Be more careful about side-effects from Lisp code, #'reduce
src/ChangeLog addition:
2010-07-24 Aidan Kehoe <kehoea@parhasard.net>
* lisp.h (PARSE_KEYWORDS):
Always accept a nil :allow-other-keys keyword argument, as
described in the ALLOW-OTHER-KEYS-NIL Common Lisp issue writeup,
and as necessary for Paul Dietz' tests for #'reduce.
* fns.c (mapping_interaction_error): New.
(Freduce): Call mapping_interaction_error when KEY or FUNCTION
have modified a string SEQUENCE such that the byte length of the
string has changed, or such that the current cursor pointer
doesn't point to the beginning of a character.
Cf. the MAPPING-DESTRUCTIVE-INTERACTION Common Lisp issue
writeup.
When traversing a list, GCPRO the part of it we still have to
traverse, to avoid any crashes if FUNCTION or KEY amputate it
behind us and force a garbage collection.
tests/ChangeLog addition:
2010-07-24 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test a couple of things #'reduce was just made more careful
about.
