Community metrics/November 2012

Second issue of the MediaWiki community metrics monthly report!

We have added a bunch of bug tracking data in order to highlight some of the QA and testing activities. Hopefully next month we will show mediawiki.org data to reflect the documentation work.

Other news related with metrics:


 * Spanish company Bitergia has started generating automatic analysis reports about MediaWiki as a showcase of their set of open source tools.
 * The Signpost Technology Report: Code review statistics bounce back in October after difficult September.
 * ... and just in case you had missed bawollf's gerrit stats, check them out!

Code
The MediaWiki community includes about 506 code contributors active in the past 12 months. A total of 884 developers have contributed code to Wikimedia projects since the first MediaWiki commit in April 2003. The total sum appears to be 5,6M lines of code.

MediaWiki core
MediaWiki core is the largest project by far, with 925,424 lines of code written by a total of 338 contributors, from which 150 (was 140) have been active in the past 12 months.

Last month
 * 490 commits (was 698 in October, 498 in September).
 * Code contributions came from 54 contributors (was 56), including 7 new potential contributors.

12 months
 * 6898 commits (was 6927), down -472 (6%) from previous 12 months. The decrease probably is due to the different approach to commits on SVN (past) vs Git (now). Nothing to worry about, apparently.
 * 150 contributors (was 139), up +70 (87%) from previous 12 months. WMF hires and Git adoption might seem to be the main causes of this great increase. Some cases of multiple email addresses for one contributors are also suspected / expected. Still, it's a clear YoY increase.
