Dynamic software updating c Dateinggranny
However, both of those systems require target programs to pass a static analysis that may be over-conservative.
They also perform significant source-to-source compilation of the original program, which adds overhead and can inhibit compiler optimizations.
Researchers compare DSU-capable variants of programs to the original program to assess safety and performance overhead.
The location in a program where a dynamic update occurs is referred to as an update point.
Update times for Redis scale nearly linearly with database keys, on the opposite end of the spectrum.
Kitsune Benchmarks » The best way to learn Kitsune is to follow the tutorial located in the /doc directory of the repository.
Existing DSU implementations vary widely in their treatment of update points.
In some systems, such as Up Stare and Po LUS, an update can occur at any time during execution.
Depending on the programmer's familiarity with the application, and the application's own degree of complexity, adding support for DSU using Kitsune can range from mild to difficult.
In our own experience, virtually all of the work required to add Kitsune integration with an existing project occurs in the first version.

After this point, the Kitsune support code becomes a separate concern. In all cases, the lines of code added to our benchmark programs to support Kitsune accounts for less than 1% of the total code.
