HSFL

This is the page for HSFL (Historical Spectrum based Fault Localization). You can replicate the experimental results reported int the submitted paper.

It contains the following file and folders:

./Survey.pdf

This file contains the complete results of our empirical survey conducted at Microsoft. We did not report the results in the submitted paper due to page limit.

./HSFL

This folder contains the implementation of HSFL, and the scripts to run all the experiments. Please go to this folder for further information.

./Chart

This folder contains the data for all the bugs in subject Chart.

./Chart/Chart_1

This subfolder contains the data for bug Chart 1

[the followings are generated by the baseline tool mentioned in the paper]

1. ./Chart/Chart_1/SBFL: it contains the results of conventional SBFL for different techniques.

[the followings are generated by the HSFL, which can be regenerated using the scripts provided in folder ./HSFL]

1. ./Chart/Chart_1/HSFL: it contains the results (i.e., the rankings of the suspicious statements together with their suspicious values) of HSFL and the component Histrum for different techniques.

2. ./Chart/Chart_1/a7cc1cf88cb014e937a55af53ea1f96407688a5e: this is the inducing change of this bug, and it contains the covered lines of the failing tests running on the bug-inducing version.

3. ./Chart/Chart_1/fileindexes: this folder contains file indexes for each suspicious buggy source file. Specifically, it stores all the versions starting from the bug-inducing version to the target version for each suspicious buggy source file.

4. ./Chart/Chart_1/mapping: this folder contains the historical spectrum for each suspicious buggy source file constructed starting from the bug-inducing version to the target version based on the historical versions in folder fileindexes.

[the followings are generated using Git]

1. ./Chart/Chart_1/classCommits.txt: this file records the information of a set of commits that modify the source file for all the source files in the project.

2. ./Chart/Chart_1/logFilesChanged.txt: this stores the information of version histories for the project.

3. ./Chart/Chart_1/logFullDescription.txt: this stores the information of version histories for the project.

4. ./Chart/Chart_1/logOneline.txt: this stores the information of version histories for the project.
