Petr Houška b6d5c2ecdc fix(env): kill the daemon's commands when it is terminated 
Connection.close() ends stdin and sends SIGTERM at once. The daemon did not
handle SIGTERM, so it died before its end-of-input kill_all, and running
commands were reparented to init. The daemon now blocks SIGTERM, SIGINT and
SIGHUP before starting any thread and waits for them on its own thread, which
kills every process group it started and exits. On Windows the job object
already kills commands with the daemon.

Changelog

[Unreleased]

Breaking Changes

  • RemoteWatcher follows Durable's FileWatcher: close(context) is stop(context), and its changes are tagged ({ kind: "paths", paths }, { kind: "overflow" }, { kind: "failed", error }). The daemon's watch protocol is unchanged. Migration: await watcher.close(ctx) becomes await watcher.stop(ctx); test change.kind instead of "overflow" in change or "error" in change.

Fixed

  • exec and pty fail with spawn_error instead of hanging when the daemon cannot start a helper thread (for example at a cgroup task limit); the started command is killed and reaped (#11433).
  • Connection.close() on Unix no longer leaves running commands behind: the daemon used to die from the client's SIGTERM before killing its process groups. It now kills them on SIGTERM, SIGINT or SIGHUP before exiting.

[1.4.0] - 2026-10-21

[1.3.0] - 2026-10-15

[1.2.0] - 2026-10-12

Added

  • The daemon's listFiles operation: a bounded, cancellable, gitignore-aware listing of a directory tree (files, directories and unfollowed symlinks); hello reports it in features, and older daemons answer not_supported without a request.
  • RemoteExecutionEnv.listFiles and LocalExecutionEnv, a local ExecutionEnv on a pi-env daemon connection with the same operations.
  • nodePlatform(info) maps the daemon's platform and architecture names to Node's.
  • Pseudo-terminals for interactive programs: the daemon's pty, ptyWrite, and ptyResize operations stream raw terminal output as events, write input in arrival order, send SIGWINCH on resize, and kill the process group on cancel or a lost connection. openTerminal() returns a RemoteTerminal, and localDaemon() starts the daemon for this machine. Unix only; Windows answers ENOTSUP.
  • RemoteTerminal.foreground() (daemon ptyForeground) reports the process group in front of a terminal when it is not the program's own, such as a job its shell runs, with the leader's name on macOS and Linux (TerminalForeground).

[1.1.0] - 2026-10-07

[1.0.4] - 2026-10-05

Added

  • Initial release of @earendil-works/pi-env: RemoteExecutionEnv, a Durable ExecutionEnv on another machine, and Connection to the pi-env daemon that runs there. Results match NodeExecutionEnv on that machine on Linux, macOS, Android and Windows. The daemon watches files natively (polling on Windows and network file systems), honors output windows so dropped command output is not transferred, and keeps control replies ahead of bulk output; watchers report overflow and resume after a lost connection.
  • SSH bootstrap: connectSsh detects the remote system, deploys the daemon this package ships for it (named by its SHA-256 and verified before every start), and connects; sshConnection does the same lazily at the first operation, so building an environment never needs the network without forwarding, shared connections or configured commands; loginShell starts it through the user's login shell, and Termux hosts get setup warnings. scanHostKey, acceptHostKey and forgetHostKey manage trusted host keys; a changed key is never accepted without removing the old one.
