These are my own changes, plus those of Florian Klink and Lucas
Hoffmann. Gaute's change fixed a bug that was never in a released
version, so I left it out.
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

test: retrying lock tests are broken when built against older Xapian
If we're building against a version of Xapian that doesn't offer

broken, rather than marking them as missing a test prerequisite.
missing test prerequisites should be for specific components of the
test harness that are missing, not for the backend library notmuch

Named queries don't work without Xapian FieldProcessor. Rather than
silently skipping them, we should explictly mark them as broken when

test: searching by absolute date is broken without Xapian FieldProcessor
Previously, the test suite had simply silently skipped the absolute
date test if we're using an archaic version of Xapian. For

For boolean arguments this obviously means the logical NOT. For
keyword flag arguments this means bitwise AND of the bitwise NOT,
i.e. masking out the specified bits instead of OR'ing them in.
For example, you can use --no-exclude instead of --exclude=false in
notmuch show. If we had keyword flag arguments with some flags
defaulting to on, say --include=tags in notmuch dump/restore, this
would allow --no-include=tags to switch that off while not affecting
other flags.
As a curiosity, you should be able to warp your brain using
--no-exclude=true meaning false and --no-exclude=false meaning true if
you wish.
Specifying both "argument" and "no-argument" style arguments in the
same option description should be avoided. In this case, --no-argument
would match whichever is specified first, and --argument would only
match "argument".

crypto: signature verification reports valid User IDs
When i'm trying to understand a message signature, i care that i know
who it came from (the "validity" of the identity associated with the
key), *not* whether i'm willing to accept the keyholder's other
identity assertions (the "trust" associated with the certificate).
We've been reporting User ID information based on the "trust"
associated with the certificate, because GMime didn't clearly expose
the validity of the User IDs.

include https://github.com/jstedfast/gmime/pull/18.
docs: clean up documentation about decryption policies
Now that the range of sensible decryption policies has come into full
view, we take a bit of space to document the distinctions.
Most people will use either "auto" or "true" -- but we provide "false"
and "nostash" to handle use cases that might reasonably be requested.
Note also that these can be combined in sensible ways. Like, if your
mail comes in regularly to a service that doesn't have access to your
secret keys, but does have access to your index, and you feel
comfortable adding selected encrypted messages to the index after
you've read them, you could stay in "auto" normally, and then when you
find yourself reading an indexable message (e.g. one you want to be
able to search for in the future, and that you don't mind exposing to
whatever entities have access to your inde), you can do:
crypto: add --decrypt=nostash to avoid stashing session keys
Here's the configuration choice for people who want a cleartext index,
but don't want stashed session keys.
Interestingly, this "nostash" decryption policy is actually the same
policy that should be used by "notmuch show" and "notmuch reply",
since they never modify the index or database when they are invoked
with --decrypt.
We take advantage of this parallel to tune the behavior of those
programs so that we're not requesting session keys from GnuPG during
"show" and "reply" that we would then otherwise just throw away.
crypto: actually stash session keys when decrypt=true
If you're going to store the cleartext index of an encrypted message,
in most situations you might just as well store the session key.
Doing this storage has efficiency and recoverability advantages.
Combined with a schedule of regular OpenPGP subkey rotation and
destruction, this can also offer security benefits, like "deletable
e-mail", which is the store-and-forward analog to "forward secrecy".
But wait, i hear you saying, i have a special need to store cleartext
indexes but it's really bad for me to store session keys! Maybe
(let's imagine) i get lots of e-mails with incriminating photos
attached, and i want to be able to search for them by the text in the
e-mail, but i don't want someone with access to the index to be
actually able to see the photos themselves.
Fret not, the next patch in this series will support your wacky
uncommon use case.
cli/reindex: destroy stashed session keys when --decrypt=false
There are some situations where the user wants to get rid of the
cleartext index of a message. For example, if they're indexing
encrypted messages normally, but suddenly they run across a message
that they really don't want any trace of in their index.
But of course, clearing the cleartext index without clearing the
stashed session key is just silly. So we do the expected thing and
also destroy any stashed session keys while we're destroying the index
of the cleartext.
Note that stashed session keys are stored in the xapian database, but
xapian does not currently allow safe deletion (see
https://trac.xapian.org/ticket/742).
As a workaround, after removing session keys and cleartext material
from the database, the user probably should do something like "notmuch
compact" to try to purge whatever recoverable data is left in the
xapian freelist. This problem really needs to be addressed within
xapian, though, if we want it fixed right.
cli/new, insert, reindex: change index.decrypt to "auto" by default
The new "auto" decryption policy is not only good for "notmuch show"
and "notmuch reindex". It's also useful for indexing messages --
there's no good reason to not try to go ahead and index the cleartext
of a message that we have a stashed session key for.
This change updates the defaults and tunes the test suite to make sure
that they have taken effect.
crypto: record whether an actual decryption attempt happened
In our consolidation of _notmuch_crypto_decrypt, the callers lost
track a little bit of whether any actual decryption was attempted.
Now that we have the more-subtle "auto" policy, it's possible that
_notmuch_crypto_decrypt could be called without having any actual
decryption take place.
This change lets the callers be a little bit smarter about whether or
not any decryption was actually attempted.
cli/show, reply: document use of stashed session keys in notmuch-properties
The stashed session keys are stored internally as notmuch properties.
So a user or developer who is reading about those properties might
want to understand how they fit into the bigger picture.
Note here that decrypting with a stored session key no longer needs
-decrypt for "notmuch show" and "notmuch reply".
cli/show: use decryption policy "auto" by default.
When showing a message, if the user doesn't specify --decrypt= at all,
but a stashed session key is known to notmuch, notmuch should just go
ahead and try to decrypt the message with the session key (without
bothering the user for access to their asymmetric secret key).
The user can disable this at the command line with --decrypt=false if
they really don't want to look at the e-mail that they've asked
notmuch to show them.
and of course, "notmuch show --decrypt" still works for accessing the
user's secret keys if necessary.
cli/reply: use decryption policy "auto" by default.
If the user doesn't specify --decrypt= at all, but a stashed session
key is known to notmuch, when replying to an encrypted message,
notmuch should just go ahead and decrypt.
The user can disable this at the command line with --decrypt=false,
though it's not clear why they would ever want to do that.
This new automatic decryption policy should make it possible to
decrypt messages that we have stashed session keys for, without
incurring a call to the user's asymmetric keys.
the command-line interface for indexing (reindex, new, insert) used
--try-decrypt; and the configuration records used index.try_decrypt.
But by comparison with "show" and "reply", there doesn't seem to be
any reason for the "try" prefix.
This changeset adjusts the command-line interface and the
configuration interface.
For the moment, i've left indexopts_{set,get}_try_decrypt alone. The
subsequent changeset will address those.
