Tighten up Common Lisp compatibility, #'butlast, #'nbutlast, #'tailp, #'ldiff lisp/ChangeLog addition: 2010-10-14 Aidan Kehoe <kehoea@parhasard.net> * byte-optimize.el (side-effect-free-fns): * cl-macs.el (remf, getf): * cl-extra.el (tailp, cl-set-getf, cl-do-remf): * cl.el (ldiff, endp): Tighten up Common Lisp compatibility for #'ldiff, #'endp, #'tailp; add circularity checking for the first two. #'cl-set-getf and #'cl-do-remf were Lisp implementations of #'plist-put and #'plist-remprop; change the names to aliases, changes the macros that use them to using #'plist-put and #'plist-remprop directly. src/ChangeLog addition: 2010-10-14 Aidan Kehoe <kehoea@parhasard.net> * fns.c (Fnbutlast, Fbutlast): Tighten up Common Lisp compatibility for these two functions; they need to operate on dotted lists without erroring. tests/ChangeLog addition: 2010-10-14 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el (x): Test #'nbutlast, #'butlast with dotted lists. Check that #'ldiff and #'tailp don't hang on circular lists; check that #'tailp returns t with circular lists when that is appropriate. Test them both with dotted lists.
