Mining Software Repositories

Mining Software Repositories What to do? And where to get data? Israel Herraiz < [email_address] > Universidad Alfonso X el Sabio June 18 th 2010

Outline
What is Mining Software Repositories? What are repositories?
Conferences and journals of interest
And some words about trending topics
Tools for Mining Software Repositories
Datasets for Mining Software Repositories
For replicable and verifiable empirical studies

1. What is Mining Software Repositories?

What is Mining Software Repositories?
MSR analyzes the rich data available in software repositories to uncover interesting and actionable information about software systems and projects.
Popular topic since 2004
MSR workshop, colocated with ICSE
Working Conference since 2008

What are repositories?
Anything that leaves a trail about any software development or maintenance activities
Also includes any software artifact
Tipically
Version control systems
Bug tracking systems
Public communication tools (mailing lists)

Differences between artifact and repository #include <stdio.h> int main() { printf(“Hello world”); return 0; } Artifact Source code file hello.c - printf(“Hello world”); + printf(“Hello world ”); Author: rms Date: 20100618 04:34 UTC Change: +1 -1 Log: Forgot to add new line hello.c.diff Repository Change to an artifact Meta-information

4. Datasets for Mining Software Repositories

MSR Mining Challenge
Mirrors of the version archives and bug databases for Mozilla Firefox and Eclipse
http://msr.uwaterloo.ca/msr2008/challenge/
Repository logs of over 500+ Gnome projects, XML dump of the bug databases, and the complete SVN repositories of 69 Gnome projects
http://msr.uwaterloo.ca/msr2009/challenge/

Ultimate Debian Database
Database with information about packages and bug reports of Debian and Ubuntu
http://udd.debian.org/

Eclipse bug database
Saarland University
Datasheets, databases, scripts, with information about Eclipse bug reports for several releases
http://www.st.cs.uni-saarland.de/softevo/bug-data/eclipse/

FLOSSMetrics
Databases about ~5000 open source projects
Control version repositories, mailing list archives, bug tracking databases
MySQL dumps
Not very user friendly
Obtained using the Libresoft Tools
http://www.flossmetrics.org/

FLOSSMole
Database with information about all the SourceForge.net projects
~150,000 projects
Mainly metainformation, obtained through parsing the web pages of the projects
No low level or fine grained information
http://flossmole.org
