◆ LoadDyndeps() [1/2]

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() [1/2]

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

Update the |dirty_| state of the given node by inspecting its input edge.

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. Returns false on failure.

bool DependencyScan::RecomputeOutputDirty	(	const Edge *	edge,

		const std::string &	command,
		Node *	output
	)

private

Recompute whether a given single output should be marked dirty.

Returns true if so.

◆ RecomputeOutputsDirty()

bool DependencyScan::RecomputeOutputsDirty	(	Edge *	edge,
		Node *	most_recent_input,
		bool *	dirty,
		std::string *	err

Recompute whether any output of the edge is dirty, if so sets |*dirty|.

Returns false on failure.
