📝 WalkthroughWalkthroughThe comment domain now supports cursor-based root and reply pagination, reply previews, structured writer metadata, active-reply limits, locking, and updated deletion authorization. Integration tests cover these flows. Database credentials and Gemini review workflow configuration now use environment-backed and repository-scoped operations. ChangesComment domain
Environment and review automation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The PR adds soft-delete comment behavior and related reply handling, but the current changes can break review automation, allow untrusted users to invoke credential-backed processing, expose replies from hidden posts, enable repeated anonymous deletion guesses, and corrupt comment counts during concurrent deletion; test configuration may also destroy an unintended database or prevent startup. Merge should be blocked until these issues are fixed or explicitly accepted by the responsible owners. Sequence Diagram(s)sequenceDiagram

idx_comment_post_parent_created (post_id, parent_id, created_at, comment_id)는 루트 댓글 조회 패턴과 정확히 맞습니다.post_id동등 조건,parent_id IS NULL동등 조건, 그 뒤created_at, comment_id범위 및 정렬이 하나의 인덱스 레인지 스캔으로 처리됩니다.filesort가 발생하지 않고, 커서가 뒤로 갈수록 비용이 증가하지 않습니다.선행 컬럼 뒤에
comment_id를 넣어 타이브레이커까지 인덱스로 커버한 점이 특히 좋습니다.created_at이DATETIME(초 단위)이므로 동일 시각 댓글이 흔하게 발생하는데, 이때 정렬이 비결정적이면 커서 페이징에서 항목 누락과 중복이 생깁니다.sameCreatedAtUsesIdTieBreaker테스트가 이 계약을 고정하고 있어 설계와 검증이 일치합니다.
idx_comment_parent_created (parent_id, created_at, comment_id)도 대댓글 분리 조회와countByParentIdAndIsDeletedFalse의 선행 컬럼을 모두 충족합니다.한 가지 운영 관점 확인 사항입니다. 이 파일은 신규 생성 DDL이므로 문제가 없지만, 이미 운영 중인

⚠️ [문제점 및 근거]:CommentService.validateDeletePermission은 Line 243에서comment.getMember() != null을 먼저 확인하고, 참이면 비밀번호 경로를 아예 실행하지 않습니다. 그런데createComment는 로그인 회원이isAnonymous = true로 댓글을 쓸 때 회원과 익명 비밀번호를 모두 저장합니다(Line 51-62). 즉 이 조합의 댓글은 비밀번호를 알아도 삭제할 수 없고, 오직 작성 회원 본인과 관리자만 삭제할 수 있습니다.이 동작은 합리적이지만, 현재 테스트는
createMemberComment(회원+공개)와createGuestAnonymousComment(비회원+익명) 두 조합만 다룹니다. 네 가지 권한 조합 중 가장 판정이 미묘한 조합이 검증되지 않습니다.💥 [영향 시나리오]: 나중에 누군가 Line 243의 조건을
comment.isAnonymous()기준으로 "정리"하면, 회원이 쓴 익명 댓글을 비밀번호만 아는 제3자가 삭제할 수 있게 됩니다. 현재 테스트는 이 회귀를 잡지 못하고 전부 통과합니다.🛠️ [개선 권장 코드]: 조합별 픽스처와 테스트를 추가하세요.

under the run: | block in the workflow, matching the YAML indentation of the
surrounding shell content at line 44; keep the heredoc contents unchanged so the
workflow parses them as shell text.
- Line 63: Update the Gemini request construction in the workflow so the review
policy is supplied through the system_instruction field, while PR_TITLE,
PR_BODY, and PR_DIFF are passed only as clearly delimited untrusted data in the
user prompt. Add an adversarial prompt-injection test covering malicious PR
content and verify the review still follows the policy and reports security
findings.
- Line 14: Update the workflow trigger condition around the existing
pull-request and /gemini-review checks to require an approved commenter
permission or explicit actor allowlist before running. Also add deduplication or
rate limiting for externally contributed pull requests, while preserving the
existing command and pull-request context requirements.
- Line 69: Update the Gemini request in the workflow’s RESPONSE assignment to
include connection and overall timeouts, visible curl errors, and failure on
HTTP 4xx/5xx responses using the requested curl options. Capture and validate
curl’s exit status before posting the PR comment, while preserving the existing
response handling and adding no retries.
- Line 38: Update the PR diff capture in the workflow so it does not silently
truncate output with head -c 12000; capture the complete gh pr diff output in
bounded chunks, or explicitly fail when the supported size is exceeded, ensuring

