feat(api): abort signal support for openai, openai-compatible base, zai, kimi-code (round 2) - #1311
easonLiangWorldedtech wants to merge 55 commits into
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.

Full details: Lifecycle Resource Cleanup

Explanation
The changed Kimi preparation path can keep work active after cancellation.
createMessageandcompletePromptpass the caller signal toprepareRequest(src/api/providers/kimi-code.ts:111-130), butresolveAccessTokenstill callsgetAccessToken()andforceRefreshAccessToken()without that signal (:63-71). If the OAuth token is expired, the refresh usesrefreshKimiCodeAccessTokenwithout a signal (src/integrations/kimi-code/oauth.ts:242-274), so its fetch and timeout continue after cancellation. Model discovery has the same gap: Kimi is auth-scoped, andgetModelsdeliberately calls the provider fetch without the caller signal (src/api/providers/fetchers/modelCache.ts:210-236);KimiCodeHandler.fetchModelsthen callsgetKimiCodeModels(options.apiKey)without options (src/api/providers/kimi-code.ts:59-61). The new fetcher signal and timeout cleanup (src/api/providers/fetchers/kimi-code.ts:42-69) therefore do not protect the actual Kimi handler path. A cancellation during OAuth refresh or model discovery can leave the network operation and timer active until settlement.Resolution
Thread the caller
AbortSignalthroughresolveAccessToken,KimiCodeOAuthManager.getAccessTokenandforceRefreshAccessToken,refreshKimiCodeAccessToken, andpostForm, then pass it to the OAuth fetch. Forward the signal through the auth-scoped model-cache dispatch andKimiCodeHandler.fetchModelstogetKimiCodeModels. Preserve timeout and abort-listener cleanup on every settlement path. Keep the post-preparation and pre-retry abort checks so cancellation cannot issue completion or retry requests.

…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).

modelCache.ts:314-315 forwards the caller's own signal to getKimiCodeModels on the auth-scoped
cache-miss arm, because that arm runs without the single-flight controller. Nothing covered it:
mutation-diff reported NoCoverage mutants on both the `signal ?? options.signal` fallback and the
empty-options branch, and dropping either one left every existing test green.
Two tests in the getModels describe:
- signal set -> getKimiCodeModels called with (apiKey, { signal });
- no signal -> called with exactly one argument, so no options object is fabricated.
Negative controls: replacing the fallback with `const kimiSignal = signal` fails the first test;
dropping the options argument entirely fails the second. Both restored green.
Local: modelCache.spec + kimi-code.spec (providers + fetchers) + zai.spec = 175 passed / 0 failed;

The Kimi preparation signal checks and the named GLM-5.3 regression tests are also present. This supports your regression-coverage update. I did not run tests or verify the latest review verdict. The reported 175 passing tests remain your local validation. I will not trigger a separate full review because you did not request one. ✏️ Learnings added

One conflict: base-openai-compatible-provider.spec.ts - main prettier-collapsed the custom-model assertion to one line while this branch extended it to pin the two-argument create(body, requestConfig) call shape. Kept this branch's two-argument assertion (it does not fit one line, so main's reformat does not apply to it). Verification at this head: affected specs 512/514 passed - the 2 failures are the known stale-donor-junction artifact (this worktree's @roo-code/types junction points at a donor tree predating the strict-tool-schemas export, so DEFAULT_OPEN_AI_STRICT_TOOL_SCHEMAS is undefined at runtime); the same 8 strict-schema tests pass on a fresh-install worktree against the same main merge, and the merged production strict path is byte-identical to main. ESLint --max-warnings=0 clean on the resolved file; tsc shows only stale-donor missing-export artifacts (0 merge-caused errors in touched files); prettier clean; suppressions strictly below main (this PR removes one entry and lowers one count).
Prettier-only reformat of four files this PR touches (signature collapse in fetchers/kimi-code.ts, call wrapping in error-handler.spec.ts, and line joins in openai.spec.ts / modelCache.spec.ts). No semantic change; specs re-run identical (313 pass, 2 known stale-donor strict-default failures).

Conflicts resolved: - fetchers/modelCache.ts + its spec: main redesigned model fetching through the handler interface (handler.fetchModels(options, signal) + getModelCacheScope), replacing the fetcher-dispatch switch this branch threaded signal through (kimi arm). Main's redesign supersedes the branch hunks; took main's versions wholesale. The kimi signal forwarding the branch's two modelCache.spec tests pinned now lives at the fetcher level (fetchers/kimi-code.spec.ts) and at the call site (options.signal feeds the pre-abort fast-fail). - kimi-code.ts: merged both sides' imports (branch CompletePromptOptions + throwIfAborted; main ModelCacheScope + getKimiCodeModels) and combined the discovery call site: main's handler argument (this) plus the branch's options.signal. Verification at this head: 512/512 green across the eleven touched specs; tsc --noEmit 0 errors; eslint --max-warnings=0 clean on touched files; prettier clean.

prepareRequest set modelDiscoveryAttempted before awaiting getModels, so a caller cancellation that interrupted discovery left the flag set and every later request on the same handler skipped discovery and kept the fallback model metadata. The catch now resets the flag only when the failure is a cancellation (isRequestAborted against the caller's signal); ordinary discovery failures keep the one-attempt behavior. New test aborts during getModels, then makes a second request on the same handler and asserts discovery runs again (negative control verified: removing the reset fails the test; the test is order- independent - the fetch stub is installed before handler construction because the SDK binds globalThis.fetch at construction). Verification at this head: 25/25 green in kimi-code.spec.ts (isolated run of the new test also green); tsc --noEmit 0 errors; eslint --max-warnings=0 clean on touched files; prettier clean.

