Heh. I was afraid to look at my own.
I wondered if we had a good way of finding who wrote the specific lines
that were changed in a patch. I wrote the script below before realizing
that contrib/contacts does something similar (though I think it blames
whole hunks, including context, and I really want to care specifically
only about touched lines; I wonder if that is a distinction git-contacts
should make).
Running:
git diff origin origin/jk/test-chain-lint |
perl diff-blame.pl jk/test-chain-lint |
grep EOF
was fun. At least I am not the only one. :)
Nor the worst in the "severe" category. I will leave using the script to
read the list of "severe" names as an exercise to the reader; reading
such output is probably not overly healthy (and besides, to be fair it
really should be normalized over the number of contributions).
