Hi all, I've been trying to create a pam module that sends a dbus message to a service using gdbus, but it's failing in a way I can't figure out.
I've used gdbus and gdbus-codegen for both the service and the caller, and it all seems to work fine when I call the service from a simple test application. However, when I move the same code from the test program to a pam module I then get the unexpected behaviour. The first time the pam module is run I call *_proxy_new_for_bus_sync to return a proxy and when I use this to call the service it all works fine. The second time it's run the same *_proxy_new_for_bus_sync function returns a NULL proxy, but apparently without returning any error. The third time it's run the *_proxy_new_for_bus_sync function hangs and never returns. This behaviour happens when I use the pam module with the unity lock screen, but if I use pamtester instead, everything works fine every time. I'm confused for two reasons. First, I find it odd that the behaviour is inconsistent across executions. Second *_proxy_new_for_bus_sync is returning NULL without returning an error, which the documentation doesn't seem to cover. If anyone has any suggestions for what might be going on, I'd be grateful. I uploaded a minimal working example to github: Service: https://github.com/llewelld/dbus-pam-test/blob/master/src/service.c Test app: https://github.com/llewelld/dbus-pam-test/blob/master/src/test.c Pam module: https://github.com/llewelld/dbus-pam-test/blob/master/src/pam_test.c And in case it's helpful, the output to syslog from running these is here: https://github.com/llewelld/dbus-pam-test/blob/master/log-output.log David -- Website: http://www.flypig.co.uk _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
