Found Bug But Not Sure How to Proceed To Fix

That bug tracker is pretty much dead, since all ongoing development moved to squeak.org.

The plan was to make a new Etoys release based on the latest Squeak source base, but we have not have enough developer time to make that actually happen.

Hi,

I found a bug tracker on the squeakland site:
http://tracker.squeakland.org/secure/Dashboard.jspa

I think, you can describe the problem there as an issue and hand in the fix.
They may also know how to guide you further if the code base is somewhere else.
If you have problems there (login, no response), I guess, this mailing list is one place to ask for help.

Best,

I'm quite certain this bug is the one that causes bad redrawing, especially when showing a cursor move when 'indicate cursor' is activated in a playfield.

If I correct this bug inside of a project, will it load into an image where it has not been fixed and be fixed?

I haven't actually fixed the bug yet, but didn't want to waste time on it if the fix will not travel with the project.  

Thanks in advance for any input.

I tried to recreate your example and could not. How did you create the two morphs in your example? Are you certain the read/gray morph does not have some transparent pixels along the top and left?

Hi, it only appears when scaling a morph.  Here is example...it is my belief (how does one step through code with debugger if there's no bug happening?);

Whatever code is common that scales morphs is being offset incorrectly. The first image shows the 'garbage' left behind by playfield indicator if that option is set.  It seems it was only tested in 'holders' and thus likely not picked up during 'intended' use.  

Next, two pictures show scaling as where the misalignment starts.  This might be why you could not recreate bug; resizing rectangle changes rectangle morph extent, whereas scaling is a differnet piece of code and therefore different outcome.

Image included.  This works with *anything* scaled.

You will also notice if you rotate any shape, it becomes a bit map.  Scale it and you will see that problem re-occur even with built-in objects.  Could it be the masking offset, too?  that causes this?  I'm still investigating, but I'm not sure how to step through 'already working' things specifically related to what I'm trying to look at.

Actually to add a little more insight if possible, you can create bug with the following actions:

make a new playfield

make 2 new rectangles and place them into the playfield.

Rotate one of them 90 degrees.

Turn gridding on in the playfield.

The rotated and unscaled rectangle will not align with the non-rotated one with gridding.  Something about making a bitmap copy is offsetting the values, my guess is there's a rounding problem that is popping up on these objects, thus scale and rotation get offset for some reason, and specifically changes the origin by 1@-1 somewhere...it causes graphical glitches leaving 'garbage' with playfield indicators when the object that has the indicator is moved and also shows up with rotated ellipses.  What is the common thread through them all?  What method are they all accessing?

Does anything bad happen if the "expandBy: 1" is removed? I tried removing it
in my Squeak trunk image, and "CompassDialMorph new openInWorld" (which is one
user of TransformationMorph) seems to work nicely.

And if the "expandBy: 1" is removed in an Etoys image, does anything bad happen?
Does it fix the issue that Jeremy is seeing?

This would be an easy thing to fix in Squeak trunk, which hopefully will become
part of future Etoys releases, knock wood.

So far, with a little testing, everything lines up much better with .1 instead of removing it.  removing that offset still sees to make it offset, but .1 lines everything up visually more...still not perfect, but much less flagrant.  It still has a clipping glitch (you can see it with a rectangle when rotating: the border gets clipped off) but it does visually appear more 'solid' and expected when aligning rectangular shapes together.

I'm going to keep experimenting to find something that keeps the rotated bitmap in tact while still aligning properly.  I feel like I probably glanced at a method that needs an edit over and over but haven't realized which one it is yet. I still need to look into the cursor not being properly redrawn as well.  I might be stretching or trying to make a connection that isn't there, but something 'feels' related to this and the cursor, like some common reference point is being shifted so that the cursor's area for drawing doesn't reach the left and bottom edges just like the origin doesn't reach the left and bottom edges correctly for the this rotation issue.

Does anything bad happen if the "expandBy: 1" is removed? I tried removing it
in my Squeak trunk image, and "CompassDialMorph new openInWorld" (which is one
user of TransformationMorph) seems to work nicely.

And if the "expandBy: 1" is removed in an Etoys image, does anything bad happen?
Does it fix the issue that Jeremy is seeing?

This would be an easy thing to fix in Squeak trunk, which hopefully will become
part of future Etoys releases, knock wood.

And I can back that up, now...

PasteUpMorph cursor  _also_ uses the expandBy: method and has redrawing issues.

Somehow I think morphs are either giving wrong information to the the expandBy: method or expandBy: is doing it's own calculations incorrectly....

Change the expandBy: to any number and the cursor square will change (use a larger number, btw) and it will still not erase correctly.  It has a 2 pixel offset, the same as the thickness of the cursor.
