#39145: glib2, glib2-devel: add MacPorts specific dbus session support to GDbus. -------------------------+-------------------------- Reporter: devans@… | Owner: ryandesign@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.1.3 Keywords: dbus | Port: glib2 -------------------------+-------------------------- An increasing number of GNOME and other GTK+ applications emit the following error or similar on start up: {{{ Error spawning command line `dbus-launch --autolaunch=73b3a03997e9d04800d0112b50b3fbad --binary-syntax --close- stderr }}} This has been an issue for some time (#28077 and more recently #37101). The problem appears to be coming from g_dbus_address_get_for_bus_sync() in the GIO GDbus interface. Enabling GDbus address debugging {{{ export G_DBUS_DEBUG=address }}} shows the following {{{ GDBus-debug:Address: In g_dbus_address_get_for_bus_sync() for bus type `session' GDBus-debug:Address: env var DBUS_SESSION_BUS_ADDRESS is not set GDBus-debug:Address: env var DBUS_SYSTEM_BUS_ADDRESS is not set GDBus-debug:Address: env var DBUS_STARTER_BUS_TYPE is not set GDBus-debug:Address: Running `dbus-launch --autolaunch=73b3a03997e9d04800d0112b50b3fbad --binary-syntax --close- stderr' to get bus address (possibly autolaunching) }}} In fact, a code inspection shows that GDBus only provides support for Unix and Windows platforms and shows Mac OS X support as a TODO. Attached is a proposed patch that adds MacPorts specific dbus session support by using launchctl to lookup the dbus session socket and form the appropriate address from that. After applying this patch, most if not all occurrences seem to be fixed. I have seen no problems after upgrading all outstanding GNOME ports to the 2.32.1 level including gconf. Typical debug output is now {{{ GDBus-debug:Address: In g_dbus_address_get_for_bus_sync() for bus type `session' GDBus-debug:Address: env var DBUS_SESSION_BUS_ADDRESS is not set GDBus-debug:Address: env var DBUS_SYSTEM_BUS_ADDRESS is not set GDBus-debug:Address: env var DBUS_STARTER_BUS_TYPE is not set GDBus-debug:Address: launchctl command line: `launchctl getenv DBUS_LAUNCHD_SESSION_BUS_SOCKET' GDBus-debug:Address: launchctl stdout: 0000: 2f 74 6d 70 2f 6c 61 75 6e 63 68 2d 4b 4a 57 39 /tmp/launch- KJW9 0010: 72 7a 2f 75 6e 69 78 5f 64 6f 6d 61 69 6e 5f 6c rz/unix_domain_l 0020: 69 73 74 65 6e 65 72 0a 00 istener.. GDBus-debug:Address: Returning address `unix:path=/tmp/launch- KJW9rz/unix_domain_listener' for bus type `session' }}} Submitting as an enhancement since this is not strictly a bug but a lack of upstream support. Propose submitting to upstream after wider testing by others. -- Ticket URL: <https://trac.macports.org/ticket/39145> MacPorts <http://www.macports.org/> Ports system for OS X
