[1/7] tinkerpop git commit: LazyBarrierStrategy is now a default
strategy and is smart about labels, retractions, flatMaps, barriers,
etc. In short,
all the queries that were given to it are either equal in speed or faster.
[Forced Update!]

+* A new version of `LazyBarrierStrategy` has been created and added to the default strategies.
* `FilterRankStrategy` now propagates labels "right" over non-`Scoping` filters.
* Fixed a bug in `ConnectiveP` where nested equivalent connectives should be inlined.
* Fixed a bug in `IncidentToAdjacentStrategy` where `TreeStep` traversals were allowed.

[2/7] tinkerpop git commit: ProfileTests and LazyBArrierStrategy
don't play well with each other because ProfileTests expect certain
bulks/counts/etc. Thus, if testing and there is ProfileStep,
then the strategy is not applied.
Posted by ok...@apache.org.
ProfileTests and LazyBArrierStrategy don't play well with each other because ProfileTests expect certain bulks/counts/etc. Thus, if testing and there is ProfileStep, then the strategy is not applied.

okay, so no more withStrategies(Map...) and withoutStrategies(String...). Ha. All that for nothing. Not really, so much behind the scenes work on TraversalStrategy bytecode representation and its use with Gremlin variants. Gremlin-Python looks slick with withStrategies(). And we have finally exposed the strategy process tests to variant testing.

Posted by ok...@apache.org.
Talked with @spmallette about making TraversalStrategies first class citizens -- g:ReadOnlyStrategy, etc. This allows us to get rid of the withStrategies(Map...) methods. Now both Gremlin-Python and Gremlin-Java talk in terms of TraversalStrategy instances which can be serialized across the wire via their Configurations. Note that this is the already merged branch name with appended 'redux'.

@@ -30,11 +30,9 @@ TinkerPop 3.2.3 (Release Date: NOT OFFICIALLY RELEASED YET)
* Fixed a `Bytecode` bug where nested structures (map, list, set) were not being analyzed for bindings and bytecode conversions.
* Fixed a `String` bug in `GroovyTranslator` and `PythonTranslator` where if the string has double-quotes it now uses """ """.
* Added a default `TraversalStrategy.getConfiguration()` which returns the configuration needed to construct the strategy.
-* Gremlin-Java `TraversalStrategy` and `Computer` instances are now converted to `Map`-representations in `Bytecode`.
* `Computer` instances can be created with `Computer.create(Configuration)` and accessed via `Computer.getConf()`.
* Every `TraversalStrategy` can be created via a `Configuration` and a static `MyStrategy.create(Configuration)`.
-* Added `TraversalSource.withComputer(Map<String,Object>)` for better language variant support.
-* Added `TraversalSource.withStrategies(Map<String,Object>...)`/`withoutStrategies(String...)` for better language variant support.
+* Added language-agnostic `TraversalStrategy` support in `Bytecode`.
* Added `PartitionStrategy.Builder.readPartitions()` and deprecated `PartitionStrategy.Builder.addPartition()`.
* A new version of `LazyBarrierStrategy` has been created and added to the default strategies.
* `FilterRankStrategy` now propagates labels "right" over non-`Scoping` filters.

TinkerPop 3.2.3 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Fixed a `Set`, `List`, `Map` bug in the various `Translators` where such collections were not being internally translated.
+* Fixed a `Bytecode` bug where nested structures (map, list, set) were not being analyzed for bindings and bytecode conversions.
+* Fixed a `String` bug in `GroovyTranslator` and `PythonTranslator` where if the string has double-quotes it now uses """ """.
+* Added a default `TraversalStrategy.getConfiguration()` which returns the configuration needed to construct the strategy.
+* Gremlin-Java `TraversalStrategy` and `Computer` instances are now converted to `Map`-representations in `Bytecode`.
+* `Computer` instances can be created with `Computer.create(Configuration)` and accessed via `Computer.getConf()`.
+* Every `TraversalStrategy` can be created via a `Configuration` and a static `MyStrategy.create(Configuration)`.
+* Added `TraversalSource.withComputer(Map<String,Object>)` for better language variant support.
+* Added `TraversalSource.withStrategies(Map<String,Object>...)`/`withoutStrategies(String...)` for better language variant support.
+* Added `PartitionStrategy.Builder.readPartitions()` and deprecated `PartitionStrategy.Builder.addPartition()`.
+ * A new version of `LazyBarrierStrategy` has been created and added to the default strategies.
* `FilterRankStrategy` now propagates labels "right" over non-`Scoping` filters.
* Fixed a bug in `ConnectiveP` where nested equivalent connectives should be inlined.
* Fixed a bug in `IncidentToAdjacentStrategy` where `TreeStep` traversals were allowed.
