New Features

  • Add side-effect analysis.
  • The options --class-path and --app-class-path can be repeated multiple times to specify multiple paths.
  • Pointer analysis
    • Add Plugin.onPhaseFinish().
    • Support specifying multiple method signatures in one @InvokeHandler annotation.
    • Add getInfo() to call graph edges and pointer flow edges.
    • Add pointer analysis assertion mechanism to ease testing.
    • Add pascal.taie.analysis.pta.plugin.util.AnalysisModelPluginand IRModelPlugin to replace original Model and IRModel, provide more convenient interfaces to support @InvokeHandler.
  • Taint analysis
    • Support specifying IndexRef (e.g., index: "0[*]" and index: "0.f") in call sources and parameter sources.
    • Support specifying IndexRef in sinks.
    • Support interactive mode, allowing users to modify the taint configuration file and re-run taint analysis without needing to re-run the whole program analysis.
    • Enhance TFG dumping by adding taint configuration and call site info to Source/Sink node and TaintTransfer edge.
    • Support programmatic taint config provider.
    • Add commonly used taint configurations.
  • Class hierarchy analysis (CHA)
    • Support ignoring call sites that call methods declared in java.lang.Object.
    • Support ignoring call sites whose callees exceed given limit.
  • Signature pattern and matcher
    • Add pascal.taie.language.classes.SignatureMatcher which supports retrieving classes, methods, or fields whose signature match given pattern.
    • Use signature matcher in taint analysis and @InvokeHandler to simplify signature configuration.

Breaking Changes

  • API changes
    • Change Solver.addPFGEdge(Pointer,Pointer,FlowKind,Type) and Solver.addPFGEdge(Pointer,Pointer,FlowKind,Transfer) to Solver.addPFGEdge(PointerFlowEdge) and related APIs.
    • Deprecate pascal.taie.analysis.pta.plugin.util.Model and IRModel (these two interfaces are currently preserved for compatibility, and will be removed in the future).
    • Change PrimitiveType from enum to an interface and implement it by classes that represent concrete primitive types. Refine the types of certain expressions from PrimitiveType to the concrete primitive types.

Fixes

  • Fix incorrect classpath argument for the frontend where the -acp option is not being used. This issue is only reproducible when --prepend-JVM (-pp) is set to true.
  • Fix mismatch between number of parameter names and number of actual parameters in JMethod for inner class.
  • Fix option parser, now treat only the first colon as delimiter between a key and a value (before each colon is treated as delimiter).
  • Fix empty log file when running via JAR.
