firestorm/build-env/sync-from-windows.sh

#!/usr/bin/env bash
# sync-from-windows.sh
# Pulls build and deploy OUTPUTS back from the Windows build/test machine
# mounted at /vwe/firestorm. This is the inverse of sync-to-windows.sh, which
# pushes sources out.
#
# Only GENERATED artefacts come back. Source, content and assets are never
# pulled, so local edits made since the last push cannot be clobbered by a
# stale copy sitting on the build machine.
#
# Usage:
#   ./sync-from-windows.sh            # pull everything generated
#   ./sync-from-windows.sh --dry-run  # preview only, no files written
#   ./sync-from-windows.sh --delete   # also delete local files that are gone
#                                     # on Windows (off by default: a pull with
#                                     # --delete can destroy mirrored history)
#
# This repo is a full disaster-recovery mirror -- build outputs are tracked on
# purpose (.gitignore is deliberately almost empty), so pulling them back and
# committing them is the intended workflow, not noise.

# Deliberately NOT -a: the CIFS mount reports every file as 755 while git
# tracks these as 100644. Preserving permissions would flip the exec bit on
# every file pulled and show up as a mode change on thousands of paths.
# -rlt keeps recursion, symlinks and mtimes; --chmod forces sane local modes.
