;;;; DIRECTORY
(/show0 "filesys.lisp 800")
+;;; NOTE: There is a fair amount of hair below that is probably not
+;;; strictly necessary.
+;;;
+;;; The issue is the following: what does (DIRECTORY "SYS:*;") mean?
+;;; Until 2004-01, SBCL's behaviour was unquestionably wrong, as it
+;;; did not translate the logical pathname at all, but instead treated
+;;; it as a physical one. Other Lisps seem to to treat this call as
+;;; equivalent to (DIRECTORY (TRANSLATE-LOGICAL-PATHNAME "SYS:*;")),
+;;; which is fine as far as it goes, but not very interesting, and
+;;; arguably counterintuitive. (PATHNAME-MATCH-P "SYS:SRC;" "SYS:*;")
+;;; is true, so why should "SYS:SRC;" not show up in the call to
+;;; DIRECTORY? (assuming the physical pathname corresponding to it
+;;; exists, of course).
+;;;
+;;; So, the interpretation that I am pushing is for all pathnames
+;;; matching the input pathname to be queried. This means that we
+;;; need to compute the intersection of the input pathname and the
+;;; logical host FROM translations, and then translate the resulting
+;;; pathname using the host to the TO translation; this treatment is
+;;; recursively invoked until we get a physical pathname, whereupon
+;;; our physical DIRECTORY implementation takes over.
+
+;;; FIXME: this is an incomplete implementation. It only works when
+;;; both are logical pathnames (which is OK, because that's the only
+;;; case when we call it), but there are other pitfalls as well: see
+;;; the DIRECTORY-HELPER below for some, but others include a lack of
+;;; pattern handling.
