Daemon Management

This skill covers how to manage the lifecycle of the AutomateLinux daemon, specifically focusing on building and restarting it using custom terminal functions.

Core Functions

bd (Build Daemon)

The primary function used to build and restart the daemon. It performs the following:

1. Remembers the current directory.
2. Navigates to the daemon source directory ($AUTOMATE_LINUX_DAEMON_DIR).
3. Calls the bs function.
4. Returns to the original directory.

bs (Build and Source)

An alias for b -source. It triggers the b function with the -source flag.

b (Build Wrapper)

A wrapper for the project's build scripts. When called with -source, it sources the build.sh script instead of executing it in a subshell, allowing environments variables and function definitions within the script to persist if needed.

Daemon Build Process (daemon/build.sh)

When bd is executed, the daemon/build.sh script performs these steps:

1. Stop Service: Executes daemon/stop_daemon.sh to safely shut down any running instances.
2. Environment Check: Ensures the UDS (Unix Domain Socket) directory /run/automatelinux exists and has the correct ownership.
3. Build:
   • Creates/enters the build directory.
   • Runs cmake ...
   • Runs make.
4. Deployment:
   • Copies the newly built daemon binary to the daemon root.
   • Reloads systemd (systemctl daemon-reload).
   • Restarts the daemon.service.

Usage

Simply run bd from any terminal session where the AutomateLinux terminal functions are loaded:

bd

[!NOTE] The bd function is defined in terminal/functions/misc.sh and depends on the AUTOMATE_LINUX_DAEMON_DIR environment variable.
