That's one way to solve this, but it would still be just a half of a

There are still edge cases that can bite us in the future - legal change
of the name, someone who has a typo in the gitconfig just on one of the
machines - that ends up propagating to other patches (I've seen this

That's why I am strongly in favor of keeping "From" with each of the
patches - it matches intuitive understanding of patch being self

Tests are in patchwork/tests/ subdirectories.

You would quite likely want to implement new tests for "mboxviews" to
make sure which person is used in the From line in the generated mbox.

And another one for mail parser to make sure it parses and handles
authorship correctly.

Those are just regular django unit tests. You can look up details in
their documentation.

Please base you work of this branch:

Check out the docs/ directory. There is installation and development

I am running one internal instance locally that I use to test the
changes with real workloads from mailing lists. I would deploy it there
for a couple of days before going with freedesktop deployment.

Sadly I am the only contributor as of now, and I would love to have
someone else to review my work especially if that person helps me with
the development from time to time.

I have my own fork on github, but I always push the changes to Damien's
repo when they are "production ready".

Quite likely this is not going to happen in the foreseeable future.
Freedesktop forked quite a while ago. I was told that back then the
patchwork project was not very keen on the direction of changes - UI
revamp, automatic grouping patches in series and REST API instead of
just XMLRPC, hence the fork.

Now they are starting to catch up with features, but IMO they are in
much rougher shape, usability-wise. Series are a second-class concept
and are not nearly as functional as what freedesktop has, and the
REST API looks very different and misses some of the key pieces.

IMHO it's less effort to maintain the fork.
