Todd, > Am I missing a step here? I don't think so. Assuming the change set in the goodies directory was actually reliable. I simply copied it from 1.23, and if something obscure changed in the Interpreter's primitive dispatch since 1.23 then there's little hope of it working. > And, are you planning to compile and ship your 1.3 port with user > primitive support? Sure, if it's useful to somebody. I'll do the necessary stuff later tonight. Ian

Squeak mutlitple versions..."official/blessed" release questions...
by Serg Koren 18 Jan '98

18 Jan '98

I guess this leads me to ask... Since there seem to be many people making modifications to various images of Squeak; and some of these changes may affect portability, etc. is there a mechanism in place to consolidate these changes from image to image? It sounds from my short time on this group that a lot of neat stuff is being done by various people, but that these are pretty independant efforts. And if someone releases an image (such as I did for the Mac) how does it become "official" or "blessed"? I guess this is one reason I released my Mac version as 1.24SK (appending my initials) both to tell people it's not really an "official/blessed" version--if there is such a thing, and to avoid a versioning conflict with anyone else creating/working on a 1.24 version. If it helps and there's enough interest I'd be willing to keep and maintain a central site of 'fileOut's by OS type as well as links to people who have Squeak code to distribute. This could be used by people to pick/choose options they may want to load into their images that doesn't fall within an "official" release. There are a lot of sites out there that have good stuff but there doesn't seem to be a "central" site that links to them or organizes what is out there. Personally, I think the cross-platform portability of the code and base interepreter VMs is a key benefit of Squeak over other languages, and I'd be upset to see anyone compromise that. It's ok if someone creates a VM that's specific to an OS, but such modifications I think should fall under the platform specific code files within Interpreter support code. On the other hand any changes to the base interpreter code or non-hardware specific classes should be published so all images on all OSes can incorporate it. I guess one thing I'm disappointed with is that the Windows version of Squeak (I haven't played with the Unix ones) doesn't allow you to create all of the hardware specific code. That is, the WIndows version (at least the 1.3 release) still contains the primitive code in the goodies directory) under 1.23 and am having problems generating a new (1.3) VM with your user primitive change set. The interp.c you ship doesn't seem to have the user primitive support functions (I can't link my primitives against the current interpreter --- unresolved refs to the functions declared in sqUserPrims.h). So, I filed in the 1.23 user primitive change set (from goodies) into the 1.3 Squeak and generated a new interpreter with: Interpreter translate: 'interp.c' doInlines: true I then recompile the VM with the new interp.c and my user primitives. The resulting executable dies on start up with a Segmentation Fault in the BitBlit code. I haven't tried to debug it yet... But.... Am I missing a step here? And, are you planning to compile and ship your 1.3 port with user primitive support? -- Todd Coram (Maroc Ddot) tcoram(a)BLaCKSMITH.com | tcoram(a)pobox.com Sardonic slaughterer of sacred cows.

Squeak 1.3 for Unix
by Ian Piumarta 18 Jan '98

18 Jan '98

Unix Squeakers, The 1.3 version of Unix Squeak is now available at: ftp://alix.inria.fr/pub/squeak/unix/Squeak-1.3 It includes precompiled binaries for the following platforms: Intel/Linux Sparc/SunOS Sparc/Solaris Alpha/Digital Unix There are numerous improvements to the Unix support code, approximately as follows. support for X Shared Memory extensions rolled into the main sources + command-line option "-xshm" + env var "SQUEAK_XSHM" accompanied by support for asynchronous screen updates + command-line option "-xasync" + env var "SQUEAK_XASYNC" (effective only when xshm is enabled) support for asking the WM not to decorate window + command-line option "-notitle" + env var "SQUEAK_NOTITLE" which works by marking the Squeak window as a "transient for" the root window. I know, it's ugly. But it works fixed a race condition that sometimes caused Squeak and X to disagree about the size of the Squeak window at startup. Changed the default screen offset to 0@0 to cure a problem with initial sizing when user-placement is disabled enabled use of backing store to avoid repainting areas of the Pixmap on exposure, at the expense of server memory (this should be an option, but I'm too lazy [and I've got sooo much memory that I don't care ;)] -- it's easy to identify and disable the relevant lines in sqXWindow.c if you dislike it intensely) changed class/resource name to "Squeak" (no '!' at the end). WM configs (e.g. mine specifies NoTitle and NoBorder for "Squeak") may need to be updated as a result fixed timezone handling on (hopefully) all platforms, and for all locations (whether east or west of Greenwich meridian) -- many thanks to Richie Bielak for finally getting to the bottom of this! init code now switches off unaligned access reporting for DEC Alpha, so there's no more need to issue "uac p 0" from the shell before starting Squeak Unix and MacOS now share common versions of all header files (sq.h, sqConfig.h, and sqMachDep.h) "gnuify" script simplified to remove stuff that is irrelevant with the new Jitter (the original script is still there as "gnuify.trad", and the correct one will be chosen automatically if you're using GNU make) GNUmakefiles totally reworked, with a new top-level GNUmakefile that supports per-platform build directories. there are certainly problems that I've not yet spotted, but please bear with me: the new GNUmakefiles are a huge improvement over the old ones (especially for frequent rebuilds of VMs for multiple platforms ;o) Please let me know of any problems ASAP. I have unfortunately not had chance to test these binaries (1Mb of X bitmap takes a tad too long over a 22.6kbps modem link), but I have every reason to expect them to work. (I built VMs from essentially the same sources on Friday, and experienced no problems whatsoever.) Enjoy! Ian

