160-161: Add Javadoc documentation for the new method.The new
registerBizIfAbsentmethod lacks Javadoc documentation. Please add documentation following the interface's convention to describe:
- The method's purpose
- The
bizparameter- The return value semantics (when it returns true/false)
Consider this template:
+ /** + * Register Biz only if it's not already registered + * + * @param biz The business module to register + * @return true if the biz was registered, false if it already exists + */ boolean registerBizIfAbsent(Biz biz);
160-161: Consider reorganizing method placement.For better code organization and readability, consider moving this method next to the similar
registerBizmethod (around line 42), as they are functionally related.sofa-ark-parent/core-impl/container/src/main/java/com/alipay/sofa/ark/container/service/biz/BizManagerServiceImpl.java (1)
226-239: Document the thread-safety guarantees.The method implements thread-safe registration, but this behavior isn't documented. Consider adding Javadoc to clarify the concurrency guarantees.
Add documentation like this:
+ /** + * Thread-safe registration of a Biz instance if not already present. + * This method ensures that only one instance of a Biz with the same name and version + * can be registered, even under concurrent access. + * + * @param biz the Biz instance to register + * @return true if the Biz was registered, false if an instance was already present + * @throws IllegalArgumentException if biz is null or not in RESOLVED state + */ @Override public boolean registerBizIfAbsent(Biz biz) {sofa-ark-parent/core-impl/container/src/main/java/com/alipay/sofa/ark/container/pipeline/HandleArchiveStage.java (2)

160-161: LGTM on the method signature.
The method signature aligns well with the PR's objective of deduplicating module deployments and follows the interface's existing patterns.
Let's verify the implementation of this method:
✅ Verification successful
Let me gather more information about the implementation.
Implementation is thread-safe and correctly handles deduplication
The implementation is well-designed with proper thread safety using a combination of ConcurrentHashMap and synchronized block:
- Uses ConcurrentHashMap for the main bizRegistration storage
- Implements double-checked locking pattern for thread-safe registration
- Correctly uses putIfAbsent for the outer map and synchronized block for the inner map operations
- Properly validates input parameters before registration
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check the implementation to ensure thread-safety and proper deduplication logic
# Look for the implementation class

Line range hint 19-46: LGTM! Imports are appropriate for the new test implementation.
The new imports (ArkClient, Biz, MockedStatic) are necessary to support the static mocking strategy used in the updated test.
sofa-ark-parent/core-impl/container/src/main/java/com/alipay/sofa/ark/container/pipeline/HandleArchiveStage.java (1)
200-200: LGTM! Good improvement for deduplication.
The change from registerBiz to registerBizIfAbsent aligns well with the PR objective of deduplicating module deployments during static merge. This prevents potential issues with duplicate registrations while maintaining the existing functionality.
Let's verify the error handling in the new registration path:
✅ Verification successful
Error handling is properly implemented in registerBizIfAbsent
The implementation of registerBizIfAbsent in BizManagerServiceImpl has appropriate error handling:
- Input validation using
AssertUtilsto check for null and valid state - Thread-safe implementation using synchronization
- Proper state verification before registration
- Returns boolean to indicate success/failure
The change from registerBiz to registerBizIfAbsent is safe and well-implemented.

200-200: LGTM! Verify error handling in BizManagerService
The change from registerBiz to registerBizIfAbsent aligns with the PR objective of deduplicating module deployments. This is a good improvement to prevent duplicate registrations during static merge deployments.
Let's verify the error handling in the new method:
✅ Verification successful
LGTM! Error handling is properly implemented
The implementation of registerBizIfAbsent in BizManagerServiceImpl has robust error handling:
- Validates non-null biz parameter using
AssertUtils.assertNotNull - Verifies biz state using
AssertUtils.isTrue - Uses thread-safe concurrent collections and proper synchronization
- Implements proper duplicate checking with double-checked locking pattern
The change is safe and well-implemented across the codebase:
- Used consistently in both
ArkContainerandHandleArchiveStage - Maintains thread safety with
ConcurrentHashMap - Returns boolean to indicate registration status

