Changes in Squeak 4.3.
There aren't any applications bundled with this release.
Instead of working on applications to bundle with the image,
core developers have been inspired by the Cog virtual machine
to look deeply into the image for things they wanted to change.
As a result, the image is becoming smaller, tidier, and nimbler.
There are five Welcome Workspaces in Squeak 4.3.
The second is called Future Directions:
- This image is ~15M. If you execute - Smalltalk unloadAllKnownPackages -
it will become ~10M
- A SqueakCore image is available at http://ftp.squeak.org/4.3
- A reasonable target is the creation of a smaller image,
which may be a task before the community
- A place to explore where to make reductions is likely the
removal/replacement of GUIs
- Once we have a smaller core image, we can employ Andreas Raab's memo [1]
on how to load code back into the image. This will be based on tests
delineating the separate responsibilities of core and application developers

set-up.
Changes in Squeak 4.1
This version combines the licence change occurring in the 4.0 release
with the development work that has been going on while the re-licensing
process took place.
Much of the work in this release has been focused on fundamental
improvements. Major achievements are the integration of Cog's
closure implementation, the improved UI look and feel,
the new anti-aliased fonts, the core library improvements,
and the modularity advances.
One key focus for this release was to address the issues that
have been known to frustrate developers using Squeak for the
first time. A much improved set of UI widgets, the new menu bar
including the fast search control, integrated help, improved
test coverage, more class and method comments, and integrated
syntax highlighting all make the system more accessible. The new
full closures, the new traits implementation, multiple
improvements to the collections and streams classes, the new
NumberParser hierarchy all help make development easier and
produce cleaner, faster code. Deploying your completed
applications will be made easier by the work done on making many
modules unloadable, and by support for other cleanup activities.
Squeak 4.0 is functionally equivalent to the previous Squeak 3.10.2 release
but licensed under the MIT license original parts remaining under the Apache
license.
Current development work will be released as 4.1 as soon as possible
following the release of 4.0.
pkgsrc changes:
- move machine-independent files into "share" hierarchy;
- set licence;
- fix homepage.
- correctly override the libtool used by the build.
- patch-ao: rearrange linker arguments so that vm/vm.a pulls in the libraries.
- patch-ap: fix building of npsqueak browser plugin (use cc as compiler. add
.so suffix to plugin)
- for whatever reason the plugins are now installed with .a and .so suffixes.
adjust PLISTs accordingly.
I can now at least start the vm again.
Based on patches by Brian de Alwis in PR pkg/37522.
Don't include aio.h in patch-ak, it is not needed.
Don't require bash for npsqueakrun yet. There is more work to do to
make the nsqueak plugin work.
Changes since 3.6-3:
*2006-10-10* 3.9-8 released. <release/RELEASE_NOTES_3.9-8> ALSA support
for Linux. Problems with iconv() fixed on Solaris.
*2006-04-24* 3.9-7 released. <release/RELEASE_NOTES_3.9-7>
Modifications to the mechanism the VM uses to relinquish the processor
for very short intervals to avoid high CPU loads while idling.
UUIDPlugin is now external to prevent the VM failing to run when libuuid
is missing or uncooperative. AioPlugin is bundled. Aliases are resolved
in path names on OS X.
*2006-04-19* 3.9-4 released. <release/RELEASE_NOTES_3.9-4> KeyUp events
are no longer reported for autorepeats under X11. Improvements to socket
latency. Security plugin now obeys SQUEAK_USERDIR if set. OSProcess and
XDisplayControl plugins updated from current distributions and bundled.
The 3.9 Unix VMs are now fully compatible with Croquet and will run both
Squeak and Croquet images. Additional plugins required for Croquet are
now supported and bundled in both source and binary releases:
CroquetPlugin, FloatMathPlugin and UUIDPlugin.
*2004-04-06* 3.7-7 released. <release/RELEASE_NOTES_3.7-7>
Documentation updated to reflect recent organisational changes. 'gnuify'
no longer requires gawk. Obscure bug in socket option lookup fixed.
NPSqueak changes from Bert (SQUEAK_USERDIR environment variable
overrides 'My Squeak', plus several bug fixes). Event code updated for
recent changes to event structures. README, manual page, and how-to
documentation updated and revised. Instructions for SVN checkout added.
'Easy build' route for checked-out SVN repository sources added. Browser
plugin now supports imageName and failureUrl attributes within <embed
...> tag. Preliminary support for XDND-based drag-and-drop (Gnome, KDE,
etc.) in the X11 display driver. New flag '-glxdebug <n>' prints OpenGL
diagnostics in X11 display driver. Interpreter should no longer crash
when loading image segments into memory above the 2GB boundary (thanks
to Ned Konz). Additional checks for bad external data in SocketPlugin.
Less inappropriate noise when probing for external plugins. Problems
preventing more than one external plugin from loading in Mac OS X fixed.
USE_TOOLS and any of "autoconf", "autoconf213", "automake" or
"automake14". Also, we don't need to call the auto* tools via
${ACLOCAL}, ${AUTOCONF}, etc., since the tools framework takes care
to symlink the correct tool to the correct name, so we can just use
aclocal, autoconf, etc.
Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
and enhancements since 3.0. Notably, display and sound plugins can now be
selected at run-time, and support is added for character set conversion.
This package also contains a driver for NetBSD native audio, by yours truly.
OSS audio requires a newer interface than NetBSD emulation supports, so that
doesn't build anymore on NetBSD, though it may with third party drivers. NAS
builds on NetBSD, but doesn't work. There are new display drivers which build
selectively on linux and MacOS, and a new audio driver for MacOS. I'm marking
this package ONLY_FOR_PLATFORM=NetBSD-*-*, though, mainly because the static
PLIST that the package presently has can't reflect any of that.
This closes PR pkg/17950.
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
Include a bugfix for lisp_LISP independently discovered by me that has
been pulled up to the automake-1-4 branch of automake cvs.
Changes are:
New in 1.4-p5:
* Allow AM_PROG_LIBTOOL again.
* Diagnose AC_CONFIG_HEADERS the same as AC_CONFIG_HEADER.
* Display distributed file list correctly in usage message.
* Allow numbers in macro names.
* Bugfixes.
New in 1.4-p4:
* Deal with configure.ac as well as configure.in -- this time for real!
* The version numbering system now allows three point version numbers,
such as 1.4.4, without thinking they are alpha release numbers.
New in 1.4-p3:
* Deal with configure.ac as well as configure.in.
* Don't complain if `version.texi' is included in multiple places.
New in 1.4-p2:
* Deal with AC_CONFIG_FILES from autoconf-2.50.
* Improvements to f77 support.
* DESTDIR now works for script targets.
* distcheck-hook works correctly.
New in 1.4-p1:
* The version numbering system now allows fork identifiers (such as
the p1 in this version of automake).
* Cope gracefully with various versions of libtool which may or may not
require ltconfig, ltcf-c.sh, ltcf-cxx.sh or ltcf-gcj.sh.
* Bugfixes.
Don't bother trying to compile for debugging in the pkgsrc Makefile.
"-fomit-frame-pointer" makes it impossible to debug on i386 anyway,
and it's easy enough to modify the package makefiles before building.
