Actually, this reminds me of one thing I've been meaning to ask about this regarding moving JSCore export definitions into the headers. The export symbol definitions (such as JS_EXPORTDATA, JS_EXPORT_PRIVATE, etc.) are defined multiple ways in multiple places (e.g. various project's config.h headers), and I was hoping we could move towards having some sort of WTF_EXPORT and WTF_IMPORT macros, then set macros like JS_EXPORTDATA based on them, so that we're not continually copying and pasting the same macro setting logic into each project's config.h or somewhere else. Kind of like a project-wide equivalent to JSBase.h for JSCore public API. You can see this quite well how many places these macros are copied over to by looking at the last patch for https://bugs.webkit.org/show_bug.cgi?id=27551, but that's a pretty large patch, so a simpler case which clearly shows how we need to copy and paste these macros each time a new component needs export symbol control can be found in a patch I recently submitted here: https://bugs.webkit.org/show_bug.cgi?id=43204 One thing that seems to make consolidating these macros into one location tricky is that WTF seems the most suitable place for it, but it is still technically a private implementation detail of JSCore, and there seems to be with some ports a great deal of effort put into isolating each project's headers and sources from the other projects. (With the Windows build particularly, I noticed a lot of copying of headers and even some implementation files from one project to another using the build directory as an intermediary.) I'd like to have some file that could be included by everything from JSCore to DumpRenderTree and, at least indirectly, by client apps (e.g. when I use those macros in wxWebKit API), without having that sort of copying set up in all the ports. Is there currently an appropriate place for such a thing to go? If not, any suggestions on the best way to approach this? Or am I missing some obvious and simple solution here?
