fix: CI green — all Python versions (3.12 – 3.14t): pytest, persistence, cffi, voyageai by Copilot · Pull Request #276 · knitli/codeweaver

Copilot · 2026-03-24T21:36:30Z

CI was failing across all Python versions. This PR fixes every root cause identified through iterative CI runs.

Root causes & fixes

`pytest` not found (Python 3.12, 3.14, 3.14t)

uv run pytest was recreating the venv for non-default Python versions and only installing production deps — dropping the test dependency group and with it pytest.

mise.toml — test-cov task:

- uv run pytest tests/ --cov=codeweaver ...
+ uv run --group test pytest tests/ --cov=codeweaver ...

Wrong Python version in `cloud-setup` venv

cloud-setup was referencing MISE_PYTHON (undefined → always defaulted to 3.13) instead of PYTHON_VERSION. Note: MISE_PYTHON_VERSION and PYTHON_VERSION intentionally differ to handle free-threaded Python — mise uses the base version while PYTHON_VERSION carries the full specifier used to inform venv creation.

- uv venv ... --python {{ get_env(name='MISE_PYTHON', default='3.13') }} .venv
+ uv venv ... --python {{ get_env(name='PYTHON_VERSION', default='3.13') }} .venv

Persistence errors in real-provider tests (Python 3.12 & 3.13)

MemoryVectorStoreProvider had two related problems that together caused .tmp-path failures during long-running real-provider tests:

persist_interval=None in MemoryConfig is documented as "disable periodic persistence", but the code normalised any None to a hardcoded 300 seconds, making it impossible to opt out via config.
_default_memory_config() hardcodes auto_persist=True, which bypassed the test-environment guard in _init_provider (the guard only fired when auto_persist was None). This left handle_persistence() calling _persist_to_disk() after every upsert. Concurrent calls then raced on the shared .tmp directory — producing FileNotFoundError (3.12) and OSError: Directory not empty (3.13).

inmemory.py — distinguishes a missing persist_interval key from an explicit None, uses DEFAULT_PERSIST_INTERVAL (600 s) instead of the hardcoded 300, and always disables persistence in test mode regardless of the config value:

- persist_interval = self.config.in_memory_config.get("persist_interval")
- if persist_interval is None:
-     persist_interval = 300
+ in_memory_config = self.config.in_memory_config
+ if "persist_interval" not in in_memory_config:
+     persist_interval = DEFAULT_PERSIST_INTERVAL   # 600 s
+ else:
+     persist_interval = in_memory_config.get("persist_interval")  # None = disabled

- if auto_persist is None:
+ if auto_persist is None or is_test_environment():
      auto_persist = not is_test_environment()

- if auto_persist:
+ if auto_persist and persist_interval is not None and not is_test_environment():
      periodic_task = asyncio.create_task(self._periodic_persist_task())

The or 300 fallback in _periodic_persist_task is also replaced with DEFAULT_PERSIST_INTERVAL.

`cffi` build failure (Python 3.13t) — `permit-fastmcp` in optional extras

permit-fastmcp has a cffi transitive dependency that cannot be built on free-threaded Python 3.13t. It appeared twice (duplicate) in both full and full-gpu extras with no python_version guard, causing uv sync --extra full (which test-cov depends on via sync) to fail before any tests ran.

pyproject.toml — mirrors the existing azure-key-vault exclusion pattern; also removes duplicate entries and applies the same guard to full-gpu which was missing it:

- "permit-fastmcp",
- "permit-fastmcp",   # duplicate
+ "permit-fastmcp; python_version != '3.13'",

And in full-gpu, the unguarded pydantic-settings[azure-key-vault] is also corrected to match the split already present in full:

- "pydantic-settings[yaml,toml,aws-secrets-manager,azure-key-vault,gcp-secret-manager]",
+ "pydantic-settings[yaml,toml,aws-secrets-manager,gcp-secret-manager]; python_version == '3.13'",
+ "pydantic-settings[yaml,toml,aws-secrets-manager,gcp-secret-manager,azure-key-vault]; python_version != '3.13'",

`cffi` build failure (Python 3.13t) — `twine` in `build-system.requires`

twine was incorrectly placed in [build-system].requires. It is a publishing tool, not a build tool, and has no role there. When uv generates editable-install metadata for the package it installs the build-system requirements; twine → cryptography → cffi 2.0.0, and cffi 2.0.0 explicitly refuses to build on free-threaded Python 3.13. Removed twine from build-system.requires (it remains in the build dependency group):

