Use the database opened at the top level rather than opening another
notmuch_database_t.
Test output changes because keys are now listed in alphabetical order,
and because a missing database is no longer an error.
Most of the changes are the elimination of notmuch_config_t accessor
use. We also migrate some of the diagnostics to the top level where we
are opening the files in question.
This commit starts the conversion of notmuch-config.c
functionality (as opposed to just interface) to the new config
framework.
The change to T030-config is because of the move of the
canonicalization database paths from the notmuch_config_t accessor to
the internal function _choose_database_path.
This matches functionality in the the CLI function
notmuch_config_get_database_path, which was previously used in the CLI
code for all calls to open a database.
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.
_trial_open can't know if the PATH_ERROR return value will cause the
error message to be returned from the library, so it's up the caller
to clean up if not.
The stat is essentially replaced by the mkdir for error detection
purposes. This changes the default location for backups to make
things tidier, even in non-split configurations. Hopefully there is
not too many user scripts relying on the previous location.
Because the default location may not exist, replace the use of stat
for error detection with a call to mkdir.
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.
Choose sibling directory of xapian database, as .notmuch may not
exist.
libgen.h is already used in debugger.c, so it is not a new dependency
/ potential portability problem.
The new test is in T055-path-config because it uses the helper
function split_config, and because it seems easier to put the
database path related tests in one place.
This changes some error reporting, either intentionally by reporting
the highest level missing directory, or by side effect from looking in
XDG locations when given null database location.
This adds new state variable for the mail root, and uses it most
places db_path was used. The notable exception is dumps from
backups. The latter will be dealt with properly in a future commit.
The main functionality will be tested when notmuch-new is converted to
support split configuration. Here only the somewhat odd case of split
mail root which is actually symlinked to the database path is tested.
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.
The idea is to allow reuse in n_d_create_with_config. This is
primarily code movement, with some changes in error messages to reduce
the number of input parameters.
This is slightly more tidy, but more importantly it allows for re-use
of this code in n_d_create_with_config. That re-use will be crucial
when we no longer call n_d_open_with_config from
n_d_create_with_config.
This removes duplication between the struct element and the
configuration string_map entry. Create a simple wrapper for setting
the database path that makes sure the trailing / is stripped.
In order to open the database in main() for this command, we may need
to re-open it in the (possibly less common) case where crypto options
require write access.
This fixes a bug reported in [1]. In principle it could be possible
avoid one of these reopens, but it complicates the logic in main with
respect to creating new databases.

Recent changes to configuration handling meant the pre-new hook was
run while the database was open read only, limiting what could be done
in the hook. Add some known broken tests for this problem, as well as
a regression test for write access from the post-new hook.
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.
This will allow re-opening in a different mode (read/write
vs. read-only) with current Xapian API. It will also prove useful when
updating the compact functions to support more flexible database
location.
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.
In [1] Gregor Zattler explained the results of his hard work
tracking down a bug in notmuch with long directories. This test
duplicates the bug.

This is the result of running
$ uncrustify --replace --config devel/uncrustify.cfg *.c *.h
in the top level source directory
Line breaks were then adjusted manually to keep argc and argv
together.
Fix use of $TEST_DIRECTORY ($NOTMUCH_BUILDDIR/test/) with use of
$TMP_DIRECTORY ($NOTMUCH_BUILDDIR/test/tmp.T020-compact/ in case
of T020-compact.sh) as root directory where to write test files
and directories.
