Formalizing class dynamic software updating


This approach is appealing because it is general-purpose: any application can made dynamically updatable without requiring special support.

Whereas there are some studies on the correctness of dynamic updating, they focus on how to deploy updates at the code level, e.g., if procedures refer to the data of correct types.

However, little attention has been paid to the correctness of the dynamic updating at the behavior level, e.g., if systems after being updated behave as expected, and if unexpected behaviors can never occur.

Our methodology is general in that: (1) it can be applied to three updating models that are mainly used in current DSU systems; and (2) it is not restricted to dynamic updates for certain programming models.

Dynamic software updating (DSU) enables running programs to be updated with new code and data without interrupting their execution.

As a first step in this direction, we introduce a small update calculus with a…designed for quick setup and changeover, state-of-the-art digital control and drive systems, and user-friendly step-by-step programming makes the universal cylindrical grinder a flexible solution to a wide variety of internal and external grinding applications.Dynamic Software Updating (DSU) is a technique of updating running software systems on-the-fly.Knowledge Inference for Optimizing Secure Multi-party Computation.
