DaemonState

Struct DaemonState 

Source
pub struct DaemonState {
    pub config: DaemonConfig,
    pub audit: Arc<dyn AuditStore>,
    pub policy: PolicyTable,
    pub host_distro: Option<DistroId>,
    pub forwarder: Option<AuditForwarder>,
    pub running_high_risk_reboot: Arc<Mutex<Option<String>>>,
}

Fields§

§config: DaemonConfig§audit: Arc<dyn AuditStore>

Polymorphic audit store. Concrete impls: SqliteStore (default) and PostgresStore (selected via [storage] backend = "postgres"). Both implement AuditStore async trait.

§policy: PolicyTable§host_distro: Option<DistroId>

Strict host identity used to enforce the documented support matrix at preview and execution boundaries.

§forwarder: Option<AuditForwarder>

Optional external audit-log forwarder. None when no [audit.forward] sink is configured; events recorded by the dispatcher are then only written to the local hash-chained store.

§running_high_risk_reboot: Arc<Mutex<Option<String>>>

Coarse concurrency guard for High-risk reboot-required actions (ME4).

Holds the request_hash of any currently executing action whose ActionSpec has risk_level == High && reboot_required == true (e.g. UbuntuReleaseUpgrade, AddLayeredPackage, RebaseSystem). None when no such action is in flight.

The guard is one-directional, not mutual exclusion between all mutating actions: every mutating action checks this slot before it is allowed to start, but only a High-risk + reboot-required action ever claims it (sets it to Some). So while a High-risk + reboot-required action is in flight, every other mutating action — including another High-risk + reboot-required one — is rejected with a ConflictResponse rather than racing the in-flight upgrade and causing dpkg/rpm-ostree lock contention. An ordinary mutating action (e.g. StartService) never claims the slot itself, so it neither blocks other ordinary mutating actions nor blocks a High-risk + reboot-required action that starts while it is still running.

The slot is Arc<Mutex<…>> so cloned DaemonState values — one per IPC connection — all share the same underlying guard. Mutex::lock is held for at most a few microseconds; this does not become a hot-path bottleneck because read-only actions skip the check entirely.

On daemon crash the in-memory guard is lost. That is correct: the daemon’s SQLite store will show the orphaned Running row; the operator can inspect it via ListJobHistory.

Implementations§

Source§

impl DaemonState

Source

pub fn open(config: DaemonConfig) -> Result<Self, DaemonStateError>

Open the daemon state with no policy overrides and no forwarding. Suitable for tests and dev runs.

Source

pub fn open_with_policy( config: DaemonConfig, policy: PolicyTable, ) -> Result<Self, DaemonStateError>

Open the daemon state with an explicit policy table and no forwarding.

Source

pub fn open_full( config: DaemonConfig, policy: PolicyTable, forwarder: Option<AuditForwarder>, ) -> Result<Self, DaemonStateError>

Open the daemon state with full configuration. Production callers (main.rs) build the policy table from [policy.risk_overrides] and the forwarder from [audit.forward]. The audit store defaults to SQLite at config.database_path; pass an explicit audit to use Postgres or any other AuditStore impl.

Source

pub fn open_with_audit( config: DaemonConfig, policy: PolicyTable, forwarder: Option<AuditForwarder>, audit: Arc<dyn AuditStore>, ) -> Self

Open the daemon state with an explicit audit store. Used by main.rs when [storage] backend = "postgres" is configured: the Postgres AuditStore is constructed via PostgresStore::connect and passed here as the audit argument.

Source

pub fn bootstrap( config: DaemonConfig, ) -> Result<DaemonRuntime, DaemonStateError>
