Python distribution

python.org

Python version

Expected behaviour

As I updated Python extension to todays version, v2021.11.1422169775, in today’s updated VSCode 1.62.0, I switched to the ‘Extensions’ panel and its “Changelog” tab.

Actual behaviour

I got the title error in statusbar:

The Python Tools server crashed 5 times in the last 3 minutes. The server will not be restarted.

I also notice high cpu usage during that time.

Steps to reproduce

Simply open VSCode, without opening any specific folder, and open the ‘Extensions’ panel and its “Changelog” tab.

Here is a screen capture to show what I mean:

[karthiknadig]

defaultInterpreterValue is not updated by selecting python interpreters for the selector. It has to be manually set. As the description suggests we use it as a fall back if nothing is selected for a given workspace.

[darkred]

we should probably update the text for defaultInterpreterValue to let users know that it has to be manually set.

Updating the description would be useful, but I hope there’s more room for improvement:

The python.defaultInterpreterPath description is as follows:

Path to Python, you can use a custom version of Python by modifying this setting to include the full path. This default setting is used as a fallback if no interpreter is selected for the workspace. The extension will also not set nor change the value of this setting, it will only read from it.

My suggestion is, if possible, to make the extension validate the python.defaultInterpreterPath value (=whether it points to an existing python.exe executable or it’s just python, or it’s invalid). And additionally, when first/clean installing the extension, to have a default/initial value (maybe python or to be just empty).

I am suggesting this because, currently, this setting works as if it’s a setting of VSCode itself and not of an extension, which is not the case. And, as it is (i.e. that the extension doesn’t set nor change its value, but only reads it), if for some some reason it gets an invalid value, or its value becomes invalid after uninstalling some old Python version (like it occurred to me), it will permanently get stuck with that wrong value until the user manually sets it (or resets it to python).