루트 댓글은 "활성 자식이 있을 때만 tombstone으로 노출"이라는 명확한 규칙(Line 82-85)을 갖는데, 대댓글에는 대응 규칙이 없습니다. 즉 정책이 코드 한 곳에 정의되어 있지 않습니다.
💥 [장애/영향 시나리오]: 대댓글 6건 중 3건이 삭제된 루트를 가정합니다.
- 목록 API:
replyCount = 3, 프리뷰는 삭제분 포함 5건,hasMoreReplies = true. - 대댓글 API:
totalReplyCount = 3인데replies에는 6건이 담깁니다.
프론트가 replyCount로 "답글 3개"를 렌더링하고 실제 6개를 그리면 사용자에게 즉시 보이는 불일치가 됩니다. 더 나쁜 경우는 hasMoreReplies입니다. 활성 대댓글이 2건뿐인데 삭제분 때문에 전체가 6건이면 true가 되어, 프론트는 "더보기"를 노출하고 사용자는 빈 목록을 받습니다.

💥 락 획득 순서가 엇갈려 대댓글 생성에서 데드락이 발생합니다.
- Line 94:
findByIdForUpdate(request.parentId())→ 요청된 부모 행에PESSIMISTIC_WRITE - Line 108:
findByIdForUpdate(rootCommentId)→ 루트 행에PESSIMISTIC_WRITE - Line 116:
findActiveReplyIdsForUpdate(rootCommentId)→ 루트의 모든 활성 자식 행에PESSIMISTIC_READ(backend/src/main/java/com/ikae/snowthing/domain/comment/repository/CommentRepository.javaLine 23-25)
즉 "자식 → 루트 → 자식 전체" 순서로 락을 잡습니다. 3번 단계가 다른 요청이 1번 단계에서 이미 잡은 자식 행을 요구할 수 있으므로, 락 획득 순서가 요청마다 달라집니다.
💥 [장애/영향 시나리오]: 루트 R 아래에 대댓글 X, Y가 있고 두 사용자가 각각 X와 Y에 답글을 답니다.
- 스레드 A: X 락 획득 → R 락 획득 → R의 자식 전체(X, Y) 공유 락 요청 → Y 대기
- 스레드 B: Y 락 획득 → R 락 요청 → R 대기
A는 Y를, B는 R을 기다리는 순환 대기가 완성됩니다. MySQL이 한쪽을 강제 롤백하므로 사용자에게는 원인 불명의 500이 나가고, innodb_lock_wait_timeout 동안 커넥션이 점유되어 인기 게시글에서 HikariCP 고갈로 번집니다. 현재 동시성 테스트는 하나의 루트에 직접 답글을 다는 경로만 검증하므로 이 순서 역전을 잡지 못합니다.
추가로 Line 116은 개수만 필요한데 최대 100건의 ID를 애플리케이션으로 끌어올려 .size()를 호출합니다. 불필요한 행 전송과 락 범위 확대입니다.
🛠️ [개선 권장 코드]: 락 지점을 루트 한 행으로 단일화하세요. 루트 행 하나만 잠그면 순서 역전이 원천적으로 불가능하고, 대댓글 수 검증도 그 락 아래에서 직렬화됩니다. 부모 식별은 락 없이 조회하면 충분합니다.
🛠️ 단일 락 지점으로 재구성

if (activeReplyCount >= MAX_REPLY_COUNT) {
throw new CustomAuthException(ErrorCode.COMMENT_REPLY_LIMIT_EXCEEDED);
}
}루트 행 락이 같은 트랜잭션에서 유지되는 동안 countActiveReplies가 실행되므로 상한 검증의 정합성은 그대로 유지됩니다. 변경 후에는 "같은 루트의 서로 다른 대댓글에 동시 답글" 시나리오를 동시성 테스트에 추가해 주세요.

