Adds abort-signal support to the native Ollama provider: completePrompt now honors CompletePromptOptions.abortSignal / timeoutMs (a pre-aborted signal rejects immediately with an AbortError; mid-flight aborts and timeouts abort the per-request client), and createMessage bridges metadata.abortSignal into the per-request client's abort(). Also ports the per-request _createOllamaClient() refactor (constructor headers option for the API key) that replaces the ensureClient() singleton.

Providers / paths touched:

  • src/api/providers/native-ollama.ts — completePrompt abort/timeout wiring (per-request client, pre-aborted AbortError, abort-listener + timeout cleanup in finally); createMessage external-signal bridging into the per-request client; ensureClient() singleton replaced by per-request _createOllamaClient() using the constructor headers option for ollamaApiKey.
  • src/api/providers/__tests__/native-ollama.spec.ts — reference abort/timeout completePrompt suite and per-request-client suite ported; new createMessage bridging tests.
  • src/eslint-suppressions.json — one-line prune: native-ollama.ts @typescript-eslint/no-explicit-any 3 -> 2 (removing the ensureClient() try/catch dropped one pre-existing violation; the pre-commit lint gate requires the ratchet to match the actual count).

Tests added:

  • completePrompt: request-local client when abortSignal is provided; no signal-related options when not provided; backward compatible without options; timeoutMs reached triggers client.abort(); mid-flight abort rejects with "This operation was aborted" (name === "AbortError") and invokes the instance abort; pre-aborted signal aborts immediately and rejects with AbortError; non-positive timeoutMs creates no request-local timer; abort listener removed and timeout cleared when the signal fires; timeout cleared in finally on success.
  • createMessage abort signal: pre-aborted external signal -> stream rejects with name === "AbortError"; mid-flight external abort -> per-request client abort() is invoked and the in-flight stream rejects with name === "AbortError".
  • Per-request client creation: a fresh Ollama client per completePrompt call; API key passed through the constructor headers option; no headers when no API key is configured; custom baseUrl honored.

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

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Ollama requests now respond to cancellation and timeouts during model discovery and chat, including streaming responses.
    • Cancellation errors are preserved, and request resources are cleaned up when requests complete, are cancelled, or time out.
    • API keys are sent only to HTTPS and local loopback endpoints; remote HTTP requests omit them.
    • Local authenticated requests bypass HTTP proxies.
    • Ollama reasoning content and tool-result images are handled correctly.

Walkthrough

Ollama now creates a client per request and restricts API-key headers to HTTPS and loopback endpoints. Streaming and single-shot requests handle abort signals, timeouts, and cancellation during model discovery. Tests cover cancellation, endpoint security, reasoning parsing, and system-prompt ordering. Vitest development dependencies were updated.

Changes

Ollama request lifecycle

Layer / File(s) Summary
Secure endpoint credential handling
src/api/providers/fetchers/ollama.ts, src/api/providers/fetchers/__tests__/ollama.test.ts
Endpoint checks accept HTTPS and loopback hosts. Model discovery omits API keys for remote HTTP endpoints and disables proxying for credentialed loopback HTTP requests. Tests cover endpoint validation, authorization, and proxy settings.
Request-local clients and streaming cancellation
src/api/providers/native-ollama.ts, src/api/providers/__tests__/native-ollama.spec.ts, src/eslint-suppressions.json
Native Ollama creates a client per request and combines request and SDK signals in fetch. Streaming handles cancellation during model discovery and chat, preserves AbortError, and cleans up listeners and controllers. Tests cover reasoning tags, system-prompt ordering, and cancellation.
Single-shot completion cancellation
src/api/providers/native-ollama.ts, src/api/providers/__tests__/native-ollama.spec.ts
completePrompt handles external abort signals and positive timeouts. It races model discovery against cancellation, preserves AbortError, and clears timers and listeners. Tests cover cancellation and cleanup.

Merge Risk: ⚪ Minimal · up to d9508

Streaming and single-shot cancellation now reach their requests, credentials are gated to secure endpoints, and the Vitest dependency updates match the lockfile. No actionable merge-blocking risk remains.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d9508

The reviewed changes appear to improve request isolation and prevent API keys from being sent to remote plaintext endpoints. No material security regression was established, but the shared credential change can affect existing Ollama configurations.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The credential-policy change applies to configured Ollama requests and to model discovery through the shared fetcher. The inspected paths do not show a change to other provider credentials or an expansion of the provider's authority.

Trust Boundaries and Controls

  • observed — A configured endpoint crosses the network credential boundary only when the shared predicate accepts it; both native client construction and model discovery apply that gate before attaching Authorization.

Resilience and Maintainability Implications

  • inferred — Request-local clients and transport signals reduce the risk that aborting one Ollama request cancels another. The source also provides cancellation to discovery and preserves identifiable abort errors on completion; live concurrent-request behavior was not observed.

