annotate src/fns.c @ 5285:99de5fd48e87
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.
