I'd like to announce a project I've been working on for a while:

git-series provides a tool for managing patch series with git, tracking
the "history of history". git series tracks changes to the patch series
over time, including rebases and other non-fast-forwarding changes. git
series also tracks a cover letter for the patch series, formats the
series for email, and prepares pull requests.

Just as an FYI, I wouldn't be surprised if there's some overlap, or
potential for merging of tools, between this tool and the "patman" tool
that's part of the U-Boot source tree:

http://git.denx.de/?p=u-boot.git;a=blob;f=tools/patman/README;h=e36857dedea1d0dbafa41732aaf9bf0988d63f38;hb=HEAD

Interesting tool; thanks for the link.

As far as I can tell from that documentation, patman doesn't track old
versions of a patch series; you rebase to modify patches or change
patman tags (embedded in commit messages), and nothing preserves the
previous version.  And it tracks the cover letter and similar in one of
the commit messages in the series, so previous versions of that don't
get saved either.  If you wanted to track the history of your changes,
you'd have to use branch names or similar.

That's right. Normally you would keep the old branch around, or tag
it. Of course old branches are often based on older versions the
upstream repo, so they are not that useful for diiff, etc. But the
normal procedure when updating a series to a new version is:

git checkout -b wibble-v2 wibble
git rebase upstream/master
git commit --amend
# Edit commit to add 'Series-version: 2', update cover letter etc.

Of course any change log is preserved when you move to v3, since you
just add more 'Series-changes:' tags. The old version of the cover
letter, and the old version of the commits can be preserved with 'git
tag'.

In addition, tracking metadata in commit messages only works with a
patches-by-mail workflow where the messages get processed when
generating patches; that doesn't work for please-pull workflows.

Can you explain what a please-pull workflow looks like, and what tags
are expected?

patman does have quite a few interesting ideas, though.  git-series
needs some way of handling To/Cc addresses for patches and the cover
letter (beyond just scripts/get_maintainer.pl), and more automatic
handling of series versioning (v2, v3, ...) and associated series
changelogs.  Suggestions welcome.

Patman builds the cover letter change lists from the commits. The main
point of patman is to automate the error-prone process of submitting a
perfectly formed patch series.

In particular, patman requires no change to the normal workflow that
people use with git.
