Definitively ephemerons will help to solve that nicely.
I cannot wait for Spur.

We now use a new class for the space-key as key combination. fixed and included in 50045 (https://pharo.fogbugz.com/default.asp?15529)
This way we don't end up with hundreds of obsolete class instances.

But the problem with circular references still exist.
break circular reference for keymappings

I could need some help here, any idea how to work with the key mapping registration without holding (or how to release) strong references?


thanks in advance

Can anyone help me with this. I need a way to break the circular references.

a class is referenced by its compiled method
the compiled method is referenced by the method context
the method context is reference by a block context (the keymapping action)
the block context is referenced by the registration item
the registration item is referenced by the pragma registration builder
the builder is reference by the method context (it is the method argument) and here the
circle closes.

Are there any dictionaries in the above?�� If there are then we can probably use ephemerons to break the circularity.�� This will require Spur and Pharo 5 or ^ (which ever is going to be based on Spur; I can't remember which).�� This may seem like a ways off but it isn't.

Very strange��� using ���explore pointers��� with the old inspector, it shows lots of instances��� I sadly have no
time to now look deeper, but the pointer explorer should be a way to find who holds onto them���
