torrent.files[i].done is always false, even if file is fully downloaded

[romaincointepas]

• WebTorrent version: 0.94.3
• Node.js version: 6.1.0
• Electron version: 1.2.1

However, if I console.log(torrent.files[i]), I see done: true.

Any idea?

Sounds like it's probably a bug in your code. Are you checking the value of torrent.files[i] done before the file is actually done?

The file is done for sure.

I'm checking for file.done in the client.add callback (reopen the app with a torrent/file that has been downloaded in a previous session).

I'm also in an Electron renderer, if that matters.

Here is a quick test code:

client.add magnetURL, (torrent) ->
    file = torrent.files[0]
    console.log 'PRE-TEST'
    console.log file.done
    console.log file
    console.log file.done
    console.log 'POST-TEST'

And here is what I get in the Console:

Update
Checking for file.done next tick (process.nextTick()) shows true (the correct value). Is that expected behavior?

The file won't be done immediately when the onTorrent callback is called. You can listen for the 'done' event to find out when the file is done:

client.add(magnet, function (torrent) {
  var file = torrent.files[0]
  file.on('done', function () {
    file.done // true
  })
})

You're seeing that it's true when you expand the object in the inspector because the developer tools just save a reference to the object and don't resolve the values of it's properties until you expand the object.

If you hover over the 'i' icon in the interface you'll see:
