PROJECTS © Marcelo d’Amorim 2010
Project P 1 • Symbolic executor instrumenter using Jimple © Marcelo d’Amorim 2010
Project P 2 • Query Language (LTL or ERE) – Example “A (f. open() => E (f. close()))”, where A means Always, and E means Eventually © Marcelo d’Amorim 2010
Project P 3 • API rule mining (conceptually, inverse of P 2) – Example: • API calls: “Whenever you call this method you eventually call that” © Marcelo d’Amorim 2010
Project P 4 • Lightweight slicing – “What lines of the program are relevant to violate state assertion? ” – Hypothesis: O 1 • Several parts of the state (and thus locs) are irrelevant (see blue cells) O 1 O 2 O 3 O 4 O 5 {10, 15} O 2 {20} O 3 O 4 {25} O 5 Transitive closure on this relation from faulty object(s), say o 1. © Marcelo d’Amorim 2010
Project P 5 • Behavior-preserving differencing – Question: Which static changes affect behavior? – Input: Two source bases, output relevant changes – Several approaches… © Marcelo d’Amorim 2010
Project P 6 • Extract interfaces for feature modularization © Marcelo d’Amorim 2010
