The problem is exactly as the title states. I've pasted a debug log. Here is some info

This looks like a permission problem with your /tmp directory. If you have the same setup on a different computer maybe compare notes on what permissions that directory has and whether your user can create new directories inside that.

Rimann91 commented 3 years ago

@alerque I just checked, i have read write and execute permissions on the tmp folder on both machines. I also tested and created a directory and a file to make sure. Also, I was mistaken, this doesn not work on either of my machines, I just tested the other one again and I must have only tried on the WLS side of that one before. The problem only occurs when trying to use tagbar on the mounted C drive

Is your gotags (or ctags if that's what is getting executed) installed via Snap, Flatpack, or some other containerized package system? This sounds like a security ACL of some kind kicking in prohibiting the process access to the file system even when your user could otherwise do so.

Rimann91 commented 3 years ago

No downloaded a release directly from here https://github.com/universal-ctags/ctags-win32/releases Snap currently isn't supported by WLS

alerque commented 3 years ago

I'm sorry I'm not much more use here, I really don't know what the issues is and without a Windows machine or any experience with the latest generation of WLS I really don't know where to go from here. We need input from someone with the right experience.

@Rimann91 as a workaround, does it work if you change your $TMP or $TMPDIR environment variable to something else? From other similar file system errors with the /tmp path from other vim scripts / plugins, I've seen people recommend adding something like the following in the .vimrc file to change the tempname() result.

For Linux:

let $TMPDIR=$HOME . '/tmp'

For Windows (at least I think you need to use a \ instead of /, though might need to escape it if this doesn't work directly... don't have windows vim setup to test it):

let $TMP=$HOME . '\tmp'

If this does work, then we can document this as a solution to change your tmp directory for vim. Note this does change the behavior of vim when using tempname(). See :h tempfile or :h tempname for more info.

I was having the same problem on my Ubuntu 18.04 box. Golang files would show in tagbar, but not Makefile targets. I have complex Makefiles.

Adding let $TMPDIR=$HOME . '/tmp' fixed it. Thank you @raven42 .

I would see an error referring to /tmp/vLI6Gek/14. I had no such file. I did have a /tmp/vLI6Gek/1
