To Reproduce

1. Uninstall asdf v0.15
2. Migrate to asdf v0.16.0 by following the Upgrading to 0.16.0 documentation
3. Install the asdf python plugin
4. Run the command asdf list all python

Describe the Bug

Running asdf list all python returns no output.

$ asdf list all python

$

Expected Behaviour

Running "asdf list all python" should return the list of all python versions available for installation.

[DevL]

After otherwise configuring asdf according to the upgrade guide, I got this working by removing and then adding the asdf Python plugin again. I can only assume that by reinstalling the plugin, a working version of the underlying pyenv repo was cloned and used.

asdf plugin remove python
asdf plugin add python
asdf list all python

[kurone-kito]

asdf plugin remove python
asdf plugin add python
asdf list all python

The commands helped me, but I had to run it every time I ran the following: asdf plugin update --all

Not a stable solution. It works on one laptop and never works on another same-type laptop.

Would be happy to have a permanent solution.

Synopis and workaround

Running asdf plugin update python (or asdf plugin update --all) deletes everything in $ASDF_DATA_DIR/plugins/python/pyenv/, except the .git folder. This is a symptom of https://github.com/asdf-vm/asdf/issues/1948. The following workaround restores the contents of the pyenv/ directory:

git -C "$ASDF_DATA_DIR/plugins/python/pyenv/" restore .

Steps to reproduce the problem

Setup the environment

asdf plugin add python                          # [✓] status code 0
asdf list all python | wc -l                    # [✓] prints 912
asdf install python 3.10.16                     # [✓] status code 0
asdf list all python | wc -l                    # [✓] prints 912
~/.asdf/plugins/python/bin/list-all             # [✓] prints space-separated list of python versions
~/.asdf/plugins/python/bin/list-all | wc -c     # [✓] prints 13777
~/.asdf/plugins/python/pyenv/plugins/python-build/bin/python-build --definitions | wc -l    # [✓] prints 911

Trigger the problem

asdf plugin update python       # triggers the bug. the call returns status code 0.
                                # after this line, calls to "asdf list all python"
                                # print an empty line.

Show the problem

asdf list all python | wc -l    # status code 0. I expected it to print 912, but got 1.

Explore the problem

~/.asdf/plugins/python/pyenv/plugins/python-build/bin/python-build --definitions
    # returns status code 127.
    # Prints:
    # -bash: /Users/mariano/.asdf/plugins/python/pyenv/plugins/python-build/bin/python-build: No such file or directory

find ~/.asdf/plugins/python/pyenv
    # Shows that the directory contains a single ".git" directory.

git -C ~/.asdf/plugins/python/pyenv status
    # Reveals that all files in the directory were deleted


git -C ~/.asdf/plugins/python/pyenv restore .
    # Restores the deleted files

~/.asdf/plugins/python/pyenv/plugins/python-build/bin/python-build --definitions
    # returns status code 0
    # prints the list of python versions

Thanks @marianopeterson , your workaround fixed the issue for me.

I've corrected the issue reported in https://github.com/asdf-vm/asdf/issues/1948 with PRs https://github.com/asdf-vm/asdf/pull/1995 and https://github.com/asdf-vm/asdf/pull/1998. asdf is back to using the CLI git client for management of plugin repositories. This should no longer be an issue for anyone running asdf plugin update python, however, anyone who did run asdf plugin update python from a version of asdf containing the bug will need to use your workaround @marianopeterson to get the issue fixed, or re-install the plugin completely. I'm going to close https://github.com/asdf-vm/asdf/issues/2016 and refer everyone to this issue for the fix.
