TargetSupervisor

Struct TargetSupervisor 

Source
pub struct TargetSupervisor { /* private fields */ }
Expand description

Supervises the two webhook relay targets on demand.

Why: one supervisor across both services rather than one each, so the live-child cap is a statement about console’s whole child population. What: ensure_running keyed by source (review / analyze), with the binary located lazily so an already-running or externally-managed target never requires it to be installed. Test: spawn_adopts_a_socket_that_is_already_served, spawn_maps_each_source_to_its_binary. The external-mode opt-out itself is trusty-common’s external_env_only_honours_exactly_one — console supplies only the variable name, and a test here would have to mutate a process-global env var that every sibling in the binary can see.

Implementations§

Source§

impl TargetSupervisor

Source

pub fn new() -> Self

Build a supervisor for the relay targets.

max_live is 2 — there are exactly two targets, and a cap that reaped one to make room for the other would thrash under a two-source burst.

Source

pub fn spawned_count(&self) -> u64

How many children this supervisor has launched.

Source

pub async fn ensure_running( &self, source: &str, socket: &Path, ) -> Result<PathBuf, SupervisorError>

Ensure something is serving socket for source.

Why: called immediately before a relay, so the socket is bound by the time the frame is written. The supervisor’s own fast path means a target already serving costs one probe, not a spawn.

§Errors

SupervisorError when the binary cannot be found, the spawn fails, or the child never binds. Every one leaves the delivery unrelayed and therefore unacked — the caller records it as Unreachable, which keeps the spool entry.

Test: spawn_adopts_a_socket_that_is_already_served covers the path that resolves no binary; the spawn path itself is covered by trusty-common’s supervisor suite rather than by launching a real trusty-review from a unit test.

Source

pub async fn shutdown(&self)

SIGTERM every child and clean up its socket.
