Early blind copy for libc-alpha

Early blind copy for libc-alpha

[Florian Weimer]

Would it be possible to get an early copy of messages sent to
<libc-alpha@sourceware.org> before they go into Mailman?

It will help those of us who apply patches on other people's behalf,
without having to undo the Mailman mangling first.

I would manage bounce processing etc. myself for that alternative
alias, on none-sourceware infrastructure.

The closest thing I can think of is adding a new alias, like
libc-alpha-raw, which expands to libc-alpha and you?

Please also see alternatives outlined in:

Thanks.  No, that's not really useful, sorry.

I guess moving glibc development to a platform that does not have this
problem is something we have to consider at this point.  I do not
think adding even more requirements for contributors is the
appropriate way forward.

What specifically is mailman doing to the email you receive?

The From: header contains the list address, not the patch author,
so feeding the message into “git am” produces an incorrect commit.

I just did a google search for "git am" "dmarc" and see that this pain
point has been around since DMARC started becoming popular.  I didn't
see any solution.  It was interesting to see people like John Levine and
Theorore T'so weighing in on the issue though.

Attached is a simple script which will rewrite the headers so that From:
is no longer munged.  I assume that this could be used as a front-end
for "git am".  This relies on the fact that we have mailman set up to
Cc: the original email sender when the address is munged.

I'm providing this as-is after 15 minutes of work.  There are probably
more elegant ways to accomplish the same task but at least the script is
short.
