What steps will reproduce the bug?
//call mkdir with to create a non existing directory and then when complete call it again with the same directory.
fs.mkdir('c:\\temp\\testdirnonexist',{ recursive: true }, function(){
console.log('first time', arguments.length); //result 2
fs.mkdir('c:\\temp\\testdirnonexist',{ recursive: true }, function(){
console.log('second time', arguments.length); //result 1
});
});How often does it reproduce? Is there a required condition?
Always
What is the expected behavior?
Always return the same number of arguments.
This is important for example when you pass an async waterfall callback to mkdir.
What do you see instead?
if the directory exists only 1 arguments will be returned (error argument which is null)
if directory is created then it returns null, and the path.
