◆ deliver_to_app()

void deliver_to_app	(	pax_machine *	pma,
		app_data_ptr	app,
		delivery_status	app_status
	)

Delivers the app payload to XCom's upper layer, e.g.

GCS.

Please note the following contract regarding the parameter of this function: If app_status is delivery_ok, then it means that XCom reached consensus on app. In this situation, pma MUST point to the Paxos instance (pax_machine) where app got consensus on. In other words, pma MUST NOT be NULL.

In summary, this function is expected to be called as follows if a payload p reached consensus:

deliver_to_app(<pointer to pax_machine where p was decided>, p, delivery_ok)

This function is expected to be called as follows if a payload p did NOT reach consensus:

deliver_to_app(_, p, delivery_failure)

Where the pma argument may be a pointer to the pax_machine where p failed to get consensus, or NULL.

Failure do adhere to this contract will result in an assert failure, at least on non-release builds.

Parameters

pma	The Paxos instance where the `app` payload obtained consensus
app	The payload that was decided for the Paxos instance `pma`
app_status	The reason for `app` delivery: `delivery_ok` if the `app` payload reached consensus on the `pma` Paxos instance, or `delivery_failure` if XCom was unable to reach consensus
