Follow-up Comment #15, bug #59711 (project octave):
For an overview of inodes, see https://en.wikipedia.org/wiki/Inode.
Quoting from the article, "The POSIX standard mandates file-system behavior
that is strongly influenced by traditional UNIX file systems. An inode is
denoted by the phrase "file serial number", defined as a per-file system
unique identifier for a file.[9] That file serial number, together with the
device ID of the device containing the file, uniquely identify the file within
the whole system.[10]"
So, yes, it appears that a combination of device and inode is unique. From a
code perspective, it makes intuitive sense to use the canonical file name as
the key in a map. But if we have to abandon that because it is slow the only
people slightly inconvenienced will be Octave core programmers. Octave users
will never see this.
