Implement DBus API
This ticket tracks the development of the DBus daemon. Current development branch can be found here.
The API is not complete yet but some parts are functional. The daemon, command-line client and tests can be built with: ./autogen.sh --enable-bindings-glib --enable-dbus --enable-tests && make. The daemon tests can be run with sudo GPIODBUS_TEST_DAEMON_PATH=dbus/manager/gpio-manager ./dbus/tests/gpiodbus-test after dbus/data/io.gpiod1.conf is installed to /etc/dbus-1/system.d/. Command-line client tests can be run with sudo PATH=<path to libgpiod>/tests/bash/:$PATH ./dbus/client/gpiocli-test.bash. In order to run these, the daemon must be started in the background first.
A little update: the DBus API is getting close to being functional. The development branch was updated. A big part of the command-line client are ready and can be run with the daemon in the background. I expect to post the series for review in around 2 weeks if nothing happens.
An RFC with the DBus API has been posted to linux-gpio: https://lore.kernel.org/linux-gpio/[email protected]/

It seems the branch was renamed and this URL is broken. Is b4/dbus the correct branch? It's the only branch right now.
Yes! I started using b4 for libgpiod and enrolled the old topic/dbus branch into a managed branch. Sorry.
$ ./autogen.sh --enable-bindings-glib --enable-dbus --enable-tests && make

checking for mount >= 2.33.1... no
configure: error: Package requirements (mount >= 2.33.1) were not met:
Package 'mount' not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables MOUNT_CFLAGS
and MOUNT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I'm on Alpine Linux 3.20.
$ mount --version
mount from util-linux 2.40.1 (libmount 2.40.1: btrfs, namespaces, idmapping, fd-based-mount, statx, assert, debug)
Don't know what else to try.
Looks like some kind of "devel" package for mount is missing. Probably you must run something similar to "apk add ..." But I'm not familiar with Alpine and the available packages etc.
Can't find any.
My last attempt: https://pkgs.alpinelinux.org/packages?page=1&name=%2amount%2a&branch=edge
Tried mount-dev (the alpine convention), libmount (already installed), mount-*, mount*...
@o-alquimista do you have the pkgconfig/mount.pc file anywhere in your system?
@o-alquimista do you have the
pkgconfig/mount.pcfile anywhere in your system?
Tried # find / -type f -name "mount.pc" and got nothing. I'll ask the alpine people on IRC.
It's util-linux-dev. I only found it through this form: https://pkgs.alpinelinux.org/contents?file=mount.pc&path=&name=&branch=edge

I had same issue. My io.gpiod1.conf was stored on bad place because of --prefix=/usr. I fixed that with --sysconfdir=/etc
Ah! So the autotools docs say:
(...) by default sysconfdir will be ‘$(prefix)/etc’, because this is what the GNU Standards
require. When such a package is installed on an FHS compliant system, the installer will
have to set ‘--sysconfdir=/etc’. As the maintainer of the package you should not be
concerned by such site policies: use the appropriate standard directory variable to
install your files so that the installer can easily redefine these variables to match their
site conventions.
So I didn't want to hard-code the path to /etc/.
I understand, I do not want change this behaviour. I only wanted to say @o-alquimista what could be reason for his problem.
Can you run it through both strace and gdb and post results here? The entire strace log and gdb stack trace?

Did @honzamzr 's suggestion help? Is the io.gpiod1.conf in the right place under /etc/dbus-1/system.d/?
Did @honzamzr 's suggestion help? Is the io.gpiod1.conf in the right place under

