By default, notmuch won't try to decrypt on indexing. With this
patch, we make it possible to indicate a per-database preference using
the config variable "index.try_decrypt", which by default will be
false.
At indexing time, the database needs some way to know its internal
defaults for how to index encrypted parts. It shouldn't be contingent
on an external config file (since that can't be retrieved from the
database object itself), so we store it in the database.
This behaves similarly to the query.* configurations, which are also
stored in the database itself, so we're not introducing any new
dependencies by requiring that it be stored in the database.
QUERY_STRING was only used in two places, both to test whether a
variable should be stored in (or retrieved from) the database.
Since other configuration variables might be stored in the database in
the future, consolidate that test into a single function.
We also document that these configuration options should not be placed
in the config file.
If we see index options that ask us to decrypt when indexing a
message, and we encounter an encrypted part, we'll try to descend into
it.
If we can decrypt, we add the property index.decryption=success.
If we can't decrypt (or recognize the encrypted type of mail), we add
the property index.decryption=failure.
Note that a single message may have both values of the
"index.decryption" property: "success" and "failure". For example,
consider a message that includes multiple layers of encryption. If we
manage to decrypt the outer layer ("index.decryption=success"), but
fail on the inner layer ("index.decryption=failure").
Because of the property name, this will be automatically cleared (and
possibly re-set) during re-indexing. This means it will subsequently
correspond to the actual semantics of the stored index.
This allows us to create new properties that will be automatically set
during indexing, and cleared during re-indexing, just by choice of
property name.
This is currently mostly a wrapper around _notmuch_crypto_t that keeps
its internals private and doesn't expose any of the GMime API.
However, non-crypto indexing options might also be added later
(e.g. filters or other transformations).
The primary motivation here is to fix TMP_DIRECTORY cleanup prior to
running each test when the current working directory is not the test
subdirectory. Tests with failures would leave their TMP_DIRECTORY
directory behind for debugging, and repeated out-of-tree test runs
would have old temp directories. (This lead to e.g. T310-emacs.sh
hanging because emacs would prompt for overwriting files.)
We remove the likely anyway defunct --root test option while at it,
just to be on the safe side when doing 'rm -rf' on the TMP_DIRECTORY.
Turns out round trip tests didn't really round trip anything. Broken
by yours truly in 971cdc72cd ("test: make it possible to have
multiple corpora"). Ooops.
Subsequent patches will introduce a convention that properties whose
name starts with "index." will be stripped (and possibly re-added)
during re-indexing. This patch lays the groundwork for doing that.
Commit 0f314c0c99 ("cli: convert notmuch_bool_t to stdbool")
over-eagerly converted EXCLUDE_TRUE and EXCLUDE_FALSE to EXCLUDE_true
and EXCLUDE_false in notmuch-count.c. We could just fix the case back,
but convert the option to an actual boolean argument instead.
We've used a keyword argument rather than a boolean argument for
notmuch count --exclude for five years, since commit 785c1e497f
("cli: move count to the new --exclude=(true|false|flag) naming
scheme."), "to allow future options to be added more easily". I think
we can conclude future options aren't coming any time soon.
In practice, we're going to see this function invoked differently
depending on which gmime we build against. The compatibility layer
forces our code into the lowest-common-denominator -- unable to make
use of new features even when built against a newer version.
Dropping the compatibility layer paves the way for clearer use of
features from GMime 3.0 in future commits.
"typedef GMimeAddressType GMimeRecipientType" is already present
further down in the compatibility wrapper (with other typedefs). We
don't need it twice.
There's no chance that _notmuch_crypto_cleanup() will ever return
anything other than 0, and no one ever checks its return value anyway.
So make it return void instead of int.
notmuch_crypto_context_t was introduced (i think) as some sort of
abstraction layer to make notmuch somewhat independent of GMime. But
it isn't even useful for GMime 3.0 or later -- we can drop the
pretense that it's some sort of abstraction in this case, and just
call it what it is, GMimeCryptoContext, which is useful for building
against older versions of GMime.
This also renames _notmuch_crypto_get_context() to
_notmuch_crypto_get_gmime_context().
The notmuch_crypto_t struct isn't used externally, and we have no
plans to explicitly export it. Prefix its name (and associated
functions) with _ to make that intent clear.
C99 stdbool turned 18 this year. There really is no reason to use our
own, except in the library interface for backward
compatibility. Convert the lib internally to stdbool.

Renamed from out-of-tree-build-check.sh to be consistent with
other files in this directory.
Fixed quoting in "$srcdir" usage for additional robustness, other
quoting changes for consistency.
