Fixed emacs docstrings to be consistent. No functional change.
- removed some (accidental) indentation
- removed some trailing newlines
- added trailing periods where missing (some exclusions)
The features that require field processor support, are now just
documented w/o mentioning **Xapian Field Processors**' is needed
for those.
Replaced "compact" and "field_processor" with "retry_lock" in
build_with config option, as it is currently the only one that
is optionally excluded. The former 2 are now documented as
features always included.
Dropped one 'we' "passive" in notmuch-search-terms.rst. It was the
only one, and inconsistent with rest of the documentation in that
file.
Dropped message about conditional open-ended ranges support, as
those are now always supported.
Also tell users what the consequences of a "No" answer is when
python version is less than 3.5, cffi or setuptools is missing,
or no pytest >= 3.0 is available.
As an initial heuristic, report anyone with at least 15 lines of code
in the current source tree. Test corpora are excluded, although
probabably this doesn't change much about the list of authors
produced.
The sphinx-doc include directive does not have the ability to include
files from the build tree, so we replace the include with reading the
files in conf.py. The non-trivial downside of this is that the emacs
docstrings are now defined for every rst source file. They are
namespaced with docstring::, so hopefully there will not be any
surprises. One thing that is noticable is a small (absolute) time
penalty in running sphinx-doc.
The notmuch2 CFFI-based Python interface is not buildable unless
python3 dev package and python3 setuptools are installed.
Check that these exist in configure (and disable notmuch2 bindings
build if not) so that build of these bindings don't fail when make(1)
is executed.
Before this change, `load-prefer-newer' was ignored.
Set NOERROR and MUST-SUFFIX arguments of `load' to t, and NOSUFFIX
argument to nil, to preserve the behaviour of the deleted `let' form.
This is a simple hack to enable out-of-tree builds, a concern raised
by Tomi in id:m24kzjib9a.fsf@guru.guru-group.fi
This change at least enables "make check" to complete without error,
but I'm sure it could be improved. I am not expert enough in
setuptools to know how.

json_check_nodes.py exists in source tree, not in out of tree
build tree. Added -B to the execution so source tree is not
"polluted" by a .pyc file when json_check_nodes.py is executed.
When creating run_emacs.sh make it load .elc files from out of
tree build tree, not from source tree if such files existed.
If existed, those may be outdated, or even created by some other
emacs than the one that was used to build .elc files in out of
tree build dir.
This change means we can support "notmuch show --decrypt=true" for
S/MIME encrypted messages, resolving several outstanding broken tests,
including all the remaining S/MIME protected header examples.
We do not yet handle indexing the cleartext of S/MIME encrypted
messages, though.

In the two places where _notmuch_crypto_decrypt handles
multipart/encrypted messages (PGP/MIME), we should also handle PKCS#7
envelopedData (S/MIME).
This is insufficient for fully handling S/MIME encrypted data because
_notmuch_crypto_decrypt isn't yet actually invoked for envelopedData
parts, but that will happen in the following changes.

As we prepare to handle S/MIME-encrypted PKCS#7 EnvelopedData (which
is not multipart), we don't want to be limited to passing only
GMimeMultipartEncrypted MIME parts to _notmuch_crypto_decrypt.
There is no functional change here, just a matter of adjusting how we
pass arguments internally.

Until we did PKCS#7 unwrapping, no leaf MIME part could have a child.
Now, we treat the unwrapped MIME part as the child of the PKCS#7
SignedData object. So in that case, we want to show it instead of
deliberately omitting the content.
This fixes the test of the protected subject in
id:smime-onepart-signed@protected-headers.example.

Unwrap a PKCS#7 SignedData part unconditionally when the cli is
traversing the MIME tree, and return it as a "child" of what would
otherwise be a leaf in the tree.
Unfortunately, this also breaks the JSON output. We will fix that
next.

When we are indexing, we should treat SignedData parts the same way
that we treat a multipart object, indexing the wrapped part as a
distinct MIME object.
Unfortunately, this means doing some sort of cryptographic
verification whose results we throw away, because GMime doesn't offer
us any way to unwrap without doing signature verification.
I've opened https://github.com/jstedfast/gmime/issues/67 to request
the capability from GMime but for now, we'll just accept the
additional performance hit.
As we do this indexing, we also apply the "signed" tag, by analogy
with how we handle multipart/signed messages. These days, that kind
of change should probably be done with a property instead, but that's
a different set of changes. This one is just for consistency.
Note that we are currently *only* handling signedData parts, which are
basically clearsigned messages. PKCS#7 parts can also be
envelopedData and authEnvelopedData (which are effectively encryption
layers), and compressedData (which afaict isn't implemented anywhere,
i've never encountered it). We're laying the groundwork for indexing
these other S/MIME types here, but we're only dealing with signedData
for now.

