Back to WM_UNICHAR?
by Chris Petsos 15 Jun '07

15 Jun '07

Remember at start that you 've been telling me to acquire unicode chars by handling the WM_UNICHAR message? Well...i didn't and now i am having the first problems... First...keyboard shortcuts do not work of course when i have the keyboard turned to my locale. The charCode member of the event buffer takes values above 128... We can interpret it back to MacRoman values inside the image but then the so called "unicode" environment will be polluted with locale specific code. Also, each environment can provide interpreters for itself without polluting the base UnicodeEnvironment class but still i don't know. Another, smaller, problem is that the mouse wheel does not work...and i don't know what else can come up in the future... Do you think it would be wise to try once again handling WM_UNICHAR and leave everything else unchanged? Documentation and reports on this message are really vague and controversial... some did it, some didn't ...i don't know! Any suggestions??? Christos.

Something along the lines of self cCode: 'fwrite("asdf", 4, 1, self sendProfile)'. of course won't work, and then I'd still have to somehow mix my variables into the C code. That's where it starts getting nasty again. Any suggestions? Thanks, André

Hi Bert, I'm trying to write a logging facility for send (sample work for Prof. Hirschfeld, actually): Each time a message is sent, the target class, message and a couple of other properties should be logged. That means I have to open a file upon initialization and write the file at each send. There's no other way than to do that in the Interpreter, as far as I can see. André

Howto invoke plugin primitive from Interpreter?
by André Wendt 14 Jun '07

14 Jun '07

Hi, I'm trying to invoke the primitiveFileOpen primitive from the FilePlugin from within the Interpreter: <primitive: 'primitiveFileOpen' module: 'FilePlugin'> obviously does not work: It doesn't get translated to C. How do I invoke a primitive of an (internal/external) plugin from within the Interpreter class? Thanks, André

Howto invoke plugin primitive in Interpreter?
by André Wendt 14 Jun '07

14 Jun '07

Hi, I'm trying to invoke the primitiveFileOpen primitive from the FilePlugin from within the Interpreter. <primitive: 'primitiveFileOpen' module: 'FilePlugin'> obviously does not work: it doesn't get translated to C. How else should I invoke primitives of (internal/external) plugins from within the Interpreter class? Thanks, André

Hi folks, Is not posible to find all the buggy casts (between unsigned and signed ints) using this compiler flags? Anyone did try it? Cheers, -- Diego

32 bit clean, and object size?
by John M McIntosh 11 Jun '07

11 Jun '07

When I was altering the size of freeblock to return usqInt, it occurred to me. Gee how big can a smalltalk object be? 1GB 2GB 3GB 0xC2ABCDEF98765432 bytes. Oh and is it signed or unsigned, does it matter? Alas I'm too squeaked out to look. However someone might what to look and decide what those answers are... Oh and actually is the value we stick in freeblock size actually able to represent the value say if you had 4GB of memory and say only 4MB in use? I mention all this because when VisualWorks was transitioning from 512MB to much larger, in many places they and their clients discovered that 512MB being a SmallInteger was used, say like for the free space calculation, unfortunately for the 5.x series of VMs, passing a LargeInteger (says 800MB) back to the VM GC interface would cause the VM GC logic to crash. So as we pass 32bit values about I wonder? -- ======================================================================== === John M.

SVN updates with David T Lewis' changes to sqMemoryAccess.h
by John M McIntosh 10 Jun '07

10 Jun '07

I've updated SVN with changes that David made to sqMemoryAccess.h for 32/64bit clean work. I added his change sets, plus a correction to the Mac OS tree until someone can validate on windows and linux, and 64bit linux, then of course someone could pay Tim to integrate them into VMMaker. I've also checked in the 3.8.18b1 macintosh VM changes which seems to work. A 3.8.18b1 VM will follow shortly. As of this evening I tested David's changes plus my changes on an image that ran macrobenchmarks below, crossing and above the 2GB boundary, and again when the image is allocated at the 3GB boundary. Although this shows the VM does not crash in those two situations it does not test 64 solutions, nor did it prove that any plugins play nice. -- ======================================================================== === John M.

Unix keyboard events...
by Chris Petsos 09 Jun '07

09 Jun '07

Hello everybody... I am trying to see what we'll do with greek support in the unix VM. When i turn the keyboard layout to greek, the only charCodes i can see in squeak are 235 and 236 for all keys... Anyone knows why this is happening? I've tried to experiment with the various command line parameters but i don't seem to be getting somewhere... Really? How have you coped with your locale-specific input in the unix VM? Christos.
