The *_SYNTH event constants are a bit confusing. We should rename them to be clearer.

NS_MOUSE_ENTER_SYNTH -> NS_MOUSE_OVER
NS_MOUSE_EXIT_SYNTH -> NS_MOUSE_OUT
NS_DRAGDROP_LEAVE_SYNTH -> NS_DRAGDROP_LEAVE

And maybe rename NS_MOUSE_ENTER to NS_MOUSE_ENTER_WIDGET and NS_MOUSE_EXIT to NS_MOUSE_EXIT_WIDGET.

Remove redundant NS_DRAGDROP_OVER_SYNTH and NS_DRAGDROP_EXIT_SYNTH
We should also audit uses of these to ensure the right constant is being used in the right place.
Hi Neil,

I would like to work on this bug.
So I should rename these macro in widget/BasicEvents.h and all the .h/.cpp which use these macro, 
am I correct?
Hi Anthony. Thanks for taking this bug.

You are correct. Rename those macros in each .h and .cpp file where they occur. Let me know if you need any help.
Hi Neil,

How do I test all the changes I made is no mistakes before submitting a patch?

Should I clone the entire source tree and build?

Or is there any document for the beginner like me who tries to contribute?

Thank you.

I'd recommend building the source, if only as an exercise in learning how to do it and if you'd like to contribute to other bugs.

For this bug though, since this mostly involves replacing constant names, as long as you're confident in your editing C++ skill, you might be able to get by without it. You'll need to modify a couple of files that are specific to certain platforms though (Windows, Mac and Linux).

We use an automated testing system called 'Try' that we can submit patches to and various machines run our test suites automatically. Results are posted at https://treeherder.mozilla.org/#/jobs?repo=try

A key value of this to test patches on different platforms, operating system versions and configurations that you don't normally use. I assume you don't have access to our Try system so you can post a patch to this bug and I or someone else can do so for you. You can then look at the results and fix and issues that arise.

We have documentation about building and testing at https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide

Here is my first patch.

OK great. Are you ready to have it tested? When I applied it I got a merge conflict. Perhaps someone checked in some code to the same file today.

I don't have the permission to perform 'Try' test. I just make sure it won't build fail. I will pull the newest code and update the patch.

After pulling from the repository, I made this patch. However, I'm afraid that there will be more conflicts if someone commits new change in this period.

According to the failure summary:
c:\builds\moz2_slave\try-w32-0000000000000000000000\build\src\widget\windows\nsWindow.cpp(3784) : error C2065: 'NS_MOUSE_EXIT' : undeclared identifier

I found I didn't resolve the conflict completely. Here is the updated version.
Sorry for the missing part.

Hi Neil,

How should I deal with these unclassified cases?
Flags: needinfo?(enndeakin)
The one failure there looks like bug 1159150, so you should be ok. If you are happy with the patch you can mark it for review. I can review it if you like but you might want to ask for review and/or feedback from bugs@pettay.fi

Hi Neil,

I update the patch as Olli recommended. What is the next step to push my patch into the repository?

By the way, can I take this bug and become assignee? And what is the permission I need to take bugs by myself?
Flags: needinfo?(enndeakin)
You can add the checkin-needed keyword to the 'Keywords' field and someone will check the patch in.

You can assign bugs to yourself by setting the Assigned field. (Click the 'take' link). Or maybe you don't have permission? I'll set the assigned field to you for this bug.

Generally to get more permissions (for bugzilla, to check in, etc), you need someone or several people to vouch for you. See https://www.mozilla.org/en-US/about/governance/policies/commit/ for more information. You will likely need to have worked on a couple of bugs with other people to get higher privileges. It looks like you could get access to the try server already at least.
