I've spent some time to investigate this bug, here's my understanding. The inactivity timer operates on a property of the OA.Manager object, called "idle". If "idle" becomes true and stays true for the whole duration of the timeout period (which by default is 5 seconds, and in the tests is set to 2 seconds), then the service process quits.
The "idle" property is set to false if any client makes a call on the D-Bus interface, and stays false until there are no active calls from any client (that is, until not all client requests have been answered). This means that the D-Bus service is free to come and go during the lifetime of a long-running client, depending on whether the client is actively using the D-Bus service or not. But as I wrote in the comment above, this is not playing nice with the testAccountChanges() test case, which makes one D-Bus method call on its starts and then expects the service to stay alive and deliver change notifications. We either need to increase the timeout during the tests (I wouldn't do that, since the next test duration would then need to be increased, to be meaningful) or place some method calls on the D-Bus service in testAccountChanges(), to keep the service alive. I'll try to go for this latter option. Note: in the real world, this is not a problem: clients cannot directly modify the accounts DB (it's read-only), all accounts modifications are done through the online-accounts-service process (which is part of the ubuntu-system-settings-online-accounts project), which was also chosen to be the host for the OnlineAccounts.Manager D-Bus service. This means that whenever an account is modified, the OnlineAccounts.Manager D-Bus service will be active and able to detect modifications on the accounts DB and signal them out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1603706 Title: Possible races in tst_daemon tests.
