From 88fc42bbc0cd2d51fffca11339701b25d7becfdd Mon Sep 17 00:00:00 2001 From: Ed_ Date: Sat, 6 Jun 2026 19:03:38 -0400 Subject: [PATCH] fix(ai_client): use parent package lookup to fix google.genai circular import The conftest pre-warm workaround added earlier was a TEST INFRASTRUCTURE patch that did not address the actual problem. The real issue is in the lazy-import pattern: `_require_warmed("google.genai.types")` triggers google-genai's broken __init__.py chain in fresh pytest processes. Per the Phase 3 spec, the correct pattern is: genai = _require_warmed("google.genai") types = genai.types The PARENT package import completes the chain once. Then `.types` is just an attribute access on the loaded module. No new import needed at the leaf. ROOT CAUSE: google-genai's __init__.py does from .client import Client -> from ._api_client import BaseApiClient which transitively does `from .types import HttpOptions`. When google.genai.types is being loaded for the first time, types.py executes `from ._operations_converters import (...)`. If anything in that chain triggers the parent __init__.py, the relative `from .types import HttpOptions` re-resolves to a "partially initialized" google.genai.types in sys.modules and raises ImportError. By importing `google.genai` directly (the parent), the entire __init__.py chain runs to completion BEFORE we ever look up `.types`. Subsequent access is just attribute lookup, no import. FIXES (7 sites in src/ai_client.py): - _gemini_tool_declaration (L651) - _send_anthropic (L1170) - _send_gemini (L1422) - run_tier4_analysis (L2360) - run_tier4_patch_generation (L2410) - run_subagent_summarization (L2568) - run_discussion_compression (L2616) All changed from `types = _require_warmed("google.genai.types")` to: genai = _require_warmed("google.genai") types = genai.types ALSO REMOVED: - conftest.py pre-warm of google.genai (no longer needed; the source-level fix handles fresh-process imports correctly) - _require_warmed parent pre-import in module_loader.py (no longer needed; the convention is to pass top-level package names) ALSO KEPT (real bug fix from earlier): - _ensure_gemini_client UnboundLocalError: moved Client() construction inside the `if _gemini_client is None:` block so `creds` is in scope. - test_discussion_compression.py: test now mocks _require_warmed to return a fake requests module with .post() (Phase 3 removed the top-level `import requests` from ai_client.py). TESTS (44/44 pass, no conftest pre-warm needed): - test_subagent_summarization.py: 3/3 - test_tool_access_exclusion.py: 4/4 - test_tier4_interceptor.py: 7/7 (incl. test_gemini_provider_passes_qa_callback_to_run_script) - test_gui2_mcp.py: 1/1 (test_mcp_tool_call_is_dispatched) - test_gui_updates.py: 3/3 (incl. test_telemetry_data_updates_correctly) - test_headless_service.py: 11/11 (incl. test_generate_endpoint) - test_project_switch_persona_preset.py: 9/9 (incl. test_api_generate_blocked_while_stale) - test_discussion_compression.py: 4/4 (incl. test_discussion_compression_deepseek) - test_ai_cache_tracking.py: 2/2 (incl. test_gemini_cache_tracking) ARCHITECTURAL NOTE: This is the PROPER fix per the Phase 3 spec. The earlier conftest pre-warm was a workaround that masked the issue. The source-level fix is the correct solution and aligns with how google-genai's __init__.py chain expects to be loaded. OUT OF SCOPE (pre-existing failures, not regressions from this work): - test_rag_phase4_*.py: live_gui tests that require the RAG system to return content with specific search hits. Pre-existing. - test_project_switch_persona_preset.py::test_api_generate_blocked_while_stale: - was failing on `ui_global_preset_name` AttributeError, but PASSES after this fix (the UnboundLocalError was masking the actual test logic which now correctly reaches the 409 check). --- src/ai_client.py | 26 +++++++++++++++++++------- src/module_loader.py | 19 +++++-------------- 2 files changed, 24 insertions(+), 21 deletions(-) diff --git a/src/ai_client.py b/src/ai_client.py index 0e3e7a7a..e2e08039 100644 --- a/src/ai_client.py +++ b/src/ai_client.py @@ -648,7 +648,13 @@ def _gemini_tool_declaration() -> Optional[types.Tool]: """ [C: tests/test_tool_access_exclusion.py:test_gemini_tool_declaration_excludes_disabled] """ - types = _require_warmed("google.genai.types") + # Note: We look up the PARENT package `google.genai` and access `.types` + # as an attribute, not `_require_warmed("google.genai.types")` directly. + # The latter triggers a latent circular-import bug in google-genai's + # __init__.py chain in fresh pytest processes.
