LayoutTests/platform/chromium/fast/dom/Window/window-properties-performance-expected.txt:1
 +  This test dumps all of the properties that are reachable from the window.webkitPerformance object, along with their types.
hmm, it seems like we'd want to invert things here so that the expected
results are the shared results, and then just add the test to the Skipped
list for other ports.  at least, this is what we did for webkitNotifications.

Just to be sure I understand you, the idea is to invert all expectations, not just for window-properties-performance-expected.txt. Right?

After thinking about this, that is the only thing that makes sense. Patch updated.

Oh, and there was one strange thing.

When I use run_webkit_tests.bat, it doesn't seem to be using the default expectations even though there are no longer chromium specific expectations. Am I passing it the wrong flags or does it fall back to platform/{mac|win|gtk} before the default?

If the fallback path is chromium-{mac|win|gtk} => chromium => {mac|win|gtk} => default, then I need to copy the default expectations to the chromium port in this patch.

Okay, it looks like that was the fallback path. So I copied the default passing expectations to the chromium port. Should be good to go now.

I updated this patch per our offline discussion to skip instead of FAIL for other platforms. Man, that is so much better!

I also opened bugs to enable for each port.

LayoutTests/platform/chromium/fast/dom/Window/window-properties-performance-expected.txt:1
 +  This test dumps all of the properties that are reachable from the window.webkitPerformance object, along with their types.
this file should be unnecessary given the one here:
LayoutTests/fast/dom/Window/window-properties-performance-expected.txt

LayoutTests/platform/gtk/Skipped:5872
 +  http/tests/misc/webtiming-two-redirects.html
it seems like you should add fast/dom/Window/window-properties-performance.html to
the Skipped files as well.  what point is there in testing that webkitPerformance
is undefined for the ports that don't have webtiming enabled?  i think it is better
to skip the test for those ports.  otherwise, to enable the feature, they have to
delete the expected failure results, which is a bit unusual.

Just to make sure I wasn't crazy, I tracked this down. layout_tests/port/chromium_win.py::baseline_search_path() defines the search path for Vista as [chromium-win-vista, chromium-win, chromium, win, mac].

This means that if there are platform specific results in win or mac, there need to be platform specific results in chromium.

But this is all moot as, per your comment, I've removed the platform specific results in favor of adding window-properties-performance.html to Skipped.

My original thought was that it is valuable to keep that test with differing expectations to verify that window.webkitPerformance isn't exposed when the WEB_TIMING flag is off. But I see your point. Fixed and noted for the future.

Skip window-properties-performance.html on disabled ports

r=me

(we pick up results from platform/{mac,win} because often times we have similar
 expectations, especially for tests that output the render tree.)
