I'm resending it once more but with commits squashed into how they'll appear
in git once applied upstream. I think the code is in good enough shape that
it can now go into the master branch and any further development can happen
from there.
Big thanks to Philip Withnall <philip@tecnocode.co.uk> for his thorough review
of this series. I think I addressed most of the issues pointed out.
This series introduces the D-Bus API definition and its implementation in the
form of a GPIO manager daemon and a companion command-line client as well as
GLib bindings to libgpiod which form the base on which the former are built.
While I split the GLib and D-Bus code into several commits for easier review,
I intend to apply all changes to bindings/glib/ and dbus/ as two big commits
in the end as otherwise the split commits are not buildable until all of them
are applied.
The main point of interest is the D-Bus interface definition XML at
dbus/lib/io.gpiod1.xml as it is what defines the actual D-Bus API. Everything
else can be considered as implementation details as it's easier to change
later than the API that's supposed to be stable once released.
The first two patches expose the test infrastructure we use for the core
library and tools to the GLib bindings and dbus code. Next we add the GLib
bindings themselves. Not much to discuss here, they cover the entire libgpiod
API but wrap it in GObject abstractions and plug into the GLib event loop.
Finally we add the D-Bus code that's split into the daemon and command-line
client. I added some examples to the README and documented the behavior in
the help text of the programs as well as documented the interface file with
XML comments that gdbus-codegen can parse and use to generate docbook output.
For D-Bus, most of the testing happens in the command-line client bash tests.
It has a very good coverage of the daemon's code and also allows to run the
daemon through valgrind and verify there are no memory leaks and invalid
accesses.
Changes in v5:
- squash GLib bindings and D-Bus commits into two big commits
- Link to v4: https://lore.kernel.org/r/20240807-dbus-v4-0-64ea80169e51@linaro.org
Changes in v4:
- fix generating GObject introspection data
- use GLib doc blocks with introspection annotations suitable for generating
docs with gi-docgen
- various comment and doc tweaks
- Link to v3: https://lore.kernel.org/r/20240718-dbus-v3-0-c9ea2604f082@linaro.org
Changes in v3:
- make gpio-manager run as its own user in the systemd service file and add
udev rules that automate the group assignment for gpiochips
- add sandboxing options to the service file for an overall exposure score
from systemd-analyze of 2.3
- enable introspection for GLib bindings
- set the minimum required GLib version for gdbus-codegen
- fix time units in dbus docs
- change the D-Bus type for Chip's path to byte-array
- change the naming convention in strings: s/DBus/D-Bus/g
- add the "unknown" value to the EventClock property and document how to
interpret other unrecognized values
- various doc updates
- don't set environment variables from the daemon code, use the provided
g_log_writer_default_set_debug_domains() helper
- use g_build_filename() where appropriate
- use g_steal_pointer() to improve error propagation
- use G_PARAM_STATIC_STRINGS across all properties
- use G_GNUC_PRINTF() in g_gpiod_set_error_from_errno()
- change the library's namespace to Gpiodglib/GPIODGLIB/gpiodglib_
- remove the "handle" properties in favor of passing the core libgpiod pointers
to GObjects directly after they're constructed
- add typedefs to property enums for better build-time safety
- don't use g_value_set_static_string() for strings that are not really static
across the entire lifetime of the program
- rework the code for internal property setting and getting
- add Requires.private: libgpiod to gpiod-glib pkgconfig file
- Link to v2: https://lore.kernel.org/r/20240628-dbus-v2-0-c1331ac17cb8@linaro.org
Changes in v2:
- fixed most segfaults I noticed (or was made aware of by others) in RFC
- improve the code in GLib examples
- make command-line tests pass shellckeck
- fix build issue resulting in implicit pointer-to-int casting on some
platforms
- many small tweaks, fixes and improvements all over the place but without
changing the API
- fix a bunch of memory leaks reported by valgrind
- Link to v1: https://lore.kernel.org/linux-gpio/20240412122804.109323-1-brgl@bgdev.pl/

In order to allow the upcoming GLib and DBus bindings to reuse the test
code, let's put all common elements into reusable libtool objects and
export the relevant symbols in internal headers.

