[systemd-devel] Fwd: sdbus-filedescriptor does reproducibly NOT get triggered in a specific situation

[Jan Mueller]

Dear systemd folks,


I have the following issue:

An application does not receive dbus signals on its dbus file descriptor
*while waiting* for a

dbus-method response. Considered time frame: between sending the
method-call and receiving

its response. After the response is being received, the (indefinitely)
queued signal is not delivered

until another signal / method call triggers the sdbus file descriptor
(which is supervised by

select()/epoll()).



I committed a brief example with some more extensive explanation to:

Thanks in advance and best regards,

Jan
