Apparently the -f option to hostname is not portable, and in fact it
does not seem to always behave reasonably in e.g. a chroot.

When compat canonicalize_file_name was introduced, it was limited to
C code only because it was used by C code only during that time.
>From 5ec6fd4d, (lib/open: check for split configuration when creating
database., 2021-02-16), lib/open.cc, which is C++, relies on the
existent of canonicalize_file_name.
However, we can't blindly enable canonicalize_file_name for C++ code,
because different implementation has different additional signature for
C++ and users can arbitrarily add -DHAVE_CANONICALIZE_FILE_NAME=0 to
{C,CXX}FLAGS.
Let's move our implementation into a util library.

Ignoring this return value seems like a bad idea in general, and in
particular it has been hiding one or more bugs related to handling
long directory names.
lib/open.cc:_load_key_file will only open xdg-config files in
$XDG_CONFIG_HOME if it's defined, $HOME/.config will be considered if
and only if XDG_CONFIG_HOME not defined.
Let's unset said variable before running the test.
This is intended to fix the slow behaviour of "notmuch new" (and possibly
"notmuch reindex") when large numbers of files are deleted.
The underlying issue [1] seems to be the Xapian glass backend spending
a large amount of time in db.has_positions when running queries with
large-ish amounts of unflushed changes.
This commit removes two uses of Xapian queries [2], and replaces them with
an approximation of what Xapian would do after optimizing the
queries. This avoids the calls to has_positions (which are in any case
un-needed because we are only using boolean terms here).
[1] Thanks to "andres" on IRC for narrowing down the performance
bottleneck.
[2] Thanks to Olly Betts of Xapian fame for talking me a through a fix
that does not require people to update Xapian.
Without the proposed fix for deletion performance [1], this test is
probably unreasonably slow compared to others at the same
small/medium/large scale.

Certain tools like the address-sanitizer fail if they are not the
first LD_PRELOADed library. It does not seem to matter for our shims,
as long as they are loaded before libnotmuch.
The name is a compromise between keeping function names from getting
too long, and avoiding confusion with the newer notmuch_config library
API. Try to make clear that the residual functionality is only about
updating configuration files.
This will allow simplifying the subcommand interface.
Change the internal API to notmuch_config_open to not tie it to the
implementation of subcommands in notmuch.c.
It also fixes a previously broken test, since notmuch_config_open does
not understand the notion of the empty string as a config file name.
There are two small code changes. The main one is to retrieve the
possibly updated config file name found during the database opening
call. The second change is to allow empty config file names, as
a (currently broken) way of specifying that configuration should only
be taken from the database.
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.
Eventually we want to do all opening of databases in the top
level (main function). This means that detection of missing databases
needs to move out of subcommands. It also requires updating the
library to use the new NO_DATABASE status code.
Previously the fact that some configuration options were only stored
in the database (and thus editing the config file had no effect) was a
source of user confusion. This was fixed with the series ending at
d9af0af164.
On the other hand, the underlying partition of config options into
those stored by default in the database and those stored in the config
file remained. This is also confusing, since now some invocations of
"notmuch config set" modify the config file, and others silently
modify the database instead.
With this commit, it is up to the user to decide which configuration
to modify. A new "--database" option is provided for notmuch config to
enable modifying the configuration information in the database;
otherwise the default is to update an external config file.
The goal at this point is to remove the dependence on
notmuch_config_get_* without breaking any existing functionality. This
is a step towards removing notmuch_config_get_* in a future commit.
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.
