Bug 35870 – Upstream iPhone KeyEvent platform code and share with Mac platform

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joseph Pecoraro]

The iPhone and Mac platforms both share a large amount of code, yet still have their differences. It would be nice to have a place to put shared code. Something like platform/cocoa, and a PLATFORM(COCOA) flag. Also, we should move up some of the platform/iphone that uses the shared code.

Updated to ToT for Bots

- bots showed an svn-apply issue with the XCode project, so I updated the patch to ToT.

I was asked to break this up a little, so I broke this apart into 3 patches.

I also removed the PLATFORM(COCOA) flag concept.  I don't see a need for it if only the Mac / iPhone platforms decide to include / use the new files. Are there build configs that are greedy enough to grab these files unless I protect them with a guard?

[Joseph Pecoraro]

I have an obvious mistake in Part 2. I call windowsKeyCodeForKeyCode when I should call windowsKeyCodeForCharCode. Tests caught these pretty quick.

Looks like it was in Part 3. So I've attached an updated version. Passes the tests locally now.

Please change the tabs to spaces in the header file to correct the style issues.

Actually, two more things:

- You need to add these files to the Xcode project file.
- The *.mm file needs #if PLATFORM(IPHONE)/#endif macros around its source so that it doesn't compile for Mac.

You can do the above in a follow-up patch as well (and add #if PLATFORM(MAC)/#endif macros around KeyEventMac.mm as well).

So the MAC and IPHONE platforms share the same XCode project and the PLATFORM(X) macros pick and choose the files wanted to build for a particular platform?

Nit:  usually we don't use a "!" in this comment for headers.  Darin Adler mentioned on webkit-dev that this comment is unnecessary, so you may optionally remove it.

Thanks for using an "svn mv" to create the KeyEventCocoa.mm file!

I think this should be:

    return keyIdentifierForCharCode(c);

as I don't see a keyIdentifierForKeyCharCode() method in the patch.

Even though I created an svn checkout specifically for the svn copy, by putting "the move" in a separate patch from "the changes" git figured out it was a copy as well.

Good catch! I caught the Mac build through tests, but I didn't fix this typo.
