Bug 41759

GemBuilder for Smalltalk/VA

5.4.6, 5.4.5, 5.4.4, 5.4.3, 5.4.2, 5.4.1, 5.4, 5.3.2, 5.3.1, 5.3, 5.2.7, 5.2.6, 5.2.5, 5.2.4, 5.2.3, 5.2.2, 5.2.1, 5.2, 5.1.x


GemBuilder filein class creation won't version subclasses or copy methods

If a GemStone Smalltalk filein from GemBuilder does a doIt command that
creates a new version of an existing GemStone class, subclasses of that
class are not versioned along with it.  For example, if I have class A
with subclass B, and a filein redefines A to add an instance variable,
then class B will still inherit from the old version of A, without the
new instance variable.

Also, a filein that simply redefines the class (to do something like add
an instance variable) will not try to copy the methods from the old class
into the new class.

These are features that you get if you use a browser to do similar operations.
These features might not be as important in a filein, since fileins are
usually (but not always) complete descriptions of a class or collection
of classes.


Use a GemBuilder browser to make changes to a GemStone class definition.
If you must use another interface, you should:

- file out that class, and all classes that inherit from it
- make the modification to the filed out file
- file in the the classes in superclass order - that is,
   start with the class that was modified, and then file in
   its subclasses, then their subclasses, and so on
