* alloc.c, frame.c, frame.h, indent.c, keyboard.c, keyboard.h,
lisp.h, term.c, termhooks.h, window.c, window.h, xdisp.c, xfns.c,
xterm.c, xterm.h: Terminology changed.

(mark_interval_tree): Pass new arg to traverse_intervals.
|
|
aligned, not pureptr itself.

if it's available, or sizeof (struct Lisp_Float) if it's not.
|
|
boundary before allocating the float.
* alloc.c: Add description lines to the top of each page.
* alloc.c (mark_interval_tree): Remove spurious & in front of
function name.
* alloc.c (UNMARK_BALANCE_INTERVALS): Fix to accomodate compilers
other than GCC, which do not allow casts on the LHS of an
assignment.
* alloc.c (mark_object, mark_buffer): Remove some unused
variables.

GC'd; this allows windows and scrollbars can refer to each other
without worrying about dangling pointers.
* xterm.h (struct x_display): vertical_scrollbars and
judge_timestamp members deleted.
(struct scrollbar): Redesigned to be a template for a Lisp_Vector.
(SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
New macros, to help deal with the lispy structures, and deal with
the graphics.
* frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
(struct frame): New fields `scrollbars' and
`condemned_scrollbars', for use by the scrollbar implementation.
[MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
* window.h (struct window): Doc fix for vertical_scrollbar field.
* frame.c (make_frame): Initialize the `scrollbars' and
`condemned_scrollbars' fields of the new frame.
* alloc.c (mark_object): Mark the `scrollbars' and
`condemned_scrollbars' slots of frames.
* xterm.c (x_window_to_scrollbar): Scrollbars are chained on
frames' scrollbar field, not their x.display->vertical_scrollbars
field.
(x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
x_scrollbar_remove, XTset_vertical_scrollbar,
XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
x_scrollbar_expose, x_scrollbar_handle_click,
x_scrollbar_handle_motion): Substantially rewritten to correct
typos and brainos, and to accomodate the lispy structures.

right thing when MULTI_FRAME isn't defined.
|
|
|
|
to traverse_intervals().
|
|
Don't bother trying to display the size in the minibuffer.
|
|
(syms_of_alloc): Defsubr it.

(init_intervals, make_interval,
mark_interval, mark_interval_tree): New functions conditionally
defined.
(make_uninit_string): Call INITIALIZE_INTERVAL.
(INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
New macros, conditionally defined.
(mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
(gc_sweep): If text properties are in use, place all unmarked
intervals on the free list. Call UNMARK_BALANCE_INTERVALS on
`buffer->intervals' when unmarking `buffer'.
(compact_strings): Include INTERVAL_PTR_SIZE in calculation for
target of bcopy when relocating strings.
(init_alloc_once): Call INIT_INTERVALS.
(make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
`size'.

Avoid recursion on constants-vector of a compiled function.
|
|
Check for clobberage of ptr, when marking a vector.
|
|
value, function, and property list rather than before; this way,
symbols' names are readable, giving us a chance to detect some
kinds of heap corruption.
|
|
signal handler. The original bug is probably gone, the test
wasn't written portably, and it should probably go somewhere else
anyway - say, funcall or eval.
