Featherweight PINQ

Differentially private mechanisms enjoy a variety of composition properties. Leveraging these, McSherry introduced PINQ (SIGMOD 2009), a system empowering non-experts to construct new differentially private analyses. PINQ is an LINQ-like API which provides automatic privacy guarantees for all programs which use it to mediate sensitive data manipulation. In this work we introduce featherweight P...

Featherweight VeriFast

VeriFast is a leading research prototype tool for the sound modular verification of safety and correctness properties of single-threaded and multithreaded C and Java programs. It has been used as a vehicle for exploration and validation of novel program verification techniques and for industrial case studies; it has served well at a number of program verification competitions; and it has been u...

Featherweight Generic Ownership Technical Report

Featherweight Generic Ownership

Object ownership is an approach to controlling aliasing in programming languages. Proposals for adding ownership to programming languages do not directly support type genericity. We present Featherweight Generic Ownership — the first system to unify ownership and type polymorphism. Our type system extends Featherweight Generic Java with locations to support ownership and confinement invariants,...

Featherweight generic confinement

Existing approaches to object encapsulation either rely on ad hoc syntactic restrictions or require the use of specialised type systems. Syntactic restrictions are difficult to scale and to prove correct, while specialised type systems require extensive changes to programming languages. We demonstrate that confinement can be enforced cheaply in Featherweight Generic Java, with no essential chan...
