The extra flexibility of having both HAVE_EMACS (for yes, there is an
emacs we can use) and WITH_EMACS (the user wants emacs support) lead
to confusion and bugs. We now just force WITH_EMACS to 0 if no
suitable emacs is detected.
This way if variables defined using unused() macro are actually
used then code will not compile...
- removed unused usage around one argc and one argv since those
were used
- changed one unused (char *argv[]) to unused (char **argv) to
work with modified unused() macro definition
Without this change, dh_gencontrol emits:
dpkg-gencontrol: warning: package python-notmuch: substitution variable ${python:Provides} unused, but is defined

Debian's build hardening toolchain options produce binary artifacts
that are more resistant to compromise. The most visible change for
notmuch today is likely to be the addition of the "bindnow" linker
flag, which contributes to making the "Global Offset Table" fully
read-only.

Dropped unnecessary empty string check when reading results files.
Replaced pluralize() which was executed in subshell with
pluralize_s(). pluralize_s sets $s to 's' or '' based on value of
$1. Calls to pluralize_s are done in context of current shell, so
no forks to subshells executed.
In 40b025 we stopped building the notmuch-emacs documentation if
HAVE_EMACS=0 (i.e. no emacs was detected by configure). Unfortunately
we continued to try to install the (non-existent) documentation, which
causes build/install failures.
As a bonus, we also avoid installing the documentation if the user
configures --without-emacs.
Thanks to Ralph Seichter for reporting the problem, and testing
previous versions of this fix.
Since the docstrings are not built in the case of --without-emacs,
even if emacs is detected, don't let sphinx build the emacs docs. This
avoids a large number of error messages due to missing includes. It's
actually a bit surprising sphinx doesn't generate an error for the
missing include files.
When the user knows the signer's key, we want "notmuch show" to be
able to verify the signature of an encrypted and signed message
regardless of whether we are using a stashed session key or not.
I wrote this test because I was surprised to see signature
verification failing when viewing some encrypted messages after
upgrading to GPGME 1.13.0-1 in debian experimental.
The added tests here all pass with GPGME 1.12.0, but the final test
fails with 1.13.0, due to some buggy updates to GPGME upstream: see
https://dev.gnupg.org/T3464 for more details.
While the bug needs to be fixed in GPGME, notmuch's test suite needs
to make sure that GMime is doing what we expect it to do; i was a bit
surprised that it hadn't caught the problem, hence this patch.
I've fixed this bug in debian experimental with gpgme 1.13.0-2, so the
tests should pass on any debian system. I've also fixed it in the
gpgme packages (1.13.0-2~ppa1) in the ubuntu xenial PPA
(ppa:notmuch/notmuch) that notmuch uses for Travis CI.

Previous version expected full upstream install to be run, and also

It seems our previous attempt with order-only targets was not
sufficient to avoid problems with sphinx-builds doctree cache [0].
Looking around at other people's approaches [1], using separate
doctrees was suggested. I guess there might be a slight loss of
efficiency, but it seems more robust.

Part 0 of a multipart/encrypted object is
GMIME_MULTIPART_ENCRYPTED_VERSION; part 1 is
GMIME_MULTIPART_ENCRYPTED_CONTENT. Using the name for what we want
describes our intent more clearly than using a magic number in the
code.

Protected subject lines were being emitted in reply when the cleartext
of documents was indexed. create_reply_message() was pulling the
subject line from the index, rather than pulling it from the
GMimeMessage object that it already has on hand.
This one-line fix to notmuch-reply.c solves that problem, and doesn't
cause any additional tests to fail.

These tests are currently broken! When a protected subject is indexed
in the clear, it leaks in the reply headers :(
For emacs, we set up separate tests for when the protected header is
indexed in the clear and when it is unindexed. neither case should
leak, but the former wasn't tested yet.
We will fix the two broken tests in a subsequent patch.

Up to this point, we've tested protected headers on messages that have
either been encrypted or signed, but not both.
This adds a couple tests of signed+encrypted messages, one where the
subject line is masked (outside subject line is "Subject Unavailable")
and another where it is not (outside Subject: matches inner Subject:)

Now that we can decrypt headers, we want to make sure that clients
using "notmuch reply" to prepare a reply don't leak cleartext in their
subject lines. In particular, the ["reply-headers"]["Subject"] should
by default show the external Subject.
A replying MUA that intends to protect the Subject line should show
the user the Subject from ["original"]["headers"]["Subject"] instead
of using ["reply-headers"]["Subject"].
This minor asymmetry with "notmuch show" is intentional. While both
tools always render the cleartext subject line when they know it (in
["headers"]["Subject"] for "notmuch show" and in
["original"]["headers"]["Subject"] for "notmuch reply"), "notmuch
reply" should never leak something that should stay under encrypted
cover in "reply-headers".

Signed-off-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>
The header-mask member of the per-message crypto object allows a
clever UI frontend to mark whether a header was protected (or not).
And if it was protected, it contains enough information to show useful
detail to an interested user. For example, an MUA could offer a "show
what this message's Subject looked like on the wire" feature in expert
mode.
As before, we only handle Subject for now, but we might be able to
handle other headers in the future.

When walking the MIME tree, if we discover that we are at the
cryptographic payload, then we would like to record at least the
Subject header of the current MIME part.
In the future, we might want to record many other headers as well, but
for now we will stick with just the Subject.
