## FedSockets
FedSockets is an experimental feature allowing for Pleroma backends to federate using a persistant websocket connection as opposed to making each federation a seperate http connection. This feature is currently off by default. It is configurable throught he following options.
### :fedsockets
* `enabled`: Enables FedSockets for this instance. `false` by default.
* `connection_duration`: Time an idle websocket is kept open.
* `rejection_duration`: Failures to connect via FedSockets will not be retried for this period of time.
* `fed_socket_fetches` and `fed_socket_rejections`: Settings passed to `cachex` for the fetch registry, and rejection stacks. See `Pleroma.Web.FedSockets` for more details.
## Frontends
### :frontend_configurations ### :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. You can find the documentation for `pleroma_fe` configuration into [Pleroma-FE configuration and customization for instance administrators](/frontend/CONFIGURATION/#options).

defmodule Pleroma.Web.FedSockets do
@moduledoc """
This documents the FedSockets framework. A framework for federating
ActivityPub objects between servers via persistant WebSocket connections.
FedSockets allow servers to authenticate on first contact and maintain that
connection, eliminating the need to authenticate every time data needs to be shared.
## Protocol
FedSockets currently support 2 types of data transfer:
* `publish` method which doesn't require a response
* `fetch` method requires a response be sent
### Publish
The publish operation sends a json encoded map of the shape:
%{action: :publish, data: json}
and accepts (but does not require) a reply of form:
%{"action" => "publish_reply"}
The outgoing params represent
* data: ActivityPub object encoded into json
### Fetch
The fetch operation sends a json encoded map of the shape:
%{action: :fetch, data: id, uuid: fetch_uuid}
and requires a reply of form:
%{"action" => "fetch_reply", "uuid" => uuid, "data" => data}
The outgoing params represent
* id: an ActivityPub object URI
* uuid: a unique uuid generated by the sender
The reply params represent
* data: an ActivityPub object encoded into json
* uuid: the uuid sent along with the fetch request
## Examples
Clients of FedSocket transfers shouldn't need to use any of the functions outside of this module.
A typical publish operation can be performed through the following code, and a fetch operation in a similar manner.
case FedSockets.get_or_create_fed_socket(inbox) do
{:ok, fedsocket} ->
FedSockets.publish(fedsocket, json)
_ ->
alternative_publish(inbox, actor, json, params)
end
## Configuration
FedSockets have the following config settings
config :pleroma, :fed_sockets,
enabled: true,
ping_interval: :timer.seconds(15),
connection_duration: :timer.hours(1),
rejection_duration: :timer.hours(1),
fed_socket_fetches: [
default: 12_000,
interval: 3_000,
lazy: false
]
* enabled - turn FedSockets on or off with this flag. Can be toggled at runtime.
* connection_duration - How long a FedSocket can sit idle before it's culled.
* rejection_duration - After failing to make a FedSocket connection a host will be excluded
from further connections for this amount of time
* fed_socket_fetches - Use these parameters to pass options to the Cachex queue backing the FetchRegistry
* fed_socket_rejections - Use these parameters to pass options to the Cachex queue backing the FedRegistry
Cachex options are
* default: the minimum amount of time a fetch can wait before it times out.
* interval: the interval between checks for timed out entries. This plus the default represent the maximum time allowed
* lazy: leave at false for consistant and fast lookups, set to true for stricter timeout enforcement
