Conda environment is not activated in current terminal

Environment data

• VS Code version: 1.43.2
• Extension version (available under the Extensions sidebar): 2020.3.69010
• OS and version: Win 10
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.8
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): Conda 4.8.3

Expected behaviour

Conda env should activate in current terminal on load of the extension

Actual behaviour

Conda env does not activate in current terminal on load of the extension, despite "python.terminal.activateEnvInCurrentTerminal": true.

Possible explanation

This is the same as #10782. I thought I had fixed the problem but I was wrong. What I realized is that the extension does not trigger the .../miniconda/Scripts/activate only for environments with very long names. Try for example to create a new Conda environment with

conda create -n this_is_a_very_long_environment_name python

Everything works fine if I use a shorter name.

This particular issue with long conda env names is addressed, and the fix is in master. It will be available in the May release.

Hi. I just figured out that I have this exact same issue. Here are some pointers that might help: Responsible code: https://github.com/microsoft/vscode-python/blob/61b179b2092050709e3c373a6738abad8ce581c4/src/client/interpreter/locators/services/condaHelper.ts#L59

If the name is too long, the split-offset is wrong and part of the name is added to the path:

[
    {
        "name": "base",
        "path": "/home/my_user/miniconda3"
    },
    {
        "name": "hpc-quickstart-inferencin",
        "path": "g     /home/my_user/miniconda3/envs/hpc-quickstart-inferencing"
    }
]

which is expected if you have a look at the output of the “conda env list”-command where the / of the base-path aligns with the g that gets clipped from the path of the other environment:

base                  *  /home/u161040/miniconda3
hpc-quickstart-inferencing     /home/u161040/miniconda3/envs/hpc-quickstart-inferencing

hope this helps.
