Bug 85642 – keydown and keyup events have zero keycode for some numeric pad keys under Chromium on Linux

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

The keys marked "5", "0"/"Ins" and "."/"Del" generate keydown and keyup events with zero keycode values under Chromium on Linux.  These keys have valid keycodes under Chromium on Windows.

See crbug.com/124755 in the Chromium tracker.

Can we add a unit test for this?

I don't get this. How is that GDK_KP_Begin maps to VKEY_CLEAR?
Various search on google tells me that GDK_KP_Begin is VKEY_NUMPAD5 when numlock is on and undefined otherwise.

You should be able to add a gtest to webkit_unit_tests for this.  windowsKeyCodeForKeyEvent is just a function that you can call directly.

Wez's patch is valid and fixes a serious problem on Linux.

Even if one has a problem with the "case GDK_KP_Begin" the other two entries are undeniably needed.  Every windows keyboard has these buttons, and they are used by people everywhere.

case GDK_KP_Insert:
    return VKEY_INSERT; // (45) INS key
case GDK_KP_Delete:
    return VKEY_DELETE; // (46) DEL key

I'm a bit of a noob here, but if somebody can point me to instructions on how to be a good citizen here, I'll make the fix myself.

The hold up here is that I've not got around to adding unit-tests for windowsKeyCodeForEvent(), which currently has no tests.

I've added a (Linux-only) test under Source/WebKit/chromium/tests.

Gah, my bad - didn't realise that *Gtk* files aren't automatically omitted on non-GTK.  Will fix and re-upload.  Apologies for the noise...

This appears to be causing KeyPadInsert failures in webkit_unittests. e.g.

http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Linux/builds/6820

log output:

(view as text)
KeyCodeConversionTest.KeyPadInsert: 
../../third_party/WebKit/Source/WebKit/chromium/tests/KeyCodeConversionTestGtk.cpp:51: Failure
Value of: windowsKeyCodeForKeyEvent(0xff9d)

Expected: windowsKeyCodeForKeyEvent(0xff63)
Which is: 45

Apologies for the fail caused by the previous patch-set, which had a copy/paste typo I must have introduced just before uploading. It seems that EWS doesn't run the new test, so it wasn't caught. :(

Once again, CQ Powerz required. :)