When checking cryptographic signatures, Notmuch relies on GMime to
tell it whether the certificate that signs a message has a valid User
ID or not.
If the User ID is not valid, then notmuch does not report the signer's
User ID to the user. This means that the consumer of notmuch's
cryptographic summary of a message (or of its protected headers) can
be confident in relaying the reported identity to the user.
However, some versions of GMime before 3.2.7 cannot report Certificate
validity for X.509 certificates. This is resolved upstream in GMime
at https://github.com/jstedfast/gmime/pull/90.
We adapt to this by marking tests of reported User IDs for
S/MIME-signed messages as known-broken if GMime is older than 3.2.7
and has not been patched.
If GMime >= 3.2.7 and certificate validity still doesn't work for
X.509 certs, then there has likely been a regression in GMime and we
should fail early, during ./configure.
To break out these specific User ID checks from other checks, i had to
split some tests into two parts, and reuse $output across the two
subtests.

Several functions in test/test-lib.sh used variable names that are
also used outside of those functions (e.g. $output and $expected are
used in many of the test scripts), but they are not expected to
communicate via those variables.
We mark those variables "local" within test-lib.sh so that they do not
get clobbered when used outside test-lib.
We also move the local variable declarations to beginning of each
function, to avoid weird gotchas with local variable declarations as
described in https://tldp.org/LDP/abs/html/localvar.html.

started a thread of discussion that showed that the cli's current
idiosyncrasies around dealing with boolean options were not
understandable.
This attempts to improve the documentation at least (actual changes to
the API might be better, but have not reached consensus).
Note that no one in the discussion thread identified any other
(non-boolean) command-line options that cannot use space as a
separator. If such an option is identified (or introduced in the
future), it should be added explicitly to this part of the manual.

strncmp looks for a prefix that matches, which is very much not what
we want here. This fixes the bug reported by Franz Fellner in
id:1588595993-ner-8.651@TPL520
In id:1588595993-ner-8.651@TPL520 Franz Fellner reported that tags
starting with 'attachment' are removed by 'notmuch reindex'. This is
probably related to the use of STRNCMP_LITERAL in
_notmuch_message_remove_indexed_terms.
GPGME has a strange failure mode when it is in offline mode, and/or
when certificates don't have any CRLs: in particular, it refuses to
accept the validity of any certificate other than a "root" cert.
This can be worked around by setting the `disable-crl-checks`
configuration variable for gpgsm.
I've reported this to the GPGME upstream at
https://dev.gnupg.org/T4883, but I have no idea how it will be
resolved. In the meantime, we'll just work around it.
Note that this fixes the test for verification of
id:smime-multipart-signed@protected-headers.example, because
multipart/signed messages are already handled correctly (one-part
PKCS#7 messages will get fixed later).

Add a simple S/MIME SignedData message, taken from an upcoming draft
of
https://datatracker.ietf.org/doc/draft-autocrypt-lamps-protected-headers/
RFC 8551 describes a SignedData, a one-part clearsigned object that is
more resistant to common patterns of MTA message munging than
multipart/signed (but has the downside that it is only readable by
clients that implement S/MIME).
To make sure sure notmuch can handle this kind of object, we want to
know a few things:
Already working:
- Is the content of the SignedData object indexed? It actually is
right now because of dumb luck -- i think we're indexing the raw
CMS object and it happens to contain the cleartext of the message
in a way that we can consume it before passing it on to Xapian.
- Are we accidentally indexing the embedded PKCS#7 certificates? We
don't want to, and for some reason I don't understand, our indexing
is actually skipping the embedded certificates already. That's
good!
Still need fixing:
- do we know the MIME type of the embedded part?
- do we know that the message is signed?
- can notmuch-show read its content?
- can notmuch-show indicate the signature validity?
- can notmuch-reply properly quote and attribute content?

These sample messages are taken directly from the Protected Headers
draft:

We don't use it yet, but it will be used to decrypt other messages in
the test suite.
Note that we include it here with an empty passphrase, rather than
with the passphrase "bob" that it is supplied with in the I-D. The
underlying cryptographic material is the same, but this way we can
import cleanly into gpgsm without having a passphrase set on it (gpgsm
converts an empty-string passphrase into no passphrase at all on
import).
