[ehmicky]

Don't we want to use fs.stat() instead of fs.lstat() here?
I'm not sure it can actually ever be a symlink there, but if it was, would we want the size of the symlinked path, or the symlinked content?

[eduardoboucas]

It won't ever be a symlink in this case because we're opening the ZIP file we're creating ourselves, but I agree that there's no reason to use lstat. I replaced it with stat in 6a75c74.
