Just updated the ticket.
As I commented, the heuristic for checking if a file has been modified lies
in line 282 of collectstatic.py:
*if not prefixed_path in self.copied_files:*
*
return self.log("Skipping '%s' (already copied earlier)" % path)
*
https://github.com/django/django/blob/master/django/contrib/staticfiles/management/commands/collectstatic.py#L282
This seems off, since a path may stay the same but a file's contents may
change.
Also, the existing functionality doesn't work when multiple people are
running collectstatic (or the same person is running it on multiple
computers).
