tripping the CI.

Link to the previous revision can be found below.

Thanks
Emil

As the README chunk says, disabled by default, since they rely on
internal API/ABI and can break at any point.

Instead everyone affected should work and upstream their plugin into the
bluez project.

As a whole all plugins should be built-in, otherwise they would be using
internal, undocumented, unversioned, unstable API.

Flesh out the external plugin support into a few pre-processor blocks
and simplify the normal path.

Hide the internal API (omit export-dynamic) when built without external
plugins.

Convert the only known external plugin to built-in. It's a tiny 20K
binary that distros ship a separate package for.

Make it a builtin, which allows distros to drop the separate package, it
also enables us to compile out support for external modules - both in
terms of extra code and hide the internal bluetoothd API.

This means that libudev.so is pulled in, which is fine since its ABI has
been stable for over a decade.

Currently, we print "Loading foobar" for every plugin, before we try the
respective init() callback. Instead we handle the latter in a bunch, at
the end of the process.

Do the init() call early, print "Loaded" once it's actually successful
and drop the no-longer "active" tracking.

Just a comment that external plugins support was added to avoid udev
dependency (from sixaxis) in bluetoothd.
(not that I have strong opinion on this, just a note, I don't remember
exactly why it was done, maybe Marcel recalls?)

Thanks, I may have some ideas why.

About 10 years ago (or so) some distributions were shipping
libudev.so.0 while others libudev.so.1. The ABI break was minimal,
although it was a thing.
I remember us doing all sorts of hacks in Mesa trying to pick the
correct one, esp when your system can have .1 while the game (or its
chroot-like environment) has .0 and vice-versa.

I would imagine a similar issue was observed in bluez - but I can only
speculate.

Over the last 5+ years, literally all supported distributions have
moved for libudev.so.1 and the Steam games (and runtime) has both with
some compat quirks to avoid explosions.

I was considering applying this week but if you want to respin this
set to sort out the dependency Im fine with, but I don't think it
would hurt to have a libudev dependency provide we have some means to
disable it in case the system don't intend to support sixaxis plugin.

I don't think I follow: what do you mean with "sort out the dependency"?

Sixaxis is no different to midi where it a) pulls a third-party
library (udev vs alsa) and b) it can be disabled at build. Technically
one can dlopen/dlsym libudev.so, although that should probably be
deferred until needed IMHO.

Thanks
Emil

How about we do something like:

https://gist.github.com/Vudentz/0b8bcb78a8898614fc4848cbf44a0a9f

That way we leave it to the compiler to remove the dead code when
linking but it still build checks which catches errors such as:

make --no-print-directory all-am
  CC       obexd/src/obexd-plugin.o
obexd/src/plugin.c: In function ‘external_plugin_init’:
obexd/src/plugin.c:123:9: error: implicit declaration of function
‘warn’ [-Werror=implicit-function-declaration]
  123 |         warn("Using external plugins is not officially supported.\n");

Not sure why I did not use that from the start. Considering I've done
similar changes in the kernel :facepalm:
