Implements server-side encryption capabilities (v0.13.0) including:
- Core Support: SSE-S3 (AES256) and SSE-KMS
- Integration: Added encryption fields to UploadInput, CopyObjectInput, InitiateMultipartUploadInput, and MultipartUploadInput
- Operations: Updated FilePut, FileUpload (POST), CopyObject, and multipart upload flows to support encryption headers
- API: Updated FileDetails (HeadObject) to return ServerSideEncryption and SSEKMSKeyId in DetailsResponse
Testing:
- Configured MinIO with built-in KMS (via MINIO_KMS_SECRET_KEY) in docker-compose.yml to enable SSE-S3 support
- Added comprehensive integration tests verifying headers are correctly sent and returned
- Verified file integrity and encryption status across all upload methods
Updated ROADMAP.md to mark v0.13.0 as completed.
"Verify the multipart upload implementation works correctly by running integration tests against MinIO and validating file integrity, parallel uploads, and error handling."
Core APIs:
- Add InitiateMultipartUpload for starting multipart uploads
- Add UploadPart for uploading individual parts (5MB-5GB)
- Add CompleteMultipartUpload to finalize uploads
- Add AbortMultipartUpload to cancel and cleanup uploads
- Add ListParts to query uploaded parts
High-Level Features:
- Add FileUploadMultipart API with automatic chunking
- Add uploadPartWithRetry with exponential backoff (3 retries default)
- Add parallel upload worker pool with configurable concurrency
- Add progress callbacks for real-time upload tracking
- Add GeneratePresignedUploadPartURL for browser-based uploads
Advanced Features:
- Automatic file chunking with configurable part sizes (5MB-5GB)
- Parallel upload worker pool with configurable concurrency
- Retry logic with exponential backoff (configurable retries)
- Real-time progress tracking with upload speed calculation
- Automatic cleanup on errors via AbortMultipartUpload
- Support for resumable uploads via ListParts
- Comprehensive input validation for all parameters
- File integrity verification across all upload modes
Testing:
- Add comprehensive integration tests (500+ lines)
- Test sequential uploads (15MB, 3 parts, ~45 MB/s)
- Test parallel uploads (20MB, 4 parts, concurrency=3)
- Test small files (3MB, single part)
- Validate abort and ListParts functionality
- Test input validation and error cases
- Verify file integrity with hash comparison
- All tests passing against MinIO
Documentation:
- Update README with multipart upload examples
- Add high-level and low-level API usage
- Document browser-based multipart uploads
- Mark multipart upload implementation as complete in ROADMAP
- Update gitignore to exclude *.bin and test-output.log
Verified against MinIO with complete test coverage.
