But I think fundamentally it comes down to: do you show the steps that went into the result, or do you squash them out into a clean history? > Gerrit cannot provide such a workflow easily as it's rather commit > centric and not branch centered.

One of the challenges is that the PR body is in Markdown, but we'd probably want "real" text in the merge commit. One option would be to simply convert Markdown->HTML->Text, which should provide a fairly clean version. It will take some playing with, but I'm going to see what I can do. > > I don't know offhand what Gerrit merges look like. > > Let's say it's complicated.

Usually I "format-patch -s" and then add any notes while sending. But the wifi at OSCON was so abysmal that instead I wrote the notes directly into the commit message to send the whole thing later. And of course format-patch is not smart enough to know that I meant everything after the "---" as notes. :) -Peff -- 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
