00:00:00 2001 From: Simon Schrottner Date: Tue, 26 Aug 2025 10:38:06 +0200 Subject: [PATCH 03/32] feat: Create OpenFeature SDK module with ServiceLoader provider MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Implement DefaultOpenFeatureAPI extending abstract API class - Add ServiceLoader provider registration for automatic discovery - Create META-INF/services configuration for SDK implementation - Move existing implementation to SDK module structure - Update imports to use API module for core interfaces - Register DefaultOpenFeatureAPIProvider with priority 0 Key components: - DefaultOpenFeatureAPI: Full SDK implementation extending API abstract class - DefaultOpenFeatureAPIProvider: ServiceLoader provider with standard priority - META-INF/services: Registration file for automatic discovery - NoOpProvider, NoOpTransactionContextPropagator: SDK utility classes (distinct from API fallbacks) Note: Import migration partially complete - some compilation errors remain Architecture is sound but needs additional import cleanup to fully compile 🤖 Generated with [Claude Code](https://claude.ai/code)

e890a198ae9ae5e8d2911140efd92c06902819eb Mon Sep 17 00:00:00 2001 From: Simon Schrottner Date: Tue, 26 Aug 2025 10:57:43 +0200 Subject: [PATCH 04/32] feat: Complete OpenFeature API module with interface segregation and ServiceLoader MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit establishes a stable, production-ready API module that separates core OpenFeature contracts from SDK implementation details: ## Core Features - **ServiceLoader Pattern**: Automatic implementation discovery with priority-based selection - **Interface Segregation**: Clean separation via OpenFeatureCore, OpenFeatureHooks, OpenFeatureContext, and OpenFeatureEventHandling interfaces - **No-op Fallback**: Safe default implementation for API-only consumers - **Backward Compatibility**: Existing user code continues to work seamlessly ## Architecture - **openfeature-api**: Minimal module with core contracts, interfaces, and data types - **Abstract OpenFeatureAPI**: ServiceLoader singleton that combines all interfaces - **NoOpOpenFeatureAPI**: Safe fallback when no SDK implementation is available - **Clean Dependencies**: Only essential dependencies (slf4j, lombok, spotbugs) ## Key Components - Core interfaces and data structures (Client, FeatureProvider, Value, Structure, etc.) - Exception hierarchy with proper error codes - Event handling contracts for advanced SDK functionality - Double-checked locking singleton pattern for thread-safe initialization The API module compiles successfully and passes all tests, providing a stable foundation for multiple SDK implementations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner Signed-off-by: Simon Schrottner ---

charset=UTF-8 Content-Transfer-Encoding: 8bit Moved implementation-specific internal utilities from the API module to the SDK module to create a cleaner API contract: ## Moved Classes - **AutoCloseableLock** & **AutoCloseableReentrantReadWriteLock**: Thread-safe locking utilities used by SDK implementation - **ObjectUtils**: Collection merging and null-handling utilities for SDK operations - **TriConsumer**: Functional interface used by SDK event handling system ## Kept in API - **ExcludeFromGeneratedCoverageReport**: Testing annotation that API implementations may use ## Benefits - **Cleaner API**: API module now contains only essential contracts and interfaces - **Better Separation**: Implementation utilities properly isolated in SDK module - **Reduced Dependencies**: API consumers don't get unnecessary internal utilities - **Maintained Functionality**: All SDK features continue to work with updated imports Both API and SDK modules compile and test successfully after the refactoring. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner Signed-off-by: Simon Schrottner --- .../main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java | 4 ++-- .../src/main/java/dev/openfeature/sdk/EventProvider.java | 2 +- .../src/main/java/dev/openfeature/sdk/OpenFeatureClient.java | 2 +- .../java/dev/openfeature/sdk}/internal/AutoCloseableLock.java | 2 +- .../sdk}/internal/AutoCloseableReentrantReadWriteLock.java | 2 +- .../main/java/dev/openfeature/sdk}/internal/ObjectUtils.java | 2 +- .../main/java/dev/openfeature/sdk}/internal/TriConsumer.java | 2 +- 7 files changed, 8 insertions(+), 8 deletions(-) rename {openfeature-api/src/main/java/dev/openfeature/api => openfeature-sdk/src/main/java/dev/openfeature/sdk}/internal/AutoCloseableLock.java (84%) rename {openfeature-api/src/main/java/dev/openfeature/api => openfeature-sdk/src/main/java/dev/openfeature/sdk}/internal/AutoCloseableReentrantReadWriteLock.java (95%) rename {openfeature-api/src/main/java/dev/openfeature/api => openfeature-sdk/src/main/java/dev/openfeature/sdk}/internal/ObjectUtils.java (98%) rename {openfeature-api/src/main/java/dev/openfeature/api => openfeature-sdk/src/main/java/dev/openfeature/sdk}/internal/TriConsumer.java (96%) diff --git a/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java b/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java index 28445e072..3fd8e89d1 100644 --- a/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java +++ b/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java @@ -11,8 +11,8 @@ import dev.openfeature.api.ProviderEventDetails;

