◆ LoadDyndeps() [2/2]

bool DependencyScan::LoadDyndeps	(	Node *	node,
		std::string *	err ) const

Load a dyndep file from the given node's path and update the build graph with the new information.

One overload accepts a caller-owned 'DyndepFile' object in which to store the information loaded from the dyndep file.

◆ RecomputeDirty()

bool DependencyScan::RecomputeDirty	(	Node *	node,
		std::vector< Node * > *	validation_nodes,
		std::string *	err )

Update the |dirty_| state of the given nodes by transitively inspecting their input edges.

Examine inputs, outputs, and command lines to judge whether an edge needs to be re-run, and update outputs_ready_ and each outputs' |dirty_| state accordingly. Appends any validation nodes found to the nodes parameter. Returns false on failure.
