feat(api): abort signal support for openai, openai-compatible base, zai, kimi-code (round 2) - #1311
Conversation
…ssion tests Add a fast-fail throwIfAborted guard to the shared abort-signal utilities and regression tests for the CompletePromptOptions interface (added by Zoo-Code-Org#901).
…ai, kimi-code (round 2) Round 2 of the abort-signal series: wires request-cancellation signals through the OpenAI family of providers (addresses Zoo-Code-Org#404). - openai.ts: all five client.chat.completions.create sites (createMessage streaming + non-streaming, O3-family streaming + non-streaming, completePrompt) build their request config through RequestConfigBuilder; the Azure AI Inference path option and the abort signal compose in one builder (setOption("path", ...) + setAbortSignal). Every catch normalizes abort failures to the Task.ts contract shape (name === "AbortError", message ending in "aborted") via an abort-aware handleOpenAIRequestError; non-abort errors keep the existing provider-prefix wrap. - base-openai-compatible-provider.ts: the shared createMessage / createStream / completePrompt path adopts RequestConfigBuilder for signal forwarding and gains the exported abort-aware error helper handleOpenAIRequestError (reused by zai.ts); subclasses that do not override these methods inherit the wiring. - zai.ts: audit finding fixed - the GLM thinking path in createStream no longer drops requestOptions; the thinking path and the glm-5.3 completePrompt path forward a merged signal (external signal + timeoutMs via mergeAbortSignalAndTimeout). - kimi-code.ts: completePrompt no longer drops CompletePromptOptions - options are forwarded on both the initial call and the 401 OAuth retry. - Design notes: CompletePromptOptions is not ApiHandlerCreateMessageMetadata (required taskId, gap G7), so completePrompt paths use setOption("signal", mergeAbortSignalAndTimeout(...)) instead of setAbortSignal(metadata); gap G5 - mergeAbortSignalAndTimeout treats timeoutMs <= 0 as no explicit timeout. Each call builds a fresh request-local config (no class-field abort controller) with a per-entry-point throwIfAborted guard that rejects before any network I/O. - eslint-suppressions.json: one stale suppression entry pruned (kimi-code.spec.ts @typescript-eslint/no-explicit-any 1 -> 0 - the spec rewrite removed the only as-any cast); no suppression count increased. This branch is STACKED on open PR Zoo-Code-Org#1288: the foundation commit e61feb1 (generic RequestConfigBuilder, mergeAbortSignalAndTimeout, mergeAbortSignals, throwIfAborted) rides inside by design.

named imports in the openai and zai providers resolve correctly. Change only the
type declaration’s visibility and preserve its existing signal field and shape.
- Around line 146-151: Wrap async stream consumption in the relevant method of
the base OpenAI-compatible provider with try/catch, passing iteration errors to
handleOpenAIRequestError(error, this.providerName, metadata?.abortSignal) so
AbortError results are normalized. In

328-346, add a regression test using an async iterator whose next() rejects with
AbortError and assert the resulting name is AbortError and message is

…ks and sambanova specs
Root cause: the abort-aware completePrompt error path inherited by fireworks
and sambanova (base-openai-compatible-provider.ts) references the
APIUserAbortError export of the openai SDK, which their specs' partial
vi.mock("openai", ...) factories did not define, so the completePrompt
error-path tests failed in the CI full suite with
'No "APIUserAbortError" export is defined on the "openai" mock'.
The mocks now export APIUserAbortError using the same shape as the other
series specs (base-openai-compatible-provider, zai, openai, kimi-code).
Root cause: the creation-site catches only cover chat.completions.create; an abort that surfaces while the async iterator is being consumed (APIUserAbortError / fetch-level AbortError thrown mid-stream) leaked as the raw SDK error, which violates the Task.ts abort contract (an Error whose name is "AbortError" and whose message ends in "aborted"). The stream iteration is now wrapped and normalized through the same abort-aware handleOpenAIRequestError used at the creation sites: - base-openai-compatible-provider.ts: the createMessage for-await loop - openai.ts: the streaming createMessage for-await loop - openai.ts: the o3-family yield* this.handleStreamResponse(stream) The Z.ai thinking path inherits the base createMessage iteration, so it is covered by the base-provider fix. Non-abort iteration errors keep the existing provider-prefix wrap. Adds four regression tests (base, openai streaming, o3-family streaming, zai thinking path) with iterators that reject with APIUserAbortError after yielding the first chunk. Addresses the CodeRabbit pre-merge review comment on PR Zoo-Code-Org#1311.

