Format Document not working (autopep8, python, vscode)

Environment data

• VS Code version: 1.36.0
• Extension version (available under the Extensions sidebar): 2019.6.22090
• OS and version: macOS, Mojave 10.14.5
• Python version (& distribution if applicable, e.g. Anaconda): Python 2.7.16
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A
• Relevant/affected Python packages and their versions: autopep8 1.4.4 pycodestyle: 2.5.0
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): Jedi Enabled is “checked” (so, True?)

Expected behaviour

When I run “Format Document”, the file is formatted.

Actual behaviour

When I run “Format Document”, the file is not formatted.

Steps to reproduce:

1. Open a Workspace
2. Open up a Python File in the Workspace
3. Right Click -> Format Document

Current Settings:

User Settings (showing only Python related settings):

{
    .
    .
    .
    "workbench.statusBar.visible": true,
    "files.autoSave": "afterDelay",

}

Extensions:

What I have already tried:

1. Ensured autopep8 is installed correctly to py2.7 : pip2 install --upgrade autopep8
2. The interpreter seems to be correctly pointing to py2.7 too
3. This works: /usr/local/lib/python2.7/site-packages/autopep8.py --max-line-length 60 --in-place --aggressive --aggressive test.py
4. This works too: python -m autopep8 --max-line-length 60 --in-place --aggressive --aggressive test.py
5. autopep8 imported in python interpreter is the same as the one pointing in vscode python.formatting.autopep8Path setting:

$ python

>>> import autopep8
>>> autopep8.__file__

vscode setting:
 "python.formatting.autopep8Path": "/usr/local/lib/python2.7/site-packages/autopep8.py"

1. Uninstalled all extensions, reloaded. Reinstalled all extensions.

• When I had uninstalled all extensions, including Python. On “Format Document”, I got a prompt asking me to choose formatter.
• After reinstalling all extensions, including Python. On “Format Document”, I get no prompt. I’m guessing it is honoring my user settings.

Meanwhile,

$ which python
/usr/local/bin/python

$ python --version
Python 2.7.16

Logs

1. No output in “Output” when I run “Format Document”
2. Console log on Developer Tools on “Format Document”

Not 100% certain this is the same issue, but I am seeing similar behaviour with the yapf formatter - but only in certain sub-directories of a project.

I’ll follow a similar diagnostic procedure to the above in case this turns out to be relevant. Ignore if not.

Workspace settings.json:

{
    "files.exclude": {
        "**/__pycache__": true,
        "**/.pytest_cache": true,
        "**/.mypy_cache": true,
    },
    "python.testing.unittestEnabled": false,
    "python.testing.nosetestsEnabled": false,
    "python.testing.pytestEnabled": true,
    "python.testing.pytestArgs": [],
    "[python]": {
        "editor.formatOnSave": true
    },
    "python.jediEnabled": false,
    "python.formatting.provider": "yapf",
    "python.linting.pylintEnabled": true,
    "python.linting.mypyEnabled": true,
    "python.linting.enabled": true,
    "python.linting.lintOnSave": true,
    "git.ignoreLimitWarning": true
}

Interpreter is set to the relevant pipenv virtual environment correctly in user settings. yapf is installed in this virtual environment is has been used correctly by VSCode in the past:

$ where yapf
C:\Users\someone\.virtualenvs\UAssetExperiment-dd5KH3id\Scripts\yapf.exe

$ python
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import yapf
>>> print(yapf.__file__)
C:\Users\someone\.virtualenvs\UAssetExperiment-dd5KH3id\lib\site-packages\yapf\__init__.py

In both the top-level of the project and most other sub-directories Format Document and format-on-save works without issue.

In my project’s automate module sub-directory however no formatting takes place. There is sadly no format-related output in the Python output window.

The following commands work as expected:

yapf -r -i automate
python -m yapf -i automate/git.py

Issue has been present for at least the last 2-3 days when using the latest Insiders, maybe longer.

Thanks, @DonJayamanne. Could there be some additional checks to catch this issue? Possibly log in console with an error/warning?

Or mention about this in the docs?
