Adds abort signal + timeout support to the OpenAI Codex provider. completePrompt now uses a request-local signal built from options.abortSignal/timeoutMs (merged via the shared mergeAbortSignalAndTimeout util), and createMessage bridges metadata.abortSignal into the provider's internal request AbortController using the Bedrock pattern, covering both the OpenAI SDK streaming path and the manual SSE fetch fallback.

  • Provider: src/api/providers/openai-codex.ts
    • completePrompt: request-local signal via mergeAbortSignalAndTimeout(options?.abortSignal, options?.timeoutMs) (falls back to a fresh AbortController signal); handler-wide this.abortController no longer used on the fetch path; abort errors re-thrown as-is so cancellation is detectable by name === "AbortError"
    • createMessage/executeRequest: metadata param added; external abortSignal bridged into the internal controller (pre-aborted guard + { once: true } listener)
  • Tests:
    • src/api/providers/tests/openai-codex.spec.ts: ported reference completePrompt suite (request body/headers, timeoutMs=0 no-timeout, abortSignal and abortSignal+timeoutMs merging, empty/text-fallback outputs, unauthenticated and non-ok error paths, reasoning config, ChatGPT-Account-Id header cases), plus focused tests that a pre-aborted signal and an in-flight abort both reject with name === "AbortError"
    • src/api/providers/tests/openai-codex-native-tool-calls.spec.ts: createMessage abort bridge test (external signal propagates to the internal controller signal) and pre-aborted test (internal signal already aborted before the request starts)

Part of the abort-signal series (round 1). Builds on #674, #901, #1008. Addresses #404.

Summary by CodeRabbit

  • Bug Fixes

    • Improved cancellation handling for streamed Codex requests.
    • External cancellation signals now stop requests promptly, including requests already cancelled at startup.
    • Combined request timeouts and cancellation signals more reliably.
    • Cancellation and timeout failures are reported consistently for clearer error handling.
    • Improved handling of Codex response options, authentication retries, and image content in streaming requests.
  • Tests

    • Added comprehensive coverage for request construction, responses, authentication, timeouts, cancellation, and error scenarios.

…eateMessage)

- completePrompt: use a request-local signal built with mergeAbortSignalAndTimeout(options?.abortSignal, options?.timeoutMs) for the fetch call instead of the handler-wide AbortController; re-throw abort errors as-is so cancellation is detectable by the "AbortError" name
- createMessage: pass metadata into executeRequest and bridge metadata?.abortSignal into the internal AbortController (Bedrock pattern: pre-aborted guard + { once: true } listener), covering both the OpenAI SDK streaming path and the manual SSE fetch fallback
- specs: port the reference completePrompt coverage (request body, timeoutMs=0, abortSignal/timeoutMs merging, error paths) and add pre-aborted and in-flight abort tests rejecting with name === "AbortError"; port the createMessage abort bridge + pre-aborted tests into the native tool calls spec

📝 Walkthrough

Walkthrough

OpenAI Codex now propagates external abort signals through streamed and synchronous requests. completePrompt combines caller signals with timeouts, passes the combined signal to fetch, extracts response text, and normalizes cancellation errors. Tests cover request construction, cancellation, responses, failures, reasoning, service tiers, images, and account headers.

Changes

OpenAI Codex request cancellation

Layer / File(s) Summary
Streaming signal bridge
src/api/providers/openai-codex.ts, src/api/providers/__tests__/openai-codex-native-tool-calls.spec.ts
Streaming execution bridges external abort signals to a request-local controller, passes the signal to the SDK, stops iteration after cancellation, and cleans up listeners. Tests cover active and pre-aborted signals.
Completion request and response handling
src/api/providers/openai-codex.ts
completePrompt combines caller and timeout signals, passes the signal to fetch, extracts the first matching output or top-level text, returns an empty string when no output exists, and normalizes aborted requests to AbortError.
Completion behavior validation
src/api/providers/__tests__/openai-codex.spec.ts
Tests cover request construction, service tiers, timeouts, cancellation, response extraction, failures, reasoning options, encrypted reasoning, and optional account headers.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 76d79

The OpenAI Codex provider’s manual streaming fallback can associate cancellation with the wrong concurrent request, causing one request to be cancelled by another or preventing the intended request from stopping. The PR is not merge-ready until the fallback uses the request-local signal or the risk is explicitly accepted.

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

501-504: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not use SSE fallback after cancellation.

When responses.create() rejects with AbortError, this catch starts makeCodexRequest() with the same aborted signal. The fallback then converts the cancellation into a connection error. Rethrow cancellation errors before the fallback. Use the fallback only for non-cancellation SDK failures or unusable responses.

- executeRequest: create a request-local AbortController (mirrored to this.abortController for existing abort handling); the external-signal bridge listener now captures the local controller and is removed in finally, so a late abort from an earlier request can no longer abort a newer request and listeners no longer leak
- completePrompt: normalize any rejected request whose request-local signal aborted (external abort, AbortSignal.timeout "TimeoutError") to an error with name "AbortError", and throw the same AbortError when the transport quietly completes after cancellation
- specs: bridge test now asserts the captured request-local SDK signal aborts mid-flight; merge tests assert AbortError rejection on quiet completion; new tests cover timeout cancellation and quiet completion after abort

507-509: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Pass the request-local signal through the SSE fallback.

Line 509 calls makeCodexRequest(), but that method still reads this.abortController for fetch and stream processing. If another request starts before this fallback reaches fetch, it replaces the field. The fallback can then use the other request's signal. An abort for request A can fail to cancel request A, and an abort for request B can cancel request A.

Pass requestController.signal as an explicit parameter to makeCodexRequest() and handleStreamResponse(). Add a test that forces responses.create() to fail, starts a second request, and verifies that the fallback fetch uses the first request's signal.
