Hi,
I'm having an issue on windows : unlink=1 is not working (temp file are still there) and it's working fine on unix
Looking at the code in close_and_free_files function :
[...]
if (td->o.unlink && f->filetype == FIO_TYPE_FILE) {
dprint(FD_FILE, "free unlink %s\n", f->file_name);
unlink(f->file_name);
}
[...]
Unlink() fails because the file is still open : On Solaris, truss shows the following :
[...]
write(3, "\0\0\0\0\0 ;80\0\0\0\0\0".., 32768) = 32768
unlink("/data/fio/random_rw.0.0") = 0
close(3) = 0
[...]
So unlink is called first.
I would put this unlinking phase AFTER the remove_file_hash call.
Sure, we can move the unlink down a bit, should not matter really. Linux
doesn't care when you call unlink, last close will just really unlink
it. But if other operating systems do care, then I'll just move it.
