copyFileSync expected behavior?

[favio41]

• Version:8.6.0
• Platform: 16.04.1-Ubuntu
• Subsystem:fs

I'm getting what I think is an unexpected behavior when I use this function

const fs = require('fs');
fs.copyFileSync('numeric.log', 'alpha.log');

using this files:
numeric.log:

1
2
3

alpha.log

a
b
c
d
e

I'm expecting a full rewrite of my destination file, but instead, I get:
alpha.log

1
2
3
d
e

Is this the intended behavior? If yes I recommend this should be disclosed on the docs.

Thank you!

I think this should be fixed once #15745 lands. See: libuv/libuv#1552

Yes, it sounds like that. I will wait for the new release.

Thank you for your quick response!
