I built a hash table with keys that were simple cons cells of the form

(<type> . <item>)

I had a few <type>s, and lots of atomic <item>s (in particular, strings) for each <type>. The performance was very bad.

Investigation showed that ccl::compute-hash-code was returning a hash code that depended only on the <type> but not on the <item>, meaning that hash table look up was degenerating into a linear search.

Example:

(setq h (make-hash-table :test #'equal))

Then

(ccl::compute-hash-code h '(type . "foo") nil)
(ccl::compute-hash-code h '(type . "bar") nil)
(ccl::compute-hash-code h '(type . "baz") nil)
(ccl::compute-hash-code h '(type . pi) nil)
(ccl::compute-hash-code h '(type . nil) nil)

all return exactly the same results.

In first Listener (from boot), when a form/expression in Listener history is evaluated (by moving cursor to form end and pressing enter), the following error is printed to altconsole. Subsequent evaluations of any listener don't cause this error.

Lisp error: "The value NIL is not of the expected type CHARACTER."

I am using Ubuntu hardy, Linux hayaji 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64 GNU/Linux.
