This will make editing states through the admin UI less error-prone, and
will facilitate parsing patches when relying on a default state, as well as
testing.

Use the explicit default state when parsing mails.

I've found this very informative.  I somehow missed a way to obtain the
default, otherwise.

Excellent, thanks for your work on these. I've committed and pushed, 
plus a couple of minor changes.

Wolfgang - these changes are now live the patchwork.ozlabs.org site too 
now :)

Cheers,

Thanks a lot!

Um... but is it really working?

I added "X-patchwork-state: Accepted" to a reply on a patch; my reply
was correctly added to the respective PW entry
(http://patchwork.ozlabs.org/patch/155545/) but the status did not
change.

Am I doing something wrong?

Best regards,

Wolfgang Denk

You can only request an initial state (e.g. RFC) when submitting the
patch -- in the same mail as the patch.  Changing the state later on by
mail is problematic due to the lack of authentication, I'd say.  But you
can do that with pwclient.

Is is, but:

The patches Dirk sent don't do this; they allow the state to be set on 
the *original mail*, when the patch is first parsed.

The issue with allowing the state to be updated is that there isn't a 
method to authenticate the sender, and ensure that they're a maintainer 
of the project. It's possible to look at the From: field, but that's 
easily faked. In effect, I could send mail to 
incoming@patchwork.ozlabs.org, and set all of the buildroot patches to 
Rejected.

If anyone has useful ideas on how patchwork could do proper 
authentication, then I'd be happy to implement this.

It if suits, you could achieve the same thing with a git hook, which 
sets the patchwork state (using pwclient) when it's applied to your tree.

Cheers,


Jeremy

Oops.   Then I completely misunderstood the purpose of this oatch.

Assinging an _initial_ state seems bogus to me - the initial state is
always "New" - what else shouldit be?  Normally it is not the Submitter
who decides about the processing of the patch.

OK, this leaves 'X-Patchwork-Delegate' which could still be useful.


Of course I can use pwclient - but this is exactly what I want to get
rid of.  I want to have a single user interface to use patchwork - I
do NOT want to have to switch between MUA to reply to a message _and_
use another tool (browser or pwclient) to change the patch state.

I am looking for a way to do this in a _single_ step, using _one_ tool
only.


Regarding security: would it be acceptable if (for example per
repository, or even per user) we could opt to enable such function for
the mail addresses registered as admins?  Yes, it would be trivial to
fake such an address.  But in my case I would be willing to accept
this risk for the added convenience.would it be acceptable if (for

As is, I'm about to give up use of Patchwork because I find the
additional effort to manage the patch states way too high.

I understand thisnow.  Sorry, I was expecting too much :-(

I would be willing to accept this.  I don't expect much misuse here,
and for me the benefit appears to be greater than the risk.

Sorry, but I don't know of an easy _and_ reliable way for email-based
authentication.

I'm using this already, but this is not what I'm looking for.

I want to be able to change the status even without git interaction;
for example, when asking the submitter to rework his patch, I would
like to add a "X-Patchwork-State: Changes Requested" header; when I
see it falls into the bailiwick of a specific custodian, I would also
set the appropriate "X-Patchwork-Delegate" header.

As is, I always have to use a second tool to perform this action -
which means additional efforts, which means patchwork is more of a
pain than a tool that makes my work more efficient.

Actually, that might also be a nice thing for occasional contributors
without an account -- in particular revoking patches (although 
a patch sign language would probably be better in this case, like
[PATCH REVOKED] in the subject).
Anyway, Jeremy, I got the nice automated update notifications this
morning.  Maybe those could be considered sufficient for reassurance?
