cogctl communication to multiple instances does not work

[ventosus]

With two cog instances (built with system DBUS):

cog --gapplication-app-id=com.example.ONE uri
cog --gapplication-app-id=com.example.TWO uri

There is no way to talk to both of them with cogctl by using the object path: (only the first one loaded can be talked to)

cogctl --system --object-path=/com/example/ONE reload -> OK

cogctl --system --object-path=/com/example/TWO reload
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Object does not exist at path ?/com/example/TWO?

There is no way to talk to both of them with cogctl by using the appid:

cogctl --system --appid=com.example.ONE reload
GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "com.example.ONE" does not exist

cogctl --system --appid=com.example.TWO reload
GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "com.example.TWO" does not exist

How should I talk to different cog instances? Am I doing something wrong?

Hello @ventosus - I also have been having trouble with cogctl and dbus.
I wonder if theres something I am missing with my set up.
I am running cog as root in an embedded environment.
The system bus is at /run/dbus/...
The environment variables for dbus are not getting set "automatically" in my case.
Have you tried checking your environment variables (such as DBUS_SYSTEM_BUS_ADDRESS) for dbus?

Please find my post here:
#532

@chrisvollorenew dbus ist set up just fine on my side. my problem is addressing multiple instances of cog. addressing a single instance works just fine.

The same identifiers passed to cog --gapplication-app-id= must be passed to cogctl --appid=:

# Start two instances with different application identifiers
cog --gapplication-app-id=com.example.Cog1 wpewebkit.org
cog --gapplication-app-id=com.example.Cog2 igalia.com
# Load different pages on each using cogctl
cogctl --appid=com.example.Cog1 open webkit.org
cogctl --appid=com.example.Cog2 open apple.com

You can see this in action in the screenshot below (note that -A is the same as --appid=):
