Building & running

Prerequisites

A stable Rust toolchain (cargo, rustc).
OpenSSL development headers for the default TLS backend (the openssl crate links against the system library) — e.g. libssl-dev on Debian/Ubuntu. The optional pure-Rust rustls backend (tls_backend = rustls) needs no system library.

Build

git clone https://git.devtronic.pro/fedserv/echoIRCd
cd echoIRCd

# development build (fast to compile, slow to run)
cargo build

# release build — ALWAYS use this in production; the debug build is unoptimized
# and far slower on the CPU-bound paths (TLS, hashing, cloaking, line parsing)
cargo build --release

The binaries land in target/debug/echoircd and target/release/echoircd.

Run

echoircd takes one argument, the path to a config file (default ./echoircd.conf):

cp echoircd.conf.example echoircd.conf     # then edit: oper pass, cloak_key, TLS paths
cargo run --release                        # reads ./echoircd.conf
# or run the binary directly:
./target/release/echoircd /path/to/echoircd.conf

Point a client at it: /server 127.0.0.1 6667, or 6697 for TLS once a certificate is configured. See configuration for every setting and deployment for running it as a supervised service.

Your live echoircd.conf is gitignored on purpose — it holds secrets (oper password, cloak key, link password). Never commit it.

Tests

cargo test                        # unit + integration tests
cargo test --test integration     # just the end-to-end suite

The integration suite spawns the real binary on ephemeral ports and drives it as a client — covering reactor-pool cross-worker delivery, TLS-in-reactor handshakes, the stalled-handshake reap, the accept-rate limiter, and nick collisions. It tracks and kills its child processes by PID, never by name. The parser and the S2S convergence logic also carry property-based (proptest) suites.

Project layout

src/
  main.rs          startup: config, listeners, the reactor pool, the core thread
  ircd.rs          the core event loop and event types
  server.rs        the Server: all state, plus helpers (send, snotice, off-core work)
  socketengine.rs  the I/O edge: reactor pool, acceptor, TLS-in-reactor, links
  tls.rs           the TLS backend (OpenSSL) — blocking + non-blocking sessions
  channels.rs      Channel, membership, and the channel mode struct
  users.rs         User and session state
  mode.rs          ChanMode / UserMode traits and the mode registry
  command.rs       the Command trait
  module.rs        the module lifecycle-hook trait
  coremods/        built-in commands (registration, channels, messaging, oper, …)
  modules/         optional, pluggable modules (70+ of them)
tests/             end-to-end integration tests
deploy/            production systemd units + firewall script

Extending

Three extension points, each one file plus one table entry:

Commands (src/command.rs, src/coremods/) — a handler with name, min_params, before_reg, and handle(&mut Server, uid, params).
Modes (src/mode.rs) — channel/user modes as ChanMode / UserMode handler objects; adding one never touches the parser.
Modules (src/module.rs, src/modules/) — lifecycle hooks; pre-hooks can Deny a register/command/message, notify-hooks fire after.
