git-restore-mtime action

A GitHub Workflow Action which restores timestamps of files in the current tree based on their last commit times. Uses the git-restore-mtime script (v2022.12 release) by @MestreLion.

Usage

The sample workflow below illustrates a static site build and deploy using the S3 Sync Action. The aws s3 sync command relies on having the correct timestamps for the files to be uploaded, thus, we must reset them before running that action.

NOTE: git-restore-mtime uses the ref log to find the correct timestamp for each file. This requires a full git history. See checkout dist task in the example below.

name: Build and Deploy

  push:
    branches:
      - master

    steps:
    - name: checkout

    # Note: This is *only* for the very next step, it is not required by
    # git-restore-mtime-action.

    # Run the build script which populates the ./dist folder
    - name: build

        # for each file. This requires a full git history. The default value (1)
        # creates a shallow checkout.
