About this document

This document is a R notebook, dynamically created from the numbers extracted on the project. It lists all datasets published for the project, providing basic numbers, figures and a quick summary, and serves as a test case to make sure that all the required data is present and roughly consistent with requirements. All plots and tables are computed from the actual data as provided in the downloads.

To re-execute the document, simply start a R session, load rmarkdown and render the page with the project ID as a parameter:

require('rmarkdown')
render("datasets_report.Rmarkdown", params = list(project_id = "technology.paho"), output_format="html_document")

This website uses the blogdown R package, which provides a different output_format for the hugo framework.

This report was generated on 2022-08-14.

Downloads

All data is retrieved from Alambic, an open-source framework for development data extraction and processing.

This project’s analysis page can be found on the Alambic instance for the Eclipse forge, at https://eclipse.alambic.io/projects/technology.paho.

Downloads are composed of gzip’d CSV and JSON files. CSV files always have a header to name the fields, which makes it easy to import in analysis software like R:

data <- read.csv(file='myfile.csv', header=T)
names(data)

List of datasets generated for the project:

  • Git
    • Git Commits (CSV) – Full list of commits with id, message, time, author, committer, and added, deleted and modifed lines.
    • Git Commits Evol (CSV) – Evolution of number of commits and authors by day.
    • Git Log (TXT) – the raw export of git log.
  • Bugzilla
  • Eclipse Forums
    • Forums Posts (CSV) – list of all forum posts for this project.
    • Forums threads (CSV) – list of all forum threads for this project.
  • Jenkins CI
  • Eclipse PMI
    • PMI Checks (CSV) – list of all checks applied to the Project Management Infrastructure entries for the project.
