Cache never hits

Hi there

I’m running a molecule based Ansible role test via Tox, itself installed by pip. Hence trying to cache pip, tox and molecule. The cache never hit. To be sure I ran the job twice in a row with just a space added in the README.

First one

Second one

Here’s the workflow definition

name: Tests

on:
  push:
    tags:
      - "*"

jobs:
  tests:

    runs-on: ubuntu-latest
    strategy:
      matrix:
        python: [3.7]

    steps:
      - uses: actions/checkout@v2

      - name: Setup git credentials
        uses: fusion-engineering/setup-git-credentials@v2
        with:
          credentials: ${{secrets.GIT_CREDENTIALS}}

      - name: Setup Python
        uses: actions/setup-python@v1
        with:
          python-version: ${{ matrix.python }}

      - name: Cache pip
        uses: actions/cache@v1
        id: cache-pip
        with:
          path: ~/.cache/pip
          key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
          restore-keys: |
            ${{ runner.os }}-pip-

      - name: Install Tox
        if: steps.cache-pip.outputs.cache-hit != 'true'
        run: pip install tox

      - name: Cache Tox
        uses: actions/cache@v1
        with:
          path: .tox
          key: ${{ runner.os }}-tox-${{ hashFiles('**/tox.ini') }}
          restore-keys: |
            ${{ runner.os }}-tox-

      - name: Cache Molecule
        uses: actions/cache@v1
        with:
          path: ~/.cache/molecule
          key: ${{ runner.os }}-molecule-${{ hashFiles('**/requirements.yml') }}
          restore-keys: |
            ${{ runner.os }}-molecule-

      - name: Run Tox
        run: tox

And the tox.ini which should be enough to reproduce

[tox]
envlist = molecule
skipsdist = true

[testenv:molecule]
deps =
  ansible-lint
  flake8
  molecule[docker]~=3.0
  netaddr
  requests
  testinfra
  yamllint
passenv =
  HOME
  SSH_AUTH_SOCK
  TERM
  TTY
commands = echo molecule {posargs:test}

👋 @nvivobume This type of behavior is typically caused by the cache scope. Details can be found in issue https://github.com/actions/cache/issues/79 and in the docs. If the docs aren’t clear or you still see the issue, please let me know.

@crane-hiromu Are the two screenshots from different tags? Is the develop branch the default branch for your repo? Two workflows triggered from tags won’t be able to share caches (same scoping issue I mention above), but can read from caches created by your default branch. I would suggest making sure the changes are in the default branch and a workflow is triggered from the default branch to create the cache.

Indeed, I c/ced my “tests.yml” to make a “make_cache.yml” workflow

on:
  push:
    branches:
      - master

# same stuff as my tests.yml workflow, only the "tox" command change a bit to only install the deps

And it works. “make_cache” is really fast, so doesn’t add much overhead on commits
