* alloc.c:
* alloc.c (assert_proper_sizing):
* alloc.c (c_readonly):
* alloc.c (malloced_storage_size):
* alloc.c (fixed_type_block_overhead):
* alloc.c (lisp_object_storage_size):
* alloc.c (inc_lrecord_stats):
* alloc.c (dec_lrecord_stats):
* alloc.c (pluralize_word):
* alloc.c (object_memory_usage_stats):
* alloc.c (Fobject_memory_usage):
* alloc.c (compute_memusage_stats_length):
* alloc.c (disksave_object_finalization_1):
* alloc.c (Fgarbage_collect):
* mc-alloc.c:
* mc-alloc.c (mc_alloced_storage_size):
* mc-alloc.h:
No functionality change here. Collect the allocations-statistics
code that was scattered throughout alloc.c into one place. Add
remaining section headings so that all sections have headings
clearly identifying the start of the section and its purpose.
Expose mc_alloced_storage_size() even when not MEMORY_USAGE_STATS;
this fixes build problems and is related to the export of
lisp_object_storage_size() and malloced_storage_size() when
non-MEMORY_USAGE_STATS in the previous change set.

22 Commentary: |
1231 | 23 |
24 Compile this file. Run it in the background giving it a command line | |
25 argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the | |
26 numbers assigned in /etc/services). | |
27 | |
28 Then start up a fresh (you're going to crash) XEmacs. Execute the following | |
29 | |
30 (defun lose (port) | |
31 (interactive "nUrk: ") | |
32 (require 'comint) | |
33 (while t | |
34 (condition-case e | |
35 (let* ((name "*lose*") | |
36 (b (get-buffer-create name))) | |
37 (switch-to-buffer b) | |
38 (comint-mode) | |
39 (comint-exec b name (cons "127.0.0.1" port) nil '()) | |
40 (process-send-string (get-buffer-process b) "\377\373\001") | |
41 (process-send-string (get-buffer-process b) "\377\373\001")) | |
42 (error (message "URK: %s" e)) (sit-for 1)))) | |
43 | |
44 Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway). | |
45 Note: the error messages are proper functioning. What should eventually | |
46 happen after a number of SIGPIPEs is that you get a SIGSEGV and life is | |
47 bad and XEmacs is dead. | |
