A Cross-platform Analysis of Bugs and Bug-fixing in Open Source Projects: Desktop v. Android v. iOS
Description
In this paper we focus specifically on differences in bugs and bug-fixing processes between desktop and smartphone software. Our study covers 444,129 bug reports in 88 open source projects on desktop, Android, and iOS.Examined Projects
The following table shows the projects we use in our research, also issue tracking system each project use.Projects with * in the last moved both source code repository and issue tracking system to GitHub. Projects with ## in the last only immigrated source code repository to GitHub.

Appendix Data
Datasets This is the data sets we used for the quantitative analysis (The datasets used for topic modeling are too large to put it online).Feature distribution for each project over time In this folder, we plot the distribution overtime for each feature of each project. Here is an example:
This plot shows the distribution of geometric mean of FixTime per month for project SeaMonkey on desktop.
Geometric mean of features for each project This excel file includes geometric mean of bug-fixing process features, e.g., FixTime, as well as features' crossponding trend (beta) for each project on both platforms.
Geometric mean of bug-fixing metrics for each project This excel file includes geometric mean of bug-fixing metrics, e.g., TurnoverReporter, as well as metrics' crossponding trend (beta) for each project on both platforms.
Topic extracted for each platform This excel file includes top-5 topics every year for each platform. We also show the keywords for each topic and topic label signed by us.
