In the future Xapian will apparently support this more conveniently
for the cases other than READ_ONLY => READ_ONLY
Conceptually this function seems to fit better in lib/open.cc;
database.cc is still large enough that moving the function makes
sense.
Include the (currently unused) mode argument which will specify which
mode to re-open the database in. Functionality and docs to be
finalized in a followup commit.
The hook directory configuration needs to be kept in synch with the
other configuration information, so add scaffolding to support this at
database opening time.
This will allow client code to provide more meaningful diagnostics. In
particular it will enable "notmuch new" to continue suggsting the user
run "notmuch setup" to create a config after "notmuch new" is
transitioned to the new configuration framework.
By using an enum we can have better error detection than copy pasting
key strings around.
The question of what layer this belongs in is a bit
tricky. Historically most of the keys are defined by the CLI. On the
other hand features like excludes are supported in the
library/bindings, and it makes sense to configure them from the
library as well.
The somewhat long prefix for notmuch_config_t is to avoid collisions
with the existing usage in notmuch-client.h.
It's not very nice to return FALSE for an error, so provide
notmuch_message_get_flag_st as a migration path.
Bump LIBNOTMUCH_MINOR_VERSION because the API is extended.
Apparently doxygen needs its comments formatted in a specific way to
notice that the group is closed.
Without this fix, with doxygen 1.8.16-2 we see:
```
doxygen ./doc/doxygen.cfg
…/notmuch/lib/notmuch.h:2322: warning: end of file while inside a group
```

This is technically an API change, but it is not an ABI change, and
it's merely a statement that limits what the library can do.
This is in parallel to notmuch_query_get_database(), which also takes
a const pointer.
The user can already do this manually, of course, but (a) it's nice to
have a convenience function, and (b) exposing this interface means
that someone more clever with a _notmuch_string_map_t than i am can
write a more efficient version if they like, and it will just
accelerate the users of the convenience function.
We've had _notmuch_message_database() internally for a while, and it's
useful. It turns out to be useful on the other side of the library
interface as well (i'll use it later in this series for "notmuch
show"), so we expose it publicly now.
We added several new functions, at least
notmuch_database_get_default_indexopts
notmuch_database_index_file
notmuch_indexopts_destroy
notmuch_indexopts_get_decrypt_policy
notmuch_indexopts_set_decrypt_policy
notmuch_message_count_files
notmuch_message_has_maildir_flag
notmuch_message_reindex
notmuch_message_remove_all_properties_with_prefix
notmuch_thread_get_total_files
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.
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.
Future patches in this series will introduce new policies; this merely
readies the way for them.
We also convert --try-decrypt to a keyword argument instead of a boolean.
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).
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.
