Local reasoning about storable locks
Josh Berdine · 2007
This talk will present a resource-oriented program logic that is able to reason about concurrent heap-manipulating programs with unbounded numbers of dynamically-allocated locks, and note an extension to storable threads. The logic is inspired by concurrent separation logic, but handles these more realistic concurrency primitives. We demonstrate that the proposed logic allows for local reasoning about programs that exhibit a high degree of information hiding in their locking mechanisms. Soundness is proved using a novel thread-local fixed-point semantics.
