Improved error handling, but consider enhancing the exception chaining.
The addition of error handling for the conda info command is a good improvement. It provides a more informative error message when conda is not installed or accessible. However, there's an opportunity to enhance the exception handling further.
Consider modifying the exception raising to use exception chaining. This will preserve the original exception's traceback, which can be helpful for debugging. Here's a suggested improvement:
try:
self.info = json.loads(
shell.check_output(self._get_cmd("conda info --json"), text=True)
)
except subprocess.CalledProcessError as e:
- raise WorkflowError(
- "Error running conda info. "
- f"Is conda installed and accessible? Error: {e}"
- )
+ raise WorkflowError(
+ "Error running conda info. "
+ f"Is conda installed and accessible?"
+ ) from eThis change addresses the static analysis hint (B904) and provides better context for debugging by preserving the original exception information.
