Window dimensions aren't updated properly

[MatthewRock]

This code snippet is the smallest isolated case of bug I can find:

(defun test ()
  (charms:with-curses ()
    (multiple-value-bind (width height) (charms:window-dimensions cl-charms:*standard-window*)
      (print (list width height)))))

Bug description: The bug prevents window dimensions from being updated properly - it prints dimensions from previous window.

Steps to reproduce:

1. Open a window with sbcl compiler.
2. run #'test
3. After test finishes its execution, resize the window.
4. Run test again.
5. After test finishes its execution, run test again.

Result: (proper-x proper-y) (old-x old-y) (proper-x proper-y)

Expected: (proper-x proper-y) x 3

I'm running SBCL 1.3.4 with cl-charms-20160318-git, downloaded with quicklisp.

I've poked around the code, but I have no idea what's wrong. I've tried changing the #'standard-window closure by creating a function that resets %cached-window, then change #'finalize so that each time my program ends, the %cached-window gets rebound, but this didn't solve the problem. Same with using (gc) in between the calls to #'test. Moreover, the program looks similarly to what I've got in C. Any ideas?

Probably you should refresh window before retrieving width/height like:

(defun test ()
  (charms:with-curses ()
    (charms:refresh-window cl-charms:*standard-window*)
    (multiple-value-bind (width height) (charms:window-dimensions cl-charms:*standard-window*)
      (sleep 3)
      (print (list width height)))))
