NEWS: Emacs for VMS


- basis-4-synch-4 | 2005-05-26

  - Code Porting
  
	No changes.

  - Build Methodology

    - No more standalone TRADCPP

	The [.TRADCPP] subdirectory has been dropped.  It used to
	contain a standalone version of the GNU C preprocessor, hacked
	to work under VMS, and used by CONFIGURE.COM to as part of the
	flow for creating various DESCRIP.MMS files.

	Since the system C preprocessor does the job well enough, if
	passed the /STANDARD=VAXC switch, we no longer need TRADCPP.

    - TPU routines factored into [.VMS]CONFIGTAIL.TPU

	A large chunk of "in-line" TPU code from CONFIGURE.COM_IN now
	resides (cleaned up and in much more compact form) in the new
	file [.VMS]CONFIGTAIL.TPU.  These will probably be merged w/
	[.VMS]ROUTINES.TPU at some point.
	
  - Installation Methodology

	No changes.

  - GNU CVS Repository Integration

	Aside from DESCRIP.MMS and files that go into its creation,
	all [.LIB-SRC] merges are now complete.

	The patch filecount is now 73.


- basis-3-synch-3 | 2005-05-11

  - Code Porting

    - Bugfix: toggling marks in Dired recognizes non-filenames

	Previously, the marks would appear/disappear incorrectly for
	lines such as "Directory [FOO.BAR.BAZ]".

    - Bugfix: M-x compile no longer requires doubled double-quotes

	Before: write sys$output ""hello"",1,2,3,""there""
	Now:    write sys$output "hello",1,2,3,"there"

	This change also applies to M-x grep, for example:

	Before: fgrep -n ""GNU Emacs"" *.h *.c
	Now:    fgrep -n "GNU Emacs" *.h *.c

    - Bugfix: killing a shell buffer no longer leaves a zombie subproc

	Previously, when killing a (DCL) shell buffer, the child
	subprocess was not deleted straight away (although it would be
	deleted upon answering "yes" to the query on Emacs exit).

    - Bugfix: asynchronous timers now re-signal SIGALRM

	Apparently, VMS forgets the SIGALRM signal handler, so that
	alarms after the first one used to cause an AST fault (which
	typically would result in Emacs crashing).

    - Unixoid select(2) emulation revamped

	Generally, much more of the I/O has been integrated to use
	and/or hook into Emacs' event-processing internals, than before.
	These changes include a couple of (smallish) kludges to support
	the next item...

    - Frames can now be displayed using X Windows

	The logical DECW$DISPLAY needs to be set for this to work.
	To run on a tty in the presence of this logical, invoke Emacs
	with the "-nw" (no windowing system) switch, or alternatively,
	build Emacs w/o X support.

	This support makes use of Xlib directly, w/o any toolkits (see
	Build Methodology entry below).

  - Build Methodology

	Requires Autoconf for VMS version 1.104 or later.  (Please also
	try, and report bugs against, Autoconf for VMS version 1.105,
	which has support for "alternative" m4 programs.)

	You can now more-or-less safely pass "--with-x" (equivalent to
	"--with-x=YES") to the CONFIGURE.COM script.  The other options
	related to X support have yet to be tested -- YMMV!

	The CFLAGS are now:
		/DEBUG
		/WARNING=(DISABLE=(PTRMISMATCH1,UNDEFESCAP))
		/NAMES=SHORTENED
		/UNSIGNED_CHAR
		/EXTERN_MODEL=STRICT_REFDEF
	With the exception of the last one, all the others are different
	from before.  Notably, /NAMES=(AS_IS,SHORTENED) caused problems
	linking against the Xlib shareable image.

  - Installation Methodology

	No changes.

  - GNU CVS Repository Integration

	More small bits here and there (focus was on Code Porting).
	The patch filecount is now 95.


- basis-2-synch-2 | 2005-03-29

  - New convenience script available (in this directory): PREP-ZIP

  - Code Porting: no changes

  - Build Methodology

	Requires Autoconf for VMS version 1.104 or later.

	Much of [.VMS]*.COM is now offloaded to "autoconf --installvmslib";
	bindir, libdir and infodir are no longer manually initialized and
	AC_SUBSTituted (although many other variables are); bootstrapping
	flow was finally written (includes byte-compilation but not doc
	build); RUNTEMACS.COM was removed in favor of PRE-INST-EMACS.COM;
	the DONTCOMPILE list now includes two extra files that crash Emacs
	during bootstrap byte-compilation.

	Bootstrap+install *tested* (yay!); walltime approximately 4hrs.

	See README for updated build instructions.

  - Installation Methodology

	KEPTEDITOR.COM is now installed in $(pkglibdir), which is a
	child of $(libdir), which is a child of $(exec_prefix).  This
	change should be transparent to GNU_STARTUP.COM users (which
	should be most everyone).

	Installation no longer creates $(lockdir).

  - GNU CVS Repository Integration

	More small bits here and there (focus was on Build Methodology).
	I have received email from Richard Levitte and hope to be able
	to clear up some integration issues with his help.

	The patch filecount is 97 (down from 173 for basis-1-synch-1).


- basis-1-sync-1 | 2005-03-17

  - Code Porting

	Still missing X Windows support, however most other features are
	working w/o too much problem.

  - Build Methodology

	Requires Autoconf for VMS version 1.101 or later.

  - Installation Methodology

	Requires Autoconf for VMS version 1.101 or later.

  - GNU CVS Repository Integration

	Preliminary [.LIB-SRC] peripheral back- and forward-porting.
	Still need to figure out precisely status of Richard Levitte's
	contributions to GNU.
