The google-genai library has a known circular-import bug in its
__init__.py chain:
google.genai/__init__.py:21: from .client import Client
-> from ._api_client import BaseApiClient
-> from .types import HttpOptions
When loaded fresh in a pytest process, the chain collides with
itself and leaves google.genai in a 'partially initialized' state.
Per the user spec (startup_speedup_20260606 spec.md:2.2 Layer 3):
"the app controller should post to test clients or the user
when its threads are warmed up with imports — that way the user
knows 'hey you have the ui first, but now you have all the
functionality.'"
This is exactly what the warmup notification system does.
Phase 2 (commit 1354679e) added the WarmupManager + _io_pool,
and the warmup list (state.toml) already includes 'google.genai'.
The AppController.__init__ submits the warmup jobs to the _io_pool
background thread. When the warmup completes, _warmup_done_event
is set and registered on_warmup_complete callbacks fire.
The previous conftest fix imported 'google.genai' DIRECTLY at
conftest module load. That bypassed the whole notification
mechanism. This commit fixes the oversight:
- Reverts the direct `import google.genai`
- Creates an AppController at conftest load time
- Calls `wait_for_warmup(timeout=60.0)` to block until the
background warmup completes
- google.genai ends up in sys.modules via the warmup's
`importlib.import_module` call (same end state, but now via
the documented mechanism)
The conftest's `from src.gui_2 import App` at line 27 is also
a heavy synchronous import chain that runs in-process. By the
time that line executes, the warmup is already in progress on
the _io_pool. The wait_for_warmup() call after that line ensures
the warmup completes before any test collects.
The AppController is session-scoped (one per pytest process).
If another fixture (e.g. live_gui) creates its own AppController
that also runs warmup, the second controller's wait_for_warmup
returns immediately because the modules are already in
sys.modules.
Cost: 60s timeout worst-case (typically completes in ~3s based on
the baseline measurement). One-time per pytest process.
Earlier alternatives I tried and rejected:
- Direct `import google.genai` in conftest: bypasses the
notification mechanism. User feedback: "you are falling back
to your jank."
- Source-level `genai = _require_warmed('google.genai')` + `.types`:
fails the same way (the library bug is in the PARENT's
__init__.py, not the leaf). The parent's __init__.py never
completes in a fresh process; once it's in the "partially
initialized" state in sys.modules, no caller pattern can fix it.
- Revert the conftest change and skip these tests: not viable,
the tests are real and important.
- Add isolate_workspace autouse fixture in conftest.py.
- Monkeypatch SLOP_CONFIG and preset paths to point to a temporary test directory.
- Update test_history_management.py to use dynamic paths.get_config_path().
- Prevents tests from accidentally reading or modifying the active project.toml or config.toml.
- conftest.py: Include tools.text_editors.vscode in live_gui workspace config
- gui_2.py: Add btn_open_external_editor to _clickable_actions
- test_external_editor_gui.py: Tests for external editor GUI integration
Note: Due to process boundaries (GUI runs in subprocess), full VSCode launch
verification requires manual testing. The test infrastructure verifies config,
command format, and button wiring. Manual verification recommended.
- Add AppController.stop_services() to clean up AI client and event loop
- Add ConfirmDialog, MMAApprovalDialog, MMASpawnApprovalDialog imports to gui_2.py
- Fix test mocks for MMA dashboard and approval indicators
- Add retry logic to conftest.py for Windows file lock cleanup
Applied 236 return type annotations to functions with no return values
across 100+ files (core modules, tests, scripts, simulations).
Added Phase 4 to python_style_refactor track for remaining 597 items
(untyped params, vars, and functions with return values).
