Bug 179063 – Add a FileSystem namespace to FileSystem.cpp

• Component: Platform
• Status: RESOLVED FIXED

[Christopher Reid]

I am planning on moving FileSystem to PAL soon. Before work is done to move it, I'm working on cleaning up and updating the code.
The functions of filesystem are global to the WebCore namespace. Adding a FileSystem namespace will help avoid naming collisions with these functions.

I’m not thrilled by this change; I don’t really know what specific name conflicts this is preventing. But I guess it’s OK.

The file list in this change log is a mess. For example, it’s not great to just leave in all sorts of erroneous "deleted" lines for functions moved inside a namespace. The point of the change log generation tool is to start the change log for you. It’s not great to just leave all the lines in there without looking them over. For a global replace like this, might even want to leave out all the function names.

Do we really need the WebCore prefix here? This code is in a namespace nested inside the WebCore namespace. I’m surprised this is required.

That's good to know, I'll clean up the ChangeLogs and I can take out all the touched function names.

It actually looks fine without that WebCore namespace, I'll take it out.
