feat(api): abort signal support for opencode-go, unbound, vercel-ai-gateway, zoo-gateway - #1295
Conversation
📝 SummarySummary by CodeRabbit
WalkthroughProvider handlers now forward abort signals and positive timeouts to SDK requests. Non-positive timeouts are omitted. Streaming paths normalize cancellations and remove bridged abort listeners. Tests cover cancellation, timeout handling, error identity, cleanup, and calls without options. ChangesProvider cancellation and request options
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to Cancellation behavior remains inconsistent and one streaming format leaks task-scoped listeners. These issues should be corrected before merge. Sequence Diagram(s)sequenceDiagram

- Around line 490-501: The completePrompt timeout handling must treat timeoutMs:
0 as no SDK timeout, excluding the timeout option from the OpenAI client request
while preserving normal positive-timeout behavior. Update the affected provider
tests, including the ZooGatewayHandler coverage, to verify zero is omitted and
all providers handle this consistently.
In `@src/api/providers/opencode-go.ts`:
- Around line 167-180: Remove bridged abort listeners after every request
completes: in src/api/providers/opencode-go.ts:167-180, update createMessage to
name the handler and remove it in finally around the remaining flow, including
streamAnthropicMessage; in src/api/providers/unbound.ts:152-165 and
src/api/providers/vercel-ai-gateway.ts:71-86, remove the named handler in
finally around each stream-consumption loop; in
src/api/providers/zoo-gateway.ts:220-233, add the cleanup to the existing
try/catch via finally. A shared bridgeAbortSignal helper may centralize this
behavior if it preserves each provider’s existing abort handling.

…o abort-signal utils The OpenAI-family provider PRs (Zoo-Code-Org#1309, Zoo-Code-Org#1311) carry per-provider copies of the same abort-detection helper (isRequestAborted) and the same abort-error constructor (createAbortError); only the provider name in the message differs. Per the CodeRabbit maintainability finding on Zoo-Code-Org#1309 (extract the shared abort helpers into utils/abort-signal.ts), these are now shared in the foundation utility: - isRequestAborted(error, signal?) - true when the caller signal fired, a native AbortError / OpenAI SDK APIUserAbortError was raised, or the message is exactly "Request was aborted." (exact match; a substring match would misclassify unrelated errors that merely mention aborting) - createAbortError(providerName) - fresh error with name === "AbortError" and message "The <providerName> request was aborted", satisfying the Task.ts abort contract - exported OpenAiRequestOptions type 7 new tests (isRequestAborted 4, createAbortError 3).

Assert the exact abort listener reference. The provider paths store abortListener and remove that same reference. These tests use expect.any(Function), so a mismatched listener can pass. Capture the handler from addEventListenerSpy.mock.calls and assert that removeListenerSpy receives it in both tests, including the Anthropic-format test.

Update both abort-listener tests, including the Anthropic-format test, to

removeListenerSpy was called with that exact reference alongside "abort".
Replace the broad expect.any(Function) listener assertion while preserving the

Check the abort signal before resolving the model. createMessage awaits resolveModel(), which awaits fallible model-catalog requests before reading metadata.abortSignal. A pre-aborted request can therefore start catalog work, and a resolution error can escape before the streaming path normalizes cancellation to AbortError. Call throwIfAborted(metadata?.abortSignal) before resolveModel().

Detach the Responses-format abort listener in finally
OpencodeGoHandler.createMessage registers abortListener on the task-scoped metadata.abortSignal, but the format === "responses" branch has no cleanup. Each completed or failed request therefore leaves its listener and captured AbortController attached to the shared signal. Wrap the streamResponsesMessage delegation in try/finally and remove the same listener.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Mid-stream cancellation is not normalized on the Unbound streaming path.
The inner try at lines 183-197 covers only chat.completions.create(...). The stream consumption loop at lines 200-228 has no catch, so a rejection raised after the stream starts propagates unchanged. When the external signal fires mid-stream, the caller receives the raw SDK rejection instead of the standardized AbortError. src/api/providers/__tests__/unbound.spec.ts lines 637-642 confirm this: the test aborts mid-stream and asserts message is "boom".
The OpenCode Go OpenAI path normalizes the same case (src/api/providers/opencode-go.ts lines 325-332). Align Unbound so mid-flight cancellation keeps the AbortError contract, then update the mid-stream test to assert the standardized error.
