Contributors to Drupal 7.x - Code Freeze Looming Update

The code freeze for Drupal 7.x is looming large on the horizon. From that point on we will be limited in what kinds of changes we can get into Drupal core. For some the code freeze is a time of relief: it means we are down to bug fixes and the final release should be coming soon. For others it is a hard time - bug fixing isn't always as fun as adding new features.

So, as we head into feature freeze it seemed like a good time to run some statistics on who has been contributing the most to Drupal 7.x so far.

Contributors to Drupal 7.x. Through August 10th

Following on from previous times that I've run these stats, I've published documentation of the process to get the data on groups.drupal.org. This time I went straight to the commit messages stored in database tables on drupal.org This has the benefit of counting new files as well as old files (the last times I did this it only counted changes to existing files).

So, who are the top 10 people based on the number of times their name is in a commit message?

Name Commit mentions
Damien Tournoud 192
catch 179
chx 123
pwolanin 113
Dave Reid 109
boombatower 95
yched 77
c960657 57
drewish 56
Berdir 56

The total number of mentions is 3133, so those top 10 are responsible for roughly 33% of the code. On the flip side, people with 3 or fewer mentions are responsible for roughly 15% of the code. We still have a long tail of 222 people who are mentioned in only one message. We see a fairly typical "long tail" distribution: the people who are most involved do a lot of the work, but the people who only get mentioned a few times each are still responsible for a large number of commits when aggregated together.

The current number is at 469 contributors to Drupal 7. That's good, but we'll need about 300 more to beat the number for Drupal 6.x One concern from adding simpletests to Drupal 7 was that it might lock people out of the process. I don't think that's the case, but it will be interesting to see how things go as the code freeze passes.

Mashup the data

I've posted the parsed data as a CSV file to groups.drupal.org and a Google Spreadsheet so that other people can download it and look for other bits of information.

In January 2009 I did a similar analysis: Drupal 7: Who is Providing Patches for the Next Release?.
