Full Rust implementation of the warpgate NAS cache proxy:
- CLI: clap-based with subcommands (run, setup, status, cache, warmup,
bwlimit, speed-test, config-init, log)
- Config: TOML-based with env var override, preset templates
- rclone: VFS mount args builder, config generator, RC API client
- Services: Samba config gen, NFS exports, WebDAV serve args, systemd units
- Deploy: dependency checker, filesystem validation, one-click setup
- Supervisor: single-process tree managing rclone mount + smbd + WebDAV
as child processes — no systemd dependency for protocol management
Supervisor hardening:
- ProtocolChildren Drop impl prevents orphaned processes on startup failure
- Early rclone exit detection in mount wait loop (fail fast, not 30s timeout)
- Graceful SIGTERM → 3s grace → SIGKILL (prevents orphaned smbd workers)
- RestartTracker with 5-min stability reset and linear backoff (2s/4s/6s)
- Shutdown signal checked during mount wait and before protocol start
