[v2] Last written file is always empty

[dogancelik]

I have a Promise chain like this:

var q = require('q');
var fs = require("q-io/fs");

function save(filename, data) {
  return fs.write(filename, JSON.stringify(data, null, 2));
}

downloadAll.then(function () {
  var saves = [];
  // emotes is a global variable, has 10.000 objects
  saves.push(save('hello.json', { data: "hello" }));
  Object.keys(emotes).forEach(function (key) {
    saves.push(save(`${emotes[key].name}.json`, emotes[key]));
  });
  saves.push(save('bye.json', { data: "bye" }));
  return q.all(saves);
})
.then(function () {
  console.log('All files are saved');
});

bye.json is always empty, there is no data written.
If you switch places of hello.json and bye.json, this time hello.json becomes empty.

q version: ^1.4.1
q-io version: kriskowal/q-io#v2

Here's a temporary solution using module graceful-fs:

var fs = require('graceful-fs')
var q = require('q');
var writeFile = q.nfbind(fs.writeFile);

function save(filename, data) {
  return writeFile(filename, JSON.stringify(data, null, 2));
}
