Bug 66105 – [chromium] Add support for gesture events in the DRT

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Sadrul Habib Chowdhury]

This patch adds support for gesture events in the DumpRenderTree. This will allow testing gesture recognition code and gesture handling code separately.

There aren't any gesture-handling code at the moment. So there are not layout tests with this patch. Gesture-handling code with layout tests are forthcoming.

I don't think this is strictly true. You could add a layout test to invoke the PlatformGestureEvent for tap and scroll as results from touch events in touch-gesture-click.html and touch-gesture-scroll.html but I would hope that this could happen in a subsequent patch.

Ah, indeed. I have added a layout-test for the scenario you explain for tap (and added WebInputEvent::GestureTap corresponding to PlatforGestureEvent::TapType).

[Robert Kroeger]

Looks reasonable to me. (Though it will probably have to change to track changes to PlatformGestureEvent.)

Technically we need fishd to approve the WebKit API change, but I think this is probably ok.

[Adam Barth]

+fishd for (extremely minor) WebKit API change.

fishd, I marked the patch R+ because the change looked fine, but I wanted you to see the patch.  Let me know if you'd prefer to give the official R+ for these sorts of changes in the future.

Looks like the error was caused by a missing 'Reviewed by' line in Tools/ChangeLog? My bad, it got removed when I was editing the changelog file. I have added back that line.

The test added by this patch is failing on Qt:
http://build.webkit.org/results/Qt%20Linux%20Release/r93002%20(36451)/fast/events/touch/gesture/gesture-click-pretty-diff.html

Why are we adding this test to fast/events/touch if it were to fail on all other platforms but chromium?  Are there bugs filed for each port to implement this DRT feature?

The tests are not Chromium-specific.  The fact that they fail on other platforms currently doesn't make them Chromium-specific.

> Are there bugs filed for each port to implement this DRT feature?

The fast/events/touch should be skipped on ports that don't implement Touch events.  If the ports implement Touch events but don't have this DRT feature, then we should file bugs to implement the DRT feature (or just note it in the Skipped list).
