I can amend it if you agree. I don't think i understand your suggestion. that value *is* used, by the "(when show-button …)" construct later in the code. The idea was to make the button shown by default, unless it was disabled further down in the patch (in the "t" clause of the main "cond" construct in notmuch-crypto-insert-sigstatus-button, which only triggers if we legitimately don't have any status information (if "status" is nil)). So no, i think it's supposed to start off "t" and then get disabled in the specific condition this patch tests for. If i've misunderstood the e-lisp (entirely possible!) i would be happy to be corrected. --dkg signature.asc Description: PGP signature ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch

I haven't heard any public complaints about this proposed change, and it is a concrete improvement to the usability of encrypted-but-unsigned messages.

I've heard from some people that they don't like this final patch because the "[ Unknown signature status ]" button is at least an indication that the message appears to be signed (even if we decided not to -- or were unable to -- evaluate the signature). I considered argument this when writing the patch initially, and i don't think it's a good argument for two reasons: a) without actual signature verification, the user experience is trivially scammable by an adversary who knows how to craft a MIME message, and it's basically encouraging a user pattern that is something along the lines of: https://xkcd.com/1181/ (though maybe a bit more subtle, based on MIME structure instead of the inline-signing that xkcd is mocking) This is a particularly bad security indicator and user experience. The thing isn't reliable, and it's not actionable in most cases. b) In the current state of the codebase, the presence of the button does *not* indicate that a signature-like thing is even present. If you look at test/emacs-show.expected-output/notmuch-show-decrypted-message, that shows the cleartext view of a decrypted message which *does not* have an OpenPGP signature on it at all (test/corpora/crypto/basic-encrypted.eml is encrypted but unsigned). I could imagine changing notmuch to fix concern (b) -- that is, hiding the button just in the case where no signature-looking thing is present at all. But i haven't seen anyone even identify that problem publicly yet, let alone offer a fix for it. But i think that (a) is at least as big of a concern as (b); the fix i'm proposing in this series is actually simpler than such a targeted fix would be; and the fix in this series actually solves both problems. If someone wants to offer a fix just for (b) on top of the first two patches in this series, i'd happily advocate for it as better than the status quo, which would let us put off (a) to a more interesting and targeted discussion. --dkg signature.asc Description: PGP signature ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
Re: [PATCH 3/3] emacs: Drop content-free "Unknown signature status" button
The first two patches in this series should be uncontroversial (they're just establishing a baseline), and i'd appreciate it if they could be considered for merging regardless of whether anyone raises an objection to this last patch of the series.

This is a small step down the path of making notmuch-emacs friendlier with regards to encrypted messages, but it's one that will have an effect on future patch series that work with encrypted messages. I'd be happy to hear any concerns people have about this change, but i find notmuch-emacs is more pleasant to use this way. --dkg signature.asc Description: PGP signature ___ notmuch mailing list notmuch@notmuchmail.org https://notmuchmail.org/mailman/listinfo/notmuch
