win, fs: detect if symlink target is a directory #23724

bzoz · 2018-10-18T00:46:01Z

On Windows creating a symlink to a directory will not work unless extra 'dir' parameter is passed. This adds a check if link target is a directory, and if so automatically use 'dir' when creating the symlink.

@refack: If a user creates a symlink to a folder, removes the folder and creates a file with the same name as the folder, currently the symlink will work, and the user will be able to access the file. With this change, the symlink will be broken. It's an obscure corner case, but still, this is why I think its semver-major.

The git node thingy complains that I need 2 TSC approvals for semver-major change.. so, ping?

rvagg · 2018-11-22T10:52:57Z

OK, so a few questions:

What happens if you supply type='file' for a directory and vice versa on Windows? (background I don't understand)
With this change, what's the point of the type argument now? Is that just useful for junction? Or does the answer to the question above suggest other novel uses?
Should the docs be updated to reflect this new behaviour? They currently say the default is 'file' which it clearly isn't after this change and may not even be before this change (although again, I'm missing background on how Windows does symlinks).

bzoz · 2018-11-22T11:23:43Z

type='file' for a target that is a directory:
- fs.readdir or cd/dir in the shell will not work
- if there is a subfolder in the driectory both fs.readdir('link/subdir') and cd link\subdir/dir link/subdir in the shell will work
type='dir' to a target that is a file: nothing works
junction and to override the detection. If the target does not exists, 'file' will be used by default, if one knows that the link will point to a directory, the type argument can be used
Yeah, it should. I'm on it.

rvagg · 2018-11-22T11:30:54Z

OK, that blows my mind a little bit. But I think the take-away is that the flexibility might be handy for obscure cases but doing best-guess for the user is going to be optimal. Sounds good then.

Any reason not to use this instead?:

Suggested change

Then you don't need to disable the ESLint rule. The usual reason to avoid that catch syntax would be to simplify backporting to 8.x and 6.x but this is a semver-major so that's not an issue here.

win, fs: detect if symlink target is a directory

7abe623

On Windows creating a symlink to a directory will not work unless extra 'dir' parameter is passed. This adds a check if link target is a directory, and if so automatically use 'dir' when creating symlink. Ref: nodejs#23691

bzoz force-pushed the bartek-win-dir-symlink branch from 4ae122e to 7abe623 Compare November 29, 2018 11:29
