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.
