The purpose of this page is to give an overview of the EnforcerNG design, design decisions, and implementation details. For now however it will merely contain a dump of circulating documents.

Future work on EnforcerNG

Recommendation: Further work on profiling the enforcement of zones is required!

A decision was taken to re-factor the entire database layer in March 2014. Here are some suggestions for how the re-factor could be done:

• There has been some discussion on the developer list as to why and how the re-factor should be done. It is recommended that this page is used to hold design documents as the re-factor moves forward. It would be helpful from an architectural and knowledge sharing point of view if the following documents were created:
  • the architecture of the system immediately prior to the re-factor and the
  • the proposed design for the re-factor and the reasons for it
  • the actual design after the re-factor
• It is also proposed that a review team of at least 3 developers is involved in the re-factor as it progresses. This is to reduce the risk of 
  • a single developer making design decisions in isolation
  • ending up with a component that is only well understood by a single developer, which is clearly a risk for the project
  • sufficient documentation not being produced
• It is recommended that as many regression tests as possible are enabled before the re-factor is done to provide as much automated regression testing as possible
• It is also recommended that the benchmarking tests are improved and re-run as each of the stages of the re-factor are completed to ensure that the previous levels of performance are met or exceeded.
