cleanups to debug-print, try harder to make it work during GC -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-02-08 Ben Wing <ben@xemacs.org> * emacs.c: * emacs.c (assert_failed): Fix comments about when inhibit_non_essential_printing_operations is set and how used. Increment/decrement in assert_failed rather than just setting/resetting to avoid hosing things in case we're called when the value is already non-zero. Similarly increment/ decrement in_assert_failed. * gc.c (gc_prepare): * gc.c (gc_finish): Increment/decrement inhibit_non_essential_printing_operations rather than setting/resetting. * print.c: * print.c (debug_out): * print.c (write_string_to_alternate_debugging_output): * print.c (restore_inhibit_non_essential_conversion_operations): * print.c (debug_print_exit): * print.c (debug_print_enter): * print.c (debug_prin1): * print.c (debug_p4): * print.c (ext_print_begin): * print.c (ext_print_end): * print.c (external_debug_print): * print.c (debug_p3): * print.c (debug_backtrace): * print.c (debug_short_backtrace): * print.c (vars_of_print): Lots of cleanup. Fix debug_out() so it binds inhibit_non_essential_printing_operations around it to ensure no conversion. Remove many other places that set the same var since the lower-level functions now all do it. A few other places, add inhibit_non_essential_printing_operations bindings.Extract the code out that sets up and resets lots of bindings in debug_prin1() so that debug_backtrace() can use it, and rewrite it to use the new STORE_VOID_IN_LISP() rather than having to have a single static opaque structure holding all the bindings (and not handling reentrancy). Fix raw `char' to be `CIbyte' in the declaration of `alternate_do_string'. * signal.c (check_what_happened): Fix bug: Don't try to check for QUIT when inhibit_non_essential_printing_operations or we may screw things up if QUIT happens during debug printing.

;;; Synched up with: Not in FSF

;;; Commentary:

;; In FSF all of the custom loads are in a single `cus-load' file.
;; However, we have them distributed across directories, with optional
;; incremental loading.  Here we simply collect the whole set.


;;; Code:

(require 'custom)

(defun custom-add-loads (symbol list)
  "Update the custom-loads list of a symbol.
This works by adding the elements from LIST to the SYMBOL's
`custom-loads' property, avoiding duplicates.  Also, SYMBOL is
added to `custom-group-hash-table'."
  (let ((loads (get symbol 'custom-loads)))
    (dolist (el list)
      (unless (member el loads)
	(setq loads (nconc loads (list el)))))
    (put symbol 'custom-loads loads)
    (puthash symbol t custom-group-hash-table)))

(message "Loading customization dependencies...")

;; Garbage-collection seems to be very intensive here, and it slows
;; things down.  Nuke it.
(let ((gc-cons-threshold most-positive-fixnum))
