NAME:             emacs

VERSION:          23.1

DESCRIPTION:      GNU Emacs editor

LICENSE:          GPLv3

BUGTRAQ:          solaris/utility/emacs

COMMENTS:         

This file contains information about the emacs package within the Userland

consolidation. Along with the comments in the Makefile, it documents any

deviations from standard Userland or emacs practice, as well as miscellaneous

information needed to understand how this component is put together.

- We patch the following changes to the emacs sources:

	buffer_menu.patch

	    Fixes an issue with GTK and the Buffers menu where the

	    menu contents is not updated to show the current buffers

	    and instead shows a stale list. I based these patches

	    on the official ones applied to the emacs development branch:

	    http://lists.gnu.org/archive/html/emacs-diffs/2009-09/msg00039.html

	sysmalloc.patch

	    Use the system malloc instead of the built in one

	dldump.patch

	    Use the native Solaris dldump() function (emacs/src/unexsol.c)

	    to produce the dumped emacs, rather than the generic ELF

	    code (emacs-22.1/src/unexelf.c).

	xft.patch

	    Patch configure script to provide necessary missing

	    libraries for the GTK version of emacs.

- Emacs can be built as either 32-bit or 64-bit, depending on the target

  machine. The benefit of a 64-bit emacs is that the size of the files it

  can handle is not limited to 128MB, as it is with the 32-bit version.

  For Solaris, we used to build both versions, using /usr/lib/isaexec to

  run the 64-bit version if possible, and the 32-bit version otherwise. Note

  that this was only done for the emacs binary itself, as there is no

  technical need for 64-bit versions of the ancillary programs that come

  with emacs (etags, emacsclient, etc).

  Fortunately, the vast majority of the files in an emacs tree are identical,

  regardless of the platform and/or word size, which makes this particularly

  easy to do.

  With Solaris 11, all kernels are 64-bit, and we therefore do not need

  the 32-bit executables. As such, we only supply 64-bit emacs binaries now,

  and the use of usr/lib/isaexec has been removed: This cuts the number of

  builds necessary in half, and also the binary package size. It also

  simplifies packaging, and the user's view of /usr/bin/emacs*.

  Note that we're installing a 64-bit objects in /bin, and

  usr/lib/emacs/$(COMPONENT_VERSION)/$(EMACS_ULEVDIR). The userland

  pkglint plugin considers these to be a "32-bit path". There is an

  RFE to suppress lint for specific attributes:

        Bug 17777 - it would be nice if pkglint could suppress specific

                    messages for specific actions

        https://defect.opensolaris.org/bz/show_bug.cgi?id=17777

  Until then, we simply assert that the whole action for those files is

  linted with

        pkg.linted=True

  This disables all lint checking for these items, so extra care is needed

  not to introduce some other error.

- There are three different toolkit options: None, Athena widgets

  (aka Xaw, or lucid), and gtk. It would be nice to only support gtk,

  but for purposes of minimization and user preference, we supply binaries

  for all three. We follow the Linux model in this regard. The Xaw and no-X

  versions are quite stable from release to release, so this isn't a large

  burden.

- We deliver the following packages:

	gnu-emacs - Everything you need to run emacs, except the

	    emacs binaries.

	gnu-emacs-gtk - Binaries for the X11 version using the GTK toolkit.

	gnu-emacs-no-x11 - Pure tty emacs binaries, built without

	    any X11 linkage. Ideal for headless server systems.

	gnu-emacs-x11 - Binaries for the X11 version using the Athena

	    widget (Xaw) toolkit.

	gnu-emacs-lisp - The compressed LISP files for which compiled

	    versions are delivered by gnu-emacs. These are only needed

	    for emacs developers and those who like to read source code.

  The core gnu-emacs package is required by all of the other packages.

  In turn, gnu-emacs requires at least one of the packages supplying an

  emacs binary to be installed.

- We do not ship any suid/sgid binaries for obvious security reasons.

  We do not install the files under /var/games/emacs. The reason for

  this is that we do not install update-game-score as setuid, and

  therefore the game files are not usable. This the same decision made

  by Debian, among others.

- The depend line in gnu-emacs.p5m requiring one of the three toolkit versions

  to be installed currently has the pkg.linted=true attribute set, pending

  the resolution of

        Bug 18202 - pkglint AttributeError when using require-any depend action
