- Add detailed logging for .versions metadata updates in putVersionedObject
- Add logging for latest version resolution in getLatestObjectVersion
- Add logging for HeadObject latest version requests
- All logs use glog.V(0) with CI-DEBUG prefix for easy filtering
- Will help diagnose timing issues between object creation and retrieval in CI
Debug logs will show:
- When .versions metadata updates start and complete
- When HeadObject tries to read latest version metadata
- Race conditions if HeadObject runs before metadata update completes
- Missing metadata if .versions directory exists but metadata keys are missing
- File access issues if version files exist but can't be accessed
Different Owner: Always fails with 409 BucketAlreadyExists
Checks the s3-identity-id header against the stored bucket owner
Returns error immediately if owners don't match
Same Owner + Conflicting Settings: Fails with 409 BucketAlreadyExists
Compares requested Object Lock settings with existing bucket configuration
Returns error if settings are incompatible (e.g., trying to enable Object Lock on a bucket that doesn't have it)
Same Owner + Compatible Settings: Returns 200 OK (idempotent)
If the bucket already exists with the same owner and compatible settings
Returns success response without recreating the bucket
