Cargo build tries to read files that it has no permissions for (Permission denied (os error 13))

Problem

I want to compile my code on a cluster. Clusters are messy sometimes, and as such in the /home directory of our system someone or something made a mess, creating all sorts of directories, one of which is called Cargo.toml.

When building Cargo.toml the compiler fails:

error: failed to read `/Users/Cargo.toml`

Caused by:
  Permission denied (os error 13)

Steps

These work on any system :)

1. cd ~/..
2. sudo mkdir Cargo.toml or sudo touch Cargo.toml
3. sudo chmod 300 Cargo.toml
4. try to compile any project...

Possible Solution(s)

Probably plenty

• Check permissions before writing files
• Do not read stuff outside of the user directory
• Blacklist or whiltelist search paths

FYI in the future, you might run into problems with #10736

One workaround is to put [workspace] in your project which will tell cargo it shouldn't walk up the directory hierarchy to find if a Cargo.toml with a [workspace] exists.

Thank you so much. This works. I am closing this issue.
