Cargo is broken on Windows Docker since #7137

[zeevm]

7137 introduced using fs::canonicalize in fingerprint.rs (4f6553a)

canonicalize on Windows is implemented using GetFinalPathNameByHandleW which fails on directories that are bind mounted, result being Cargo fails building inside Windows containers when building a source tree that is bind mounted from the host.

To reproduce:

1. Create a new crate source tree (cargo new) on Windows
2. Create a Windows container
3. Start the container and bind mount the source tree inside the container
4. Build the source tree inside the container

Result: build fails

Thanks for the report! Can you gist the error message coming out of this?

Also cc @ehuss, you might be interested in this!

This issue becomes critical to us. Can you please comment if any fix is planned soon?

I'm going to close as I cannot reproduce the original issue. Perhaps an update in Docker or Windows has fixed the filesystem issue. Additionally, #11866 has been merged which does a fallback for canonicalization.

If anyone can reproduce this on the latest nightly, please include a complete reproduction, including a Dockerfile, the version of Docker and Windows, WSL information, etc.
