[xemacs-hg @ 2003-02-20 08:19:28 by ben] check in makefile fixes et al Makefile.in.in: Major surgery. Move all stuff related to building anything in the src/ directory into src/. Simplify the dependencies -- everything in src/ is dependent on the single entry `src' in MAKE_SUBDIRS. Remove weirdo targets like `all-elc[s]', dump-elc[s], etc. mule/mule-msw-init.el: Removed. Delete this file. mule/mule-win32-init.el: New file, with stuff from mule-msw-init.el -- not just for MS Windows native, boys and girls! bytecomp.el: Change code inserted to catch trying to load a Mule-only .elc file in a non-Mule XEmacs. Formerly you got the rather cryptic "The required feature `mule' cannot be provided". Now you get "Loading this file requires Mule support". finder.el: Remove dependency on which directory this function is invoked from. update-elc.el: Don't mess around with ../src/BYTECOMPILE_CHANGE. Now that Makefile.in.in and xemacs.mak are in sync, both of them use NEEDTODUMP and the other one isn't used. dumped-lisp.el: Rewrite in terms of `list' and `nconc' instead of assemble-list, so we can have arbitrary forms, not just `when-feature'. very-early-lisp.el: Nuke this file. finder-inf.el, packages.el, update-elc.el, update-elc-2.el, loadup.el, make-docfile.el: Eliminate references to very-early-lisp. msw-glyphs.el: Comment clarification. xemacs.mak: Add macros DO_TEMACS, DO_XEMACS, and a few others; this macro section is now completely in sync with src/Makefile.in.in. Copy check-features, load-shadows, and rebuilding finder-inf.el from src/Makefile.in.in. The main build/dump/recompile process is now synchronized with src/Makefile.in.in. Change `WARNING' to `NOTE' and `error checking' to `error-checking' TO avoid tripping faux warnings and errors in the VC++ IDE. Makefile.in.in: Major surgery. Move all stuff related to building anything in the src/ directory from top-level Makefile.in.in to here. Simplify the dependencies. Rearrange into logical subsections. Synchronize the main compile/dump/build-elcs section with xemacs.mak, which is already clean and in good working order. Remove weirdo targets like `all-elc[s]', dump-elc[s], etc. Add additional levels of macros \(e.g. DO_TEMACS, DO_XEMACS, TEMACS_BATCH, XEMACS_BATCH, XEMACS_BATCH_PACKAGES) to factor out duplicated stuff. Clean up handling of "HEAP_IN_DATA" (Cygwin) so it doesn't need to ignore the return value from dumping. Add .NO_PARALLEL since various aspects of building and dumping must be serialized but do not always have dependencies between them (this is impossible in some cases). Everything related to src/ now gets built in one pass in this directory by just running `make' (except the Makefiles themselves and config.h, paths.h, Emacs.ad.h, and other generated .h files). console.c: Update list of possibly valid console types. emacs.c: Rationalize the specifying and handling of the type of the first frame. This was originally prompted by a workspace in which I got GTK to compile under C++ and in the process fixed it so it could coexist with X in the same build -- hence, a combined TTY/X/MS-Windows/GTK build is now possible under Cygwin. (However, you can't simultaneously *display* more than one kind of device connection -- but getting that to work is not that difficult. Perhaps a project for a bored grad student. I (ben) would do it but don't see the use.) To make sense of this, I added new switches that can be used to specifically indicate the window system: -x [aka --use-x], -tty \[aka --use-tty], -msw [aka --use-ms-windows], -gtk [aka --use-gtk], and -gnome [aka --use-gnome, same as --use-gtk]. -nw continues as an alias for -tty. When none have been given, XEmacs checks for other parameters implying particular device types (-t -> tty, -display -> x [or should it have same treatment as DISPLAY below?]), and has ad-hoc logic afterwards: if env var DISPLAY is set, use x (or gtk? perhaps should check whether gnome is running), else MS Windows if it exsits, else TTY if it exists, else stream, and you must be running in batch mode. This also fixes an existing bug whereby compiling with no x, no mswin, no tty, when running non- interactively (e.g. to dump) I get "sorry, must have TTY support". emacs.c: Turn on Vstack_trace_on_error so that errors are debuggable even when occurring extremely early in reinitialization. emacs.c: Try to make sure that the user can see message output under Windows (i.e. it doesn't just disappear right away) regardless of when it occurs, e.g. in the middle of creating the first frame. emacs.c: Define new function `emacs-run-status', indicating whether XEmacs is noninteractive or interactive, whether raw, post-dump/pdump-load or run-temacs, whether we are dumping, whether pdump is in effect. event-stream.c: It's "mommas are fat", not "momas are fat". Fix other typo. event-stream.c: Conditionalize in_menu_callback check on HAVE_MENUBARS, because it won't exist on w/o menubar support, lisp.h: More hackery on RETURN_NOT_REACHED. Cygwin v3.2 DOES complain here if RETURN_NOT_REACHED() is blank, as it is for GCC 2.5+. So make it blank only for GCC 2.5 through 2.999999999999999. Declare Vstack_trace_on_error. profile.c: Need to include "profile.h" to fix warnings. sheap.c: Don't fatal() when need to rerun Make, just stderr_out() and exit(0). That way we can distinguish between a dumping failing expectedly (due to lack of stack space, triggering another dump) and unexpectedly, in which case, we want to stop building. (or go on, if -K is given) syntax.c, syntax.h: Use ints where they belong, and enum syntaxcode's where they belong, and fix warnings thereby. syntax.h: Fix crash caused by an edge condition in the syntax-cache macros. text.h: Spacing fixes. xmotif.h: New file, to get around shadowing warnings. EmacsManager.c, event-Xt.c, glyphs-x.c, gui-x.c, input-method-motif.c, xmmanagerp.h, xmprimitivep.h: Include xmotif.h. alloc.c: Conditionalize in_malloc on ERROR_CHECK_MALLOC. config.h.in, file-coding.h, fileio.c, getloadavg.c, select-x.c, signal.c, sysdep.c, sysfile.h, systime.h, text.c, unicode.c: Eliminate HAVE_WIN32_CODING_SYSTEMS, use WIN32_ANY instead. Replace defined (WIN32_NATIVE) || defined (CYGWIN) with WIN32_ANY. lisp.h: More futile attempts to walk and chew gum at the same time when dealing with subr's that don't return.

This file is not meant to be proper documentation. See the file gnuserv.1 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.

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.