module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove all Lombok annotations and imports from 28 API files - Replace with manual implementations: - equals(), hashCode(), toString() methods using Objects utility - Manual builders with fluent API following builder pattern - Manual getters/setters for data classes - Manual constructors and delegation patterns - Manual loggers replacing @Slf4j - Fix 45 checkstyle violations (braces, Javadoc, method ordering) - Add defensive copying in EventDetailsBuilder to prevent SpotBugs violations - API module now compiles without Lombok dependency - All 80 tests pass with full verification (checkstyle, spotbugs, coverage) - Maintain full backward compatibility of public API - Move lombok.config to SDK module for continued Lombok usage there 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner Signed-off-by: Simon Schrottner ---

charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove all Lombok annotations and imports from 11 SDK source files - Replace with manual implementations: - Manual loggers replacing @Slf4j in all SDK classes - Manual Flag class with builder pattern, getters, equals/hashCode/toString - Manual getters replacing @Getter annotations - Remove @SneakyThrows and add proper exception handling - Convert ObjectUtils from @UtilityClass to standard utility class - Remove Lombok dependency from openfeature-sdk/pom.xml - Update module-info.java to remove "requires static lombok" - Fix compilation issue with EventDetails.builder() -> EventDetails.eventDetailsBuilder() - Main SDK source compilation now works without Lombok - All core functionality maintains same public API - Test files with Lombok annotations to be addressed separately Both API and SDK modules are now Lombok-free for main source code. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner Signed-off-by: Simon Schrottner --- openfeature-sdk/lombok.config | 2 - openfeature-sdk/pom.xml | 10 +- .../sdk/DefaultOpenFeatureAPI.java | 7 +- .../dev/openfeature/sdk/EventProvider.java | 5 +- .../dev/openfeature/sdk/EventSupport.java | 5 +- .../sdk/FeatureProviderStateManager.java | 5 +- .../java/dev/openfeature/sdk/HookSupport.java | 7 +- .../openfeature/sdk/OpenFeatureClient.java | 18 +-- .../openfeature/sdk/ProviderRepository.java | 5 +- .../sdk/hooks/logging/LoggingHook.java | 5 +- .../openfeature/sdk/internal/ObjectUtils.java | 11 +- .../sdk/providers/memory/Flag.java | 113 ++++++++++++++++-- .../providers/memory/InMemoryProvider.java | 28 +++-- .../src/main/java/module-info.java | 5 +- .../openfeature/sdk/OpenFeatureAPITest.java | 1 - 15 files changed, 163 insertions(+), 64 deletions(-) delete mode 100644 openfeature-sdk/lombok.config diff --git a/openfeature-sdk/lombok.config b/openfeature-sdk/lombok.config deleted file mode 100644 index ec3b05682..000000000 --- a/openfeature-sdk/lombok.config +++ /dev/null @@ -1,2 +0,0 @@ -lombok.addLombokGeneratedAnnotation = true -lombok.extern.findbugs.addSuppressFBWarnings = true diff --git a/openfeature-sdk/pom.xml b/openfeature-sdk/pom.xml index 3fa10b5cd..c6b541139 100644 --- a/openfeature-sdk/pom.xml +++ b/openfeature-sdk/pom.xml @@ -27,14 +27,6 @@ openfeature-api - - - org.projectlombok - lombok - 1.18.38 - provided - - com.github.spotbugs @@ -43,7 +35,7 @@ provided - + org.slf4j slf4j-api diff --git a/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java b/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java index 37b1ccca2..8f7be26e1 100644 --- a/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java +++ b/openfeature-sdk/src/main/java/dev/openfeature/sdk/DefaultOpenFeatureAPI.java @@ -24,16 +24,17 @@ import java.util.concurrent.ConcurrentLinkedQueue;

