Introduction

  • Extends the Checker Framework

  • Currently supports inference of Universe Types, Ownership Types, Reference Immutability(reim), EnerJ, SFlow, DFlow and AJ.

  • Download: issta-artifact-2015.zip (144M) contains executable binary, or issta2015.zip (1.8G) contains executable binary and all benchmarks. NOTE: This is the implementation in the ISSTA'15 paper. Unzip it and follow the instructions in README.

  • Download: type-inference-0.1.2.zip contains executable binary and source code. NOTE: It contains Reference Immutability(reim), Ownership Types, and Universe Types in this zip file. Others will be added soon.

Installation

The following instructions assume an Unix-like (e.g Mac, Linux) environment.

Requirement: You must have JDK 6 or later installed. The binary release was compiled and tested under JDK 6 on Mac OS X 10.7 and Ubuntu 12.04.

  1. Download type-inference-0.1.2.zip and unzip it to create a type-inference directory
  2. Optional Add type-inference/binary to your PATH
  3. Test if installation is success. Open a command window and change the directory to type-inference. Run javac -version if you have added it to your PATH or ./binary/javac if you didn't, it should output: javac 1.7.0-jsr308-1.3.0

Example use: inferring Reference Immutability and Method Purity

This is the implementation in the OOPSLA'12 paper.

Suppose that we want to do the inference for one test case included in type-inference-0.1.2.zip: inference-tests/CellClient.java.

  1. Change the directory to type-inference
  2. Run ./binary/javai-reim inference-tests/CellClient.java

The inference results are dumped to:

  • new-result.jaif: The result in JAIF format containing fields, parameters and return values, but no local variables.
  • new-result.csv: The result for all variables.
  • new-pure-methods.csv: The pure methods inferred by the tool.

Run benchmarks used in the OOPSLA'12 paper

  1. Download 2012-oopsla-eval.zip
  2. Unzip it into two directories: 2012-oopsla-eval and benchmarks
  3. 2012-oopsla-eval �contains scripts for running the benchmarks
  4. benchmarks contains all benchmarks used in the paper except SPECjbb.
  5. Please make sure that JDK 6 is included in your PATH. JDK 7 would cause errors.
  6. Example: execute the script run-jolden-ri in 2012-oopsla-eval to run the benchmark jolden

Use Eclipse Plugin to infer method purity for Java projects

  1. Download the plugin and unzip it into plugins folder.
  2. Copy the folder plugins/edu.rpi.cs.reiminfer_1.0.0 into your Eclipse plugins folder.
  3. Add the following line in your eclipse.ini file: -Xbootclasspath/p:../../../plugins/edu.rpi.cs.reiminfer_1.0.0/lib/jsr308-all.jar
  4. In Eclipse, right click a Java project and select ReimInfer => Infer Pure Methods.

Build from source code

  1. Install Oracle JDK 6 and have JAVA_HOME set correctly. JDK 7 and up should be supported but we haven't tested it yet.
  2. Insatll Apache Ant.
  3. Build jsr308-langtools:
cd type-inference/inference-framework/jsr308-langtools/make
ant
  1. Build annotation-tools:
cd type-inference/inference-framework/annotation-tools
ant
  1. Build checkers:
cd type-inference/inference-framework/checker-framework/checkers
ant bindist
  1. (Optional) Build annotated JDK for some specific type system:
cd type-inference/inference-framework/checker-framework/checkers/jdk
vim Makefile

Edit Makefile and find the line like:

CHECKER_DIRS = sflow

Change sflow to other type system, e.g. reim. Then run

make

Lastly, copy the generated jdk.jar to type-inference/inference-framework/checker-framework/checkers (This is automatically done when you run ant bindist in step 5)

copy jdk.jar ../binary/
  1. Test run:
cd type-inference/inference-framework/checker-framework/checkers
# Run the inference of SFlow type system.
binary/javai-sflow

Instantiation of other type systems

Note: Inference results for detecting information violations in web apps are available: webapps-results.tgz. The instantiated inference will be released shortly (available in the source repository).
