调研方向

Start by reading the WASM shell stdin redirection issue #1657 and trace how guest commands are parsed and how stdin reaches the Node process. Reproduce the listed commands in a fresh VM, then locate the shell and Node runtime entry points involved; the issue does not name files or tests. Done means stdin scripts run with and without --input-type=module, unsupported flags report the flag, and /dev/stdin is available.

描述

@rivet-dev/agentos-core 0.4.1, @rivet-dev/agentos-sidecar-linux-x64-gnu 0.2.22, Linux x64. Deterministic: it happens on an idle, fresh VM with no load.

import { AgentOs } from "@rivet-dev/agentos-core";

const vm = await AgentOs.create();
for (const command of [
  "node --input-type=module <<'JS'\nconsole.log('ok')\nJS",
  "echo \"console.log('ok')\" | node --input-type=module",
  "echo \"console.log('ok')\" | node",
  "node <<'JS'\nconsole.log('ok')\nJS",
  "node -e \"process.stdin.on('data', (d) => console.log('got', String(d)))\" <<'X'\nhello\nX",
  "node -e \"require('fs').readFileSync('/dev/stdin', 'utf8')\" < /etc/hostname",
  "node --no-warnings -e 'console.log(1)'",
]) {
  const r = await vm.process.exec(command, { output: { capture: "all" } });
  console.log(JSON.stringify(command), r.exitCode, JSON.stringify(r.stdout + r.stderr));
}
await vm.dispose();
Command Expected Actual
node --input-type=module <<'JS' … JS runs the module, prints ok exit 127, error: command not found: node
echo … | node --input-type=module prints ok exit 127, error: command not found: node
echo … | node / node <<'JS' … JS prints ok exit 0, prints nothing (the program is never run)
process.stdin.on('data') with stdin from a heredoc prints got hello exit 0, prints nothing
readFileSync('/dev/stdin') the input ENOENT … '/dev/stdin'
node --no-warnings -e … prints 1 Cannot find module '/workspace/--no-warnings'

command -v node prints /bin/node, node -e, node file.mjs and readFileSync(0) with piped stdin all work. The first row is the harmful one: coding agents commonly write node --input-type=module <<'JS', get "command not found: node", and conclude Node is not installed, then stop using it for the rest of the session.

Expected: node with no script reads the program from stdin (as node - does), --input-type applies to it, unknown or unsupported flags fail with a message naming the flag rather than as a missing command or module, and /dev/stdin exists.

Possibly related: #1657 (< file stdin redirection in the WASM shell).
