `host`: LDAP server hostname
+* `port`: LDAP port, e.g. 389 or 636
+* `ssl`: true to use SSL, usually implies the port 636
+* `sslopts`: additional SSL options
+* `tls`: true to start TLS, usually implies the port 389
+* `tlsopts`: additional TLS options
+* `base`: LDAP base, e.g. "dc=example,dc=com"
+* `uid`: LDAP attribute name to authenticate the user, e.g. when "cn", the filter will be "cn=username,base"
+
+## BBS / SSH access
+
+To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
+
+```exs
+app_dir = File.cwd!
+priv_dir = Path.join([app_dir, "priv/ssh_keys"])
+
+config :esshd,
+  enabled: true,
+  priv_dir: priv_dir,
+  handler: "Pleroma.BBS.Handler",
+  port: 10_022,
+  password_authenticator: "Pleroma.BBS.Authenticator"
+```
+
+Feel free to adjust the priv_dir and port number. Then you will have to create the key for the keys (in the example `priv/ssh_keys`) and create the host keys with `ssh-keygen -m PEM -N "" -b 2048 -t rsa -f ssh_host_rsa_key`. After restarting, you should be able to connect to your Pleroma instance with `ssh username@server -p $PORT`
+
+## :auth
+
+* `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator
+* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication
+
+Authentication / authorization settings.

+* `auth_template`: authentication form template. By default it's `show.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/show.html.eex`.
+* `oauth_consumer_template`: OAuth consumer mode authentication form template. By default it's `consumer.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/consumer.html.eex`.
+* `oauth_consumer_strategies`: the list of enabled OAuth consumer strategies; by default it's set by `OAUTH_CONSUMER_STRATEGIES` environment variable. Each entry in this space-delimited string should be of format `<strategy>` or `<strategy>:<dependency>` (e.g. `twitter` or `keycloak:ueberauth_keycloak_strategy` in case dependency is named differently than `ueberauth_<strategy>`).
+
+## :email_notifications
+
+Email notifications settings.
+
+  - digest - emails of "what you've missed" for users who have been
+    inactive for a while.
+    - active: globally enable or disable digest emails
+    - schedule: When to send digest email, in [crontab format](https://en.wikipedia.org/wiki/Cron).
+      "0 0 * * 0" is the default, meaning "once a week at midnight on Sunday morning"
+    - interval: Minimum interval between digest emails to one user
+    - inactivity_threshold: Minimum user inactivity threshold
+
+## Pleroma.Emails.UserEmail
+
+- `:logo` - a path to a custom logo. Set it to `nil` to use the default Pleroma logo.
+- `:styling` - a map with color settings for email templates.
+
+## OAuth consumer mode
+
+OAuth consumer mode allows sign in / sign up via external OAuth providers (e.g. Twitter, Facebook, Google, Microsoft, etc.).
+Implementation is based on Ueberauth; see the list of [available strategies](https://github.com/ueberauth/ueberauth/wiki/List-of-Strategies).
+
+Note: each strategy is shipped as a separate dependency; in order to get the strategies, run `OAUTH_CONSUMER_STRATEGIES="..." mix deps.get`,
+e.g. `OAUTH_CONSUMER_STRATEGIES="twitter facebook google microsoft" mix deps.get`.
+The server should also be started with `OAUTH_CONSUMER_STRATEGIES="..." mix phx.server` in case you enable any strategies.
+
+Note: each strategy requires separate setup (on external provider side and Pleroma side). Below are the guidelines on setting up most popular strategies.
+
+Note: make sure that `"SameSite=Lax"` is set in `extra_cookie_attrs` when you have this feature enabled. OAuth consumer mode will not work with `"SameSite=Strict"`
+
+* For Twitter, [register an app](https://developer.twitter.com/en/apps), configure callback URL to https://<your_host>/oauth/twitter/callback
+
+* For Facebook, [register an app](https://developers.facebook.com/apps), configure callback URL to https://<your_host>/oauth/facebook/callback, enable Facebook Login service at https://developers.facebook.com/apps/<app_id>/fb-login/settings/
+
+* For Google, [register an app](https://console.developers.google.com), configure callback URL to https://<your_host>/oauth/google/callback
+
+* For Microsoft, [register an app](https://portal.azure.com), configure callback URL to https://<your_host>/oauth/microsoft/callback
+
+Once the app is configured on external OAuth provider side, add app's credentials and strategy-specific settings (if any — e.g. see Microsoft below) to `config/prod.secret.exs`,
+per strategy's documentation (e.g. [ueberauth_twitter](https://github.com/ueberauth/ueberauth_twitter)). Example config basing on environment variables:
+
+```elixir
+# Twitter
+config :ueberauth, Ueberauth.Strategy.Twitter.OAuth,
+  consumer_key: System.get_env("TWITTER_CONSUMER_KEY"),
+  consumer_secret: System.get_env("TWITTER_CONSUMER_SECRET")

+## Database options
+
+### RUM indexing for full text search
+* `rum_enabled`: If RUM indexes should be used. Defaults to `false`.
+
+RUM indexes are an alternative indexing scheme that is not included in PostgreSQL by default. While they may eventually be mainlined, for now they have to be installed as a PostgreSQL extension from https://github.com/postgrespro/rum.
+
+Their advantage over the standard GIN indexes is that they allow efficient ordering of search results by timestamp, which makes search queries a lot faster on larger servers, by one or two orders of magnitude. They take up around 3 times as much space as GIN indexes.
+
+To enable them, both the `rum_enabled` flag has to be set and the following special migration has to be run:
+
+`mix ecto.migrate --migrations-path priv/repo/optional_migrations/rum_indexing/`
+
+This will probably take a long time.
+
+## :rate_limit
+
+This is an advanced feature and disabled by default.
+
+A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
+
+* The first element: `scale` (Integer). The time scale in milliseconds.
+* The second element: `limit` (Integer). How many requests to limit in the time scale provided.
+
+It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
+
+See [`Pleroma.Plugs.RateLimiter`](Pleroma.Plugs.RateLimiter.html) documentation for examples.
+
+Supported rate limiters:
+
+* `:search` for the search requests (account & status search etc.)
+* `:app_account_creation` for registering user accounts from the same IP address
+* `:relations_actions` for actions on relations with all users (follow, unfollow)
+* `:relation_id_action` for actions on relation with a specific user (follow, unfollow)
+* `:statuses_actions` for create / delete / fav / unfav / reblog / unreblog actions on any statuses
+* `:status_id_action` for fav / unfav or reblog / unreblog actions on the same status by the same user
+
+## :web_cache_ttl
+
+The expiration time for the web responses cache. Values should be in milliseconds or `nil` to disable expiration.
+
+Available caches:
+
+* `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
+* `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).