Full details: Regression Evidence

Explanation

Focused regression coverage is incomplete. completePrompt independently guards its new timer with timeoutMs > 0 (native-ollama.ts:689), but the test named “non-positive timeoutMs” checks only 0 (native-ollama.spec.ts:1025-1036); a negative value can regress without detection. The new endpoint-security helper is tested for HTTP, HTTPS, remote HTTP, and malformed URLs, but not unsupported schemes. Its current fall-through accepts a loopback host for schemes such as ftp: (ollama.ts:78-88), so the missing negative case also leaves a credential-gating regression exposed.

Resolution

Add a parameterized provider-level test for timeoutMs values 0 and a negative value, and assert that neither starts a timer. Add lowest-layer tests for ftp:/other non-HTTP schemes on loopback and remote hosts. Update isSecureOllamaEndpoint to require https: or http: before applying the loopback-host rule, then assert that unsupported schemes omit API-key headers.

Full details: Lifecycle Resource Cleanup

Explanation

Changed cancellation paths retain lifecycle resources. raceWithAbortSignal adds an abort listener at src/api/providers/native-ollama.ts:52-64, but its abort handler only rejects. It removes the listener only when pending later settles. If model discovery remains pending after cancellation, as exercised by the changed discovery test at native-ollama.spec.ts:1085-1112, the listener remains attached indefinitely and the pending request continues in the background. completePrompt also creates an AbortSignal.timeout() through mergeAbortSignalAndTimeout() at native-ollama.ts:724, while it already creates a cancellable setTimeout at lines 689-693. The finally block clears only timeoutId at line 751. Therefore, a successful request with a positive timeoutMs leaves the native timeout timer scheduled until its deadline.

Resolution

Make raceWithAbortSignal remove its listener in the abort handler before rejecting, with shared idempotent cleanup for resolve, reject, and abort paths. In completePrompt, use requestController.signal for discovery because the existing timeoutId already aborts that controller, or provide a genuinely cancellable merged-signal implementation. Ensure the timeout resource is cleared when the request settles, including successful completion and external cancellation. Add tests that assert listener removal when abort wins and that no timeout remains after a successful request.

Preserve AbortError on the streaming path.

completePrompt rethrows AbortError unchanged so callers can detect cancellation by name === "AbortError" (Line 630). The streaming path does not do this. If client.abort() fires after the stream starts, the SDK rejects the iterator with an AbortError, and Line 536 wraps it into a generic Error. The name is lost, so callers cannot distinguish cancellation from a transport failure.

The existing test at src/api/providers/__tests__/native-ollama.spec.ts Lines 1929-1972 rejects the client.chat(...) promise, which is caught by the outer handler at Line 538 and rethrown unchanged. It does not cover a rejection raised while iterating the stream.

Rethrow AbortError unchanged in the inner catch, and add a test that aborts after the first chunk is yielded.

🐛 Proposed fix: keep abort identity in the stream catch
 			} catch (streamError: any) {
+				if (streamError instanceof Error && streamError.name === "AbortError") {
+					throw streamError
+				}
 				console.error("Error processing Ollama stream:", streamError)
 				throw new Error(`Ollama stream processing error: ${streamError.message || "Unknown error"}`)

Use !== undefined for the timer check.

Line 635 tests truthiness. Line 605 tests timeoutId !== undefined for the same variable. Align the two checks. A timer id of 0 is valid in the DOM typing and in the test mock at src/api/providers/__tests__/native-ollama.spec.ts Line 833, and truthiness would skip the cleanup for it.

Prefer Vitest fake timers over manual setTimeout spies.

Three tests replace the global setTimeout and clearTimeout and never restore them inside the test. If restoreMocks is not enabled in the Vitest config, the stubs stay active for the rest of the file.

vi.useFakeTimers() with vi.advanceTimersByTime(...) covers the same behavior. It removes the as unknown as typeof setTimeout casts at Lines 834 and 959, and vi.useRealTimers() in afterEach restores the globals deterministically.

As per coding guidelines: "Avoid as any; use typed APIs ... Use double assertions only as a last resort and explain them with a comment."

Complete cancellation handling for createMessage.

If the signal aborts while Line 420 awaits fetchModel(), client.abort() has no active stream to abort. The method does not re-check the signal before starting client.chat(). Also, an AbortError raised during stream iteration is wrapped at Line 536, so callers cannot identify cancellation. Ollama 0.6.0 tracks abortable requests only after a streaming request starts. (raw.githubusercontent.com)

Move model discovery inside the outer try, re-check externalAbortSignal.aborted after it, and rethrow AbortError unchanged from the stream-processing catch. This also ensures the listener cleanup covers model-fetch failures. Add focused tests for abort-during-model-fetch and abort-during-stream behavior.

