Trying out morphic
by Juan Cires Martinez 27 May '98

27 May '98

I am trying to move a morphic world from 1.31 to 2.0 and I have the following problem: when I read morphs from file, I get a "class is not in structures list" error. The className is DiskProxy. Another related question: is it possible to recreate the morphic world using the filedOut model? Thanks, Juan.

Start the PWS in a normal VM, snapshot the image while the server is running, then load the image into the headless VM. I don´t know about the PWS but with my WebServer the snapshot has to be done through the web to ensure proper socket handling. Georg ---- Dipl.Ing.

I can only do Saturday -- kids in school, etc. I would love a reunion at Zott's (aka Rosotti's Alpine Beer Garden in Portola Valley (right next to Palo Alto), CA). I'm lining up a sitter for the dogs, and I think the car will do the 4 hours down to sea level. So, in an attempt to crystallize this plan, I will commit to being at Zotts around 1pm on Saturday the 30th, ready for a good burger, a tall pitcher, and some appropriately aimless conversation.

Alex, > Another thing I'm playing with is the headless vm. Is there a method > that gets called after the image has been loaded? remember, we're in Smalltalk ;-) Just open a workspace, enter Smalltalk snapShot: true andQuit: true. PWS serveOnPort: 8080 loggingTo: 'pws.log' then execute this as one big doIt. The image will be saved and the next time it comes up it will immediately start the PWS.

startup of headless vm
by Lex Spoon 27 May '98

SystemDicitonary>>processStartUpList. I can personally vouch it works just great for the purpose you describe :) Add 'PWS startUp' to the end of this method, and write an appropriate startUp routine in PWS class.

---------- Desde: Alejandro F. Reimondo[SMTP:alereimondo@sugarweb.com] Enviado el: Miércoles 27 de Mayo de 1998 07:48 Para: 'Squeak List' Asunto: sqAPIs VM for version 2.0 Hi ! I've built the VM for Squeak 2.0 under windows with sqAPIs support. You can find it at http://www.sugarWeb.com/Miniatures/Files/sqAPIs/sqAPIv20.zip The Smalltalk source code is 100% compatible with the new VM. Cheers, Ale.

....see URL ftp://ftp.create.ucsb.edu/pub/Squeak/2.0 There's an un-packed set of files there with separate VM, VI, src, and changes. It is soon to be joined by STP's personal image and Siren 2.0.

Re: Updates 'R' Us on Win95
by Andreas Raab 27 May '98

27 May '98

> Do you mind to share with us what is the cause of the problem? If it is too > long to describe, then don't waste your time. It's quite tricky but ok, I'll try it. It's actually a *great* example why Smalltalk is so much better than C/C++. As you may know, I'm re-opening the standard output and error for redirecting everything from there into a file so that it can be shown upon Squeak exiting. For this, I created a temporary file and reopened the standard and error output. Now, the bug was that got the order wrong (*don't* ask me why ;-)) so that I re-opened the file before trying to get temporary file name. This results in actually *freeing* of the handle since the file could not be created. So far, the standard handle was just not there (btw, I only did this wrong with the stderr handle so all stuff going to stdout went ok). Now comes the funny stuff: *Because* I had actually closed the standard handle, the system (e.g., the run-time library) felt free to re-use the resources associated with it. In other words, when a file was opened there was a certain chance that it would be stored in the place normally reserved for the standard handle. This *can* lead to all sorts of unforeseen effects but since most files are closed upon exiting the image there is usually no problem with it (and that's exactly why you could exit Squeak by using the desktop menu). However, the order of operations when doing *particular* this update led to the effect that during fileIn of the update the changes file was stored in the place of the standard handle when you tried to exit through the close button. And then the cleanup goes wrong since it does not expect to have a *huge* error output. So again, thanks for finding the "right" order of operation ;-) That's it.

Many thanks -- to you, and you, and you...
by Dan Ingalls 26 May '98

Folks - I said that we would have 2.0 out on Friday the 22nd, and we did exactly that. However, now that I've had a chance to sleep a little, I would like to add some appropriate commentary. You should know that the Squeak team ran utterly flat out for at least the month leading up to this release. The picture when we finally shipped was the geographically distributed equivalent of a computer with FTP on the screen, surrounded by 4 bodies collapsed on the floor with x's where there eyes should be. So, first of all, Ted, John, and Scott, thank you, each, for dedication that can only be explained by love for what you do. For me personally, I simply didn't have the energy left to complete an appropriate acknowledgement after storing the files out (and giving you the wrong server reference ;-). What I wanted to say, though, boils down to this: None of this would be the same without you... In particular, the promise of Squeak's remarkable cross-platform compatibility has only been realized because of continuing hard work outside Squeak Central by Andreas Raab and Ian Piumarta. Andreas has been an invaluable collaborator on matters related to the Win32 port. In particular, he worked out how to implement MIDI, serial port access, full screen mode, high-resolution timer access, and printing support on the Win32 platforms, as well as helping with the design of these primitives. Ian has always kept the UNIX ports up to date, and continues to move Jitter toward a point where it can take on the role of mainstreamVM with a significant performance boost. The ftp archives and e-mail distribution that tie this community together are fostered by significant commitments from Stephen Pope, John Brant and Ralph Johnson. The WikiWiki servers that have become central to our collaboration and public appearance are the result of work by Ward Cunningham, Georg Gollman, and Mark Guzdial and his students Many improvements to Squeak numeric support have been suggested or actually supplied by a savvy crew that includes Tim Olson, Leandro Caniglia, Wim Boot, Hans-Martin Mosner, and David Smith. This release includes fledgling support for MIDI. Thanks to Stephen Pope for proposing a simple primitive interface that is sufficient to support basic MIDI on a wide range of hardware, while being upward compatible with the more extensive set of primitives needed for his SIREN computer music workbench. This work is not yet complete, but it is an exciting beginning. Our original intention in releasing the beta version of Squeak 2.0 was simply to give people a chance to discover serious incompatibilities before the actual release. However this process was transformed by a number of folks who tested the image, tracked our updates, and contributed many bug reports and a number of bug fixes. Special credit in this area goes to Bill Dargel, Reinier van Loon, Gerardo Richarte, Tom Morgan, Georg Gollmann, Luciano Notarfrancesco, and Tim Rowledge. [There is a risk in specific acknowledgements, that one may leave somebody out. If this has happened, I hope you will pardon me, and let me know of my omission.] Much neat stuff did not make it into 2.0, and much of what is there remains to be completed. But I think we have a great process going, and I just want to say that if it stays being this much fun, there is no limit to what we can do. Thanks, all, for your part in making Squeak what it is. - Dan
