[01/17] tinkerpop git commit: fixed an NPE bug in profiling
GroupSideEffectStep. It has to deal with how GroupSideEffectStep breaks apart
the valueTraversal into a pre/post-traversal for pre-proecessing and
reduction. While I was testing, I found another [Forced Update!]

fixed an NPE bug in profiling GroupSideEffectStep. It has to deal with how GroupSideEffectStep breaks apart the valueTraversal into a pre/post-traversal for pre-proecessing and reduction. While I was testing, I found another bug where if the reducing traversal has no data, then don't .next() it. Basically, it is possible for Profiling to get a traversal that has not been next'd because the traversal's pre/post was being worked with.

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Fixed a `NullPointerException` bug with profiling `GroupSideEffectStep` in OLTP.
* Improved ability to release resources in `GraphProvider` instances in the test suite.
* Added a `force` option for killing sessions without waiting for transaction close or timeout of a currently running job or multiple jobs.
* Deprecated `Session.kill()` and `Session.manualKill()`.

[16/17] tinkerpop git commit: TINKERPOP-1490 Restructured
Traversal.promise()
Posted by sp...@apache.org.
TINKERPOP-1490 Restructured Traversal.promise()
No longer uses an ExecutorService and is only applicable to "remote" traversals. Moved the commons-lang dependency back to gremlin-groovy for now.

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ * Fixed a OLAP `MatchStep.clone()`-bug that occurs when the `match()` is in a local child.
+ * Fixed a bug in `RangeByIsCountStrategy` where labeled parents shouldn't have the strategy applied to their children.
+ * Fixed a bug in `PathRetractionStrategy` where `MatchEndStep` labels were being dropped when they shouldn't be.
* Added `TinkerGraphCountStrategy` which translates `g.V().map*.count()` patterns into direct `Map.size()` calls in `TinkerGraph`.
* Added `Path.head()` and `Path.isEmpty()` with default method implementations.
+* Fixed a `NoSuchElementException` bug with `GroupXXXStep` where if the reduced `TraverserSet` is empty, don't add the key/value.
+* Fixed a `NullPointerException` bug with profiling `GroupSideEffectStep` in OLTP.
* Improved ability to release resources in `GraphProvider` instances in the test suite.
* Added a `force` option for killing sessions without waiting for transaction close or timeout of a currently running job or multiple jobs.
* Deprecated `Session.kill()` and `Session.manualKill()`.

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Added `TinkerGraphCountStrategy` which translates `g.V().map*.count()` patterns into direct `Map.size()` calls in `TinkerGraph`.
+* Added `Path.head()` and `Path.isEmpty()` with default method implementations.
+ * Fixed a `NoSuchElementException` bug with `GroupXXXStep` where if the reduced `TraverserSet` is empty, don't add the key/value.
+ * Fixed a `NullPointerException` bug with profiling `GroupSideEffectStep` in OLTP.
* Improved ability to release resources in `GraphProvider` instances in the test suite.
* Added a `force` option for killing sessions without waiting for transaction close or timeout of a currently running job or multiple jobs.
* Deprecated `Session.kill()` and `Session.manualKill()`.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Fixed a OLAP `MatchStep.clone()`-bug that occurs when the `match()` is in a local child.
+* Fixed a bug in `RangeByIsCountStrategy` where labeled parents shouldn't have the strategy applied to their children.
+* Fixed a bug in `PathRetractionStrategy` where `MatchEndStep` labels were being dropped when they shouldn't be.
* Added `TinkerGraphCountStrategy` which translates `g.V().map*.count()` patterns into direct `Map.size()` calls in `TinkerGraph`.
* Added `Path.head()` and `Path.isEmpty()` with default method implementations.
* Improved ability to release resources in `GraphProvider` instances in the test suite.

[15/17] tinkerpop git commit: TINKERPOP-1490 Implemented promise API
for Traversal
Posted by sp...@apache.org.
TINKERPOP-1490 Implemented promise API for Traversal
Added two promise() methods that return CompletableFuture on Traversal. Provided an override on DefaultTraversal for those methods because the function that transforms the Traversal is executed in a different thread and therefore requires Graph transaction management (or else we would orphan transactions). Did not update gremlin-python with the promise API because it seemed to beg discussion on the "right" way to do that (i.e. what library to use to support promises?, just use futures from the core lib?, etc).

+Traversal Promises
+^^^^^^^^^^^^^^^^^^
+
+The `Traversal` API now has two `promise()` method overloads. These methods return a promise in the form of a
+`CompleteableFuture`. Usage is as follows:
+
+[source,groovy]
+----
+gremlin> promise = g.V().out().promise{it.next()}
+==>java.util.concurrent.CompletableFuture@4aa3d36[Completed normally]
+gremlin> promise.join()
+==>v[3]
+gremlin> promise.isDone()
+==>true
+gremlin> g.V().out().promise{it.toList()}.thenApply{it.size()}.get()
+==>6

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ * Added another optimization in `RangeByIsCountStrategy`, that removes `count().is()` altogether if it's not needed.
* Fixed a OLAP `MatchStep.clone()`-bug that occurs when the `match()` is in a local child.
+* Added another optimization in `RangeByIsCountStrategy`, that removes `count().is()` altogether if it's not needed.
* Fixed a bug in `RangeByIsCountStrategy` where labeled parents shouldn't have the strategy applied to their children.
* Fixed a bug in `PathRetractionStrategy` where `MatchEndStep` labels were being dropped when they shouldn't be.
* Added `TinkerGraphCountStrategy` which translates `g.V().map*.count()` patterns into direct `Map.size()` calls in `TinkerGraph`.

directly.
Posted by sp...@apache.org.
Set TinkerIoRegistryV2 in cofig files directly.
This should have been this way when we added GraphSON 2.0 as the default for TinkerGraph is to still use GraphSON 1.0. CTR

* Fixed a OLAP `MatchStep.clone()`-bug that occurs when the `match()` is in a local child.
+* Added another optimization in `RangeByIsCountStrategy`, that removes `count().is()` altogether if it's not needed.
* Fixed a bug in `RangeByIsCountStrategy` where labeled parents shouldn't have the strategy applied to their children.
* Fixed a bug in `PathRetractionStrategy` where `MatchEndStep` labels were being dropped when they shouldn't be.
* Added `TinkerGraphCountStrategy` which translates `g.V().map*.count()` patterns into direct `Map.size()` calls in `TinkerGraph`.

fixed a bug in MatchStep that I forgot we had. Because of it, we had 3 tests commented out. Doh. The tests were a combination of problems in PathRetractionsStrategy and RangeByIsCountStratyegy. Because of the fix in PathRetractionStrategy, some match benchmarks got significantly faster.
