Hi Stef. I notice that RPackage does not update the extension methods of removed classes. It is easy to reproduce in Pharo 2.0 by doing:

�(RPackageOrganizer �default packageNamed: 'FreeType') allDefinedExtensionMethods � (this fails because FreeType used to have a extension method in TTCFont which was removed)

Or step by step:

1) Create package PackageX.
2) Create package PackageY and ClassY.
3) Create in ClassY a extension method with category *PackageX. If you now browse the instVar "classExtensionSelectors" of PackageX you will see ClassY.
4) Remove ClassY
5) notice that 'classExtensionSelectors' from PackageX still references ClassY. In fact, if you ask its extension methods you will have a KeyNotFound #ClassY in Smalltalk globals ;)

So...I guess this is a bug. �If true, I open an issue.


and to fix the already existing ones we can do:

| extensions |
RPackage allInstances do: [:aPackage |
extensions := (aPackage �instVarNamed: 'classExtensionSelectors').
extensions keysDo: [:aClassName |
(Smalltalk globals includesKey: aClassName) ifFalse: �[extensions removeKey: aClassName].
].�
extensions := (aPackage �instVarNamed: 'metaclassExtensionSelectors').
extensions keysDo: [:aClassName |
(Smalltalk globals includesKey: aClassName) ifFalse: �[extensions removeKey: aClassName].
].�
]


Easier:

2) RPackageOrganizer initialize.
�

Indeed, I saw that later. That only helps to fix the existing ones but it does not solve the problem.�
