1 The Harmony Framework

2 Empirical Software Engineering Ask a question Design an experiment Measure on real data Analyze the results

3 Performing studies Controlled experiments Expensive Mainly students, not the same as experienced developers Analyzing development repositories Cheap Mainly open-source projects, not the same as industrial projectsd Different type of repositories, hard to gather

4 How to get development data Push mode the data model is built at development-time by extracting data after each commit Queries can readily be written, but relevant data might lack Browse mode the data model is built on-demand by browsing the development repositories Extracting the data is long, but fine-tuned analyses are possible

5 Without Harmony Are library migrations frequent? Cédric Open Data... Repository 1 Repository 2 Repository 3 Repository 4 Repository n

6 With Harmony Cédric's Harmony analysis 4 % of the studied repositories performed at least one migration Harmony Framework Open Data.. Repository 1 Repository 2 Repository 3 Repository 4 Repository n.

7 Harmony goal Ease the analysis of development data based on a browse approach

8 Main features Repository independent analysis code. Write once, run everywhere. Analyses are reusable. There is a dependency mechanism between them, and they can communicate using the whiteboard paradigm Harmony core take care of the scheduling, multi-threading and persistence

9 Harmony Architecture and features ReportingAnalysis ClocAnalysis IAnalysis Harmony Core // ISourceExtractor GitSourceExtractor SVNSourceExtractor YourAnalysis HgSourceExtractor OSGi Runtime

10 Demo Step 1 : Harmony installation Step 2 : Launching an existing analysis Step 3 : Extension of the analysis to answer a new question

11 Step 1 : Harmony installation Download Eclipse Eclipse Classic : 422/junosr2 Install Harmony Add Update site : Install all the components from this update site Import Harmony bundles into your workspace (Import Plugins and Fragments Active target platform select Harmony core and analyses)

12 Step 2 : Launching an analysis Run configurations Harmony Equinox Type harmony in the OSGi console Wait and see...

13 Step 3 : Extension of the analysis Modification of ReportAnalysis.java to analyze more data Save and back to step 2 for execution