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Legacy File Cleanup - Remove entire legacy `src/` directory (85+ source files, 100+ test files) - Remove `pom.xml.backup` backup file - Remove orphaned `test_noop_access.java` test file - Cleanup eliminates duplicate code after successful module separation ## SDK Test Lombok Removal (17 files) ### Files with @Getter annotations: - MockHook.java: Added manual getters (isBeforeCalled, isAfterCalled, etc.) - ContextStoringProvider.java: Added manual getEvaluationContext() getter ### Files with @SneakyThrows annotations: - Replaced with proper `throws Exception` declarations in 12 test files: EventProviderTest, TrackingSpecTest, FlagEvaluationSpecTest, EventsTest, FeatureProviderStateManagerTest, HookSpecTest, LoggingHookTest, InMemoryProviderTest, StepDefinitions, TestEventsProvider, ThreadLocalTransactionContextPropagatorTest - DeveloperExperienceTest: Replaced with proper try-catch block ### Files with @UtilityClass annotations: - ProviderFixture.java, TestFlagsUtils.java, ConditionStubber.java: Replaced with private constructors to prevent instantiation ## Results - Project is now completely Lombok-free (both API and SDK modules) - Clean multi-module structure without legacy duplicates - All main source code compiles successfully - Maintains same test functionality with manual implementations 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner diff --git c/openfeature-sdk/src/test/java/dev/openfeature/sdk/DeveloperExperienceTest.java i/openfeature-sdk/src/test/java/dev/openfeature/sdk/DeveloperExperienceTest.java index 16bca51..fe45552 100644 --- c/openfeature-sdk/src/test/java/dev/openfeature/sdk/DeveloperExperienceTest.java +++ i/openfeature-sdk/src/test/java/dev/openfeature/sdk/DeveloperExperienceTest.java @@ -28,7 +28,6 @@ import java.util.HashMap;

charset=UTF-8 Content-Transfer-Encoding: 8bit Updated test classes to use the new immutable POJO design: ## Test Updates - **ProviderEvaluationTest**: Updated both `empty()` and `builderWithAllFields()` tests to use builder pattern - **FlagEvaluationDetailsTest**: Updated both `empty()` and `builderWithAllFields()` tests to use builder pattern - Applied Spotless formatting fixes for consistent code style ## Results - ✅ All 80 tests now passing - ✅ Checkstyle compliance maintained - ✅ SpotBugs issues resolved - ✅ Full verification pipeline passes The tests now properly demonstrate the intended usage pattern where POJOs can only be created through builders, enforcing immutability and consistency. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner Signed-off-by: Simon Schrottner --- .../api/FlagEvaluationDetails.java | 7 ------- .../openfeature/api/ProviderEvaluation.java | 6 ------ .../api/FlagEvaluationDetailsTest.java | 21 ++++++++++++------- .../api/ProviderEvaluationTest.java | 20 +++++++++++------- 4 files changed, 27 insertions(+), 27 deletions(-) diff --git a/openfeature-api/src/main/java/dev/openfeature/api/FlagEvaluationDetails.java b/openfeature-api/src/main/java/dev/openfeature/api/FlagEvaluationDetails.java index bbe594e9b..16fec9922 100644 --- a/openfeature-api/src/main/java/dev/openfeature/api/FlagEvaluationDetails.java +++ b/openfeature-api/src/main/java/dev/openfeature/api/FlagEvaluationDetails.java @@ -59,37 +59,30 @@ public String getFlagKey() { return flagKey;

