[oe-core][PATCH] dbus: disable ptest if using dbus-broker

[oe-core][PATCH] dbus: disable ptest if using dbus-broker

[Markus Volk]

'inherit ptest' adds a runtime dependency on ${PN} that conflicts with
'RCONFLICTS:${PN} = "dbus"' in the dbus-broker recipe.

This commit attempts to fix an issue where VIRTUAL-RUNTIME_dbus is set to
'dbus-broker' and ptest is included in DISTRO_FEATURES by installing ptest
only when dbus is used as the daemon.

Otherwise do_rootfs fails with:
Error:
 Problem: package libsdbus-c++-ptest-2.2.1-r0.corei7_64 from oe-repo requires dbus-broker, but none of the providers can be installed
  - package dbus-broker-37-r0.corei7_64 from @System conflicts with dbus provided by dbus-1-1.16.2-r0.corei7_64 from oe-repo
  - package dbus-broker-37-r0.corei7_64 from oe-repo conflicts with dbus provided by dbus-1-1.16.2-r0.corei7_64 from oe-repo
  - package dbus-ptest-1.16.2-r0.corei7_64 from oe-repo requires dbus, but none of the providers can be installed
  - conflicting requests

As far as I know, dbus-broker is only meant to replace the daemon itself,
but it uses the same environment as dbus and is still dependent on parts of the
dbus recipe. A more robust solution would therefore be to remove the line
containing RCONFLICTS from 'dbus-broker', since dbus and dbus-broker are not
technically mutually exclusive as long as you don't run both at the same time.
However, I'm aware that this was done for the sake of cleanliness.

So the situation is you have an image that uses dbus-broken but as that is just the daemon you also have libdbus (from dbus.bb), and then using the ptest-pkgs IMAGE_FEATURE you automatically get dbus-ptest installed, which then tries to pull in the dbus daemon.  Correct?

It feels like being able to run the dbus tests against dbus-broker would be a good thing.  Do you know if this is feasible?  I’m wondering if the dependency on a daemon should be some virtual name that dbus and dbus-broken provide.

Cheers,
Ross

Resend this answer because it was bouncing back

The situation is that I want to use dbus-broker but not additionally 
libdbus. dbus-broker.bb adds a runtime dependency on dbus-common and 
dbus-tools.

<https://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-core/dbus/dbus-broker_37.bb#n38>

Thats why dbus recipe is built despite setting VIRTUAL_RUNTIME_dbus = 
"dbus-broker" and because of that we end up with a runtime dependency 
on dbus if ptests
is in DISTRO_FEATURES.

<https://git.openembedded.org/openembedded-core/tree/meta/classes-recipe/ptest.bbclass#n26>

That causes an error at do_rootfs, because dbus-broker.bb makes dbus 
and dbus-broker mutually exclusive:

<https://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-core/dbus/dbus-broker_37.bb#n37>

I dont know, if the dbus tests are meant to be run with dbus-broker but 
dbus-broker installs its own ptest. Shouldn't that be sufficient?
