Activation: Service providers providing more than one service
Fri, 09 Jan 2004 17:24:51 +0100
Trying to figure out the best way of solving when several services are
handled by the same binary. For example a binary that has two services A
and B, a client activates Service A but before the provider has
registered Service B another client tries to activate it. To avoid
having two binaries spawned the bus needs to be aware that these two are
both handled by the same binary.
This can be done in two ways.
1) Match on the exec: The bus sees that Service B is handled by the same
exec and doesn't try to executes it again but just puts the caller in
the pending activation queue. Each service has it's own .service file
which points to the same binary.
2) Have a service provider that can provide several services: For
example a .service file would contain information about all the
services a certain service provider provides, example:
The bus can then see that when someone tries to activate
org.gnome.Foo.ServiceB while it is still activating service provider
org.gnome.Foo it should wait until the service provider is activated.
