Implements ACL and Lifecycle management capabilities (v0.16.0) including:
- Bucket APIs: PutBucketAcl, GetBucketAcl, PutBucketLifecycle, GetBucketLifecycle, DeleteBucketLifecycle
- Object APIs: PutObjectAcl, GetObjectAcl
- Integration: Support for Canned ACLs (private, public-read, etc.) and Full Access Control Policies
- Lifecycle Configuration: Rules, Filters, Expiration, Transitions
Verified integration with MinIO:
- Note: MinIO returns 501 Not Implemented for Canned ACLs via headers, so tests for those are skipped while Custom ACLs (XML) are fully verified.
Includes comprehensive integration tests covering all operations.
Updated ROADMAP.md to mark v0.16.0 as completed.
Implements object versioning capabilities (v0.15.0) including:
- Bucket APIs: PutBucketVersioning, GetBucketVersioning
- Object Listing: ListVersions (lists versions and delete markers)
- Object Operations: Updated FileDownload, FileDelete, and FileDetails to support VersionId
- Integration tests covering the full versioning workflow (enable, upload versions, list, download specific version, delete specific version)
Documentation updated in README.md and ROADMAP.md.
"I have implemented Object Versioning (v0.15.0) as per the roadmap."
Implements object tagging capabilities (v0.14.0) including:
- Core APIs: PutObjectTagging, GetObjectTagging, DeleteObjectTagging
- Integration with FilePut, FileUpload, and CopyObject operations
- Helper functions for URL-encoded tag header formatting
- Comprehensive input validation (max 10 tags, required fields)
Addresses specific compatibility issues with MinIO and Cloudflare R2:
- Implements a 2-step workaround for CopyObject (copy first, then tag) to avoid SignatureDoesNotMatch errors caused by the x-amz-tagging-directive header on non-AWS providers.
Includes comprehensive integration tests and documentation updates.
"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.
Implements object manipulation capabilities for v0.11.0:
- CopyObject: server-side copy within/across buckets with metadata control
- DeleteObjects: batch delete up to 1000 objects in single request
Both operations follow AWS S3 API specification with proper:
- AWS Signature V4 signing
- XML request/response handling
- Content-MD5 and SHA256 headers
- Comprehensive input validation
Fixed DeleteObjects signature mismatch with MinIO by correcting the canonical
query string format for empty query parameter values (delete= instead of delete).
The writeQuery function now properly appends = to keys with empty values per
AWS Signature V4 specification.
CopyObject enables CLI mv commands. DeleteObjects enables efficient
batch operations for CLI sync/rm.
Tests: All CopyObject and DeleteObjects tests passing with MinIO.
"lets work on the object level operations"
Adds bucket management capabilities:
- ListBuckets: list all buckets for AWS account with owner info
- CreateBucket: create bucket with optional region support
- DeleteBucket: delete empty buckets
Includes comprehensive tests and README documentation.
Prompt: "Please review the changes we have made for this bucket api"
"we never used to have like so many emojis earlier and the look of the readme on github was really professional. can you please fix that"
"can you critique the readme"
- Remove emojis from features list and code examples for professional appearance
- Fix error handling in Quick Start example
- Add proper error checks for io.ReadAll
- Fix escaped newlines in printf statements (\\n to \n)
- Remove confusing SetEndpoint line from Quick Start
- Add ROADMAP.md with planned features through v1.0.0
- Update Contributing section to reference ROADMAP.md
