fix: 팀원 모집 지원 마감일의 활동 시작일 제한 제거 - #2415
Conversation
지원 마감일이 활동 시작일 이하여야 한다는 제한을 검증 로직과 DB CHECK 양쪽에서 제거한다. 활동 시작 이후까지 지원을 받는 모집글이 있어 마감일은 활동 기간과 무관하게 받는다. 활동 시작일 <= 활동 종료일 제약은 유지한다. - validatePeriod 를 validateActivityPeriod 로 바꿔 마감일 비교 제거 - V7 마이그레이션으로 chk_team_recruitment_dates 재정의 - 도달 불가능해진 TEAM_RECRUITMENT_INVALID_DEADLINE_DATE 제거 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughTeam recruitment validation now allows deadlines after the activity start or end date. Activity start dates must still precede activity end dates. The API contract, error code, database constraint, migration, and tests reflect this rule. ChangesTeam recruitment deadline validation
Priority: ➖ Normal — Schedule the recruitment deadline change because it resolves a medium-severity validation issue across API requests and the database while preserving activity-date validation. Estimated code review effort: 3 (Moderate) | ~20 minutes Severity of issue fixed: Medium Merge Risk: 🟡 Moderate · up to The migration can briefly or permanently remove activity-date enforcement, allowing invalid recruitment periods.

site:dev.mysql.com/doc/refman/8.0/en/alter-table.html ALTER TABLE DROP CHECK ADD CONSTRAINT multiple alter specifications metadata lock
💡 Result:
In MySQL, you can combine multiple operations, such as DROP CHECK and ADD CONSTRAINT, into a single ALTER TABLE statement by separating them with commas [1]. When you perform multiple operations in one ALTER TABLE statement, the server treats the operation as a single unit [1]. Regarding metadata locks, the ALTER TABLE statement acquires the necessary metadata locks for the entire operation [1]. Specifically, an exclusive metadata lock on the table is typically taken during the execution phase (and sometimes the preparation phase, depending on the algorithm used) to ensure consistency while the metadata is updated [1]. Because the entire statement is processed together, the table is locked for the duration of the combined changes rather than acquiring and releasing locks for each individual specification separately [1]. You can also use the LOCK clause (e.g., LOCK=NONE, LOCK=SHARED, or LOCK=EXCLUSIVE) to explicitly control the level of concurrency permitted while these combined operations are being performed, provided the chosen algorithm supports it [1].

site:dev.mysql.com/doc/refman/8.0/en implicit commit ALTER TABLE metadata lock released statement end
💡 Result:
In MySQL, an ALTER TABLE statement triggers an implicit commit before it executes, which effectively ends any transaction active in the current session [1]. Because ALTER TABLE causes an implicit commit, metadata locks associated with the previous transaction are released when that transaction ends [2]. Regarding the ALTER TABLE statement itself: 1. In autocommit mode, each statement acts as a complete transaction; therefore, metadata locks acquired for the ALTER TABLE statement are typically released at the end of that specific statement [2]. 2. If ALTER TABLE is executed within a broader context, the implicit commit behavior ensures that any prior transaction is closed [1]. 3. Metadata locks acquired during DDL operations are held to maintain consistency; for instance, while an online DDL operation might only require an exclusive metadata lock briefly, it must wait for other sessions' active transactions holding metadata locks to commit or roll back before it can finish [3][4]. In summary, because ALTER TABLE triggers an implicit commit, it effectively ends the preceding transaction, ensuring that metadata locks tied to that transaction's scope are released [2][1]. Locks acquired by the ALTER TABLE statement itself are managed according to the requirements of the DDL operation (e.g., brief exclusive locks for table definition updates) and are generally released once the statement completes [2][4].

Keep chk_team_recruitment_dates enforced throughout the migration.
The two ALTER TABLE statements execute independently. MySQL commits each ALTER TABLE separately, so the first statement removes the constraint before the second restores it. A concurrent write can therefore persist invalid dates, and a failure in the second statement leaves the constraint absent.
Combine DROP CHECK and ADD CONSTRAINT in one ALTER TABLE statement, or stop all writes until both statements complete.

RecruitmentRequestValidator.validatePeriod(start, end, deadline)→validateActivityPeriod(start, end)로 변경해 마감일 비교를 제거했습니다. 인자만 남기면 죽은 파라미터가 되므로 시그니처에서 제외하고 호출부 두 곳(작성/수정)을 맞췄습니다. 활동 시작일 <= 활동 종료일 검증은 그대로 유지합니다.V7__relax_team_recruitment_deadline_date.sql추가 —chk_team_recruitment_dates를activity_start_date <= activity_end_date만 검사하도록 재정의합니다. 기존 행은 모두 완화된 조건을 만족하므로 재생성 시 실패하지 않습니다.TEAM_RECRUITMENT_INVALID_DEADLINE_DATE를ApiResponseCode와 작성/수정 API 의@ApiResponseCodes에서 제거했습니다.@Schema문구에서 제한 설명을 제거했습니다.테스트
