Grasping the concept of Classes & Categories
by Daniel Salama 17 Jun '05

17 Jun '05

Hello all, I've been playing with Squeak for some time and have a question. if I wanted to use a Squeak instance to serve different applications (say multiple applications using Seaside), how unique do classes need to be? Sorry for the vague question. Let me be more specific. I have two applications that both need a class Customer. However, one of the application requires that class Customer have a set of attributes and methods very different from the second application who uses the class Customer for a totally different industry. If I create a category for each of the applications, can I have a class Customer for Category A and another class Customer for Category B? In a way, I think I'm going to try to answer the question myself, but would prefer to get clarification or validation from you guys, who are much more experienced than me. The Smalltalk way would be to reuse code as much as possible. Therefore, I should probably carefully design a class Customer so that it may be sub-classed into more specialized classes such as IndustryACustomer and IndustryBCustomer. Is this the Smalltalk mentality? Coming from other environments which don't "encourage" you to work efficiently may be what's confusing me. Thanks, Daniel

[Swiki 1.4] Swiki ask by username:password several times but referencing another swiki in the same server
by German Arduino 17 Jun '05

17 Jun '05

Hi: I've several swikis in the same server, in the form: http://server1:8000/swiki1 http://server1:8000/swiki2 http://server1:8000/swiki3 They all have security enabled with pairs username:password to different roles, as can be defined in the Swiki Administration Tool. I've the problem that when I (or any another user) try to go, by example, to swiki2 with a username:password pair, the swiki remains asking for username:password several times and (in the browser dialog box that ask for the login data) says: "Enter username and password for */swiki1/*" at http://server1:8000 being that I'm trying to go to swiki2. Afther a while (or canceling) the swiki let me go to swiki2 and desired page, but when I try to go back (yet inside swiki2) again the multiple asking by username:password naming swiki1. The same is true with the others swikis and runnig the ComSwiki in Linux or Windows. Any help will be appreciated. Best Regards. gsa.

