This change adds logic to block signals on child threads. This is done
so that we can migrate signal handling to the main thread, even if we
add additional threads in the future.
When running in foreground, it is likely that it is running within
systemd. In this case, a stale PID file is likely to have a PID that
corresponds to a different process, which can still be kill'ed by the
root user. This results in a false positive that the process is still
running and causes the daemon to abort prematurely.
Fixes#42
This change adds the logic to read a packet from the socket, accept
connections from clients, and close connections from clients that have
hung up. This commit does not yet have support for parsing and handling
the commands, and simply echoes the request back to the client.
This change makes X52 daemon listen on a Unix socket. This is in
preparation for changes that will read from the socket and allow clients
to communicate with and control the daemon.
This change adds a separate thread to initialize and read reports from
the supported X52 device. This will then process and raise input events
for a virtual device.
Prior to this change, x52d could only run in the foreground, regardless
of the value of the foreground flag. This change adds the standard
double-fork routine to daemonize the program.
This change also adds a PID file argument to x52d, which is used to
ensure that only one instance of the x52d daemon is running at any time.
This change adds the daemon configuration parser and command line
argument parser. This also adds the associated strings to the
translation files, and integrates the daemon into the existing autotools
build framework.
