From 564b9a3e087e714fc5725f3b8bfc9cdfefad4497 Mon Sep 17 00:00:00 2001 From: ABHIJEET RANJAN Date: Thu, 11 Jun 2026 17:39:07 +0530 Subject: [PATCH 1/5] fix(inference): shim globalThis.fetch to proxy inference.local for cron preflight MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cron agentTurn jobs using a local Ollama provider were being skipped because the cron scheduler's provider preflight uses fetch() (undici) rather than http.request(), bypassing the OpenShell sandbox proxy that routes the virtual hostname inference.local to the local Ollama instance. The existing http-proxy-fix.js already patches http.request and https.request to honour proxy env variables. The preflight never goes through that path — it calls fetch() directly, which resolves inference.local via raw DNS, gets EAI_AGAIN, and marks the provider unreachable, causing the cron job to be skipped entirely. Extended http-proxy-fix.js to wrap globalThis.fetch for requests whose hostname is inference.local, routing them through the existing proxy-aware path. Every other hostname passes through the original fetch unchanged. The shim is: - Idempotent via __nemoclawFetchPatched guard - A no-op when typeof globalThis.fetch !== 'function' (Node < 18) - Scoped strictly to inference.local via URL hostname parsing - Non-destructive to the existing http.request/https.request patch - Free of hardcoded replacement addresses - Does not modify NO_PROXY or the managed inference.local routing design Also fixed in this commit: - Pre-existing Windows env case collision (HTTPS_PROXY vs https_proxy) in the existing proxy test suite causing false failures on Windows - Bash-dependent sync tests now skip locally when Bash/WSL is unavailable, but fail in CI to catch real regressions Verification: - npm test (proxy-focused suites) passed - npm run typecheck passed - node --check http-proxy-fix.js passed - git diff --check passed Fixes #4730 # Conflicts: # test/http-proxy-fix-sync.test.ts --- nemoclaw-blueprint/scripts/http-proxy-fix.js | 162 ++++++++++++- scripts/nemoclaw-start.sh | 8 +- test/http-proxy-fix-e2e.test.ts | 3 - test/http-proxy-fix-fetch.test.ts | 228 +++++++++++++++++++ test/http-proxy-fix-rewrite.test.ts | 3 - test/http-proxy-fix-sync.test.ts | 130 +++++++---- 6 files changed, 472 insertions(+), 62 deletions(-) create mode 100644 test/http-proxy-fix-fetch.test.ts diff --git a/nemoclaw-blueprint/scripts/http-proxy-fix.js b/nemoclaw-blueprint/scripts/http-proxy-fix.js index 78e663e0924..ad80b24be2c 100644 --- a/nemoclaw-blueprint/scripts/http-proxy-fix.js +++ b/nemoclaw-blueprint/scripts/http-proxy-fix.js @@ -1,10 +1,10 @@ // SPDX-FileCopyrightText: Copyright (c) 2026 NVIDIA CORPORATION & AFFILIATES.
