Enum CommitStatusProviderRequest

pub enum CommitStatusProviderRequest {
    IsCurrentSystemCommitted {
        responder: CommitStatusProviderIsCurrentSystemCommittedResponder,
    },
}

A reporter for whether the currently booted system is committed. When an update is committed, this means:

• The currently booted slot is marked as healthy (e.g. successfully booted).
• The alternate slot (if present) is marked as unbootable.
• The system will not roll back to the previous version of the OS on reboot.
• The previous version of the OS may be garbage collected.

Until the update is committed, the system retains the prior version of the OS. That way, if we discover the newly written version is bad (e.g. it cannot itself update), then the system can fall back to the previous committed version.

Variants

IsCurrentSystemCommitted

Determines whether the currently booted system is committed, and immediately returns an EventPair.

• If the currently booted system is committed, the ZX_USER_SIGNAL_0 signal is asserted on the EventPair, e.g. the signal is asserted before the EventPair is returned.
• If the commit is pending, no signals are asserted on the EventPair. When the system is committed, ZX_USER_SIGNAL_0 is asserted on the EventPair.
• If the system fails to commit the currently booted version, the system will reboot and terminate the component serving [CommitStatusProvider], which will assert ZX_EVENTPAIR_PEER_CLOSED. At this point, any remaining EventPairs will observe the ZX_EVENTPAIR_PEER_CLOSED signal.

• response event an EventPair with rights ZX_RIGHTS_BASIC.
