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.
