New Revision: 42261
Modified:
python/trunk/Tools/bgen/bgen/bgenObjectDefinition.py
Log:
Fixed an oversight and a misunderstanding of PEP253:
- Call tp_dealloc on the static baseclass, not dynamic (which leads to
infinite loops with more than one baseclass)
- Call tp_new and tp_init on baseclasses (overridable)
-This line, and those below, will be ignored--
