…to facilitate reproduction of production bugs in small tests through steering decisions at two key points in the MSA pass flow, before and after AllocateSegment() call: 1) debugging_allocation_request_modifier_fn(): allows modification of AllocationRequest before AllocateSegment(AllocationRequest) calls. 2) debugging_allocation_result_modifier_fn(): enables enforcing arbitrary failures on allocation requests, modifying the output of AllocateSegment(AllocationRequest) calls.
