[xemacs-hg @ 2002-05-28 08:44:22 by ben] merge my stderr-proc ws make-docfile.c: Fix places where we forget to check for EOF. code-init.el: Don't use CRLF conversion by default on process output. CMD.EXE and friends work both ways but Cygwin programs don't like the CRs. code-process.el, multicast.el, process.el: Removed. Improvements to call-process-internal: -- allows a buffer to be specified for input and stderr output -- use it on all systems -- implement C-g as documented -- clean up and comment call-process-region uses new call-process facilities; no temp file. remove duplicate funs in process.el. comment exactly how coding systems work and fix various problems. open-multicast-group now does similar coding-system frobbing to open-network-stream. dumped-lisp.el, faces.el, msw-faces.el: Fix some hidden errors due to code not being defined at the right time. xemacs.mak: Add -DSTRICT. ================================================================ ALLOW SEPARATION OF STDOUT AND STDERR IN PROCESSES ================================================================ Standard output and standard error can be processed separately in a process. Each can have its own buffer, its own mark in that buffer, and its filter function. You can specify a separate buffer for stderr in `start-process' to get things started, or use the new primitives: set-process-stderr-buffer process-stderr-buffer process-stderr-mark set-process-stderr-filter process-stderr-filter Also, process-send-region takes a 4th optional arg, a buffer. Currently always uses a pipe() under Unix to read the error output. (#### Would a PTY be better?) sysdep.h, sysproc.h, unexfreebsd.c, unexsunos4.c, nt.c, emacs.c, callproc.c, symsinit.h, sysdep.c, Makefile.in.in, process-unix.c: Delete callproc.c. Move child_setup() to process-unix.c. wait_for_termination() now only needed on a few really old systems. console-msw.h, event-Xt.c, event-msw.c, event-stream.c, event-tty.c, event-unixoid.c, events.h, process-nt.c, process-unix.c, process.c, process.h, procimpl.h: Rewrite the process methods to handle a separate channel for error input. Create Lstreams for reading in the error channel. Many process methods need change. In general the changes are fairly clear as they involve duplicating what's used for reading the normal stdout and changing for stderr -- although tedious, as such changes are required throughout the entire process code. Rewrote the code that reads process output to do two loops, one for stdout and one for stderr. gpmevent.c, tooltalk.c: set_process_filter takes an argument for stderr. ================================================================ NEW ERROR-TRAPPING MECHANISM ================================================================ Totally rewrite error trapping code to be unified and support more features. Basic function is call_trapping_problems(), which lets you specify, by means of flags, what sorts of problems you want trapped. these can include -- quit -- errors -- throws past the function -- creation of "display objects" (e.g. buffers) -- deletion of already-existing "display objects" (e.g. buffers) -- modification of already-existing buffers -- entering the debugger -- gc -- errors->warnings (ala suspended errors) etc. All other error funs rewritten in terms of this one. Various older mechanisms removed or rewritten. window.c, insdel.c, console.c, buffer.c, device.c, frame.c: When creating a display object, added call to note_object_created(), for use with trapping_problems mechanism. When deleting, call check_allowed_operation() and note_object deleted(). The trapping-problems code records the objects created since the call-trapping-problems began. Those objects can be deleted, but none others (i.e. previously existing ones). bytecode.c, cmdloop.c: internal_catch takes another arg. eval.c: Add long comments describing the "five lists" used to maintain state (backtrace, gcpro, specbind, etc.) in the Lisp engine. backtrace.h, eval.c: Implement trapping-problems mechanism, eliminate old mechanisms or redo in terms of new one. frame.c, gutter.c: Flush out the concept of "critical display section", defined by the in_display() var. Use an internal_bind() to get it reset, rather than just doing it at end, because there may be a non-local