failure to delete temporary files on rustup update

[steveklabnik]

I just updated to the latest nightly, and was greeted with this:

it did successfully update though.

apparently they require administrator access?

even typing rm in an adminstrative shell won't delete them...

I've just run into this, but it's really weird. When I try to delete the files in Explorer, I get:

If I try to delete the file mentioned, I get:

So, I fire up Process Explorer as admin, and...

It's not there. I also tried searching for the process holding the files open with handle, but it came up empty.

So, as a last resort, I shut down VS Code to terminate the RLS process which, to be clear, was running before I updated through rustup. Doing this allowed me to delete all of those temp files.

I have no idea how any of this makes any damn sense. Sadly, I can't do any further testing on this, since my tmp folder is now empty.

I had the exact same experience yesterday, actually. Temp files kept mysteriously open, very difficult to track down. I was just about to restart, when I thought to try closing VS Code, which allowed me to delete the files.

I'd started rustup update from a fresh Powershell window, to be clear, not from the console within VS Code.

Recently started having the same problem. My guess is that is could be related to RLS, since this issue only seems to occur whenever I have Sublime Text 3 with RLS open.

I can confirm it was solved when i closed Visual Studio Code with a Rust Project active and it is probably RLS that keep the files in tmp open.

Particularly in Windows, running rustup update when anything could be using a toolchain is risky. That means any rls or rust-analyzer instances, or anything running cargo rustc rustdoc rustfmt etc.

I'm closing this in favour of #2441, which although not an exact match is aiming at the systematic problem of how we tackle updates on windows.
