Reverted the conditional versioning check to always check versioning status
Reverted the conditional SSE entry fetch to always fetch entry metadata
Reverted the conditional versioning check to always check versioning status
Reverted the conditional SSE entry fetch to always fetch entry metadata
* Lazy Entry Fetch for SSE, Skip Conditional Header Check
* SSE-KMS headers are present, this is not an SSE-C request (mutually exclusive)
* SSE-C is mutually exclusive with SSE-S3 and SSE-KMS
* refactor
* Removed Premature Mutual Exclusivity Check
* check for the presence of the X-Amz-Server-Side-Encryption header
* not used
* fmt
Added end-to-end logging to track SSE chunk metadata lifecycle:
**During Multipart Completion (filer_multipart.go)**:
1. Log finalParts chunks BEFORE mkFile - shows SseType and metadata
2. Log versionEntry.Chunks INSIDE mkFile callback - shows if mkFile preserves SSE info
3. Log success after mkFile completes
**During GET Retrieval (s3api_object_handlers.go)**:
1. Log retrieved entry chunks - shows SseType and metadata after retrieval
2. Log detected SSE type result
This will reveal at which point SSE chunk metadata is lost:
- If finalParts have SSE metadata but versionEntry.Chunks don't → mkFile bug
- If versionEntry.Chunks have SSE metadata but retrieved chunks don't → storage/retrieval bug
- If chunks never have SSE metadata → multipart completion SSE processing bug
Expected to show chunks with SseType=NONE during retrieval even though
they were created with proper SseType during multipart completion.
Added comprehensive logging to diagnose why TestSSEMultipartUploadIntegration fails:
detectPrimarySSEType now logs:
1. Total chunk count and extended header count
2. All extended headers with 'sse'/'SSE'/'encryption' in the name
3. For each chunk: index, SseType, and whether it has metadata
4. Final SSE type counts (SSE-C, SSE-KMS, SSE-S3)
This will reveal if:
- Chunks are missing SSE metadata after multipart completion
- Extended headers are copied correctly from first part
- The SSE detection logic is working correctly
Expected to show if chunks have SseType=0 (none) or proper SSE types set.
Critical fix for SSE (Server-Side Encryption) test failures:
1. **JWT Authentication Bug** (Root Cause):
- Changed from GenJwtForFilerServer to GenJwtForVolumeServer
- S3 API now uses correct JWT when directly reading from volume servers
- Matches filer's authentication pattern for direct volume access
- Fixes 'unexpected EOF' and 500 errors in SSE tests
2. **Streaming Error Handling**:
- Added error propagation in getEncryptedStreamFromVolumes goroutine
- Use CloseWithError() to properly communicate stream failures
- Added debug logging for streaming errors
3. **Response Header Timing**:
- Removed premature WriteHeader(http.StatusOK) call
- Let Go's http package write status automatically on first write
- Prevents header lock when errors occur during streaming
4. **Enhanced SSE Decryption Debugging**:
- Added IV/Key validation and logging for SSE-C, SSE-KMS, SSE-S3
- Better error messages for missing or invalid encryption metadata
- Added glog.V(2) debugging for decryption setup
This fixes SSE integration test failures where encrypted objects
could not be retrieved due to volume server authentication failures.
The JWT bug was causing volume servers to reject requests, resulting
in truncated/empty streams (EOF) or internal errors.
