Bug 128594 – [WK2][WTR] Implement overridePreference() for non-boolean values

• Status: NEW
• Component: WebKit Misc.

[Dániel Bátyai]

TestRunner::overridePreference() is currently only implemented for boolean preferences

[Simon Fraser (smfr)]

When is overridePreference() still needed?

[Frédéric Wang (:fredw)]

In bug 171914, I have to disable platform/mac/fast/frames/flattening/set-preference.html because overridePreference does not support non-boolean values.

22:36:46 - smfr : why do you need to use overridePreference?
22:36:56 - smfr : tests can just poke at internals.settings
22:37:11 - smfr : or is it too late after a test starts?
22:41:36 - fredw : I don't remember exactly. I believe internals.settings is enough. But other settings in mac/DumpRenderTree.mm and tests set a default value via this overridePreference so I thought it would be a bit inconsistent.
22:43:26 - smfr : i think many tests that use overridePreference pre-date internals.settings and could just be converted

Here are the list of tests still using overridePreference:

I agree with Simon. We should just use internal.settings if what is being toggled is a WebCore::Setting.

overridePreference should be used rarely. I think the only valid case is for WebKit level settings not WebCore settings. Even still those could probably move to something else that executes before the test loads.

OK, I uploaded a tentative patch on bug 173714. After that, the remaining settings are:

WebKit2AsynchronousPluginInitializationEnabled
WebKit2AsynchronousPluginInitializationEnabledForAllPlugins
WebKitAllowDisplayingInsecureContent
WebKitCSSRegionsEnabled
WebKitDefaultTextEncodingName
WebKitDisplayImagesKey
WebKitJavaScriptEnabled
WebKitLoadSiteIconsKey
WebKitShouldInvertColors
WebKitStorageBlockingPolicy
WebKitTabToLinksPreferenceKey
WebKitUsesPageCachePreferenceKey

Also:

WebKitHiddenPageDOMTimerThrottlingEnabled (bug 173713)
WebKitDefaultFontSize, MinimumFontSize (non-boolean, need to add something to Internals.idl to expose them)