Conflict resolution: keep the branch's abort wiring (completePrompt fast-fail via throwIfAborted in the base provider and openai.ts; APIUserAbortError import in the base-provider spec). Post-merge lint repair for the re-enabled unused-variable rule: drop the now unused OpenAI default import in the spec and the handleOpenAIError import in the base provider (upstream removed its call sites), keeping handleOpenAIRequestError which remains in use. Also re-pointed the src/node_modules and root node_modules @roo-code/types and @roo-code/telemetry junctions back to this worktree's own packages (they had drifted to unrelated checkouts, which surfaced phantom CommandId errors under tsc). Verification at this merge: 454/454 green across the unit's ten spec files; tsc --noEmit 0 errors; eslint --max-warnings=0 clean (suppression count for base-openai-compatible-provider.ts reduced 6 -> 5, stale kimi-code.spec.ts entry pruned); prettier clean.

Closes #404 — the OpenAI-compatible cancellation objective, for the OpenAI provider family implemented in this PR (
openai,base-openai-compatible-providerand its inheritors,zai,kimi-code).This PR covers only the OpenAI-family portion of the broader provider sweep; the remaining scope lands via sibling PRs in this series:
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. Both streaming loops (the maincreateMessagepath and the O3-familyhandleStreamResponse) gain the loop-defense contract: a top-of-loop break stops processing buffered chunks that arrived after the caller's abort, and a post-loop check surfaces the Task.ts abort contract when the stream would otherwise end normally on an already-aborted signal.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, including the streaming loop's top-of-loop break and post-loop abort check.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
e61feb13e(genericRequestConfigBuilder,mergeAbortSignalAndTimeout,mergeAbortSignals,throwIfAborted) rides inside by design.Test Procedure
pnpm --dir src exec vitest run api/providers/__tests__/openai.spec.ts api/providers/__tests__/base-openai-compatible-provider.spec.ts api/providers/__tests__/zai.spec.ts api/providers/__tests__/kimi-code.spec.ts— all green. New per-provider "abort signal wiring" suites cover: signal identity at every create site (including Azure path composition), signal + timeout merging, thetimeoutMs: 0guard, pre-aborted rejection before any request, SDKAPIUserAbortErrorand fetch-levelAbortErrornormalization to the Task.ts contract shape, and non-abort provider-prefix wrap regression. Deferred-chunk kill tests (2 in openai.spec.ts incl. the O3-family path, 1 in the base spec) prove the loop defense structurally: the second chunk is released only after the abort, so the top-of-loop break is the only thing that prevents the leak (asserted via aleakedcollection), andcaptureErrorproves the post-loop check rejects with the contract message rather than a normal stream end.vitest run <specs> --coverage(v8/lcov) and cross-referenced against thegit diffadded lines.pnpm --dir src exec tsc --noEmit— exit 0.pnpm --dir src exec eslint --prune-suppressions --max-warnings=0 <changed files>— zero warnings; 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.Pre-Submission Checklist

setOption("signal", ...)StringLiteral mutant, a known flake class (the mutant drops the signal, so the abort test can only fail through the vitest timeout).Additional Notes
Part of the abort-signal series (round 2). Builds on #674, #901, #1008, and #1288. Addresses #404.
In-scope justification for the two non-#404-looking items
package.jsondevDependencyvitest 4.1.11: mutation-gate infrastructure — the changed-code mutation gate (Stryker via zdt) must resolve a vitest binary at the repository root to run this PR's gate (commit 0703c58), and the 4.1.11 pin is the CI dependency-review advisory bump (commit 4238bd1). It is the mechanism by which this PR's [BUG] Stop does not work on OpenAI Compatible API Provider #404 changes are gate-verified, not a functional change.base_respre-typing: the hunk is inside this PR's new abort-aware streaming loop inbase-openai-compatible-provider.ts— the same change adds the top-of-loopif (signal?.aborted) breakdefense and the try wrapper that normalizes abort errors raised during stream iteration ([BUG] Stop does not work on OpenAI Compatible API Provider #404 round 2, commits 393b516 and 35c95ea). The previouschunk as anyread was re-typed with an unknown guard in that restructure; behavior is preserved (same status_code/status_msg semantics and error message shape), covered by the base_resp stream-error path test (commit 217f120).Updated 2026-10-11 (head

The two-argument assertion is kept (it doesn't fit one line, so main's reformat doesn't apply to it).Verification at this head: affected provider/fetcher/util specs 512/514 passed — the 2 failures are
