[slime-devel] inspecting network streams on sbcl

[Attila Lendvai]

hi!

when a network stream is inspected on sbcl then i get this error:

The value NIL is not of type PATHNAME.
   [Condition of type TYPE-ERROR]

Restarts:
  0: [ABORT] Return to sldb level 1.
  1: [CONTINUE] Return from BREAK.
  2: [TERMINATE-THREAD] Terminate this thread (#<THREAD "an httpd worker 21"

looking at swank.lisp it does check for (typep stream 'file-stream) but it
is T for socket streams which probably is the root of the problem.

also note the strange printed representation of the socket stream, but i
guess it's also an sbcl thing. maybe i should have written this to
sbcl-devel...

hth,
