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.

line source
The files in this directory contain source code for the core XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files. Byte-compiled files are architecture-independent. Functions used only by files in this directory are considered "internal" and are subject to change at any time. All commands, and most functions with docstrings, are part of the exported API. In particular, it is considered good style to use the Common Lisp facilities provided in cl*.el. (Yes, that's ambiguous. Sorry, we don't have a full specification of the API, as the Lispref is chronically incomplete. Anything described in the Lispref is part of the API, of course.) Libraries which implement applications and enhancements are placed in the "packages", which are distributed separately from the core sources. #### Someone please update this. #### Partially updated 2001-08-25 by sjt. Needs more work. Mike? When XEmacs starts up, it adds certain directories in various hierarchies containing Lisp libraries to `load-path' (the list of directories to be searched when loading files). These are: this directory, its subdirectory ./mule (in Mule-enabled XEmacs only), the site-lisp directory (deprecated), and all the lisp/PACKAGE subdirectories of the xemacs-packages, mule-packages, and site-packages hierarchies. See setup-paths.el. #### Is the following true or relevant any more? bogus> Directories whose names begin with "-" or "." are not added to bogus> the default load-path. Some files which you might reasonably want to alter when installing or customizing XEmacs at your site are: paths.el You may need to change the default pathnames here, but probably not. This is loaded before XEmacs is dumped. site-init.el #### obsolete and removed? To pre-load additional libraries into XEmacs and dump them in the executable, load them from this file. Read the instructions in this file for a description of how to do this. site-load.el #### description is obsolete This is like site-init.el, but if you want the docstrings of your preloaded libraries to be kept in the DOC file instead of in the executable, you should load them from this file instead. To do this, you must also cause them to be scanned when the DOC file is generated by editing ../src/Makefile.in.in and rerunning configure. #### new semantics This file will preload additional libraries listed in ../site-packages and dump them into XEmacs. ../site-packages List of additional libraries read by site-load.el. site-start.el This is loaded each time XEmacs starts up, before the user's .emacs file. (Sysadmin must create.) Can be inhibited for a given invocation with `--no-site-file'. default.el This is loaded each time XEmacs starts up, after the user's .emacs file, unless .emacs sets the variable inhibit-default-init to t. (Sysadmin must create.) Can be inhibited for a given invocation with `-q'. version.el This contains the version information for XEmacs. ======================================================================== Original text follows: The files in this directory contain source code for the XEmacs facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc files are byte-compiled versions of the corresponding *.el files.
