Copying of symlinks fails

[joelgallant]

Fails here when a dependency contains a soft symlink that needs to be copied (failed to copy /home/joel/.cargo/git/checkouts/foo/sha1/foo/bar to /home/joel/dev/baz/vendor/foo/bar).

Where foo/bar is a symlink to another directory in the crate. I can replicate the same kinda thing with cp foo/bar dest, needs to be cp --no-dereference foo/bar dest. I don't know how to do the same thing with fs::copy, I haven't run in to that with std before. Would it need to check is_symlink and std::os::unix::fs::symlink manually?

Ah yeah this is a case where is_symlink and such will need to be manually used, but seems reasonable to me!

[joelgallant]

Seems similar if not the same kind of error as rust-lang/cargo#3896 - since fs::copy tries to follow the symlink

This crate is now included natively in Cargo as of rust-lang/cargo#6869 and today's nightly Rust. I'm closing all issues in this repository before I archive the repository, but if you're still interested in seeing this issue fixed then please feel free to file an issue with Cargo itself!
