TBar

Template-based automated program repair

I. Requirement

• Java 1.7
• Defects4J
• GZoltar
• SVN >= 1.8
• perl >= 5.0.10

II. Overview of TBar

III. Docker (which probably checks out its own D4J)

The docker image of TBar is available: TBar.

IV. Run TBar

Chart_8.zip is included in this repository as a sample D4J bug for testing.

---

1. Fixing Defects4J bugs with perfect fault localization configuration.

• ./PerfectFLTBarRunner.sh <Bug_Data_Path> <Bug_ID> <defects4j_Home> <true/false>

  Example: ./PerfectFLTBarRunner.sh D4J/projects/ Chart_8 D4J/defects4j/ false to fix bug Chart_8 with perfect fault localization configuration.

  ./PerfectFLTBarRunner.sh D4J/projects/ Chart_8 D4J/defects4j/ true tries to fix bug Chart_8 with all possible matching fix patterns.

2. Fixing Defects4J bugs with normal fault localization configuration.

• ./NormalFLTBarRunner.sh <Bug_Data_Path> <Bug_ID> <defects4j_Home>

  Example: ./NormalFLTBarRunner.sh D4J/projects/ Chart_8 D4J/defects4j/.

If it executes failed because of the paths of <Bug_Data_Path> and <defects4j_Home>, please use their absolute paths.
