vlingo/xoom-symbio

This system is a persistence layer built on the Vlingo Xoom framework, designed to manage object and state storage through a pluggable adapter architecture. It provides core abstractions for entries and states, supporting JSON serialization and metadata management, while also including a native build configuration for GraalVM. The system is supported by comprehensive tests covering in-memory and object store behaviors.

A new Java class, NativeBuildEntryPoint, has been added to the nativebuild package. This class provides a C entry point for GraalVM native image builds, initializing the Vlingo Xoom World and configuring state stores for native execution.

src/main/java/nativebuild · medium confidence

Added new core classes for the Symbio persistence layer, including the \Entry\ and \State\ interfaces and their respective adapter interfaces (\EntryAdapter\, \StateAdapter\) to handle serialization between native objects and raw storage formats. The update introduces \BaseEntry\ and \State\ implementations (such as \TextEntry\, \ObjectEntry\, \BinaryState\) and default adapters (\DefaultTextEntryAdapter\, \DefaultTextStateAdapter\) that use JSON serialization. Additionally, \EntryAdapterProvider\ and \StateAdapterProvider\ are added to manage adapter registration and lookup within the Xoom World, while \Metadata\ is updated to support property maps alongside the legacy object-based approach.

src/main/java/io · high confidence

Added new test files to verify the behavior of the Symbio store components, including Metadata, State, and various store actors (in-memory, object, and state stores). The tests cover appending and reading events, persisting and querying objects, and handling gaps in the reader actor.

src/test · high confidence

The project's Maven build file (pom.xml) has been updated to use version 1.11.2-SNAPSHOT for the core vlingo XOOM dependencies, including xoom-common, xoom-actors, and xoom-streams. Additionally, the test dependency for JUnit has been upgraded to version 4.13.2, and Logback has been updated to 1.3.12.
