ChangeLog

Changes since Release 1.1.2:

• New features
  • Enhance reflection support
    • Evaluate Class.forName() on a string constant.
    • Evaluate Class.newInstance on a class constant.
    • Improved support for Constructor.newInstance and friends.
    • Basic support for Method.invoke
  • Improved support for Apache Struts analysis
• Code cleanup
  • Delete obsolete and broken OneCFABuilder. Use nCFABuilder with n==1 instead.
  • Fix overly expensive hash functions for Heap Statements.
  • Delete obsolete class SDGView.
  • More generics.
  • Generalize ReceiverInstanceContext to support subclassing.
  • Delete redundant PointerFlowGraph. Use CISDG instead.
  • Simplify MethodTargetSelector and ContextSelector interfaces; delete optimizations based on allSitesDispatchIdentically and mayReturnSyntheticMethod. This may slow down RTA, but I think the simpler API is worth it.
  • Nuke expensive ResolutionFailure
  • Delete half-baked logic package
  • Delete obsolete, half-baked support for ExplodedSupergraph traversal
  • Restructure tabulation handling of multiple return sites
• API Changes
  • Generalize tabulation solver to support partially balanced problems.
    • replace TabulationProblem.getReachableOnEntry() with TabulationProblem.initialSeeds()
    • new classes PartiallyBalancedTabulationProblem and PartiallyBalancedTabulation
  • Revamp slicer to use general partially balanced tabulation
    • Add new statement type MethodExitStatement, used to fake entry to callees in backwards slicing problems
  • Delete ill-conceived IClass.isStatic()
  • Change some APIs that returned Collection to return Set instead
  • Small changes to AbstractJavaAnalysisAction
• Bug Fixes
  • Bug fix in ShrikeCFG computing exceptional edges for catch blocks when the caught exception type is not resolved.
  • Bug fix in ModRef.ModVisitor.visitPut() for corner case.
  • Patch [1900368] bug fix for OrdinalSet.unify
  • More consistent use of HashSetFactory and HashMapFactory
  • Bug fix for synthetic methods with phi statements
  • Bug fixes for modelling of System class initializer
  • Handle a FileNotFoundException in EclipseProjectPath
  • Misc. bug fixes for corner cases in reflection
  • bug fix for equals/hashCode on SyntheticMethod
  • bug fix for BFS over empty graphs
  • bug fix for type inference of values from SSAComparisonInstructions
  • bug fix in BypassMethodTargetSelector to treat canIgnore condition consistently
  • fix data race in ReferenceCleanser that manifested as null pointer deref
