Add array-dimension-limit and use it in #'make-vector, #'make-string. Add array-total-size-limit, array-rank-limit while we're at it, for the sake of any Common Lisp-oriented code that uses these limits. Rename check_int_range to check_integer_range, have it take Lisp_Objects (and thus bignums) instead. Remove bignum_butlast(), just set int_n to an appropriately large integer if N is a bignum. Accept bignums in check_sequence_range(), change the functions that use check_sequence_range() appropriately. Move the definition of NATNUMP() to number.h; document why it's a reasonable name, contradicting an old comment. tests/ChangeLog addition: 2010-11-20 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: * automated/lisp-tests.el (featurep): * automated/lisp-tests.el (wrong-type-argument): * automated/mule-tests.el (featurep): Check for args-out-of-range errors instead of wrong-type-argument errors in various places when code is handed a large bignum instead of a fixnum. Also check for the wrong-type-argument errors when giving the same code a non-integer value.

14 other changes should be preceded by a comment /* XEmacs change */.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
21 #define BROKEN_SIGIO. Jamie says:

25 3. All instances of HAVE_GETWD, HAVE_DUP2, HAVE_UNISTD_H, NEED_UNISTD_H,
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
26 HAVE_GETTIMEOFDAY and NEED_REALPATH removed. We detect these
376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14

30 support X10 or earlier so the HAVE_X11 define was purged.

32 5. Most of the signal crap (e.g. redefining sigsetmask, defining
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
33 POSIX_SIGNALS) has been removed. There are four possible
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
34 signal paradigms that all systems fall into, and we auto-detect
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

35 them in configure and handle them in syssignal.h.

37 6. Removed references to INTERRUPT_INPUT. XEmacs does not use
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

38 this bizarre way of reading input.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
41 in INTERRUPT_INPUT and in the select() emulator, neither of
376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14

45 and in FSF Emacs.

376386a54a3c Import from CVS: tag r19-14
cvs
parents:

48 They are unnecessary with the cleaned up syswait.h in XEmacs.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
49 (We autodetect sys/wait.h). Instead, #define or #undef
376386a54a3c Import from CVS: tag r19-14
cvs

50 HAVE_UNION_WAIT.

52 10. Removed BSTRING. Not used anywhere. (If the header file
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
53 says there are bugs in bcopy() or the like, however, a
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

54 #define BROKEN_BCOPY is added for reference.)

376386a54a3c Import from CVS: tag r19-14

57 XEmacs makes consistent use of the ANSI-equivalent

376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
69 HAVE_TCATTR (when HAVE_TERMIOS was also defined).
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
70 configure detects these and systty.h automatically defines
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

71 HAVE_TCATTR when HAVE_TERMIOS is defined.
