Bug 48552 – Mouse events never reach Flash in WebKit2 on Mac (asserts in Debug builds)

• Component: WebKit2
• Status: RESOLVED FIXED

[Adam Roben (:aroben)]

To reproduce:

1. Go to http://youtube.com/ and try to interact with any video

The video doesn't respond to any mouse events. In Debug builds, you'll get an assertion in ArgumentDecoder::decodeBytes:

ASSERT(size == bufferSize);

size is 56, bufferSize is 52

[Adam Roben (:aroben)]

This happens when handling a HandleMouseEnterEvent. Presumably the issue is that WebMouseEvent is 52 bytes in 32-bit builds, and 56 bytes in 64-bit builds. Perhaps this is due to different padding?

Seems like we should add a WebEvent.cpp, or perhaps even WebMouseEvent.cpp/h!

Not sure if it is, but this should all be on one line!

Guys, it wasn't a fair-play game ... Qt EWS was red, but
you committed the wrong patch, and the Qt build is broken 
since 1,5 hours ago. :-S

Sorry for the trouble. I've been paying attention to the Qt-EWS in general, and find it extremely useful. I guess I wasn't thinking on this one. Thanks for cleaning up my mess!