pending mac os-x browser plugin 3.8.8b3
by John M McIntosh 16 Jun '05

16 Jun '05

I've migrated the netscape plugin NPSqueak.bundle from 3.7.5b1 to 3.8.8b3. This change covers a lot of ground, however it should fix: a) crashes from time to time in draw logic b) faster updating and more CPU time to Squeak when it is busy. c) a million other things since 3.7.5b1 to 3.8.8b3 changes cover lots, see below. Find a beta version at http://homepage.mac.com/johnmci/FileSharing.html experimental:BrowserPlugin directory NPSqueak.bundle.zip You should unzip the plugin and replace the NPSqueak.bundle found in /Application/SqueakLand/Squeak/Internet/ with the new version, then restart your browser and run some tests. 3.8.8b3 sqMacNSPlugin.c Alter screen updates to 60 per seconds, wait on each event for 15 milliseconds to give Squeak time to update screen. 3.8.8b2 Revisions to the 32/64bit memory access to improve VM performance sqMacEncoding.c, Fix bug reported by Stephan B. Wessels swessels(a)cox.net, crash on Tiger if squeak.image is in resource folder sqMacJoystickAndTablet.c More rewrites by Bert. sqPlatformSpecific.h Add undefs for dispatchFunctionPointer, dispatchFunctionPointerOnin sqMacUIAppleEvents.c Fix issue with window title not showing long image name on drag & drop image sqMacMain.c Fix issue with window title not showing long image name on image selection from dialog prompt. sqMacUnixCommandLineInterface.c New, enable command line functions and environment variables. -help print this help message, then exit -memory <size>[mk] use fixed heap size (added to image size) -pathenc <enc> set encoding for pathnames (default: UTF-8) or as environment variables SQUEAK_IMAGE, SQUEAK_MEMORY, SQUEAK_PATHENC 3.8.8b1 Not released to general public sqMacAsyncFilePrims.c (void*) for ioLoadFunction sqMacDragDrop.c (void*) for ioLoadFunction sqMacHostWindow.c (void*) for ioLoadFunction sqMacJoystickAndTablet.c minor changes sqMacSecurity.c (void*) for ioLoadFunction sqUnixSoundMacOSXJMM.c add static to var to avoid compiler warning sqMacExternalPrims.c (void*) for various module interfacing sqMacWindows.c (void*) for ioLoadFunction 3.8.7b7 Revised and altered os-x joystick support based on changes by Bert Move towards 32/64bit VM logic by using latest VM Maker sqMacExternalPrims.c (void *) usage sqMacFileLogic.c (void *) usage 3.8.7b6 Added Dominique Dutoit hitoro(a)easynet.be changes for os-x joystick support. 3.8.7b5 Fix logic to allow you to start VM from command line, changed sqMacFileLogic.c makeHFSFromPosixPath added to convert posix cmd line path names to HFS sqMacMain.c add logic to call cmd line parser sqMacUnixCommandLineInterface.c new file logic to parse cmd line sqMacUnixCommandLineInterface.h sqMacWindow.c minor changes to correct compiler errors 3.8.7b4/b3 Limited release for testing 3.8.7b2 sqUIEvents.c changed keyUp/keyDown to supply mac virtual keycode versus unicode, added new parm to keyChar to supply UTF-32 Unicode. As per Andreas request for Tweak. 3.8.7b1 sqUIEvents.c changed keyUp/keyDown logic to match Windows pattern, key repeat becomes keyDown/keyDown/keyUp 3.8.6b6 sqMacMIDI.c add #def so I can compile under code warrior os-9 again sqMacEncoding.c, sqMacEncoding.h Minor changes so I can compile user code warrior os-9 again sqMacUnixInterfaceSound.c Fix problem with empty buffer being full of junk under certain conditions, that causes a sharp sound bite. 3.8.6b5 Change to JMM & AR GC instrumentation patch, collect a few less statistics. Also change carbon VM to use Unix/ Quartz sound driver which interfaces to Core Audio stuff. 3.8.6b4 Ensure VMMaker 3.8b2 - the VM code classes and tools for building a working vm for Squeak version > 3.8-6461. is incorporated. Add Andreas's GC improvement changes for * primitiveIsYoung: This answers the question whether an object currently lives in young or in old space. * primitiveIsRoot: Answers the question whether any given object is currently a root for young space. * primitiveRootTable: Answers a snapshot of the current root table. Useful to examine the roots table if the analysis requires complex other operations during which the root table might be modified itself. Note that since this primitive can cause GC there is a small chance that it will give an inaccurate answer. * primitiveRootTableAt: Answers a single element of the root table (by one-based index). This primitive can be used to quickly scan the root table for certain objects. * primitiveSetGCSemaphore: Indicates a semaphore (index) to be signaled whenever a garbage collection occurs. I can see at least two uses uses for the GC semaphore: running cleanup actions (for example after full GCs occured) and dynamic parameter tuning for the GC algorithm itself. Add John's changes for Smalltalk setGCBiasToGrowGCLimit: 16*1024*1024. "Set growth limit before full GC to 16MB" Smalltalk setGCBiasToGrow: 1. Set bias to grow upto GCLimit, this can avoid a problem where we attempt to avoid growing but results in thousands of incremental GC events as we approach a knee in a curve of space used versus the growth/compaction decision. 3.8.6b3 Add in logic for become: to fix issues with changes to become: logic. 3.8.6b2 sqMacWindow.c reduce number of lock/unlock pixel events and flush no more than 91 fps, with flush check every 1/50 or 1/60 and 1/5 of a second. this shaves another 50% off making drawing pixels 1.3% of the time originally taken. 3.8.6b1 sqMacWindow.c, sqUIEvents.c, changed logic to flush screen every 125 fps, this makes pixel level drawing complete in 2% of the time originally taken. 3.8.5b1 Fix issue with gnuify. The offical gnu header file used a different #ifdef for the foo register than an altered gnu header file I was using for many years. This resulted in slower performance, which is fixed in 3.8.5 3.8.4b3 Support for GC statistical data and change to how memory is allocated and tenured. Additional statistical information from the GC routines Additional primitives to set GC semaphore, and to force a tenure Change to make forward logic to look for "foo become: foo" and cause a prim failure. Earlier version of 3.8.4 where distributed to Ffenstri testers. sqMacHostWindow Change calls to move and size window to use GUILocker callbacks to avoid VM crash. sqMacWIndow.c Alter 1/2/4 bit support to pass in bit size of target window, then copy is more efficient. 3.8.3b3 Support for Host menus and windows. Also added back 1bit (B/W) and 2bit & 4bit color as requested by Dan Ingalls for os-x Earlier versions of 3.8.0/1/2/3 were distributed to the TK4 team, not the public. sq.h Added events, EventTypeMenu, EventTypeWindow to handle menu and window events generated by the Host OS and placed on the Squeak Event Queue to be read by EventSensor sqGnu.h Switch to the current file used by Ian for Unix, versus older modified copy. sqMacExternalPrims.c Cleanup of warning message sqMacImageIO.c When you set the image name, we set the title on window 1. sqMacMain.c Do not create the main window until we actually use it. sqMacNSPlugin.c Always refer to window 1, not sure what it means to have other windows in the plugin yet... sqMacUIEvents.c OS-9 Pass cmd-key menu activity up Pass update event bounding box window events up Pass window activate events up Pass menu interaction activity up Pass window events, resize,zoom,close,move,inconize up OS-X Same as above getUIToLock needs to ReleaseEvent on the passed in event for GC reasons sqMacUIMenuBar.c disable edit menu at start, if later we find it enabled, don't touch, otherwise handle os-9 DA issues. sqmacWindow.c sqShowWindow now gets a windowIndex parm. ioShowDisplayOnWindow is added, with logic to build main window at first draw time, also fix some boundary checks, and provide support (again) for 1/2/4 bit color under os-x ioHasDisplayDepth() will return true for 1/2/4/8/16/32 bit color 3.7.5b3 OpenGL fix by Bert. Open Squeak3D.log in the currently directory, not the root volume, also ensured this works in os9. sqMacNSPlugin.c Alter memory check at startup to ensure we see all 512MB, not a default of 30MB sqMacUIMenuBar.c Don't hide menubar if squeak screen is full screen on secondary screen. sqMacWindow.c When you open in full screen mode, then revert, ensure the screen is resized rationally. Also remember screen size and location when going into full screen so revert is sane. -- ======================================================================== === John M.

