folk-runtime-pipe

Pipe-based PHP worker runtime for Folk.

Spawns each PHP worker via execve, connecting it to the Rust master through two Unix socketpairs:

• FD 3 -> task channel (request/response RPC traffic)
• FD 4 -> control channel (ready/idle/shutdown signals)

Uses pre_exec to set up file descriptors after fork but before exec.

Platform

This crate is Unix-only (#![cfg(unix)]). It does not compile on Windows.

Usage

use folk_runtime_pipe::{PipeConfig, PipeRuntime};

let runtime = PipeRuntime::new(PipeConfig {
    php: "php".into(),
    script: "vendor/bin/folk-worker".into(),
});
