With stdlib changes
File
now usesOwnedFd
internally that does IO safety checks in debug mode and that consequently causes the test here to panic as FDs of open files are closed behind stdlib's back. So this patch uses the low levellibc::open
to directly return aRawFd
, skipping thestd::fs::File::open
calls andas_raw_fd
conversion.Fixes: #1
