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.

/* Hey Emacs, this is -*- C -*- code! */ /* Synched up with: Not synched with FSF. */ /* Think twice before editing this file. Generated automatically by configure. The file startup.el guesses at reasonable values for load-path, exec-path, and lock-directory. This means that if you move emacs and its associated sub-tree to a different place in the filesystem, or to a different machine, you won't have to do anything for it to work. If you define the paths in this file then they will take precedence over any value generated by the heuristic in startup.el. The hardcoded paths will be checked to see if they are valid, in which case they will be used. Otherwise the editor will attempt to make its normal guess. See the NEWS file for a description of the heuristic used to locate the lisp and exec directories at startup time. If you are looking at this file because you are having trouble, then you would be much better off arranging for those heuristics to succeed than defining the paths in this file. ** Let me say that again. If you're editing this file, you're making ** a mistake. Re-read the section on installation in ../etc/NEWS. If it defines anything, this file should define some subset of the following: PATH_PREFIX The default value of `prefix-directory'. This is the default root for everything. PATH_LOADSEARCH The default value of `load-path'. PATH_EXEC The default value of `exec-directory' and `exec-path'. (exec-path also contains the value of whatever is in the PATH environment variable.) PATH_DATA The default value of `data-directory'. This is where architecture-independent files are searched for. PATH_LOCK The name of the directory that contains lock files with which we record what files are being modified in Emacs. This directory should be writable by everyone. If this is specified, the string must end with a slash! PATH_SUPERLOCK The name of the file !!!SuperLock!!! in the lock directory. You probably should let this default... PATH_INFO The default value of `Info-directory-list'. This is where info files are searched for. */
