Summary by CodeRabbit

  • New Features
    • Added centralized configuration for the console’s HTTP port and runtime UI preferences.
    • Console port changes now apply live without restarting, with safe fallback behavior if rebinding fails.
    • Added an HTTP port field to the injectable UI settings form, including validation guidance.
    • Console status now reports the currently active port.
  • Bug Fixes
    • Improved listener replacement to preserve the existing connection when a new port cannot be bound.

📝 Walkthrough

Walkthrough

The console now registers http_port with the configuration worker, uses the stored value after startup, and rebinds its HTTP listener when the value changes. The status endpoint reports the live port. The configuration UI exposes the port field and integration tests verify successful and failed rebinding.

Changes

Console live configuration

Layer / File(s) Summary
Configuration schema and runtime reconciliation
console/src/configuration.rs, console/config.yaml, console/iii.worker.yaml, console/src/config.rs, console/README.md
The configuration schema stores a validated http_port. Registration seeds or backfills the value. Runtime updates re-fetch configuration, apply UI preferences, and preserve the existing listener when rebinding fails.
Listener replacement lifecycle
console/src/server.rs
ServerHandle and ServerControl manage listener startup, graceful shutdown, and hard abort after a two-second grace period.
Worker boot and status wiring
console/src/main.rs, console/src/functions/mod.rs, console/tests/integration.rs
Startup fetches the authoritative port before binding. Configuration triggers apply changes under a shared lock. Status reads the current port. Integration tests verify the new listener and retirement of the old listener.
Port configuration UI
console/ui/src/injectable-ui-form/index.tsx, console/ui/styles.css, console/src/ui.rs
The form adds a bounded numeric http_port input and documents live replacement and ephemeral ports. Embedded-form tests check the field.
Estimated code review effort: 4 (Complex) ~60 minutes

Merge Risk: 🔵 Low · up to 347c2

Configuring the console with port 0 can cause status and later updates to use the requested value instead of the actual listening port, leading to incorrect port reporting and reconfiguration behavior. The PR is otherwise mergeable, but this bounded correctness issue should be fixed or explicitly accepted.

Poem

A rabbit tuned the port with care

New listeners sprang through evening air
The old one drained, then hopped away
The form now guides each change by day
“Live config!” sang the rabbit bright

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Store the bound address, not the requested port.

rebind writes the requested new_port into the port cell. The schema allows http_port: 0, and bind_listener(0) returns a kernel-assigned ephemeral port. In that case the snapshot stays 0, so console::status reports 0 and a later update event compares against 0 instead of the live port. ServerControl.local_addr already holds the real address.

The same gap exists at boot in console/src/main.rs: the cell is seeded from cfg.http_port while the ready log uses server_handle.current_addr().

🐛 Proposed fix
     let listener = server::bind_listener(new_port).await?;
     let new_control = server::spawn_server(listener, state.clone());
+    let bound_port = new_control.local_addr.port();
 
     let old = {
         let mut current = control.lock().await;
         if current.is_none() {
             server::stop_old_server(new_control);
             anyhow::bail!("console server is already shut down");
         }
 
-        *port.write().await = new_port;
+        *port.write().await = bound_port;
         current.replace(new_control)
     };