+## 🚫 Removed Public APIs + +### Public Setters +**Breaking**: All public setters removed from immutable POJOs. + +**Removed Methods**: +- `ProviderEvaluation.setValue(T)` +- `ProviderEvaluation.setVariant(String)` +- `ProviderEvaluation.setReason(String)` +- `ProviderEvaluation.setErrorCode(ErrorCode)` +- `ProviderEvaluation.setErrorMessage(String)` +- `ProviderEvaluation.setFlagMetadata(ImmutableMetadata)` +- `FlagEvaluationDetails.setFlagKey(String)` +- `FlagEvaluationDetails.setValue(T)` +- `FlagEvaluationDetails.setVariant(String)` +- `FlagEvaluationDetails.setReason(String)` +- `FlagEvaluationDetails.setErrorCode(ErrorCode)` +- `FlagEvaluationDetails.setErrorMessage(String)` +- `FlagEvaluationDetails.setFlagMetadata(ImmutableMetadata)` + +**Migration**: Use builders to create objects with desired state instead of mutation. + +### Public Constructors +**Breaking**: Public constructors removed from POJOs. + +**Removed Constructors**: +- `ProviderEvaluation()` +- `ProviderEvaluation(T, String, String, ErrorCode, String, ImmutableMetadata)` +- `FlagEvaluationDetails()` +- `FlagEvaluationDetails(String, T, String, String, ErrorCode, String, ImmutableMetadata)` +- `EventDetails(String, String, ProviderEventDetails)` +- `ProviderEventDetails()` (deprecated, now private) +- `ProviderEventDetails(List, String, ImmutableMetadata, ErrorCode)` + +**Migration**: Use builder patterns exclusively for object creation. + +--- + +## 🔄 Migration Summary + +### For Library Authors (Feature Flag Provider Implementers) +1. **Update Dependencies**: Change from old `sdk` to new `api` module + ```xml + + + dev.openfeature + sdk + 1.17.0 + + + + + dev.openfeature + api + 2.0.0 + + ``` +2. **Review Package Access**: Ensure no usage of moved internal classes +3. **Update Documentation**: Reference new module structure +4. **Verify Scope**: API module contains only interfaces and POJOs needed for provider implementation + +### For SDK Users (Application Developers) +1. **Update Dependencies**: Update `sdk` dependency (same artifactId, new structure) + ```xml + + + dev.openfeature + sdk + 1.17.0 + + + + + dev.openfeature + sdk + 2.0.0 + + ``` +2. **Replace Constructors**: Use builders for all POJO creation +3. **Remove Setter Usage**: Objects are now immutable +4. **Update Convenience Methods**: Use builders instead of `from()` methods +5. **Ensure Provider Names**: Always specify provider names in events + +### For Build Systems & CI/CD +1. **Multi-module Builds**: Update build scripts to handle Maven multi-module structure +2. **Artifact Publishing**: Both API and SDK modules are now published separately +3. **Version Management**: Parent POM manages versions for both modules +4. **Testing**: Tests are distributed across both modules + +### Quick Migration Checklist + +#### Maven/Gradle Dependencies +- [ ] **Library Authors**: Update from `dev.openfeature:sdk` → `dev.openfeature:api` +- [ ] **App Developers**: Keep `dev.openfeature:sdk` but update version to `2.0.0` +- [ ] Update `groupId` (remains `dev.openfeature`) +- [ ] Update version to `2.0.0` +- [ ] Note: Parent POM is now `dev.openfeature:openfeature-java` + +#### Build System Changes +- [ ] Update CI/CD scripts for multi-module Maven structure +- [ ] Verify artifact publishing handles both API and SDK modules +- [ ] Update documentation references to new artifact names + +#### Code Changes +- [ ] Replace `new ProviderEvaluation<>()` with `ProviderEvaluation.builder().build()` +- [ ] Replace `new FlagEvaluationDetails<>()` with `FlagEvaluationDetails.builder().build()` +- [ ] Replace `new EventDetails()` with `EventDetails.builder().build()` +- [ ] Remove all setter method calls on POJOs +- [ ] Replace convenience methods with builder patterns +- [ ] Add provider names to all EventDetails creation +- [ ] Update any explicit builder type references + +## 💡 Benefits of These Changes + +### Thread Safety +- All POJOs are now immutable and thread-safe by default +- No risk of concurrent modification + +### API Consistency +- Unified builder patterns across all POJOs +- Predictable object creation patterns +- Clear separation between API contracts and implementation + +### OpenFeature Compliance +- Event details architecture now complies with OpenFeature specification +- Required fields are enforced at build time + +### Module Separation & Dependency Management +- **Clean Architecture**: Clear separation between API contracts (`openfeature-api`) and SDK implementation (`openfeature-sdk`) +- **Smaller Dependencies**: Library authors can depend on API-only module (lighter footprint) +- **Better Dependency Management**: Applications can choose between API-only or full SDK +- **Multi-module Maven Structure**: Better organization and build management +- **Independent Versioning**: Modules can evolve independently (though currently versioned together) + +### Build & Deployment Benefits +- **Parallel Builds**: Maven can build modules in parallel +- **Selective Deployment**: Can deploy API and SDK modules independently +- **Better Testing**: Test isolation between API contracts and implementation +- **Cleaner Artifacts**: API module contains only interfaces, POJOs, and exceptions + +--- + +**Note**: This is a major version release (v2.0.0) due to the breaking nature of these changes. All changes improve API consistency, thread safety, and OpenFeature specification compliance while maintaining the same core functionality. \ No newline at end of file diff --git a/openfeature-api/pom.xml b/openfeature-api/pom.xml index 6a0e16033..650ec8c34 100644 --- a/openfeature-api/pom.xml +++ b/openfeature-api/pom.xml @@ -10,7 +10,7 @@ 2.0.0 - openfeature-api + api OpenFeature Java API OpenFeature Java API - Core contracts and interfaces for feature flag evaluation diff --git a/openfeature-sdk/src/test/java/dev/openfeature/sdk/TelemetryTest.java b/openfeature-api/src/test/java/dev/openfeature/api/TelemetryTest.java similarity index 80% rename from openfeature-sdk/src/test/java/dev/openfeature/sdk/TelemetryTest.java rename to openfeature-api/src/test/java/dev/openfeature/api/TelemetryTest.java index 7fb4f1726..851a1446f 100644 --- a/openfeature-sdk/src/test/java/dev/openfeature/sdk/TelemetryTest.java +++ b/openfeature-api/src/test/java/dev/openfeature/api/TelemetryTest.java @@ -1,22 +1,10 @@ -package dev.openfeature.sdk;

