From c6bc7b38e308271c4da3e2d348622c17a802cb71 Mon Sep 17 00:00:00 2001 From: Ling-Sen Peng Date: Sat, 18 Jul 2026 14:12:13 -0700 Subject: [PATCH] fix(examples): verify example catalog against conductor-oss 3.32.0-rc.8; fix 9 broken examples + worker-tool registry lookup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Full verification run of the example catalog (agents suite: 96 PASS / 46 SKIP / 2 ERROR / 2 HUNG; core suite: 13 PASS / 4 daemon-by-design / 1 interactive) — see examples/VERIFICATION_REPORT.md for status tracking, environment, root causes, and remaining known failures. Example fixes (all verified end-to-end against a live server): - greetings_worker.py: duplicate `def greet` shadowed the registered worker and broke spawn pickling on macOS/Windows (workers_e2e, helloworld, task_listener_example) - worker_example.py: hardcoded /Users/viren metrics dir -> tempfile - user_workers.py: import via examples.* package identity crashed spawn children that load the module as user_example.* - kitchen_sink.py: @agent classifier functions must take zero args - 16i/16j: tools defined inside factory functions are not importable by spawn workers (SpawnSafetyError) — hoisted to module level - 94_openai_runner_tools.py: keep the plain function at module level and apply function_tool() at Agent construction so the module global is not rebound to an unpicklable FunctionTool - llm_chat.py: server requires a non-empty user message (two tasks sent system-only lists); also exit non-zero when the workflow ends FAILED instead of reporting success on any terminal state - run_all_examples.py: classify 6 env-dependent examples as SKIP with reasons (dg skill repo; workflow messages API absent in rc.8) SDK fix: - tool.py _try_worker_task: registry identity check failed once ToolRegistry.register_tool_workers re-registered the task name with a spawn-safe ToolWorkerEntry wrapper; lookup now walks __wrapped__ / fn_direct / fn_ref carriers (broke 14_existing_workers.py; 2 regression tests added, tests/unit/ai: 1744 passed) Docs: - examples/agents/README.md + examples/README.md: agent examples require conductor-oss >= 3.32.0-rc.8 (`conductor server start --version 3.32.0-rc.8`); the CLI's `latest` (3.30.x) has no /api/agent/* and fails with AgentNotFoundError HTTP 404. Also fixed the provider/model table (OpenAI row showed the Anthropic default string).

Broke + `14_existing_workers.py`. The lookup now walks `__wrapped__` chains and the + wrapper's `fn_direct`/`fn_ref` carriers.

Tools hoisted to module level; both now pass. + +7. **`examples/agents/94_openai_runner_tools.py` — `@function_tool` rebinding.** The + decorator rebinds the module global to a `FunctionTool`, so the extracted original + couldn't be pickled by reference.
