Programmatically stop croner

[davoam]

Thanks for the library!

Is there any way to programmatically stop croner? My Jest tests hangs until I manually kill tests process

[Hexagon]

Yeah, you can stop it from both "inside" and "outside".

const job = Cron('xxx', (_job) => { /* option 1 */ _job.stop();});

// Option 2
job.stop();

Works? :)

See internal test suite for examples of promise handling https://github.com/Hexagon/croner/blob/master/test/src/suite.cjs

Thanks for the quick response! Yeah, I stopped all the jobs this way, but the process itself keeps running. If there are no running jobs, croner stops the process?

It seems like there is a pending setTimeout or Promise which prevents the process from being killed

Hmm, croner does not fork processes or anything, it's basically a setTimeout, where .stop() run clearTimeout. Are you sure your scheduled function does not leave anything running?

If croner causes this, it would be awesome if you could pinpoint the problem and paste some code here, so i can have a look at it :)

I'll try, when I have time :) Thanks!

Great, tried to reproduce it using different techniques, but this is the only one that finish the scheduled function, but keep node running "unexpectedly".

const Cron = require("croner");

async function runsToInfinity() { setTimeout(runsToInfinity, 1000); }

const job = Cron('* * * * * *', async (self) => {

    // No await
    runsToInfinity();

    // Option 1, will not stop execution
    console.log('Yay, done!');
    self.stop();
} );

// Option 2 (wait 2 seconds to make sure execution is started)
// ... will not stop execution either
setTimeout( () => { 
    console.log('Yay, done again!'); 
    job.stop(); 
}, 2000);

Closing this, since there are no steps to reproduce.

Please reopen if you find and document a way to reproduce this