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Value.objectToValue() Enhancement - Add support for Long and Float types in objectToValue() method - Long and Float now use generic Value(Object) constructor with proper exception handling - Maintains same exception handling approach as other numeric types ## ImmutableMetadata Builder Consistency - Remove unnecessary try-catch blocks from addLong() and addFloat() methods - Both methods now use Value.objectToValue() consistently with other add methods - Eliminates redundant exception wrapping that was inconsistent with addInteger/addDouble - All builder methods now follow the same pattern ## Technical Details - Long and Float are Number subtypes, so Value(Object) constructor accepts them - The isNumber() check validates them as valid numeric types - No functional changes - same behavior with cleaner, consistent code ## Results - All 319 tests passing ✅ - Consistent exception handling across all ImmutableMetadata add methods - Cleaner code without unnecessary try-catch blocks - Better API consistency for developers This resolves the inconsistency where some builder methods used try-catch blocks while others used Value.objectToValue() directly. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude Signed-off-by: Simon Schrottner --- .../java/dev/openfeature/api/ImmutableMetadata.java | 12 ++---------- .../src/main/java/dev/openfeature/api/Value.java | 12 ++++++++++++ 2 files changed, 14 insertions(+), 10 deletions(-) diff --git a/openfeature-api/src/main/java/dev/openfeature/api/ImmutableMetadata.java b/openfeature-api/src/main/java/dev/openfeature/api/ImmutableMetadata.java index d597f6ade..16e36a024 100644 --- a/openfeature-api/src/main/java/dev/openfeature/api/ImmutableMetadata.java +++ b/openfeature-api/src/main/java/dev/openfeature/api/ImmutableMetadata.java @@ -221,11 +221,7 @@ public Builder addInteger(final String key, final Integer value) { * @param value flag metadata value to add */ public Builder addLong(final String key, final Long value) { - try { - attributes.put(key, new Value(value));

Quick Migration Guide

+ * + *

1. Update Dependencies

+ * 
{@code
+ * 
+ * 
+ *     dev.openfeature
+ *     sdk
+ *     2.0.0
+ * 
+ * }
+ * + *

2. Replace Setters with Builders

+ * 
{@code
+ * // BEFORE (will throw UnsupportedOperationException)
+ * ProviderEvaluation eval = new ProviderEvaluation<>();
+ * eval.setValue("test");
+ *
+ * // AFTER (works in v2.0)
+ * ProviderEvaluation eval = ProviderEvaluation.builder()
+ *     .value("test")
+ *     .build();
+ * }
+ * + *

3. Update Imports (Gradual)

+ * 
{@code
+ * // BEFORE (deprecated in v2.0)
+ * import dev.openfeature.sdk.FeatureProvider;
+ * import dev.openfeature.sdk.Features;
+ *
+ * // AFTER (recommended in v2.0+)
+ * import dev.openfeature.api.Provider;
+ * import dev.openfeature.api.evaluation.EvaluationClient;
+ * }
+ * + *

4. Update Interface Names

+ * 
{@code
+ * // BEFORE
+ * public class MyProvider implements FeatureProvider { }
+ * Features client = OpenFeature.getClient();
+ *
+ * // AFTER
+ * public class MyProvider implements Provider { }
+ * EvaluationClient client = OpenFeature.getClient();
+ * }
+ * + *

What Works Immediately

+ *
    + *
  • ✅ Interface implementations (with deprecation warnings)
    • + *
  • ✅ Enum and constant usage
    • + *
  • ✅ Exception throwing and catching
    • + *
  • ✅ Object construction with builders
    • + *
  • ✅ Immutable object creation
    • + *
+ * + *

What Requires Changes

+ *
    + *
  • ❌ Setter method usage (throws UnsupportedOperationException)
    • + *
  • ❌ Mutable object patterns
    • + *
+ * + *

Timeline

+ *
    + *
  • v2.0.0: Compatibility layer available, deprecation warnings
    • + *
  • v2.1.0: Compatibility layer removed, breaking changes
