Summary

同一模型 id → Codex + Devin 候选
  Codex 额度用完 → 自动切 Devin:正常
  Devin 额度用完 → 再切回 Codex
-   出站 input 仍带着 Devin 历史里的 reasoning.status
-   Codex 报错:Unknown parameter: 'input[N].status'
+   仅当本候选 provider==Codex 且为 Responses:在该候选 body 副本上删掉 reasoning.status
+   Devin/其他候选不变(不回写缓存)

场景:Codex 与 Devin 配同一个模型 id。Codex 额度用完会自动切到 Devin;Devin 额度用完再切回 Codex 时失败。根因是 Devin 历史里的 reasoning 带有仅输出侧字段 status,Codex 不认 input[N].status。

改动:HTTP 与原生 Responses WebSocket 两条路径,仅在选中的 provider 是 Codex 时,从该候选的 prepared body 副本里删除 reasoning.status。保留 id / encrypted_content / summary / message.status / 工具对。不把清洗后的 body 写回 prepared-request 缓存或 continuation-recovery 状态。

Evidence

  • 改前: 带 reasoning.status 的 Devin 历史切回 Codex → 返回 Unknown parameter: 'input[N].status'。
  • 改后: 聚焦测全绿:
    • go test -count=1 ./internal/codexrecovery ./internal/gateway ./internal/execution/cpa -run 'Test(StripReasoningStatus|CodexReasoningStatus|ResponsesCodexReasoningStatus|WebsocketCodexReasoningStatus|CodexGatewayReasoningStatus)' → exit 0
  • Fork 合入 a679b8bd 后在 gate 实打硬样:经 Codex 的 POST /v1/responses,body 含 reasoning.status=completed → HTTP 200,不再出现 status 参数错误。

Merge Danger

门: 双向(可回滚)

影响面: 解析到的 provider 为 Codex 的 OpenAI Responses 尝试。其他 provider、非 Responses 协议不变。

自查清单 / Checklist

  • 已跑聚焦 Go 测(见上);本 cherry-pick 未重跑全量 make check,范围与 fork PR#17 一致。
  • 本 PR 范围聚焦,未夹带无关改动(相对 tbphp/main 仅 8 个文件)。
  • 无需改三份 README(内部 gateway failover,无用户可见文案变更)。
  • 提交、日志与测试数据无敏感信息。
  • 无数据迁移;反向样:Devin/其他 provider、非 Responses 路径行为不变。

Walkthrough

新增 StripReasoningStatus,用于移除 input 中 reasoning 项目的 status 字段。HTTP 和 WebSocket Responses 请求仅在目标 provider 为 Codex 时调用该处理逻辑。新增测试覆盖其他字段和提供方请求的保留,以及多轮请求、候选切换和上游出站请求。

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 15 functions across 8 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

感谢修复!问题成立,修法方向也对(在发往 Codex 前删掉 reasoning 条目的 status)。我在本地把 PR 合入最新 main 后跑了相关测试,都能通过。只有一处需要调整:这段逻辑放的层级。

现在:gateway(删 status)→ execution/cpa → providers/codex → cpaembedded Codex 执行器 → CPA
建议:gateway → execution/cpa → providers/codex → cpaembedded Codex 执行器(删 status)→ CPA

原因:

  • 这是 Codex 上游自己的限制,应该和其他 Codex 请求修正(请求头规范化、CPA 的 ID 清理)放在一起。gateway 只负责路由、重试和换号,目前没有按渠道改写请求体的先例。
  • codexrecovery 的约定是只在上游报错后才改写请求,正常请求不改写(见 doc.go)。StripReasoningStatus 每次正常请求都会改写,放在这个包里会打破这个约定。
  • 放到执行器里,每次调用拿到的本来就是请求副本,不需要再额外保证「不写回缓存、换号后 Devin 不受影响」,网关层那批测试也就可以去掉了。

建议改法:

  1. 在 third_party/cpaembedded/embedded 里新增 prepareCodexExecutionRequest(参照 prepareGrokExecutionRequest),把现有的 normalizedCodexHeaders 收进去。当请求是 Responses 格式(sdktranslator.FormatOpenAIResponse)时,用 sjson.DeleteBytes 删掉 input 里 reasoning 条目的 status,只删这一个字段,不重新编码整个请求体。在 ExecuteCanonical 和 ExecuteStreamCanonical 入口调用它。
  2. WebSocket 在 CodexWSSession.ExecuteTurn 发送前做同样的处理。
  3. 删除 internal/gateway/codex_reasoning_status.go、handler.go 和 websocket_turn.go 里的两处调用、网关层的两个测试文件,以及 codexrecovery.StripReasoningStatus 和它的测试。
  4. 测试:在嵌入层补一个删字段的单元测试,HTTP 和 WebSocket 两个入口都要覆盖;internal/execution/cpa/codex_reasoning_status_gateway_test.go 这个出站测试保留。

Codex Responses 出站仍只删除 input 中 reasoning 条目的 status。
清理改在 cpaembedded 的 prepareCodexExecutionRequest / ExecuteTurn 进行,
并去掉 gateway 与 codexrecovery 中的重复实现。

抱歉,还发现一个需要修复的地方(是我上次建议的写法导致的):

stripCodexReasoningStatus 每删一个 status 都调用一次 sjson.DeleteBytes,每次都要复制整个请求体,历史越长越慢,500 条 reasoning 时单次请求约 1 秒。麻烦改成只遍历一次 input,最后用 sjson.SetRawBytes 一次写回。

cursoragent and others added 3 commits November 7, 2026 09:44
数组分支对条目局部删除 status,有变更时一次 SetRawBytes。
无匹配返回原文;单对象路径不变。

生成器在关闭 input 后再写 metadata,不再提前结束根对象。
测试与 benchmark 先校验 json.Valid 和 metadata.n 字面量。
