Issue #13568 has been updated by Hanmac (Hans Mackowiak).


like i said, open with write mode is the problem.
because it didn't fail with the nonexistent path

an way for it to make it work for printf or logger would be to make it's #inspect working (with not using path in that case)

about the filesystem, can #stat be used for something like that?

Feature #13568: File#path for O_TMPFILE fds are unmeaning

----------------------------------------
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.
