Fix Flaky .Net and server tests (#3431)

* Fix flaky transaction integration tests

shouldTrackTransactionCountAccurately was racing because commitTx()
and rollbackTx() returned without consuming the HTTP response. With
chunked transfer encoding, the client can receive response headers
before the server completes transactionManager.destroy(). Wrapping
in try-with-resources ensures the full response is read, guaranteeing
server-side processing is complete before asserting the count.

shouldTimeoutIdleTransactionWithNoOperations used a 1ms timeout,
which could expire during the beginTx() HTTP round-trip itself,
causing getFirstHeader(TRANSACTION_ID) to return null and NPE.
Increased to 500ms — still well below the 1000ms sleep that
validates timeout behavior.

* Serialize .NET integration tests that share the Gremlin Server graph

PropertyDeserializationTests and GraphTraversalTests were running
concurrently with @GraphComputerOnly Gherkin scenarios. During OLAP
computation, TinkerGraphComputer sets a graphComputerView on the
shared TinkerGraph instance. Any concurrent read through TinkerVertex
sees compute properties (like haltedTraversers) merged with real
properties, causing spurious assertion failures and NPEs.

Place all tests that hit the shared server into a single non-parallel
xUnit collection (GremlinServerTests) so they never overlap with an
active GraphComputer view.

TinkerPop3

Apache TinkerPop™ is a graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP). It provides the Gremlin graph traversal language, drivers, and tools for working with property graphs across a wide variety of underlying data systems.

Project overview

TinkerPop defines a common interface and language (Gremlin) so that applications can work against many different graph systems without being locked into a single vendor. It includes a reference in‑memory graph database (TinkerGraph), Gremlin Server, language variants, and a rich collection of recipes and documentation.

Key resources:

Building and Testing

TinkerPop uses Maven and requires Java 11/17 for proper building and proper operations. To build, execute unit tests and package Gremlin Console/Server run:

mvn clean install

Please see the Building on Windows section for Windows-specific build instructions.

The zip distributions can be found in the following directories:

  1. gremlin-server/target
  2. gremlin-console/target

Please see the CONTRIBUTING.md file for more detailed information and options for building, test running and developing TinkerPop.

Get Started

Download Gremlin Console (compatible with Java 11/17) and unzip to a directory, then:

$ bin/gremlin.sh

         \,,,/

From the Gremlin Console, you can connect to a TinkerGraph instance and run your first traversals. Refer to the Getting Started for detailed walkthroughs and examples.

Using TinkerPop

Common ways to use TinkerPop include:

  • Embedding TinkerGraph in your application for development, testing, or lightweight graph workloads.
  • Connecting to a Gremlin‑enabled graph database via drivers or Gremlin Server.
  • Running Gremlin traversals from the JVM, or via Gremlin Language Variants (Python, .NET, JavaScript, Go, etc.).
  • Using the Gremlin Console for interactive exploration, debugging, and learning.

See the Reference Documentation for supported features, configuration options, and other details.

Documentation

The full TinkerPop documentation is published on the project website and is also maintained in this repository under docs/src/ as AsciiDoc “books.”

When changing or adding documentation, follow the existing AsciiDoc structure in docs/src/** and update the relevant index.asciidoc files so new content is included in the build.

Contributing

Contributions to Apache TinkerPop are welcome. The Developer Documentation and contributing guide describe how to set up a development environment, run tests, and submit changes.

Before opening a pull request, please:

  • Discuss larger changes on the appropriate Apache mailing list.
  • Ensure tests pass locally and, where appropriate, add new tests and documentation.
  • Update CHANGELOG.asciidoc and upgrade docs when behavior or public APIs change.

Using AI and IDE assistants

If you use AI coding agents or IDE assistants when working on TinkerPop, please consult AGENTS.md. That file summarizes:

  • Recommended build and test commands.
  • Code style and testing conventions.
  • “Do and don’t” guidance specific to automated tools.

AGENTS.md is a concise guide for tools and tool‑using contributors, while CONTRIBUTING.md and the Developer Documentation remain the canonical sources for project policies and processes.