It was in /usr/local/etc/. I moved it to /etc, restarted dbus, and now gpio-manager is running ok.
Will run some tests.
This ticket tracks the development of the DBus daemon. Current development branch can be found here.
The API is not complete yet but some parts are functional. The daemon, command-line client and tests can be built with:
./autogen.sh --enable-bindings-glib --enable-dbus --enable-tests && make. The daemon tests can be run withsudo GPIODBUS_TEST_DAEMON_PATH=dbus/manager/gpio-manager ./dbus/tests/gpiodbus-testafterdbus/data/io.gpiod1.confis installed to/etc/dbus-1/system.d/. Command-line client tests can be run withsudo PATH=<path to libgpiod>/tests/bash/:$PATH ./dbus/client/gpiocli-test.bash. In order to run these, the daemon must be started in the background first.
Manual tests
gpiocli commands detect and info are working. They don't need to be run as root.
A line must be requested before it can be used in get and set.
gpiocli get: Line 'GPIO18' not managed by gpio-manager, must be requested first
gpiocli request must be run as root, or it fails with "access denied".
$ gpiocli request -c 0 GPIO18
gpiocli request: failed to request lines from chip '0': GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.39" (uid=1000 pid=29317 comm="gpiocli request -c 0 GPIO18") interface="io.gpiod1.Chip" member="RequestLines" error name="(unset)" requested_reply="0" destination=":1.0" (uid=0 pid=28991 comm="gpio-manager")
Requesting a line:
$ doas gpiocli request -c 0 GPIO18
request0
List requested lines:
$ gpiocli requests
request0 (gpiochip0) Offsets: [18]
gpiocli get also needs root.
The help text says gpiocli get: either at least one line or the request must be specified. But if I specify request0 (the request name), it doesn't work:
$ doas gpiocli get request0
gpiocli get: Line not found: request0
This works though:
$ doas gpiocli get GPIO18
"GPIO18"=active
I also tested gpiocli set, and it works as expected.
Automated tests
The cloned repository is on branch b4/dbus. The command I used to configure the project: ./autogen.sh --enable-bindings-glib --enable-dbus --enable-tools --enable-tests && make
I had difficulty running the commands with doas instead of sudo.
For example, doas GPIODBUS_TEST_DAEMON_PATH=/usr/local/bin/gpio-manager ./dbus/tests/gpiodbus-test doesn't work.
doas: GPIODBUS_TEST_DAEMON_PATH=/usr/local/bin/gpio-manager: command not found
And if you move doas after the env var: GPIODBUS_TEST_DAEMON_PATH=/usr/local/bin/gpio-manager doas ./dbus/tests/gpiodbus-test.
not ok /gpiod/gpiodbus/chip/chip_added - gpiodbus-test-FATAL-ERROR: GPIODBUS_TEST_DAEMON_PATH environment variable must be set
Bail out!
So I just executed everything under su -l.

Thanks a lot for testing it and reporting back, really appreciated!

gpiocli requestmust be run as root, or it fails with "access denied".
This is a feature. It's the default, strict config. It can be changed according to your needs, just modify the io.gpiod.conf file.
$ gpiocli request -c 0 GPIO18 gpiocli request: failed to request lines from chip '0': GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.39" (uid=1000 pid=29317 comm="gpiocli request -c 0 GPIO18") interface="io.gpiod1.Chip" member="RequestLines" error name="(unset)" requested_reply="0" destination=":1.0" (uid=0 pid=28991 comm="gpio-manager")
Ah, I need to make this error message more readable.
Requesting a line:
$ doas gpiocli request -c 0 GPIO18 request0List requested lines:
$ gpiocli requests request0 (gpiochip0) Offsets: [18]
gpiocli getalso needs root.The help text says
gpiocli get: either at least one line or the request must be specified. But if I specifyrequest0(the request name), it doesn't work:$ doas gpiocli get request0 gpiocli get: Line not found: request0
Because you need to run it as gpiocli get -r request0. Otherwise the program assumes request0 is a name of one of the lines.
This works though:
$ doas gpiocli get GPIO18 "GPIO18"=activeI also tested
gpiocli set, and it works as expected.Automated tests

You kernel most likely doesn't have the gpio-sim module compiled?

Bash is a requirement for running the tests. We just use COPROC and other bashisms a lot. It's not needed for anything else though.
