Commit 1fdc08d0ff ("cli/crypto: treat failure to create a crypto
context as fatal.") started treating crypto context creation failures
"as fatal", returning NULL from _mime_node_create().
Unfortunately, we do not have NULL checks for _mime_node_create()
failures. The only caller, mime_node_child(), could check and return
NULL (as it's documented to do on errors) but none of the several call
sites have NULL checks either. And none of them really have a trivial
but feasible and graceful way of recovery.
So while the right thing to do would be to handle NULL returns
properly all over the place, and we have other scenarios that do
return NULL from above mentioned functions, the crypto context
creation failure is something that does seem to show up regularly in
some scenarios, revert back to the functionality before commit
1fdc08d0ff as an interim fix.
backup_database() and restore_database() used to store the backups in
the test specific temporary directory, through the current working
directory being there. Commit 8e7fb88237 ("test: use source and
build paths in test-lib-common.sh") started using a test specific
backup directories under the build tree test directory. This was in
error. Switch back to the old location, but using paths to the
location instead of relying on current working directory.

Enable override of the index.try_decrypt setting on a per-run basis
when invoking "notmuch reindex". This allows the possibility of (for
example) an emacs keybinding that adds the cleartext of the currently
shown decrypted message to the index, making it searchable in the
future.
It also enables one-time indexing of all messages matching some query,
like so:
notmuch reindex tag:encrypted and\
not property:index.decryption=success and\
from:alice@example.org
We also update the documentation and tab completion, and add a few
more tests.
Enable override of the index.try_decrypt setting on a per-message
basis when invoking "notmuch insert".
We also update the documentation and tab completion, and add more tests.
Enable override of the index.try_decrypt setting during "notmuch new"
on a per-invocation basis.
We update the documentation and tab completion, and also add a test.
Subsequent patches may want to send GNU-style --long-arguments to
notmuch new in the test suite, in particular when invoking
emacs_fcc_message. This changeset makes that possible.
We have an indexopts structure for manipulating indexing in different
ways, but we also have three command-line invocations that can trigger
indexing: new, insert, and reindex.
This changeset prepares a common parser that these subcommands can
share.
Note: if the deprecated crypto.gpg_path configuration option is set to
anything other than "gpg", we ignore it (and print a warning on
stderr, if built against gmime < 3.0).
At the moment, it's just --try-decrypt, but others will likely follow.
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.
