Zbigniew Jędrzejewski-Szmek	e48a1e3423	mailmap: add entry to fix authorship of commit `471cffcfb0` was committed on a debug VM where I didn't have git set up properly.	2019-10-21 15:10:58 +02:00
Zbigniew Jędrzejewski-Szmek	8163b9f900	logind: fix emission of PropertiesChanged for users The same as parent commit, but users. This is the third and last foo_object_find() function in logind, so I think that this particular family of bugs is finally squashed.	2019-10-21 15:07:36 +02:00
Zbigniew Jędrzejewski-Szmek	8cc64c2a36	logind: fix emission of PropertiesChanged on seats The story is the same as in 471cffcfb0e005b7c4044b3b52cc4f25d217efac: device_attach() → seat_send_changed() → sd_bus_emit_properties_changed_strv() → emit_properties_changed_on_interface() → node_vtable_get_userdata() → seat_object_find(), which returns 0 because message == NULL. But when we are emitting a signal, message is always NULL. Removing the overeager check and assert in the called function allow the signal to be emitted. Fixes #13769.	2019-10-21 15:05:58 +02:00
