Systemd moved it's canonical git repository to github last year. It seems that the traffic on the bug tracker is quite heavy, but impressions can be misleading. I wanted to know how many issues have been filed, and what percentage of has been actually resolved. Thanks to the github API (and pandas+matplotlib) it easy enough to generate a plot.

Blue and green lines are the total number of issues and the number of closed issues, number of the left y-axis. Red line is the difference, number on the right axis. The number of issues is growing linearly. Overall, we aren't doing too bad, 85% of issues have been closed.

The pattern for pull requests looks even better. 97+% of pull requests have been closed. Again, total and closed left y-axis, open right y-axis.

Raw numbers are a bit misleading though, because most requests are duplicates: github cannot handle updates to existing commits in a pull request without losing comments made on the old commits, so if changes to commits are necessary, we ask contributors to close the pull request and open a new one. Sometimes this happens four or more times, which of course inflates the counts.

A significant drop in the last few days is visible: this is an effort by Daniel Mack and Lennart Poettering to trim the number of outstanding issues and pull requests.
