Paul Hinze	baa33d7326	core: dag errors should cascade to all descendents We weren't marking skipped nodes as failing, so any grandchild-and-deeper dependencies would still evaluate. For example: A -> B -> C -> D If B failed, C would be skipped, but D would still be evaluated. This fixes the behavior so C, D, and any further descendents will all be skipped when B fails. Addresses crashing aspect of #2955 and likely a lot of other confusing failure modes.	11 years ago
Paul Hinze	ce49dd6080	core: graph command gets -verbose and -draw-cycles When you specify `-verbose` you'll get the whole graph of operations, which gives a better idea of the operations terraform performs and in what order. The DOT graph is now generated with a small internal library instead of simple string building. This allows us to ensure the graph generation is as consistent as possible, among other benefits. We set `newrank = true` in the graph, which I've found does just as good a job organizing things visually as manually attempting to rank the nodes based on depth. This also fixes `-module-depth`, which was broken post-AST refector. Modules are now expanded into subgraphs with labels and borders. We have yet to regain the plan graphing functionality, so I removed that from the docs for now. Finally, if `-draw-cycles` is added, extra colored edges will be drawn to indicate the path of any cycles detected in the graph. A notable implementation change included here is that {Reverse,}DepthFirstWalk has been made deterministic. (Before it was dependent on `map` ordering.) This turned out to be unnecessary to gain determinism in the final DOT-level implementation, but it seemed a desirable enough of a property that I left it in.	11 years ago
Paul Hinze	97acccd3ed	core: targeted operations Add `-target=resource` flag to core operations, allowing users to target specific resources in their infrastructure. When `-target` is used, the operation will only apply to that resource and its dependencies. The calculated dependencies are different depending on whether we're running a normal operation or a `terraform destroy`. Generally, "dependencies" refers to ancestors: resources falling _before_ the target in the graph, because their changes are required to accurately act on the target. For destroys, "dependencies" are descendents: those resources which fall _after_ the target. These resources depend on our target, which is going to be destroyed, so they should also be destroyed.	11 years ago