exit. event-msw.c, event-stream.c, console-msw.h, device.c, dialog-msw.c, frame.c, frame.h, intl.c, toolbar.c, menubar-msw.c, redisplay.c, alloc.c, menubar-x.c: Make use of new trapping-errors stuff and rewrite code based on old mechanisms. glyphs-widget.c, redisplay.h: Protect calling Lisp in redisplay. insdel.c: Protect hooks against deleting existing buffers. frame-msw.c: Use EQ, not EQUAL in hash tables whose keys are just numbers. Otherwise we run into stickiness in redisplay because internal_equal() can QUIT. ================================================================ SIGNAL, C-G CHANGES ================================================================ Here we change the way that C-g interacts with event reading. The idea is that a C-g occurring while we're reading a user event should be read as C-g, but elsewhere should be a QUIT. The former code did all sorts of bizarreness -- requiring that no QUIT occurs anywhere in event-reading code (impossible to enforce given the stuff called or Lisp code invoked), and having some weird system involving enqueue/dequeue of a C-g and interaction with Vquit_flag -- and it didn't work. Now, we simply enclose all code where we want C-g read as an event with {begin/end}_dont_check_for_quit(). This completely turns off the mechanism that checks (and may remove or alter) C-g in the read-ahead queues, so we just get the C-g normal. Signal.c documents this very carefully. cmdloop.c: Correct use of dont_check_for_quit to new scheme, remove old out-of-date comments. event-stream.c: Fix C-g handling to actually work. device-x.c: Disable quit checking when err out. signal.c: Cleanup. Add large descriptive comment. process-unix.c, process-nt.c, sysdep.c: Use QUIT instead of REALLY_QUIT. It's not necessary to use REALLY_QUIT and just confuses the issue. lisp.h: Comment quit handlers. ================================================================ CONS CHANGES ================================================================ free_cons() now takes a Lisp_Object not the result of XCONS(). car and cdr have been renamed so that they don't get used directly; go through XCAR(), XCDR() instead. alloc.c, dired.c, editfns.c, emodules.c, fns.c, glyphs-msw.c, glyphs-x.c, glyphs.c, keymap.c, minibuf.c, search.c, eval.c, lread.c, lisp.h: Correct free_cons calling convention: now takes Lisp_Object, not Lisp_Cons chartab.c: Eliminate direct use of ->car, ->cdr, should be black box. callint.c: Rewrote using EXTERNAL_LIST_LOOP to avoid use of Lisp_Cons. ================================================================ USE INTERNAL-BIND-* ================================================================ eval.c: Cleanups of these funs. alloc.c, fileio.c, undo.c, specifier.c, text.c, profile.c, lread.c, redisplay.c, menubar-x.c, macros.c: Rewrote to use internal_bind_int() and internal_bind_lisp_object() in place of whatever varied and cumbersome mechanisms were formerly there. ================================================================ SPECBIND SANITY ================================================================ backtrace.h: - Improved comments backtrace.h, bytecode.c, eval.c: Add new mechanism check_specbind_stack_sanity() for sanity checking code each time the catchlist or specbind stack change. Removed older prototype of same mechanism. ================================================================ MISC ================================================================ lisp.h, insdel.c, window.c, device.c, console.c, buffer.c: Fleshed out authorship. device-msw.c: Correct bad Unicode-ization. print.c: Be more careful when not initialized or in fatal error handling. search.c: Eliminate running_asynch_code, an FSF holdover. alloc.c: Added comments about gc-cons-threshold. dialog-x.c: Use begin_gc_forbidden() around code to build up a widget value tree, like in menubar-x.c. gui.c: Use Qunbound not Qnil as the default for gethash. lisp-disunion.h, lisp-union.h: Added warnings on use of VOID_TO_LISP(). lisp.h: Use ERROR_CHECK_STRUCTURES to turn on ERROR_CHECK_TRAPPING_PROBLEMS and ERROR_CHECK_TYPECHECK lisp.h: Add assert_with_message. lisp.h: Add macros for gcproing entire arrays. (You could do this before but it required manual twiddling the gcpro structure.) lisp.h: Add prototypes for new functions defined elsewhere.

