Android Open Source Project (AOSP) Community Stats

Last modified : 12 July, 2017

Here’s a thought. How open-source is Android really? To find out, I went through the instructions of downloading the entire AOSP source code. I’ve always wondered what people who have worked for Google think about having all the source code under a single repository. I’m guessing some probably like it. I don’t know if its painful but not painful enough to actually fix it. Or do the vast majority like it? I could see it both ways.

Anyway, after 54G of code repositories being downloaded, I ran this

AOSP $ for i in `find $(pwd) -name .git -type d`; do cd ${i}; cd ..; git log | grep Author | head -n 100 >> ~/androidauthors; done

Basically find the last 100 (non-distinct) authors in each of the git repositories and dump them to a file. I know this is inaccurate. The number of commits is not a good measure of level of contribution. And what if the repo has < 100 commits? And what if the timeframes were wildly different across repos. etc. etc. But I wanted a query that would be fast and approximate. Please let me know if you’d like a better query.

Now for finding the contribution per company.

~ $ cat androidauthors | cut -d\@ -f2 | cut -d\> -f1 | sort | uniq -c | sort -r -n | head -n 15

How about individuals?
