Readme for strict-stm-

[back to package description]

Strict Software Transaction Memory

The strict-stm package provides a strict interface to software transaction memory. It builds on top of io-classes and thus it provides the interface for both stm as well as io-sim.

Novel testing / space-leak elimination approach

The strict interface provides a novel way of testing/eliminating space-leaks which might lurk in stm shared mutable variables. Together with the nothunks library it was successfully used to eliminate and keep a large system (cardano-node) space leak free.
