[BeOS VM] BeOS VM Updated to 2.8
by Colin Sarsfield 04 Jan '01

04 Jan '01

The BeOS VM has been updated to 2.8 and is available for download from: http://www.csarsfield.com/besqueak/ BTW, to whom do I send updated sqConfig.h & sqPlatformSpecific.h files to make sure they make it into the standard image?

[BUG]Cursor/CursorWithMask
by Karl Ramberg 04 Jan '01

04 Jan '01

I've been noticing that some of the cursors show up kind of cut off. This seems to be the result of creating a mask behind them (CursorWithMask) without enlarging the extent to 18@18. Karl

SuperSwiki usage
by Bob Arning 04 Jan '01

04 Jan '01

Hi All, Having had the log running for a week now, I thought some of you might be interested in the distribution of users. You may note the googlebot has been sniffing. Let me know if you start seeing the SuperSwiki in Google search results.

Re: ["BUG"][FIX?]Incorrect Pseudo-Code for#whileTrue:/#whileFalse:?

The method BlockContext>>whileTrue: as written will work IFF it was compiled with the optimization on. In this case the generated bytecodes are: 5 <70> self 6 <C9> send: value 7 <9C> jumpFalse: 13 8 <10> pushTemp: 0 9 <C9> send: value 10 <87> pop 11 <A3 F8> jumpTo: 5 13 <73> pushConstant: nil 14 <7C> returnTop which basically says: 1. Evaluate the receiver block - "self value" at offsets 5,6 2. If the result of step 1 is false, return <nil> from the method - offsets 7,13,14 3. Evaluate the argument block - offsets 8,9,10 4. GOTO step 1 - offset 11 This has led me to wonder whether it would be better if Smalltalk had (horror of horrors) a GOTO. Since the implementation of this method depends on the fact that the optimized bytecodes emit GOTO, perhaps it would be clearer (and more robust, should someone decide to remove the compiler optimization) if it were actually written that way.

Re: Squeak on iPaq draft
by Kevin Fisher 04 Jan '01

04 Jan '01

Ah! Good point! Well, for one I just wanted the maximum hackability factor...I don't have access to a WinCE development environment so I couldn't build Squeak for starters...plus, I've got the flexibility of changing anything I like with the Linux build. Additionally I figure I've got a better chance of stripping Linux down to the bare minimum than I do WinCE..all the more room for Squeak until SqueakNOS can eliminate the need for Linux (or anything else) altogether. Also...well, I just don't like WinCE. :) I use it far too much at work and it gives me a headache. Regardless, the shrinking info will apply to any WinCE users that are living in tight RAM space, I hope. This little experiment is pure hacker's delight right now. :) Sure it's probably easier in some respects under WinCE, but I enjoy the challenge. (as I mentioned right now Linux is just a necessary evil...hopefully someday the iPaq will run pure Squeak). > On Wednesday 03 January 2001 18:24, Kevin Fisher wrote: > > > As promised, I've uploaded my preliminary (very preliminary) draft of how > > to get Squeak (and Linux) on the Compaq iPaq. > > Kevin, > > I forgot why you decided to go to using Linux on the iPaq, rather > than just using a WinCE Squeak port.

Squeak on iPaq draft
by Kevin Fisher 04 Jan '01

04 Jan '01

Hi folks: As promised, I've uploaded my preliminary (very preliminary) draft of how to get Squeak (and Linux) on the Compaq iPaq. My apologies if this seems a bit rough! I'm learning as I go and adding to this as time goes on. Please feel free to add/remove/edit whatever seems at least misguided or blatantly wrong. :) And apologies in advance for any spelling mishaps. See http://minnow.cc.gatech.edu/squeak/1719

[BUG] FFI on Linux?
by John Chludzinski 03 Jan '01

03 Jan '01

Kevin, Using the instructions in /usr/local/doc/squeak2.8/BUILD.UnixSqueak and the source in Squeak-2.8pre3.tar.gz (I just downloaded), I rebuilt the VM on Linux: ../src/unix/configure --enable-FFI=yes make make install I also installed libffi_1.20.tar.gz - BUT I still fail on ANY calls that involve the FFI with a #primitiveFailed message. Any suggestions? Thanks, John PS. I'm using RadHat 6.2.

This way you can record which version your changes were relative to. Example: Suppose you have a change set for 2.7 and want to port it into 2.9. What you would like to know is which of system methods you changed in your change set have changed since then. What you need to do: FileIn this change set into the old system. Run the ChangeVersioner on your change set. Load the new change set file into a change list in the new system. Run 'select conflicts with prior versions'. All methods that have a prior stamp different from the one in your change set will be selected. Michael
