v0.76 contributors credits (beta)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Ceph,

Here is a sorted list of authors and organizations who contributed to v0.76, by number of commits or reviews back to v0.75. The affiliation of authors to organizations can be updated by submitting a patch to https://github.com/ceph/ceph/blob/master/.organizationmap

All commits are reviewed but the number of reviews is a fraction of the number of commits. More often than not, the reviewer(s) is only mentioned in the message of the merge although it means that all associated commits have been reviewed. 

If you are curious about how it is done, the details are at the end of this mail.

The script used to generate this output is (copy paste at the root of a git clone https://github.com/ceph/ceph.git):

cat > credits.sh <<'EOF'
range=$1
echo "Commits by authors"
git log --pretty='%aN <%aE>' $range | sort | uniq -c | sort -rn | nl
echo "Commits by organizations"
git log --pretty='%aN <%aE>' $range | git -c mailmap.file=.organizationmap check-mailmap --stdin | sort | uniq -c | sort -rn | nl
echo "Reviews by authors (one review spans multiple commits)"
git log --pretty=%b $range | perl -n -e 'print "$_\n" if(s/^\s*Reviewed-by:\s*(.*<.*>)\s*$/\1/)' | git check-mailmap --stdin | sort | uniq -c | sort -rn | nl
echo "Reviews by organizations (one review spans multiple commits)"
git log --pretty=%b $range | perl -n -e 'print "$_\n" if(s/^\s*Reviewed-by:\s*(.*<.*>)\s*$/\1/)' | git check-mailmap --stdin | git -c mailmap.file=.organizationmap check-mailmap --stdin | sort | uniq -c | sort -rn | nl
EOF
bash credits.sh tags/v0.75...tags/v0.76

Authors names are normalized with .mailmap and authors affiliations to a given organization comes from .organizationmap, both of which can be found and patched at the root of the ceph source tree.

More sophisticated reports can be generated and visualized by tools such as http://bitergia.com/ or http://stackalytics.com/. 
Cheers