…eration wrapper The stream-iteration wrapper added in 35c95ea routes non-abort iteration errors through handleOpenAIRequestError, so a provider base_resp stream error (MiniMax-style inline error chunk) is now rethrown with the provider-prefix wrap ("TestProvider completion error: ...") instead of the raw message. Adds a focused regression test that yields a chunk carrying base_resp and pins the wrapped message.

… openai abort paths The codecov patch report (97.83% at 217f120) flagged 2 partial branch lines (BRDA taken=0 on the ?? / || fallback sides of added lines): - api/providers/base-openai-compatible-provider.ts:171 branch 1 of `${...} ${chunkAny.base_resp.status_msg || "Unknown error"}` - the || "Unknown error" fallback was never exercised; added a focused test yielding a base_resp chunk with status_code set but no status_msg, asserting the wrapped "Unknown error" message. - api/providers/openai.ts:233 branch 1 of `const delta = chunk.choices?.[0]?.delta ?? {}` - the ?? {} fallback (chunk with no delta field) was never exercised; added a focused streaming test yielding a delta-less final chunk and asserting the stream completes without throwing. Full api/providers suite: 1698 passed. No provider code changed.
…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).

- base-openai-compatible-provider.completePrompt now forwards a positive timeoutMs as the per-request SDK timeout (RequestOptions.timeout); without it the OpenAI client falls back to the client-level default and can expire before a larger per-request timeoutMs. - base spec adds a timeout-only test (no caller signal) that exercises the timeout branch alone: the request signal aborts when timeoutMs elapses and the pending request rejects with the normalized abort error; the merged-signal test also asserts the forwarded timeout. - zai GLM-5.3 spec now keeps the mocked request pending, aborts the caller signal before awaiting, and asserts the in-flight request rejects with the normalized abort error. - kimi-code pre-abort tests use OAuth authentication so the OAuth-mock skip assertions are not vacuous (resolveAccessToken would invoke the mocks without the guards).

Sync: merged upstream/main (0d937c0) to clear the merge conflict. One conflicting file: src/api/providers/tests/openai.spec.ts — both sides added tests after "should handle streaming responses" (branch-side streaming edge-case tests from this unit; main-side Extra Body tests from #1350). Resolution keeps both sets (6 tests); no semantic changes, openai.ts merged cleanly. Local gates on the merged head:
Still stacked on #1288 (foundation commit unchanged); standalone unit diff is unchanged by this sync. |

Description
Round 2 of the abort-signal series: wires request-cancellation signals through the OpenAI family of providers.
client.chat.completions.createsites (createMessage streaming + non-streaming, O3-family streaming + non-streaming, completePrompt) build their request config throughRequestConfigBuilder, adopted from the start of this PR — the Azure AI Inferencepathoption and the abort signal compose in one builder (setOption("path", ...)+setAbortSignal). Every catch now normalizes abort failures to the Task.ts contract shape (name === "AbortError", message ending inaborted) via an abort-awarehandleOpenAIRequestError, while non-abort errors keep the existing provider-prefix wrap.createMessage/createStream/completePromptpath adoptedRequestConfigBuilderfor signal forwarding and gains the exported abort-aware error helperhandleOpenAIRequestError(reused by zai.ts). Subclasses that do not override these methods (fireworks, sambanova, baseten) inherit the wiring.createStreamno longer dropsrequestOptions; the thinking path and the glm-5.3completePromptpath forward a merged signal (external signal +timeoutMsviamergeAbortSignalAndTimeout).completePromptno longer dropsCompletePromptOptions— options are forwarded on both the initial call and the 401 OAuth retry.createMessageinherits the openai.ts wiring via metadata passthrough.Design notes:
CompletePromptOptionsis not assignable toApiHandlerCreateMessageMetadata(requiredtaskId) — gap G7 — so completePrompt paths usesetOption("signal", mergeAbortSignalAndTimeout(...))instead ofsetAbortSignal(metadata).mergeAbortSignalAndTimeouttreatstimeoutMs <= 0as no timeout internally, so atimeoutMs: 0call site passes no signal rather than a timeout that would abort immediately.RequestOptionstype does not satisfy the builder'sRequestConfigOptionsBaseconstraint (itsheaders/signalshapes differ), so each provider declares a minimal localOpenAiRequestConfigshape as the builder generic parameter.throwIfAbortedguard rejects before any network I/O when the signal is already aborted.This branch is STACKED on #1288: the foundation commit
