…nks, r=<try> bootstrap: fix clean's remove_dir_all implementation It turns out bootstrap's `clean.rs`'s hand-rolled `rm_rf` (which probably comes before `std::fs::remove_dir_all` was stable) is very broken on native Windows around both read-only files/directories and especially symbolic links. So instead of rolling our own, just use `std::fs::remove_dir_all`. Because I wasn't super sure about `std::fs::remove_dir_all`'s behavior and to catch `std::fs::remove_dir_all`'s behavioral changes here on forward, I added a collection of tests that checks if our expectation of the behavior of `std::fs::remove_dir_all` and its underlying Unix syscalls and Win32 APIs matches with its actual behavior. This is a blocker for compiletest's own `rm_rf` implementation rust-lang#129155 which happens to be also buggy, which in turn is a blocker for the rmake.rs test port rust-lang#128562 that heavily exercises symlinks (I was reviewing rust-lang#128562 and testing it on native Windows which is how I found out). I also left a FIXME for `detect_src_and_out` due to a failing assertion on native Windows: ``` ---- core::config::tests::detect_src_and_out stdout ---- thread 'core::config::tests::detect_src_and_out' panicked at src\core\config\tests.rs:72:13: assertion `left == right` failed left: "E:\\tmp" right: "C:\\tmp" ``` Fixes rust-lang#112544 (because now we handle Windows symlinks properly). try-job: x86_64-msvc try-job: i686-mingw try-job: test-various try-job: armhf-gnu try-job: aarch64-apple try-job: aarch64-gnu

If I use
./xin WSL2 it will create a host symlink in the build directory. If I then switch to the Windows host using the same build directory I get this error:The simplest solution here would be to detect
ERROR_DIRECTORY(aka os error 267) and fallback tofs::remove_file.The text was updated successfully, but these errors were encountered:
