OddJob was born out of the need to run both a long running process and a HttpServer within a single command line application, along with handling graceful shutdown of the process when signalled by the OS.
Unhandled exceptions by jobs (with the exception of scheduled jobs) will signal a cancellation to all jobs to gracefully end, eventually exiting the process.
class Program
{
static int Main(string[] args)
{
using (var loggerFactory = new LoggerFactory())
{
loggerFactory.AddConsole();
var builder = new OddJob.JobHostBuilder()
.Add<BackgroundJob>()
.UseLoggerFactory(loggerFactory);
return builder.BuildAndRun();
}
}
}
public class BackgroundJob : OddJob.Jobs.Forever
{
protected override async Task DoAsync()
{
Console.WriteLine("tick");
await Task.Delay(1000);
}
}Jobs can be run on a schedule. Schedules can be implement using the ISchedule interface
class Program
{
static int Main(string[] args)
{
using (var loggerFactory = new LoggerFactory())
{
loggerFactory.AddConsole();
var builder = new OddJob.JobHostBuilder()
.Add(() => new MyJob(loggerFactory), Schedule.Every().Hour())
.UseLoggerFactory(loggerFactory);
return builder.BuildAndRun();
}
}
}
public class MyJob : IJob
{
private readonly ILoggerFactory loggerFactory;
public MyJob(ILoggerFactory loggerFactory)
{
this.loggerFactory = loggerFactory;
}
public async Task RunAsync(CancellationToken cancellationToken)
{
var logger = this.loggerFactory.CreateLogger<MyJob>();
logger.LogInformation("tick");
await Task.CompletedTask;
}
}
