Bug 130013 – [CSS Grid Layout] Enable runtime feature if feature flag is enabled

• Component: CSS
• Status: RESOLVED FIXED

[Manuel Rego Casasnovas]

Currently in development builds ENABLE_CSS_GRID_LAYOUT is true, however the runtime feature is still false so you cannot test it without doing a manual build.

It would be nice to enable the runtime flag when ENABLE_CSS_GRID_LAYOUT is true, otherwise it doesn't have too much sense to compile the core related to CSS Grid Layout if  you're not going to be able to use it.

Finally keeping layout test but checking that the runtime feature can be disabled.

This is only changing WebKit2. What about WebKit1?

Changing WK1 code too.

Anyway, maybe it would be a better idea to make the runtime feature true directly in WebCore/page/Settings.in.

So if you compile with ENBALE_CSS_GRID_LAYOUT the feature will be enabled by default (and you have still the chance to disable the runtime feature if needed). And if you don't compile with ENBALE_CSS_GRID_LAYOUT the feature won't work as expected.

If you prefer this kind of change, I can change the patch and do something like that. What do you think?
