Crate solid_pod_rs_server 

solid-pod-rs-server

Drop-in Solid Pod server binary wrapping solid-pod-rs with actix-web. This crate is both a library (for integration-test reuse) and a binary.

Public types

• AppState — Shared actix-web application state (storage, dotfile policy, body cap).
• build_app — Builds the fully-configured actix_web::App with all routes and middleware.
• NodeInfoMeta — NodeInfo 2.1 metadata inputs.
• PathTraversalGuard — Middleware that rejects .. path-traversal attempts.
• DotfileGuard — Middleware that enforces the dotfile allowlist.
• ErrorLoggingMiddleware — Middleware that logs 5xx responses with full error chains.
• body_cap_from_env — Reads JSS_MAX_REQUEST_BODY from the environment.
• cli — CLI argument definitions (clap derive).

Middleware stack (applied in order)

1. NormalizePath – collapse // and decode %-encoded segments.
2. PathTraversalGuard – defence-in-depth .. re-check.
3. DotfileGuard – rejects .env etc unless on the allowlist.
4. PayloadConfig – enforces JSS_MAX_REQUEST_BODY body cap.
5. ErrorLoggingMiddleware – structured 5xx logging.
6. WAC-on-write – PUT/POST/PATCH/DELETE require a write/append grant.

solid-pod-rs-server

Binary distribution of solid-pod-rs — a drop-in JSS replacement that runs as a single static-ish Rust binary.

Install

Once published to crates.io (target: v0.4.0):

cargo install solid-pod-rs-server
solid-pod-rs-server --config config.json

Until then, build from source:

cargo build --release -p solid-pod-rs-server
./target/release/solid-pod-rs-server --help

Architecture

This crate is a thin binary shell over solid-pod-rs. Per ADR-056 §D3 (F7 library-server split):

• solid-pod-rs — pure library. No #[tokio::main], no actix-web::HttpServer. Framework-agnostic.
• solid-pod-rs-server (this crate) — owns the actix-web HTTP server, the tokio runtime, clap CLI, the F6 layered config loader, and signal handling. Depends on the library and wires its PodService-style primitives into concrete HTTP routes.

Configuration

Configuration is loaded by solid_pod_rs::config::ConfigLoader (F6, PRD §F6). Precedence (later overrides earlier):

Defaults  <  File  <  EnvVars  <  CLI flags

See crates/solid-pod-rs/src/config/sources.rs for the full JSS_* environment variable table.

Feature flags

This binary enables the following solid-pod-rs features by default:

Feature	Purpose
fs-backend	Filesystem storage (JSS default)
memory-backend	In-memory storage (test / dev)
config-loader	F6 layered config loader
legacy-notifications	F3 solid-0.1 WS notifications adapter

Other feature flags (oidc, dpop-replay-cache, nip98-schnorr, s3-backend) can be opted into by the operator via a custom build.

Licence

AGPL-3.0-only. See LICENSE. Operating this binary as a network service triggers AGPL §13 source-disclosure obligations.

Modules

cli

CLI argument definitions (clap derive structs). Operator CLI subcommands — Sprint 11 rows 138, 163, 168.

Structs

AppState

Actix-web shared state.

DotfileGuard

Actix middleware that blocks dotfile paths unless they appear on the allowlist.

DotfileGuardMiddleware

Per-request service instance produced by DotfileGuard.

ErrorLoggingMiddleware

Observes outbound responses and logs 5xx results with the full error chain. Pass-through on 2xx/3xx/4xx. Shaped as an actix Transform so it slots into the middleware stack in build_app.

ErrorLoggingMiddlewareService

Per-request service instance produced by ErrorLoggingMiddleware.

NodeInfoMeta

NodeInfo 2.1 body inputs. Kept here so tests can override them.

PathTraversalGuard

Actix middleware that rejects requests containing .. path-traversal sequences.

PathTraversalGuardMiddleware

Per-request service instance produced by PathTraversalGuard.

Constants

DEFAULT_BODY_CAP

Discover the body cap from the environment. Accepts values like 50MB, 1.5GB, or a bare integer (bytes). Falls back to 50 MiB.

Functions

body_cap_from_env

Read JSS_MAX_REQUEST_BODY and parse via parse_size. On any failure, returns DEFAULT_BODY_CAP.

build_app

Build the complete actix App for the Solid Pod server. Both the binary (main.rs) and the workspace integration tests call this.
