Hello:

I'm working away on grokmirror+public-inbox replication, and I'm trying to
come up with a good solution for passing the "archiver origins" info. In
examples/grok-pull.post_update_hook.sh, we try to get this information out of
a curl call to the clone origin, but this may not be reliable for a number of
reasons:

1. we may be cloning from an intermediary location that only serves the git
   repositories and the manifest file (e.g. erol.kernel.org)
2. the call may retrieve information relevant to the intermediary, and not to
   the origins of the archive

I'm thinking of including a special location in the git repo itself for
passing some of the same info currently found in the config snippet, e.g. in
refs/meta/origins.

Imaginary code snippet:

$ git show refs/meta/origins:i
[metadata]
source = smtp
listaddress = linux-kernel@vger.kernel.org
listid = linux-kernel.vger.kernel.org
archive-url = https://lore.kernel.org/linux-kernel
archive-contact = postmaster@kernel.org

This way, even if the archive gets mirrored around a bunch of times, it's
still possible to track where it originated, and if the original archive info
becomes obsolete, someone can update the information without it affecting the
rest of the archive.

Does that sound sane?

Is "source" necessary?  It seems like something that could be
in the "description" file or noted in the contents of
publicinbox.$NAME.infourl.

I think the keys should match what we use in the config file, at
least.  So s/listaddress/address/ and s/archive-url/url/

I'm not sure if "contact" is necessary if the aforementioned
"infourl" exists.

I think so.  Only the latest epoch would be taken into account,
I suppose.

I wasn't sure what infourl was used for. :) Is it supposed to contain
structured data, or is it more of a "click here for more info" kind of thing?

Okay.

My thinking is that with mirrors of mirrors of mirrors, if someone submits a
GDPR removal request, then there should be an easy way of figuring out where
these requests should actually go. Maybe infourl can cover this, but it's less
likely to be set up than an email address like postmaster@. So, I'm in favour
of keeping that in the info record.

I'm actually thinking the other way around -- only the 0.git (or whatever is
the lowest number), simply because it's more likely to have that record. That
is, unless you want to add functionality to automatically copy these from
previous epochs on auto-rotation events.

Bugs are crazy invasive, again :<

It's "click here for more info", so freeform.  It should
probably be added to the footer of every HTML page.

I'm a little worried about it having too many directions
(e.g. webmaster vs postmaster) and something freeform like
infourl can cover it.  Or we maybe something with user-defined
labels would work:

	contact = postmaster mail-admin@example.com
	contact = GPDR https://our-lawyers.example.com/form.cgi
	contact = webmaster web-admin@example.com

It should be easy to change this info down-the-line in case of
project name/hosting changes, forks, etc.  So whatever's latest
should supercede the older.  It would also allow partial mirrors
to work with only the latest epoch(s) (I expect a partial
mirrors of recent epochs to be more useful than mirrors with
only old epochs).

Maybe more RFC2822-like:

 	contact = postmaster <mail-admin@example.com>
 	contact = GPDR <https://our-lawyers.example.com/form.cgi>
 	contact = webmaster <web-admin@example.com>

Should be kosher with git-config and a bit more obvious that one is a label.

OK, I'm not picky and it's easy to reverse the dir listing.

I'll trial it out on some lore archives and then share the resulting hooks.
