All #[allow(dead_code)] annotations on now-used items have been removed
(acceptor.rs, acme.rs, config.rs, static_config.rs). #[non_exhaustive]
added to TlsMode, ProxyError, AdminSocketError, and ValidationError
with wildcard match arms in main.rs for the non-exhaustive enums.
- Replace handle.abort() for HTTPS server tasks with timeout-based join,
allowing in-flight requests to drain before forceful shutdown
- Add shutdown_rx to start_admin_socket with tokio::select! for clean
accept loop exit and Unix socket file cleanup on shutdown
- Add shutdown_rx to start_eviction_task with tokio::select! for
cancellable eviction loop
- Add shutdown channel to spawn_acme_state for cancellable ACME state
machine via tokio::select!
- Pass Arc<GracefulShutdown> through setup_tls to ACME state machine
- Move GracefulShutdown creation before admin socket and TLS setup
- Update integration test for new start_eviction_task signature
Extract strip_port_from_host into shared utils module and update normalize_host to properly strip brackets from IPv6 addresses like [::1]:443 -> ::1 instead of incorrectly using split(':').next().
Adds the HTTP redirect listener that redirects all plain HTTP requests to
the HTTPS equivalent URL. Each listener with http_port > 0 runs its own
redirect server on bind_addr:http_port.
- build_redirect_url: constructs https://{host}:{port}/{path}?{query},
omitting port 443 and stripping the host port from the Host header
- redirect_handler: axum handler returning 301 with Location header,
400 for missing/empty Host, 404 for ACME challenge paths
- redirect_router: creates axum Router with fallback handler
- start_http_redirect_listener: binds TCP and spawns redirect server
- ACME HTTP-01 challenge path returns 404 (placeholder for future)
- 19 unit tests for URL construction and host parsing
- 8 integration tests covering 301 redirect, 400 on missing Host,
port 443 omission, non-443 port inclusion, query preservation,
ACME challenge 404
- Add health.rs module with start_health_check_listener() that binds to
127.0.0.1:{health_check_port} and serves GET /health returning 200 OK
with empty body
- Add health_route() in proxy/handler.rs for HTTPS listener fallback
- Add port conflict detection in config validation: health_check_port
must not conflict with listener ports on 127.0.0.1/localhost/0.0.0.0
- health_check_port = 0 disables the separate listener (handled at call
site)
- Add unit and integration tests for health check functionality
Add ACME TLS module with automatic Let's Encrypt certificate provisioning
and renewal using rustls-acme 0.12. Each listener creates its own AcmeConfig
with domain list, cache directory, and Let's Encrypt directory URL. The ACME
state machine runs as a background tokio task per listener, and
ResolvesServerCertAcme serves the provisioned certificate. Certificate
failure behavior: fail to start without valid cert, continue serving if one
exists. TLS-ALPN-01 is the default challenge type with acme-tls/1 ALPN
registered. Cipher suites restricted to 4 TLS 1.2 + all TLS 1.3 suites.
Also implements manual TLS mode with PEM file loading, SNI-based cert
resolution, and shared CryptoProvider with restricted cipher suites.
