[gentoo-dev] Git copy detection (was: My masterplan for git migration...)

So Git works great, and GitHub's web UI doesn't support all of Git's bells and whistles, so… switch to a different VCS? Personally, my conclusion is “just use Git from the command line”. It's not like you're abandoning long years of experience using CVSHub with some miracle UI ;). Cheers, Trevor -- This email may be signed or encrypted with GnuPG (http://www.gnupg.org).

Personally, my conclusion is “just use Git from the command line”. It's not like you're abandoning long years of experience using CVSHub with some miracle UI ;). --find-copies-harder For performance reasons, by default, -C option finds copies only if the original file of the copy was modified in the same changeset. This flag makes the command inspect unmodified files as candidates for the source of copy. This is a very expensive operation for large projects, so use it with caution. Giving more than one -C option has the same effect. P.S. As you see from description this option affects git performance. So, we probably can arrive at a conclusion that git itself isn't good at all for package management. Maybe there are better architectural decisions for that.

You're doing more because you want to get more out. Or did you expect git to find potential copies from your whole repository for /no/ increase in performance cost? That's why it defaults to off, for performance.
