Struct ShellSessionRegistry 

pub struct ShellSessionRegistry {
    shells: Mutex<HashMap<String, Sender<()>>>,
}

Per-shell stop handles. ShellStop (MCP tool / UI button) looks up a shell_id and fires the oneshot, which makes the owning ShellNodeRunner tree-kill its child. Mirrors InstallSessionRegistry; lives in AppState.shell_sessions. Phase 3 of SPEC_PERSISTENT_SHELL_NODE.

Fields

shells: Mutex<HashMap<String, Sender<()>>>

Implementations

impl ShellSessionRegistry

pub fn new() -> Arc<Self>

fn insert(&self, shell_id: String, tx: Sender<()>)

pub fn stop(&self, shell_id: &str) -> bool

Request stop of a running shell. Returns false if the id is unknown (never started, or already exited). Removing here also closes the window for the runner’s own natural-exit remove.

fn remove(&self, shell_id: &str)

Drop a shell’s handle without signalling — called by the runner on natural exit so its kill_task resolves Err (= not stopped).

pub fn stop_all(&self) -> usize

Stop every running shell. For srv-shutdown cleanup so long-running children (task dev → task.exe/node) don’t orphan and hold ports. Returns the number of shells signalled (so the caller can skip the grace-period sleep when there was nothing to stop).

Trait Implementations

impl Default for ShellSessionRegistry

fn default() -> ShellSessionRegistry

Returns the “default value” for a type.
