[webkit-dev] assumption about point packing in multit-touch tests
Hello, I'm working in adding support for the Touch Events W3C API to the Clutter port (and plan to do the same for the Gtk+ one afterwards) and I'm finding a problem when running the tests because they assume that the underlying platform allows packing touch point updates within single touch events. Clutter (and Gtk+, for that matter) provide thin APIs on top of XInput's which does no packing at all: each touch point update is a touch event. Tests such as basic-multi-touch-events-limited.js assume that the platform is able to emit touch events that contain more than one touch point update and also that WebCore will get the same grouping of touch points, but that's not true in XInput-based platforms. Though the W3C spec allows packing more than one touch point update in a single touch event, it says nothing about how these updates should be packed, so I think that the current tests are too restrictive and should be relaxed to stop assuming anything about how the updates are packed into events. I would change the tests to check that after generating a series of touch point updates, the web page has received each of those touch point updates, but not check anything about how they were packed in touch events. Does it make sense to everybody? Thanks, Tomeu ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev