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
In order to allow the upcoming DBus command-line client tests to reuse the
existing bash test harness, let's put the common code into an importable
file and rename run_tool to run_prog to reflect that it now can run any
program.

+High-level, object-oriented bindings for C++, GLib, python3 and Rust are
+provided. They can be enabled by passing --enable-bindings-cxx,
+--enable-bindings-glib, --enable-bindings-python and --enable-bindings-rust
+arguments respectively to configure.
C++ bindings require C++11 support and autoconf-archive collection if building
from git.
+GLib bindings requires GLib (as well as GObject, GIO and GIO-Unix) v2.54.
+
Python bindings require python3 support and libpython development files. Please
refer to bindings/python/README.md for more information.

+DBUS
+----
+
+A commonly requested feature for the GPIO character device was state persistence
+after releasing the lines (as a kernel feature) or providing a central authority
+(in user-space) that would be in charge of keeping the lines requested and in a
+certain state (similarily to how the sysfs ABI works). DBus API has been
+provided to address this requirement. We define an interface covering the
+majority of the GPIO chardev's functionality and implement it from both the
+server and client sides in the form of the gpio-manager daemon and the gpiocli
+command-line utility for talking to the manager.
+
+DBus support can be built by passing --enable-dbus to configure. The daemon
+is bundled with a systemd unit file and an example configuration file for the
+io.gpiod1 interface that allows all users to access basic information about the
+GPIOs in the system but only root to request lines or change their values.
+
+With the manager running the user can run gpiocli to control GPIOs by asking
+gpio-manager to act on their behalf:
+
+ # Detect chips in the system.
+ $ gpiocli detect
+ gpiochip0 [INT34C6:00] (463 lines)
+
+ # Request a set of lines. Note that gpiocli exits immediately but the
+ # state of the lines is retained because it's the gpio-manager that
+ # requested them.
+ $ gpiocli request --output foo=active
+ request0
+
+ # Previous invocation printed out the name of the request by which the
+ # caller can refer to it later. All active requests can also be inspected
+ # at any time.
+ $ gpiocli requests
+ request0 (gpiochip1) Offsets: [5]
+
+ # We can print the information about the requested line using the
+ # information above.
+ $ gpiocli info --chip=gpiochip1 5
+ gpiochip1 5: "foo" [used,consumer="gpiocli request",managed="request0",output,push-pull]
+
+ # We can now change the value of the line.
+ $ gpiocli set foo=inactive
+
+ # And read it.
+ $ gpiocli get foo
+ "foo"=inactive
+
+ # We can even reconfigure it to input and enable edge-detection.
+ $ gpiocli reconfigure --input --both-edges request0
+
+ # And wait for edge events.
+ $ gpiocli monitor cos
+ 21763952894920 rising "foo"
+
+ # And finally release the request.
+ $ gpiocli release request0
+
+For more information please refer to the output of gpiocli --help as well as
+gpiocli <command> --help which prints detailed info on every available command.
+
+Of course - this being DBus - users can talk to gpio-manager using any DBus
+library available and are not limited to the provided client.

==========
-* implement dbus API for controlling GPIOs
-
-A common complaint from users about gpioset is that the state of a line is not
-retained once the program exits. While this is precisely the way linux
-character devices work, it's understandable that most users will want some
-centralized way of controlling GPIOs - similar to how sysfs worked.
-
-One of the possible solutions is a DBus API. We need a daemon exposing chips
-and lines as dbus objects and allowing to control and inspect lines using
-dbus methods and monitor them using signals.
-
-As of writing of this document some of the work has already been done and the
-skeleton of the dbus daemon written in C using GLib has already been developed
-and is partially functional.

* implement a simple daemon for controlling GPIOs in C together with a client

+
+ Requests a set of lines and makes it possible for the users of this API
+ to manipulate them depending on the line configuration.
+
+ Line configuration is a tuple of two arrays. The first one contains
+ mappings of arrays of line offsets to sets of line settings. The second
+ contains the list of default output values which are only used in output
+ mode.
+
+ Available line config options:
+
+ "direction" => String representing the line direction. Accepts the
+ following values: "input", "output".
+ "edge" => String representing the edge detection setting. Accepts the
+ following values: "falling", "rising", "both".
+ "active-low" => Boolean representing the active-low setting.
+ "drive" => String representing the drive settings. Accepts the
+ following values: "push-pull", "open-drain", "open-source".
+ "bias" => String representing the internal bias settings. Accepts the
+ following values: "disabled", "pull-up", "pull-down", "as-is".
+ "debounce-period" => Debounce period in microseconds represented as a
+ signed, 64-bit integer.
+ "event-clock" => String representing the clock used to timestamp edge
+ events. Accepts the following values: "monotonic",
+ "realtime", "hte".
+
+ Output values are applied to the lines in the order they appear in the
+ settings mappings.
+
+ Example variant that allows to request lines at offsets 1, 5 and 11 in
+ output, push-pull and active-low modes and specifies the output values
+ as active (as visualized with g_variant_print()):
+
+ // Line config tuple
+ (
+ // Array of line settings mappings
+ [
+ // Single mapping tuple
+ (
+ // Offsets to map
+ [1, 5, 11],
+ // Line settings dict
+ {
+ 'direction': <'output'>,
+ 'drive': <'push-pull'>,
+ 'active-low': <true>
+ }
+ )
+ ],
+ // Output values
+ [1, 1, 1]
+ )
+
+ Request configuration is a hashmap mapping names of the available config
+ options to their values wrapped in a variant.
+
+ Available request config options:
+
+ "consumer" => Consumer name as a string
+ "event-buffer-size" => Requested size of the in-kernel edge event
+ buffer as an unsigned 32-bit integer.
+
+ The object path to the new request is returned on success. The user
+ should wait for it to appear before trying to use the requested lines in
+ any way.

Thanks for doing this!
I was on the long vacation and would not have time to look into this in months,
I think. So whenever this lands into Buildroot, I will use it and hence try to
test the thingy.

Strange, I'd expect from this code to detect pre-existing chips immediately,
but this is not what I observe in practice:
$ gpiocli info --chip=gpiochip0 | head -n 1
gpiochip0 - 24 lines:
$ gpiocli wait --chip=gpiochip0 --timeout=1
gpiocli wait: wait timed out!
(without timeout it would wait endlessly)
This is not expected, right, otherwise it would be counter-intuitive and racy?

gpiochip0 here is the device name. It's dynamic so you cannot use it
with gpiocli wait as you cannot know it in advance. You need to use
the label of the chip instead.
IOW it's a feature. :)

Thanks for the quick reply!
My bad! Indeed it works as intended with labels!
I think I've found something else, but I didn't have time to look into it deeper:
$ gpiocli info POLA_RS485_2
gpiochip0 2: "POLA_RS485_2" [used,consumer="gpio-manager",managed="request14",output,push-pull]
$ gpiocli reconfigure --input --both-edges request14
gpiocli reconfigure: Failed to reconfigure lines: GDBus.Error:io.gpiod1.ReconfigureFailed: failed to reconfigure lines: No such device or address
$ gpiocli reconfigure --input request14
$ gpiocli reconfigure --input --both-edges request14
gpiocli reconfigure: Failed to reconfigure lines: GDBus.Error:io.gpiod1.ReconfigureFailed: failed to reconfigure lines: No such device or address
journal:
gpio-manager[3043]: failed to reconfigure GPIO lines on request '/io/gpiod1/requests/request14': failed to reconfigure lines: No such device or address
$ gpiocli info POLA_RS485_2
gpiochip0 2: "POLA_RS485_2" [used,consumer="gpio-manager",managed="request14",input]
For me it happens with all GPIOs I've tried, I can reconfigure output to input,
but not set edge-detection, neither simultaneously, nor after output->input configuration.
However I don't have any problems to configure edge-detection if I do "gpiocli request".
Just for the case it rings any bells, otherwise I'll look into it in the coming days...

Does your driver support edge detection? Does it work with the
first-time request? Does it work with gpiomon without going through
the manager?

Indeed! You are right again! It's the driver not supporting edge detection!
I've just performed the same operation with a proper chip:
$ gpiocli reconfigure --input --both-edges request4
$ echo $?
0
Thanks for you patience and quick support Bartosz!
PS. Maybe it's an idea for different error code in this case...
