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.

**** WARNING **** This file was never meant to be proper documentation, and now is bitrotted. See the file gnuserv.1 and/or the sources for more information. **** NOTE: This version of gnuserv has some enhancements over the original version distributed by Andy Norman. See the end of this file for more details. **** To install, copy gnuserv.el into a directory on your GNU Emacs load-path. Edit Makefile and change INCLUDES to point to the src directory underneath your emacs source tree (or make yourself a config.h file in this directory by hand, starting with config.h.proto as a first cut) and type: make This should compile the server and the two clients. Now put gnuserv, gnuclient and gnudoit in a directory that users have in their executable search paths. File : Description ---------------------------------------------------------------- Makefile : Makefile to build gnuserv LICENSE : GNU General License README : this file gnuclient.c : editor client C code gnudoit.c : eval client C code gnuserv.1 : gnuserv man page gnuserv.c : server C code gnuserv.el : server LISP code for GNU Emacs V18,V19, XEmacs/Lucid Emacs and Epoch V4 gnuserv.h : server/client C header file gnuslib.c : server/client C common code src.x11fns.diff : diffs to src/x11fns to raise window (for emacs18) config.h.proto : Use this file as the starting point for constructing a config.h if you don't have access to the one that was used when compiling your emacs. If you find *any* problems at all with gnuserv, or you can think of better ways of doing things (especially remote file access), please e-mail me at one of the addresses below. ange@hplb.hpl.hp.com ange@hpl.hp.co.uk ...!hplabs!hplb!ange ...!ukc!hplb!ange This version of gnuserv has been enhanced by a number of people, including Bob Weiner <weiner@mot.com>, Darrell Kindred <dkindred@cmu.edu>, Arup Mukherjee <arup@cmu.edu>, and Ben Wing <ben@xemacs.org>. The modifications are basically as follows: Bob Weiner: Integrated support for several versions of emacs. New requests from gnuclient cause the creation of new frames. Removed the restriction on the length of the string passed to gnudoit. Later added a server-done-function variable to control what happens to a buffer after the user is done with it. Mods to each of the .c files as well as gnuserv.el. Darrell Kindred: Removed the restriction on the length of the string returned from a gnudoit request, for the purposes of unix/internet sockets. Allow the gnudoit request to be read from stdin if it's not specified on the command line. Internet sockets are not opened unless the GNU_SECURE variable is specified. Unix sockets are created in a protected ancestral directory, since many Unix variants don't enforce socket permissions properly. An internet socket accepting local connections is not opened by default because this would make it possibly to override all security on the unix socket. See the man page for details. Unless told to do otherwise by a command-line argument, gnuclient and gnudoit now try to open a unix socket by default if support for them was compiled in. Mods to each of the .c files and to gnuserv.el. Arup Mukherjee: Removed the restriction on the length of the string returned from a gnudoit request, for the purposes of sysv ipc. Added support for the "gnuserv-frame" variable allowing you to specify control whether or not new screens are created in response to each gnuclient request. Made a number of other bugfixes and changes to the lisp part of the code, allowing gnuserv to work properly with newer emacs versions. All the changes are listed in the changelog at the beginning of gnuserv.el. Also fixed up the man page to reflect the new gnuserv features. On HPs, stopped the "-r" parameter (in gnuclient) from defaulting to /net/<remotehost>. Not all installations want this, and it's much harder to debug when things stop working. Changed the man page to reflect this. Mods to each of the .c files, gnuserv.el and gnuserv.1 More recently - added Xauth(1X11)-style authentication to gnuserv (as of version 2.1). Although the code is completely new, credit is due to Richard Caley <rjc@cogsci.edinburgh.ac.uk> ... he wrote a prototype implementation from which I borrowed the basic mechanism for hooking Xauth into gnuserv. Ben Wing: Added gnuattach.
