* Fix rebase errors and restore structured BucketMetadata API
Merge Conflict Fixes:
- Fixed merge conflicts in header.go (SSE-C and SSE-KMS headers)
- Fixed merge conflicts in s3api_errors.go (SSE-C and SSE-KMS error codes)
- Fixed merge conflicts in s3_sse_c.go (copy strategy constants)
- Fixed merge conflicts in s3api_object_handlers_copy.go (copy strategy usage)
API Restoration:
- Restored BucketMetadata struct with Tags, CORS, and Encryption fields
- Restored structured API functions: GetBucketMetadata, SetBucketMetadata, UpdateBucketMetadata
- Restored helper functions: UpdateBucketTags, UpdateBucketCORS, UpdateBucketEncryption
- Restored clear functions: ClearBucketTags, ClearBucketCORS, ClearBucketEncryption
Handler Updates:
- Updated GetBucketTaggingHandler to use GetBucketMetadata() directly
- Updated PutBucketTaggingHandler to use UpdateBucketTags()
- Updated DeleteBucketTaggingHandler to use ClearBucketTags()
- Updated CORS handlers to use UpdateBucketCORS() and ClearBucketCORS()
- Updated loadCORSFromBucketContent to use GetBucketMetadata()
Internal Function Updates:
- Updated getBucketMetadata() to return *BucketMetadata struct
- Updated setBucketMetadata() to accept *BucketMetadata struct
- Updated getBucketEncryptionMetadata() to use GetBucketMetadata()
- Updated setBucketEncryptionMetadata() to use SetBucketMetadata()
Benefits:
- Resolved all rebase conflicts while preserving both SSE-C and SSE-KMS functionality
- Maintained consistent structured API throughout the codebase
- Eliminated intermediate wrapper functions for cleaner code
- Proper error handling with better granularity
- All tests passing and build successful
The bucket metadata system now uses a unified, type-safe, structured API
that supports tags, CORS, and encryption configuration consistently.
* Fix updateEncryptionConfiguration for first-time bucket encryption setup
- Change getBucketEncryptionMetadata to getBucketMetadata to avoid failures when no encryption config exists
- Change setBucketEncryptionMetadata to setBucketMetadataWithEncryption for consistency
- This fixes the critical issue where bucket encryption configuration failed for buckets without existing encryption
Fixes: https://github.com/seaweedfs/seaweedfs/pull/7144#discussion_r2285669572
* Fix rebase conflicts and maintain structured BucketMetadata API
Resolved Conflicts:
- Fixed merge conflicts in s3api_bucket_config.go between structured API (HEAD) and old intermediate functions
- Kept modern structured API approach: UpdateBucketCORS, ClearBucketCORS, UpdateBucketEncryption
- Removed old intermediate functions: setBucketTags, deleteBucketTags, setBucketMetadataWithEncryption
API Consistency Maintained:
- updateCORSConfiguration: Uses UpdateBucketCORS() directly
- removeCORSConfiguration: Uses ClearBucketCORS() directly
- updateEncryptionConfiguration: Uses UpdateBucketEncryption() directly
- All structured API functions preserved: GetBucketMetadata, SetBucketMetadata, UpdateBucketMetadata
Benefits:
- Maintains clean separation between API layers
- Preserves atomic metadata updates with proper error handling
- Eliminates function indirection for better performance
- Consistent API usage pattern throughout codebase
- All tests passing and build successful
The bucket metadata system continues to use the unified, type-safe, structured API
that properly handles tags, CORS, and encryption configuration without any
intermediate wrapper functions.
* Fix complex rebase conflicts and maintain clean structured BucketMetadata API
Resolved Complex Conflicts:
- Fixed merge conflicts between modern structured API (HEAD) and mixed approach
- Removed duplicate function declarations that caused compilation errors
- Consistently chose structured API approach over intermediate functions
Fixed Functions:
- BucketMetadata struct: Maintained clean field alignment
- loadCORSFromBucketContent: Uses GetBucketMetadata() directly
- updateCORSConfiguration: Uses UpdateBucketCORS() directly
- removeCORSConfiguration: Uses ClearBucketCORS() directly
- getBucketMetadata: Returns *BucketMetadata struct consistently
- setBucketMetadata: Accepts *BucketMetadata struct consistently
Removed Duplicates:
- Eliminated duplicate GetBucketMetadata implementations
- Eliminated duplicate SetBucketMetadata implementations
- Eliminated duplicate UpdateBucketMetadata implementations
- Eliminated duplicate helper functions (UpdateBucketTags, etc.)
API Consistency Achieved:
- Single, unified BucketMetadata struct for all operations
- Atomic updates through UpdateBucketMetadata with function callbacks
- Type-safe operations with proper error handling
- No intermediate wrapper functions cluttering the API
Benefits:
- Clean, maintainable codebase with no function duplication
- Consistent structured API usage throughout all bucket operations
- Proper error handling and type safety
- Build successful and all tests passing
The bucket metadata system now has a completely clean, structured API
without any conflicts, duplicates, or inconsistencies.
