- crud is now the demonstrator: app owns smarm runtime + root supervisor,
store actor and urus::endpoint as ordered siblings (store first, so
reverse-order shutdown drains HTTP before stopping the store),
Shutdown::Infinity on the endpoint, shutdown via
rt.handle().request_shutdown(root_sup) from the stdin thread.
Deletes two kludges the old shape forced:
* static OnceLock<Sender> spawn-on-first-use -> a supervised child
that self-registers a typed Name; handlers use smarm::send per
request and turn 'between incarnations' into a 503 instead of
panicking on a dropped store.
* static SHUTTING_DOWN AtomicBool + 250ms recv_timeout poll in the
store loop and in the SSE ticker -> a plain park; the tree stops
both. Smoke-tested live: CRUD round-trips, SSE stream, clean drain
with the stream open, port closed after.
- Other examples stay short and on serve*, updated for the split config
(serve_with(cfg, smarm::Config, pipe) / serve_with_shutdown(..., signal)).
plain_serve's URUS_SCHED_THREADS now builds a smarm::Config.
ws_chat's doc block explains the OnceLock is a serve*-only workaround
and points at crud for the clean shape.
- README: new 'Your Own Supervision Tree' section (endpoint as the real
API), graceful shutdown reframed as the serve*-only path, Config table
loses scheduler_threads and gains name, PubSub rule 1 notes the
supervised-sibling alternative.
111 lib + 50 integration + 2 doc tests green; clippy clean.
A file-based way to set tuning knobs without recompiling. urus is a
library, so it never presumes a config path or reads the environment — the
binary hands the text in:
- Config::with_toml_str(&str) -> Result<Config, ConfigError>: sparse overlay
onto an existing Config (built with the addr the binary chose). Only keys
present are applied; durations are integer seconds; unknown keys are a
hard error (deny_unknown_fields) so a typo is loud, not a silent no-op.
- Scope: the four slowloris knobs (head_timeout_secs, body_timeout_secs,
body_burst_bytes, body_stall_timeout_secs). Migrating the rest of Config
into the file is a separate, additive job — TomlOverrides just grows.
- Feature `config-file = ["dep:serde", "dep:toml"]`; the optional serde dep
gains the derive feature. The default build is unchanged (deps + code are
all gated).
- examples/serve_toml.rs (required-features = ["config-file"]): a `--config
PATH` demo with no presumed default location. plain_serve and its env
vars are left untouched.
Tests (feature-gated): empty keeps defaults, partial overrides only named,
full overrides all, unknown key errors, malformed errors. 84 lib with the
feature / 79 without; clippy --lib clean both ways; e2e smoke serves 200
from a file and rejects an unknown key loudly.
