fix various problems with allocation statistics, track overhead properly -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-03-20 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 showing the overhead used with each type, and add it into the grand total memory usage. src/ChangeLog addition: 2010-03-20 Ben Wing <ben@xemacs.org> * alloc.c: * alloc.c (init_lrecord_stats): * alloc.c (free_normal_lisp_object): * alloc.c (struct): * alloc.c (clear_lrecord_stats): * alloc.c (tick_lrecord_stats): * alloc.c (COUNT_FROB_BLOCK_USAGE): * alloc.c (COPY_INTO_LRECORD_STATS): * alloc.c (sweep_strings): * alloc.c (UNMARK_string): * alloc.c (gc_sweep_1): * alloc.c (finish_object_memory_usage_stats): * alloc.c (object_memory_usage_stats): * alloc.c (object_dead_p): * alloc.c (fixed_type_block_overhead): * alloc.c (lisp_object_storage_size): * emacs.c (main_1): * lisp.h: * lrecord.h: Export lisp_object_storage_size() and malloced_storage_size() even when not MEMORY_USAGE_STATS, to get the non-MEMORY_USAGE_STATS build to compile. Don't export fixed_type_block_overhead() any more. Some code cleanup, rearrangement, add some section headers. Clean up various bugs especially involving computation of overhead and double-counting certain usage in total_gc_usage. Add statistics computing the overhead used by all types. Don't add a special entry for string headers in the object-memory-usage-stats because it's already present as just "string". But do count the overhead used by long strings. Don't try to call the memory_usage() methods when NEW_GC because there's nowhere obvious in the sweep stage to make the calls. * marker.c (compute_buffer_marker_usage): Just use lisp_object_storage_size() rather than trying to reimplement it.

;;; Synched up with: FSF 19.34.

;;; Commentary:

;; This is loaded into a bare Emacs to create the blessmail script,
;; which (on systems that need it) is used during installation
;; to give appropriate permissions to movemail.
;;
;; It has to be done from lisp in order to be sure of getting the
;; correct value of rmail-spool-directory.

;;; Code:

;; These are no longer needed because we run this in emacs instead of temacs.
;; (message "Using load-path %s" load-path)
;; (load "paths.el")
;; It is not safe to load site-init.el here, because it might have things in it
;; that won't load properly unless all the rest of Emacs is loaded.
