App store reviews are currently the main source of information for analyzing different aspects of app development and evolution. However, app users' feedback do not only occur on the app store. In fact, a large quantity of posts about apps are made daily on social media. In this paper, we study how Twitter can provide complementary information to support mobile app development. By analysing a total...
In-spite of the principle of good programming practice which stipulates that a commit should include only modifications belonging to one task, programmers submit tangled commits consisting of modifications related to two or several distinct tasks. Some researches show that between 11 and 39% of bug fix commits are tangled and at least 16.6% of all the commits are incorrectly associated to bug reports...
A software bug repository not only contains the data about software bugs, but also contains the information about the contribution of developers, quality engineers (testers), managers and other team members. It contains the information about the efforts of team members involved in resolving the software bugs. This information can be analyzed to identify some useful knowledge patterns. One such pattern...
We mined the issue database of GNOME to assess how issues are handled. How many issues are submitted and resolved? Does the backlog grow or decrease? How fast are issues resolved? Does issue resolution speed increase or decrease over time? In which subproject are issues handled most efficiently? To answer such questions, we apply several visualization and quantification instruments to the raw issue...
Software repositories are analyzed to extract useful information on software characteristics. One of them is external quality. A technique used to increase software quality is automatic static analysis, by means of bug finding tools. These tools promise to speed up the verification of source code; anyway, there are still many problems, especially the high number of false positives, that hinder their...
Developers of open source projects are distributed across the world. They rely on email, mailing lists, instant messaging, IRC channels and more recently IRC meetings to communicate. Most of the studies thus far focus on the use of mailing lists by OSS developers, however, an increasing number of open source projects are using IRC meetings to hold developer meetings. In this paper, we mine the #gtk-devel...
