Acked-by missed when applying

[Lee Jones]

Good morning Konstantin,

Can you think of a reason why `b4` missed Greg's Ack here?

Because you applied the first v2 patch, not the second v2 threaded to
the 1st one that Greg acked.

Should we issue a warning in such cases? E.g:

WARNING: Identically numbered patches found, will use the latest by date.
         Download and edit the mailbox manually for any other outcome.

Please!  In general the messages b4 prints when it resolves any
ambiguity are really helpful.

+1.  If b4 could give us the message id's and message time stamps,
that would be great.  Even better, perhaps b4 could download both, and
diff the two patches, which might give us some clue if it was just the
same patch accidentally sent twice, or change in the commit
description (maybe the sender forgot to add some trailers?), or the
commit diffs are actually different, in which case maybe the sender
forgot to increment the version number.

Not sure I understand.

This is the thread of the patch I merged:

https://i.imgur.com/k4hD9kO.png

Greg's Ack is located in the 5th message down.

If you look at the thread overview, you'll notice that there are two messages
with identical subjects, sent 3 weeks apart:

2021-09-02 12:47 [PATCH v2] mfd: hi6421-spmi-pmic: cleanup drvdata

and

2021-09-28  6:58 [PATCH v2] mfd: hi6421-spmi-pmic: cleanup drvdata

As far as b4 is treating things internally, the second v2 (from Sep 28)
starts a new thread, so any trailers sent to the Sep-02 version will not
apply to the Sep-29 version and vice versa.

Oh I see.

That's not obvious from Mutt or LORE:

Thanks Rob, Konstantin for the explanation.

The patch is actually identical (and I guess it is also identical
to version 1). I ended forgetting that I had already submitted it during
the merge window. So, I ended forgetting to either increase its version
number or to add a RESEND to it.

Sorry for the mess.

If it wasn't you, it would have been someone else.

Thanks for highlighting issue.

Hopefully it can be resolved trivially.