Usage: configure [--OPTION[=VALUE] ...] [CONFIGURATION]

Set compilation and installation parameters for XEmacs, and report.

Note that for most of the following options, you can explicitly enable
them using `--OPTION=yes' and explicitly disable them using `--OPTION=no'.
This is especially useful for auto-detected options.
The option `--without-FEATURE' is a synonym for `--with-FEATURE=no'.

Options marked with a (*) are auto-detected.

Many features require external packages to be installed first.
Get them from ftp://ftp.xemacs.org/pub/xemacs/aux.

Use colons (or quoted spaces) to separate directory names in option
values which are PATHs (i.e. lists of directories).

The results of configure tests are saved in config.log, which is useful
for diagnosing problems.


General options:

--help                  Issue this usage message.
--verbose               Accepted but ignored.
--extra-verbose         Display more information, useful for debugging.


Compilation options:

--compiler=PROG         C compiler to use
--xemacs-compiler=PROG  compiler to use to compile just the xemacs executable
--with-gcc (*)          Use GCC to compile XEmacs.
--cflags=FLAGS          Compiler flags (such as -O)
--cpp=PROG              C preprocessor to use (e.g. /usr/ccs/lib/cpp or cc -E)
--cppflags=FLAGS        C preprocessor flags (e.g. -I/foo or -Dfoo=bar)
--libs=LIBS             Additional libraries (e.g. -lfoo)
--ldflags=FLAGS         Additional linker flags (e.g. -L/foo)
--site-includes=PATH    List of directories to search first for header files
--site-libraries=PATH   List of directories to search first for libraries
--site-prefixes=PATH    List of directories to search for include/ and lib/
                        subdirectories, just after 'site-includes' and
                        'site-libraries'
--site-runtime-libraries=PATH
                        List of ALL directories to search for dynamically
                        linked libraries at run time
--dynamic=yes           Link dynamically if supported by system.
--dynamic=no            Force static linking on systems where dynamic
                        linking is the default.
--srcdir=DIR            Look for the XEmacs source files in DIR.
                        Works best when using GNU Make.


Installation options:

--prefix=DIR            Install files below DIR.  Defaults to `/usr/local'.
--with-prefix=no        Don't compile the value of --prefix into the
                        executable.


Window-system options:

--with-gtk              Support GTK on the X Window System. (EXPERIMENTAL)
--with-gnome            Support GNOME on the X Window System. (EXPERIMENTAL)

--x-includes=DIR        Search for X header files in DIR.
--x-libraries=DIR       Search for X libraries in DIR.
--with-msw (*)          Support MS Windows as a window system (only under
                        Cygwin and MinGW).  `--with-msw=no' may be needed on
                        *nix systems with Wine installed.
--with-toolbars=no      Don't compile with any toolbar support.
--with-wmcommand=no     Compile without realized leader window which will
                        keep the WM_COMMAND property.
--with-athena=TYPE      Use TYPE Athena widgets
                        (xaw, 3d, next, 95, or xpm)
--with-menubars=TYPE    Use TYPE menubars (lucid, motif, or no).  The Lucid
                        widgets emulate Motif (mostly) but are faster.
                        *WARNING*  The Motif menubar is currently broken.
--with-scrollbars=TYPE  Use TYPE scrollbars
                        (lucid, motif, athena, or no).
--with-dialogs=TYPE     Use TYPE dialog boxes (lucid, motif, athena, or no).
                        Lucid menubars and scrollbars are the default.
                        Motif dialog boxes will be used if Motif can be found.
--with-widgets=TYPE     Use TYPE widgets (lucid, motif, athena, or no).
                        Motif widgets will be used if Motif can be found.
                        Other widget types are currently unsupported.
--with-dragndrop        Compile in the generic drag and drop API. This is
                        automatically added if one of the drag and drop
                        protocols is found (currently CDE, OffiX, MSWindows,
                        and GTK).
                        *WARNING*  The Drag'n'drop support is under development
                                   and is considered experimental.
--with-cde              Compile in support for CDE drag and drop.
--with-offix            Compile in support for OffiX drag and drop.
                        *WARNING*  If you compile in OffiX, you may not be
                                   able to use multiple X displays success-
                                   fully.  If the two servers are from
                                   different vendors, the results may be
                                   unpredictable.
--with-xmu=no (*)       For those unfortunates whose vendors don't ship Xmu.
--external-widget       Compile with external widget support.


