[BUG] Relative path not working on master-minion setup with windows minion

[fgionghi]

Description
When using relative path (eg.: {% from './map.jinja' import packages with context %}) in a formula, a windows minion will not cache the file speficied in the relative path (I can't find that file inside C:\salt\var\cache\salt\minion\files\base\formula-name).

Setup

• on-prem machine
• VM (Vmware)
• VM running on a cloud service, please be explicit and add details
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit
• jails if it is FreeBSD

Steps to Reproduce the behavior
We have found this bug using the package formula with the chocolatey state on a windows minion.
We had this pillar:

packages:
  chocolatey:
    wanted:
      prometheus-windows-exporter.install:
        version: '0.16.0'

When we run the command salt skyros.pc.itc.it state.test packages.chocolatey, we get the error:

skyros.pc.itc.it:

ERROR: Minions returned with non-zero exit code

and in the cache folder on the target (C:\salt\var\cache\salt\minion\files\base\packages) the only file is chocolately.sls without any map.jinja.

We tried with different version of salt-minion, with different windows version (win10, win server 2016/2019) and with two different salt-master (same version of salt-master).

When I run salt skyros.pc.itc.it state.test packages in the cache folder on the target machine I have more files (for example the map.jinja) but not all files (the default.yaml is missing). In fact I get multiple errors regarding the default.yaml file, like this:

Additional tests

With every test it's important to have the cache folder on the minion (C:\salt\var\cache\salt\minion\files\base) empty. We use salt skyros.pc.itc.it saltutil.clear_cache.

We tried without chocolatey, so using directly winrepo. My pillar now is:

packages:
  pkgs:
    wanted:
      - prometheus-wmi-exporter

but the problem persist.

We then did other tests to understand if the bug was only related to that formula.
We made a simple formula called "winpackages":
init.sls:

{% from './map.jinja' import packages with context %}
{% for pkg in packages %}
Choco_package_{{ pkg|upper }}_install:
 chocolatey.installed:
     - name: {{ pkg }}
{% endfor %}

map.jinja:

{% set default_packages = salt['grains.filter_by']({
    'Windows': {
        'pkgs': [
           'googlechrome',
      ]
    },
}) %}
{% set packages = salt['pillar.get']('winpackages:pkgs', default=default_packages.pkgs, merge=True) %}

pillar.sls

winpackages:
  pkgs:
    - prometheus-windows-exporter.install

and this is not working, always giving me ./map.jinja not found.

Then we modify the init.sls like this:
init.sls:

{% from 'winpackages/map.jinja' import packages with context %}
{% for pkg in packages %}
Choco_package_{{ pkg|upper }}_install:
 chocolatey.installed:
     - name: {{ pkg }}
{% endfor %}

and this is working.
Our theory is: salt minion is searching ./map.jinja not inside the formula folder, but on the parent folder (C:\salt\var\cache\salt\minion\files\base).

BUT, we did another test:

• I first use the working method (importing using winpackages/map.jinja)
• so I now have all the formula's files chached on the minion (in C:\salt\var\cache\salt\minion\files\base\winpackages we have both map.jinja and init.sls)
• if then we use the first method (importing using ./map.jinja) is now working.
  So our theory is wrong: the salt-minion is not searching in the parent formula (at least when the formula's files are cached).

Expected behavior
Salt minion should understand the relative path specified in the formula and it should cache those formula's file in the minion.

Additional context
We thought it was a bug of the package formula, in particular with the chocolatey state so we opened an issue with the same details here: saltstack-formulas/packages-formula#79 .

I'm having the same issue in v3004. I've been able to workaround it by using:
{% from slspath ~ '/map.jinja' import packages with context %}
