[PATCH] dbus: Let the ptest package install alongside dbus-broker

[PATCH] dbus: Let the ptest package install alongside dbus-broker

[Khem Raj]

dbus-ptest RDEPENDS on dbus, both explicitly and through ptest.bbclass,
and dbus-broker RCONFLICTS dbus. With VIRTUAL-RUNTIME_dbus = "dbus-broker"
(systemd pulls it in) core-image-ptest-dbus fails in do_rootfs:

  package dbus-broker-37-r0.6.cortexa57 conflicts with dbus provided by dbus-1-1.16.2-r0.45.cortexa57
  package dbus-ptest-1.16.2-r0.45.cortexa57 requires dbus, but none of the providers can be installed

The installed tests don't use the system bus. They start private buses
with dbus-daemon (DBUS_TEST_DAEMON) and use dbus-send, so depend on the
dbus-daemon and dbus-tools packages instead and drop the dbus dependency,
like avahi does.

With this the images using dbus-broker as the system bus also pass all 60 dbus
ptests.

Hi Khem,

It looks like this does not go very well. Most builds fail with:

ERROR: Nothing RPROVIDES 'dbus-daemon' (but /srv/pokybuild/yocto-worker/genericx86-64/build/layers/openembedded-core/meta/recipes-core/dbus/dbus_1.16.2.bb RDEPENDS on or otherwise requires it)

https://autobuilder.yoctoproject.org/valkyrie/#/builders/4/builds/4953

Can you have a look at the issue?

Thanks,
Mathieu

sent a v2, it should have added dbus-daemon dependency conditionally. See
if this helps.
