🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Validate the project directory before you delete the stale environment.
_prepare_existing_venv removes the existing environment at Line 138. Line 142 then validates project_dir, and Line 146 resolves uv. If either of those later checks fails, the previous environment is already deleted and no replacement is created.
A stale marker combined with a missing project_subpath therefore destroys a usable environment and returns a failure. Move both validations before the stale-environment cleanup.
🐛 Proposed fix to reorder validation and cleanup
logging.debug(f"Creating virtual environment in {venv_path}")
+ if not project_dir.is_dir():
+ return InstallStatusResult(False, f"Python project directory does not exist: {project_dir}")
+

+ except RuntimeError as e:
+ return InstallStatusResult(False, f"Cannot create virtual environment: {e}")

existing_res = self._prepare_existing_venv(venv_path, python_request, is_pinned)
if existing_res is not None:
return existing_res
-
- if not project_dir.is_dir():
- return InstallStatusResult(False, f"Python project directory does not exist: {project_dir}")
-
- try:
- uv = resolve_uv_bin()
- except RuntimeError as e:
- return InstallStatusResult(False, f"Cannot create virtual environment: {e}")Note that test_matching_marker_keeps_existing_pinned_venv patches subprocess.run but does not patch resolve_uv_bin. After this reordering, that test also needs a resolve_uv_bin patch.
