--- name: git-sync-daemon description: > Manage multiple git repositories with a daemon model (periodic add/commit/pull/push). Use this skill when you need to set up, run, or troubleshoot automated git sync on macOS (launchd) or Linux (systemd), including repo registration and service lifecycle. --- # Git Sync Daemon ## Purpose Provide a reusable, daemon-based git auto-sync workflow: - one repo list file - one daemon process - per-repo lock and independent failure isolation - service management on macOS and Linux ## Files - Engine: `scripts/git_sync_daemon.sh` - Control CLI: `scripts/git_sync_ctl.sh` ## Default Runtime Paths - State dir: `~/.config/git-sync-daemon` - Repo list: `~/.config/git-sync-daemon/repos.conf` - Log file: `~/.config/git-sync-daemon/git-sync-daemon.log` ## Repo Entry Format One line per repo: ```text /absolute/path/to/repo|remote=origin|branch=main|enabled=1 ``` Supported keys: - `remote` (default `origin`) - `branch` (default current branch) - `enabled` (`1/0`, `true/false`, default enabled) ## Quick Start (macOS) ```bash bash scripts/git_sync_ctl.sh init bash scripts/git_sync_ctl.sh add-repo /Users/samwei12/Develop/config bash scripts/git_sync_ctl.sh run-once bash scripts/git_sync_ctl.sh install-launchd bash scripts/git_sync_ctl.sh status ``` ## Quick Start (Linux) ```bash bash scripts/git_sync_ctl.sh init bash scripts/git_sync_ctl.sh add-repo /path/to/repo bash scripts/git_sync_ctl.sh run-once sudo bash scripts/git_sync_ctl.sh install-systemd bash scripts/git_sync_ctl.sh status ``` ## Operations - Add repo: `bash scripts/git_sync_ctl.sh add-repo <path> [branch] [remote]` - Remove repo: `bash scripts/git_sync_ctl.sh remove-repo <path>` - List repos: `bash scripts/git_sync_ctl.sh list-repos` - One cycle now: `bash scripts/git_sync_ctl.sh run-once` - Status/log tail: `bash scripts/git_sync_ctl.sh status` Service lifecycle: - macOS install: `bash scripts/git_sync_ctl.sh install-launchd` - macOS uninstall: `bash scripts/git_sync_ctl.sh uninstall-launchd` - Linux install: `sudo bash scripts/git_sync_ctl.sh install-systemd` - Linux uninstall: `sudo bash scripts/git_sync_ctl.sh uninstall-systemd` ## Production hardening checklist Before enabling daemon mode in production: 1. SSH/auth baseline - Ensure service user can run non-interactive git over SSH to each remote. - Preload host keys (`ssh-keyscan` / [REDACTED_SECRET]) to avoid first-run failures. - Prefer explicit key routing in `~/.ssh/config` (host/user/port/IdentityFile/IdentitiesOnly). 2. Service identity consistency - Install service with the same user that owns repo credentials and git config. - Verify `git config --global user.name/user.email` for that service user. 3. Repo registration policy - Register only clean, intended repos. - Keep one canonical branch per repo entry; avoid detached HEAD targets. - Use `enabled=0` for temporary pauses instead of deleting lines. 4. Observability - Keep logs in dedicated file and rotate externally if needed. - Validate `run-once` before enabling persistent service. ## Safety Notes - The daemon does not force-push. - Rebase conflicts are logged and isolated to the affected repo. - If `git-lfs` is required by hooks but missing, that repo is skipped with explicit error log. - On macOS launchd, PATH is expanded in both service env and daemon script to include Homebrew binaries. - Recommended migration practice: first successful run should use baseline repos only; then gradually add more repos.
