When an S3 upload has a mismatched Content-MD5 header, SeaweedFS was
incorrectly returning a 500 Internal Server Error instead of the proper
400 Bad Request with error code BadDigest (per AWS S3 specification).
Changes:
- Created weed/util/constants/filer.go with error message constants
- Added ErrMsgBadDigest constant for MD5 mismatch errors
- Added ErrMsgOperationNotPermitted constant for WORM permission errors
- Added ErrBadDigest error code with proper 400 status code mapping
- Updated filerErrorToS3Error() to detect MD5 mismatch and return ErrBadDigest
- Updated filer autoChunk() to return 400 Bad Request for MD5 mismatch
- Refactored error handling to use switch statement for better readability
- Ordered error checks with exact matches first for better maintainability
- Updated all error handling to use centralized constants
- Added comprehensive unit tests
All error messages now use constants from a single location for better
maintainability and consistency. Constants placed in util package to avoid
architectural dependency issues.
Fixes#7305
Protocol
Otherwise any requests to the underlying handlers results in calls to
ListObjects (v1) that may intensively load gateway and volume servers.
Added the following handlers with default responses:
- GetBucketLocation
- GetBucketRequestPayment
Added the following handlers with NotFound and NotImplemented responses:
- PutBucketAcl
- GetBucketPolicy
- PutBucketPolicy
- DeleteBucketPolicy
- GetBucketCors
- PutBucketCors
- DeleteBucketCors