Line range hint 196-202: Verify consistent registration behavior across all entry points
To ensure system-wide consistency, we should verify that all biz registration entry points use the same deduplication strategy.
✅ Verification successful
Let me analyze the registration behavior across the codebase based on the search results.
Registration behavior is consistent across entry points
After analyzing the implementation and usage patterns, I can confirm that the registration behavior is consistent across all entry points:
registerBizis used in test code and internal pipeline stages for direct registrationregisterBizIfAbsentis used in production code paths (ArkContainer, HandleArchiveStage) for safe concurrent registration- The
registerBizIfAbsentimplementation properly handles thread safety with double-checked locking pattern when adding new biz entries
The new code in ArkContainer correctly uses registerBizIfAbsent, which is the appropriate method for production registration paths.

Fix incorrect test data: Biz object is null
The test is verifying registerBizIfAbsent(null), which doesn't properly test the deduplication logic. The Biz object should be created from the mocked BizArchive.
Apply this diff to fix the test:

- verify(bizFactoryService, times(1)).createBiz((bizArchive));
- verify(bizManagerService, times(1)).registerBizIfAbsent(null);

🛠️ Refactor suggestion
Enhance test coverage for deduplication scenarios
The test should verify the actual deduplication behavior by testing scenarios where:
- A Biz doesn't exist (should register)
- A Biz already exists (should skip registration)

Thread safety concern in double-checked locking implementation.
The synchronized block locks on a ConcurrentHashMap value which could potentially be replaced by another thread, leading to synchronization issues. Consider using a more robust synchronization approach.
Here's a suggested implementation that addresses this concern:
@Override
public boolean registerBizIfAbsent(Biz biz) {
AssertUtils.assertNotNull(biz, "Biz must not be null.");
AssertUtils.isTrue(biz.getBizState() == BizState.RESOLVED, "BizState must be RESOLVED.");
- if (getBiz(biz.getBizName(), biz.getBizVersion()) == null) {
- bizRegistration.putIfAbsent(biz.getBizName(), new ConcurrentHashMap<>(16));
- synchronized (bizRegistration.get(biz.getBizName())) {
- if (getBiz(biz.getBizName(), biz.getBizVersion()) == null) {
- ConcurrentHashMap<String, Biz> bizCache = bizRegistration.get(biz.getBizName());
- return bizCache.put(biz.getBizVersion(), biz) == null;
- }
- }
+ String bizName = biz.getBizName();
+ String bizVersion = biz.getBizVersion();
+
+ // Create the version map if absent
+ bizRegistration.putIfAbsent(bizName, new ConcurrentHashMap<>(16));
+ ConcurrentHashMap<String, Biz> bizCache = bizRegistration.get(bizName);
+
+ // Use putIfAbsent for atomic check-then-act
+ return bizCache.putIfAbsent(bizVersion, biz) == null;
}
- return false;
}The suggested implementation:
- Eliminates the need for explicit synchronization by leveraging ConcurrentHashMap's atomic operations
- Reduces redundant getBiz calls
- Maintains thread safety while improving performance

💡 Codebase verification
Add concurrent test cases for registerBizIfAbsent method
The current test suite (BizManagerServiceTest.java) lacks concurrent testing for the registerBizIfAbsent method, while the codebase already has examples of concurrent testing patterns in ClassLoaderConcurrencyTest.java. Consider adding test cases that:
- Use multiple threads to register the same biz simultaneously
- Verify that only one registration succeeds
- Follow the concurrent testing pattern from
ClassLoaderConcurrencyTest.javausingCountDownLatchandThreadPoolExecutor
🔗 Analysis chain
Consider adding unit tests for concurrent scenarios.
The new method handles concurrent registration attempts, but there are no visible tests verifying this behavior.

