Description

Stacked on #3748

Mandeuldang problem의 update와 publish 뮤테이션을 구현하였습니다.

  1. UpdateMandeuldangProblemInput dto 구현
  2. 발행 조건 확인 함수 check 구현 (publish-check.service.ts)
  3. updateProblem 뮤테이션 구현
    1. 수정 권한 검증 (Owner와 Editor만 수정 가능)
    2. input 값에 따라 해당 문제를 update ($transaction)
    3. status가 published인 문제인 경우 발행 조건을 만족하지 못했을 때 throw error
    4. status가 draft인 문제인 경우 발행 조건을 만족하였을 때 ready로 status 승격
    5. status가 ready인 문제인 경인 발행 조건을 만족하지 못하였을 때 draft로 status 강등
    6. 수정된 문제 반환
  4. publishProblem 뮤테이션 구현
    1. 발행 권한 검증 (Owner만 발행 가능)
    2. status가 ready가 아닌 경우 throw error
    3. 발행조건을 만족하지 못한 경우 throw error
    4. 조건을 만족하면 status를 published로 update
    5. update된 문제 반환

📝 Walkthrough

Walkthrough

The PR adds Mandeuldang problem update and publish mutations, shared publish-readiness checks, authorization and status transitions, seed fixtures, resolver and service tests, and Bruno API requests.

Changes

Mandeuldang problem lifecycle

Layer / File(s) Summary
Management GraphQL API
apps/backend/apps/admin/src/mandeuldang/problem/model/problem.input.ts, apps/backend/schema.gql, apps/backend/apps/admin/src/mandeuldang/problem/resolvers/*, apps/backend/apps/admin/src/mandeuldang/problem/problem.module.ts, apps/backend/apps/admin/src/mandeuldang/problem/resolvers/problem.resolver.spec.ts
Adds the update input and GraphQL mutations. Resolvers delegate update and publish operations to the service. Status arguments use the generated ProblemStatus type. Resolver tests check delegation with the expected arguments.
Lifecycle service and publish validation
apps/backend/apps/admin/src/mandeuldang/problem/services/problem.service.ts, apps/backend/apps/admin/src/mandeuldang/problem/services/publish-check.service.ts, apps/backend/apps/admin/src/mandeuldang/problem/services/problem.service.spec.ts
Adds publish-readiness checks for statement fields, languages, limits, solutions, and test files. Updates enforce authorization and input validation, transition problems between Draft and Ready, and preserve publish conditions for Published problems. Publishing requires an Owner, Ready status, and passing publish checks. Service tests cover these cases.
Fixtures and API validation
apps/backend/prisma/seed.ts, collection/admin/Mandeuldang Problem/...
Adds test files to seeded Ready and Published problems. Adds Bruno requests for successful updates and publishing, authorization failures, missing records, invalid limits, empty titles, and failed publication conditions.

Merge Risk: 🟡 Moderate · up to 196f1

Unpublished problems and submission data may still be exposed through the reported query paths. Resolve those access concerns before merging; also correct the publish test so it protects the intended status rule.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 196f1

The new operations enforce distinct editing and publishing roles and check publication requirements. Authorization is checked before the database write, however, so a concurrent change to a collaborator’s permissions could leave an in-flight mutation authorized under stale permissions. The affected scope appears to be an individual problem; a reachable permission-revocation path was not established.

Retained concerns

  • Medium · security · inferred: Editing and publishing authorize a collaborator before starting the write transaction. If approval or role can be revoked concurrently, an already-started mutation can complete after revocation because its write predicates do not recheck authorization. No concurrent revocation entrypoint was established, so reachability remains conditional.
Security review details

Security Blast Radius

  • inferred — The identified authorization gap concerns an in-flight mutation of a problem for which the caller passed an earlier permission check. The inspected mutations do not establish broader tenant, service, or environment authority.

Security Findings and Attack Paths

  • inferred — A previously approved collaborator could submit an edit or publish request, then have their role or approval revoked before the write; the write checks problem ID, and for publishing Ready status, but not current collaborator authorization. Whether an application path permits this concurrent revocation is unverified.

Trust Boundaries and Controls

  • observed — The resolver supplies the request user ID rather than a GraphQL-supplied identity. Service checks distinguish editing from publishing authority and restrict the publish write to Ready problems; global authentication enforcement was not verified.

