[01/15] incubator-tinkerpop git commit: The most brutal refactor.
There is no such thing as a TraversalSource.Builder anymore. All there are
are TraversalSources. These are simply a wrapper of a TraversalStrategy and a
Graph. There is no such thing as a

+* Refactored `TraversalSource` model to allow fluent-method construction of `TraversalSources`.
+* Deprecated the concept of a `TraversalSource.Builder`.
+* Removed the concept of a `TraversalEngine`. All `Traversal` modulations are now mediated by `TraversalStrategies`. (*breaking*)
+* Added `SideEffectStrategy` for registering sideEffects in a spawned `Traversal`.
+* Added `SackStrategy` for registering a sack for a spawned `Traversal`.
+* Added `RequirementsStrategy` and `RequirementsStep` for adding dynamic `TraverserRequirements` to a `Traversal`.
+* Removed `EngineDependentStrategy`.
+* Renamed step interface `EngineDependent` to `GraphComputing` with method `onGraphComputer()`. (*breaking*)
+* Cleaned up various `TraversalStrategy` tests now that `TraversalEngine` no longer exists.
* Added `GraphFilter` to support filtering out vertices and edges that won't be touched by an OLAP job.
* Added `GraphComputer.vertices()` and `GraphComputer.edges()` for `GraphFilter` construction *(breaking)*.
* `SparkGraphComputer`, `GiraphGraphComputer`, and `TinkerGraphComputer` all support `GraphFilter`.

Upgrading for Providers
~~~~~~~~~~~~~~~~~~~~~~~
+TraversalEngine Deprecation and GraphProvider
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The `TraversalSource` infrastructure has been completely rewritten. Fortunately, for users, their code is backwards compatible.
+Unfortunately, for graph system providers, a few tweaks to their implementation are in order.
+
+* If the graph system provides support for more than `Graph.compute()`, then it implement `GraphProvider.getGraphComputer()`.
+* In any custom `TraversalStrategies`, change `traverser.getEngine().isGraphComputer()` to `traversal.getStrategies().onGraphComputer()`.
+* In any custom `Steps`, change `implements EngineDependent` to `implements GraphComputing`.

Posted by ok...@apache.org.
added back in ComputerTraversalEngine, StandardTraversalEngine, and TraversalSource.Builder. All are deprecated but are functional with respects to Graph.traversal(TravesalSource.Builder). Both TinkerGraphProvider and SparkGraphProvider have a 50-percent chance of either using the new traversal source model or the old deprecated builder model. This way, we are certain that, for users, this push is backwards compatible. Note that for graph system providers, there is only one new method they need to implement in their XXXGraphProvider test code -- getGraphComputer(). Thus, this ticket is extremely gentle on both users and providers even though it is a massive refactor.

Posted by ok...@apache.org.
The most brutal refactor. There is no such thing as a TraversalSource.Builder anymore. All there are are TraversalSources. These are simply a wrapper of a TraversalStrategy and a Graph. There is no such thing as a TraversalEngine anymore. What was ComputerTraversalEngine is now simply a strategy of TraversalVertexProgramStrategy. There is no such thing as EngineDependentStrategy -- this is simply TraversalVertexProgramStrategy. In short, all there are are Graphs and TraversalStrategies. So so so so so much cleaner. This WILL NOT be backwards compatible for graph system providers. They will need to update their GraphProvider implementations -- two methods changed. Moreover, if they have an XXXStrategy that calls traversal.getEngine().isComputer(), they will need to change that to traversal.getStrategies().onGraphComputer(). Really simple to for them to fix. It took me less a minute to fix up Spark, Giraph, and Neo4j. These changes WILL be backwards compatible for users at the level of
graph.traversal(computer(SparkGraphComputer)) still working (though Depcrecation introduced). The GraphTraversal.Builder will simply turn into a bunch of TravesalSource calls. It is not used outside of this context. This commit is NOT complete and will be completed on the next sprint. Moreover, there are lots of cleanups and JavaDocing that I need to do -- I just don't want to lose this work so pushing.

Just realized that numerous tests are excluded because local traversals are being verified as global in ComputerVerificationStrategy. Given that TraversalEngine no longer exists, added TraversalParent.isLocalChild() to test if the child is local or global and updated ComputerVerificationStrategy accordingly.

Posted by ok...@apache.org.
Just realized that numerous tests are excluded because local traversals are being verified as global in ComputerVerificationStrategy. Given that TraversalEngine no longer exists, added TraversalParent.isLocalChild() to test if the child is local or global and updated ComputerVerificationStrategy accordingly.
