#!/usr/bin/env bash
# update-openproxy.sh — pull latest upstream, rebuild from source, swap the binary in.
#
#   - Tracks upstream quangdang46/openproxy (main) even though origin is your fork.
#   - Fast-forwards when possible; falls back to a merge commit if you have local commits.
#   - Skips the whole rebuild when HEAD is unchanged and the installed binary already
#     matches the last source build (daily no-op is instant).
#   - Restarts the detached server only if it was already running. Data in ~/.openproxy
#     is untouched.
#
# Overridable env: UPSTREAM_URL, UPSTREAM_BRANCH, DEST_BIN
