📝 WalkthroughWalkthroughS3 업로드가 완료된 혼잡 이벤트 이미지를 검증하고 이벤트에 연결하는 PATCH API를 추가했습니다. 이미지 상태를 Changes혼잡 이벤트 이미지 연결
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to 이 PR은 기존 혼잡 이벤트에 이미지를 연결하고 상태를 갱신하지만, 기존 데이터의 상태 필드 누락 및 이전 상태값과의 호환성 부족으로 배포 후 이벤트 조회·이미지 연결이 실패하거나 런타임 오류가 발생할 수 있으며, 동일한 완료 요청도 S3 상태에 따라 실패할 수 있습니다. 데이터 호환·마이그레이션과 멱등 처리 보완 또는 명시적 승인이 필요하므로 현재는 병합을 권장하기 어렵습니다.

In
`@src/main/java/com/saferoute/domain/congestion/service/CongestionEventImageService.java`:
- Around line 41-56: Update the completion flow in CongestionEventImageService
so that after validateState and validateObjectKey, a request matching
isSameCompletedImage(item, request) publishes the existing item via
publishImageUpdated and returns before any S3 objectExists check or
observationRepository.completeImageUpload call. Preserve normal S3 validation
and completion handling for non-idempotent requests, and add a test covering
repeated completion after the object is unavailable.
In
`@src/main/java/com/saferoute/domain/telemetry/dynamo/entity/ImageUploadStatus.java`:
- Line 5: Update the ImageUploadStatus enum and its persistence conversion so
existing DynamoDB records containing UPLOADED remain readable until migration
completes; retain a compatible UPLOADED enum value or converter mapping, and
ensure the deployment process backfills those stored values to COMPLETED before
removing compatibility.
In
`@src/main/java/com/saferoute/domain/telemetry/dynamo/repository/ObservationRepository.java`:
- Around line 124-134: Update the conditional update flow around
updateConditionally so legacy ObservationItem records without imageUploadStatus
are treated as PENDING, while retaining the existing PROCESSED and FAILED
handling. Apply the compatible behavior consistently in the service status
validation and the DynamoDB condition expression, or ensure existing records are
backfilled to PENDING before deployment.
In
`@src/test/java/com/saferoute/domain/congestion/controller/CongestionControllerTest.java`:
- Around line 278-289: Extend CongestionControllerTest around
connectEventImage_returnsBadRequestWithoutImageKey to cover service-thrown
ApiException cases: verify EVENT_NOT_FOUND returns HTTP 404 with the expected
error code, and EVENT_IMAGE_STATE_CONFLICT returns HTTP 409 with its expected
error code. Reuse the existing image-connection request setup and mocking
conventions.
In
`@src/test/java/com/saferoute/domain/congestion/service/CongestionEventImageServiceTest.java`:
- Around line 63-78: Extend CongestionEventImageServiceTest around connectImage
to cover authorization failures from validateCctv for both CCTV mismatch and
inactive CCTV cases. Assert the exception is propagated and verify that
objectExists, completeImageUpload, and publishCongestionImageUpdated are not
invoked after authorization is rejected.
In
`@src/test/java/com/saferoute/domain/telemetry/dynamo/repository/ObservationRepositoryTest.java`:
- Around line 171-189: Add a test alongside
PROCESSED이고_이미지가_PENDING_FAILED일_때만_이미지를_완료한다() that configures table.updateItem
to throw ConditionalCheckFailedException and verifies completeImageUpload
returns false, preserving the existing success-case assertions.
In `@src/test/java/com/saferoute/infrastructure/s3/S3ServiceTest.java`:
- Around line 113-119: Update S3ServiceTest around
returnsFalseWhenObjectDoesNotExist to add objectExists failure-mapping tests for
500 and 503 S3Exception responses and for a generic SdkException. Assert each
case throws ApiException with S3ErrorCode.OBJECT_CHECK_FAILED, while preserving
the existing 404 false-result test.
