Python 3.12.4

Describe the issue:

On a Workbench server that doesn't have Python on the PATH, try to create a new Project with a version of Python in /opt/python but not on PATH. Note that the versions in /opt/python are not discovered

Steps to reproduce the issue:

Expected or desired behavior:

Were there any error messages in the UI, Output panel, or Developer Tools console?

This is related to #4270. The Project Wizard only includes Pyenv and Global interpreters in this dropdown. I think Python versions not on the PATH have runtime source Unknown, which is not included in this dropdown.

positron/src/vs/workbench/browser/positronNewProjectWizard/interfaces/newProjectWizardEnums.ts

Lines 39 to 45 in 0108e50

	/**
	* PythonRuntimeFilter enum.
	*/
	export enum PythonRuntimeFilter {
	Global = 'Global',
	Pyenv = 'Pyenv'
	}

We probably want to create a new command in the Python extension that checks if a given interpreter path is for a global Python installation, and display the interpreter in the Project Wizard interpreter dropdown based on the result. We currently make the runtime filtering decision in the Project Wizard, which currently only recognizes Pyenv and Global runtime sources as "Global" python installations.

On one of our internal instances, I do now see Python 3.12.4 on PATH as Global and it's on the New Project flow 🎉

There still appears to be some lag between overall discovery and this version being made available on the New Project flow, eg if I quickly start a session and try to create a New Project, the Python on PATH may be temporarily excluded.

QA Notes

Unknown runtimeSource interpreters should now show in the Project Wizard interpreter dropdown.

I'm not seeing this anymore in 2024.12.0-96
