Permission denied when caching macports

[rami3l]

Installing macports is a time-consuming part in my CI, so I guess backing up /opt/local will help:

- name: Cache MacPorts
  id: cache-macports
  uses: actions/cache@v2
  with:
    path: /opt/local/
    key: ${{ runner.os }}-macports-${{ hashFiles('macos_build.txt') }}

However, since #133 didn't accept using sudo tar, I got a long error log all about permissons:

Run actions/cache@v2

Is it possible to introduce some sort of sudo, or is there any workaround?

Thanks in advance!

same problem like you,we need sudo

I've pushed a sudo branch which is available via: uses: john-shaffer/cache@sudo-tar

I was able to work around this issue by creating the following file in my repository as gtar:

#!/bin/sh
exec sudo /usr/local/bin/gtar.orig "$@"

and adding the following step to my job before the cache action:

    - name: "Install gtar wrapper"
      run: |
        sudo mv /usr/local/bin/gtar /usr/local/bin/gtar.orig
        sudo cp macosx/gtar /usr/local/bin/gtar
        sudo chmod +x /usr/local/bin/gtar

@john-shaffer Thanks a lot for your patch!

However, due to the deprecation of save-state, it might stop working at the end of March 2023.

Would you mind checking it out? 🙏

[john-shaffer]

@rami3l you can use uses: john-shaffer/cache@main

Still needed. I installed Racket, which is slow, so I cached it; but I couldn't restore it.
