[BUG]UndefinedObject(Object)>>doesNotUnderstand: #do:

I am getting this when trying to open a SqueakMap Package Loader in a
fresh 3.7-5989-Full image. I am sure that I could do this before, has
anything changed on the SqueakMap side?

I am on x86 Linux (Ubuntu) with the 3.6-3 VM from Ian Piumarta's site.

Thanks in advance for any help,

Barry

Sorry to reply to my own message but I just tried the same thing under
Windows XP and everything worked OK. Not sure what is happening.

New Squeak VM Documentation

Hi,

Here is the first draft documentation I have created on the Squeak VM :-

        http://angray.members.beeb.net/Squeak/TheSqueakVM.html

The thing is hyperlinked, although for neatness hyperlinks are not colored 
or underlined.

Any comments, suggestions or corrections are welcome.

Happy new year,

Aaron

Balloon canvas not scaling

There does not appear to be an implementation of 
Canvas>>transformBy:clippingTo:during:smoothing: (used by 
TransformMorph for drawing submorphs) for BalloonCanvas.  This means if 
falls back on FormCanvas which simply scales the bit map.  
BalloonCanvas does appear to support a transform however.  Was this an 
oversight or intentional?  I will attempt to play with it and get an 
implementation that works, but any help or pointers would be welcome.

I am trying to do zooming on morphs containing various balloon drawn 
shapes.

My first attempt has not worked out well.  I added the following 2 
methods into TransformationMorph which is the owner of the morph I am 
testing with.  I would do the real work in a subclass, but just added 
them for testing purposes.

fullDrawOn: aCanvas
	| myCanvas |
	aCanvas isBalloonCanvas ifTrue:[^super fullDrawOn: aCanvas].
	myCanvas _ aCanvas asBalloonCanvas.
	myCanvas deferred: true.
	super fullDrawOn: myCanvas.
	myCanvas flush.

transformBy: aDisplayTransform clippingTo: aClipRect during: aBlock

Re: [BUG]UndefinedObject(Object)>>doesNotUnderstand: #do:

This looks very much like the very irritating problem where the object
memroy range crosses over the 2Gb level and some important code is
treating oops as signed integer. Do a comparison when that happens and
the code fails, the relevant primitive fails and the segment loading
fails.

We will eventually fix this. Just don't hold your breath since dark
blue is a very unnattractive colour for a human face. Even if you still
claim Boudica as your Queen.

Which font for publishing eToys project...

Which font should I be using in my published eToys project so that the
plugin will not throw the following error: LinedTTCFont is Missing?

Thanks,
Mark

Re: Balloon canvas not scaling

I have this working, but the results are not all that good for 
ellipses.  Lines look good, but ellipses are distorted.  This may have 
to do with the brush used, but It looks odd even for that.  The 
resulting shape is pin-cushiony.  A circle is drawn with spikes on the 
inside of the shape, and rounded areas on the outside.  I tried a 
screen shot but it was too large for the list filter.

This looks like the 2Gb problem. I was getting that when I used

 -mmap 512M

but not when I used the default (which on my system would be 1024M).

What command-line arguments are you using?

How much virtual memory is available?
