Same change as #55417 , but we should make it for Systemd.
// systemd sends SIGTERM to stop the service.
AppDomain . CurrentDomain . ProcessExit += OnProcessExit ;
return Task . CompletedTask ;
}
private void OnApplicationStarted ( )
{
Logger . LogInformation ( "Application started. Hosting environment: {EnvironmentName}; Content root path: {ContentRoot}" ,
Environment . EnvironmentName , Environment . ContentRootPath ) ;
SystemdNotifier . Notify ( ServiceState . Ready ) ;
}
private void OnApplicationStopping ( )
{
Logger . LogInformation ( "Application is shutting down..." ) ;
SystemdNotifier . Notify ( ServiceState . Stopping ) ;
}
private void OnProcessExit ( object sender , EventArgs e )
{
ApplicationLifetime . StopApplication ( ) ;
_shutdownBlock . WaitOne ( ) ;
// On Linux if the shutdown is triggered by SIGTERM then that's signaled with the 143 exit code.
// Suppress that since we shut down gracefully. https://github.com/dotnet/aspnetcore/issues/6526
System . Environment . ExitCode = 0 ;
}
We should also figure out how to add real tests, as I don't believe there are any tests for this library, yet. The only test we have:
public void DefaultsToOffOutsideOfService ( )
{
var host = new HostBuilder ( )
. UseSystemd ( )
. Build ( ) ;
using ( host )
{
var lifetime = host . Services . GetRequiredService < IHostLifetime > ( ) ;
Assert . IsType < ConsoleLifetime > ( lifetime ) ;
}
}
tests that Systemd is "off" when not in a systemd service.
