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.

This is the file .../info/dir, which contains the topmost node of the Info
hierarchy.  The first time you invoke Info you start off looking at that node,
which is (dir)Top.

Rather than adding new nodes to this directory (and this file) it is a better
idea to put them in a site-local directory, and then configure info to search
in that directory as well.  That way, you won't have to re-edit this file when
a new release of the editor comes out.

For example, you could add this code to .../lisp/site-start.el, which is
loaded before ~/.emacs each time the editor starts up:

  ;; find local info nodes
  (setq Info-directory-list
        (append Info-directory-list '("/private/info/")))

Then, when you enter info, a dir file like this one will be automatically
created and saved (provided you have write access to the directory).  The
contents of that file "/private/info/dir" will be appended to the contents of
this file.
