File#path: Raise IOError when a file is O_TMPFILE
File#path for a file opened with O_TMPFILE has no meaning.
A filepath returned by this method isn't guarranteed about its accuracy,
but files opened with O_TMPFILE are known its recorded path has no
meaning. So let them not to return any pathname.
After a discussion in ruby-core, just returning Qnil makes guessing the
root cause difficult. Instead, this patch makes the method to raise an
error.
Other consideration is calling fnctl(2) on rb_file_path, but it adds a
overhead, and it's difficult to determine O_TMPFILE status after fd has
been closed.
[Feature #13568]
* io.c(rb_file_open_generic): Set Qnil to fptr->pathv when opening a
file using O_TMPFILE
* file.c(rb_file_path): Raise IOError when fptr->pathv is Qnil
* file.c(rb_file_path): [DOC] Update for the new behavior