Series follow-up flag: adopt RequestConfigBuilder for abort/timeout option construction

This PR currently builds its abort/timeout request options directly with mergeAbortSignalAndTimeout(...) from src/api/providers/utils/abort-signal.ts. That is behaviorally identical to the RequestConfigBuilder path (src/api/providers/config-builder/request-config-builder.ts, introduced in #1008) - the builder wraps the same utility. The series plan is to make the builder the canonical call site for SDK request-option construction (typed TOptions variants per SDK), so this PR is flagged for that update.

Status: migration in the post-merge adoption PR. The refactor is mechanical (call-site substitution through the builder with a typed TOptions variant) and is deliberately kept out of this PR to preserve its already-green CI and review state.
Abort semantics (pre-abort fail-fast, mid-flight bridging, the timeoutMs > 0 guard, and normalization to AbortError) are pinned by this PR's regression tests and are preserved by the refactor.

Thanks for contributing. This comment tracks the review sequence and the next action.

Current step: Awaiting fresh human maintainer or CODEOWNER approval.

Automated review is complete for the latest commit but does not replace human approval.

Review-state labels are managed by this workflow; do not edit them manually. community-approved is managed the same way — do not add or remove it manually. It signals a fresh community code approval for the current head as an advisory priority only; maintainer review is still required.

Notes on the CI red and the PR-rule cleanup at head 8cb94a5f1:

  • CI red root cause: every job failed at pnpm install --frozen-lockfile — the root vitest devDependency added by this PR was not fully reconciled in pnpm-lock.yaml (the importer entry was hand-added but the snapshot tree was missing). d2d0cbf23 regenerates the lockfile; pnpm install --frozen-lockfile now passes locally.
  • PR-rule audit: the diff previously contained 5 new as unknown as casts (timer fakes in native-ollama.spec.ts). 8cb94a5f1 replaces them with a structurally-complete NodeJS.Timeout handle and a single structural cast each (the ambient setTimeout signature is not directly castable). Local proof: tsc clean, eslint clean, native-ollama.spec.ts 88/88.

Re-requesting review from @edelauna and the code owners.

consistent.

Review comments at @src/api/providers/__tests__/native-ollama.spec.ts:
- Around line 1063-1071: Update the cancellation test around
handler.completePrompt so mockChat rejects with an AbortError after
controller.abort(), and assert that the promise rejects with that error. Keep
the existing listener-removal and clearTimeout assertions.

Review comments at @src/api/providers/native-ollama.ts:
- Around line 44-55: Update raceWithAbortSignal to retain the abort callback
reference and remove that same listener when pending settles, on both
fulfillment and rejection. Add a test verifying the listener handler passed to
addEventListener is the same one passed to removeEventListener.
- Around line 468-471: Update fetchModel to accept an AbortSignal and pass it to
getOllamaModels via its options; pass the request or discovery signal from both
model-discovery call sites while retaining raceWithAbortSignal as a backstop.

282-298: 🔒 Security & Privacy | 🛡️ Detected with Advanced Tier

Bypass configured proxies for credentialed loopback requests. isSecureOllamaEndpoint() permits HTTP loopback endpoints, and _createOllamaClient() attaches the bearer token to them. The native path then uses the extension host’s patched globalThis.fetch, which can apply the configured VS Code proxy. If loopback hosts are not excluded by http.noProxy, the proxy can receive the bearer token over cleartext HTTP. Add an explicit direct transport for credentialed loopback requests, or otherwise enforce proxy bypass before sending the request.

…test peers

- raceWithAbortSignal: remove the abort listener once pending settles
  (resolve and reject), so a reusable caller signal does not accumulate
  one listener per race
- fetchModel: forward the signal to getOllamaModels (both /api/tags and
  /api/show) from the createMessage and completePrompt discovery call
  sites; the race remains the backstop
- spec: the mid-request abort test now asserts the promise rejects with
  AbortError instead of resolving with a stale response; add
  listener-removal tests for raceWithAbortSignal and
  signal-forwarding assertions for both discovery call sites
- align @vitest/coverage-v8 and @vitest/ui (4.1.9) with vitest 4.1.11 in
  the workspace manifests so the peer versions match

Comment thread src/api/providers/__tests__/native-ollama.spec.ts
… the caller's signal (CodeRabbit, R1, Zoo-Code-Org#1299)

The "discovery is cancellable" test only asserted the shape of the
forwarded third argument ({ signal: <any AbortSignal> }), which a
unrelated or never-aborted signal would also satisfy.

Keep mockGetOllamaModels pending, capture the signal forwarded to the
fetcher while discovery is still in flight, assert it is not aborted,
abort the caller's controller, and assert the captured signal becomes
aborted before the request settles (rejecting with AbortError). The
linkage is now observed during execution, not after.

90/90 specs pass; eslint clean (suppressions unchanged).
