I have signed commits turned on, but if I take a commit that is even verified by github, (and looks great with `git show --show-signature`), I have no way how to send them using send-email so that the signing is preserved. Would be nice to know if there's a way.Based on what I've read, I don't think signatures can work with an email based patch workflow, nor with a fast-forward based process. If someone signs a patch, IIUC that covers the body, the comit message, and all the metadata including committer and author fields and parent commit hash. When you send a patch and then a reviewer applies the patch, the committer field gets changed to name of the person applying it. The parent commit hash also gets changed to whatever is HEAD when you apply it. Both these changes neccessarily invalidate any signature that could be attached to the mail. The only way I can see signatures working is if you exchange patches using "git bundle" so you're sending the full git object, not just a patch file. This will neccessitate you using merge commits in the repository, not fast-forward. So commit signatures look unusable for a development model based around exchange of patches on the list as libvirt does. They could be used to some extent with a sub-maintainer model, but only the sub-maintainers would be able to sign commits, for those going into the pull request. Individual contributors still wouldn't be able to sign in general since sub-maintainers just pull patches off the mailing list and git am them - only the final pull requests as done with merge commits.
Sure, I never meant the commits should stay signed. It doesn't really make much sense in most scenarios to have individual commits signed. Signed tag is an inherent sign for all parent commits, which is more than enough. What I wanted to have established was a way for the people receiving the commit to be able to see that it really came from me and it was not tampered with. For that case I only care about the medium (through which the commit is sent) to be covered. That's the only part of the chain where I'm missing some effort to enhance integrity and accountability.
