Subject: tests: Support setting the test client input dynamically
X-Git-Tag: upstream/5.0.0~266
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=468bd0b9c87e3dc6bf152af3bf48a16dc1ed696c;p=platform%2Fupstream%2Fweston.git

tests: Support setting the test client input dynamically

The current test client code waits for all wl_seat globals to arrive
before checking them and deciding which one is the test seat global to
use for the input object. Test code that needs to add/remove test seats
would have to call the client_set_input() function for any seat changes
to take effect. Although we could allow this by making
client_set_input() public, we would be exposing unecessary
implementation details.

This commit applies any seat changes immediately upon arrival of the
seat name, freeing test code from needing to call extra functions like
client_set_input(). To achieve this the call to input_data_devices() is
moved from client_set_input() to the seat name event handler.

This commit also moves the check that all seats have names to an
explicit test. To support this test, inputs corresponding to non-test
seats are not destroyed (unless their seat global is removed), as
was previously the case.
