Here is the question of why will have this fixed string

This string is the SHA256 hash of the empty string. In S3 chunked uploads, when an empty chunk (content_size = 0) is encountered, the SHA256 hash of the empty string is used as the payload hash.

This is a standard requirement of the AWS S3 protocol. Each block transfer must end with an empty block, which is part of the protocol specification and is used to mark the completion of the transfer and perform final signature verification.

It is recommended to use this string as a constant and add an annotation

Why do we need this S3 gateway? If Curvine already provides a FUSE interface, we could use the MinIO gateway directly, similar to how JuiceFS does. If our goal is better performance rather than a gateway that delegates all network traffic, we might consider introducing a Curvine agent to simulate the S3 interface on each client side. |

There is no need to annotate every variable

Streamline the annotation！
- Fix incorrect prefix directory traversal logic in ListObjectHandler - Change from prefix-as-directory to proper string prefix matching - Move bucket path calculation outside async block to fix lifetime issues - Add proper prefix filtering with starts_with() method - Ensure S3 standard compliance for list-objects-v2 --prefix parameter Test improvement: 89% -> 92% pass rate (Test 7.1 now passes)

First of all, why not use MinIO Gateway + FUSE directly? Because there is a performance bottleneck. The FUSE layer adds additional system call overhead. Each S3 operation must go through: S3 client → MinIO Gateway → FUSE → kernel → Curvine. The multi-layer conversion leads to increased latency and CPU consumption. In addition, the file system semantics of FUSE do not fully match the object storage semantics of S3, and it is difficult to ensure the consistency of concurrent access. The suggestion about Curvine worker s3 Agent is indeed valuable, and support will be considered in scenarios with higher performance requirements in the future. It is still necessary to provide a centralized gateway at present. Many machine learning and AI training directly use the s3 client. Curvine provides a standard s3 gateway to make it more convenient for users to access. |
Key fixes: 1. Replace redundant field names in struct initialization 2. Use ok_or() instead of ok_or_else() with closures 3. Replace len() > 0 with is_empty() checks 4. Fix redundant pattern matching using is_err() method 5. Use strip_prefix() instead of manual string slicing 6. Combine nested format calls to reduce allocations 7. Initialize struct fields directly instead of reassignment 8. Rename utils module to s3_utils to avoid name conflicts 9. Remove unused lifetime parameters 10. Improve code quality following Rust best practices All changes maintain functionality while improving performance.
- Create custom AuthError type for extract_args function - Add allow annotation for too_many_arguments - Combine duplicate if conditions in PutObjectOption - Fix to_string usage in format! macro - Ensure all code passes GitHub CI clippy checks