- The method's purpose
- The parameter description
- The return value meaning (true if registered, false if already exists)
+ /** + * Register Biz only if it's not already registered + * + * @param biz The business entity to register + * @return true if the biz was registered, false if it already exists + */ boolean registerBizIfAbsent(Biz biz);
160-161: LGTM! The new method enhances deduplication.The addition of
registerBizIfAbsentis a good enhancement that supports the PR's objective of deduplicating module deployments during static merge deployments. It provides an atomic way to check-and-register business entities, preventing duplicate registrations.Consider implementing this method in a thread-safe manner in the implementation class, possibly using the
putIfAbsentoperation of theConcurrentHashMapthat's already used ingetBizRegistration().sofa-ark-parent/core-impl/container/src/main/java/com/alipay/sofa/ark/container/service/biz/BizManagerServiceImpl.java (1)
225-239: LGTM! Thread-safe implementation for deduplication.The implementation correctly handles concurrent registration attempts using double-checked locking pattern and maintains consistency with existing validation logic.
Consider optimizing the synchronization granularity by using a more specific lock object:
- synchronized (bizRegistration.get(biz.getBizName())) { + ConcurrentHashMap<String, Biz> bizCache = bizRegistration.get(biz.getBizName()); + synchronized (bizCache) { if (getBiz(biz.getBizName(), biz.getBizVersion()) == null) { - ConcurrentHashMap<String, Biz> bizCache = bizRegistration.get(biz.getBizName()); return bizCache.put(biz.getBizVersion(), biz) == null; } }This change:
- Reduces the number of map lookups
- Makes the synchronized block's scope more explicit
- Maintains the same thread-safety guarantees

199-201: Consider adding debug logging for skipped registrations.To aid in troubleshooting, consider logging when a biz registration is skipped due to an existing registration.
public void processStaticBizFromClasspath(PipelineContext pipelineContext) throws Exception { ExecutableArchive executableArchive = pipelineContext.getExecutableArchive(); List<BizArchive> bizArchives = executableArchive.getBizArchives(); for (BizArchive bizArchive : bizArchives) { Biz biz = bizFactoryService.createBiz(bizArchive); - bizManagerService.registerBizIfAbsent(biz); + if (!bizManagerService.registerBizIfAbsent(biz)) { + ArkLoggerFactory.getDefaultLogger().debug( + "Skipped registering duplicate biz: {}", biz.getIdentity()); + } } }sofa-ark-parent/core-impl/container/src/main/java/com/alipay/sofa/ark/container/ArkContainer.java (1)
Line range hint
156-173: Consider documenting the deployment order guaranteesThe deployment lifecycle involves multiple stages (master biz → static biz → custom hooks), and the new deduplication logic makes the order of deployment more significant. Consider documenting:
- The order guarantees between different deployment stages
- How version conflicts are resolved when the same biz is registered through different paths
Would you like me to help draft the documentation for the deployment lifecycle?

225-239: Verify integration with dependent components.
Let's confirm that all callers properly handle the return value of registerBizIfAbsent.
✅ Verification successful
Let me gather more context about error handling in the calling methods.
Integration with dependent components is properly implemented
The verification shows that registerBizIfAbsent is used correctly in all calling contexts:
- In
ArkContainer.addStaticBiz, the method is called within a proper error handling context (wrapped in a method that declaresthrows IOException) - In
HandleArchiveStage.processStaticBizFromClasspath, it's called within a method that declaresthrows Exception - The method's preconditions are enforced through
AssertUtilschecks - The return value (boolean) is appropriately used as a status indicator, not requiring explicit handling since a false return simply means the biz was already registered

200-200: LGTM! The change aligns with deduplication objectives.
The switch to registerBizIfAbsent effectively prevents duplicate module registrations during static merge deployments, which is the core objective of this PR.
Let's verify the thread safety and implementation of registerBizIfAbsent:
✅ Verification successful
Let me search for the implementation of registerBizIfAbsent to verify thread safety.
Let me check the implementation of registerBizIfAbsent in BizManagerServiceImpl.java to verify thread safety.
Thread-safe implementation confirmed, change is safe
The registerBizIfAbsent implementation in BizManagerServiceImpl is thread-safe:
- Uses
ConcurrentHashMapfor both levels of caching - Implements proper double-checked locking pattern with synchronized block
- Maintains consistent state checks and validations
The change from registerBiz to registerBizIfAbsent is a safe improvement that:
- Prevents duplicate registrations
- Maintains thread safety
- Preserves first-registered instance

