1:56 p.m.
Hello,
Last week I had a error due to a strange behaviour: I had an instance
variable and an accessor to this instance variable. The instance variable is
instanciated at the initialization of the class. When the error occure, the
instance variable is not nil (when inspecting it from the debugger ). But,
when evaluating the accessor, it return nil.
This occure in the pharo 1.0 dev image. I test it this morning on a clean
image and on a click image with moose. It seems that the bug is specific to
moose. If you want to reproduce it:
Download the last version of Merlin from
www.squeaksource.com/DelaunayTmpStuffs.
run the method MerlinExamples class >> parametrizedMorphDropLists. it should
work correctly.
Now restart, load moose (load ConfigurationOfMoose, and evaluate
'ConfigurationOfMoose loadDefault') and then load Merlin from
'DelaunayTmpStuffs'.
It should raise an error and you should be able to see this strange
behaviour. From the debugger, evaluate 'self dropList' in MorphDropListPart.
After showing this bug to Marcus, it seems that something is not weel
compiled at one point: browse the method 'dropList' in dropListPart. Now,
click on 'view' and 'byte code'. The offset indicated is 10 whereas it
should be 15
11:29 p.m.
That is too low level for me :)

We should check the Moose overrides?
is there somewhere a method adding behavior to behavior and friends?
I did not get the time to have a look.

After playing a bit with that, it seems that it is not moose specific. I
have maybe an idea about the origin of the Problem:
I have a package, Merlin, which is usually saved in is own repository,
www.squeaksource.com/Merlin.
I had to make some changes on Merlin, and during all this time, I saved all
the 'dummy versions' of Merlin in another repository:
www.squeaksource.com/DelaunayTmpStuffs.
Now, if I compare the latest version from those two repositories:
in www.squeaksource.com/Merlin, BEFORE CHANGES , the offset of the instance
variable causing the problem is 10.
in www.squeaksource.com/DelaunayTmpStuffs, AT THE END OF CHANGES , the
offset of the instance variable causing the problem is 15.
The problem will only happen when merging those two versions. If you load
the version directly from DelaunayTmpStuffs, all will be ok.
Then, I don't know how the information about the instance variable offsets
is propagated along the different versions of a package. But it seems that
when merging, the information (telling that the offset of the variable has
changed) has been lost in all the version of DelaunayTmpStuffs

So it looks like methods which are not changed by a merge and access instance variables do
not get recompiled when the class definition changes? That is strange that such a bug
still exists in Monticello. Try to do a very simple test case with a dummy package before
posting the bug on Pharo, I would like to check that.
