Based on the method outlined by Daniel Kahn Gillmor in
id:87k1zm225v.fsf@fifthhorseman.net. With a delay of 0.2 seconds the
test becomes flaky on my machine. With a 1 second delay it fails
consistently for more than 1600 iterations.
When the certificate that signs a message is known to be valid, GMime
is capable of reporting on the e-mail address embedded in the
certificate.
We pass this information along to the caller of "notmuch show", as
often only the e-mail address of the certificate has actually been
checked/verified.
Furthermore, signature verification should probably at some point
compare the e-mail address of the caller against the sender address of
the message itself. Having to parse what gmime thinks is a "userid"
to extract an e-mail address seems clunky and unnecessary if gmime
already thinks it knows what the e-mail address is.
See id:878s41ax6t.fsf@fifthhorseman.net for more motivation and discussion.

Sourcing test-lib.sh will cd to TMP_DIRECTORY, so
relative path in $0 will not work in previous version
. $(dirname "$0")/test-lib-emacs.sh
Now individual test scripts -- e.g. ./test/T310-emacs.sh
will work.
This allows MUAs that don't want to think about per-mime-part
cryptographic status to have a simple high-level overview of the
message's cryptographic state.
Sensibly structured encrypted and/or signed messages will work fine
with this. The only requirement for the simplest encryption + signing
is that the message have all of its encryption and signing protection
(the "cryptographic envelope") in a contiguous set of MIME layers at
the very outside of the message itself.
This is because messages with some subparts signed or encrypted, but
with other subparts with no cryptographic protection is very difficult
to reason about, and even harder for the user to make sense of or work
with.
For further characterization of the Cryptographic Envelope and some of
the usability tradeoffs, see here:

The typical use case for gpg is that if you control a secret key, you
mark it with "ultimate" ownertrust.
The opaque --import-ownertrust mechanism is GnuPG's standard mechanism
to set up ultimate ownertrust (the ":6:" means "ultimate", for
whatever reason).
We adjust the test suite to match this change, inverting the sense of
one test: since the default is now that the user ID of the suite's own
key is valid, we change the test to make sure that the user ID is not
emitted when it is *not* valid.

The user ID on the self-test is a little bit clunky-looking. It also
may end up showing up elsewhere in the test suite. Centralizing the
user ID in one place should make it easier to handle if it ever
changes, and should make tests easier to read.

This is a subtle difference, but the output of notmuch shouldn't ever
change based on ownertrust itself -- notmuch is intended to show valid
User IDs, and to avoid showing invalid User IDs.
It so happens that setting ownertrust of a key to ultimate sets all
associated user IDs to "full" validity, so the test is correct, but
just misnamed.

note that "notmuch-show for message with invalid From" is still broken
in T310-emacs.sh. It would be good to debug what's going on there and
try to get it fixed!

Unsigned encrypted mail shows up with a weird empty signature list.
If we successfully decrypted and there was no signature in it, we
should just not show a sigstatus at all.
The documentation for g_mime_decrypt_result_get_signatures says:
a GMimeSignatureList or NULL if the stream was not signed.
If a test has added a GnuPG homedir, it may well want to know the
fingerprint. This saves us from having to redefine this magic string
in multiple places when more tests eventually use the GnuPG homedir.
When generating a reply message, if the user was the originator and
only recipient of the original message, include the user as a
recipient of the reply.
This brings the --decrypt argument to "notmuch reply" into line with
the other --decrypt arguments (in "show", "new", "insert", and
"reindex"). This patch is really just about bringing consistency to
the user interface.
We also use the recommended form in the emacs MUA when replying, and
update test T350 to match.
We also expand tab completion for it, update the emacs bindings, and
update T350, T357, and T450 to match.
Make use of the bool-to-keyword backward-compatibility feature.
This is a logical followup to "lib: index the content type of
signature parts", which will make it easier to record the message
structure of all messages.
It's useful (*) to be able to easily find messages with certain types
of signatures. Having the mimetype: prefix searches fail for some
content types is also genuinely surprising (*). Index the content type
of signature parts.
While at it, switch to the gmime convenience constants for content and
signature part indexes.
*) At least for developers of email software!
Add known broken subtests for searching signed and encrypted messages
using mimetype: prefix search for the content-types of signed and
encrypted parts.
In [1], Vladimir Panteleev observed that the In-Reply-To and
References headers could be wrapped in the 'default' output format of
notmuch-reply, depending on the version of Emacs creating the
message. In my own experiments notmuch-reply sometimes wraps headers
with only one message-id if that message-id is long enough. However it
happens, this causes the previous approach using grep to fail.
Since I found the proposed unwrapping shell fragment in [1] a bit hard
to follow, I decided to write a little python script instead. Then
Tomi suggested a slight generalization of my script, and here we are.

Since the error field is unused by the emacs front end, no changes are
needed other than bumping the format version number.
As it is, this is a bit overengineered, but it will reduce duplication
when we support gmime 3.0
Since gnupg 2.1.20, gpg-agent no longer shut itself down when
$GNUPGHOME directory is removed.
Add exit hooks to the test modules which execute `gpgconf --kill all`
Add exit hooks to execute `gpgconf --kill all` in the modules that
create $GNUPGHOME for gpg to work with.
Unify the subtests by requiring test_begin_subtest before
test_expect_success. (Similar change for test_expect_code will
follow.)
This increases clarity in the test scripts by having a separate line
for the start of the subtest with the heading, and makes it possible
to simplify the test infrastructure by making all subtests similar.
Instead of just having the first filename for the message, list all
duplicate filenames of the message as a list in the formatted
outputs. This bumps the format version to 3.
GnuPG 2.1.16 is now injecting the full issuer fingerprint in its
signatures, which makes them about 32 octets larger when
ascii-armored.
This change in size means that the size of the MIME parts will vary
depending on the version of gpg that the user has installed. at any
rate, the signature part should be non-zero (this is true for
basically any MIME part), so we just test for that instead of an exact
size.
This stops the (usually incorrect) sigstatus and encstatus buttons
appearing when replying in emacs, and updates the test suite to match.
Overriding the status button functions is a little unusual but much
less intrusive than passing an argument all the way down the call
chain. It also makes it clear exactly what it does.
We also hide the application/pgp-encrypted part as it can only contain
"Version: 1". We do this in notmuch show, which means it also happens
when replying.
Originally the intent was to make the test more robust against changing
test keys. It turns out that (unscientifically) gpg --with-colons output
changes more often than our test key. Rather than making the script more
complex, just hard code the fingerprint.
This fixes Debian bug #847013; I expect similar test failures as other
distros adopt gnupg 2.1.15
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
