What is the full CLI command that you're using?

[sunilrx]

$ webtorrent-hybrid node_modules/webtorrent-hybrid/sintel.torrent --keep-seeding

[feross]

I can confirm this issue on Ubuntu 14.04.5 LTS x64.

@mappum This appears to be another electron-eval bug. (I confirmed I'm using the latest version of it.) It happens at the end of torrenting when peer connections are closed.

Here's a command you can use to reproduce on Ubuntu:

webtorrent-hybrid https://webtorrent.io/torrents/sintel.torrent --keep-seeding

Here is the full stack trace that I get:

Im getting the same error but posted in the wrong issue.. https://github.com/feross/webtorrent-hybrid/issues/29#issuecomment-251567346

[DiegoRBaquero]

@FLYBYME This actually has the same error output as #29 and we didn't have full stack trace in the previous issue. Meaning this could be the same error and a commit brought the issue again.

[FLYBYME]

@DiegoRBaquero What version do you that works?

[FLYBYME]

I just installed v1.0.2 and its not kicking out the error.

[feross]

@FLYBYME Do you mean that the issue is fixed? Or, are you saying that you can't get a detailed error log anymore?

[FLYBYME]

@feross With version 1.0.2 running this command webtorrent-hybrid https://webtorrent.io/torrents/sintel.torrent --keep-seeding I do not get the error anymore.

BUT when I run this code I still get the error..

var WebTorrent = require('webtorrent-hybrid');
var keystone = require('keystone');
var jobs = keystone.jobs;
var client = new WebTorrent({
    port : 23543,
    dht : false
});

client.on('error', function(err) {
    // fatal server error!
    console.log(err.message);
});
function create(job, done) {
    console.log(job)
    var folder = job.data.folder || './torrents/files';
    var torrent = client.add(job.data.torrent, {
        path : folder
    }, function(torrent) {

    });
    torrent.on('infoHash', function() {
        console.log('infoHash');
    });

    torrent.on('metadata', function() {
        console.log('metadata');
    });

    torrent.on('ready', function() {
        console.log('ready');
    });
    torrent.on('warning', function(err) {
        console.log('warning', err);
    });
    torrent.on('error', function(err) {
        console.log('error', err);
        done(err);
    });
    torrent.on('done', function() {
        console.log('done');
        done();
    });
    torrent.on('download', function(bytes) {
        //console.log((torrent.progress * 100).toFixed(2) + '%');
        if (job.progress)
            job.progress((torrent.progress * 100).toFixed(2), 100);
    });
}

jobs.process('torrent download', 10, create);

keystone.list('Torrent').model.find({
    state : 'published'
}).exec(function(err, results) {
    results.forEach(function(torrent) {
        create({
            data : {
                torrent : torrent.torrent.path + '/' + torrent.torrent.filename,
                folder : torrent.folder
            }
        }, function() {
            //
        });
    });
});

Having similar problems using both Windows and Linux. On Windows it crashes and gives off an error as soon as you start seeding a file. On Linux it crashes and gives off an error if a peer disconnects from your torrent.

Got this error message while I tried to exit using Ctrl+C on Ubuntu 18.04. Anything to do with the script not being able to exit gracefully?

Command: webtorrent-hybrid <torrent-file-url> --keep-seeding

^C
webtorrent is exiting...
