`fs.stat` function for symlink pointing to directory in Windows



In my windows environment (x64), fs.stat function for symlink pointing to directory brings an error.


fs.stat


symlink



On the other hand, in appveyor (ia32), fs.stat function for symlink pointing to directory works well.


fs.stat


symlink



This is why? and which behavior is correct?



A part of my test code is


it('Test 001 : fs.stat for symlink', function ()
var target = path.resolve(workDir, 'sample1');
console.log('target :' + target);
fs.mkdirSync(target); // create directory
var link = path.resolve(workDir, 'link1');
console.log('link :' + link);
fs.symlinkSync(target, link); // create symlink to directory

expect(function()
var stat = fs.statSync(link); // checking symlink stat
console.log(stat);
).not.toThrow();

);



Please see https://github.com/knight9999/WindowsSymbolicLinkCheck for all codes.



The result of my local environment is


Failures:
1) win symlink tests Test 001 : fs.stat for symlink

Note:
I know that the symlinkd or junction is appropriate for directory in windows.
However fs.copy for a junction pointing to directory creates new symlink (neither symlinkd nor junction) automatically.


symlinkd


junction


fs.copy


junction


symlink


symlinkd


junction

However, I have added products for each plan and when I hit SELECT PLAN button I redirect to some custom form where I ask users range of info we are going to use to fulfil the plan (same as sneakertub.com).
