Kernel.image update for 7052 and my vision of the next development
by Pavel Krivanek 02 Aug '06

02 Aug '06

Hi all, There's the new update for my kernel image for Squeak 3.9 (without next packages) http://www.comtalk.net/Squeak/uploads/20/bootstrap7052.zip If you run "Bootstrap new browseOverrides", you can see list of all changed methods. This image overrides only 122 methods so I hope that it will be quite easy to begin with refactoring of full Squeak (3.10) to minimize the amount of necessary overrides and publish it on Mantis. We should use some special mark (e.g. [KERNELIMAGE]) for such patches or create new project. The most important refactorings: ======================= - ChangesOrganizer that picks general changes manipulations from the ChangeSorter tool and makes that operations independent on it. Andreas already published similar patch some time ago but it was not accepted. This invokes overriding of very small set of methods in the kernel but the impact on the full image will be much bigger (but in most cases it will be only renaming from ChangeSorter to ChangesOrganizer) XxxChangeSetCategory >> reconstituteList XxxChangeSetCategory >> changeSetList XxxChangeSetCategory >> includesChangeSet: XxxChangeSetCategoryWithParameters >> reconstituteList XxxChangeSetCategoryWithParameters >> includesChangeSet: XxxFileStream >> fileIntoNewChangeSet - extend UIManager to make the kernel independent on UI. It's about 30 methods it means to take the current source and create the corresponding code in the MorphicUIManager or MVCUIManager XxxAbort >> defaultAction XxxBlockCannotReturn >> defaultAction XxxChangeSet class >> promptForDefaultChangeSetDirectoryIfNecessary XxxContextPart >> doPrimitive:method:receiver:args: XxxDisplayScreen >> restoreAfter: XxxDisplayScreen >> restore XxxDisplayScreen >> newDepthNoRestore: XxxDisplayScreen class >> checkForNewScreenSize XxxDisplayText >> composeForm XxxError >> defaultAction XxxEventSensor >> startUp XxxFileDirectory >> rename:toBe: XxxFileDoesNotExistException >> defaultAction XxxFileExistsException >> defaultAction XxxHalt >> defaultAction XxxMethodContext >> cannotReturn: XxxObject >> primitiveError: XxxProcess >> debug:title:full: XxxProgressInitiationException >> defaultAction XxxSmalltalkImage >> snapshot:andQuit:embedded: XxxStandardFileStream class >> fileExistsUserHandling: XxxStrikeFont class >> fromUser: XxxSyntaxErrorNotification >> defaultAction XxxSystemDictionary >> lowSpaceWatcher XxxSystemDictionary >> handleUserInterrupt XxxTextStyle class >> replaceFontsIn:with: XxxUnhandledError >> defaultAction XxxUtilities class >> informUserDuring: XxxUtilities class >> informUser:during: XxxWarning >> defaultAction So if anybody wants to help with Squeak modularization, this is the right sand to play. The next step is to discuss the rest of overrides (maybe we should create Mantis record for each). Then we should create clean package The Rest of Squeak. The phase of its loading is simple because that means only to authomatically create the set of new classes, methods and very small set of overrides. We will need small basic image without all packages that can be safely removed (FFI etc.) for that. The biggest problem is to initialize fully working Morphic world (but we are already able to do that partly). I expect that then we will be able to create script that will shrink the image to the kernel without self-bootstrapping process. So as the result we may have "our" (not only "my") kernel image. The final basic image will be almost the same as the current image so we will burn no important bridges but we will have well described process of Morphic initialization and (still little messy but usable) kernel (maybe not official for end-users but important part of Squeak development and modularization). I would like to see it as the main goal for Squeak 3.10. I expect that it may take about two or three months. Your comments? Cheers, -- Pavel

[SqNOS] New release: RTL8139 support, TCP/IP "working", native improvements
by Gerardo Richarte 02 Aug '06

