I've been looking into the Github commit history of Bitcoin. I have no clue how git works, but interestingly, I'm seeing a number of developers' mail addresses associated with commits of others.

For example, Luke-Jr and Gavin Andresen's account emails have both signed commits under Wladimir's name when I run this command:

git log --all --format='%aN,%cE' | sort -u;

What gives?

  • Can you please specify/clarify what is the question? This seems more like a post than a question – sanket1729 Jun 8 '17 at 10:36
  • Yea. Why are the bitcoin developers signing with cross-linked names and addresses? – nick carraway Jun 8 '17 at 17:57
  • Fyi, I ran this command to get the e-mails, within the bitcoin github directory: git log --all --format='%aN,%cE' | sort -u; – nick carraway Jun 8 '17 at 17:58
  • Correct, the command fetches the e-mails. I don't really about the regex in command, but I manually examined the git log where I am not able to spot these pairs. – sanket1729 Jun 9 '17 at 5:33

    I think something different happens when you squash the commits from multiple authors. I encourage you to manually examine the logs to convince yourself – sanket1729 Jun 9 '17 at 5:35

What you are seeing has nothing to do with git history manipulation nor with blockstream. It is related to your choice of format specifier. You chose to use %aN,%cE which means author name, committer email. However, in git, the author and the committer are not necessarily the same person. The author is the person who wrote the patch and the committer is the person who actually adds the patch to the repo. This happens in Core with backports. Someone (the author) writes the patch which gets merged into the master branch of the repo. Later someone else (the committer) uses git cherry-pick to pick the specific commits that made those changes and backport them to a previous version to be later released as a new minor version. The nature of git cherry-pick is that the author of the patch is preserved, but the committer becomes the person who performed the cherry-pick. This is what is causing the discrepancy in your list.

An accurate list of authors and emails would be done using

git log --all --format='%aN,%aE' | sort -u

Running that command gives me the following output:

As you can see, there isn't any of the duplication or discrepancy that you posted about. The duplication here comes from different spellings/versions of people's names (e.g. I use Andrew Chow, Andrew C, achow101, or Andrew) and from the same person using different emails.
