Hi Peter,
Sorry for replying off-list first.
Thanks for the work you've put into this. I haven't spent a lot of time
testing the new code, but here are my first impressions. You're
probably aware of most of the issues below already, but I'll mention
them just in case.
* The biggest issue for me right now is reporting of XI1 (see the
attached test program). XSelectExtensionEvents and
XGrabDevice/XGrabDeviceButton will only report press events; motion and
release events are lost.
* A driver sending a proximity event crashes the server.
* XIGrabButton always fails with a BadDevice error.
* It seems to be pretty easy to crash the server using XI1 applications.
I'll provide more information later
* libXi doens't support parallel builds (make -j2) anymore.
I haven't played with XI2 code a lot yet, but the interface seems a lot
nicer than XI1 so far. I can't think of any features that are missing
right now except for button grabs and XTest support.
Thanks,
Tom
