[FEATURE REQUEST] Ability to run a command before calculating cache key?

[willhughes-au]

I have a situation where it would be useful to cache data, but the key needs to be a checksum of a file that isn't on the filesystem, yet.

An arbitrary example:

  - label: "Run Cached Step"
    command:
      - wget -O remote-config https://example.com
      - ./script-that-does-something.sh
    plugins:
      - gencer/cache#v2.4.10:
          key: "{{ id }}-{{ checksum 'remote-config' }}"
          paths:
            - .cache-dir

Running the wget command as a separate step won't work, as the file system gets cleaned, and even if there weren't, we run multiple agents.

Would it be possible/make sense to have a pre-run-command argument that I could have, Or perhaps be able to invoke the plugin manually?

Examples:

  - label: "Run Cached Step"
    command:
      - ./script-that-does-something.sh
    plugins:
      - gencer/cache#v2.4.10:
          key: "{{ id }}-{{ checksum 'remote-config' }}"
          pre-restore-command: wget -O remote-config https://example.com
          paths:
            - .cache-dir

or perhaps:

  - label: "Run Cached Step"
    command:
      - wget -O remote-config https://example.com
      - gencer-cache-restore
      - ./script-that-does-something.sh
    plugins:
      - gencer/cache#v2.4.10:
          key: "{{ id }}-{{ checksum 'remote-config' }}"
          defer_restore: true
          paths:
            - .cache-dir

This is probably a very niche/weird request.

This is probably a very niche/weird request.

Normally, Yes. But not in this situation because of:

Running the wget command as a separate step won't work, as the file system gets cleaned, and even if there weren't, we run multiple agents.

Which makes this request meaningful.

There are 3 open requests incl. this one and I still not yet finished any of them. I'll try to implement ASAP. However, I am fully open for PRs (Generally speaking).
