Proposed patch
Hi Rich,
> 1. make_tempname with fd_return==NULL is *always* a bug,
Well, I would argue that it is only a bug if the temporary file is going to
be manipulated by other system functions. But it is also true that if a
caller does not want the file descriptor they can always close/discard it.
So I am attaching an updated patch which adds ATTRIBUTE_NONNULL to both of
the parameters to make_tempname(). That way the compiler will ensure that
any caller always receives the file descriptor.
> 2. smart_rename needs(*) *two* fds, not just one
Actually it does this. It is just that only one fd is passed in (the open
temporary file). The function itself opens the destination file before it
attempts to perform any other operations on it.
Cheers
Nick
