When I send a pull request to Linus, I create a signed tag which createscontains a message about a set of commits, and this message is automatically included in the pull request message generated with "git request-pull", and when Linus merges my pull request, the cryptographically signed tag, along with the message, date of the signature, etc., is preserved for all posterity. > Problem: if pushing via an intermediary the push metadat would get > lost.

With signed tags, the metadata is preserved even when the set of commits is sent via an intermediary. It seems the major difference is that it's a pull model, where some projects seem much happier with a push model. But that sounds like what is needed is that someone replaces Linus Torvalds with a shell script --- namely, an e-mail bot that receives pull requests, checks the signed tag against an access control list, and if it is an authorized committer, accepts the pull request automatically (or rejects it if there are merge conflicts). Not that I am suggesting for even a second that Linus could be fully replaced by a shell script. For example, he handles trivial merge conflicts, and more importantly, applies a "oh my G*d you must be kidding" taste filter on incoming pull requests, which I think would be hard to automate. Then again, neural networks have automatically evolved to recognize cat videos, so we can't rule it out in the future. :-) Cheers, - Ted -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