File team report
by Bruce O'Neel 16 Jun '05

16 Jun '05

... ie me. We've updated the two ftp sites to 3.8 and we have a 3.8 basic image with the french translation. We could use an updated 3.8 full image. Other than that, not much to report. I put a version of 3.1beta on the ftp sites as well just because someone needed it. Maybe I was a bit too aggressive in deleting the alphas and betas :-( cheers bruce -- "We didn't just track down that bug, we left evidence of its extermination as a warning to other bugs" - Dan Lyke - flutterby Bruce O'Neel phone: +41 22 379 21 57 INTEGRAL Science Data Centre +41 22 379 21 00 (switchb.)

Janitors Task 2 Sub-team forming soon
by Ken Causey 16 Jun '05

16 Jun '05

Finally I am preparing to start Task 2 of the Janitors team which is a short term project to move all remaining open issues in BFAV to the Mantis server. At this point I've posted a draft of the plan at http://discuss.squeakfoundation.org/cgi-bin/ezmlm-cgi?8:mss:208:200506:kljf… and http://discuss.squeakfoundation.org/cgi-bin/ezmlm-cgi?8:mss:209:200506:eceg… and am looking for feedback from anyone that is interested in helping with this project on whether or not this document is readable and understandable and seems like a reasonable way to do the job. This process is a derivative of that being used for Task 1 so you may also be interested in reading about the process we are following there at http://discuss.squeakfoundation.org/cgi-bin/ezmlm-cgi?8:mss:49:ndnfioklioln… If you think you might be interested in helping out with this project please read over these documents (at least the ones related to Task 2 anyway) and join the Janitors mailing list by sending a blank email to janitors-subscribe(a)discuss.squeakfoundation.org If you would please post any comments or questions to the Janitors mailing list. Thanks, Ken

MultiByteStream
by stéphane ducasse 16 Jun '05

16 Jun '05

Hi I did the following |stream | stream := (MultiByteFileStream fileNamed: 'BD4TabsDelimited.txt'). stream converter: MacRomanTextConverter new.self assert: (stream upTo: Character cr) = ' Achille Talon Greg Pas de pitié pour Achille talon 13 1976 Dargaud "sur la couverture ""une histoire du journal tintin""" ' Now I'm trying to use MultiByteBinaryOrTextStream as follow |stream | stream := MultiByteBinaryOrTextStream on: self completeWithTabbingLinesWithAccents encoding: 'mac-roman'. self assert: (stream upTo: Character cr) = ' ' Does anybody know why I get '' and not ' Achille Talon Greg Pas de pitié pour Achille talon 13 1976 Dargaud "sur la couverture ""une histoire du journal tintin""" ' It seems that the stream once instantiated is at the end. (readLimit is 0 when the instance is created) How can I say to the stream to be at the start. I tried reset, resetAtStart without success when in an inspector I copy the writeLimit to the readLimit then upTo: works perfectly. Is it a bug? Stef

Final 3.8 and translations ?
by Hilaire Fernandes 16 Jun '05

16 Jun '05

Hello, www.squeak.org is still pointing to stable version 3.8 of the image. Is 3.8 image officaly out, released? Does the 3.8 image will finally include locale translation or do we need forking for version including locale languages as it has been done for previous versions? - ie at http://squeak.ofset.org and here (http://p7app.geneve.ch:8090/squeak/39) a description to install French local which for sure Squeak newbie will not do and then will drop Squeak for lack of local language support - I am willing to help to get locale language included by default in the official image but how it is not clear to me.
