more cleanups to object-memory-usage stuff
-------------------- ChangeLog entries follow: --------------------
lisp/ChangeLog addition:
2010-03-19 Ben Wing <ben@xemacs.org>
* diagnose.el (show-object-memory-usage-stats):
Rewrite to take into account non-lisp-storage statistics
returned by garbage-collect-1 and friends.
src/ChangeLog addition:
2010-03-19 Ben Wing <ben@xemacs.org>
* alloc.c:
* alloc.c (struct):
* alloc.c (tick_lrecord_stats):
* alloc.c (gc_sweep_1):
* alloc.c (finish_object_memory_usage_stats):
* alloc.c (object_memory_usage_stats):
* alloc.c (compute_memusage_stats_length):
Call new memory-usage mechanism at sweep time to compute extra
memory utilization for all objects. Add up the values element-by-
element to get an aggregrate set of statistics, where each is the
sum of the values of a single statistic across different objects
of the same type. At end of sweep time, call
finish_object_memory_usage_stats() to add up all the aggreggrate
stats that are related to non-Lisp memory storage to compute
a single value, and add it to the list of values returned by
`garbage-collect' and `object-memory-usage-stats'.
* buffer.c (compute_buffer_text_usage):
Don't crash on buffers without text (killed buffers?) and don't
double-count indirect buffers.
* elhash.c:
* elhash.c (hash_table_objects_create):
* elhash.c (vars_of_elhash):
* symsinit.h:
Add memory-usage method to count the size of `hentries'.
* emacs.c (main_1):
Call new functions in elhash.c, frame.c at init.
* frame.c:
* frame.c (compute_frame_usage):
* frame.c (frame_memory_usage):
* frame.c (frame_objects_create):
* symsinit.h:
Add memory-usage method to count gutter display structures,
subwindow exposures.
* gc.c (gc_finish):
* lisp.h:
Declare finish_object_memory_usage_stats(), call it in gc_finish().
* lrecord.h (struct lrecord_implementation):
* lrecord.h (INIT_MEMORY_USAGE_STATS):
New value in implementation struct to track number of non-Lisp-memory
statistics. Computed in alloc.c.
