Not yet ready for review, but wanted to ask your opinion on this approach: 1) build separate target called WebCoreTestSupport in WebCore project, which produces libWebCoreTestSupport.a 2) when building, InternalsInjector.h is copied to WebCoreTestSupport/PrivateHeaders/InternalsInjector.h; 3) the DumpRenderTree project links in libWebCoreTestSupport.a and refers to InternalsInjector.h; 4) allowing the DRT code to call into to InternalsInjector to inject window.internals.

WebKit2 is a bit more difficult. Because the layout test controller code is in a bundle, I can't link in WebCore symbols there. I need to look more at how WebKit2 works -- or perhaps Sam can just point me at the right place.

Comment 17 2011-05-19 11:50:50 PDT

If that's ok, I'll land this with a small change to WebCore.xcodeproj -- I'll add an extra "All" target, which depends on both WebCore and WebCoreTestSupport. This would make the project structure more consistent with DumpRenderTree.xcodeproj and WebKit2.xcodeproj.

Comment 23 2011-05-19 13:21:26 PDT

Ultimately, the issue was in inability to manage symbols export. andersca and myself threw fixes at the tree for a while, but stopped after seeing this in the latest fix attempt. ERROR: WebCore has a weak vtable in it (/Volumes/Big/WebKit-BuildSlave/leopard-intel-release/build/WebKitBuild/Release/WebCore.framework/Versions/A/WebCore) ERROR: Fix by making sure the first virtual function in each of these classes is not an inline: ERROR: class WebCore::JSDOMWrapper I fear we're solving a problem with another problem. This patch barely touched WebCore internals, and we still had way too much fun attempting to manage the exports. So instead of plumbing stuff through ports' WebKit layers, we would have to manage these ports' exports. Does anyone have any bright ideas on improving the situation?

> Does anyone have any bright ideas on improving the situation? Following exciting intracranial discussion, I've concluded that this is still the right approach. Even though we will have to occasionally unpuzzle weird exported symbol problems, it's still better and less wasteful then plumbing this through the WebKit API layer.

(In reply to comment #24) > Created an attachment (id=94331) [details] > Harder, better, faster, stronger. This patch differs from the last one in: * Addition of WebCoreTestSupport.xcconfig file * A fix for the Chromium component build * Accumulating all of the exported symbol fixes that we threw at the tree while landing last time * A funky workaround for "weak external vtable" issue in JSDOMWrapper. I don't love it, but it appears to be the only rational way. Appreciate any um.. pointers!

> better and less wasteful then plumbing this through the WebKit API layer. I'd like to use this occasion to re-emphasize a point I've been making at the contributor meeting. This functionality should not be a replacement for tests that need to be end to end, but the contributor is unwilling to do WebKit plumbing for some reason. I'm sure that we'll have exciting discussions for each specific case for a while, until we figure out the best practices. Let's try to have these early enough in the process, before code is written and a patch is up for review!
