Hi,
Once again, there's a situation in the Fuel test suite that uncovered an issue. Consider the following script:
Object subclass: #Foo instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Kernel-Classes'.
10 timesRepeat: [(Smalltalk at: #Foo) rename: #Bar. (Smalltalk at: #Bar) rename: #Foo ]
In 5.2-alpha this will open a warning dialog, as at some point one of the class names will be undeclared. Class>>rename: only checks for an entry in the undeclared dictionary without considering that the weak references may not yet have been cleaned up.
I understand that this is not really a realistic real world use-case but it's still annoying for tests. My current workaround is a forced GC after *every* test in the entire suite (I use ClassFactoryForTestCase, so class names may be reused many times over). Luckily, the impact on runtime isn't too bad.
I'd appreciate it if this could be fixed. I'd be even more happy if I could be notified of the fix, so that I can remove the workaround again.
Do you have ideas about where the bug lies?
Cheers, Max