TTY (character terminal) options:

--with-tty=no           Don't support ttys.
--with-ncurses (*)      Use the ncurses library for tty support.
--with-gpm (*)          Compile in GPM mouse support for ttys.


Image options:

--with-xpm (*)          Compile with support for XPM images.  PRACTICALLY
                        REQUIRED.  Although this library is nonstandard and
                        a real hassle to build, many basic things (e.g.
                        toolbars) depend on it, and you will run into
                        many problems without it.
--with-png (*)          Compile with support for PNG images.  Recommended
                        because the images on the About page are not viewable
                        without it.
--with-jpeg (*)         Compile with support for JPEG images.  Useful if
                        you are using a mail, news reader, or web browser
                        in XEmacs, so that JPEG images can be displayed.
--with-tiff (*)         Compile with support for TIFF images.  Possibly
                        useful, for the same reason as JPEG images.
--with-xface (*)        Compile with support for X-Face mail headers.
                        Requires the compface package.  Of doubtful
                        usefulness.
--with-gif=no           Compile without the (builtin) support for GIF images.


Sound options:

--with-sound=TYPE[,TYPE[,...]] (*) Compile with sound support.
                        Valid types are `native', `nas' and `esd'.
                        Prefix a type with 'no' to disable.
                        The first type can be `none' or `all'.  `none' means
                        `nonative,nonas,noesd'.  `all' means `native,nas,esd'.
                        Later options override earlier ones for the same TYPE.
                        The default is to autodetect all sound support.
--native-sound-lib=LIB  Native sound support library.  Needed on Suns
                        with `--with-sound=native,nas' because both sound
                        libraries are called libaudio.


Database options:

--with-database=TYPE (*) Compile with database support.  Valid types are
                        `no' or a comma-separated list of one or more
                        of `berkdb' and either `dbm' or `gnudbm'.
--with-ldap (*)         Compile with support for the LDAP protocol.
--with-postgresql (*)   Compile with support for the PostgreSQL RDBMS.


Mail options:

--mail-locking=TYPE (*) Specify the locking to be used by movemail to prevent
                        concurrent updates of mail spool files. Valid types
                        are `lockf', `flock', `dot', `locking' or `mmdf'.
--with-pop              Support POP for mail retrieval.
--with-kerberos         Support Kerberos-authenticated POP.
--with-hesiod           Support Hesiod to get the POP server host.


Additional features:

--with-tooltalk (*)     Support the ToolTalk IPC protocol.
--with-workshop         Support the Sun WorkShop (formerly Sparcworks)
                        development environment.
--with-socks            Compile with support for SOCKS (an Internet proxy).
--with-dnet (*)         Compile with support for DECnet.
--with-modules          Compile in experimental support for dynamically
                        loaded libraries (Dynamic Shared Objects).
--with-netinstall       Compile in support for installation over the internet.
                        Only functional on the MS Windows platforms.
--with-ipv6-cname=yes   Try IPv6 information first when canonicalizing host
                        names.  This option has no effect unless system
                        supports getaddrinfo(3) and getnameinfo(3).
--with-site-lisp=yes    Allow for a site-lisp directory in the XEmacs hierarchy
                        searched before the installation packages.
--with-site-modules=no  Disable site-modules directory in the XEmacs hierarchy,
                        which is searched before the installation modules.
--package-path=PATH     Directories to search for packages to dump with xemacs.
                        PATH splits into three parts separated by double
                        colons (::), an early, a late, and a last part,
                        corresponding to their position in the various
                        system paths:  The early part is always first,
                        the late part somewhere in the middle, and the
                        last part at the very back.
                        Only the late part gets seen at dump time.
                        If PATH has only one component, that component
                        is late.
                        If PATH has two components, the first is
                        early, the second is late.
--infodir=DIR           Directory to install XEmacs Info manuals and dir in.
--infopath=PATH         Directories to search for Info documents, info dir
                        and localdir files in case run-time searching
                        for them fails.
--moduledir=DIR         Directory to install dynamic modules in.
--pdump                 New, experimental, don't-sue-me-if-your-house-
                        collapses-and-your-wife-leaves-you, portable dumper.
			(Actually, not as experimental or non-working as
			Olivier claims.  Works quite well, in fact.)
--with-default-eol-detection
                        Turns on by default auto-detection of end-of-line type
			when reading a file.  Applies to those platforms where
			auto-detection is off by default (non-Mule Unix).  Has
			no effect otherwise.