Spring Boot externalized configuration official documentation .env file default configuration source environment variables
💡 Result:
As of September 2, 2026, Spring Boot does not have built-in, native support for automatically loading a file named.env by default [1][2]. Spring Boot's externalized configuration system is designed to automatically detect and load application.properties and application.yaml files from specific default locations [3][4]. It does not include.env files in this automatic discovery process [3][4]. If you wish to use.env files for configuration, you must explicitly configure Spring Boot to import them. The recommended approach is to use the spring.config.import property in your application.properties or application.yaml file [1][5]. For example: spring.config.import=optional:file:.env[.properties] This configuration tells Spring Boot to treat the.env file as a property source [1][5]. Using the optional: prefix prevents the application from failing to start if the file is missing (e.g., in production environments where environment variables are provided by the platform instead) [1]. Regarding configuration precedence, Spring Boot processes configuration sources in a defined order, typically allowing later sources to override earlier ones [6]. Environment variables are a primary, first-class configuration source in Spring Boot and are automatically detected by the framework [3][4]. They generally have high precedence, allowing them to override properties defined in application.properties or application.yaml files [3][7]. Top results: [3][1][5][7]

Document SNOWTHING_DB_PASSWORD injection for local and deployed launches.
application.yml requires this variable for both local and docker, prod. The Compose file passes it only to MySQL, and the documented bootRun command does not export it. Spring Boot does not load the root .env file by default, so local startup can fail during datasource configuration. Add explicit launcher/container injection or document the required export command.

In `@backend/src/main/resources/application.yml` at line 43, Document and ensure
SNOWTHING_DB_PASSWORD is injected for both local bootRun and deployed
docker/prod launches, updating the relevant launcher or container configuration
so Spring Boot receives the variable instead of relying on the root .env file.

[제안] 삭제할 때 잠금 없이 findById로 읽어 동시 삭제 두 건이 모두 isDeleted=false를 보고 댓글 수를 동시삭제하는 건 수 만큼(두번) 줄일 수 있습니다. 여기의 잠금 조회를 삭제에도 사용하거나 조건부 UPDATE 성공 건에만 카운트를 차감해주세요.

[제안] 익명 응답은 writer가 null이라 로그인 회원이 작성한 익명 댓글도 isOwnerAnonMember가 항상 거짓입니다. 본인 댓글인데 비밀번호를 요구하게 되므로 소유 유형을 응답에서 구분해 서버 권한과 맞춰주세요.

[제안] 익명 댓글이면 작성자 확인 없이 삭제 버튼을 보여 다른 회원의 로그인 익명 댓글에도 노출됩니다. 서버와 동일하게 회원 소유 익명과 비회원 익명을 구분해야 합니다.

[제안] 삭제 후 루트 목록은 다시 가져오지만 replyPagingByRootId는 초기화하지 않습니다. 새 미리보기와 과거 cursor가 섞일 수 있으니 함께 재구성해주세요.

[제안] 대댓글 5개 상태에서 새 답글을 추가하면 미리보기가 6개가 되지만 더보기 상태는 그대로입니다. 최대 5개 제한과 hasMoreReplies를 함께 갱신해주세요.

[제안] 백엔드 Long/BIGINT 식별자와 cursor를 프론트 number로 처리하면 MAX_SAFE_INTEGER 초과 시 다른 댓글을 수정·삭제하거나 cursor가 깨질 수 있습니다. API에서 문자열로 전달하는 게 안전합니다.

[제안] 댓글 조회 실패를 사용자에게 표시하지 않아 서버 오류도 빈 목록처럼 보입니다. 로딩·빈 목록·실패 상태를 구분하고 재시도 UI를 제공해주세요.
