# Builds a cached .tar.gz of the master branch with full history and
# uploads it to Google Cloud Storage. This archive is downloaded by a
# script defined by a CI/CD variable named CI_PRE_CLONE_SCRIPT. This has
# two benefits:
#
# 1. It speeds up builds. A 800 MB download only takes seconds.
# 2. It significantly reduces load on the file server. Smaller deltas
# means less time spent in git pack-objects.
#
# Since the destination directory of the archive depends on the project
# ID, this is only run on GitLab.com.
#
# CI_REPO_CACHE_CREDENTIALS contains the Google Cloud service account
# JSON for uploading to the gitlab-ci-git-repo-cache bucket. These
# credentials are stored in the Production vault.
#
# Note that this bucket should be located in the same continent as the
# runner, or network egress charges will apply:
# https://cloud.google.com/storage/pricing
