[PATCH 02/30] Make the allocation and grow code optional.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



* storage/partitioning.py (doPartitioning):  By default we run both the
grow code and the allocation code.  We could, If we were very careful,
avoid running either the allocation or the grow parts.
