fix(remote): cancel expired workspace mutations - #5841
Conversation

@lidge-jun @Wibias Please review the encrypted deadline/cancel protocol and the fail-closed queued-mutation behavior. This is security-sensitive Remote Workspace control flow. @codex security review |

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe remote-workspace RPC protocol advances to version 2. Coordinators prepare requests with bounded deadlines, grant execution only while requests remain pending, and send cancellation on timeout. Endpoints retain prepared requests until grant, cancellation, timeout, or closure. Tests and documentation cover these protocol changes. ChangesRemote workspace RPC

Merge Risk: 🔵 Low · up to The English guide explains the v2 upgrade requirement and timeout behavior, but four translated guides omit it. Readers of those locales may miss compatibility and cancellation limits; this is a bounded documentation issue, so merge risk is low.

리뷰 · 우선순위 72 / 80이 PR은 원격 작업실에서, 기다리는 시간이 끝난 파일 쓰기가 나중에 실행되지 않게 하려는 수정이에요. 명령을 보내는 쪽은 암호화된 요청마다 기다릴 시간을 같이 보냅니다. 기본은 30초에서 65초로 늘고, 직접 정해도 120초를 넘기지 못합니다. 65초는 명령 한도 60초보다 조금 깁니다. 시간이 끝나면 "취소했다"가 아니라 "취소를 요청했다"고만 말합니다. 파일을 쓰는 쪽은 요청을 받은 순간부터 그 시간만큼 타이머를 켭니다. 앞에서 다른 작업이 도는 동안 줄 서 있던 쓰기는, 자기 차례에 이미 취소됐으면 파일을 만들지 않습니다. 보내는 쪽이 기다림을 멈추면 암호화된 취소 편지도 보냅니다. 이 결정은 ADR-0108에 적혀 있습니다. 기준 브랜치는 dev입니다. 같은 내용으로 닫을 다른 PR은 없습니다. 줄 뒤에 있던 쓰기가 시간 초과 뒤에 파일을 안 만드는 것은 테스트로 확인됩니다. 그 테스트의 앞 명령은 취소를 일부러 무시합니다. src/remote-control/workspace-rpc.ts:169 - 보내는 쪽 타이머는 요청을 다 보내기 전에 시작합니다. 전송이 막혀 그 시간보다 오래 걸리면, 사용자에게는 이미 시간 초과라고 답합니다. 요청 자체는 그 다음에 나갑니다. 메인테이너의 판단이 필요한 지점 도착한 뒤 기다릴 시간을 다시 주는 방식을 유지할지 정해 주세요. ADR-0108은 컴퓨터마다 시계가 달라서, 요청에 끝나는 시각을 적지 않기로 했습니다. 그 선택이면, 보내는 쪽이 이미 포기한 요청도 줄이 비어 있을 때 파일을 쓸 수 있습니다. 작성자가 물은 대로, 이 TypeScript 경로와 짝인 Go 코드가 있는지도 확인해 주세요. 너의 추천 보내는 쪽 시간이 이미 끝난 요청이 빈 줄로 도착하면 파일을 만들지 않는 테스트를 먼저 넣으세요. 그 테스트가 실패하는 동안은 머지하지 마세요. 고칠 때는 도착한 뒤에 기다릴 시간을 다시 주지 말고, 이미 포기된 요청은 쓰기 전에 거절하세요. 줄에 쌓인 작업을 취소하는 지금 동작은 그 테스트와 같이 남기세요. 이 댓글은 grok-bot이 작성했습니다 |

Keep the translated Remote Workspace guides in sync.
The Japanese, Korean, Russian, and Simplified Chinese guides omit the new RPC compatibility and timeout behavior. Add equivalent content covering the RPC v2 requirement, v1 fail-closed behavior, cancellation semantics, and timeout bounds.
