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.