Squeak 1.3 for Windows
by Andreas Raab 18 Jan '98

18 Jan '98

Fellow Squeakers, Squeak 1.3 is available for Win32 at http://isgwww.cs.uni-magdeburg.de/~raab/squeak/ ftp://ftp.cs.uni-magdeburg.de/pub/Smalltalk/free/squeak/win32/ in the image/1.30 directory and should show up at the UIUC archive soon. Besides the new features of Squeak 1.3 and some bug fixes (such as time zones and a net work fix fir PWS) there are couple of changes to the VM (quoting the ReleaseNotes): Notes for the 1.3 version of Squeak ----------------------------------- The directory contains two executables one simply called Squeak.exe the other one called SqueakJ.exe. The latter contains the dynamic translator (called Jitter) developed by Ian Piumarta. Note that this VM will _not_ run with images prior to 1.3! Also, there are now some preferences which can be set in the VM. You can access these from the system menu or by pressing the F2 key. The preferences currently include: * "Defer display update" Some people didn't like it therefore you can turn it now on and off (and compare the speed difference ;-) * "Run full screen" An idea of Reinier van der Loon (thanks!) allowing Squeak to occupy the whole screen. You won't notice that you're running Windows -- you feel like running SqueakOS ;-) Remember: Since you can't access the system menu in this mode you need to press F2 to make Squeak run in a window again! * "Show output console" Extremely helpful for VM developers. Opens a small window at the bottom showing the standard output messages. Thus, if you have any "printf"s in your C code you can see it right there. * "Display version information" Displays the version of the sqWin32Window.c file being used. Good for bug reports if the VM crashes. All of the above settings are stored in a file named "Squeak.ini" which can be found in your VMs directory. Note that the settings are immediately updated meaning that if you - start Squeak - Make it run full screen - quit Squeak WITHOUT saving - start Squeak again you will be in full screen mode - that's why you have to ------> REMEMBER THE F2 KEY! <------ If you don't, you can still modify/delete the Squeak.ini file.

Squeak 1.3 available for MacOS and Unix
by Ian Piumarta 17 Jan '98

17 Jan '98

Squeakers, I have placed copies of the Squeak 1.3 release in the following locations: ftp://alix.inria.fr/pub/squeak/mac/Squeak1.3.sea.bin [MacOS] ftp://alix.inria.fr/pub/squeak/unix/Squeak-1.3 [Unix] The MacOS version comes direct from "Squeak Central" this morning, and I am releasing it with Dan's blessing. The Unix version was compiled while I was logged in via a modem, so I have not had chance to test the binaries. Please let me know of any problems ASAP so that I can take the necessary action (read: take the relevant bus to INRIA ;). I have appended selected highlights from Dan's description of "what's new in 1.3". The full text of Dan's message can be found in the image, along with some new examples in the "welcome" window.. Andreas has a Win32 version ready, which he will be making available shortly on his FTP site. I will post release notes for the Unix version in a separate message. All versions of 1.3 should be appearing at UIUC (and its mirrors) shortly. Happy Squeaking! Regards, Ian Extracts from 1.3 release notes... New Virtual Machine With the release of Squeak 1.3 we are including two complete copies of the Squeak VM. The first, referred to generally as "Squeak VM 1.3" is simply an updated version of the standard bytecode interpreter that we have been using for the last year or so. The second, referred to as "Squeak Jitter 1.3", translates Squeak bytecodes on demand to a more efficient representation for faster execution. Support for Text Style and Links in Source Code Remember the discussion after OOPSLA about better documentation and navigation? Thanks to the work of Ted Kaehler, this version of Squeak allows creation of hyperlinks in text, and preserves them (and most text styles) in source code and class comments! New Sound and Music Facilities John Maloney has overhauled Squeak's sound synthesis code, improving the treatment of volume envelopes and left-right stereo pan, and greatly improving the variety of FM-generated timbres. As part of the same overhaul, Squeak can also now read MIDI files. A Complete WikiWiki Server Do you remember the e-mail discussion about a better medium for sharing progress on Squeak? Ward Cunningham offered up access to his WikiWiki server and things began to happen. Mark Guzdial picked up Georg Gollman's web server, made it more flexibile, and then he and his students built a WikiWiki server in about 15 pages of Squeak. We are indebted to Ward, Georg, and Mark for this delightful artifact. Numerous little bug fixes such as... Stack error on failure of primitveSomeInstance Bag asSet MethodDictionary do:

Hello fellow Squeakers!
by John-Reed Maffeo 17 Jan '98

17 Jan '98

Hello fellow Squeakers! I say that with pride now because last night I finally got a rough version of the TowersOfHanoi program to work!!! My work was based on a copy of the program that I downloaded from the Smalltalk archive at ftp.wustl.edu/ hanoi 16529 usenet/st80_pre4/hanoi.st Towers of Hanoi game -Dr Kevin Waite <kww(a)cs.glasgow.ac.uk> 2.5 Syntax changes were required in several methods and several methods needed to be moved to other classes. My effort was greatly aided by another program that I got to run prior to this which was also downloaded from the SA by ikp(a)cs.man.ac.uk which i can't find the reference to right now. MVC-Wires only needed a few syntax tweeks to get running. Once wires was running I was able to see what kind of changes I needed to make to get hanoi running. One thing that I have learned so far is the necessity to really know the classes and methods or else one is going to reinvent a lot of RoundThingsUsedForTransportation. <insert appropriate Squeat salutation here> John-Reed Maffeo
