various fixes to memory-usage stats
-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-03-25 Ben Wing <ben@xemacs.org>
* diagnose.el (show-memory-usage):
* diagnose.el (show-object-memory-usage-stats):
Further changes to correspond with changes in the C code;
add an additional column in show-object-memory-usage-stats showing
the ancillary Lisp overhead used with each type; shrink columns for
windows in show-memory-usage to get it to fit in 79 chars.
src/ChangeLog addition:
2010-03-25 Ben Wing <ben@xemacs.org>
* alloc.c:
* alloc.c (struct):
* alloc.c (finish_object_memory_usage_stats):
* alloc.c (object_memory_usage_stats):
* alloc.c (Fobject_memory_usage):
* alloc.c (lisp_object_memory_usage_full):
* alloc.c (compute_memusage_stats_length):
* lrecord.h:
* lrecord.h (struct lrecord_implementation):
Add fields to the `lrecord_implementation' structure to list an
offset into the array of extra statistics in a
`struct generic_usage_stats' and a length, listing the first slice
of ancillary Lisp-object memory. Compute automatically in
compute_memusage_stats_length(). Use to add an entry
`FOO-lisp-ancillary-storage' for object type FOO.
Don't crash when an int or char is given to object-memory-usage,
signal an error instead.
Add functions lisp_object_memory_usage_full() and
lisp_object_memory_usage() to compute the total memory usage of an
object (sum of object, non-Lisp attached, and Lisp ancillary
memory).
* array.c:
* array.c (gap_array_memory_usage):
* array.h:
Add function to return memory usage of a gap array.
* buffer.c (struct buffer_stats):
* buffer.c (compute_buffer_usage):
* buffer.c (vars_of_buffer):
* extents.c (compute_buffer_extent_usage):
* marker.c:
* marker.c (compute_buffer_marker_usage):
* extents.h:
* lisp.h:
Remove `struct usage_stats' arg from compute_buffer_marker_usage()
and compute_buffer_extent_usage() -- these are ancillary Lisp
objects and don't get accumulated into `struct usage_stats';
change the value of `memusage_stats_list' so that `markers' and
`extents' memory is in Lisp-ancillary, where it belongs.
In compute_buffer_marker_usage(), use lisp_object_memory_usage()
rather than lisp_object_storage_size().
* casetab.c:
* casetab.c (case_table_memory_usage):
* casetab.c (vars_of_casetab):
* emacs.c (main_1):
Add memory usage stats for case tables.
* lisp.h:
Add comment explaining the `struct generic_usage_stats' more,
as well as the new fields in lrecord_implementation.
* console-impl.h:
* console-impl.h (struct console_methods):
* scrollbar-gtk.c:
* scrollbar-gtk.c (gtk_compute_scrollbar_instance_usage):
* scrollbar-msw.c:
* scrollbar-msw.c (mswindows_compute_scrollbar_instance_usage):
* scrollbar-x.c:
* scrollbar-x.c (x_compute_scrollbar_instance_usage):
* scrollbar.c:
* scrollbar.c (struct scrollbar_instance_stats):
* scrollbar.c (compute_all_scrollbar_instance_usage):
* scrollbar.c (scrollbar_instance_memory_usage):
* scrollbar.c (scrollbar_objects_create):
* scrollbar.c (vars_of_scrollbar):
* scrollbar.h:
* symsinit.h:
* window.c:
* window.c (find_window_mirror_maybe):
* window.c (struct window_mirror_stats):
* window.c (compute_window_mirror_usage):
* window.c (window_mirror_memory_usage):
* window.c (compute_window_usage):
* window.c (window_objects_create):
* window.c (syms_of_window):
* window.c (vars_of_window):
Redo memory-usage associated with windows, window mirrors, and
scrollbar instances. Should fix crash in find_window_mirror,
among other things. Properly assign memo ry to object memory,
non-Lisp extra memory, and Lisp ancillary memory. For example,
redisplay structures are non-Lisp memory hanging off a window
mirror, not a window; make it an ancillary Lisp-object field.
Window mirrors and scrollbar instances have their own statistics,
among other things.