Resilience and Maintainability Implications

  • observed — The shared eligibility check treats any nonempty test-file row set as sufficient. The inspected generator path creates paired input and output files transactionally; a production path that leaves only one file was not established.

Hardening Proposals

  • proposed — If collaborator permissions can change while mutations are in flight, make authorization and the protected write one concurrency-safe operation, with an appropriate predicate or lock for the permission record.

- Around line 56-57: Constrain getInProgressMandeuldangProblems so its status
handling only permits Draft and Ready, preventing Published from reaching
getInProgressProblems or its where.status filter. Reject unsupported statuses or
enforce the Draft/Ready constraint while preserving valid behavior, and add a

In
`@apps/backend/apps/admin/src/mandeuldang/problem/services/problem.service.spec.ts`:
- Around line 415-417: Update the authorization stub around approve and

collaboratorId, and returns null for any other user ID; keep the test setup and
updateProblem call unchanged.

In `@apps/backend/apps/admin/src/mandeuldang/problem/services/problem.service.ts`:
- Around line 243-250: Update updateProblem so the status-changing transaction
returns the row produced by tx.problem.update instead of the stale updated
value; preserve the existing updated return path when nextStatus already matches
problem.status.

In
`@apps/backend/apps/admin/src/mandeuldang/problem/services/publish-check.service.ts`:
- Line 42: Update PublishCheckService.check to determine the TEST_FILES
requirement from problem.mandeuldangTestFiles rather than
problem.problemTestcase, preserving the existing missing-entry behavior when no
uploaded Mandeuldang test files exist.
- Around line 34-37: Validate timeLimit and memoryLimit as positive values in
updateProblem before persisting supplied updates, rejecting zero or negative
inputs. Retain the existing final validation in PublishCheckService so
publishProblem cannot publish problems with non-positive limits, and ensure
JudgeRequest continues receiving only valid positive limits.

266-273: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Return the row from the status update. The earlier fix is not in this code.

If nextStatus !== updated.status, the code writes the new status but discards the result. The code then returns updated, which still holds the old status. After a Draft→Ready promotion or a Ready→Draft demotion, the mutation returns a stale status. The past review comment was marked addressed, but the current code still has the defect.

🐛 Proposed fix
       if (nextStatus !== updated.status) {
-        await tx.problem.update({
+        return await tx.problem.update({
           where: { id: problem.id },
           data: { status: nextStatus }
         })
       }
       return updated

The spec cannot detect this defect. The update stub returns the merged baseline, but the tests never assert result.status. Add an assertion on the returned status.

the problem still matches the state checked for readiness and publishability;
use a concurrency token or equivalent conditional update and reject publication
when that check fails. Do not rely on a ReadCommitted transaction alone.

569-582: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Exercise the Ready-status guard in the “not yet Ready” test.

The default findUniqueOrThrow fixture is incomplete, so PublishCheckService.check throws Cannot publish: missing ... before updateMany runs. The default { count: 1 } result also cannot detect removal of the Ready-status guard.

Use a complete publishable snapshot, force updateMany to return { count: 0 }, and assert Only a Ready problem.

♻️ Suggested fix
       db.mandeuldangCollaborator.findUnique.resolves({
         role: CollaboratorRole.Owner,
         status: CollaboratorStatus.Approved
       })
+      db.problem.findUniqueOrThrow.resolves({
+        ...readyToPublishSnapshot,
+        status: ProblemStatus.Draft
+      })
+      db.problem.updateMany.resolves({ count: 0 })

       try {
         await service.publishProblem(10, ownerId)
         expect.fail('should have thrown')
       } catch (err) {
-        expect((err as Error).message).to.include('Cannot publish')
+        expect((err as Error).message).to.include('Only a Ready problem')
       }

around lines 569 - 582:
Update the “not yet Ready” test for `service.publishProblem` to reach the
Ready-status guard: configure `findUniqueOrThrow` with `readyToPublishSnapshot`
overridden to Draft and make `updateMany` return `{ count: 0 }`. Assert that the
error includes “Only a Ready problem” so the test verifies the guard rather than
an earlier missing-data failure.