Internationalization options:

--with-mule             Compile with Mule (MUlti-Lingual Emacs) support,
                        needed to support non-Latin-1 (including Asian)
                        languages.
--with-xim=xlib         Compile with support for X input methods,
--with-xim=motif (*)    Used in conjunction with Mule support.
                        Use either raw Xlib to provide XIM support, or
                        the Motif XmIm* routines (when available).
                        NOTE:  On some systems bugs in X11's XIM support
                        will cause XEmacs to crash, so by default,
                        no XIM support is compiled in, unless running
                        on Solaris and the XmIm* routines are detected.
--with-canna (*)        Compile with support for Canna (a Japanese input method
                        used in conjunction with Mule support).
--with-wnn (*)          Compile with support for Wnn (a multi-language input
                        method used in conjunction with Mule support).
--with-wnn6 (*)         Compile with support for the commercial package Wnn6.
--with-i18n3            Compile with I18N level 3 (support for message
                        translation).  This doesn't currently work.
--with-xfs              Compile with XFontSet support for internationalized
                        menubar.  Incompatible with `--with-xim=motif'.
                        `--with-menubars=lucid' (the default) is desirable.


Debugging options:

--debug                 Compile with support for debugging XEmacs.
                        (Causes code-size increase and little loss of speed.)
--error-checking=TYPE[,TYPE]...
                        Compile with internal error-checking added.
                        Causes noticeable loss of speed.  Valid types
                        are extents, bufpos, malloc, gc, typecheck.
--error-checking=none   Disable all internal error-checking (the default).
--error-checking=all    Enable all internal error-checking.
--memory-usage-stats    Compile with additional code to allow you to
                        determine what XEmacs's memory is being used
                        for.  Causes a small code increase but no loss
                        of speed.  Normally enabled when --debug is given.
--quick-build           Speed up the build cycle by leaving out steps where
                        XEmacs will still work (more or less) without them.
                        Potentially dangerous if you don't know what you're
                        doing. This (1) doesn't garbage-collect after loading
                        each file during dumping, and (2) doesn't
                        automatically rebuild the DOC file. (Remove it by hand
                        to get it rebuilt.)
--use-union-type        Enable or disable use of a union, instead of an
                        int, for the fundamental Lisp_Object type; this
                        provides stricter type-checking.  Only works with
                        some systems and compilers.
--with-quantify         Add support for performance debugging using Quantify.
--with-purify           Add support for memory debugging using Purify.


Other options:

--rel-alloc             Use the relocating allocator (default for this option
                        is system-dependent).
--with-dlmalloc         Control usage of Doug Lea malloc on systems that have
                        it in the standard C library (default is to use it if
                        it is available).
--with-system-malloc    Force use of the system malloc, rather than GNU malloc.
--with-debug-malloc     Use the debugging malloc package.
--with-clash-detection  Use lock files to detect multiple edits of the same
                        file.  The default is to do clash detection.

You may also specify any of the `path' variables found in Makefile.in.in,
including --bindir, --libdir, --docdir, --lispdir, --sitelispdir,
--datadir, --infodir, --mandir and so on.  Note that we recommend
against explicitly setting any of these variables.  See the INSTALL
file for a complete list plus the reasons we advise not changing them.

If successful, configure leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status.

The configure script also recognizes some environment variables, each
of which is equivalent to a corresponding configure flag.  Configure
flags take precedence over environment variables, if both are specified.
