Previously we just crashed with an internal error. With this change,
the caller can handle it better. Update notmuch-new so that it doesn't
crash with "unknown error code" because of this change.
In order for a database to actually be writeable, it must be the case that it
is open, not just the correct type of Xapian object. By explicitely
checking, we are able to provide better error reporting, in particular
for the previously broken test in T566-lib-message.
Make the behaviour when passed NULL consistent with
notmuch_filenames_valid. The library already passes the result of
notmuch_message_get_tags without checking for NULL, so it should be
handled.
If we know the configuration is split, but there is no mail root
defined, this indicates a (lack of) configuration error. Currently
this can only arise in XDG configurations.
This is a bit different than n_d_{open,create}_with_config, since
there are several non-zero status codes where we do want to return a
non-NULL database structure.
There are some enum typedefs with the enum name:
typedef enum _name_t { ... } name_t;
We don't need or use the enum names _name_t for anything, and not all
of the enum typedefs have them. We have the typedefs specifically to
use the typedef name.
Use the anonymous enum in the typedefs:
typedef enum { ... } name_t;
Remove the comment markers from the placeholder NOTMUCH_DEPRECATED(),
added in commit e5f3c3ed50 ("lib: add stub for
notmuch_database_open_with_config").
Set the parsing syntax when the (notmuch) query object is
created. Initially the library always returns a trivial query that
matches all messages when using s-expression syntax.
It seems better to select the syntax at query creation time because
the lazy parsing is an implementation detail.
Notmuch 0.32 corresponds to libnotmuch 5.4 as indicated by docstrings;
however, the minor number wasn't bumped. Any libnotmuch downstream
consumer using the LIBNOTMUCH_CHECK_VERSION macro to support multiple
versions won't be able to access the new 5.4 functions.

Both notmuch_database_open() and notmuch_database_open_verbose()'s
documentation state they call notmuch_database_open_with_config() with
config_path=NULL; however, their implementations pass an empty string.
The empty string is the correct value to maintain their original
behavior of not loading the user's configuration so their documentation
is incorrect.
Since the library searches in several locations for a config file, the
caller does not know which of these is chosen in the usual case of
passing NULL as a config file. This changes provides an API for the
caller to retrieve the name of the config file chosen. It will be
tested in a following commit.
The layer of shims here seems a bit wasteful compared to just calling
the corresponding string map functions directly, but it allows control
over the API (calling with notmuch_database_t *) and flexibility for
future changes.
Like the hook directory, we primarily need a way to communicate this
directory between various components, but we may as well let the user
configure it.
Most of the diff is generalizing choose_hook_dir to work for both
backup and hook directories.
Introduce a new configuration value for the mail root, and use it to
locate mail messages in preference to the database.path (which
previously implied the mail messages were also in this location.
Initially only a subset of the CLI is tested in a split
configuration. Further changes will be needed for the remainder of the
CLI to work in split configurations.
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.
