Towards Run-time Checks Simplification via Term Hiding

Authors: Nataliia Stulova, Jose F. Morales, and Manuel V. Hermenegildo

Published in: OASIcs, Volume 58, Technical Communications of the 33rd International Conference on Logic Programming (ICLP 2017)

Abstract
One of the most attractive features of untyped languages for programmers is the flexibility in term creation and manipulation. However, with such power comes the responsibility of ensuring correctness of operations. A solution is adding run-time checks to the program via assertions, but this can introduce overheads that are in many cases impractical. While such overheads can be greatly reduced with static analysis, the gains depend strongly on the quality of the information inferred. Reusable libraries, i.e., library modules that are pre-compiled independently of the client, pose special challenges in this context. We propose a relaxed form of atom-based module system (which hides only a selected set of functor symbols but still provides a strict mechanism to prevent breaking visibility rules across modules) that can enrich significantly the shape information that can be inferred in reusable modular programs. We also propose an improved run-time checking approach that takes advantage of the proposed mechanisms to achieve large reductions in overhead, closer to those of static languages even in the reusable-library context. While the approach is general and system-independent, we present it for concreteness in the context of the Ciao assertion language and combined static/dynamic checking framework. Our method maintains full expressiveness of the checks in this context. Contrary to other approaches it does not introduce the need to switch the language to (static) type systems, which is known to change the semantics in languages like Prolog. We also study the approach experimentally and evaluate the overhead reduction achieved in the run-time checks.

On Improving Run-time Checking in Dynamic Languages

Authors: Nataliia Stulova

Published in: OASIcs, Volume 58, Technical Communications of the 33rd International Conference on Logic Programming (ICLP 2017)

Abstract
In order to detect incorrect program behaviors, a number of approaches have been proposed, which include a combination of language-level constructs (procedure-level annotations such as assertions/contracts, gradual types, etc.) and associated tools (such as static code analyzers and run-time verification frameworks). However, it is often the case that these constructs and tools are not used to their full extent in practice due to a number of limitations such as excessive run-time overhead and/or limited expressiveness. The issue is especially prominent in the context of dynamic languages without an underlying strong type system, such as Prolog. In our work we propose several practical solutions for minimizing the run-time overhead associated with assertion-based verification while keeping the correctness guarantees provided by run-time checks. We present the solutions in the context of the Ciao system, where a combination of an abstract interpretation-based static analyzer and run-time verification framework is available, although our proposals can be straightforwardly adapted to any other similar system.
