Relaxed regex validation in utils.go to support hyphens in S3 Tables
namespaces and table names, improving consistency with S3 bucket naming
and allowing derived names from services like S3 Storage Lens.
Refactored resolveResourcePath to return resource type, enabling accurate
NoSuchBucket vs NoSuchTable error codes. Added existence checks before
deleting policies.
Added VersionToken validation to handleDeleteTable. Refactored table
listing to use request context for accurate ARN generation and fixed
cross-namespace pagination issues.
Updated namespace creation to use authenticated account ID for ownership
and unified permission checks across all namespace operations to use the
correct account principal.
Ensured bucket ownership is correctly attributed to the authenticated
account ID and updated ARNs to use the request-derived account ID. Added
standard S3 existence checks for bucket deletion.
Updated getPrincipalFromRequest to prioritize X-Amz-Account-ID header and
added getAccountID helper. Defined ErrVersionTokenMismatch and ErrCodeConflict
for better optimistic concurrency support.
- Correctly handle io.EOF in handleListNamespaces and handleDeleteNamespace.
- Propagate other errors to prevent silent failures or accidental data loss.
- Added necessary io import.
- Correctly handle io.EOF to terminate loops gracefully.
- Propagate other errors to prevent silent failures.
- Ensure all list results are processed effectively.

- Improve error handling to distinguish between NotFound (404) and InternalError (500)
- Fix directory FileMode usage in filer_ops
- Improve test randomness for version tokens
- Update permissions comments to acknowledge IAM gaps
- Pre-compile regex patterns as package-level variables to avoid re-compilation overhead on every call
- Add a random component to version token generation to reduce collision probability under high concurrency
- Update handleGetNamespace to distinguish between 404 and 500 errors
- Refactor CanManagePolicy to use CheckPermission for consistent enforcement
- Ensure empty identities are correctly handled in policy management checks
- Implement strict table name validation (prevention of path traversal and character enforcement)
- Add nil checks for entry.Entry in all listing loops to prevent panics
- Propagate backend errors instead of swallowing them or assuming 404
- Correctly map filer_pb.ErrNotFound to appropriate S3 error codes
- Standardize existence checks across bucket, namespace, and table handlers
- Prohibit path traversal (".", "..") and "/" in namespaces
- Restrict namespace characters to [a-z0-9_] for consistency
- Switch to url.PathUnescape for correct decoding of ARN path components
- Align ARN parsing regex with single-segment namespace validation
- Migrate from custom ErrNotFound to filer_pb.ErrNotFound
- Use filer_pb.LookupEntry for automatic error normalization
- Normalize entryExists and attribute lookups
- Remove mandatory ACTION_ADMIN at the router level
- Enforce granular permissions in bucket and namespace handlers
- Prioritize AccountID in ExtractPrincipalFromContext for ARN matching
- Distinguish between 404 (NoSuchBucket) and 500 (InternalError) in metadata lookups
- Clean up unused imports in s3api_tables.go
- Update generateTableARN to match AWS S3 Tables specification
- Move defer r.Body.Close() to follow standard Go patterns
- Remove unused generateNamespaceARN helper
- Fix InclusiveStartFrom logic to ensure exclusive start on continued pages
- Prevent duplicates in bucket, namespace, and table listings
- Fail fast on listing errors during bucket and namespace deletion
- Stop swallowing errors in handleListTables and return proper HTTP error responses
- Add multi-segment namespace support to ARN parsing
- Refactor permission checking to use map lookup
- Wrap lookup errors with ErrNotFound in filer operations
- Standardize splitPath to use path package
- Add permissions.go with permission definitions and checks
- Define permissions for all 21 S3 Tables operations
- Add permission checking helper functions
- Add getPrincipalFromRequest to extract caller identity
- Implement access control in CreateTableBucket, GetTableBucket, DeleteTableBucket
- Return 403 Forbidden for unauthorized operations
- Only bucket owner can perform operations (extensible for future policies)
- Add AuthError type for authorization failures
- Specifically check for 'not found' errors instead of catching all errors
- Return empty list only when directory doesn't exist
- Propagate other errors (network, permission) with context
- Prevents masking real errors
- Reduce handler.go from 370 to 195 lines (47% reduction)
- Remove duplicate ARN parsing and path helper functions
- Remove filer operation methods moved to filer_ops.go
- Remove metadata structure definitions moved to utils.go
- Keep handler focused on request routing and response formatting
- Maintains all functionality with improved code organization
- Create bucket_create.go for CreateTableBucket operation
- Create bucket_get_list_delete.go for Get, List, Delete operations
- Related operations grouped for better maintainability
- Each file has a single, clear responsibility
- Improves code clarity and makes it easier to test