 [build-system]
 requires = [
   "hatchling>=1.29.0",
-  "twine>=6.2.0",
   "uv-dynamic-versioning>=0.13.0",
 ]

`voyageai` has no distribution for Python 3.14+ (Python 3.14, 3.14t)

voyageai==0.3.7 was in [project.dependencies] without a python_version guard. Voyageai 0.3.7 has no distribution for Python 3.14+, causing package installation to fail entirely on those versions.

pyproject.toml — added ; python_version < '3.14' to the core dependency and to the recommended and voyageai optional extras:

-  "voyageai==0.3.7",
+  "voyageai==0.3.7; python_version < '3.14'",

Summary by Sourcery

Fix CI test execution issues across Python versions and prevent background persistence from running during tests.

Bug Fixes:

Ensure the cloud-setup virtual environment uses the Python version specified by PYTHON_VERSION instead of an undefined MISE_PYTHON variable.
Run pytest under uv with the test dependency group so pytest is available in non-default Python version environments.
Disable the periodic in-memory vector store persistence task when running in test environments to avoid FileNotFoundError during long-running tests.

…ests 1. mise.toml: Fix cloud-setup using wrong env variable MISE_PYTHON (should be PYTHON_VERSION) for venv creation. This caused wrong Python version for non-3.13 CI jobs. 2. mise.toml: Add --group test flag to uv run pytest in test-cov task. When uv recreates the virtual environment for non-default Python versions (3.12, 3.14), it was only installing production deps, not the test group. This caused pytest to not be found. 3. inmemory.py: Prevent periodic persistence task from starting in test environments. The actual_vector_store fixture uses auto_persist=True from the default config, and the periodic task was firing after 5 min during long real-provider tests, causing FileNotFoundError for the .tmp persist path.

Ensure uv test runs install and use the test dependency group so pytest is available across Python versions.	Update the test-cov task to invoke uv with the test dependency group when running pytest on Unix-like systems. Mirror the same uv invocation change for the test-cov task on Windows.	`mise.toml`
Make the cloud-setup virtualenv honor the requested Python version instead of an undefined env var that always falls back to 3.13.	Replace the MISE_PYTHON environment variable reference with PYTHON_VERSION when selecting the Python interpreter for the uv-created venv. Keep the default Python fallback at 3.13 to preserve current behavior when PYTHON_VERSION is unset.	`mise.toml`
Prevent periodic background persistence from running in test environments to avoid FileNotFoundError during long-running tests.	Gate the creation of the periodic persistence task on both auto_persist being enabled and not running in a test environment.

Hey - I've left some high level feedback:

The change to gate _periodic_persist_task on is_test_environment() alters runtime behavior only in tests; consider instead making the persist path or interval configurable for tests so that the production behavior remains fully exercised under test with a safe location.
Now that cloud-setup uses PYTHON_VERSION instead of MISE_PYTHON, double-check other tasks/scripts that may still rely on MISE_PYTHON for consistency or remove that variable entirely to avoid confusion.

To be clear on the PYTHON_VERSION behavior, we use the difference to resolve an issue with mise and free threaded python. Free threaded python isn't supplied by mise to avoid the issue, so it's important that the MISE_PYTHON vs PYTHON env variables keep their separate behavior because we use the one to inform the other.

+        # Set up periodic persistence if configured (disabled in test environments)
+        if auto_persist and not is_test_environment():
            periodic_task = asyncio.create_task(self._periodic_persist_task())


persist_interval is documented as "set to None to disable periodic persistence", but _init_provider() currently normalizes None to 300 and then unconditionally starts _periodic_persist_task() when auto_persist is truthy. This makes it impossible to disable periodic persistence via config. Consider distinguishing between a missing key vs an explicit None (e.g., check 'persist_interval' in in_memory_config) and only creating the periodic task when the effective interval is not None.

Fixed in 4a87756. _init_provider now distinguishes between a missing persist_interval key (uses DEFAULT_PERSIST_INTERVAL = 600s) and an explicitly set None (disables periodic persistence entirely). The hardcoded 300 fallback is also gone from _periodic_persist_task. The periodic task only starts when auto_persist=True, persist_interval is not None, and not in a test environment.

Reviewer's note: This issue we encountered with another auth provider on 3.13T before; we need to remove permit-fastmcp from the full package for 3.13 in pyproject.toml and make sure nothing else is pulling in cffi for 3.13:
