🎋 작업중인 브랜치 및 이슈

🔑 주요 변경사항

  • 목소리를 바꾸면 해당 회원의 모든 routine_tts 행을 PENDING으로 되돌리고, 행마다 RoutineTtsVoiceChangedEvent를 발행해 백그라운드에서 재합성합니다.

  • 재합성 전용 스레드풀(ttsRegenerateExecutor)을 분리했습니다. 생성 경로(ttsExecutor)와 큐를 공유하지 않아 재합성 폭주가 신규 루틴 TTS를 굶기지 않습니다.

  • 두 풀 모두 종료 시 진행 중 작업을 기다리도록 설정하고, 컨테이너에 stop_grace_period: 90s를 추가했습니다.

  • 기존 음원은 새 음원 저장이 확정된 뒤에 삭제합니다. 먼저 지우면 실패 시 들려줄 음원이 사라집니다.

Summary by CodeRabbit

  • New Features

    • Added voice-selection version tracking to member and routine TTS responses.
    • Changing a selected voice now automatically regenerates affected routine audio.
    • Routine TTS regeneration preserves existing audio if replacement fails.
    • Added an error response for missing voice configuration.
  • Improvements

    • Improved TTS processing capacity and graceful shutdown behavior.
    • Added a longer shutdown grace period for production services.

충돌 3파일 해결:
- docker-compose.prod.yml: stop_grace_period 와 logging(awslogs) 둘 다 유지
- RoutineTTSRepository: 양쪽이 추가한 쿼리 4개 모두 유지
- TTSAsyncService: dev 의 MemberWithdrawalLock 체크·회원별 S3 키 경로·
  로그 sanitize 규약을 재합성(regenerate) 경로에도 동일 적용

TTSAsyncServiceTest 는 ttsRegenerateExecutor 인자와
RoutineTtsCreatedEvent 의 voiceVersion 추가에 맞춰 수정

📝 Walkthrough

Walkthrough

The change adds member voice-selection versioning, propagates versions through routine TTS creation and responses, and regenerates routine audio asynchronously after voice changes. It also adds bounded executors, graceful shutdown settings, validation, and updated tests.

Changes

Voice-versioned TTS regeneration

Layer / File(s) Summary
Member voice-version contract and orchestration
src/main/java/com/moru/server/domain/member/..., src/main/java/com/moru/server/domain/routine/repository/..., src/main/java/com/moru/server/global/response/...
Members persist and expose voice-selection versions. Voice updates validate configuration, skip unchanged selections, mark routine TTS records pending, and publish versioned change events.
Versioned routine TTS contracts and creation flow
src/main/java/com/moru/server/domain/routine/entity/..., src/main/java/com/moru/server/domain/routine/event/..., src/main/java/com/moru/server/domain/routine/service/command/RoutineGroup/..., src/main/java/com/moru/server/domain/routine/dto/..., src/main/java/com/moru/server/domain/routine/service/query/...
Routine TTS records, creation events, creation flows, repository queries, and API responses carry voice-version values.
Asynchronous TTS regeneration
src/main/java/com/moru/server/domain/routine/service/command/RoutineTTS/TTSAsyncService.java, src/test/java/com/moru/server/domain/routine/service/command/RoutineTTS/TTSAsyncServiceTest.java
Voice-change events dispatch regeneration. The service validates versions, creates replacement audio, preserves prior audio on failure, and removes obsolete audio after success.
Async execution and shutdown support
src/main/java/com/moru/server/global/config/AsyncConfig.java, docker-compose.prod.yml
TTS executors use bounded pools and graceful shutdown. The production app receives a 90-second stop grace period.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 17108

This change rebuilds a member’s routine audio after a voice change, but the current implementation can fail deployment, leave audio stuck in a pending state, or restore audio generated with an older voice; disabled TTS can also report a version that does not match the stored audio. These issues should be fixed before merging.

Add tests for the voice-change regeneration flow.

Test a successful replacement, a stale version that deletes the new upload without saving it, and failures before upload completion. These cases protect the new version and previous-audio contracts.

- Around line 48-50: Add a database migration for the new
voice_selection_version column on members, defining it as non-null with a
default of 0 and backfilling existing rows to 0. Ensure it is applied before
Hibernate validation runs and matches the schema conventions used by existing
migrations.

In
`@src/main/java/com/moru/server/domain/member/service/command/member/MemberCommandServiceImpl.java`:
- Around line 51-59: Update the voice-selection flow in MemberCommandServiceImpl
so bumpVoiceSelectionVersion() runs for every successful voiceType update,
including when ttsEnabled is false; only skip requestRegeneration in disabled
mode. Ensure the response retains the incremented version and preserve the
existing routine-TTS status behavior unless an explicit status change is
required by the surrounding contract.

In
`@src/main/java/com/moru/server/domain/routine/service/command/RoutineTTS/TTSAsyncService.java`:
- Around line 151-161: Move the regeneration precondition lookups and
withdrawal-lock check in TTSAsyncService into the existing try block so
exceptions are handled by the failure path. Ensure failures from findById,
findMemberIdByRoutineTtsId, or memberWithdrawalLock.isLocked invoke the
established failure-state handling and do not leave the RoutineTTS row pending.
- Around line 128-132: The completion flow around RoutineTTS entity updates must
use an atomic conditional update keyed by the member selection version matching
voiceVersion, covering both the creation and existing-result paths. Replace the
separate version check and save operations with this conditional write; when no
row is updated, delete uploadedKey and preserve the current audio.

작업 거절 시 상태가 PENDING에 남습니다

executor의 최대 작업 수와 큐가 모두 차면 @Async 작업은 메서드 본문에 진입하기 전에 거절됩니다. 그러면 아래 try/catch와 markFailedQuietly가 실행되지 않아 해당 TTS는 영구히 PENDING으로 남습니다. 거절 핸들러에서 상태를 FAILED로 전환하거나, DB 작업 큐와 재시도 워커로 처리해 주셔야 합니다!