* Update remaining functions to use new structured BucketMetadata APIs directly
Updated functions to follow the pattern established in bucket config:
- getEncryptionConfiguration() -> Uses GetBucketMetadata() directly
- removeEncryptionConfiguration() -> Uses ClearBucketEncryption() directly
Benefits:
- Consistent API usage pattern across all bucket metadata operations
- Simpler, more readable code that leverages the structured API
- Eliminates calls to intermediate legacy functions
- Better error handling and logging consistency
- All tests pass with improved functionality
This completes the transition to using the new structured BucketMetadata API
throughout the entire bucket configuration and encryption subsystem.
* Fix GitHub PR #7144 code review comments
Address all code review comments from Gemini Code Assist bot:
1. **High Priority - SSE-KMS Key Validation**: Fixed ValidateSSEKMSKey to allow empty KMS key ID
- Empty key ID now indicates use of default KMS key (consistent with AWS behavior)
- Updated ParseSSEKMSHeaders to call validation after parsing
- Enhanced isValidKMSKeyID to reject keys with spaces and invalid characters
2. **Medium Priority - KMS Registry Error Handling**: Improved error collection in CloseAll
- Now collects all provider close errors instead of only returning the last one
- Uses proper error formatting with %w verb for error wrapping
- Returns single error for one failure, combined message for multiple failures
3. **Medium Priority - Local KMS Aliases Consistency**: Fixed alias handling in CreateKey
- Now updates the aliases slice in-place to maintain consistency
- Ensures both p.keys map and key.Aliases slice use the same prefixed format
All changes maintain backward compatibility and improve error handling robustness.
Tests updated and passing for all scenarios including edge cases.
* Use errors.Join for KMS registry error handling
Replace manual string building with the more idiomatic errors.Join function:
- Removed manual error message concatenation with strings.Builder
- Simplified error handling logic by using errors.Join(allErrors...)
- Removed unnecessary string import
- Added errors import for errors.Join
This approach is cleaner, more idiomatic, and automatically handles:
- Returning nil for empty error slice
- Returning single error for one-element slice
- Properly formatting multiple errors with newlines
The errors.Join function was introduced in Go 1.20 and is the
recommended way to combine multiple errors.
* Update registry.go
* Fix GitHub PR #7144 latest review comments
Address all new code review comments from Gemini Code Assist bot:
1. **High Priority - SSE-KMS Detection Logic**: Tightened IsSSEKMSEncrypted function
- Now relies only on the canonical x-amz-server-side-encryption header
- Removed redundant check for x-amz-encrypted-data-key metadata
- Prevents misinterpretation of objects with inconsistent metadata state
- Updated test case to reflect correct behavior (encrypted data key only = false)
2. **Medium Priority - UUID Validation**: Enhanced KMS key ID validation
- Replaced simplistic length/hyphen count check with proper regex validation
- Added regexp import for robust UUID format checking
- Regex pattern: ^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}$
- Prevents invalid formats like '------------------------------------' from passing
3. **Medium Priority - Alias Mutation Fix**: Avoided input slice modification
- Changed CreateKey to not mutate the input aliases slice in-place
- Uses local variable for modified alias to prevent side effects
- Maintains backward compatibility while being safer for callers
All changes improve code robustness and follow AWS S3 standards more closely.
Tests updated and passing for all scenarios including edge cases.
* Fix failing SSE tests
Address two failing test cases:
1. **TestSSEHeaderConflicts**: Fixed SSE-C and SSE-KMS mutual exclusion
- Modified IsSSECRequest to return false if SSE-KMS headers are present
- Modified IsSSEKMSRequest to return false if SSE-C headers are present
- This prevents both detection functions from returning true simultaneously
- Aligns with AWS S3 behavior where SSE-C and SSE-KMS are mutually exclusive
2. **TestBucketEncryptionEdgeCases**: Fixed XML namespace validation
- Added namespace validation in encryptionConfigFromXMLBytes function
- Now rejects XML with invalid namespaces (only allows empty or AWS standard namespace)
- Validates XMLName.Space to ensure proper XML structure
- Prevents acceptance of malformed XML with incorrect namespaces
Both fixes improve compliance with AWS S3 standards and prevent invalid
configurations from being accepted. All SSE and bucket encryption tests
now pass successfully.
* Fix GitHub PR #7144 latest review comments
Address two new code review comments from Gemini Code Assist bot:
1. **High Priority - Race Condition in UpdateBucketMetadata**: Fixed thread safety issue
- Added per-bucket locking mechanism to prevent race conditions
- Introduced bucketMetadataLocks map with RWMutex for each bucket
- Added getBucketMetadataLock helper with double-checked locking pattern
- UpdateBucketMetadata now uses bucket-specific locks to serialize metadata updates
- Prevents last-writer-wins scenarios when concurrent requests update different metadata parts
2. **Medium Priority - KMS Key ARN Validation**: Improved robustness of ARN validation
- Enhanced isValidKMSKeyID function to strictly validate ARN structure
- Changed from 'len(parts) >= 6' to 'len(parts) != 6' for exact part count
- Added proper resource validation for key/ and alias/ prefixes
- Prevents malformed ARNs with incorrect structure from being accepted
- Now validates: arn:aws:kms:region:account:key/keyid or arn:aws:kms:region:account:alias/aliasname
Both fixes improve system reliability and prevent edge cases that could cause
data corruption or security issues. All existing tests continue to pass.
