[Message part 1 (text/plain, inline)]

Package: emacs
Version: 24.4.50
Severity: minor

Current trunk on x86_64 RHEL 6.5, under XFCE 4.10.
I doubt this is a real issue, but dbus-test02-register-service-session
fails for me:

F dbus-test02-register-service-session
    Check service registration at `:session'.
    (ert-test-failed
     ((should
       (dbus-ping bus dbus-service-emacs 100))
      :form
      (dbus-ping :session "org.gnu.Emacs" 100)
      :value nil))

Well, this is strange. When I run "dbus-monitor" in another shell in
parallel, the test runs successful. When there is no dbus-monitor
running, the test fails.

Usually I have enabled dbus-monitor when running tests, in order to see
whether everything works fine with D-Bus ...

Same behaviour in the emacs-24 branch. Will debug further. But this
looks hard to solve.

Best regards, Michael.

It is `dbus-ping' indeed, which behaves different when there is a
running dbus-monitor. I still don't understand why.

Anyway, I have changed in the emacs-24 branch the checks in
`dbus-test02-register-service-session' not to use `dbus-ping'. It runs
successfully now.

I would like to keep this bug open until we know what's up with
`dbus-ping'. When this is fixed, another test case shall be added to
dbus-tests.el as well. This is for the trunk.

Best regards, Michael.

Well, I've fixed this in the trunk. The ofd.Peer.Ping method must be
registered for all own services. There is also a corresponding test case
in dbus-tests.el.

Best regards, Michael.
