I wrote this test because I was surprised to see signature

8 weeks agotest/emacs: revert invalid-from test to pre-86f89385 behaviour

test/emacs: revert invalid-from test to pre-86f89385 behaviour

To the best of my understanding, this original behaviour was what
Carl's homebrew parser produced. With commit 86f89385 Austin switched
to using GMime (2.6). This produced arguably worse results, but since
the input was bad, we could live with it. Now with GMime 3.0 we are
getting the original results again, and there is no reason to consider
this test broken.

8 weeks agoconfigure: Ensure that GMime can extract session keys
Daniel Kahn Gillmor [Mon, 6 May 2019 20:16:55 +0000 (16:16 -0400)]
configure: Ensure that GMime can extract session keys

GMime 3.0 and higher can extract session keys, but it will *not*
extract session keys if it was built with --disable-crypto, or if it
was built against GPGME version < 1.8.0.

Notmuch currently expects to be able to extract session keys, and
tests will fail if it is not possible, so we ensure that this is the
case during ./configure time.

Part of this feels awkward because notmuch doesn't directly depend on
gpg at all.  Rather, it depends on GMime, and the current
implementation of GMime depends on GPGME for its crypto, and GPGME in
turn depends on gpg.

So the use of gpg in ./configure isn't actually introducing a new
dependency, though if a future version of GMime were ever to move away
from GnuPG, we might need to reconsider.

Note that this changeset depends on
id:20190506174327.13457-1-dkg@fifthhorseman.net , which supplies the
rfc822 message test/corpora/crypto/basic-encrypted.eml used in it.

8 weeks agotests: make timeout configurable with NOTMUCH_TEST_TIMEOUT (default: 2m)

tests: make timeout configurable with NOTMUCH_TEST_TIMEOUT (default: 2m)

The current 2 minute timeout is reasonable, but to exercise the test
suite or induce timeout failures, we might want to make it shorter.
This makes it configurable so you can run (for example):

    make check NOTMUCH_TEST_TIMEOUT=10s

We stick with the default of 2m.