02 Aug '06

Download: http://sourceforge.net/project/showfiles.php?group_id=3891&package_id=3865 swiki: http://minnow.cc.gatech.edu/squeak/1762 This release includes two NetworkingDevices: LancePCIDevice and Realtek8139PCIDevice, the former implementing support, at least, for VMWare virtual cards, and the latter for a very common real network card. We have partially integrated NetSqueak (http://www.squeaksource.com/Net.html), which gives SqueakNOS support for most of the TCP/IP protocol suite, including basic, but working, TCP. The native part has changed a little bit too, specially a bug fix to allow bigger images to be booted (27MB was the old limit, now phisical memory should be it). Also the timer interrupt frequency is increased to 2KHz and ioRelinquishProcessor... effectively halts ('hlt') the processor. This decreases the power consumption, and introduced a few interactivity glitches that we should solve. gera

deep problems (Monticello & class methods)
by Ramiro Diaz Trepat 01 Aug '06

01 Aug '06

Hello, A very strage thing is happening on my image. I have a class, called MagmaDSProxy. Everytime I try to browse its class methods categories I get an error: MessageNotUnderstood: MagmaDSProxy: hasBindigThatBeginsWith: Besides this, Monticello started to be unable to save my project. I really don't know what is happening. I wish I could get my code out with Monticello to start again from a fresh image. I will appreciate any advice. Thank you. r.

Suggestions for C++ or DLL code
by Ron Teitelbaum 01 Aug '06

01 Aug '06

Hello all, I'm currently working on a TLS / SSL implementation and on windows I am planning to support the Certificate Store that is built in. This requires me to use the CryptoAPI dlls. The code is complex and it uses a number of header files and many steps. I built some C++ code that does what I'm looking for so now I would like to incorporate this into Squeak. I'd assumed that FFI was like DDL/C connect in VW but that's not what I'm seeing. So my question is: What is the best way to get this working? Should I hack away at FFI and support the api directly, and is that even possible? Should I create DLL's to call and use them with FFI, or should I compile some sort of plugins? My preference would be to call the api directly without having to create dll's, duplicating my C++ code in Smalltalk if possible. Some direction and comparisons of different options would be very helpful. Thank you for your help! Ron Teitelbaum

Hi, 1/ I'm playing with SIXX and I call upon your memory about troubles with it. I've already seen some troubles in mailing list archives... 2/ Have you big (critic) applications using sixx? 3/ The SiXX description says: > Advanced users can implement custom serialization/deserialization > format by overriding only a few hook methods Maybe someone have tried to do something like this? Thanks FLO

Jun port?
by David Faught 01 Aug '06

01 Aug '06

Has anyone looked at porting Jun to Squeak or Croquet? I'm looking particularly at some of the modeling tools, but it looks like a very rich set of tools. http://www.sra.co.jp/people/aoki/Jun/Main_e.htm

Icons in Unix
by Keith Hodges 01 Aug '06

01 Aug '06

I know that when developing a server one should not be interested in such trivialities, but, does squeak have any icons in the KDE/Linux world? At the moment on my installation squeak is a X11 logo which just feels so wrong. Keith ___________________________________________________________ Try the all-new Yahoo! Mail.

Hello :) - i think a bug
by Gary McGovern 01 Aug '06

01 Aug '06

Hi :) I recognise a lot of the same names from few years ago. I haven't used Squeak for a couple of years, but at the weekend I got the 3.8-6665 for windows. It's hard to learn other stuff and then use Squeak on top of that. So I think I've fogotten Smalltalk. Straight away I had a problem. I made the beginnings of an Etoy, closed the project and then renamed the project with edit label menu item............that project will no longer open??? The system just hangs and I have to close Squeak and restart it but can click on that project otherwise the same The project was not so important because I just made another of the the same etoy, but better. Thanks Gary ps. Now I appreciate the Squeak collection classes more now. Smalltalk was my intro to them. I've since started to use the Java and C++ collections, and they are shocking, I am horrified by them. At least the C++ is more mature, but that is all I can say. I read some of Alan and Ted's recent work. Not many people shock me with brilliance........ --------------------------------- All New Yahoo! Mail Tired of Vi@gr@! come-ons?
