Issue #13568 has been updated by matz (Yukihiro Matsumoto).


I vote for raising exceptions (ENOENT?).

Feature #13568: File#path for O_TMPFILE fds has no meaning

----------------------------------------
By using File::TMPFILE (O_TMPFILE) allows us to create a file without directory entries.

While open(2) with O_TMPFILE don't create a file without directory entries, it still requires a directory name to determine a file system to create a file.

Current Ruby implementation holds such directory names in fptr->pathv and retrievable via File#path.
But such paths are useless and may raise errors. For example, some code [1] checks File#path availability then when available, it attempts to use the path to open a file in different fd, finally raises Errno::EISDIR.

This patch changes File#path (fptr->pathv) not to return String if a fd is opened with O_TMPFILE.
