Liveness Properties-Software Lifecycle

Liveness Properties: A liveness property asserts that something good eventually happens, and is used mainly to ensure progress. Liveness properties prevent:

  • starvation: Processes not getting the resources they need (e.g., CPU time, locks)
  • dormancy: Waiting processes fail to be awakened
  • premature termination: Processes killed before they are supposed to be

In general, liveness properties are harder to detect than safety properties.
