[ade]'s Diary: What Have We Done?

What Have We Done?

How far, how fast, how big has the KDE project grown? It's a question that interests various folks at various times. Thiago has a nice graph of commits-per-month somewhere, but he stopped updating it at some time. I've just slapped together some new graphs with kst (extragear-graphics, and rather clunky to use). Here they are.

This teensy graph (click for full-size version) shows the number of commits per month (well, per four weeks) since the inception of the KDE project on October 16th 1996 (really? there's no date on the original announcement linked from kde.org). It took some time before the codebase was in CVS, though. Note the nice linear growth in the number of commits, which means (for those of you who didn't take calculus) that KDE is growing quadratically. Huzzah!

I should add: don't try this at home, kids. I have 117M of SVN logs and extracted data. If you want it, don't hit the server for it but ask me and I'll send out a copy.

Two other lines in the graph show Coolo's commits-per-month (since forever, and always, and consistently large) and my own humble contribution as well (since january 2000 and not at all consistent). It shows that programmers don't scale very well, at least not in numbers of commits.

That's all for this week's useless bit of stats, tune in next week when we examine whether Christmas and new year have an effect on the rate of KDE development.

Very neat, any way to extract the number of commits that have BUG: in them etc?

That's pretty cool. It's interesting that the rise is so linear - I would have expected to see a drop of during the KDE 2 development period which was very long.

Here is another method for retrieving the number of commits (with the distorsion of additional replies):

Interesting graph!
I'm wondering why your commits / month rate differs so much from the number of commit mails Carlos pointed at (http://kde.mcamen.de/kde-svn.png). Do you count the number of commits or the number of comitted files? What about scripty?

Posted by: Marcus Camen at August 23, 2005 07:19 PM

Marcus: I count 4-week increments, not the whole month, and as Carlos already pointed out, there's also replies to the -commits messages that inflate the numbers there. I'll just have to brush up the scripts some more, also to satisfy Ben's curiosity.

Sadly, this is not really a good sign, especially if our bug count keeps increasing along with number of commits... 9500+ bugs ... it doesn't look like those commits are happening where they really should.
