@copilot ci fails

Fixed in aaa230e. I investigated the failing Actions run and updated test/options.dispatcher.test.ts to avoid the flaky external HTTPS path and to close created ProxyAgent instances during teardown, which was causing the suite to hang in CI.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• registry.npmmirror.com
  • Triggering command: /home/REDACTED/.npm/_npx/992a19d7d9bf36d4/node_modules/node/bin/node /home/REDACTED/.npm/_npx/992a19d7d9bf36d4/node_modules/node/bin/node --experimental-import-meta-resolve --require /home/REDACTED/work/urllib/urllib/node_modules/.pnpm/@voidzero-dev+vite-plus-test@0.1.20_@arethetypeswrong+core@0.18.2_@types+node@22.19.17__be9d289fb071b59767ee3a2ed415b245/node_modules/@voidzero-dev/vite-plus-test/suppress-warnings.cjs --conditions node --conditions development /home/REDACTED/work/urllib/urllib/node_modules/.pnpm/@voidzero-dev+vite-plus-test@0.1.20_@arethetypeswrong+core@0.18.2_@types+node@22.19.17__be9d289fb071b59767ee3a2ed415b245/node_modules/@voidzero-dev/vite-plus-test/dist/workers/forks.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot ci fails

Fixed in d2d0156. The current CI failure was a MockAgent regression from the default dispatcher change in HttpClient; default requests now keep urllib’s HTTP/1.1-safe dispatcher unless the global undici dispatcher has been explicitly overridden, so the mocking tests pass again.
