File Modes Getting Lost In Software Templates

Expected Behavior

Consider the following repo state:

$ stat -f %A test.sh
755

and the following template

apiVersion: backstage.io/v1beta2
kind: Template
metadata:
  name: bug-report
  title: bug-report
  description: Add bug report
spec:
  owner: test
  type: test

  steps:
    - id: fetch-repo
      name: Fetch repo
      action: fetch:plain
      input:
        url: 'https://github.com/asummers/backstage/tree/master'

    - id: publish
      name: Publish
      action: publish:github:pull-request
      input:
        repoUrl: 'github.com?owner=asummers&repo=backstage'
        title: 'This PR has different file permissions'
        branchName: 'script-perms'
        description: |
          This is a bug

  output:
    links:
      - url: '{{steps.publish.output.remoteUrl}}'
        text: 'Go to PR'

As I am pulling and pushing to same repo, this should result in no changes to the asummers/backstage repo whatsoever.

Current Behavior

What seems to be happening is +x (and possibly other) are being dropped along the way.

Possible Solution

Pass along file modes faithfully.

Steps to Reproduce

Context

This makes using software templates extremely arduous in repos with scripts with manual correction to files.

Your Environment

• NodeJS Version (v12): v14
• Operating System and Version (e.g. Ubuntu 14.04): OSX, Ubuntu 18.04
• Browser Information: N/A

Possibly, but this template seems to use fetch:plain rather than fetch:template so there might be another bug.

Never mind, we didn’t bump the plugin properly.