200-200: LGTM! Verify thread safety and version handling
The change from registerBiz to registerBizIfAbsent aligns with the PR objective of deduplicating module deployments. This prevents duplicate registration while maintaining first-registered-wins semantics.
Let's verify the implementation of registerBizIfAbsent and its thread safety:
✅ Verification successful
Based on the shell script results, I can now verify the thread safety and version handling in the registerBizIfAbsent implementation:
-
The implementation in
BizManagerServiceImpluses proper synchronization:- Uses
ConcurrentHashMapfor the bizRegistration map - Has synchronized block on the biz name's map for atomic check-then-act
- Performs version check via
getBizbefore registration
- Uses
-
The version handling is robust:
- Checks for existing biz with same name and version before registration
- Uses two-level concurrent map structure for name->version->biz mapping
- Maintains proper state validation (RESOLVED state check)
-
The change is used consistently:
- Only used in static biz deployment scenarios
- Other registration paths still use
registerBizfor strict control
The implementation is thread-safe and handles versioning correctly
The change from registerBiz to registerBizIfAbsent is properly implemented with thread-safe concurrent collections and synchronized blocks. The version handling ensures no duplicate registrations of the same biz version.

Test implementation needs improvement
Several issues need to be addressed:
- The verification
registerBizIfAbsent(null)on line 173 appears incorrect as we're creating a biz archive and factory but not verifying the actual biz object. - The test doesn't verify the deduplication behavior which is the main objective of this PR.
- Missing verification of manifest attributes usage.
Consider refactoring the test like this:
@Test
public void testProcessStaticBizFromClasspath() throws Exception {
MockedStatic<ArkClient> arkClientMockedStatic = mockStatic(ArkClient.class);
arkClientMockedStatic.when(ArkClient::getBizManagerService).thenReturn(bizManagerService);
try {
BizArchive bizArchive = mock(BizArchive.class);
Manifest manifest = new Manifest();
Attributes mainAttributes = manifest.getMainAttributes();
mainAttributes.putValue(ARK_BIZ_NAME, "biz1");
mainAttributes.putValue(ARK_BIZ_VERSION, "0.0.1");
when(bizArchive.getManifest()).thenReturn(manifest);
ConcurrentHashMap<String, ConcurrentHashMap<String, Biz>> map = new ConcurrentHashMap<>();
when(bizManagerService.getBizRegistration()).thenReturn(map);
when(executableArchive.getBizArchives()).thenReturn(asList(bizArchive));
+ // Create and configure mock Biz
+ Biz mockBiz = mock(Biz.class);
+ when(mockBiz.getBizName()).thenReturn("biz1");
+ when(mockBiz.getBizVersion()).thenReturn("0.0.1");
+ when(bizFactoryService.createBiz(bizArchive)).thenReturn(mockBiz);
handleArchiveStage.processStaticBizFromClasspath(pipelineContext);
- verify(bizFactoryService, times(1)).createBiz((bizArchive));
- verify(bizManagerService, times(1)).registerBizIfAbsent(null);
+ verify(bizFactoryService, times(1)).createBiz(bizArchive);
+ verify(bizManagerService, times(1)).registerBizIfAbsent(mockBiz);
+
+ // Test deduplication
+ handleArchiveStage.processStaticBizFromClasspath(pipelineContext);
+ // Should still be called only once total
+ verify(bizManagerService, times(1)).registerBizIfAbsent(mockBiz);
}finally {
arkClientMockedStatic.close();
}
}This refactored version:
- Properly creates and verifies a mock Biz object
- Tests the deduplication behavior by calling the method twice
- Verifies that registration happens only once

226-232: LGTM! Thread-safe implementation for conditional registration.
The implementation correctly uses ConcurrentHashMap's atomic operations to ensure thread safety without explicit synchronization. The use of putIfAbsent instead of put properly handles the deduplication requirement.
