Mitchell Hashimoto	8a9e1c1527	dag: call into DotNode to get attributes	10 years ago
James Bardin	6d30b60144	Add DebugVisitInfo ... This encodes vertex debug information into the graph log when a vertex is visited during a walk operation. These can ordered to show how the Graph was walked. Add a mutex to the encoder so it can be used during a parallel walk. Moved string literal constants used for marshaling to pre-defined constants. Did some renaming to make the marshal* structures more consistent.	10 years ago
James Bardin	1be8e8c5a0	Add Graph.DebugOperation test	10 years ago
James Bardin	7e66df3290	Rename annotation methods ... Change AnnotateVertex and AnnotateEdge to VertexDebugInfo EdgeDebugInfo to avoid confusion between debug output and future graph annotations.	10 years ago
James Bardin	f37b2fafed	Remove sync.Once from dag.Graph ... dag.Graph is used as a value, but contains a sync data structure. This prevents copying the value, and is needed if one wants to upgrade a Graph to an AcyclicGraph. The sync.Once only guards the init() method, which can be guarded internally with nil checks on the fields. The init method could be removed entirely with a proper constructor later on of we so choose.	10 years ago
James Bardin	7bbd6bfbd7	Add methods to annotate Graph vertices and edges ... The AnnotateVertex and AnnotateEdge Graph methods will allow terraform to insert arbitray information into the encoded graph stream for later processing.	10 years ago
James Bardin	82b1a2abc2	Add graph transformation recording ... The external api provided here is simply dag.Graph.SetDebugWriter(io.Writer). When a writer is provided to a Graph, it will immediately encode itself to the stream, and subsequently encode any additional transformations to the graph. This will allow easier logging of graph transformations without writing complete graphs to the logs at every step. Since the marshalGraph can also be dot encoded, this will allow translation from the JSON logs to dot graphs.	10 years ago
