fix(omp): wait for native background settlement before completing turns by BytePioneer-AI · Pull Request #826 · BytePioneer-AI/codex-host

BytePioneer-AI · 2026-11-12T14:47:54Z

Summary

等待 OMP 原生后台工作静止，不再因 terminal agent_end 后仍 streaming 而立即 fault。
按 Turn 锁存 session_settled，用一次有界串行重查覆盖通知/状态竞态；旧通知不能单独结算新 Turn。
新 native run 必须有自身完成事实；保留 local 结果和 agentInvoked: false 身份、既有取消语义，并同步文档与回归测试。

Refs #825
Related PR #707（仅提取 settlement 修复，不含 steer、Host queue 或 Renderer 改动）

Validation

冻结基线三项反例：1 pass / 2 fail；当前同三项：3 pass。
确认期间新 run 启动的 agent/local × 两种帧顺序：修前 local 两项提前结算，修后四项通过。
OMP 聚焦回归：199 passed / 1 skipped（原生 ask 用例未启用）。
OMP 生产类型、所有 OMP 测试的聚焦类型检查、改动 TS ESLint、TS/文档 Prettier、boundary 与 diff 检查通过；未运行全仓检查。

验证为 macOS arm64 上真实 TS RPC/JSONL 实现配合 Fake Process，不是原生 OMP 后台作业、真实模型或 Desktop 端到端验收；Windows/Linux 未验证。有界重查不保证任意长的原生状态滞后，无新原生事实时不会虚构完成。

Summary

Summary by CodeRabbit

修复
- OMP 本地命令在没有后台运行时可正常完成；若有后台任务继续运行，系统会等待其结束。
- 会话仍在处理中时，完成状态不会被提前确认；后台任务结束后，回合状态可正确更新。
文档
- 更新 OMP 交互说明，补充本地命令与回合完成状态的行为描述。

此更改调整 OMP 回合的完成确认。会话根据当前回合的完成事实和会话状态决定是否结束回合，并在结算通知早于空闲状态更新时进行一次延迟重查。

Changes: OMP 回合结算

Layer / File(s)	Summary
跟踪回合完成事实与结算通知 `packages/adapters/omp/src/omp-rpc-session.ts`	`ActiveTurn` 跟踪 agent 启动和结算通知。只有终止事件，或尚未启动 agent 的本地结果，才能作为完成事实。事件处理会在 agent 启动时更新完成状态。
确认会话结算并覆盖竞态 `packages/adapters/omp/src/omp-rpc-session.ts`, `packages/adapters/omp/test/omp-rpc-session.test.ts`, `docs/harnesses/omp/omp-interactions.md`	回合完成后，代码查询会话状态，并在收到结算通知但状态仍繁忙时延迟重查一次。测试覆盖过期通知、新后台运行、繁忙状态和定时器清理；文档同步说明完成规则。

Suggested reviewers: qiyi71w, kongtou20070406

Merge Risk: Low · up to e0907

The change makes OMP turns wait for background work to finish before completing and adds a bounded recheck for notification/state races. One scenario remains unhandled: a turn that yields and whose background job is cancelled with no follow-up run can still hang. This behavior existed before this PR. Consider handling it here or as a follow-up.

Treat a correlated nonterminal yield as Turn completion

When an agent yields with background work pending, OMP can emit agent_end with isTerminal: false, followed by the prompt-correlated prompt_result; if that work is later cancelled or its delivery is suppressed, no follow-up run or terminal agent_end is guaranteed, and session_settled is the final frame. Because prompt_result with agentInvoked: true is ignored and this condition requires terminalEnd, the settle notice is discarded and runTurn() remains pending forever. Track the matching prompt result/yield as this Turn's completion fact before applying the session-quiescence barrier. This ordering and the absence of a guaranteed follow-up are specified by the OMP v18.4.10 RPC protocol.

允许已 yield 的回合在原生 Session 空闲后完成。

当 agent_end 的 isTerminal 为 false 时，terminalEnd 不会被设置。若随后后台作业被取消，且没有新的 agent_start，session_settled 会被忽略，因为 hasTurnCompletion 为 false。#confirmSettledTurn 不会执行，回合无法进入 confirmed 状态，runTurn 无法结束，下一回合也无法提交。

该路径在 PR 前同样不会完成，本 PR 未改变此行为。

OMP 文档规定 prompt_result 在最终 yield 时到达，且 session_settled 总在其之后到达。awaitingAsyncWork: true 的非终结 agent_end 可能没有后续 run。因此，应将 yield 作为完成资格，并在新的 agent_start 到达时清除该资格。#confirmSettledTurn 仍通过 get_state 检查 isSettled、hasPendingAsyncWork 和队列，因此在仍有后台工作时不会确认完成。

建议修改

terminalEnd: boolean; + yielded: boolean; sawAgentStart: boolean;

- return active.terminalEnd || (active.localResult !== null && !active.sawAgentStart); + return active.terminalEnd || active.yielded || (active.localResult !== null && !active.sawAgentStart);

terminalEnd: false, + yielded: false, sawAgentStart: false,

if (value.type === "agent_start" && active) { active.terminalEnd = false; + active.yielded = false; active.sawAgentStart = true; }

if (value.type === "prompt_result") { - if (value.id !== active.promptId || value.agentInvoked !== false) return; + if (value.id !== active.promptId) return; + if (value.agentInvoked === true) { + active.yielded = true; + return; + } + if (value.agentInvoked !== false) return;

补充回归测试：agent_end（isTerminal: false）后接 prompt_result（agentInvoked: true），随后取消后台作业，再收到 session_settled。断言回合完成。另补充一个用例：同一回合在 session_settled 前收到新的 agent_start，断言旧的 yield 资格被清除。
