Function Documentation

checkOutputs()

void nix::checkOutputs	(	Store &	store,
		const StorePath &	drvPath,
		const decltype(Derivation::outputs) &	drvOutputs,
		const decltype(DerivationOptions::outputChecks) &	drvOptions,
		const std::map< std::string, ValidPathInfo > &	outputs )

Check that outputs meets the requirements specified by the 'outputChecks' attribute (or the legacy '{allowed,disallowed}{References,Requisites}' attributes).

The outputs may not be valid yet, hence outputs needs to contain all needed info like the NAR size. However, the external (not other output) references of the output must be valid, so we can compute the closure size.
